Variables
~~~~~~~~~

Note that this list is non-comprehensive and not necessarily complete.
For command-specific variables, you will find a more detailed description
in the appropriate manual page.

Other git-related tools may and do use their own variables.  When
inventing new variables for use in your own tool, make sure their
names do not conflict with those that are used by Git itself and
other popular tools, and describe them in your documentation.

add.ignoreErrors::
add.ignore-errors (deprecated)::
	Tells 'git add' to continue adding files when some files cannot be
	added due to indexing errors. Equivalent to the `--ignore-errors`
	option of linkgit:git-add[1].  `add.ignore-errors` is deprecated,
	as it does not follow the usual naming convention for configuration
	variables.

add.interactive.useBuiltin::
	Unused configuration variable. Used in Git versions v2.25.0 to
	v2.36.0 to enable the built-in version of linkgit:git-add[1]'s
	interactive mode, which then became the default in Git
	versions v2.37.0 to v2.39.0.

advice.*::
	These variables control various optional help messages designed to
	aid new users.  When left unconfigured, Git will give the message
	alongside instructions on how to squelch it.  You can tell Git
	that you do not need the help message by setting these to `false`:
+
--
	addEmbeddedRepo::
		Shown when the user accidentally adds one
		git repo inside of another.
	addEmptyPathspec::
		Shown when the user runs `git add` without providing
		the pathspec parameter.
	addIgnoredFile::
		Shown when the user attempts to add an ignored file to
		the index.
	amWorkDir::
		Shown when linkgit:git-am[1] fails to apply a patch
		file, to tell the user the location of the file.
	ambiguousFetchRefspec::
		Shown when a fetch refspec for multiple remotes maps to
		the same remote-tracking branch namespace and causes branch
		tracking set-up to fail.
	checkoutAmbiguousRemoteBranchName::
		Shown when the argument to
		linkgit:git-checkout[1] and linkgit:git-switch[1]
		ambiguously resolves to a
		remote tracking branch on more than one remote in
		situations where an unambiguous argument would have
		otherwise caused a remote-tracking branch to be
		checked out. See the `checkout.defaultRemote`
		configuration variable for how to set a given remote
		to be used by default in some situations where this
		advice would be printed.
	commitBeforeMerge::
		Shown when linkgit:git-merge[1] refuses to
		merge to avoid overwriting local changes.
	detachedHead::
		Shown when the user uses
		linkgit:git-switch[1] or linkgit:git-checkout[1]
		to move to the detached HEAD state, to tell the user how
		to create a local branch after the fact.
	diverging::
		Shown when a fast-forward is not possible.
	fetchShowForcedUpdates::
		Shown when linkgit:git-fetch[1] takes a long time
		to calculate forced updates after ref updates, or to warn
		that the check is disabled.
	forceDeleteBranch::
		Shown when the user tries to delete a not fully merged
		branch without the force option set.
	ignoredHook::
		Shown when a hook is ignored because the hook is not
		set as executable.
	implicitIdentity::
		Shown when the user's information is guessed from the
		system username and domain name, to tell the user how to
		set their identity configuration.
	mergeConflict::
		Shown when various commands stop because of conflicts.
	nestedTag::
		Shown when a user attempts to recursively tag a tag object.
	pushAlreadyExists::
		Shown when linkgit:git-push[1] rejects an update that
		does not qualify for fast-forwarding (e.g., a tag.)
	pushFetchFirst::
		Shown when linkgit:git-push[1] rejects an update that
		tries to overwrite a remote ref that points at an
		object we do not have.
	pushNeedsForce::
		Shown when linkgit:git-push[1] rejects an update that
		tries to overwrite a remote ref that points at an
		object that is not a commit-ish, or make the remote
		ref point at an object that is not a commit-ish.
	pushNonFFCurrent::
		Shown when linkgit:git-push[1] fails due to a
		non-fast-forward update to the current branch.
	pushNonFFMatching::
		Shown when the user ran linkgit:git-push[1] and pushed
		"matching refs" explicitly (i.e. used `:`, or
		specified a refspec that isn't the current branch) and
		it resulted in a non-fast-forward error.
	pushRefNeedsUpdate::
		Shown when linkgit:git-push[1] rejects a forced update of
		a branch when its remote-tracking ref has updates that we
		do not have locally.
	pushUnqualifiedRefname::
		Shown when linkgit:git-push[1] gives up trying to
		guess based on the source and destination refs what
		remote ref namespace the source belongs in, but where
		we can still suggest that the user push to either
		`refs/heads/*` or `refs/tags/*` based on the type of the
		source object.
	pushUpdateRejected::
		Set this variable to `false` if you want to disable
		`pushNonFFCurrent`, `pushNonFFMatching`, `pushAlreadyExists`,
		`pushFetchFirst`, `pushNeedsForce`, and `pushRefNeedsUpdate`
		simultaneously.
	refSyntax::
		Shown when the user provides an illegal ref name, to
		tell the user about the ref syntax documentation.
	resetNoRefresh::
		Shown when linkgit:git-reset[1] takes more than 2
		seconds to refresh the index after reset, to tell the user
		that they can use the `--no-refresh` option.
	resolveConflict::
		Shown by various commands when conflicts
		prevent the operation from being performed.
	rmHints::
		Shown on failure in the output of linkgit:git-rm[1], to
		give directions on how to proceed from the current state.
	sequencerInUse::
		Shown when a sequencer command is already in progress.
	skippedCherryPicks::
		Shown when linkgit:git-rebase[1] skips a commit that has already
		been cherry-picked onto the upstream branch.
	statusAheadBehind::
		Shown when linkgit:git-status[1] computes the ahead/behind
		counts for a local ref compared to its remote tracking ref,
		and that calculation takes longer than expected. Will not
		appear if `status.aheadBehind` is false or the option
		`--no-ahead-behind` is given.
	statusHints::
		Show directions on how to proceed from the current
		state in the output of linkgit:git-status[1], in
		the template shown when writing commit messages in
		linkgit:git-commit[1], and in the help message shown
		by linkgit:git-switch[1] or
		linkgit:git-checkout[1] when switching branches.
	statusUoption::
		Shown when linkgit:git-status[1] takes more than 2
		seconds to enumerate untracked files, to tell the user that
		they can use the `-u` option.
	submoduleAlternateErrorStrategyDie::
		Shown when a submodule.alternateErrorStrategy option
		configured to "die" causes a fatal error.
	submoduleMergeConflict::
		Advice shown when a non-trivial submodule merge conflict is
		encountered.
	submodulesNotUpdated::
		Shown when a user runs a submodule command that fails
		because `git submodule update --init` was not run.
	suggestDetachingHead::
		Shown when linkgit:git-switch[1] refuses to detach HEAD
		without the explicit `--detach` option.
	updateSparsePath::
		Shown when either linkgit:git-add[1] or linkgit:git-rm[1]
		is asked to update index entries outside the current sparse
		checkout.
	waitingForEditor::
		Shown when Git is waiting for editor input. Relevant
		when e.g. the editor is not launched inside the terminal.
	worktreeAddOrphan::
		Shown when the user tries to create a worktree from an
		invalid reference, to tell the user how to create a new unborn
		branch instead.
--

alias.*::
	Command aliases for the linkgit:git[1] command wrapper - e.g.
	after defining `alias.last = cat-file commit HEAD`, the invocation
	`git last` is equivalent to `git cat-file commit HEAD`. To avoid
	confusion and troubles with script usage, aliases that
	hide existing Git commands are ignored. Arguments are split by
	spaces, the usual shell quoting and escaping are supported.
	A quote pair or a backslash can be used to quote them.
+
Note that the first word of an alias does not necessarily have to be a
command. It can be a command-line option that will be passed into the
invocation of `git`. In particular, this is useful when used with `-c`
to pass in one-time configurations or `-p` to force pagination. For example,
`loud-rebase = -c commit.verbose=true rebase` can be defined such that
running `git loud-rebase` would be equivalent to
`git -c commit.verbose=true rebase`. Also, `ps = -p status` would be a
helpful alias since `git ps` would paginate the output of `git status`
where the original command does not.
+
If the alias expansion is prefixed with an exclamation point,
it will be treated as a shell command.  For example, defining
`alias.new = !gitk --all --not ORIG_HEAD`, the invocation
`git new` is equivalent to running the shell command
`gitk --all --not ORIG_HEAD`.  Note that shell commands will be
executed from the top-level directory of a repository, which may
not necessarily be the current directory.
`GIT_PREFIX` is set as returned by running `git rev-parse --show-prefix`
from the original current directory. See linkgit:git-rev-parse[1].

am.keepcr::
	If true, git-am will call git-mailsplit for patches in mbox format
	with parameter `--keep-cr`. In this case git-mailsplit will
	not remove `\r` from lines ending with `\r\n`. Can be overridden
	by giving `--no-keep-cr` from the command line.
	See linkgit:git-am[1], linkgit:git-mailsplit[1].

am.threeWay::
	By default, `git am` will fail if the patch does not apply cleanly. When
	set to true, this setting tells `git am` to fall back on 3-way merge if
	the patch records the identity of blobs it is supposed to apply to and
	we have those blobs available locally (equivalent to giving the `--3way`
	option from the command line). Defaults to `false`.
	See linkgit:git-am[1].

apply.ignoreWhitespace::
	When set to 'change', tells 'git apply' to ignore changes in
	whitespace, in the same way as the `--ignore-space-change`
	option.
	When set to one of: no, none, never, false, it tells 'git apply' to
	respect all whitespace differences.
	See linkgit:git-apply[1].

apply.whitespace::
	Tells 'git apply' how to handle whitespace, in the same way
	as the `--whitespace` option. See linkgit:git-apply[1].

attr.tree::
	A reference to a tree in the repository from which to read attributes,
	instead of the `.gitattributes` file in the working tree. In a bare
	repository, this defaults to `HEAD:.gitattributes`. If the value does
	not resolve to a valid tree object, an empty tree is used instead.
	When the `GIT_ATTR_SOURCE` environment variable or `--attr-source`
	command line option are used, this configuration variable has no effect.

blame.blankBoundary::
	Show blank commit object name for boundary commits in
	linkgit:git-blame[1]. This option defaults to false.

blame.coloring::
	This determines the coloring scheme to be applied to blame
	output. It can be 'repeatedLines', 'highlightRecent',
	or 'none' which is the default.

blame.date::
	Specifies the format used to output dates in linkgit:git-blame[1].
	If unset the iso format is used. For supported values,
	see the discussion of the `--date` option at linkgit:git-log[1].

blame.showEmail::
	Show the author email instead of author name in linkgit:git-blame[1].
	This option defaults to false.

blame.showRoot::
	Do not treat root commits as boundaries in linkgit:git-blame[1].
	This option defaults to false.

blame.ignoreRevsFile::
	Ignore revisions listed in the file, one unabbreviated object name per
	line, in linkgit:git-blame[1].  Whitespace and comments beginning with
	`#` are ignored.  This option may be repeated multiple times.  Empty
	file names will reset the list of ignored revisions.  This option will
	be handled before the command line option `--ignore-revs-file`.

blame.markUnblamableLines::
	Mark lines that were changed by an ignored revision that we could not
	attribute to another commit with a '*' in the output of
	linkgit:git-blame[1].

blame.markIgnoredLines::
	Mark lines that were changed by an ignored revision that we attributed to
	another commit with a '?' in the output of linkgit:git-blame[1].

branch.autoSetupMerge::
	Tells 'git branch', 'git switch' and 'git checkout' to set up new branches
	so that linkgit:git-pull[1] will appropriately merge from the
	starting point branch. Note that even if this option is not set,
	this behavior can be chosen per-branch using the `--track`
	and `--no-track` options. The valid settings are: `false` -- no
	automatic setup is done; `true` -- automatic setup is done when the
	starting point is a remote-tracking branch; `always` --
	automatic setup is done when the starting point is either a
	local branch or remote-tracking branch; `inherit` -- if the starting point
	has a tracking configuration, it is copied to the new
	branch; `simple` -- automatic setup is done only when the starting point
	is a remote-tracking branch and the new branch has the same name as the
	remote branch. This option defaults to true.

branch.autoSetupRebase::
	When a new branch is created with 'git branch', 'git switch' or 'git checkout'
	that tracks another branch, this variable tells Git to set
	up pull to rebase instead of merge (see "branch.<name>.rebase").
	When `never`, rebase is never automatically set to true.
	When `local`, rebase is set to true for tracked branches of
	other local branches.
	When `remote`, rebase is set to true for tracked branches of
	remote-tracking branches.
	When `always`, rebase will be set to true for all tracking
	branches.
	See "branch.autoSetupMerge" for details on how to set up a
	branch to track another branch.
	This option defaults to never.

branch.sort::
	This variable controls the sort ordering of branches when displayed by
	linkgit:git-branch[1]. Without the "--sort=<value>" option provided, the
	value of this variable will be used as the default.
	See linkgit:git-for-each-ref[1] field names for valid values.

branch.<name>.remote::
	When on branch <name>, it tells 'git fetch' and 'git push'
	which remote to fetch from or push to.  The remote to push to
	may be overridden with `remote.pushDefault` (for all branches).
	The remote to push to, for the current branch, may be further
	overridden by `branch.<name>.pushRemote`.  If no remote is
	configured, or if you are not on any branch and there is more than
	one remote defined in the repository, it defaults to `origin` for
	fetching and `remote.pushDefault` for pushing.
	Additionally, `.` (a period) is the current local repository
	(a dot-repository), see `branch.<name>.merge`'s final note below.

branch.<name>.pushRemote::
	When on branch <name>, it overrides `branch.<name>.remote` for
	pushing.  It also overrides `remote.pushDefault` for pushing
	from branch <name>.  When you pull from one place (e.g. your
	upstream) and push to another place (e.g. your own publishing
	repository), you would want to set `remote.pushDefault` to
	specify the remote to push to for all branches, and use this
	option to override it for a specific branch.

branch.<name>.merge::
	Defines, together with branch.<name>.remote, the upstream branch
	for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
	branch to merge and can also affect 'git push' (see push.default).
	When in branch <name>, it tells 'git fetch' the default
	refspec to be marked for merging in FETCH_HEAD. The value is
	handled like the remote part of a refspec, and must match a
	ref which is fetched from the remote given by
	"branch.<name>.remote".
	The merge information is used by 'git pull' (which first calls
	'git fetch') to lookup the default branch for merging. Without
	this option, 'git pull' defaults to merge the first refspec fetched.
	Specify multiple values to get an octopus merge.
	If you wish to setup 'git pull' so that it merges into <name> from
	another branch in the local repository, you can point
	branch.<name>.merge to the desired branch, and use the relative path
	setting `.` (a period) for branch.<name>.remote.

branch.<name>.mergeOptions::
	Sets default options for merging into branch <name>. The syntax and
	supported options are the same as those of linkgit:git-merge[1], but
	option values containing whitespace characters are currently not
	supported.

branch.<name>.rebase::
	When true, rebase the branch <name> on top of the fetched branch,
	instead of merging the default branch from the default remote when
	"git pull" is run. See "pull.rebase" for doing this in a non
	branch-specific manner.
+
When `merges` (or just 'm'), pass the `--rebase-merges` option to 'git rebase'
so that the local merge commits are included in the rebase (see
linkgit:git-rebase[1] for details).
+
When the value is `interactive` (or just 'i'), the rebase is run in interactive
mode.
+
*NOTE*: this is a possibly dangerous operation; do *not* use
it unless you understand the implications (see linkgit:git-rebase[1]
for details).

branch.<name>.description::
	Branch description, can be edited with
	`git branch --edit-description`. Branch description is
	automatically added to the format-patch cover letter or
	request-pull summary.

browser.<tool>.cmd::
	Specify the command to invoke the specified browser. The
	specified command is evaluated in shell with the URLs passed
	as arguments. (See linkgit:git-web{litdd}browse[1].)

browser.<tool>.path::
	Override the path for the given tool that may be used to
	browse HTML help (see `-w` option in linkgit:git-help[1]) or a
	working repository in gitweb (see linkgit:git-instaweb[1]).

bundle.*::
	The `bundle.*` keys may appear in a bundle list file found via the
	`git clone --bundle-uri` option. These keys currently have no effect
	if placed in a repository config file, though this will change in the
	future. See link:technical/bundle-uri.html[the bundle URI design
	document] for more details.

bundle.version::
	This integer value advertises the version of the bundle list format
	used by the bundle list. Currently, the only accepted value is `1`.

bundle.mode::
	This string value should be either `all` or `any`. This value describes
	whether all of the advertised bundles are required to unbundle a
	complete understanding of the bundled information (`all`) or if any one
	of the listed bundle URIs is sufficient (`any`).

bundle.heuristic::
	If this string-valued key exists, then the bundle list is designed to
	work well with incremental `git fetch` commands. The heuristic signals
	that there are additional keys available for each bundle that help
	determine which subset of bundles the client should download. The
	only value currently understood is `creationToken`.

bundle.<id>.*::
	The `bundle.<id>.*` keys are used to describe a single item in the
	bundle list, grouped under `<id>` for identification purposes.

bundle.<id>.uri::
	This string value defines the URI by which Git can reach the contents
	of this `<id>`. This URI may be a bundle file or another bundle list.

checkout.defaultRemote::
	When you run `git checkout <something>`
	or `git switch <something>` and only have one
	remote, it may implicitly fall back on checking out and
	tracking e.g. `origin/<something>`. This stops working as soon
	as you have more than one remote with a `<something>`
	reference. This setting allows for setting the name of a
	preferred remote that should always win when it comes to
	disambiguation. The typical use-case is to set this to
	`origin`.
+
Currently this is used by linkgit:git-switch[1] and
linkgit:git-checkout[1] when `git checkout <something>`
or `git switch <something>`
will checkout the `<something>` branch on another remote,
and by linkgit:git-worktree[1] when `git worktree add` refers to a
remote branch. This setting might be used for other checkout-like
commands or functionality in the future.

checkout.guess::
	Provides the default value for the `--guess` or `--no-guess`
	option in `git checkout` and `git switch`. See
	linkgit:git-switch[1] and linkgit:git-checkout[1].

checkout.workers::
	The number of parallel workers to use when updating the working tree.
	The default is one, i.e. sequential execution. If set to a value less
	than one, Git will use as many workers as the number of logical cores
	available. This setting and `checkout.thresholdForParallelism` affect
	all commands that perform checkout. E.g. checkout, clone, reset,
	sparse-checkout, etc.
+
Note: Parallel checkout usually delivers better performance for repositories
located on SSDs or over NFS. For repositories on spinning disks and/or machines
with a small number of cores, the default sequential checkout often performs
better. The size and compression level of a repository might also influence how
well the parallel version performs.

checkout.thresholdForParallelism::
	When running parallel checkout with a small number of files, the cost
	of subprocess spawning and inter-process communication might outweigh
	the parallelization gains. This setting allows you to define the minimum
	number of files for which parallel checkout should be attempted. The
	default is 100.

clean.requireForce::
	A boolean to make git-clean refuse to delete files unless -f
	is given. Defaults to true.

`clone.defaultRemoteName`::
	The name of the remote to create when cloning a repository.  Defaults to
	`origin`.
	It can be overridden by passing the `--origin` command-line
	option to linkgit:git-clone[1].

`clone.rejectShallow`::
	Reject cloning a repository if it is a shallow one; this can be overridden by
	passing the `--reject-shallow` option on the command line.
	See linkgit:git-clone[1].

`clone.filterSubmodules`::
	If a partial clone filter is provided (see `--filter` in
	linkgit:git-rev-list[1]) and `--recurse-submodules` is used, also apply
	the filter to submodules.

color.advice::
	A boolean to enable/disable color in hints (e.g. when a push
	failed, see `advice.*` for a list).  May be set to `always`,
	`false` (or `never`) or `auto` (or `true`), in which case colors
	are used only when the error output goes to a terminal. If
	unset, then the value of `color.ui` is used (`auto` by default).

color.advice.hint::
	Use customized color for hints.

color.blame.highlightRecent::
	Specify the line annotation color for `git blame --color-by-age`
	depending upon the age of the line.
+
This setting should be set to a comma-separated list of color and
date settings, starting and ending with a color, the dates should be
set from oldest to newest. The metadata will be colored with the
specified colors if the line was introduced before the given
timestamp, overwriting older timestamped colors.
+
Instead of an absolute timestamp relative timestamps work as well,
e.g. `2.weeks.ago` is valid to address anything older than 2 weeks.
+
It defaults to `blue,12 month ago,white,1 month ago,red`, which
colors everything older than one year blue, recent changes between
one month and one year old are kept white, and lines introduced
within the last month are colored red.

color.blame.repeatedLines::
	Use the specified color to colorize line annotations for
	`git blame --color-lines`, if they come from the same commit as the
	preceding line. Defaults to cyan.

color.branch::
	A boolean to enable/disable color in the output of
	linkgit:git-branch[1]. May be set to `always`,
	`false` (or `never`) or `auto` (or `true`), in which case colors are used
	only when the output is to a terminal. If unset, then the
	value of `color.ui` is used (`auto` by default).

color.branch.<slot>::
	Use customized color for branch coloration. `<slot>` is one of
	`current` (the current branch), `local` (a local branch),
	`remote` (a remote-tracking branch in refs/remotes/),
	`upstream` (upstream tracking branch), `plain` (other
	refs).

color.diff::
	Whether to use ANSI escape sequences to add color to patches.
	If this is set to `always`, linkgit:git-diff[1],
	linkgit:git-log[1], and linkgit:git-show[1] will use color
	for all patches.  If it is set to `true` or `auto`, those
	commands will only use color when output is to the terminal.
	If unset, then the value of `color.ui` is used (`auto` by
	default).
+
This does not affect linkgit:git-format-patch[1] or the
'git-diff-{asterisk}' plumbing commands.  Can be overridden on the
command line with the `--color[=<when>]` option.

color.diff.<slot>::
	Use customized color for diff colorization.  `<slot>` specifies
	which part of the patch to use the specified color, and is one
	of `context` (context text - `plain` is a historical synonym),
	`meta` (metainformation), `frag`
	(hunk header), 'func' (function in hunk header), `old` (removed lines),
	`new` (added lines), `commit` (commit headers), `whitespace`
	(highlighting whitespace errors), `oldMoved` (deleted lines),
	`newMoved` (added lines), `oldMovedDimmed`, `oldMovedAlternative`,
	`oldMovedAlternativeDimmed`, `newMovedDimmed`, `newMovedAlternative`
	`newMovedAlternativeDimmed` (See the '<mode>'
	setting of '--color-moved' in linkgit:git-diff[1] for details),
	`contextDimmed`, `oldDimmed`, `newDimmed`, `contextBold`,
	`oldBold`, and `newBold` (see linkgit:git-range-diff[1] for details).

color.decorate.<slot>::
	Use customized color for 'git log --decorate' output.  `<slot>` is one
	of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local
	branches, remote-tracking branches, tags, stash and HEAD, respectively
	and `grafted` for grafted commits.

color.grep::
	When set to `always`, always highlight matches.  When `false` (or
	`never`), never.  When set to `true` or `auto`, use color only
	when the output is written to the terminal.  If unset, then the
	value of `color.ui` is used (`auto` by default).

color.grep.<slot>::
	Use customized color for grep colorization.  `<slot>` specifies which
	part of the line to use the specified color, and is one of
+
--
`context`;;
	non-matching text in context lines (when using `-A`, `-B`, or `-C`)
`filename`;;
	filename prefix (when not using `-h`)
`function`;;
	function name lines (when using `-p`)
`lineNumber`;;
	line number prefix (when using `-n`)
`column`;;
	column number prefix (when using `--column`)
`match`;;
	matching text (same as setting `matchContext` and `matchSelected`)
`matchContext`;;
	matching text in context lines
`matchSelected`;;
	matching text in selected lines. Also, used to customize the following
	linkgit:git-log[1] subcommands: `--grep`, `--author`, and `--committer`.
`selected`;;
	non-matching text in selected lines. Also, used to customize the
	following linkgit:git-log[1] subcommands: `--grep`, `--author` and
	`--committer`.
`separator`;;
	separators between fields on a line (`:`, `-`, and `=`)
	and between hunks (`--`)
--

color.interactive::
	When set to `always`, always use colors for interactive prompts
	and displays (such as those used by "git-add --interactive" and
	"git-clean --interactive"). When false (or `never`), never.
	When set to `true` or `auto`, use colors only when the output is
	to the terminal. If unset, then the value of `color.ui` is
	used (`auto` by default).

color.interactive.<slot>::
	Use customized color for 'git add --interactive' and 'git clean
	--interactive' output. `<slot>` may be `prompt`, `header`, `help`
	or `error`, for four distinct types of normal output from
	interactive commands.

color.pager::
	A boolean to specify whether `auto` color modes should colorize
	output going to the pager. Defaults to true; set this to false
	if your pager does not understand ANSI color codes.

color.push::
	A boolean to enable/disable color in push errors. May be set to
	`always`, `false` (or `never`) or `auto` (or `true`), in which
	case colors are used only when the error output goes to a terminal.
	If unset, then the value of `color.ui` is used (`auto` by default).

color.push.error::
	Use customized color for push errors.

color.remote::
	If set, keywords at the start of the line are highlighted. The
	keywords are "error", "warning", "hint" and "success", and are
	matched case-insensitively. May be set to `always`, `false` (or
	`never`) or `auto` (or `true`). If unset, then the value of
	`color.ui` is used (`auto` by default).

color.remote.<slot>::
	Use customized color for each remote keyword. `<slot>` may be
	`hint`, `warning`, `success` or `error` which match the
	corresponding keyword.

color.showBranch::
	A boolean to enable/disable color in the output of
	linkgit:git-show-branch[1]. May be set to `always`,
	`false` (or `never`) or `auto` (or `true`), in which case colors are used
	only when the output is to a terminal. If unset, then the
	value of `color.ui` is used (`auto` by default).

color.status::
	A boolean to enable/disable color in the output of
	linkgit:git-status[1]. May be set to `always`,
	`false` (or `never`) or `auto` (or `true`), in which case colors are used
	only when the output is to a terminal. If unset, then the
	value of `color.ui` is used (`auto` by default).

color.status.<slot>::
	Use customized color for status colorization. `<slot>` is
	one of `header` (the header text of the status message),
	`added` or `updated` (files which are added but not committed),
	`changed` (files which are changed but not added in the index),
	`untracked` (files which are not tracked by Git),
	`branch` (the current branch),
	`nobranch` (the color the 'no branch' warning is shown in, defaulting
	to red),
	`localBranch` or `remoteBranch` (the local and remote branch names,
	respectively, when branch and tracking information is displayed in the
	status short-format), or
	`unmerged` (files which have unmerged changes).

color.transport::
	A boolean to enable/disable color when pushes are rejected. May be
	set to `always`, `false` (or `never`) or `auto` (or `true`), in which
	case colors are used only when the error output goes to a terminal.
	If unset, then the value of `color.ui` is used (`auto` by default).

color.transport.rejected::
	Use customized color when a push was rejected.

color.ui::
	This variable determines the default value for variables such
	as `color.diff` and `color.grep` that control the use of color
	per command family. Its scope will expand as more commands learn
	configuration to set a default for the `--color` option.  Set it
	to `false` or `never` if you prefer Git commands not to use
	color unless enabled explicitly with some other configuration
	or the `--color` option. Set it to `always` if you want all
	output not intended for machine consumption to use color, to
	`true` or `auto` (this is the default since Git 1.8.4) if you
	want such output to use color when written to the terminal.

column.ui::
	Specify whether supported commands should output in columns.
	This variable consists of a list of tokens separated by spaces
	or commas:
+
These options control when the feature should be enabled
(defaults to 'never'):
+
--
`always`;;
	always show in columns
`never`;;
	never show in columns
`auto`;;
	show in columns if the output is to the terminal
--
+
These options control layout (defaults to 'column').  Setting any
of these implies 'always' if none of 'always', 'never', or 'auto' are
specified.
+
--
`column`;;
	fill columns before rows
`row`;;
	fill rows before columns
`plain`;;
	show in one column
--
+
Finally, these options can be combined with a layout option (defaults
to 'nodense'):
+
--
`dense`;;
	make unequal size columns to utilize more space
`nodense`;;
	make equal size columns
--

column.branch::
	Specify whether to output branch listing in `git branch` in columns.
	See `column.ui` for details.

column.clean::
	Specify the layout when listing items in `git clean -i`, which always
	shows files and directories in columns. See `column.ui` for details.

column.status::
	Specify whether to output untracked files in `git status` in columns.
	See `column.ui` for details.

column.tag::
	Specify whether to output tag listings in `git tag` in columns.
	See `column.ui` for details.

commit.cleanup::
	This setting overrides the default of the `--cleanup` option in
	`git commit`. See linkgit:git-commit[1] for details. Changing the
	default can be useful when you always want to keep lines that begin
	with the comment character `#` in your log message, in which case you
	would do `git config commit.cleanup whitespace` (note that you will
	have to remove the help lines that begin with `#` in the commit log
	template yourself, if you do this).

commit.gpgSign::

	A boolean to specify whether all commits should be GPG signed.
	Use of this option when doing operations such as rebase can
	result in a large number of commits being signed. It may be
	convenient to use an agent to avoid typing your GPG passphrase
	several times.

commit.status::
	A boolean to enable/disable inclusion of status information in the
	commit message template when using an editor to prepare the commit
	message.  Defaults to true.

commit.template::
	Specify the pathname of a file to use as the template for
	new commit messages.

commit.verbose::
	A boolean or int to specify the level of verbosity with `git commit`.
	See linkgit:git-commit[1].

commitGraph.generationVersion::
	Specifies the type of generation number version to use when writing
	or reading the commit-graph file. If version 1 is specified, then
	the corrected commit dates will not be written or read. Defaults to
	2.

commitGraph.maxNewFilters::
	Specifies the default value for the `--max-new-filters` option of `git
	commit-graph write` (c.f., linkgit:git-commit-graph[1]).

commitGraph.readChangedPaths::
	If true, then git will use the changed-path Bloom filters in the
	commit-graph file (if it exists, and they are present). Defaults to
	true. See linkgit:git-commit-graph[1] for more information.

completion.commands::
	This is only used by git-completion.bash to add or remove
	commands from the list of completed commands. Normally only
	porcelain commands and a few select others are completed. You
	can add more commands, separated by space, in this
	variable. Prefixing the command with '-' will remove it from
	the existing list.

core.fileMode::
	Tells Git if the executable bit of files in the working tree
	is to be honored.
+
Some filesystems lose the executable bit when a file that is
marked as executable is checked out, or checks out a
non-executable file with executable bit on.
linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
to see if it handles the executable bit correctly
and this variable is automatically set as necessary.
+
A repository, however, may be on a filesystem that handles
the filemode correctly, and this variable is set to 'true'
when created, but later may be made accessible from another
environment that loses the filemode (e.g. exporting ext4 via
CIFS mount, visiting a Cygwin created repository with
Git for Windows or Eclipse).
In such a case it may be necessary to set this variable to 'false'.
See linkgit:git-update-index[1].
+
The default is true (when core.filemode is not specified in the config file).

core.hideDotFiles::
	(Windows-only) If true, mark newly-created directories and files whose
	name starts with a dot as hidden.  If 'dotGitOnly', only the `.git/`
	directory is hidden, but no other files starting with a dot.  The
	default mode is 'dotGitOnly'.

core.ignoreCase::
	Internal variable which enables various workarounds to enable
	Git to work better on filesystems that are not case sensitive,
	like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing
	finds "makefile" when Git expects "Makefile", Git will assume
	it is really the same file, and continue to remember it as
	"Makefile".
+
The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
will probe and set core.ignoreCase true if appropriate when the repository
is created.
+
Git relies on the proper configuration of this variable for your operating
and file system. Modifying this value may result in unexpected behavior.

core.precomposeUnicode::
	This option is only used by Mac OS implementation of Git.
	When core.precomposeUnicode=true, Git reverts the unicode decomposition
	of filenames done by Mac OS. This is useful when sharing a repository
	between Mac OS and Linux or Windows.
	(Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
	When false, file names are handled fully transparent by Git,
	which is backward compatible with older versions of Git.

core.protectHFS::
	If set to true, do not allow checkout of paths that would
	be considered equivalent to `.git` on an HFS+ filesystem.
	Defaults to `true` on Mac OS, and `false` elsewhere.

core.protectNTFS::
	If set to true, do not allow checkout of paths that would
	cause problems with the NTFS filesystem, e.g. conflict with
	8.3 "short" names.
	Defaults to `true` on Windows, and `false` elsewhere.

core.fsmonitor::
	If set to true, enable the built-in file system monitor
	daemon for this working directory (linkgit:git-fsmonitor{litdd}daemon[1]).
+
Like hook-based file system monitors, the built-in file system monitor
can speed up Git commands that need to refresh the Git index
(e.g. `git status`) in a working directory with many files.  The
built-in monitor eliminates the need to install and maintain an
external third-party tool.
+
The built-in file system monitor is currently available only on a
limited set of supported platforms.  Currently, this includes Windows
and MacOS.
+
	Otherwise, this variable contains the pathname of the "fsmonitor"
	hook command.
+
This hook command is used to identify all files that may have changed
since the requested date/time. This information is used to speed up
git by avoiding unnecessary scanning of files that have not changed.
+
See the "fsmonitor-watchman" section of linkgit:githooks[5].
+
Note that if you concurrently use multiple versions of Git, such
as one version on the command line and another version in an IDE
tool, that the definition of `core.fsmonitor` was extended to
allow boolean values in addition to hook pathnames.  Git versions
2.35.1 and prior will not understand the boolean values and will
consider the "true" or "false" values as hook pathnames to be
invoked.  Git versions 2.26 thru 2.35.1 default to hook protocol
V2 and will fall back to no fsmonitor (full scan).  Git versions
prior to 2.26 default to hook protocol V1 and will silently
assume there were no changes to report (no scan), so status
commands may report incomplete results.  For this reason, it is
best to upgrade all of your Git versions before using the built-in
file system monitor.

core.fsmonitorHookVersion::
	Sets the protocol version to be used when invoking the
	"fsmonitor" hook.
+
There are currently versions 1 and 2. When this is not set,
version 2 will be tried first and if it fails then version 1
will be tried. Version 1 uses a timestamp as input to determine
which files have changes since that time but some monitors
like Watchman have race conditions when used with a timestamp.
Version 2 uses an opaque string so that the monitor can return
something that can be used to determine what files have changed
without race conditions.

core.trustctime::
	If false, the ctime differences between the index and the
	working tree are ignored; useful when the inode change time
	is regularly modified by something outside Git (file system
	crawlers and some backup systems).
	See linkgit:git-update-index[1]. True by default.

core.splitIndex::
	If true, the split-index feature of the index will be used.
	See linkgit:git-update-index[1]. False by default.

core.untrackedCache::
	Determines what to do about the untracked cache feature of the
	index. It will be kept, if this variable is unset or set to
	`keep`. It will automatically be added if set to `true`. And
	it will automatically be removed, if set to `false`. Before
	setting it to `true`, you should check that mtime is working
	properly on your system.
	See linkgit:git-update-index[1]. `keep` by default, unless
	`feature.manyFiles` is enabled which sets this setting to
	`true` by default.

core.checkStat::
	When missing or is set to `default`, many fields in the stat
	structure are checked to detect if a file has been modified
	since Git looked at it.  When this configuration variable is
	set to `minimal`, sub-second part of mtime and ctime, the
	uid and gid of the owner of the file, the inode number (and
	the device number, if Git was compiled to use it), are
	excluded from the check among these fields, leaving only the
	whole-second part of mtime (and ctime, if `core.trustCtime`
	is set) and the filesize to be checked.
+
There are implementations of Git that do not leave usable values in
some fields (e.g. JGit); by excluding these fields from the
comparison, the `minimal` mode may help interoperability when the
same repository is used by these other systems at the same time.

core.quotePath::
	Commands that output paths (e.g. 'ls-files', 'diff'), will
	quote "unusual" characters in the pathname by enclosing the
	pathname in double-quotes and escaping those characters with
	backslashes in the same way C escapes control characters (e.g.
	`\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with
	values larger than 0x80 (e.g. octal `\302\265` for "micro" in
	UTF-8).  If this variable is set to false, bytes higher than
	0x80 are not considered "unusual" any more. Double-quotes,
	backslash and control characters are always escaped regardless
	of the setting of this variable.  A simple space character is
	not considered "unusual".  Many commands can output pathnames
	completely verbatim using the `-z` option. The default value
	is true.

core.eol::
	Sets the line ending type to use in the working directory for
	files that are marked as text (either by having the `text`
	attribute set, or by having `text=auto` and Git auto-detecting
	the contents as text).
	Alternatives are 'lf', 'crlf' and 'native', which uses the platform's
	native line ending.  The default value is `native`.  See
	linkgit:gitattributes[5] for more information on end-of-line
	conversion. Note that this value is ignored if `core.autocrlf`
	is set to `true` or `input`.

core.safecrlf::
	If true, makes Git check if converting `CRLF` is reversible when
	end-of-line conversion is active.  Git will verify if a command
	modifies a file in the work tree either directly or indirectly.
	For example, committing a file followed by checking out the
	same file should yield the original file in the work tree.  If
	this is not the case for the current setting of
	`core.autocrlf`, Git will reject the file.  The variable can
	be set to "warn", in which case Git will only warn about an
	irreversible conversion but continue the operation.
+
CRLF conversion bears a slight chance of corrupting data.
When it is enabled, Git will convert CRLF to LF during commit and LF to
CRLF during checkout.  A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by Git.  For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.
+
If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes.  Right
after committing you still have the original file in your work
tree and this file is not yet corrupted.  You can explicitly tell
Git that this file is binary and Git will handle the file
appropriately.
+
Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished.  In both cases CRLFs are removed
in an irreversible way.  For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.
+
Note, this safety check does not mean that a checkout will generate a
file identical to the original file for a different setting of
`core.eol` and `core.autocrlf`, but only for the current one.  For
example, a text file with `LF` would be accepted with `core.eol=lf`
and could later be checked out with `core.eol=crlf`, in which case the
resulting file would contain `CRLF`, although the original file
contained `LF`.  However, in both work trees the line endings would be
consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
file with mixed line endings would be reported by the `core.safecrlf`
mechanism.

core.autocrlf::
	Setting this variable to "true" is the same as setting
	the `text` attribute to "auto" on all files and core.eol to "crlf".
	Set to true if you want to have `CRLF` line endings in your
	working directory and the repository has LF line endings.
	This variable can be set to 'input',
	in which case no output conversion is performed.

core.checkRoundtripEncoding::
	A comma and/or whitespace separated list of encodings that Git
	performs UTF-8 round trip checks on if they are used in an
	`working-tree-encoding` attribute (see linkgit:gitattributes[5]).
	The default value is `SHIFT-JIS`.

core.symlinks::
	If false, symbolic links are checked out as small plain files that
	contain the link text. linkgit:git-update-index[1] and
	linkgit:git-add[1] will not change the recorded type to regular
	file. Useful on filesystems like FAT that do not support
	symbolic links.
+
The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
will probe and set core.symlinks false if appropriate when the repository
is created.

core.gitProxy::
	A "proxy command" to execute (as 'command host port') instead
	of establishing direct connection to the remote server when
	using the Git protocol for fetching. If the variable value is
	in the "COMMAND for DOMAIN" format, the command is applied only
	on hostnames ending with the specified domain string. This variable
	may be set multiple times and is matched in the given order;
	the first match wins.
+
Can be overridden by the `GIT_PROXY_COMMAND` environment variable
(which always applies universally, without the special "for"
handling).
+
The special string `none` can be used as the proxy command to
specify that no proxy be used for a given domain pattern.
This is useful for excluding servers inside a firewall from
proxy use, while defaulting to a common proxy for external domains.

core.sshCommand::
	If this variable is set, `git fetch` and `git push` will
	use the specified command instead of `ssh` when they need to
	connect to a remote system. The command is in the same form as
	the `GIT_SSH_COMMAND` environment variable and is overridden
	when the environment variable is set.

core.ignoreStat::
	If true, Git will avoid using lstat() calls to detect if files have
	changed by setting the "assume-unchanged" bit for those tracked files
	which it has updated identically in both the index and working tree.
+
When files are modified outside of Git, the user will need to stage
the modified files explicitly (e.g. see 'Examples' section in
linkgit:git-update-index[1]).
Git will not normally detect changes to those files.
+
This is useful on systems where lstat() calls are very slow, such as
CIFS/Microsoft Windows.
+
False by default.

core.preferSymlinkRefs::
	Instead of the default "symref" format for HEAD
	and other symbolic reference files, use symbolic links.
	This is sometimes needed to work with old scripts that
	expect HEAD to be a symbolic link.

core.alternateRefsCommand::
	When advertising tips of available history from an alternate, use the shell to
	execute the specified command instead of linkgit:git-for-each-ref[1]. The
	first argument is the absolute path of the alternate. Output must contain one
	hex object id per line (i.e., the same as produced by `git for-each-ref
	--format='%(objectname)'`).
+
Note that you cannot generally put `git for-each-ref` directly into the config
value, as it does not take a repository path as an argument (but you can wrap
the command above in a shell script).

core.alternateRefsPrefixes::
	When listing references from an alternate, list only references that begin
	with the given prefix. Prefixes match as if they were given as arguments to
	linkgit:git-for-each-ref[1]. To list multiple prefixes, separate them with
	whitespace. If `core.alternateRefsCommand` is set, setting
	`core.alternateRefsPrefixes` has no effect.

core.bare::
	If true this repository is assumed to be 'bare' and has no
	working directory associated with it.  If this is the case a
	number of commands that require a working directory will be
	disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
+
This setting is automatically guessed by linkgit:git-clone[1] or
linkgit:git-init[1] when the repository was created.  By default a
repository that ends in "/.git" is assumed to be not bare (bare =
false), while all other repositories are assumed to be bare (bare
= true).

core.worktree::
	Set the path to the root of the working tree.
	If `GIT_COMMON_DIR` environment variable is set, core.worktree
	is ignored and not used for determining the root of working tree.
	This can be overridden by the `GIT_WORK_TREE` environment
	variable and the `--work-tree` command-line option.
	The value can be an absolute path or relative to the path to
	the .git directory, which is either specified by --git-dir
	or GIT_DIR, or automatically discovered.
	If --git-dir or GIT_DIR is specified but none of
	--work-tree, GIT_WORK_TREE and core.worktree is specified,
	the current working directory is regarded as the top level
	of your working tree.
+
Note that this variable is honored even when set in a configuration
file in a ".git" subdirectory of a directory and its value differs
from the latter directory (e.g. "/path/to/.git/config" has
core.worktree set to "/different/path"), which is most likely a
misconfiguration.  Running Git commands in the "/path/to" directory will
still use "/different/path" as the root of the work tree and can cause
confusion unless you know what you are doing (e.g. you are creating a
read-only snapshot of the same index to a location different from the
repository's usual working tree).

core.logAllRefUpdates::
	Enable the reflog. Updates to a ref <ref> is logged to the file
	"`$GIT_DIR/logs/<ref>`", by appending the new and old
	SHA-1, the date/time and the reason of the update, but
	only when the file exists.  If this configuration
	variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`"
	file is automatically created for branch heads (i.e. under
	`refs/heads/`), remote refs (i.e. under `refs/remotes/`),
	note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`.
	If it is set to `always`, then a missing reflog is automatically
	created for any ref under `refs/`.
+
This information can be used to determine what commit
was the tip of a branch "2 days ago".
+
This value is true by default in a repository that has
a working directory associated with it, and false by
default in a bare repository.

core.repositoryFormatVersion::
	Internal variable identifying the repository format and layout
	version.

core.sharedRepository::
	When 'group' (or 'true'), the repository is made shareable between
	several users in a group (making sure all the files and objects are
	group-writable). When 'all' (or 'world' or 'everybody'), the
	repository will be readable by all users, additionally to being
	group-shareable. When 'umask' (or 'false'), Git will use permissions
	reported by umask(2). When '0xxx', where '0xxx' is an octal number,
	files in the repository will have this mode value. '0xxx' will override
	user's umask value (whereas the other options will only override
	requested parts of the user's umask value). Examples: '0660' will make
	the repo read/write-able for the owner and group, but inaccessible to
	others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
	repository that is group-readable but not group-writable.
	See linkgit:git-init[1]. False by default.

core.warnAmbiguousRefs::
	If true, Git will warn you if the ref name you passed it is ambiguous
	and might match multiple refs in the repository. True by default.

core.compression::
	An integer -1..9, indicating a default compression level.
	-1 is the zlib default. 0 means no compression,
	and 1..9 are various speed/size tradeoffs, 9 being slowest.
	If set, this provides a default to other compression variables,
	such as `core.looseCompression` and `pack.compression`.

core.looseCompression::
	An integer -1..9, indicating the compression level for objects that
	are not in a pack file. -1 is the zlib default. 0 means no
	compression, and 1..9 are various speed/size tradeoffs, 9 being
	slowest.  If not set,  defaults to core.compression.  If that is
	not set,  defaults to 1 (best speed).

core.packedGitWindowSize::
	Number of bytes of a pack file to map into memory in a
	single mapping operation.  Larger window sizes may allow
	your system to process a smaller number of large pack files
	more quickly.  Smaller window sizes will negatively affect
	performance due to increased calls to the operating system's
	memory manager, but may improve performance when accessing
	a large number of large pack files.
+
Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
be reasonable for all users/operating systems.  You probably do
not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.packedGitLimit::
	Maximum number of bytes to map simultaneously into memory
	from pack files.  If Git needs to access more than this many
	bytes at once to complete an operation it will unmap existing
	regions to reclaim virtual address space within the process.
+
Default is 256 MiB on 32 bit platforms and 32 TiB (effectively
unlimited) on 64 bit platforms.
This should be reasonable for all users/operating systems, except on
the largest projects.  You probably do not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.deltaBaseCacheLimit::
	Maximum number of bytes per thread to reserve for caching base objects
	that may be referenced by multiple deltified objects.  By storing the
	entire decompressed base objects in a cache Git is able
	to avoid unpacking and decompressing frequently used base
	objects multiple times.
+
Default is 96 MiB on all platforms.  This should be reasonable
for all users/operating systems, except on the largest projects.
You probably do not need to adjust this value.
+
Common unit suffixes of 'k', 'm', or 'g' are supported.

core.bigFileThreshold::
	The size of files considered "big", which as discussed below
	changes the behavior of numerous git commands, as well as how
	such files are stored within the repository. The default is
	512 MiB. Common unit suffixes of 'k', 'm', or 'g' are
	supported.
+
Files above the configured limit will be:
+
* Stored deflated in packfiles, without attempting delta compression.
+
The default limit is primarily set with this use-case in mind. With it,
most projects will have their source code and other text files delta
compressed, but not larger binary media files.
+
Storing large files without delta compression avoids excessive memory
usage, at the slight expense of increased disk usage.
+
* Will be treated as if they were labeled "binary" (see
  linkgit:gitattributes[5]). e.g. linkgit:git-log[1] and
  linkgit:git-diff[1] will not compute diffs for files above this limit.
+
* Will generally be streamed when written, which avoids excessive
memory usage, at the cost of some fixed overhead. Commands that make
use of this include linkgit:git-archive[1],
linkgit:git-fast-import[1], linkgit:git-index-pack[1],
linkgit:git-unpack-objects[1] and linkgit:git-fsck[1].

core.excludesFile::
	Specifies the pathname to the file that contains patterns to
	describe paths that are not meant to be tracked, in addition
	to `.gitignore` (per-directory) and `.git/info/exclude`.
	Defaults to `$XDG_CONFIG_HOME/git/ignore`.
	If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore`
	is used instead. See linkgit:gitignore[5].

core.askPass::
	Some commands (e.g. svn and http interfaces) that interactively
	ask for a password can be told to use an external program given
	via the value of this variable. Can be overridden by the `GIT_ASKPASS`
	environment variable. If not set, fall back to the value of the
	`SSH_ASKPASS` environment variable or, failing that, a simple password
	prompt. The external program shall be given a suitable prompt as
	command-line argument and write the password on its STDOUT.

core.attributesFile::
	In addition to `.gitattributes` (per-directory) and
	`.git/info/attributes`, Git looks into this file for attributes
	(see linkgit:gitattributes[5]). Path expansions are made the same
	way as for `core.excludesFile`. Its default value is
	`$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not
	set or empty, `$HOME/.config/git/attributes` is used instead.

core.hooksPath::
	By default Git will look for your hooks in the
	`$GIT_DIR/hooks` directory. Set this to different path,
	e.g. `/etc/git/hooks`, and Git will try to find your hooks in
	that directory, e.g. `/etc/git/hooks/pre-receive` instead of
	in `$GIT_DIR/hooks/pre-receive`.
+
The path can be either absolute or relative. A relative path is
taken as relative to the directory where the hooks are run (see
the "DESCRIPTION" section of linkgit:githooks[5]).
+
This configuration variable is useful in cases where you'd like to
centrally configure your Git hooks instead of configuring them on a
per-repository basis, or as a more flexible and centralized
alternative to having an `init.templateDir` where you've changed
default hooks.

core.editor::
	Commands such as `commit` and `tag` that let you edit
	messages by launching an editor use the value of this
	variable when it is set, and the environment variable
	`GIT_EDITOR` is not set.  See linkgit:git-var[1].

core.commentChar::
core.commentString::
	Commands such as `commit` and `tag` that let you edit
	messages consider a line that begins with this character
	commented, and removes them after the editor returns
	(default '#').
+
If set to "auto", `git-commit` would select a character that is not
the beginning character of any line in existing commit messages.
+
Note that these two variables are aliases of each other, and in modern
versions of Git you are free to use a string (e.g., `//` or `⁑⁕⁑`) with
`commentChar`. Versions of Git prior to v2.45.0 will ignore
`commentString` but will reject a value of `commentChar` that consists
of more than a single ASCII byte. If you plan to use your config with
older and newer versions of Git, you may want to specify both:
+
    [core]
    # single character for older versions
    commentChar = "#"
    # string for newer versions (which will override commentChar
    # because it comes later in the file)
    commentString = "//"

core.filesRefLockTimeout::
	The length of time, in milliseconds, to retry when trying to
	lock an individual reference. Value 0 means not to retry at
	all; -1 means to try indefinitely. Default is 100 (i.e.,
	retry for 100ms).

core.packedRefsTimeout::
	The length of time, in milliseconds, to retry when trying to
	lock the `packed-refs` file. Value 0 means not to retry at
	all; -1 means to try indefinitely. Default is 1000 (i.e.,
	retry for 1 second).

core.pager::
	Text viewer for use by Git commands (e.g., 'less').  The value
	is meant to be interpreted by the shell.  The order of preference
	is the `$GIT_PAGER` environment variable, then `core.pager`
	configuration, then `$PAGER`, and then the default chosen at
	compile time (usually 'less').
+
When the `LESS` environment variable is unset, Git sets it to `FRX`
(if `LESS` environment variable is set, Git does not change it at
all).  If you want to selectively override Git's default setting
for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
be passed to the shell by Git, which will translate the final
command to `LESS=FRX less -S`. The environment does not set the
`S` option but the command line does, instructing less to truncate
long lines. Similarly, setting `core.pager` to `less -+F` will
deactivate the `F` option specified by the environment from the
command-line, deactivating the "quit if one screen" behavior of
`less`.  One can specifically activate some flags for particular
commands: for example, setting `pager.blame` to `less -S` enables
line truncation only for `git blame`.
+
Likewise, when the `LV` environment variable is unset, Git sets it
to `-c`.  You can override this setting by exporting `LV` with
another value or setting `core.pager` to `lv +c`.

core.whitespace::
	A comma separated list of common whitespace problems to
	notice.  'git diff' will use `color.diff.whitespace` to
	highlight them, and 'git apply --whitespace=error' will
	consider them as errors.  You can prefix `-` to disable
	any of them (e.g. `-trailing-space`):
+
* `blank-at-eol` treats trailing whitespaces at the end of the line
  as an error (enabled by default).
* `space-before-tab` treats a space character that appears immediately
  before a tab character in the initial indent part of the line as an
  error (enabled by default).
* `indent-with-non-tab` treats a line that is indented with space
  characters instead of the equivalent tabs as an error (not enabled by
  default).
* `tab-in-indent` treats a tab character in the initial indent part of
  the line as an error (not enabled by default).
* `blank-at-eof` treats blank lines added at the end of file as an error
  (enabled by default).
* `trailing-space` is a short-hand to cover both `blank-at-eol` and
  `blank-at-eof`.
* `cr-at-eol` treats a carriage-return at the end of line as
  part of the line terminator, i.e. with it, `trailing-space`
  does not trigger if the character before such a carriage-return
  is not a whitespace (not enabled by default).
* `tabwidth=<n>` tells how many character positions a tab occupies; this
  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
  errors. The default tab width is 8. Allowed values are 1 to 63.

core.fsync::
	A comma-separated list of components of the repository that
	should be hardened via the core.fsyncMethod when created or
	modified.  You can disable hardening of any component by
	prefixing it with a '-'.  Items that are not hardened may be
	lost in the event of an unclean	system shutdown. Unless you
	have special requirements, it is recommended that you leave
	this option empty or pick one of `committed`, `added`,
	or `all`.
+
When this configuration is encountered, the set of components starts with
the platform default value, disabled components are removed, and additional
components are added. `none` resets the state so that the platform default
is ignored.
+
The empty string resets the fsync configuration to the platform
default. The default on most platforms is equivalent to
`core.fsync=committed,-loose-object`, which has good performance,
but risks losing recent work in the event of an unclean system shutdown.
+
* `none` clears the set of fsynced components.
* `loose-object` hardens objects added to the repo in loose-object form.
* `pack` hardens objects added to the repo in packfile form.
* `pack-metadata` hardens packfile bitmaps and indexes.
* `commit-graph` hardens the commit-graph file.
* `index` hardens the index when it is modified.
* `objects` is an aggregate option that is equivalent to
  `loose-object,pack`.
* `reference` hardens references modified in the repo.
* `derived-metadata` is an aggregate option that is equivalent to
  `pack-metadata,commit-graph`.
* `committed` is an aggregate option that is currently equivalent to
  `objects`. This mode sacrifices some performance to ensure that work
  that is committed to the repository with `git commit` or similar commands
  is hardened.
* `added` is an aggregate option that is currently equivalent to
  `committed,index`. This mode sacrifices additional performance to
  ensure that the results of commands like `git add` and similar operations
  are hardened.
* `all` is an aggregate option that syncs all individual components above.

core.fsyncMethod::
	A value indicating the strategy Git will use to harden repository data
	using fsync and related primitives.
+
* `fsync` uses the fsync() system call or platform equivalents.
* `writeout-only` issues pagecache writeback requests, but depending on the
  filesystem and storage hardware, data added to the repository may not be
  durable in the event of a system crash. This is the default mode on macOS.
* `batch` enables a mode that uses writeout-only flushes to stage multiple
  updates in the disk writeback cache and then does a single full fsync of
  a dummy file to trigger the disk cache flush at the end of the operation.
+
Currently `batch` mode only applies to loose-object files. Other repository
data is made durable as if `fsync` was specified. This mode is expected to
be as safe as `fsync` on macOS for repos stored on HFS+ or APFS filesystems
and on Windows for repos stored on NTFS or ReFS filesystems.

core.fsyncObjectFiles::
	This boolean will enable 'fsync()' when writing object files.
	This setting is deprecated. Use core.fsync instead.
+
This setting affects data added to the Git repository in loose-object
form. When set to true, Git will issue an fsync or similar system call
to flush caches so that loose-objects remain consistent in the face
of a unclean system shutdown.

core.preloadIndex::
	Enable parallel index preload for operations like 'git diff'
+
This can speed up operations like 'git diff' and 'git status' especially
on filesystems like NFS that have weak caching semantics and thus
relatively high IO latencies.  When enabled, Git will do the
index comparison to the filesystem data in parallel, allowing
overlapping IO's.  Defaults to true.

core.unsetenvvars::
	Windows-only: comma-separated list of environment variables'
	names that need to be unset before spawning any other process.
	Defaults to `PERL5LIB` to account for the fact that Git for
	Windows insists on using its own Perl interpreter.

core.restrictinheritedhandles::
	Windows-only: override whether spawned processes inherit only standard
	file handles (`stdin`, `stdout` and `stderr`) or all handles. Can be
	`auto`, `true` or `false`. Defaults to `auto`, which means `true` on
	Windows 7 and later, and `false` on older Windows versions.

core.createObject::
	You can set this to 'link', in which case a hardlink followed by
	a delete of the source are used to make sure that object creation
	will not overwrite existing objects.
+
On some file system/operating system combinations, this is unreliable.
Set this config setting to 'rename' there; however, this will remove the
check that makes sure that existing object files will not get overwritten.

core.notesRef::
	When showing commit messages, also show notes which are stored in
	the given ref.  The ref must be fully qualified.  If the given
	ref does not exist, it is not an error but means that no
	notes should be printed.
+
This setting defaults to "refs/notes/commits", and it can be overridden by
the `GIT_NOTES_REF` environment variable.  See linkgit:git-notes[1].

core.commitGraph::
	If true, then git will read the commit-graph file (if it exists)
	to parse the graph structure of commits. Defaults to true. See
	linkgit:git-commit-graph[1] for more information.

core.useReplaceRefs::
	If set to `false`, behave as if the `--no-replace-objects`
	option was given on the command line. See linkgit:git[1] and
	linkgit:git-replace[1] for more information.

core.multiPackIndex::
	Use the multi-pack-index file to track multiple packfiles using a
	single index. See linkgit:git-multi-pack-index[1] for more
	information. Defaults to true.

core.sparseCheckout::
	Enable "sparse checkout" feature. See linkgit:git-sparse-checkout[1]
	for more information.

core.sparseCheckoutCone::
	Enables the "cone mode" of the sparse checkout feature. When the
	sparse-checkout file contains a limited set of patterns, this
	mode provides significant performance advantages. The "non-cone
	mode" can be requested to allow specifying more flexible
	patterns by setting this variable to 'false'. See
	linkgit:git-sparse-checkout[1] for more information.

core.abbrev::
	Set the length object names are abbreviated to.  If
	unspecified or set to "auto", an appropriate value is
	computed based on the approximate number of packed objects
	in your repository, which hopefully is enough for
	abbreviated object names to stay unique for some time.
	If set to "no", no abbreviation is made and the object names
	are shown in their full length.
	The minimum length is 4.

core.maxTreeDepth::
	The maximum depth Git is willing to recurse while traversing a
	tree (e.g., "a/b/cde/f" has a depth of 4). This is a fail-safe
	to allow Git to abort cleanly, and should not generally need to
	be adjusted. The default is 4096.

credential.helper::
	Specify an external helper to be called when a username or
	password credential is needed; the helper may consult external
	storage to avoid prompting the user for the credentials. This is
	normally the name of a credential helper with possible
	arguments, but may also be an absolute path with arguments or, if
	preceded by `!`, shell commands.
+
Note that multiple helpers may be defined. See linkgit:gitcredentials[7]
for details and examples.

credential.useHttpPath::
	When acquiring credentials, consider the "path" component of an http
	or https URL to be important. Defaults to false. See
	linkgit:gitcredentials[7] for more information.

credential.username::
	If no username is set for a network authentication, use this username
	by default. See credential.<context>.* below, and
	linkgit:gitcredentials[7].

credential.<url>.*::
	Any of the credential.* options above can be applied selectively to
	some credentials. For example, "credential.https://example.com.username"
	would set the default username only for https connections to
	example.com. See linkgit:gitcredentials[7] for details on how URLs are
	matched.

credentialCache.ignoreSIGHUP::
	Tell git-credential-cache--daemon to ignore SIGHUP, instead of quitting.

credentialStore.lockTimeoutMS::
	The length of time, in milliseconds, for git-credential-store to retry
	when trying to lock the credentials file. A value of 0 means not to retry at
	all; -1 means to try indefinitely. Default is 1000 (i.e., retry for
	1s).

diff.autoRefreshIndex::
	When using 'git diff' to compare with work tree
	files, do not consider stat-only changes as changed.
	Instead, silently run `git update-index --refresh` to
	update the cached stat information for paths whose
	contents in the work tree match the contents in the
	index.  This option defaults to true.  Note that this
	affects only 'git diff' Porcelain, and not lower level
	'diff' commands such as 'git diff-files'.

diff.dirstat::
	A comma separated list of `--dirstat` parameters specifying the
	default behavior of the `--dirstat` option to linkgit:git-diff[1]
	and friends. The defaults can be overridden on the command line
	(using `--dirstat=<param1,param2,...>`). The fallback defaults
	(when not changed by `diff.dirstat`) are `changes,noncumulative,3`.
	The following parameters are available:
+
--
`changes`;;
	Compute the dirstat numbers by counting the lines that have been
	removed from the source, or added to the destination. This ignores
	the amount of pure code movements within a file.  In other words,
	rearranging lines in a file is not counted as much as other changes.
	This is the default behavior when no parameter is given.
`lines`;;
	Compute the dirstat numbers by doing the regular line-based diff
	analysis, and summing the removed/added line counts. (For binary
	files, count 64-byte chunks instead, since binary files have no
	natural concept of lines). This is a more expensive `--dirstat`
	behavior than the `changes` behavior, but it does count rearranged
	lines within a file as much as other changes. The resulting output
	is consistent with what you get from the other `--*stat` options.
`files`;;
	Compute the dirstat numbers by counting the number of files changed.
	Each changed file counts equally in the dirstat analysis. This is
	the computationally cheapest `--dirstat` behavior, since it does
	not have to look at the file contents at all.
`cumulative`;;
	Count changes in a child directory for the parent directory as well.
	Note that when using `cumulative`, the sum of the percentages
	reported may exceed 100%. The default (non-cumulative) behavior can
	be specified with the `noncumulative` parameter.
<limit>;;
	An integer parameter specifies a cut-off percent (3% by default).
	Directories contributing less than this percentage of the changes
	are not shown in the output.
--
+
Example: The following will count changed files, while ignoring
directories with less than 10% of the total amount of changed files,
and accumulating child directory counts in the parent directories:
`files,10,cumulative`.

diff.statNameWidth::
	Limit the width of the filename part in --stat output. If set, applies
	to all commands generating --stat output except format-patch.

diff.statGraphWidth::
	Limit the width of the graph part in --stat output. If set, applies
	to all commands generating --stat output except format-patch.

diff.context::
	Generate diffs with <n> lines of context instead of the default
	of 3. This value is overridden by the -U option.

diff.interHunkContext::
	Show the context between diff hunks, up to the specified number
	of lines, thereby fusing the hunks that are close to each other.
	This value serves as the default for the `--inter-hunk-context`
	command line option.

diff.external::
	If this config variable is set, diff generation is not
	performed using the internal diff machinery, but using the
	given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
	environment variable.  The command is called with parameters
	as described under "git Diffs" in linkgit:git[1].  Note: if
	you want to use an external diff program only on a subset of
	your files, you might want to use linkgit:gitattributes[5] instead.

diff.ignoreSubmodules::
	Sets the default value of --ignore-submodules. Note that this
	affects only 'git diff' Porcelain, and not lower level 'diff'
	commands such as 'git diff-files'. 'git checkout'
	and 'git switch' also honor
	this setting when reporting uncommitted changes. Setting it to
	'all' disables the submodule summary normally shown by 'git commit'
	and 'git status' when `status.submoduleSummary` is set unless it is
	overridden by using the --ignore-submodules command-line option.
	The 'git submodule' commands are not affected by this setting.
	By default this is set to untracked so that any untracked
	submodules are ignored.

diff.mnemonicPrefix::
	If set, 'git diff' uses a prefix pair that is different from the
	standard "a/" and "b/" depending on what is being compared.  When
	this configuration is in effect, reverse diff output also swaps
	the order of the prefixes:
`git diff`;;
	compares the (i)ndex and the (w)ork tree;
`git diff HEAD`;;
	 compares a (c)ommit and the (w)ork tree;
`git diff --cached`;;
	compares a (c)ommit and the (i)ndex;
`git diff HEAD:file1 file2`;;
	compares an (o)bject and a (w)ork tree entity;
`git diff --no-index a b`;;
	compares two non-git things (1) and (2).

diff.noPrefix::
	If set, 'git diff' does not show any source or destination prefix.

diff.srcPrefix::
	If set, 'git diff' uses this source prefix. Defaults to "a/".

diff.dstPrefix::
	If set, 'git diff' uses this destination prefix. Defaults to "b/".

diff.relative::
	If set to 'true', 'git diff' does not show changes outside of the directory
	and show pathnames relative to the current directory.

diff.orderFile::
	File indicating how to order files within a diff.
	See the '-O' option to linkgit:git-diff[1] for details.
	If `diff.orderFile` is a relative pathname, it is treated as
	relative to the top of the working tree.

diff.renameLimit::
	The number of files to consider in the exhaustive portion of
	copy/rename detection; equivalent to the 'git diff' option
	`-l`.  If not set, the default value is currently 1000.  This
	setting has no effect if rename detection is turned off.

diff.renames::
	Whether and how Git detects renames.  If set to "false",
	rename detection is disabled. If set to "true", basic rename
	detection is enabled.  If set to "copies" or "copy", Git will
	detect copies, as well.  Defaults to true.  Note that this
	affects only 'git diff' Porcelain like linkgit:git-diff[1] and
	linkgit:git-log[1], and not lower level commands such as
	linkgit:git-diff-files[1].

diff.suppressBlankEmpty::
	A boolean to inhibit the standard behavior of printing a space
	before each empty output line. Defaults to false.

diff.submodule::
	Specify the format in which differences in submodules are
	shown.  The "short" format just shows the names of the commits
	at the beginning and end of the range. The "log" format lists
	the commits in the range like linkgit:git-submodule[1] `summary`
	does. The "diff" format shows an inline diff of the changed
	contents of the submodule. Defaults to "short".

diff.wordRegex::
	A POSIX Extended Regular Expression used to determine what is a "word"
	when performing word-by-word difference calculations.  Character
	sequences that match the regular expression are "words", all other
	characters are *ignorable* whitespace.

diff.<driver>.command::
	The custom diff driver command.  See linkgit:gitattributes[5]
	for details.

diff.<driver>.xfuncname::
	The regular expression that the diff driver should use to
	recognize the hunk header.  A built-in pattern may also be used.
	See linkgit:gitattributes[5] for details.

diff.<driver>.binary::
	Set this option to true to make the diff driver treat files as
	binary.  See linkgit:gitattributes[5] for details.

diff.<driver>.textconv::
	The command that the diff driver should call to generate the
	text-converted version of a file.  The result of the
	conversion is used to generate a human-readable diff.  See
	linkgit:gitattributes[5] for details.

diff.<driver>.wordRegex::
	The regular expression that the diff driver should use to
	split words in a line.  See linkgit:gitattributes[5] for
	details.

diff.<driver>.cachetextconv::
	Set this option to true to make the diff driver cache the text
	conversion outputs.  See linkgit:gitattributes[5] for details.

Unresolved directive in config/diff.txt - include::../mergetools-diff.txt[]

diff.indentHeuristic::
	Set this option to `false` to disable the default heuristics
	that shift diff hunk boundaries to make patches easier to read.

diff.algorithm::
	Choose a diff algorithm.  The variants are as follows:
+
--
`default`, `myers`;;
	The basic greedy diff algorithm. Currently, this is the default.
`minimal`;;
	Spend extra time to make sure the smallest possible diff is
	produced.
`patience`;;
	Use "patience diff" algorithm when generating patches.
`histogram`;;
	This algorithm extends the patience algorithm to "support
	low-occurrence common elements".
--
+

diff.wsErrorHighlight::
	Highlight whitespace errors in the `context`, `old` or `new`
	lines of the diff.  Multiple values are separated by comma,
	`none` resets previous values, `default` reset the list to
	`new` and `all` is a shorthand for `old,new,context`.  The
	whitespace errors are colored with `color.diff.whitespace`.
	The command line option `--ws-error-highlight=<kind>`
	overrides this setting.

diff.colorMoved::
	If set to either a valid `<mode>` or a true value, moved lines
	in a diff are colored differently, for details of valid modes
	see '--color-moved' in linkgit:git-diff[1]. If simply set to
	true the default color mode will be used. When set to false,
	moved lines are not colored.

diff.colorMovedWS::
	When moved lines are colored using e.g. the `diff.colorMoved` setting,
	this option controls the `<mode>` how spaces are treated.
	For details of valid modes see '--color-moved-ws' in linkgit:git-diff[1].

diff.tool::
	Controls which diff tool is used by linkgit:git-difftool[1].
	This variable overrides the value configured in `merge.tool`.
	The list below shows the valid built-in values.
	Any other value is treated as a custom diff tool and requires
	that a corresponding difftool.<tool>.cmd variable is defined.

diff.guitool::
	Controls which diff tool is used by linkgit:git-difftool[1] when
	the -g/--gui flag is specified. This variable overrides the value
	configured in `merge.guitool`. The list below shows the valid
	built-in values. Any other value is treated as a custom diff tool
	and requires that a corresponding difftool.<guitool>.cmd variable
	is defined.

difftool.<tool>.cmd::
	Specify the command to invoke the specified diff tool.
	The specified command is evaluated in shell with the following
	variables available:  'LOCAL' is set to the name of the temporary
	file containing the contents of the diff pre-image and 'REMOTE'
	is set to the name of the temporary file containing the contents
	of the diff post-image.
+
See the `--tool=<tool>` option in linkgit:git-difftool[1] for more details.

difftool.<tool>.path::
	Override the path for the given tool.  This is useful in case
	your tool is not in the PATH.

difftool.trustExitCode::
	Exit difftool if the invoked diff tool returns a non-zero exit status.
+
See the `--trust-exit-code` option in linkgit:git-difftool[1] for more details.

difftool.prompt::
	Prompt before each invocation of the diff tool.

difftool.guiDefault::
	Set `true` to use the `diff.guitool` by default (equivalent to specifying
	the `--gui` argument), or `auto` to select `diff.guitool` or `diff.tool`
	depending on the presence of a `DISPLAY` environment variable value. The
	default is `false`, where the `--gui` argument must be provided
	explicitly for the `diff.guitool` to be used.

extensions.objectFormat::
	Specify the hash algorithm to use.  The acceptable values are `sha1` and
	`sha256`.  If not specified, `sha1` is assumed.  It is an error to specify
	this key unless `core.repositoryFormatVersion` is 1.
+
Note that this setting should only be set by linkgit:git-init[1] or
linkgit:git-clone[1].  Trying to change it after initialization will not
work and will produce hard-to-diagnose issues.

extensions.compatObjectFormat::

	Specify a compatitbility hash algorithm to use.  The acceptable values
	are `sha1` and `sha256`.  The value specified must be different from the
	value of extensions.objectFormat.  This allows client level
	interoperability between git repositories whose objectFormat matches
	this compatObjectFormat.  In particular when fully implemented the
	pushes and pulls from a repository in whose objectFormat matches
	compatObjectFormat.  As well as being able to use oids encoded in
	compatObjectFormat in addition to oids encoded with objectFormat to
	locally specify objects.

extensions.refStorage::
	Specify the ref storage format to use. The acceptable values are:
+
* `files` for loose files with packed-refs. This is the default.
* `reftable` for the reftable format. This format is experimental and its
  internals are subject to change.
+
It is an error to specify this key unless `core.repositoryFormatVersion` is 1.
+
Note that this setting should only be set by linkgit:git-init[1] or
linkgit:git-clone[1]. Trying to change it after initialization will not
work and will produce hard-to-diagnose issues.

extensions.worktreeConfig::
	If enabled, then worktrees will load config settings from the
	`$GIT_DIR/config.worktree` file in addition to the
	`$GIT_COMMON_DIR/config` file. Note that `$GIT_COMMON_DIR` and
	`$GIT_DIR` are the same for the main working tree, while other
	working trees have `$GIT_DIR` equal to
	`$GIT_COMMON_DIR/worktrees/<id>/`. The settings in the
	`config.worktree` file will override settings from any other
	config files.
+
When enabling `extensions.worktreeConfig`, you must be careful to move
certain values from the common config file to the main working tree's
`config.worktree` file, if present:
+
* `core.worktree` must be moved from `$GIT_COMMON_DIR/config` to
  `$GIT_COMMON_DIR/config.worktree`.
* If `core.bare` is true, then it must be moved from `$GIT_COMMON_DIR/config`
  to `$GIT_COMMON_DIR/config.worktree`.
+
It may also be beneficial to adjust the locations of `core.sparseCheckout`
and `core.sparseCheckoutCone` depending on your desire for customizable
sparse-checkout settings for each worktree. By default, the `git
sparse-checkout` builtin enables `extensions.worktreeConfig`, assigns
these config values on a per-worktree basis, and uses the
`$GIT_DIR/info/sparse-checkout` file to specify the sparsity for each
worktree independently. See linkgit:git-sparse-checkout[1] for more
details.
+
For historical reasons, `extensions.worktreeConfig` is respected
regardless of the `core.repositoryFormatVersion` setting.

fastimport.unpackLimit::
	If the number of objects imported by linkgit:git-fast-import[1]
	is below this limit, then the objects will be unpacked into
	loose object files.  However, if the number of imported objects
	equals or exceeds this limit, then the pack will be stored as a
	pack.  Storing the pack from a fast-import can make the import
	operation complete faster, especially on slow filesystems.  If
	not set, the value of `transfer.unpackLimit` is used instead.

feature.*::
	The config settings that start with `feature.` modify the defaults of
	a group of other config settings. These groups are created by the Git
	developer community as recommended defaults and are subject to change.
	In particular, new config options may be added with different defaults.

feature.experimental::
	Enable config options that are new to Git, and are being considered for
	future defaults. Config settings included here may be added or removed
	with each release, including minor version updates. These settings may
	have unintended interactions since they are so new. Please enable this
	setting if you are interested in providing feedback on experimental
	features. The new default values are:
+
* `fetch.negotiationAlgorithm=skipping` may improve fetch negotiation times by
skipping more commits at a time, reducing the number of round trips.
+
* `pack.useBitmapBoundaryTraversal=true` may improve bitmap traversal times by
walking fewer objects.
+
* `pack.allowPackReuse=multi` may improve the time it takes to create a pack by
reusing objects from multiple packs instead of just one.

feature.manyFiles::
	Enable config options that optimize for repos with many files in the
	working directory. With many files, commands such as `git status` and
	`git checkout` may be slow and these new defaults improve performance:
+
* `index.skipHash=true` speeds up index writes by not computing a trailing
  checksum. Note that this will cause Git versions earlier than 2.13.0 to
  refuse to parse the index and Git versions earlier than 2.40.0 will report
  a corrupted index during `git fsck`.
+
* `index.version=4` enables path-prefix compression in the index.
+
* `core.untrackedCache=true` enables the untracked cache. This setting assumes
that mtime is working on your machine.

fetch.recurseSubmodules::
	This option controls whether `git fetch` (and the underlying fetch
	in `git pull`) will recursively fetch into populated submodules.
	This option can be set either to a boolean value or to 'on-demand'.
	Setting it to a boolean changes the behavior of fetch and pull to
	recurse unconditionally into submodules when set to true or to not
	recurse at all when set to false. When set to 'on-demand', fetch and
	pull will only recurse into a populated submodule when its
	superproject retrieves a commit that updates the submodule's
	reference.
	Defaults to 'on-demand', or to the value of 'submodule.recurse' if set.

fetch.fsckObjects::
	If it is set to true, git-fetch-pack will check all fetched
	objects. See `transfer.fsckObjects` for what's
	checked. Defaults to false. If not set, the value of
	`transfer.fsckObjects` is used instead.

fetch.fsck.<msg-id>::
	Acts like `fsck.<msg-id>`, but is used by
	linkgit:git-fetch-pack[1] instead of linkgit:git-fsck[1]. See
	the `fsck.<msg-id>` documentation for details.

fetch.fsck.skipList::
	Acts like `fsck.skipList`, but is used by
	linkgit:git-fetch-pack[1] instead of linkgit:git-fsck[1]. See
	the `fsck.skipList` documentation for details.

fetch.unpackLimit::
	If the number of objects fetched over the Git native
	transfer is below this
	limit, then the objects will be unpacked into loose object
	files. However if the number of received objects equals or
	exceeds this limit then the received pack will be stored as
	a pack, after adding any missing delta bases.  Storing the
	pack from a push can make the push operation complete faster,
	especially on slow filesystems.  If not set, the value of
	`transfer.unpackLimit` is used instead.

fetch.prune::
	If true, fetch will automatically behave as if the `--prune`
	option was given on the command line.  See also `remote.<name>.prune`
	and the PRUNING section of linkgit:git-fetch[1].

fetch.pruneTags::
	If true, fetch will automatically behave as if the
	`refs/tags/*:refs/tags/*` refspec was provided when pruning,
	if not set already. This allows for setting both this option
	and `fetch.prune` to maintain a 1=1 mapping to upstream
	refs. See also `remote.<name>.pruneTags` and the PRUNING
	section of linkgit:git-fetch[1].

fetch.all::
	If true, fetch will attempt to update all available remotes.
	This behavior can be overridden by passing `--no-all` or by
	explicitly specifying one or more remote(s) to fetch from.
	Defaults to false.

fetch.output::
	Control how ref update status is printed. Valid values are
	`full` and `compact`. Default value is `full`. See the
	OUTPUT section in linkgit:git-fetch[1] for details.

fetch.negotiationAlgorithm::
	Control how information about the commits in the local repository
	is sent when negotiating the contents of the packfile to be sent by
	the server.  Set to "consecutive" to use an algorithm that walks
	over consecutive commits checking each one.  Set to "skipping" to
	use an algorithm that skips commits in an effort to converge
	faster, but may result in a larger-than-necessary packfile; or set
	to "noop" to not send any information at all, which will almost
	certainly result in a larger-than-necessary packfile, but will skip
	the negotiation step.  Set to "default" to override settings made
	previously and use the default behaviour.  The default is normally
	"consecutive", but if `feature.experimental` is true, then the
	default is "skipping".  Unknown values will cause 'git fetch' to
	error out.
+
See also the `--negotiate-only` and `--negotiation-tip` options to
linkgit:git-fetch[1].

fetch.showForcedUpdates::
	Set to false to enable `--no-show-forced-updates` in
	linkgit:git-fetch[1] and linkgit:git-pull[1] commands.
	Defaults to true.

fetch.parallel::
	Specifies the maximal number of fetch operations to be run in parallel
	at a time (submodules, or remotes when the `--multiple` option of
	linkgit:git-fetch[1] is in effect).
+
A value of 0 will give some reasonable default. If unset, it defaults to 1.
+
For submodules, this setting can be overridden using the `submodule.fetchJobs`
config setting.

fetch.writeCommitGraph::
	Set to true to write a commit-graph after every `git fetch` command
	that downloads a pack-file from a remote. Using the `--split` option,
	most executions will create a very small commit-graph file on top of
	the existing commit-graph file(s). Occasionally, these files will
	merge and the write may take longer. Having an updated commit-graph
	file helps performance of many Git commands, including `git merge-base`,
	`git push -f`, and `git log --graph`. Defaults to false.

fetch.bundleURI::
	This value stores a URI for downloading Git object data from a bundle
	URI before performing an incremental fetch from the origin Git server.
	This is similar to how the `--bundle-uri` option behaves in
	linkgit:git-clone[1]. `git clone --bundle-uri` will set the
	`fetch.bundleURI` value if the supplied bundle URI contains a bundle
	list that is organized for incremental fetches.
+
If you modify this value and your repository has a `fetch.bundleCreationToken`
value, then remove that `fetch.bundleCreationToken` value before fetching from
the new bundle URI.

fetch.bundleCreationToken::
	When using `fetch.bundleURI` to fetch incrementally from a bundle
	list that uses the "creationToken" heuristic, this config value
	stores the maximum `creationToken` value of the downloaded bundles.
	This value is used to prevent downloading bundles in the future
	if the advertised `creationToken` is not strictly larger than this
	value.
+
The creation token values are chosen by the provider serving the specific
bundle URI. If you modify the URI at `fetch.bundleURI`, then be sure to
remove the value for the `fetch.bundleCreationToken` value before fetching.

filter.<driver>.clean::
	The command which is used to convert the content of a worktree
	file to a blob upon checkin.  See linkgit:gitattributes[5] for
	details.

filter.<driver>.smudge::
	The command which is used to convert the content of a blob
	object to a worktree file upon checkout.  See
	linkgit:gitattributes[5] for details.

format.attach::
	Enable multipart/mixed attachments as the default for
	'format-patch'.  The value can also be a double quoted string
	which will enable attachments as the default and set the
	value as the boundary.  See the --attach option in
	linkgit:git-format-patch[1].  To countermand an earlier
	value, set it to an empty string.

format.from::
	Provides the default value for the `--from` option to format-patch.
	Accepts a boolean value, or a name and email address.  If false,
	format-patch defaults to `--no-from`, using commit authors directly in
	the "From:" field of patch mails.  If true, format-patch defaults to
	`--from`, using your committer identity in the "From:" field of patch
	mails and including a "From:" field in the body of the patch mail if
	different.  If set to a non-boolean value, format-patch uses that
	value instead of your committer identity.  Defaults to false.

format.forceInBodyFrom::
	Provides the default value for the `--[no-]force-in-body-from`
	option to format-patch.  Defaults to false.

format.numbered::
	A boolean which can enable or disable sequence numbers in patch
	subjects.  It defaults to "auto" which enables it only if there
	is more than one patch.  It can be enabled or disabled for all
	messages by setting it to "true" or "false".  See --numbered
	option in linkgit:git-format-patch[1].

format.headers::
	Additional email headers to include in a patch to be submitted
	by mail.  See linkgit:git-format-patch[1].

format.to::
format.cc::
	Additional recipients to include in a patch to be submitted
	by mail.  See the --to and --cc options in
	linkgit:git-format-patch[1].

format.subjectPrefix::
	The default for format-patch is to output files with the '[PATCH]'
	subject prefix. Use this variable to change that prefix.

format.coverFromDescription::
	The default mode for format-patch to determine which parts of
	the cover letter will be populated using the branch's
	description. See the `--cover-from-description` option in
	linkgit:git-format-patch[1].

format.signature::
	The default for format-patch is to output a signature containing
	the Git version number. Use this variable to change that default.
	Set this variable to the empty string ("") to suppress
	signature generation.

format.signatureFile::
	Works just like format.signature except the contents of the
	file specified by this variable will be used as the signature.

format.suffix::
	The default for format-patch is to output files with the suffix
	`.patch`. Use this variable to change that suffix (make sure to
	include the dot if you want it).

format.encodeEmailHeaders::
	Encode email headers that have non-ASCII characters with
	"Q-encoding" (described in RFC 2047) for email transmission.
	Defaults to true.

format.pretty::
	The default pretty format for log/show/whatchanged command.
	See linkgit:git-log[1], linkgit:git-show[1],
	linkgit:git-whatchanged[1].

format.thread::
	The default threading style for 'git format-patch'.  Can be
	a boolean value, or `shallow` or `deep`.  `shallow` threading
	makes every mail a reply to the head of the series,
	where the head is chosen from the cover letter, the
	`--in-reply-to`, and the first patch mail, in this order.
	`deep` threading makes every mail a reply to the previous one.
	A true boolean value is the same as `shallow`, and a false
	value disables threading.

format.signOff::
	A boolean value which lets you enable the `-s/--signoff` option of
	format-patch by default. *Note:* Adding the `Signed-off-by` trailer to a
	patch should be a conscious act and means that you certify you have
	the rights to submit this work under the same open source license.
	Please see the 'SubmittingPatches' document for further discussion.

format.coverLetter::
	A boolean that controls whether to generate a cover-letter when
	format-patch is invoked, but in addition can be set to "auto", to
	generate a cover-letter only when there's more than one patch.
	Default is false.

format.outputDirectory::
	Set a custom directory to store the resulting files instead of the
	current working directory. All directory components will be created.

format.filenameMaxLength::
	The maximum length of the output filenames generated by the
	`format-patch` command; defaults to 64.  Can be overridden
	by the `--filename-max-length=<n>` command line option.

format.useAutoBase::
	A boolean value which lets you enable the `--base=auto` option of
	format-patch by default. Can also be set to "whenAble" to allow
	enabling `--base=auto` if a suitable base is available, but to skip
	adding base info otherwise without the format dying.

format.notes::
	Provides the default value for the `--notes` option to
	format-patch. Accepts a boolean value, or a ref which specifies
	where to get notes. If false, format-patch defaults to
	`--no-notes`. If true, format-patch defaults to `--notes`. If
	set to a non-boolean value, format-patch defaults to
	`--notes=<ref>`, where `ref` is the non-boolean value. Defaults
	to false.
+
If one wishes to use the ref `refs/notes/true`, please use that literal
instead.
+
This configuration can be specified multiple times in order to allow
multiple notes refs to be included. In that case, it will behave
similarly to multiple `--[no-]notes[=]` options passed in. That is, a
value of `true` will show the default notes, a value of `<ref>` will
also show notes from that notes ref and a value of `false` will negate
previous configurations and not show notes.
+
For example,
+
------------
[format]
	notes = true
	notes = foo
	notes = false
	notes = bar
------------
+
will only show notes from `refs/notes/bar`.

format.mboxrd::
	A boolean value which enables the robust "mboxrd" format when
	`--stdout` is in use to escape "^>+From " lines.

format.noprefix::
	If set, do not show any source or destination prefix in patches.
	This is equivalent to the `diff.noprefix` option used by `git
	diff` (but which is not respected by `format-patch`). Note that
	by setting this, the receiver of any patches you generate will
	have to apply them using the `-p0` option.

fsck.<msg-id>::
	During fsck git may find issues with legacy data which
	wouldn't be generated by current versions of git, and which
	wouldn't be sent over the wire if `transfer.fsckObjects` was
	set. This feature is intended to support working with legacy
	repositories containing such data.
+
Setting `fsck.<msg-id>` will be picked up by linkgit:git-fsck[1], but
to accept pushes of such data set `receive.fsck.<msg-id>` instead, or
to clone or fetch it set `fetch.fsck.<msg-id>`.
+
The rest of the documentation discusses `fsck.*` for brevity, but the
same applies for the corresponding `receive.fsck.*` and
`fetch.fsck.*`. variables.
+
Unlike variables like `color.ui` and `core.editor`, the
`receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>` variables will not
fall back on the `fsck.<msg-id>` configuration if they aren't set. To
uniformly configure the same fsck settings in different circumstances,
all three of them must be set to the same values.
+
When `fsck.<msg-id>` is set, errors can be switched to warnings and
vice versa by configuring the `fsck.<msg-id>` setting where the
`<msg-id>` is the fsck message ID and the value is one of `error`,
`warn` or `ignore`. For convenience, fsck prefixes the error/warning
with the message ID, e.g. "missingEmail: invalid author/committer
line - missing email" means that setting `fsck.missingEmail = ignore`
will hide that issue.
+
In general, it is better to enumerate existing objects with problems
with `fsck.skipList`, instead of listing the kind of breakages these
problematic objects share to be ignored, as doing the latter will
allow new instances of the same breakages go unnoticed.
+
Setting an unknown `fsck.<msg-id>` value will cause fsck to die, but
doing the same for `receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>`
will only cause git to warn.
+
See the `Fsck Messages` section of linkgit:git-fsck[1] for supported
values of `<msg-id>`.


fsck.skipList::
	The path to a list of object names (i.e. one unabbreviated SHA-1 per
	line) that are known to be broken in a non-fatal way and should
	be ignored. On versions of Git 2.20 and later, comments ('#'), empty
	lines, and any leading and trailing whitespace are ignored. Everything
	but a SHA-1 per line will error out on older versions.
+
This feature is useful when an established project should be accepted
despite early commits containing errors that can be safely ignored,
such as invalid committer email addresses.  Note: corrupt objects
cannot be skipped with this setting.
+
Like `fsck.<msg-id>` this variable has corresponding
`receive.fsck.skipList` and `fetch.fsck.skipList` variants.
+
Unlike variables like `color.ui` and `core.editor` the
`receive.fsck.skipList` and `fetch.fsck.skipList` variables will not
fall back on the `fsck.skipList` configuration if they aren't set. To
uniformly configure the same fsck settings in different circumstances,
all three of them must be set to the same values.
+
Older versions of Git (before 2.20) documented that the object names
list should be sorted. This was never a requirement; the object names
could appear in any order, but when reading the list we tracked whether
the list was sorted for the purposes of an internal binary search
implementation, which could save itself some work with an already sorted
list. Unless you had a humongous list there was no reason to go out of
your way to pre-sort the list. After Git version 2.20 a hash implementation
is used instead, so there's now no reason to pre-sort the list.

fsmonitor.allowRemote::
    By default, the fsmonitor daemon refuses to work with network-mounted
    repositories. Setting `fsmonitor.allowRemote` to `true` overrides this
    behavior.  Only respected when `core.fsmonitor` is set to `true`.

fsmonitor.socketDir::
    This Mac OS-specific option, if set, specifies the directory in
    which to create the Unix domain socket used for communication
    between the fsmonitor daemon and various Git commands. The directory must
    reside on a native Mac OS filesystem.  Only respected when `core.fsmonitor`
    is set to `true`.

gc.aggressiveDepth::
	The depth parameter used in the delta compression
	algorithm used by 'git gc --aggressive'.  This defaults
	to 50, which is the default for the `--depth` option when
	`--aggressive` isn't in use.
+
See the documentation for the `--depth` option in
linkgit:git-repack[1] for more details.

gc.aggressiveWindow::
	The window size parameter used in the delta compression
	algorithm used by 'git gc --aggressive'.  This defaults
	to 250, which is a much more aggressive window size than
	the default `--window` of 10.
+
See the documentation for the `--window` option in
linkgit:git-repack[1] for more details.

gc.auto::
	When there are approximately more than this many loose
	objects in the repository, `git gc --auto` will pack them.
	Some Porcelain commands use this command to perform a
	light-weight garbage collection from time to time.  The
	default value is 6700.
+
Setting this to 0 disables not only automatic packing based on the
number of loose objects, but also any other heuristic `git gc --auto` will
otherwise use to determine if there's work to do, such as
`gc.autoPackLimit`.

gc.autoPackLimit::
	When there are more than this many packs that are not
	marked with `*.keep` file in the repository, `git gc
	--auto` consolidates them into one larger pack.  The
	default value is 50.  Setting this to 0 disables it.
	Setting `gc.auto` to 0 will also disable this.
+
See the `gc.bigPackThreshold` configuration variable below. When in
use, it'll affect how the auto pack limit works.

gc.autoDetach::
	Make `git gc --auto` return immediately and run in the background
	if the system supports it. Default is true.

gc.bigPackThreshold::
	If non-zero, all non-cruft packs larger than this limit are kept
	when `git gc` is run. This is very similar to
	`--keep-largest-pack` except that all non-cruft packs that meet
	the threshold are kept, not just the largest pack. Defaults to
	zero. Common unit suffixes of 'k', 'm', or 'g' are supported.
+
Note that if the number of kept packs is more than gc.autoPackLimit,
this configuration variable is ignored, all packs except the base pack
will be repacked. After this the number of packs should go below
gc.autoPackLimit and gc.bigPackThreshold should be respected again.
+
If the amount of memory estimated for `git repack` to run smoothly is
not available and `gc.bigPackThreshold` is not set, the largest pack
will also be excluded (this is the equivalent of running `git gc` with
`--keep-largest-pack`).

gc.writeCommitGraph::
	If true, then gc will rewrite the commit-graph file when
	linkgit:git-gc[1] is run. When using `git gc --auto`
	the commit-graph will be updated if housekeeping is
	required. Default is true. See linkgit:git-commit-graph[1]
	for details.

gc.logExpiry::
	If the file gc.log exists, then `git gc --auto` will print
	its content and exit with status zero instead of running
	unless that file is more than 'gc.logExpiry' old.  Default is
	"1.day".  See `gc.pruneExpire` for more ways to specify its
	value.

gc.packRefs::
	Running `git pack-refs` in a repository renders it
	unclonable by Git versions prior to 1.5.1.2 over dumb
	transports such as HTTP.  This variable determines whether
	'git gc' runs `git pack-refs`. This can be set to `notbare`
	to enable it within all non-bare repos or it can be set to a
	boolean value.  The default is `true`.

gc.cruftPacks::
	Store unreachable objects in a cruft pack (see
	linkgit:git-repack[1]) instead of as loose objects. The default
	is `true`.

gc.maxCruftSize::
	Limit the size of new cruft packs when repacking. When
	specified in addition to `--max-cruft-size`, the command line
	option takes priority. See the `--max-cruft-size` option of
	linkgit:git-repack[1].

gc.pruneExpire::
	When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'
	(and 'repack --cruft --cruft-expiration 2.weeks.ago' if using
	cruft packs via `gc.cruftPacks` or `--cruft`).  Override the
	grace period with this config variable.  The value "now" may be
	used to disable this grace period and always prune unreachable
	objects immediately, or "never" may be used to suppress pruning.
	This feature helps prevent corruption when 'git gc' runs
	concurrently with another process writing to the repository; see
	the "NOTES" section of linkgit:git-gc[1].

gc.worktreePruneExpire::
	When 'git gc' is run, it calls
	'git worktree prune --expire 3.months.ago'.
	This config variable can be used to set a different grace
	period. The value "now" may be used to disable the grace
	period and prune `$GIT_DIR/worktrees` immediately, or "never"
	may be used to suppress pruning.

gc.reflogExpire::
gc.<pattern>.reflogExpire::
	'git reflog expire' removes reflog entries older than
	this time; defaults to 90 days. The value "now" expires all
	entries immediately, and "never" suppresses expiration
	altogether. With "<pattern>" (e.g.
	"refs/stash") in the middle the setting applies only to
	the refs that match the <pattern>.

gc.reflogExpireUnreachable::
gc.<pattern>.reflogExpireUnreachable::
	'git reflog expire' removes reflog entries older than
	this time and are not reachable from the current tip;
	defaults to 30 days. The value "now" expires all entries
	immediately, and "never" suppresses expiration altogether.
	With "<pattern>" (e.g. "refs/stash")
	in the middle, the setting applies only to the refs that
	match the <pattern>.
+
These types of entries are generally created as a result of using `git
commit --amend` or `git rebase` and are the commits prior to the amend
or rebase occurring.  Since these changes are not part of the current
project most users will want to expire them sooner, which is why the
default is more aggressive than `gc.reflogExpire`.

gc.recentObjectsHook::
	When considering whether or not to remove an object (either when
	generating a cruft pack or storing unreachable objects as
	loose), use the shell to execute the specified command(s).
	Interpret their output as object IDs which Git will consider as
	"recent", regardless of their age. By treating their mtimes as
	"now", any objects (and their descendants) mentioned in the
	output will be kept regardless of their true age.
+
Output must contain exactly one hex object ID per line, and nothing
else. Objects which cannot be found in the repository are ignored.
Multiple hooks are supported, but all must exit successfully, else the
operation (either generating a cruft pack or unpacking unreachable
objects) will be halted.

gc.repackFilter::
	When repacking, use the specified filter to move certain
	objects into a separate packfile.  See the
	`--filter=<filter-spec>` option of linkgit:git-repack[1].

gc.repackFilterTo::
	When repacking and using a filter, see `gc.repackFilter`, the
	specified location will be used to create the packfile
	containing the filtered out objects. **WARNING:** The
	specified location should be accessible, using for example the
	Git alternates mechanism, otherwise the repo could be
	considered corrupt by Git as it migh not be able to access the
	objects in that packfile. See the `--filter-to=<dir>` option
	of linkgit:git-repack[1] and the `objects/info/alternates`
	section of linkgit:gitrepository-layout[5].

gc.rerereResolved::
	Records of conflicted merge you resolved earlier are
	kept for this many days when 'git rerere gc' is run.
	You can also use more human-readable "1.month.ago", etc.
	The default is 60 days.  See linkgit:git-rerere[1].

gc.rerereUnresolved::
	Records of conflicted merge you have not resolved are
	kept for this many days when 'git rerere gc' is run.
	You can also use more human-readable "1.month.ago", etc.
	The default is 15 days.  See linkgit:git-rerere[1].

gitcvs.commitMsgAnnotation::
	Append this string to each commit message. Set to empty string
	to disable this feature. Defaults to "via git-CVS emulator".

gitcvs.enabled::
	Whether the CVS server interface is enabled for this repository.
	See linkgit:git-cvsserver[1].

gitcvs.logFile::
	Path to a log file where the CVS server interface well... logs
	various stuff. See linkgit:git-cvsserver[1].

gitcvs.usecrlfattr::
	If true, the server will look up the end-of-line conversion
	attributes for files to determine the `-k` modes to use. If
	the attributes force Git to treat a file as text,
	the `-k` mode will be left blank so CVS clients will
	treat it as text. If they suppress text conversion, the file
	will be set with '-kb' mode, which suppresses any newline munging
	the client might otherwise do. If the attributes do not allow
	the file type to be determined, then `gitcvs.allBinary` is
	used. See linkgit:gitattributes[5].

gitcvs.allBinary::
	This is used if `gitcvs.usecrlfattr` does not resolve
	the correct '-kb' mode to use. If true, all
	unresolved files are sent to the client in
	mode '-kb'. This causes the client to treat them
	as binary files, which suppresses any newline munging it
	otherwise might do. Alternatively, if it is set to "guess",
	then the contents of the file are examined to decide if
	it is binary, similar to `core.autocrlf`.

gitcvs.dbName::
	Database used by git-cvsserver to cache revision information
	derived from the Git repository. The exact meaning depends on the
	used database driver, for SQLite (which is the default driver) this
	is a filename. Supports variable substitution (see
	linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
	Default: '%Ggitcvs.%m.sqlite'

gitcvs.dbDriver::
	Used Perl DBI driver. You can specify any available driver
	for this here, but it might not work. git-cvsserver is tested
	with 'DBD::SQLite', reported to work with 'DBD::Pg', and
	reported *not* to work with 'DBD::mysql'. Experimental feature.
	May not contain double colons (`:`). Default: 'SQLite'.
	See linkgit:git-cvsserver[1].

gitcvs.dbUser, gitcvs.dbPass::
	Database user and password. Only useful if setting `gitcvs.dbDriver`,
	since SQLite has no concept of database users and/or passwords.
	'gitcvs.dbUser' supports variable substitution (see
	linkgit:git-cvsserver[1] for details).

gitcvs.dbTableNamePrefix::
	Database table name prefix.  Prepended to the names of any
	database tables used, allowing a single database to be used
	for several repositories.  Supports variable substitution (see
	linkgit:git-cvsserver[1] for details).  Any non-alphabetic
	characters will be replaced with underscores.

All gitcvs variables except for `gitcvs.usecrlfattr` and
`gitcvs.allBinary` can also be specified as
'gitcvs.<access_method>.<varname>' (where 'access_method'
is one of "ext" and "pserver") to make them apply only for the given
access method.

gitweb.category::
gitweb.description::
gitweb.owner::
gitweb.url::
	See linkgit:gitweb[1] for description.

gitweb.avatar::
gitweb.blame::
gitweb.grep::
gitweb.highlight::
gitweb.patches::
gitweb.pickaxe::
gitweb.remote_heads::
gitweb.showSizes::
gitweb.snapshot::
	See linkgit:gitweb.conf[5] for description.

gpg.program::
	Use this custom program instead of "`gpg`" found on `$PATH` when
	making or verifying a PGP signature. The program must support the
	same command-line interface as GPG, namely, to verify a detached
	signature, "`gpg --verify $signature - <$file`" is run, and the
	program is expected to signal a good signature by exiting with
	code 0.  To generate an ASCII-armored detached signature, the
	standard input of "`gpg -bsau $key`" is fed with the contents to be
	signed, and the program is expected to send the result to its
	standard output.

gpg.format::
	Specifies which key format to use when signing with `--gpg-sign`.
	Default is "openpgp". Other possible values are "x509", "ssh".
+
See linkgit:gitformat-signature[5] for the signature format, which differs
based on the selected `gpg.format`.

gpg.<format>.program::
	Use this to customize the program used for the signing format you
	chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still
	be used as a legacy synonym for `gpg.openpgp.program`. The default
	value for `gpg.x509.program` is "gpgsm" and `gpg.ssh.program` is "ssh-keygen".

gpg.minTrustLevel::
	Specifies a minimum trust level for signature verification.  If
	this option is unset, then signature verification for merge
	operations requires a key with at least `marginal` trust.  Other
	operations that perform signature verification require a key
	with at least `undefined` trust.  Setting this option overrides
	the required trust-level for all operations.  Supported values,
	in increasing order of significance:
+
* `undefined`
* `never`
* `marginal`
* `fully`
* `ultimate`

gpg.ssh.defaultKeyCommand::
	This command will be run when user.signingkey is not set and a ssh
	signature is requested. On successful exit a valid ssh public key
	prefixed with `key::` is expected in the first line of its output.
	This allows for a script doing a dynamic lookup of the correct public
	key when it is impractical to statically configure `user.signingKey`.
	For example when keys or SSH Certificates are rotated frequently or
	selection of the right key depends on external factors unknown to git.

gpg.ssh.allowedSignersFile::
	A file containing ssh public keys which you are willing to trust.
	The file consists of one or more lines of principals followed by an ssh
	public key.
	e.g.: `user1@example.com,user2@example.com ssh-rsa AAAAX1...`
	See ssh-keygen(1) "ALLOWED SIGNERS" for details.
	The principal is only used to identify the key and is available when
	verifying a signature.
+
SSH has no concept of trust levels like gpg does. To be able to differentiate
between valid signatures and trusted signatures the trust level of a signature
verification is set to `fully` when the public key is present in the allowedSignersFile.
Otherwise the trust level is `undefined` and git verify-commit/tag will fail.
+
This file can be set to a location outside of the repository and every developer
maintains their own trust store. A central repository server could generate this
file automatically from ssh keys with push access to verify the code against.
In a corporate setting this file is probably generated at a global location
from automation that already handles developer ssh keys.
+
A repository that only allows signed commits can store the file
in the repository itself using a path relative to the top-level of the working tree.
This way only committers with an already valid key can add or change keys in the keyring.
+
Since OpensSSH 8.8 this file allows specifying a key lifetime using valid-after &
valid-before options. Git will mark signatures as valid if the signing key was
valid at the time of the signature's creation. This allows users to change a
signing key without invalidating all previously made signatures.
+
Using a SSH CA key with the cert-authority option
(see ssh-keygen(1) "CERTIFICATES") is also valid.

gpg.ssh.revocationFile::
	Either a SSH KRL or a list of revoked public keys (without the principal prefix).
	See ssh-keygen(1) for details.
	If a public key is found in this file then it will always be treated
	as having trust level "never" and signatures will show as invalid.

grep.lineNumber::
	If set to true, enable `-n` option by default.

grep.column::
	If set to true, enable the `--column` option by default.

grep.patternType::
	Set the default matching behavior. Using a value of 'basic', 'extended',
	'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`,
	`--fixed-strings`, or `--perl-regexp` option accordingly, while the
	value 'default' will use the `grep.extendedRegexp` option to choose
	between 'basic' and 'extended'.

grep.extendedRegexp::
	If set to true, enable `--extended-regexp` option by default. This
	option is ignored when the `grep.patternType` option is set to a value
	other than 'default'.

grep.threads::
	Number of grep worker threads to use. If unset (or set to 0), Git will
	use as many threads as the number of logical cores available.

grep.fullName::
	If set to true, enable `--full-name` option by default.

grep.fallbackToNoIndex::
	If set to true, fall back to `git grep --no-index` if `git grep`
	is executed outside of a git repository.  Defaults to false.

gui.commitMsgWidth::
	Defines how wide the commit message window is in the
	linkgit:git-gui[1]. "75" is the default.

gui.diffContext::
	Specifies how many context lines should be used in calls to diff
	made by the linkgit:git-gui[1]. The default is "5".

gui.displayUntracked::
	Determines if linkgit:git-gui[1] shows untracked files
	in the file list. The default is "true".

gui.encoding::
	Specifies the default character encoding to use for displaying of
	file contents in linkgit:git-gui[1] and linkgit:gitk[1].
	It can be overridden by setting the 'encoding' attribute
	for relevant files (see linkgit:gitattributes[5]).
	If this option is not set, the tools default to the
	locale encoding.

gui.matchTrackingBranch::
	Determines if new branches created with linkgit:git-gui[1] should
	default to tracking remote branches with matching names or
	not. Default: "false".

gui.newBranchTemplate::
	Is used as a suggested name when creating new branches using the
	linkgit:git-gui[1].

gui.pruneDuringFetch::
	"true" if linkgit:git-gui[1] should prune remote-tracking branches when
	performing a fetch. The default value is "false".

gui.trustmtime::
	Determines if linkgit:git-gui[1] should trust the file modification
	timestamp or not. By default the timestamps are not trusted.

gui.spellingDictionary::
	Specifies the dictionary used for spell checking commit messages in
	the linkgit:git-gui[1]. When set to "none" spell checking is turned
	off.

gui.fastCopyBlame::
	If true, 'git gui blame' uses `-C` instead of `-C -C` for original
	location detection. It makes blame significantly faster on huge
	repositories at the expense of less thorough copy detection.

gui.copyBlameThreshold::
	Specifies the threshold to use in 'git gui blame' original location
	detection, measured in alphanumeric characters. See the
	linkgit:git-blame[1] manual for more information on copy detection.

gui.blamehistoryctx::
	Specifies the radius of history context in days to show in
	linkgit:gitk[1] for the selected commit, when the `Show History
	Context` menu item is invoked from 'git gui blame'. If this
	variable is set to zero, the whole history is shown.

guitool.<name>.cmd::
	Specifies the shell command line to execute when the corresponding item
	of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
	mandatory for every tool. The command is executed from the root of
	the working directory, and in the environment it receives the name of
	the tool as `GIT_GUITOOL`, the name of the currently selected file as
	'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
	the head is detached, 'CUR_BRANCH' is empty).

guitool.<name>.needsFile::
	Run the tool only if a diff is selected in the GUI. It guarantees
	that 'FILENAME' is not empty.

guitool.<name>.noConsole::
	Run the command silently, without creating a window to display its
	output.

guitool.<name>.noRescan::
	Don't rescan the working directory for changes after the tool
	finishes execution.

guitool.<name>.confirm::
	Show a confirmation dialog before actually running the tool.

guitool.<name>.argPrompt::
	Request a string argument from the user, and pass it to the tool
	through the `ARGS` environment variable. Since requesting an
	argument implies confirmation, the 'confirm' option has no effect
	if this is enabled. If the option is set to 'true', 'yes', or '1',
	the dialog uses a built-in generic prompt; otherwise the exact
	value of the variable is used.

guitool.<name>.revPrompt::
	Request a single valid revision from the user, and set the
	`REVISION` environment variable. In other aspects this option
	is similar to 'argPrompt', and can be used together with it.

guitool.<name>.revUnmerged::
	Show only unmerged branches in the 'revPrompt' subdialog.
	This is useful for tools similar to merge or rebase, but not
	for things like checkout or reset.

guitool.<name>.title::
	Specifies the title to use for the prompt dialog. The default
	is the tool name.

guitool.<name>.prompt::
	Specifies the general prompt string to display at the top of
	the dialog, before subsections for 'argPrompt' and 'revPrompt'.
	The default value includes the actual command.

help.browser::
	Specify the browser that will be used to display help in the
	'web' format. See linkgit:git-help[1].

help.format::
	Override the default help format used by linkgit:git-help[1].
	Values 'man', 'info', 'web' and 'html' are supported. 'man' is
	the default. 'web' and 'html' are the same.

help.autoCorrect::
	If git detects typos and can identify exactly one valid command similar
	to the error, git will try to suggest the correct command or even
	run the suggestion automatically. Possible config values are:
	 - 0 (default): show the suggested command.
	 - positive number: run the suggested command after specified
deciseconds (0.1 sec).
	 - "immediate": run the suggested command immediately.
	 - "prompt": show the suggestion and prompt for confirmation to run
the command.
	 - "never": don't run or show any suggested command.

help.htmlPath::
	Specify the path where the HTML documentation resides. File system paths
	and URLs are supported. HTML pages will be prefixed with this path when
	help is displayed in the 'web' format. This defaults to the documentation
	path of your Git installation.

http.proxy::
	Override the HTTP proxy, normally configured using the 'http_proxy',
	'https_proxy', and 'all_proxy' environment variables (see `curl(1)`). In
	addition to the syntax understood by curl, it is possible to specify a
	proxy string with a user name but no password, in which case git will
	attempt to acquire one in the same way it does for other credentials. See
	linkgit:gitcredentials[7] for more information. The syntax thus is
	'[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden
	on a per-remote basis; see remote.<name>.proxy

http.proxyAuthMethod::
	Set the method with which to authenticate against the HTTP proxy. This
	only takes effect if the configured proxy string contains a user name part
	(i.e. is of the form 'user@host' or 'user@host:port'). This can be
	overridden on a per-remote basis; see `remote.<name>.proxyAuthMethod`.
	Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment
	variable.  Possible values are:
+
--
* `anyauth` - Automatically pick a suitable authentication method. It is
  assumed that the proxy answers an unauthenticated request with a 407
  status code and one or more Proxy-authenticate headers with supported
  authentication methods. This is the default.
* `basic` - HTTP Basic authentication
* `digest` - HTTP Digest authentication; this prevents the password from being
  transmitted to the proxy in clear text
* `negotiate` - GSS-Negotiate authentication (compare the --negotiate option
  of `curl(1)`)
* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`)
--

http.proxySSLCert::
	The pathname of a file that stores a client certificate to use to authenticate
	with an HTTPS proxy. Can be overridden by the `GIT_PROXY_SSL_CERT` environment
	variable.

http.proxySSLKey::
	The pathname of a file that stores a private key to use to authenticate with
	an HTTPS proxy. Can be overridden by the `GIT_PROXY_SSL_KEY` environment
	variable.

http.proxySSLCertPasswordProtected::
	Enable Git's password prompt for the proxy SSL certificate.  Otherwise OpenSSL
	will prompt the user, possibly many times, if the certificate or private key
	is encrypted. Can be overridden by the `GIT_PROXY_SSL_CERT_PASSWORD_PROTECTED`
	environment variable.

http.proxySSLCAInfo::
	Pathname to the file containing the certificate bundle that should be used to
	verify the proxy with when using an HTTPS proxy. Can be overridden by the
	`GIT_PROXY_SSL_CAINFO` environment variable.

http.emptyAuth::
	Attempt authentication without seeking a username or password.  This
	can be used to attempt GSS-Negotiate authentication without specifying
	a username in the URL, as libcurl normally requires a username for
	authentication.

http.delegation::
	Control GSSAPI credential delegation. The delegation is disabled
	by default in libcurl since version 7.21.7. Set parameter to tell
	the server what it is allowed to delegate when it comes to user
	credentials. Used with GSS/kerberos. Possible values are:
+
--
* `none` - Don't allow any delegation.
* `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the
  Kerberos service ticket, which is a matter of realm policy.
* `always` - Unconditionally allow the server to delegate.
--


http.extraHeader::
	Pass an additional HTTP header when communicating with a server.  If
	more than one such entry exists, all of them are added as extra
	headers.  To allow overriding the settings inherited from the system
	config, an empty value will reset the extra headers to the empty list.

http.cookieFile::
	The pathname of a file containing previously stored cookie lines,
	which should be used
	in the Git http session, if they match the server. The file format
	of the file to read cookies from should be plain HTTP headers or
	the Netscape/Mozilla cookie file format (see `curl(1)`).
	NOTE that the file specified with http.cookieFile is used only as
	input unless http.saveCookies is set.

http.saveCookies::
	If set, store cookies received during requests to the file specified by
	http.cookieFile. Has no effect if http.cookieFile is unset.

http.version::
	Use the specified HTTP protocol version when communicating with a server.
	If you want to force the default. The available and default version depend
	on libcurl. Currently the possible values of
	this option are:

	- HTTP/2
	- HTTP/1.1

http.curloptResolve::
	Hostname resolution information that will be used first by
	libcurl when sending HTTP requests.  This information should
	be in one of the following formats:

	- [+]HOST:PORT:ADDRESS[,ADDRESS]
	- -HOST:PORT

+
The first format redirects all requests to the given `HOST:PORT`
to the provided `ADDRESS`(s). The second format clears all
previous config values for that `HOST:PORT` combination.  To
allow easy overriding of all the settings inherited from the
system config, an empty value will reset all resolution
information to the empty list.

http.sslVersion::
	The SSL version to use when negotiating an SSL connection, if you
	want to force the default.  The available and default version
	depend on whether libcurl was built against NSS or OpenSSL and the
	particular configuration of the crypto library in use. Internally
	this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl
	documentation for more details on the format of this option and
	for the ssl version supported. Currently the possible values of
	this option are:

	- sslv2
	- sslv3
	- tlsv1
	- tlsv1.0
	- tlsv1.1
	- tlsv1.2
	- tlsv1.3

+
Can be overridden by the `GIT_SSL_VERSION` environment variable.
To force git to use libcurl's default ssl version and ignore any
explicit http.sslversion option, set `GIT_SSL_VERSION` to the
empty string.

http.sslCipherList::
  A list of SSL ciphers to use when negotiating an SSL connection.
  The available ciphers depend on whether libcurl was built against
  NSS or OpenSSL and the particular configuration of the crypto
  library in use.  Internally this sets the 'CURLOPT_SSL_CIPHER_LIST'
  option; see the libcurl documentation for more details on the format
  of this list.
+
Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable.
To force git to use libcurl's default cipher list and ignore any
explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the
empty string.

http.sslVerify::
	Whether to verify the SSL certificate when fetching or pushing
	over HTTPS. Defaults to true. Can be overridden by the
	`GIT_SSL_NO_VERIFY` environment variable.

http.sslCert::
	File containing the SSL certificate when fetching or pushing
	over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment
	variable.

http.sslKey::
	File containing the SSL private key when fetching or pushing
	over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment
	variable.

http.sslCertPasswordProtected::
	Enable Git's password prompt for the SSL certificate.  Otherwise
	OpenSSL will prompt the user, possibly many times, if the
	certificate or private key is encrypted.  Can be overridden by the
	`GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable.

http.sslCAInfo::
	File containing the certificates to verify the peer with when
	fetching or pushing over HTTPS. Can be overridden by the
	`GIT_SSL_CAINFO` environment variable.

http.sslCAPath::
	Path containing files with the CA certificates to verify the peer
	with when fetching or pushing over HTTPS. Can be overridden
	by the `GIT_SSL_CAPATH` environment variable.

http.sslBackend::
	Name of the SSL backend to use (e.g. "openssl" or "schannel").
	This option is ignored if cURL lacks support for choosing the SSL
	backend at runtime.

http.schannelCheckRevoke::
	Used to enforce or disable certificate revocation checks in cURL
	when http.sslBackend is set to "schannel". Defaults to `true` if
	unset. Only necessary to disable this if Git consistently errors
	and the message is about checking the revocation status of a
	certificate. This option is ignored if cURL lacks support for
	setting the relevant SSL option at runtime.

http.schannelUseSSLCAInfo::
	As of cURL v7.60.0, the Secure Channel backend can use the
	certificate bundle provided via `http.sslCAInfo`, but that would
	override the Windows Certificate Store. Since this is not desirable
	by default, Git will tell cURL not to use that bundle by default
	when the `schannel` backend was configured via `http.sslBackend`,
	unless `http.schannelUseSSLCAInfo` overrides this behavior.

http.pinnedPubkey::
	Public key of the https service. It may either be the filename of
	a PEM or DER encoded public key file or a string starting with
	'sha256//' followed by the base64 encoded sha256 hash of the
	public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will
	exit with an error if this option is set but not supported by
	cURL.

http.sslTry::
	Attempt to use AUTH SSL/TLS and encrypted data transfers
	when connecting via regular FTP protocol. This might be needed
	if the FTP server requires it for security reasons or you wish
	to connect securely whenever remote FTP server supports it.
	Default is false since it might trigger certificate verification
	errors on misconfigured servers.

http.maxRequests::
	How many HTTP requests to launch in parallel. Can be overridden
	by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5.

http.minSessions::
	The number of curl sessions (counted across slots) to be kept across
	requests. They will not be ended with curl_easy_cleanup() until
	http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
	value will be capped at 1. Defaults to 1.

http.postBuffer::
	Maximum size in bytes of the buffer used by smart HTTP
	transports when POSTing data to the remote system.
	For requests larger than this buffer size, HTTP/1.1 and
	Transfer-Encoding: chunked is used to avoid creating a
	massive pack file locally.  Default is 1 MiB, which is
	sufficient for most requests.
+
Note that raising this limit is only effective for disabling chunked
transfer encoding and therefore should be used only where the remote
server or a proxy only supports HTTP/1.0 or is noncompliant with the
HTTP standard.  Raising this is not, in general, an effective solution
for most push problems, but can increase memory consumption
significantly since the entire buffer is allocated even for small
pushes.

http.lowSpeedLimit, http.lowSpeedTime::
	If the HTTP transfer speed, in bytes per second, is less than
	'http.lowSpeedLimit' for longer than 'http.lowSpeedTime' seconds,
	the transfer is aborted.
	Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and
	`GIT_HTTP_LOW_SPEED_TIME` environment variables.

http.noEPSV::
	A boolean which disables using of EPSV ftp command by curl.
	This can be helpful with some "poor" ftp servers which don't
	support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV`
	environment variable. Default is false (curl will use EPSV).

http.userAgent::
	The HTTP USER_AGENT string presented to an HTTP server.  The default
	value represents the version of the Git client such as git/1.7.1.
	This option allows you to override this value to a more common value
	such as Mozilla/4.0.  This may be necessary, for instance, if
	connecting through a firewall that restricts HTTP connections to a set
	of common USER_AGENT strings (but not including those like git/1.7.1).
	Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable.

http.followRedirects::
	Whether git should follow HTTP redirects. If set to `true`, git
	will transparently follow any redirect issued by a server it
	encounters. If set to `false`, git will treat all redirects as
	errors. If set to `initial`, git will follow redirects only for
	the initial request to a remote, but not for subsequent
	follow-up HTTP requests. Since git uses the redirected URL as
	the base for the follow-up requests, this is generally
	sufficient. The default is `initial`.

http.<url>.*::
	Any of the http.* options above can be applied selectively to some URLs.
	For a config key to match a URL, each element of the config key is
	compared to that of the URL, in the following order:
+
--
. Scheme (e.g., `https` in `https://example.com/`). This field
  must match exactly between the config key and the URL.

. Host/domain name (e.g., `example.com` in `https://example.com/`).
  This field must match between the config key and the URL. It is
  possible to specify a `*` as part of the host name to match all subdomains
  at this level. `https://*.example.com/` for example would match
  `https://foo.example.com/`, but not `https://foo.bar.example.com/`.

. Port number (e.g., `8080` in `http://example.com:8080/`).
  This field must match exactly between the config key and the URL.
  Omitted port numbers are automatically converted to the correct
  default for the scheme before matching.

. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
  path field of the config key must match the path field of the URL
  either exactly or as a prefix of slash-delimited path elements.  This means
  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
  key with just path `foo/`).

. User name (e.g., `user` in `https://user@example.com/repo.git`). If
  the config key has a user name it must match the user name in the
  URL exactly. If the config key does not have a user name, that
  config key will match a URL with any user name (including none),
  but at a lower precedence than a config key with a user name.
--
+
The list above is ordered by decreasing precedence; a URL that matches
a config key's path is preferred to one that matches its user name. For example,
if the URL is `https://user@example.com/foo/bar` a config key match of
`https://example.com/foo` will be preferred over a config key match of
`https://user@example.com`.
+
All URLs are normalized before attempting any matching (the password part,
if embedded in the URL, is always ignored for matching purposes) so that
equivalent URLs that are simply spelled differently will match properly.
Environment variable settings always override any matches.  The URLs that are
matched against are those given directly to Git commands.  This means any URLs
visited as a result of a redirection do not participate in matching.

i18n.commitEncoding::
	Character encoding the commit messages are stored in; Git itself
	does not care per se, but this information is necessary e.g. when
	importing commits from emails or in the gitk graphical history
	browser (and possibly in other places in the future or in other
	porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.

i18n.logOutputEncoding::
	Character encoding the commit messages are converted to when
	running 'git log' and friends.

imap.folder::
	The folder to drop the mails into, which is typically the Drafts
	folder. For example: "INBOX.Drafts", "INBOX/Drafts" or
	"[Gmail]/Drafts". Required.

imap.tunnel::
	Command used to set up a tunnel to the IMAP server through which
	commands will be piped instead of using a direct network connection
	to the server. Required when imap.host is not set.

imap.host::
	A URL identifying the server. Use an `imap://` prefix for non-secure
	connections and an `imaps://` prefix for secure connections.
	Ignored when imap.tunnel is set, but required otherwise.

imap.user::
	The username to use when logging in to the server.

imap.pass::
	The password to use when logging in to the server.

imap.port::
	An integer port number to connect to on the server.
	Defaults to 143 for imap:// hosts and 993 for imaps:// hosts.
	Ignored when imap.tunnel is set.

imap.sslverify::
	A boolean to enable/disable verification of the server certificate
	used by the SSL/TLS connection. Default is `true`. Ignored when
	imap.tunnel is set.

imap.preformattedHTML::
	A boolean to enable/disable the use of html encoding when sending
	a patch.  An html encoded patch will be bracketed with <pre>
	and have a content type of text/html.  Ironically, enabling this
	option causes Thunderbird to send the patch as a plain/text,
	format=fixed email.  Default is `false`.

imap.authMethod::
	Specify the authentication method for authenticating with the IMAP server.
	If Git was built with the NO_CURL option, or if your curl version is older
	than 7.34.0, or if you're running git-imap-send with the `--no-curl`
	option, the only supported method is 'CRAM-MD5'. If this is not set
	then 'git imap-send' uses the basic IMAP plaintext LOGIN command.

include.path::
includeIf.<condition>.path::
	Special variables to include other configuration files. See
	the "CONFIGURATION FILE" section in the main
	linkgit:git-config[1] documentation,
	specifically the "Includes" and "Conditional Includes" subsections.

index.recordEndOfIndexEntries::
	Specifies whether the index file should include an "End Of Index
	Entry" section. This reduces index load time on multiprocessor
	machines but produces a message "ignoring EOIE extension" when
	reading the index using Git versions before 2.20. Defaults to
	'true' if index.threads has been explicitly enabled, 'false'
	otherwise.

index.recordOffsetTable::
	Specifies whether the index file should include an "Index Entry
	Offset Table" section. This reduces index load time on
	multiprocessor machines but produces a message "ignoring IEOT
	extension" when reading the index using Git versions before 2.20.
	Defaults to 'true' if index.threads has been explicitly enabled,
	'false' otherwise.

index.sparse::
	When enabled, write the index using sparse-directory entries. This
	has no effect unless `core.sparseCheckout` and
	`core.sparseCheckoutCone` are both enabled. Defaults to 'false'.

index.threads::
	Specifies the number of threads to spawn when loading the index.
	This is meant to reduce index load time on multiprocessor machines.
	Specifying 0 or 'true' will cause Git to auto-detect the number of
	CPUs and set the number of threads accordingly. Specifying 1 or
	'false' will disable multithreading. Defaults to 'true'.

index.version::
	Specify the version with which new index files should be
	initialized.  This does not affect existing repositories.
	If `feature.manyFiles` is enabled, then the default is 4.

index.skipHash::
	When enabled, do not compute the trailing hash for the index file.
	This accelerates Git commands that manipulate the index, such as
	`git add`, `git commit`, or `git status`. Instead of storing the
	checksum, write a trailing set of bytes with value zero, indicating
	that the computation was skipped.
+
If you enable `index.skipHash`, then Git clients older than 2.13.0 will
refuse to parse the index and Git clients older than 2.40.0 will report an
error during `git fsck`.

:see-git-init:
:see-git-init: (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)

`init.templateDir`::
	Specify the directory from which templates will be copied. {see-git-init}
`init.defaultBranch`::
	Allows overriding the default branch name e.g. when initializing
	a new repository.

instaweb.browser::
	Specify the program that will be used to browse your working
	repository in gitweb. See linkgit:git-instaweb[1].

instaweb.httpd::
	The HTTP daemon command-line to start gitweb on your working
	repository. See linkgit:git-instaweb[1].

instaweb.local::
	If true the web server started by linkgit:git-instaweb[1] will
	be bound to the local IP (127.0.0.1).

instaweb.modulePath::
	The default module path for linkgit:git-instaweb[1] to use
	instead of /usr/lib/apache2/modules.  Only used if httpd
	is Apache.

instaweb.port::
	The port number to bind the gitweb httpd to. See
	linkgit:git-instaweb[1].

interactive.singleKey::
	In interactive commands, allow the user to provide one-letter
	input with a single key (i.e., without hitting enter).
	Currently this is used by the `--patch` mode of
	linkgit:git-add[1], linkgit:git-checkout[1],
	linkgit:git-restore[1], linkgit:git-commit[1],
	linkgit:git-reset[1], and linkgit:git-stash[1].

interactive.diffFilter::
	When an interactive command (such as `git add --patch`) shows
	a colorized diff, git will pipe the diff through the shell
	command defined by this configuration variable. The command may
	mark up the diff further for human consumption, provided that it
	retains a one-to-one correspondence with the lines in the
	original diff. Defaults to disabled (no filtering).

log.abbrevCommit::
	If true, makes linkgit:git-log[1], linkgit:git-show[1], and
	linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
	override this option with `--no-abbrev-commit`.

log.date::
	Set the default date-time mode for the 'log' command.
	Setting a value for log.date is similar to using 'git log''s
	`--date` option.  See linkgit:git-log[1] for details.
+
If the format is set to "auto:foo" and the pager is in use, format
"foo" will be used for the date format. Otherwise, "default" will
be used.

log.decorate::
	Print out the ref names of any commits that are shown by the log
	command. If 'short' is specified, the ref name prefixes 'refs/heads/',
	'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
	specified, the full ref name (including prefix) will be printed.
	If 'auto' is specified, then if the output is going to a terminal,
	the ref names are shown as if 'short' were given, otherwise no ref
	names are shown. This is the same as the `--decorate` option
	of the `git log`.

log.initialDecorationSet::
	By default, `git log` only shows decorations for certain known ref
	namespaces. If 'all' is specified, then show all refs as
	decorations.

log.excludeDecoration::
	Exclude the specified patterns from the log decorations. This is
	similar to the `--decorate-refs-exclude` command-line option, but
	the config option can be overridden by the `--decorate-refs`
	option.

log.diffMerges::
	Set diff format to be used when `--diff-merges=on` is
	specified, see `--diff-merges` in linkgit:git-log[1] for
	details. Defaults to `separate`.

log.follow::
	If `true`, `git log` will act as if the `--follow` option was used when
	a single <path> is given.  This has the same limitations as `--follow`,
	i.e. it cannot be used to follow multiple files and does not work well
	on non-linear history.

log.graphColors::
	A list of colors, separated by commas, that can be used to draw
	history lines in `git log --graph`.

log.showRoot::
	If true, the initial commit will be shown as a big creation event.
	This is equivalent to a diff against an empty tree.
	Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
	normally hide the root commit will now show it. True by default.

log.showSignature::
	If true, makes linkgit:git-log[1], linkgit:git-show[1], and
	linkgit:git-whatchanged[1] assume `--show-signature`.

log.mailmap::
	If true, makes linkgit:git-log[1], linkgit:git-show[1], and
	linkgit:git-whatchanged[1] assume `--use-mailmap`, otherwise
	assume `--no-use-mailmap`. True by default.

lsrefs.unborn::
	May be "advertise" (the default), "allow", or "ignore". If "advertise",
	the server will respond to the client sending "unborn" (as described in
	linkgit:gitprotocol-v2[5]) and will advertise support for this feature during the
	protocol v2 capability advertisement. "allow" is the same as
	"advertise" except that the server will not advertise support for this
	feature; this is useful for load-balanced servers that cannot be
	updated atomically (for example), since the administrator could
	configure "allow", then after a delay, configure "advertise".

mailinfo.scissors::
	If true, makes linkgit:git-mailinfo[1] (and therefore
	linkgit:git-am[1]) act by default as if the --scissors option
	was provided on the command-line. When active, this feature
	removes everything from the message body before a scissors
	line (i.e. consisting mainly of ">8", "8<" and "-").

mailmap.file::
	The location of an augmenting mailmap file. The default
	mailmap, located in the root of the repository, is loaded
	first, then the mailmap file pointed to by this variable.
	The location of the mailmap file may be in a repository
	subdirectory, or somewhere outside of the repository itself.
	See linkgit:git-shortlog[1] and linkgit:git-blame[1].

mailmap.blob::
	Like `mailmap.file`, but consider the value as a reference to a
	blob in the repository. If both `mailmap.file` and
	`mailmap.blob` are given, both are parsed, with entries from
	`mailmap.file` taking precedence. In a bare repository, this
	defaults to `HEAD:.mailmap`. In a non-bare repository, it
	defaults to empty.

maintenance.auto::
	This boolean config option controls whether some commands run
	`git maintenance run --auto` after doing their normal work. Defaults
	to true.

maintenance.strategy::
	This string config option provides a way to specify one of a few
	recommended schedules for background maintenance. This only affects
	which tasks are run during `git maintenance run --schedule=X`
	commands, provided no `--task=<task>` arguments are provided.
	Further, if a `maintenance.<task>.schedule` config value is set,
	then that value is used instead of the one provided by
	`maintenance.strategy`. The possible strategy strings are:
+
* `none`: This default setting implies no tasks are run at any schedule.
* `incremental`: This setting optimizes for performing small maintenance
  activities that do not delete any data. This does not schedule the `gc`
  task, but runs the `prefetch` and `commit-graph` tasks hourly, the
  `loose-objects` and `incremental-repack` tasks daily, and the `pack-refs`
  task weekly.

maintenance.<task>.enabled::
	This boolean config option controls whether the maintenance task
	with name `<task>` is run when no `--task` option is specified to
	`git maintenance run`. These config values are ignored if a
	`--task` option exists. By default, only `maintenance.gc.enabled`
	is true.

maintenance.<task>.schedule::
	This config option controls whether or not the given `<task>` runs
	during a `git maintenance run --schedule=<frequency>` command. The
	value must be one of "hourly", "daily", or "weekly".

maintenance.commit-graph.auto::
	This integer config option controls how often the `commit-graph` task
	should be run as part of `git maintenance run --auto`. If zero, then
	the `commit-graph` task will not run with the `--auto` option. A
	negative value will force the task to run every time. Otherwise, a
	positive value implies the command should run when the number of
	reachable commits that are not in the commit-graph file is at least
	the value of `maintenance.commit-graph.auto`. The default value is
	100.

maintenance.loose-objects.auto::
	This integer config option controls how often the `loose-objects` task
	should be run as part of `git maintenance run --auto`. If zero, then
	the `loose-objects` task will not run with the `--auto` option. A
	negative value will force the task to run every time. Otherwise, a
	positive value implies the command should run when the number of
	loose objects is at least the value of `maintenance.loose-objects.auto`.
	The default value is 100.

maintenance.incremental-repack.auto::
	This integer config option controls how often the `incremental-repack`
	task should be run as part of `git maintenance run --auto`. If zero,
	then the `incremental-repack` task will not run with the `--auto`
	option. A negative value will force the task to run every time.
	Otherwise, a positive value implies the command should run when the
	number of pack-files not in the multi-pack-index is at least the value
	of `maintenance.incremental-repack.auto`. The default value is 10.

man.viewer::
	Specify the programs that may be used to display help in the
	'man' format. See linkgit:git-help[1].

man.<tool>.cmd::
	Specify the command to invoke the specified man viewer. The
	specified command is evaluated in shell with the man page
	passed as an argument. (See linkgit:git-help[1].)

man.<tool>.path::
	Override the path for the given tool that may be used to
	display help in the 'man' format. See linkgit:git-help[1].

merge.conflictStyle::
	Specify the style in which conflicted hunks are written out to
	working tree files upon merge.  The default is "merge", which
	shows a `<<<<<<<` conflict marker, changes made by one side,
	a `=======` marker, changes made by the other side, and then
	a `>>>>>>>` marker.  An alternate style, "diff3", adds a `|||||||`
	marker and the original text before the `=======` marker.  The
	"merge" style tends to produce smaller conflict regions than diff3,
	both because of the exclusion of the original text, and because
	when a subset of lines match on the two sides, they are just pulled
	out of the conflict region.  Another alternate style, "zdiff3", is
	similar to diff3 but removes matching lines on the two sides from
	the conflict region when those matching lines appear near either
	the beginning or end of a conflict region.

merge.defaultToUpstream::
	If merge is called without any commit argument, merge the upstream
	branches configured for the current branch by using their last
	observed values stored in their remote-tracking branches.
	The values of the `branch.<current branch>.merge` that name the
	branches at the remote named by `branch.<current branch>.remote`
	are consulted, and then they are mapped via `remote.<remote>.fetch`
	to their corresponding remote-tracking branches, and the tips of
	these tracking branches are merged. Defaults to true.

merge.ff::
	By default, Git does not create an extra merge commit when merging
	a commit that is a descendant of the current commit. Instead, the
	tip of the current branch is fast-forwarded. When set to `false`,
	this variable tells Git to create an extra merge commit in such
	a case (equivalent to giving the `--no-ff` option from the command
	line). When set to `only`, only such fast-forward merges are
	allowed (equivalent to giving the `--ff-only` option from the
	command line).

merge.verifySignatures::
	If true, this is equivalent to the --verify-signatures command
	line option. See linkgit:git-merge[1] for details.

merge.branchdesc::
	In addition to branch names, populate the log message with
	the branch description text associated with them.  Defaults
	to false.

merge.log::
	In addition to branch names, populate the log message with at
	most the specified number of one-line descriptions from the
	actual commits that are being merged.  Defaults to false, and
	true is a synonym for 20.

merge.suppressDest::
	By adding a glob that matches the names of integration
	branches to this multi-valued configuration variable, the
	default merge message computed for merges into these
	integration branches will omit "into <branch name>" from
	its title.
+
An element with an empty value can be used to clear the list
of globs accumulated from previous configuration entries.
When there is no `merge.suppressDest` variable defined, the
default value of `master` is used for backward compatibility.

merge.renameLimit::
	The number of files to consider in the exhaustive portion of
	rename detection during a merge.  If not specified, defaults
	to the value of diff.renameLimit.  If neither
	merge.renameLimit nor diff.renameLimit are specified,
	currently defaults to 7000.  This setting has no effect if
	rename detection is turned off.

merge.renames::
	Whether Git detects renames.  If set to "false", rename detection
	is disabled. If set to "true", basic rename detection is enabled.
	Defaults to the value of diff.renames.

merge.directoryRenames::
	Whether Git detects directory renames, affecting what happens at
	merge time to new files added to a directory on one side of
	history when that directory was renamed on the other side of
	history.  If merge.directoryRenames is set to "false", directory
	rename detection is disabled, meaning that such new files will be
	left behind in the old directory.  If set to "true", directory
	rename detection is enabled, meaning that such new files will be
	moved into the new directory.  If set to "conflict", a conflict
	will be reported for such paths.  If merge.renames is false,
	merge.directoryRenames is ignored and treated as false.  Defaults
	to "conflict".

merge.renormalize::
	Tell Git that canonical representation of files in the
	repository has changed over time (e.g. earlier commits record
	text files with CRLF line endings, but recent ones use LF line
	endings).  In such a repository, Git can convert the data
	recorded in commits to a canonical form before performing a
	merge to reduce unnecessary conflicts.  For more information,
	see section "Merging branches with differing checkin/checkout
	attributes" in linkgit:gitattributes[5].

merge.stat::
	Whether to print the diffstat between ORIG_HEAD and the merge result
	at the end of the merge.  True by default.

merge.autoStash::
	When set to true, automatically create a temporary stash entry
	before the operation begins, and apply it after the operation
	ends.  This means that you can run merge on a dirty worktree.
	However, use with care: the final stash application after a
	successful merge might result in non-trivial conflicts.
	This option can be overridden by the `--no-autostash` and
	`--autostash` options of linkgit:git-merge[1].
	Defaults to false.

merge.tool::
	Controls which merge tool is used by linkgit:git-mergetool[1].
	The list below shows the valid built-in values.
	Any other value is treated as a custom merge tool and requires
	that a corresponding mergetool.<tool>.cmd variable is defined.

merge.guitool::
	Controls which merge tool is used by linkgit:git-mergetool[1] when the
	-g/--gui flag is specified. The list below shows the valid built-in values.
	Any other value is treated as a custom merge tool and requires that a
	corresponding mergetool.<guitool>.cmd variable is defined.

Unresolved directive in config/merge.txt - include::../mergetools-merge.txt[]

merge.verbosity::
	Controls the amount of output shown by the recursive merge
	strategy.  Level 0 outputs nothing except a final error
	message if conflicts were detected. Level 1 outputs only
	conflicts, 2 outputs conflicts and file changes.  Level 5 and
	above outputs debugging information.  The default is level 2.
	Can be overridden by the `GIT_MERGE_VERBOSITY` environment variable.

merge.<driver>.name::
	Defines a human-readable name for a custom low-level
	merge driver.  See linkgit:gitattributes[5] for details.

merge.<driver>.driver::
	Defines the command that implements a custom low-level
	merge driver.  See linkgit:gitattributes[5] for details.

merge.<driver>.recursive::
	Names a low-level merge driver to be used when
	performing an internal merge between common ancestors.
	See linkgit:gitattributes[5] for details.

mergetool.<tool>.path::
	Override the path for the given tool.  This is useful in case
	your tool is not in the PATH.

mergetool.<tool>.cmd::
	Specify the command to invoke the specified merge tool.  The
	specified command is evaluated in shell with the following
	variables available: 'BASE' is the name of a temporary file
	containing the common base of the files to be merged, if available;
	'LOCAL' is the name of a temporary file containing the contents of
	the file on the current branch; 'REMOTE' is the name of a temporary
	file containing the contents of the file from the branch being
	merged; 'MERGED' contains the name of the file to which the merge
	tool should write the results of a successful merge.

mergetool.<tool>.hideResolved::
	Allows the user to override the global `mergetool.hideResolved` value
	for a specific tool. See `mergetool.hideResolved` for the full
	description.

mergetool.<tool>.trustExitCode::
	For a custom merge command, specify whether the exit code of
	the merge command can be used to determine whether the merge was
	successful.  If this is not set to true then the merge target file
	timestamp is checked, and the merge is assumed to have been successful
	if the file has been updated; otherwise, the user is prompted to
	indicate the success of the merge.

mergetool.meld.hasOutput::
	Older versions of `meld` do not support the `--output` option.
	Git will attempt to detect whether `meld` supports `--output`
	by inspecting the output of `meld --help`.  Configuring
	`mergetool.meld.hasOutput` will make Git skip these checks and
	use the configured value instead.  Setting `mergetool.meld.hasOutput`
	to `true` tells Git to unconditionally use the `--output` option,
	and `false` avoids using `--output`.

mergetool.meld.useAutoMerge::
	When the `--auto-merge` is given, meld will merge all non-conflicting
	parts automatically, highlight the conflicting parts, and wait for
	user decision.  Setting `mergetool.meld.useAutoMerge` to `true` tells
	Git to unconditionally use the `--auto-merge` option with `meld`.
	Setting this value to `auto` makes git detect whether `--auto-merge`
	is supported and will only use `--auto-merge` when available.  A
	value of `false` avoids using `--auto-merge` altogether, and is the
	default value.

mergetool.<vimdiff variant>.layout::
	Configure the split window layout for vimdiff's `<variant>`, which is any of `vimdiff`,
	`nvimdiff`, `gvimdiff`.
	Upon launching `git mergetool` with `--tool=<variant>` (or without `--tool`
	if `merge.tool` is configured as `<variant>`), Git will consult
	`mergetool.<variant>.layout` to determine the tool's layout. If the
	variant-specific configuration is not available, `vimdiff`'s is used as
	fallback.  If that too is not available, a default layout with 4 windows
	will be used.  To configure the layout, see the `BACKEND SPECIFIC HINTS`
	section in linkgit:git-mergetool[1].

mergetool.hideResolved::
	During a merge, Git will automatically resolve as many conflicts as
	possible and write the 'MERGED' file containing conflict markers around
	any conflicts that it cannot resolve; 'LOCAL' and 'REMOTE' normally
	represent the versions of the file from before Git's conflict
	resolution. This flag causes 'LOCAL' and 'REMOTE' to be overwritten so
	that only the unresolved conflicts are presented to the merge tool. Can
	be configured per-tool via the `mergetool.<tool>.hideResolved`
	configuration variable. Defaults to `false`.

mergetool.keepBackup::
	After performing a merge, the original file with conflict markers
	can be saved as a file with a `.orig` extension.  If this variable
	is set to `false` then this file is not preserved.  Defaults to
	`true` (i.e. keep the backup files).

mergetool.keepTemporaries::
	When invoking a custom merge tool, Git uses a set of temporary
	files to pass to the tool. If the tool returns an error and this
	variable is set to `true`, then these temporary files will be
	preserved; otherwise, they will be removed after the tool has
	exited. Defaults to `false`.

mergetool.writeToTemp::
	Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
	conflicting files in the worktree by default.  Git will attempt
	to use a temporary directory for these files when set `true`.
	Defaults to `false`.

mergetool.prompt::
	Prompt before each invocation of the merge resolution program.

mergetool.guiDefault::
	Set `true` to use the `merge.guitool` by default (equivalent to
	specifying the `--gui` argument), or `auto` to select `merge.guitool`
	or `merge.tool` depending on the presence of a `DISPLAY` environment
	variable value. The default is `false`, where the `--gui` argument
	must be provided explicitly for the `merge.guitool` to be used.

notes.mergeStrategy::
	Which merge strategy to choose by default when resolving notes
	conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
	`cat_sort_uniq`.  Defaults to `manual`.  See the "NOTES MERGE STRATEGIES"
	section of linkgit:git-notes[1] for more information on each strategy.
+
This setting can be overridden by passing the `--strategy` option to
linkgit:git-notes[1].

notes.<name>.mergeStrategy::
	Which merge strategy to choose when doing a notes merge into
	refs/notes/<name>.  This overrides the more general
	"notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
	linkgit:git-notes[1] for more information on the available strategies.

notes.displayRef::
	Which ref (or refs, if a glob or specified more than once), in
	addition to the default set by `core.notesRef` or
	`GIT_NOTES_REF`, to read notes from when showing commit
	messages with the 'git log' family of commands.
+
This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
environment variable, which must be a colon separated list of refs or
globs.
+
A warning will be issued for refs that do not exist,
but a glob that does not match any refs is silently ignored.
+
This setting can be disabled by the `--no-notes` option to the 'git
log' family of commands, or by the `--notes=<ref>` option accepted by
those commands.
+
The effective value of "core.notesRef" (possibly overridden by
GIT_NOTES_REF) is also implicitly added to the list of refs to be
displayed.

notes.rewrite.<command>::
	When rewriting commits with <command> (currently `amend` or
	`rebase`), if this variable is `false`, git will not copy
	notes from the original to the rewritten commit.  Defaults to
	`true`.  See also "`notes.rewriteRef`" below.
+
This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
environment variable, which must be a colon separated list of refs or
globs.

notes.rewriteMode::
	When copying notes during a rewrite (see the
	"notes.rewrite.<command>" option), determines what to do if
	the target commit already has a note.  Must be one of
	`overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
	Defaults to `concatenate`.
+
This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
environment variable.

notes.rewriteRef::
	When copying notes during a rewrite, specifies the (fully
	qualified) ref whose notes should be copied.  May be a glob,
	in which case notes in all matching refs will be copied.  You
	may also specify this configuration several times.
+
Does not have a default value; you must configure this variable to
enable note rewriting.  Set it to `refs/notes/commits` to enable
rewriting for the default commit notes.
+
Can be overridden with the `GIT_NOTES_REWRITE_REF` environment variable.
See `notes.rewrite.<command>` above for a further description of its format.

pack.window::
	The size of the window used by linkgit:git-pack-objects[1] when no
	window size is given on the command line. Defaults to 10.

pack.depth::
	The maximum delta depth used by linkgit:git-pack-objects[1] when no
	maximum depth is given on the command line. Defaults to 50.
	Maximum value is 4095.

pack.windowMemory::
	The maximum size of memory that is consumed by each thread
	in linkgit:git-pack-objects[1] for pack window memory when
	no limit is given on the command line.  The value can be
	suffixed with "k", "m", or "g".  When left unconfigured (or
	set explicitly to 0), there will be no limit.

pack.compression::
	An integer -1..9, indicating the compression level for objects
	in a pack file. -1 is the zlib default. 0 means no
	compression, and 1..9 are various speed/size tradeoffs, 9 being
	slowest.  If not set,  defaults to core.compression.  If that is
	not set,  defaults to -1, the zlib default, which is "a default
	compromise between speed and compression (currently equivalent
	to level 6)."
+
Note that changing the compression level will not automatically recompress
all existing objects. You can force recompression by passing the -F option
to linkgit:git-repack[1].

pack.allowPackReuse::
	When true or "single", and when reachability bitmaps are
	enabled, pack-objects will try to send parts of the bitmapped
	packfile verbatim. When "multi", and when a multi-pack
	reachability bitmap is available, pack-objects will try to send
	parts of all packs in the MIDX.
+
If only a single pack bitmap is available, and `pack.allowPackReuse`
is set to "multi", reuse parts of just the bitmapped packfile. This
can reduce memory and CPU usage to serve fetches, but might result in
sending a slightly larger pack. Defaults to true.

pack.island::
	An extended regular expression configuring a set of delta
	islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1]
	for details.

pack.islandCore::
	Specify an island name which gets to have its objects be
	packed first. This creates a kind of pseudo-pack at the front
	of one pack, so that the objects from the specified island are
	hopefully faster to copy into any pack that should be served
	to a user requesting these objects. In practice this means
	that the island specified should likely correspond to what is
	the most commonly cloned in the repo. See also "DELTA ISLANDS"
	in linkgit:git-pack-objects[1].

pack.deltaCacheSize::
	The maximum memory in bytes used for caching deltas in
	linkgit:git-pack-objects[1] before writing them out to a pack.
	This cache is used to speed up the writing object phase by not
	having to recompute the final delta result once the best match
	for all objects is found.  Repacking large repositories on machines
	which are tight with memory might be badly impacted by this though,
	especially if this cache pushes the system into swapping.
	A value of 0 means no limit. The smallest size of 1 byte may be
	used to virtually disable this cache. Defaults to 256 MiB.

pack.deltaCacheLimit::
	The maximum size of a delta, that is cached in
	linkgit:git-pack-objects[1]. This cache is used to speed up the
	writing object phase by not having to recompute the final delta
	result once the best match for all objects is found.
	Defaults to 1000. Maximum value is 65535.

pack.threads::
	Specifies the number of threads to spawn when searching for best
	delta matches.  This requires that linkgit:git-pack-objects[1]
	be compiled with pthreads otherwise this option is ignored with a
	warning. This is meant to reduce packing time on multiprocessor
	machines. The required amount of memory for the delta search window
	is however multiplied by the number of threads.
	Specifying 0 will cause Git to auto-detect the number of CPUs
	and set the number of threads accordingly.

pack.indexVersion::
	Specify the default pack index version.  Valid values are 1 for
	legacy pack index used by Git versions prior to 1.5.2, and 2 for
	the new pack index with capabilities for packs larger than 4 GB
	as well as proper protection against the repacking of corrupted
	packs.  Version 2 is the default.  Note that version 2 is enforced
	and this config option is ignored whenever the corresponding pack is
	larger than 2 GB.
+
If you have an old Git that does not understand the version 2 `*.idx` file,
cloning or fetching over a non-native protocol (e.g. "http")
that will copy both `*.pack` file and corresponding `*.idx` file from the
other side may give you a repository that cannot be accessed with your
older version of Git. If the `*.pack` file is smaller than 2 GB, however,
you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
the `*.idx` file.

pack.packSizeLimit::
	The maximum size of a pack.  This setting only affects
	packing to a file when repacking, i.e. the git:// protocol
	is unaffected.  It can be overridden by the `--max-pack-size`
	option of linkgit:git-repack[1].  Reaching this limit results
	in the creation of multiple packfiles.
+
Note that this option is rarely useful, and may result in a larger total
on-disk size (because Git will not store deltas between packs) and
worse runtime performance (object lookup within multiple packs is
slower than a single pack, and optimizations like reachability bitmaps
cannot cope with multiple packs).
+
If you need to actively run Git using smaller packfiles (e.g., because your
filesystem does not support large files), this option may help. But if
your goal is to transmit a packfile over a medium that supports limited
sizes (e.g., removable media that cannot store the whole repository),
you are likely better off creating a single large packfile and splitting
it using a generic multi-volume archive tool (e.g., Unix `split`).
+
The minimum size allowed is limited to 1 MiB. The default is unlimited.
Common unit suffixes of 'k', 'm', or 'g' are supported.

pack.useBitmaps::
	When true, git will use pack bitmaps (if available) when packing
	to stdout (e.g., during the server side of a fetch). Defaults to
	true. You should not generally need to turn this off unless
	you are debugging pack bitmaps.

pack.useBitmapBoundaryTraversal::
	When true, Git will use an experimental algorithm for computing
	reachability queries with bitmaps. Instead of building up
	complete bitmaps for all of the negated tips and then OR-ing
	them together, consider negated tips with existing bitmaps as
	additive (i.e. OR-ing them into the result if they exist,
	ignoring them otherwise), and build up a bitmap at the boundary
	instead.
+
When using this algorithm, Git may include too many objects as a result
of not opening up trees belonging to certain UNINTERESTING commits. This
inexactness matches the non-bitmap traversal algorithm.
+
In many cases, this can provide a speed-up over the exact algorithm,
particularly when there is poor bitmap coverage of the negated side of
the query.

pack.useSparse::
	When true, git will default to using the '--sparse' option in
	'git pack-objects' when the '--revs' option is present. This
	algorithm only walks trees that appear in paths that introduce new
	objects. This can have significant performance benefits when
	computing a pack to send a small change. However, it is possible
	that extra objects are added to the pack-file if the included
	commits contain certain types of direct renames. Default is
	`true`.

pack.preferBitmapTips::
	When selecting which commits will receive bitmaps, prefer a
	commit at the tip of any reference that is a suffix of any value
	of this configuration over any other commits in the "selection
	window".
+
Note that setting this configuration to `refs/foo` does not mean that
the commits at the tips of `refs/foo/bar` and `refs/foo/baz` will
necessarily be selected. This is because commits are selected for
bitmaps from within a series of windows of variable length.
+
If a commit at the tip of any reference which is a suffix of any value
of this configuration is seen in a window, it is immediately given
preference over any other commit in that window.

pack.writeBitmaps (deprecated)::
	This is a deprecated synonym for `repack.writeBitmaps`.

pack.writeBitmapHashCache::
	When true, git will include a "hash cache" section in the bitmap
	index (if one is written). This cache can be used to feed git's
	delta heuristics, potentially leading to better deltas between
	bitmapped and non-bitmapped objects (e.g., when serving a fetch
	between an older, bitmapped pack and objects that have been
	pushed since the last gc). The downside is that it consumes 4
	bytes per object of disk space. Defaults to true.
+
When writing a multi-pack reachability bitmap, no new namehashes are
computed; instead, any namehashes stored in an existing bitmap are
permuted into their appropriate location when writing a new bitmap.

pack.writeBitmapLookupTable::
	When true, Git will include a "lookup table" section in the
	bitmap index (if one is written). This table is used to defer
	loading individual bitmaps as late as possible. This can be
	beneficial in repositories that have relatively large bitmap
	indexes. Defaults to false.

pack.readReverseIndex::
	When true, git will read any .rev file(s) that may be available
	(see: linkgit:gitformat-pack[5]). When false, the reverse index
	will be generated from scratch and stored in memory. Defaults to
	true.

pack.writeReverseIndex::
	When true, git will write a corresponding .rev file (see:
	linkgit:gitformat-pack[5])
	for each new packfile that it writes in all places except for
	linkgit:git-fast-import[1] and in the bulk checkin mechanism.
	Defaults to true.

pager.<cmd>::
	If the value is boolean, turns on or off pagination of the
	output of a particular Git subcommand when writing to a tty.
	Otherwise, turns on pagination for the subcommand using the
	pager specified by the value of `pager.<cmd>`.  If `--paginate`
	or `--no-pager` is specified on the command line, it takes
	precedence over this option.  To disable pagination for all
	commands, set `core.pager` or `GIT_PAGER` to `cat`.

pretty.<name>::
	Alias for a --pretty= format string, as specified in
	linkgit:git-log[1]. Any aliases defined here can be used just
	as the built-in pretty formats could. For example,
	running `git config pretty.changelog "format:* %H %s"`
	would cause the invocation `git log --pretty=changelog`
	to be equivalent to running `git log "--pretty=format:* %H %s"`.
	Note that an alias with the same name as a built-in format
	will be silently ignored.

protocol.allow::
	If set, provide a user defined default policy for all protocols which
	don't explicitly have a policy (`protocol.<name>.allow`).  By default,
	if unset, known-safe protocols (http, https, git, ssh) have a
	default policy of `always`, known-dangerous protocols (ext) have a
	default policy of `never`, and all other protocols (including file)
	have a default policy of `user`.  Supported policies:
+
--

* `always` - protocol is always able to be used.

* `never` - protocol is never able to be used.

* `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is
  either unset or has a value of 1.  This policy should be used when you want a
  protocol to be directly usable by the user but don't want it used by commands which
  execute clone/fetch/push commands without user input, e.g. recursive
  submodule initialization.

--

protocol.<name>.allow::
	Set a policy to be used by protocol `<name>` with clone/fetch/push
	commands. See `protocol.allow` above for the available policies.
+
The protocol names currently used by git are:
+
--
  - `file`: any local file-based path (including `file://` URLs,
    or local paths)

  - `git`: the anonymous git protocol over a direct TCP
    connection (or proxy, if configured)

  - `ssh`: git over ssh (including `host:path` syntax,
    `ssh://`, etc).

  - `http`: git over http, both "smart http" and "dumb http".
    Note that this does _not_ include `https`; if you want to configure
    both, you must do so individually.

  - any external helpers are named by their protocol (e.g., use
    `hg` to allow the `git-remote-hg` helper)
--

protocol.version::
	If set, clients will attempt to communicate with a server
	using the specified protocol version.  If the server does
	not support it, communication falls back to version 0.
	If unset, the default is `2`.
	Supported versions:
+
--

* `0` - the original wire protocol.

* `1` - the original wire protocol with the addition of a version string
  in the initial response from the server.

* `2` - Wire protocol version 2, see linkgit:gitprotocol-v2[5].

--

pull.ff::
	By default, Git does not create an extra merge commit when merging
	a commit that is a descendant of the current commit. Instead, the
	tip of the current branch is fast-forwarded. When set to `false`,
	this variable tells Git to create an extra merge commit in such
	a case (equivalent to giving the `--no-ff` option from the command
	line). When set to `only`, only such fast-forward merges are
	allowed (equivalent to giving the `--ff-only` option from the
	command line). This setting overrides `merge.ff` when pulling.

pull.rebase::
	When true, rebase branches on top of the fetched branch, instead
	of merging the default branch from the default remote when "git
	pull" is run. See "branch.<name>.rebase" for setting this on a
	per-branch basis.
+
When `merges` (or just 'm'), pass the `--rebase-merges` option to 'git rebase'
so that the local merge commits are included in the rebase (see
linkgit:git-rebase[1] for details).
+
When the value is `interactive` (or just 'i'), the rebase is run in interactive
mode.
+
*NOTE*: this is a possibly dangerous operation; do *not* use
it unless you understand the implications (see linkgit:git-rebase[1]
for details).

pull.octopus::
	The default merge strategy to use when pulling multiple branches
	at once.

pull.twohead::
	The default merge strategy to use when pulling a single branch.

push.autoSetupRemote::
	If set to "true" assume `--set-upstream` on default push when no
	upstream tracking exists for the current branch; this option
	takes effect with push.default options 'simple', 'upstream',
	and 'current'. It is useful if by default you want new branches
	to be pushed to the default remote (like the behavior of
	'push.default=current') and you also want the upstream tracking
	to be set. Workflows most likely to benefit from this option are
	'simple' central workflows where all branches are expected to
	have the same name on the remote.

push.default::
	Defines the action `git push` should take if no refspec is
	given (whether from the command-line, config, or elsewhere).
	Different values are well-suited for
	specific workflows; for instance, in a purely central workflow
	(i.e. the fetch source is equal to the push destination),
	`upstream` is probably what you want.  Possible values are:
+
--

* `nothing` - do not push anything (error out) unless a refspec is
  given. This is primarily meant for people who want to
  avoid mistakes by always being explicit.

* `current` - push the current branch to update a branch with the same
  name on the receiving end.  Works in both central and non-central
  workflows.

* `upstream` - push the current branch back to the branch whose
  changes are usually integrated into the current branch (which is
  called `@{upstream}`).  This mode only makes sense if you are
  pushing to the same repository you would normally pull from
  (i.e. central workflow).

* `tracking` - This is a deprecated synonym for `upstream`.

* `simple` - push the current branch with the same name on the remote.
+
If you are working on a centralized workflow (pushing to the same repository you
pull from, which is typically `origin`), then you need to configure an upstream
branch with the same name.
+
This mode is the default since Git 2.0, and is the safest option suited for
beginners.

* `matching` - push all branches having the same name on both ends.
  This makes the repository you are pushing to remember the set of
  branches that will be pushed out (e.g. if you always push 'maint'
  and 'master' there and no other branches, the repository you push
  to will have these two branches, and your local 'maint' and
  'master' will be pushed there).
+
To use this mode effectively, you have to make sure _all_ the
branches you would push out are ready to be pushed out before
running 'git push', as the whole point of this mode is to allow you
to push all of the branches in one go.  If you usually finish work
on only one branch and push out the result, while other branches are
unfinished, this mode is not for you.  Also this mode is not
suitable for pushing into a shared central repository, as other
people may add new branches there, or update the tip of existing
branches outside your control.
+
This used to be the default, but not since Git 2.0 (`simple` is the
new default).

--

push.followTags::
	If set to true, enable `--follow-tags` option by default.  You
	may override this configuration at time of push by specifying
	`--no-follow-tags`.

push.gpgSign::
	May be set to a boolean value, or the string 'if-asked'. A true
	value causes all pushes to be GPG signed, as if `--signed` is
	passed to linkgit:git-push[1]. The string 'if-asked' causes
	pushes to be signed if the server supports it, as if
	`--signed=if-asked` is passed to 'git push'. A false value may
	override a value from a lower-priority config file. An explicit
	command-line flag always overrides this config option.

push.pushOption::
	When no `--push-option=<option>` argument is given from the
	command line, `git push` behaves as if each <value> of
	this variable is given as `--push-option=<value>`.
+
This is a multi-valued variable, and an empty value can be used in a
higher priority configuration file (e.g. `.git/config` in a
repository) to clear the values inherited from a lower priority
configuration files (e.g. `$HOME/.gitconfig`).
+
----

Example:

/etc/gitconfig
  push.pushoption = a
  push.pushoption = b

~/.gitconfig
  push.pushoption = c

repo/.git/config
  push.pushoption =
  push.pushoption = b

This will result in only b (a and c are cleared).

----

push.recurseSubmodules::
	May be "check", "on-demand", "only", or "no", with the same behavior
	as that of "push --recurse-submodules".
	If not set, 'no' is used by default, unless 'submodule.recurse' is
	set (in which case a 'true' value means 'on-demand').

push.useForceIfIncludes::
	If set to "true", it is equivalent to specifying
	`--force-if-includes` as an option to linkgit:git-push[1]
	in the command line. Adding `--no-force-if-includes` at the
	time of push overrides this configuration setting.

push.negotiate::
	If set to "true", attempt to reduce the size of the packfile
	sent by rounds of negotiation in which the client and the
	server attempt to find commits in common. If "false", Git will
	rely solely on the server's ref advertisement to find commits
	in common.

push.useBitmaps::
	If set to "false", disable use of bitmaps for "git push" even if
	`pack.useBitmaps` is "true", without preventing other git operations
	from using bitmaps. Default is true.

rebase.backend::
	Default backend to use for rebasing.  Possible choices are
	'apply' or 'merge'.  In the future, if the merge backend gains
	all remaining capabilities of the apply backend, this setting
	may become unused.

rebase.stat::
	Whether to show a diffstat of what changed upstream since the last
	rebase. False by default.

rebase.autoSquash::
	If set to true, enable the `--autosquash` option of
	linkgit:git-rebase[1] by default for interactive mode.
	This can be overridden with the `--no-autosquash` option.

rebase.autoStash::
	When set to true, automatically create a temporary stash entry
	before the operation begins, and apply it after the operation
	ends.  This means that you can run rebase on a dirty worktree.
	However, use with care: the final stash application after a
	successful rebase might result in non-trivial conflicts.
	This option can be overridden by the `--no-autostash` and
	`--autostash` options of linkgit:git-rebase[1].
	Defaults to false.

rebase.updateRefs::
	If set to true enable `--update-refs` option by default.

rebase.missingCommitsCheck::
	If set to "warn", git rebase -i will print a warning if some
	commits are removed (e.g. a line was deleted), however the
	rebase will still proceed. If set to "error", it will print
	the previous warning and stop the rebase, 'git rebase
	--edit-todo' can then be used to correct the error. If set to
	"ignore", no checking is done.
	To drop a commit without warning or error, use the `drop`
	command in the todo list.
	Defaults to "ignore".

rebase.instructionFormat::
	A format string, as specified in linkgit:git-log[1], to be used for the
	todo list during an interactive rebase.  The format will
	automatically have the commit hash prepended to the format.

rebase.abbreviateCommands::
	If set to true, `git rebase` will use abbreviated command names in the
	todo list resulting in something like this:
+
-------------------------------------------
	p deadbee The oneline of the commit
	p fa1afe1 The oneline of the next commit
	...
-------------------------------------------
+
instead of:
+
-------------------------------------------
	pick deadbee The oneline of the commit
	pick fa1afe1 The oneline of the next commit
	...
-------------------------------------------
+
Defaults to false.

rebase.rescheduleFailedExec::
	Automatically reschedule `exec` commands that failed. This only makes
	sense in interactive mode (or when an `--exec` option was provided).
	This is the same as specifying the `--reschedule-failed-exec` option.

rebase.forkPoint::
	If set to false set `--no-fork-point` option by default.

rebase.rebaseMerges::
	Whether and how to set the `--rebase-merges` option by default. Can
	be `rebase-cousins`, `no-rebase-cousins`, or a boolean. Setting to
	true or to `no-rebase-cousins` is equivalent to
	`--rebase-merges=no-rebase-cousins`, setting to `rebase-cousins` is
	equivalent to `--rebase-merges=rebase-cousins`, and setting to false is
	equivalent to `--no-rebase-merges`. Passing `--rebase-merges` on the
	command line, with or without an argument, overrides any
	`rebase.rebaseMerges` configuration.

rebase.maxLabelLength::
	When generating label names from commit subjects, truncate the names to
	this length. By default, the names are truncated to a little less than
	`NAME_MAX` (to allow e.g. `.lock` files to be written for the
	corresponding loose refs).

receive.advertiseAtomic::
	By default, git-receive-pack will advertise the atomic push
	capability to its clients. If you don't want to advertise this
	capability, set this variable to false.

receive.advertisePushOptions::
	When set to true, git-receive-pack will advertise the push options
	capability to its clients. False by default.

receive.autogc::
	By default, git-receive-pack will run "git maintenance run --auto" after
	receiving data from git-push and updating refs.  You can stop
	it by setting this variable to false.

receive.certNonceSeed::
	By setting this variable to a string, `git receive-pack`
	will accept a `git push --signed` and verify it by using
	a "nonce" protected by HMAC using this string as a secret
	key.

receive.certNonceSlop::
	When a `git push --signed` sends a push certificate with a
	"nonce" that was issued by a receive-pack serving the same
	repository within this many seconds, export the "nonce"
	found in the certificate to `GIT_PUSH_CERT_NONCE` to the
	hooks (instead of what the receive-pack asked the sending
	side to include).  This may allow writing checks in
	`pre-receive` and `post-receive` a bit easier.  Instead of
	checking `GIT_PUSH_CERT_NONCE_SLOP` environment variable
	that records by how many seconds the nonce is stale to
	decide if they want to accept the certificate, they only
	can check `GIT_PUSH_CERT_NONCE_STATUS` is `OK`.

receive.fsckObjects::
	If it is set to true, git-receive-pack will check all received
	objects. See `transfer.fsckObjects` for what's checked.
	Defaults to false. If not set, the value of
	`transfer.fsckObjects` is used instead.

receive.fsck.<msg-id>::
	Acts like `fsck.<msg-id>`, but is used by
	linkgit:git-receive-pack[1] instead of
	linkgit:git-fsck[1]. See the `fsck.<msg-id>` documentation for
	details.

receive.fsck.skipList::
	Acts like `fsck.skipList`, but is used by
	linkgit:git-receive-pack[1] instead of
	linkgit:git-fsck[1]. See the `fsck.skipList` documentation for
	details.

receive.keepAlive::
	After receiving the pack from the client, `receive-pack` may
	produce no output (if `--quiet` was specified) while processing
	the pack, causing some networks to drop the TCP connection.
	With this option set, if `receive-pack` does not transmit
	any data in this phase for `receive.keepAlive` seconds, it will
	send a short keepalive packet.  The default is 5 seconds; set
	to 0 to disable keepalives entirely.

receive.unpackLimit::
	If the number of objects received in a push is below this
	limit then the objects will be unpacked into loose object
	files. However if the number of received objects equals or
	exceeds this limit then the received pack will be stored as
	a pack, after adding any missing delta bases.  Storing the
	pack from a push can make the push operation complete faster,
	especially on slow filesystems.  If not set, the value of
	`transfer.unpackLimit` is used instead.

receive.maxInputSize::
	If the size of the incoming pack stream is larger than this
	limit, then git-receive-pack will error out, instead of
	accepting the pack file. If not set or set to 0, then the size
	is unlimited.

receive.denyDeletes::
	If set to true, git-receive-pack will deny a ref update that deletes
	the ref. Use this to prevent such a ref deletion via a push.

receive.denyDeleteCurrent::
	If set to true, git-receive-pack will deny a ref update that
	deletes the currently checked out branch of a non-bare repository.

receive.denyCurrentBranch::
	If set to true or "refuse", git-receive-pack will deny a ref update
	to the currently checked out branch of a non-bare repository.
	Such a push is potentially dangerous because it brings the HEAD
	out of sync with the index and working tree. If set to "warn",
	print a warning of such a push to stderr, but allow the push to
	proceed. If set to false or "ignore", allow such pushes with no
	message. Defaults to "refuse".
+
Another option is "updateInstead" which will update the working
tree if pushing into the current branch.  This option is
intended for synchronizing working directories when one side is not easily
accessible via interactive ssh (e.g. a live web site, hence the requirement
that the working directory be clean). This mode also comes in handy when
developing inside a VM to test and fix code on different Operating Systems.
+
By default, "updateInstead" will refuse the push if the working tree or
the index have any difference from the HEAD, but the `push-to-checkout`
hook can be used to customize this.  See linkgit:githooks[5].

receive.denyNonFastForwards::
	If set to true, git-receive-pack will deny a ref update which is
	not a fast-forward. Use this to prevent such an update via a push,
	even if that push is forced. This configuration variable is
	set when initializing a shared repository.

receive.hideRefs::
	This variable is the same as `transfer.hideRefs`, but applies
	only to `receive-pack` (and so affects pushes, but not fetches).
	An attempt to update or delete a hidden ref by `git push` is
	rejected.

receive.procReceiveRefs::
	This is a multi-valued variable that defines reference prefixes
	to match the commands in `receive-pack`.  Commands matching the
	prefixes will be executed by an external hook "proc-receive",
	instead of the internal `execute_commands` function.  If this
	variable is not defined, the "proc-receive" hook will never be
	used, and all commands will be executed by the internal
	`execute_commands` function.
+
For example, if this variable is set to "refs/for", pushing to reference
such as "refs/for/master" will not create or update a reference named
"refs/for/master", but may create or update a pull request directly by
running the hook "proc-receive".
+
Optional modifiers can be provided in the beginning of the value to filter
commands for specific actions: create (a), modify (m), delete (d).
A `!` can be included in the modifiers to negate the reference prefix entry.
E.g.:
+
	git config --system --add receive.procReceiveRefs ad:refs/heads
	git config --system --add receive.procReceiveRefs !:refs/heads

receive.updateServerInfo::
	If set to true, git-receive-pack will run git-update-server-info
	after receiving data from git-push and updating refs.

receive.shallowUpdate::
	If set to true, .git/shallow can be updated when new refs
	require new shallow roots. Otherwise those refs are rejected.

remote.pushDefault::
	The remote to push to by default.  Overrides
	`branch.<name>.remote` for all branches, and is overridden by
	`branch.<name>.pushRemote` for specific branches.

remote.<name>.url::
	The URL of a remote repository.  See linkgit:git-fetch[1] or
	linkgit:git-push[1].

remote.<name>.pushurl::
	The push URL of a remote repository.  See linkgit:git-push[1].

remote.<name>.proxy::
	For remotes that require curl (http, https and ftp), the URL to
	the proxy to use for that remote.  Set to the empty string to
	disable proxying for that remote.

remote.<name>.proxyAuthMethod::
	For remotes that require curl (http, https and ftp), the method to use for
	authenticating against the proxy in use (probably set in
	`remote.<name>.proxy`). See `http.proxyAuthMethod`.

remote.<name>.fetch::
	The default set of "refspec" for linkgit:git-fetch[1]. See
	linkgit:git-fetch[1].

remote.<name>.push::
	The default set of "refspec" for linkgit:git-push[1]. See
	linkgit:git-push[1].

remote.<name>.mirror::
	If true, pushing to this remote will automatically behave
	as if the `--mirror` option was given on the command line.

remote.<name>.skipDefaultUpdate::
	If true, this remote will be skipped by default when updating
	using linkgit:git-fetch[1] or the `update` subcommand of
	linkgit:git-remote[1].

remote.<name>.skipFetchAll::
	If true, this remote will be skipped by default when updating
	using linkgit:git-fetch[1] or the `update` subcommand of
	linkgit:git-remote[1].

remote.<name>.receivepack::
	The default program to execute on the remote side when pushing.  See
	option --receive-pack of linkgit:git-push[1].

remote.<name>.uploadpack::
	The default program to execute on the remote side when fetching.  See
	option --upload-pack of linkgit:git-fetch-pack[1].

remote.<name>.tagOpt::
	Setting this value to --no-tags disables automatic tag following when
	fetching from remote <name>. Setting it to --tags will fetch every
	tag from remote <name>, even if they are not reachable from remote
	branch heads. Passing these flags directly to linkgit:git-fetch[1] can
	override this setting. See options --tags and --no-tags of
	linkgit:git-fetch[1].

remote.<name>.vcs::
	Setting this to a value <vcs> will cause Git to interact with
	the remote with the git-remote-<vcs> helper.

remote.<name>.prune::
	When set to true, fetching from this remote by default will also
	remove any remote-tracking references that no longer exist on the
	remote (as if the `--prune` option was given on the command line).
	Overrides `fetch.prune` settings, if any.

remote.<name>.pruneTags::
	When set to true, fetching from this remote by default will also
	remove any local tags that no longer exist on the remote if pruning
	is activated in general via `remote.<name>.prune`, `fetch.prune` or
	`--prune`. Overrides `fetch.pruneTags` settings, if any.
+
See also `remote.<name>.prune` and the PRUNING section of
linkgit:git-fetch[1].

remote.<name>.promisor::
	When set to true, this remote will be used to fetch promisor
	objects.

remote.<name>.partialclonefilter::
	The filter that will be applied when fetching from this	promisor remote.
	Changing or clearing this value will only affect fetches for new commits.
	To fetch associated objects for commits already present in the local object
	database, use the `--refetch` option of linkgit:git-fetch[1].

remotes.<group>::
	The list of remotes which are fetched by "git remote update
	<group>".  See linkgit:git-remote[1].

repack.useDeltaBaseOffset::
	By default, linkgit:git-repack[1] creates packs that use
	delta-base offset. If you need to share your repository with
	Git older than version 1.4.4, either directly or via a dumb
	protocol such as http, then you need to set this option to
	"false" and repack. Access from old Git versions over the
	native protocol are unaffected by this option.

repack.packKeptObjects::
	If set to true, makes `git repack` act as if
	`--pack-kept-objects` was passed. See linkgit:git-repack[1] for
	details. Defaults to `false` normally, but `true` if a bitmap
	index is being written (either via `--write-bitmap-index` or
	`repack.writeBitmaps`).

repack.useDeltaIslands::
	If set to true, makes `git repack` act as if `--delta-islands`
	was passed. Defaults to `false`.

repack.writeBitmaps::
	When true, git will write a bitmap index when packing all
	objects to disk (e.g., when `git repack -a` is run).  This
	index can speed up the "counting objects" phase of subsequent
	packs created for clones and fetches, at the cost of some disk
	space and extra time spent on the initial repack.  This has
	no effect if multiple packfiles are created.
	Defaults to true on bare repos, false otherwise.

repack.updateServerInfo::
	If set to false, linkgit:git-repack[1] will not run
	linkgit:git-update-server-info[1]. Defaults to true. Can be overridden
	when true by the `-n` option of linkgit:git-repack[1].

repack.cruftWindow::
repack.cruftWindowMemory::
repack.cruftDepth::
repack.cruftThreads::
	Parameters used by linkgit:git-pack-objects[1] when generating
	a cruft pack and the respective parameters are not given over
	the command line. See similarly named `pack.*` configuration
	variables for defaults and meaning.

rerere.autoUpdate::
	When set to true, `git-rerere` updates the index with the
	resulting contents after it cleanly resolves conflicts using
	previously recorded resolutions.  Defaults to false.

rerere.enabled::
	Activate recording of resolved conflicts, so that identical
	conflict hunks can be resolved automatically, should they be
	encountered again.  By default, linkgit:git-rerere[1] is
	enabled if there is an `rr-cache` directory under the
	`$GIT_DIR`, e.g. if "rerere" was previously used in the
	repository.

revert.reference::
	Setting this variable to true makes `git revert` behave
	as if the `--reference` option is given.

safe.bareRepository::
	Specifies which bare repositories Git will work with. The currently
	supported values are:
+
* `all`: Git works with all bare repositories. This is the default.
* `explicit`: Git only works with bare repositories specified via
  the top-level `--git-dir` command-line option, or the `GIT_DIR`
  environment variable (see linkgit:git[1]).
+
If you do not use bare repositories in your workflow, then it may be
beneficial to set `safe.bareRepository` to `explicit` in your global
config. This will protect you from attacks that involve cloning a
repository that contains a bare repository and running a Git command
within that directory.
+
This config setting is only respected in protected configuration (see
<<SCOPES>>). This prevents untrusted repositories from tampering with
this value.

safe.directory::
	These config entries specify Git-tracked directories that are
	considered safe even if they are owned by someone other than the
	current user. By default, Git will refuse to even parse a Git
	config of a repository owned by someone else, let alone run its
	hooks, and this config setting allows users to specify exceptions,
	e.g. for intentionally shared repositories (see the `--shared`
	option in linkgit:git-init[1]).
+
This is a multi-valued setting, i.e. you can add more than one directory
via `git config --add`. To reset the list of safe directories (e.g. to
override any such directories specified in the system config), add a
`safe.directory` entry with an empty value.
+
This config setting is only respected in protected configuration (see
<<SCOPES>>). This prevents untrusted repositories from tampering with this
value.
+
The value of this setting is interpolated, i.e. `~/<path>` expands to a
path relative to the home directory and `%(prefix)/<path>` expands to a
path relative to Git's (runtime) prefix.
+
To completely opt-out of this security check, set `safe.directory` to the
string `*`. This will allow all repositories to be treated as if their
directory was listed in the `safe.directory` list. If `safe.directory=*`
is set in system config and you want to re-enable this protection, then
initialize your list with an empty value before listing the repositories
that you deem safe.
+
As explained, Git only allows you to access repositories owned by
yourself, i.e. the user who is running Git, by default.  When Git
is running as 'root' in a non Windows platform that provides sudo,
however, git checks the SUDO_UID environment variable that sudo creates
and will allow access to the uid recorded as its value in addition to
the id from 'root'.
This is to make it easy to perform a common sequence during installation
"make && sudo make install".  A git process running under 'sudo' runs as
'root' but the 'sudo' command exports the environment variable to record
which id the original user has.
If that is not what you would prefer and want git to only trust
repositories that are owned by root instead, then you can remove
the `SUDO_UID` variable from root's environment before invoking git.

sendemail.identity::
	A configuration identity. When given, causes values in the
	'sendemail.<identity>' subsection to take precedence over
	values in the 'sendemail' section. The default identity is
	the value of `sendemail.identity`.

sendemail.smtpEncryption::
	See linkgit:git-send-email[1] for description.  Note that this
	setting is not subject to the 'identity' mechanism.

sendemail.smtpSSLCertPath::
	Path to ca-certificates (either a directory or a single file).
	Set it to an empty string to disable certificate verification.

sendemail.<identity>.*::
	Identity-specific versions of the 'sendemail.*' parameters
	found below, taking precedence over those when this
	identity is selected, through either the command-line or
	`sendemail.identity`.

sendemail.multiEdit::
	If true (default), a single editor instance will be spawned to edit
	files you have to edit (patches when `--annotate` is used, and the
	summary when `--compose` is used). If false, files will be edited one
	after the other, spawning a new editor each time.

sendemail.confirm::
	Sets the default for whether to confirm before sending. Must be
	one of 'always', 'never', 'cc', 'compose', or 'auto'. See `--confirm`
	in the linkgit:git-send-email[1] documentation for the meaning of these
	values.

sendemail.aliasesFile::
	To avoid typing long email addresses, point this to one or more
	email aliases files.  You must also supply `sendemail.aliasFileType`.

sendemail.aliasFileType::
	Format of the file(s) specified in sendemail.aliasesFile. Must be
	one of 'mutt', 'mailrc', 'pine', 'elm', 'gnus', or 'sendmail'.
+
What an alias file in each format looks like can be found in
the documentation of the email program of the same name. The
differences and limitations from the standard formats are
described below:
+
--
sendmail;;
*	Quoted aliases and quoted addresses are not supported: lines that
	contain a `"` symbol are ignored.
*	Redirection to a file (`/path/name`) or pipe (`|command`) is not
	supported.
*	File inclusion (`:include: /path/name`) is not supported.
*	Warnings are printed on the standard error output for any
	explicitly unsupported constructs, and any other lines that are not
	recognized by the parser.
--
sendemail.annotate::
sendemail.bcc::
sendemail.cc::
sendemail.ccCmd::
sendemail.chainReplyTo::
sendemail.envelopeSender::
sendemail.from::
sendemail.headerCmd::
sendemail.signedOffByCc::
sendemail.smtpPass::
sendemail.suppressCc::
sendemail.suppressFrom::
sendemail.to::
sendemail.toCmd::
sendemail.smtpDomain::
sendemail.smtpServer::
sendemail.smtpServerPort::
sendemail.smtpServerOption::
sendemail.smtpUser::
sendemail.thread::
sendemail.transferEncoding::
sendemail.validate::
sendemail.xmailer::
	These configuration variables all provide a default for
	linkgit:git-send-email[1] command-line options. See its
	documentation for details.

sendemail.signedOffCc (deprecated)::
	Deprecated alias for `sendemail.signedOffByCc`.

sendemail.smtpBatchSize::
	Number of messages to be sent per connection, after that a relogin
	will happen.  If the value is 0 or undefined, send all messages in
	one connection.
	See also the `--batch-size` option of linkgit:git-send-email[1].

sendemail.smtpReloginDelay::
	Seconds to wait before reconnecting to the smtp server.
	See also the `--relogin-delay` option of linkgit:git-send-email[1].

sendemail.forbidSendmailVariables::
	To avoid common misconfiguration mistakes, linkgit:git-send-email[1]
	will abort with a warning if any configuration options for "sendmail"
	exist. Set this variable to bypass the check.

sequence.editor::
	Text editor used by `git rebase -i` for editing the rebase instruction file.
	The value is meant to be interpreted by the shell when it is used.
	It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
	When not configured, the default commit message editor is used instead.

showBranch.default::
	The default set of branches for linkgit:git-show-branch[1].
	See linkgit:git-show-branch[1].

sparse.expectFilesOutsideOfPatterns::
	Typically with sparse checkouts, files not matching any
	sparsity patterns are marked with a SKIP_WORKTREE bit in the
	index and are missing from the working tree.  Accordingly, Git
	will ordinarily check whether files with the SKIP_WORKTREE bit
	are in fact present in the working tree contrary to
	expectations.  If Git finds any, it marks those paths as
	present by clearing the relevant SKIP_WORKTREE bits.  This
	option can be used to tell Git that such
	present-despite-skipped files are expected and to stop
	checking for them.
+
The default is `false`, which allows Git to automatically recover
from the list of files in the index and working tree falling out of
sync.
+
Set this to `true` if you are in a setup where some external factor
relieves Git of the responsibility for maintaining the consistency
between the presence of working tree files and sparsity patterns.  For
example, if you have a Git-aware virtual file system that has a robust
mechanism for keeping the working tree and the sparsity patterns up to
date based on access patterns.
+
Regardless of this setting, Git does not check for
present-despite-skipped files unless sparse checkout is enabled, so
this config option has no effect unless `core.sparseCheckout` is
`true`.

splitIndex.maxPercentChange::
	When the split index feature is used, this specifies the
	percent of entries the split index can contain compared to the
	total number of entries in both the split index and the shared
	index before a new shared index is written.
	The value should be between 0 and 100. If the value is 0, then
	a new shared index is always written; if it is 100, a new
	shared index is never written.
	By default, the value is 20, so a new shared index is written
	if the number of entries in the split index would be greater
	than 20 percent of the total number of entries.
	See linkgit:git-update-index[1].

splitIndex.sharedIndexExpire::
	When the split index feature is used, shared index files that
	were not modified since the time this variable specifies will
	be removed when a new shared index file is created. The value
	"now" expires all entries immediately, and "never" suppresses
	expiration altogether.
	The default value is "2.weeks.ago".
	Note that a shared index file is considered modified (for the
	purpose of expiration) each time a new split-index file is
	either created based on it or read from it.
	See linkgit:git-update-index[1].

ssh.variant::
	By default, Git determines the command line arguments to use
	based on the basename of the configured SSH command (configured
	using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or
	the config setting `core.sshCommand`). If the basename is
	unrecognized, Git will attempt to detect support of OpenSSH
	options by first invoking the configured SSH command with the
	`-G` (print configuration) option and will subsequently use
	OpenSSH options (if that is successful) or no options besides
	the host and remote command (if it fails).
+
The config variable `ssh.variant` can be set to override this detection.
Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`,
`tortoiseplink`, `simple` (no options except the host and remote command).
The default auto-detection can be explicitly requested using the value
`auto`.  Any other value is treated as `ssh`.  This setting can also be
overridden via the environment variable `GIT_SSH_VARIANT`.
+
The current command-line parameters used for each variant are as
follows:
+
--

* `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command

* `simple` - [username@]host command

* `plink` or `putty` - [-P port] [-4] [-6] [username@]host command

* `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command

--
+
Except for the `simple` variant, command-line parameters are likely to
change as git gains new features.

stash.showIncludeUntracked::
	If this is set to true, the `git stash show` command will show
	the untracked files of a stash entry.  Defaults to false. See
	the description of the 'show' command in linkgit:git-stash[1].

stash.showPatch::
	If this is set to true, the `git stash show` command without an
	option will show the stash entry in patch form.  Defaults to false.
	See the description of the 'show' command in linkgit:git-stash[1].

stash.showStat::
	If this is set to true, the `git stash show` command without an
	option will show a diffstat of the stash entry.  Defaults to true.
	See the description of the 'show' command in linkgit:git-stash[1].

status.relativePaths::
	By default, linkgit:git-status[1] shows paths relative to the
	current directory. Setting this variable to `false` shows paths
	relative to the repository root (this was the default for Git
	prior to v1.5.4).

status.short::
	Set to true to enable --short by default in linkgit:git-status[1].
	The option --no-short takes precedence over this variable.

status.branch::
	Set to true to enable --branch by default in linkgit:git-status[1].
	The option --no-branch takes precedence over this variable.

status.aheadBehind::
	Set to true to enable `--ahead-behind` and false to enable
	`--no-ahead-behind` by default in linkgit:git-status[1] for
	non-porcelain status formats.  Defaults to true.

status.displayCommentPrefix::
	If set to true, linkgit:git-status[1] will insert a comment
	prefix before each output line (starting with
	`core.commentChar`, i.e. `#` by default). This was the
	behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
	Defaults to false.

status.renameLimit::
	The number of files to consider when performing rename detection
	in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
	the value of diff.renameLimit.

status.renames::
	Whether and how Git detects renames in linkgit:git-status[1] and
	linkgit:git-commit[1] .  If set to "false", rename detection is
	disabled. If set to "true", basic rename detection is enabled.
	If set to "copies" or "copy", Git will detect copies, as well.
	Defaults to the value of diff.renames.

status.showStash::
	If set to true, linkgit:git-status[1] will display the number of
	entries currently stashed away.
	Defaults to false.

status.showUntrackedFiles::
	By default, linkgit:git-status[1] and linkgit:git-commit[1] show
	files which are not currently tracked by Git. Directories which
	contain only untracked files, are shown with the directory name
	only. Showing untracked files means that Git needs to lstat() all
	the files in the whole repository, which might be slow on some
	systems. So, this variable controls how the commands display
	the untracked files. Possible values are:
+
--
* `no` - Show no untracked files.
* `normal` - Show untracked files and directories.
* `all` - Show also individual files in untracked directories.
--
+
If this variable is not specified, it defaults to 'normal'.
All usual spellings for Boolean value `true` are taken as `normal`
and `false` as `no`.
This variable can be overridden with the -u|--untracked-files option
of linkgit:git-status[1] and linkgit:git-commit[1].

status.submoduleSummary::
	Defaults to false.
	If this is set to a non-zero number or true (identical to -1 or an
	unlimited number), the submodule summary will be enabled and a
	summary of commits for modified submodules will be shown (see
	--summary-limit option of linkgit:git-submodule[1]). Please note
	that the summary output command will be suppressed for all
	submodules when `diff.ignoreSubmodules` is set to 'all' or only
	for those submodules where `submodule.<name>.ignore=all`. The only
	exception to that rule is that status and commit will show staged
	submodule changes. To
	also view the summary for ignored submodules you can either use
	the --ignore-submodules=dirty command-line option or the 'git
	submodule summary' command, which shows a similar output but does
	not honor these settings.

submodule.<name>.url::
	The URL for a submodule. This variable is copied from the .gitmodules
	file to the git config via 'git submodule init'. The user can change
	the configured URL before obtaining the submodule via 'git submodule
	update'. If neither submodule.<name>.active nor submodule.active are
	set, the presence of this variable is used as a fallback to indicate
	whether the submodule is of interest to git commands.
	See linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.

submodule.<name>.update::
	The method by which a submodule is updated by 'git submodule update',
	which is the only affected command, others such as
	'git checkout --recurse-submodules' are unaffected. It exists for
	historical reasons, when 'git submodule' was the only command to
	interact with submodules; settings like `submodule.active`
	and `pull.rebase` are more specific. It is populated by
	`git submodule init` from the linkgit:gitmodules[5] file.
	See description of 'update' command in linkgit:git-submodule[1].

submodule.<name>.branch::
	The remote branch name for a submodule, used by `git submodule
	update --remote`.  Set this option to override the value found in
	the `.gitmodules` file.  See linkgit:git-submodule[1] and
	linkgit:gitmodules[5] for details.

submodule.<name>.fetchRecurseSubmodules::
	This option can be used to control recursive fetching of this
	submodule. It can be overridden by using the --[no-]recurse-submodules
	command-line option to "git fetch" and "git pull".
	This setting will override that from in the linkgit:gitmodules[5]
	file.

submodule.<name>.ignore::
	Defines under what circumstances "git status" and the diff family show
	a submodule as modified. When set to "all", it will never be considered
	modified (but it will nonetheless show up in the output of status and
	commit when it has been staged), "dirty" will ignore all changes
	to the submodule's work tree and
	takes only differences between the HEAD of the submodule and the commit
	recorded in the superproject into account. "untracked" will additionally
	let submodules with modified tracked files in their work tree show up.
	Using "none" (the default when this option is not set) also shows
	submodules that have untracked files in their work tree as changed.
	This setting overrides any setting made in .gitmodules for this submodule,
	both settings can be overridden on the command line by using the
	"--ignore-submodules" option. The 'git submodule' commands are not
	affected by this setting.

submodule.<name>.active::
	Boolean value indicating if the submodule is of interest to git
	commands.  This config option takes precedence over the
	submodule.active config option. See linkgit:gitsubmodules[7] for
	details.

submodule.active::
	A repeated field which contains a pathspec used to match against a
	submodule's path to determine if the submodule is of interest to git
	commands. See linkgit:gitsubmodules[7] for details.

submodule.recurse::
	A boolean indicating if commands should enable the `--recurse-submodules`
	option by default. Defaults to false.
+
When set to true, it can be deactivated via the
`--no-recurse-submodules` option. Note that some Git commands
lacking this option may call some of the above commands affected by
`submodule.recurse`; for instance `git remote update` will call
`git fetch` but does not have a `--no-recurse-submodules` option.
For these commands a workaround is to temporarily change the
configuration value by using `git -c submodule.recurse=0`.
+
The following list shows the commands that accept
`--recurse-submodules` and whether they are supported by this
setting.

* `checkout`, `fetch`, `grep`, `pull`, `push`, `read-tree`,
`reset`, `restore` and `switch` are always supported.
* `clone` and `ls-files` are not supported.
* `branch` is supported only if `submodule.propagateBranches` is
enabled

submodule.propagateBranches::
	[EXPERIMENTAL] A boolean that enables branching support when
	using `--recurse-submodules` or `submodule.recurse=true`.
	Enabling this will allow certain commands to accept
	`--recurse-submodules` and certain commands that already accept
	`--recurse-submodules` will now consider branches.
	Defaults to false.

submodule.fetchJobs::
	Specifies how many submodules are fetched/cloned at the same time.
	A positive integer allows up to that number of submodules fetched
	in parallel. A value of 0 will give some reasonable default.
	If unset, it defaults to 1.

submodule.alternateLocation::
	Specifies how the submodules obtain alternates when submodules are
	cloned. Possible values are `no`, `superproject`.
	By default `no` is assumed, which doesn't add references. When the
	value is set to `superproject` the submodule to be cloned computes
	its alternates location relative to the superprojects alternate.

submodule.alternateErrorStrategy::
	Specifies how to treat errors with the alternates for a submodule
	as computed via `submodule.alternateLocation`. Possible values are
	`ignore`, `info`, `die`. Default is `die`. Note that if set to `ignore`
	or `info`, and if there is an error with the computed alternate, the
	clone proceeds as if no alternate was specified.

tag.forceSignAnnotated::
	A boolean to specify whether annotated tags created should be GPG signed.
	If `--annotate` is specified on the command line, it takes
	precedence over this option.

tag.sort::
	This variable controls the sort ordering of tags when displayed by
	linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
	value of this variable will be used as the default.

tag.gpgSign::
	A boolean to specify whether all tags should be GPG signed.
	Use of this option when running in an automated script can
	result in a large number of tags being signed. It is therefore
	convenient to use an agent to avoid typing your gpg passphrase
	several times. Note that this option doesn't affect tag signing
	behavior enabled by "-u <keyid>" or "--local-user=<keyid>" options.

tar.umask::
	This variable can be used to restrict the permission bits of
	tar archive entries.  The default is 0002, which turns off the
	world write bit.  The special value "user" indicates that the
	archiving user's umask will be used instead.  See umask(2) and
	linkgit:git-archive[1].

Trace2 config settings are only read from the system and global
config files; repository local and worktree config files and `-c`
command line arguments are not respected.

trace2.normalTarget::
	This variable controls the normal target destination.
	It may be overridden by the `GIT_TRACE2` environment variable.
	The following table shows possible values.

trace2.perfTarget::
	This variable controls the performance target destination.
	It may be overridden by the `GIT_TRACE2_PERF` environment variable.
	The following table shows possible values.

trace2.eventTarget::
	This variable controls the event target destination.
	It may be overridden by the `GIT_TRACE2_EVENT` environment variable.
	The following table shows possible values.
+
--
* `0` or `false` - Disables the target.
* `1` or `true` - Writes to `STDERR`.
* `[2-9]` - Writes to the already opened file descriptor.
* `<absolute-pathname>` - Writes to the file in append mode. If the target
already exists and is a directory, the traces will be written to files (one
per process) underneath the given directory.
* `af_unix:[<socket-type>:]<absolute-pathname>` - Write to a
Unix DomainSocket (on platforms that support them).  Socket
type can be either `stream` or `dgram`; if omitted Git will
try both.
--

trace2.normalBrief::
	Boolean.  When true `time`, `filename`, and `line` fields are
	omitted from normal output.  May be overridden by the
	`GIT_TRACE2_BRIEF` environment variable.  Defaults to false.

trace2.perfBrief::
	Boolean.  When true `time`, `filename`, and `line` fields are
	omitted from PERF output.  May be overridden by the
	`GIT_TRACE2_PERF_BRIEF` environment variable.  Defaults to false.

trace2.eventBrief::
	Boolean.  When true `time`, `filename`, and `line` fields are
	omitted from event output.  May be overridden by the
	`GIT_TRACE2_EVENT_BRIEF` environment variable.  Defaults to false.

trace2.eventNesting::
	Integer.  Specifies desired depth of nested regions in the
	event output.  Regions deeper than this value will be
	omitted.  May be overridden by the `GIT_TRACE2_EVENT_NESTING`
	environment variable.  Defaults to 2.

trace2.configParams::
	A comma-separated list of patterns of "important" config
	settings that should be recorded in the trace2 output.
	For example, `core.*,remote.*.url` would cause the trace2
	output to contain events listing each configured remote.
	May be overridden by the `GIT_TRACE2_CONFIG_PARAMS` environment
	variable.  Unset by default.

trace2.envVars::
	A comma-separated list of "important" environment variables that should
	be recorded in the trace2 output.  For example,
	`GIT_HTTP_USER_AGENT,GIT_CONFIG` would cause the trace2 output to
	contain events listing the overrides for HTTP user agent and the
	location of the Git configuration file (assuming any are set).  May be
	overridden by the `GIT_TRACE2_ENV_VARS` environment variable.  Unset by
	default.

trace2.destinationDebug::
	Boolean.  When true Git will print error messages when a
	trace target destination cannot be opened for writing.
	By default, these errors are suppressed and tracing is
	silently disabled.  May be overridden by the
	`GIT_TRACE2_DST_DEBUG` environment variable.

trace2.maxFiles::
	Integer.  When writing trace files to a target directory, do not
	write additional traces if doing so would exceed this many files. Instead,
	write a sentinel file that will block further tracing to this
	directory. Defaults to 0, which disables this check.

transfer.credentialsInUrl::
	A configured URL can contain plaintext credentials in the form
	`<protocol>://<user>:<password>@<domain>/<path>`. You may want
	to warn or forbid the use of such configuration (in favor of
	using linkgit:git-credential[1]). This will be used on
	linkgit:git-clone[1], linkgit:git-fetch[1], linkgit:git-push[1],
	and any other direct use of the configured URL.
+
Note that this is currently limited to detecting credentials in
`remote.<name>.url` configuration; it won't detect credentials in
`remote.<name>.pushurl` configuration.
+
You might want to enable this to prevent inadvertent credentials
exposure, e.g. because:
+
* The OS or system where you're running git may not provide a way or
  otherwise allow you to configure the permissions of the
  configuration file where the username and/or password are stored.
* Even if it does, having such data stored "at rest" might expose you
  in other ways, e.g. a backup process might copy the data to another
  system.
* The git programs will pass the full URL to one another as arguments
  on the command-line, meaning the credentials will be exposed to other
  unprivileged users on systems that allow them to see the full
  process list of other users. On linux the "hidepid" setting
  documented in procfs(5) allows for configuring this behavior.
+
If such concerns don't apply to you then you probably don't need to be
concerned about credentials exposure due to storing sensitive
data in git's configuration files. If you do want to use this, set
`transfer.credentialsInUrl` to one of these values:
+
* `allow` (default): Git will proceed with its activity without warning.
* `warn`: Git will write a warning message to `stderr` when parsing a URL
  with a plaintext credential.
* `die`: Git will write a failure message to `stderr` when parsing a URL
  with a plaintext credential.

transfer.fsckObjects::
	When `fetch.fsckObjects` or `receive.fsckObjects` are
	not set, the value of this variable is used instead.
	Defaults to false.
+
When set, the fetch or receive will abort in the case of a malformed
object or a link to a nonexistent object. In addition, various other
issues are checked for, including legacy issues (see `fsck.<msg-id>`),
and potential security issues like the existence of a `.GIT` directory
or a malicious `.gitmodules` file (see the release notes for v2.2.1
and v2.17.1 for details). Other sanity and security checks may be
added in future releases.
+
On the receiving side, failing fsckObjects will make those objects
unreachable, see "QUARANTINE ENVIRONMENT" in
linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
instead be left unreferenced in the repository.
+
Due to the non-quarantine nature of the `fetch.fsckObjects`
implementation it cannot be relied upon to leave the object store
clean like `receive.fsckObjects` can.
+
As objects are unpacked they're written to the object store, so there
can be cases where malicious objects get introduced even though the
"fetch" failed, only to have a subsequent "fetch" succeed because only
new incoming objects are checked, not those that have already been
written to the object store. That difference in behavior should not be
relied upon. In the future, such objects may be quarantined for
"fetch" as well.
+
For now, the paranoid need to find some way to emulate the quarantine
environment if they'd like the same protection as "push". E.g. in the
case of an internal mirror do the mirroring in two steps, one to fetch
the untrusted objects, and then do a second "push" (which will use the
quarantine) to another internal repo, and have internal clients
consume this pushed-to repository, or embargo internal fetches and
only allow them once a full "fsck" has run (and no new fetches have
happened in the meantime).

transfer.hideRefs::
	String(s) `receive-pack` and `upload-pack` use to decide which
	refs to omit from their initial advertisements.  Use more than
	one definition to specify multiple prefix strings. A ref that is
	under the hierarchies listed in the value of this variable is
	excluded, and is hidden when responding to `git push` or `git
	fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
	program-specific versions of this config.
+
You may also include a `!` in front of the ref name to negate the entry,
explicitly exposing it, even if an earlier entry marked it as hidden.
If you have multiple hideRefs values, later entries override earlier ones
(and entries in more-specific config files override less-specific ones).
+
If a namespace is in use, the namespace prefix is stripped from each
reference before it is matched against `transfer.hiderefs` patterns. In
order to match refs before stripping, add a `^` in front of the ref name. If
you combine `!` and `^`, `!` must be specified first.
+
For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
is omitted from the advertisements. If `uploadpack.allowRefInWant` is set,
`upload-pack` will treat `want-ref refs/heads/master` in a protocol v2
`fetch` command as if `refs/namespaces/foo/refs/heads/master` did not exist.
`receive-pack`, on the other hand, will still advertise the object id the
ref is pointing to without mentioning its name (a so-called ".have" line).
+
Even if you hide refs, a client may still be able to steal the target
objects via the techniques described in the "SECURITY" section of the
linkgit:gitnamespaces[7] man page; it's best to keep private data in a
separate repository.

transfer.unpackLimit::
	When `fetch.unpackLimit` or `receive.unpackLimit` are
	not set, the value of this variable is used instead.
	The default value is 100.

transfer.advertiseSID::
	Boolean. When true, client and server processes will advertise their
	unique session IDs to their remote counterpart. Defaults to false.

transfer.bundleURI::
	When `true`, local `git clone` commands will request bundle
	information from the remote server (if advertised) and download
	bundles before continuing the clone through the Git protocol.
	Defaults to `false`.

transfer.advertiseObjectInfo::
	When `true`, the `object-info` capability is advertised by
	servers. Defaults to false.

uploadarchive.allowUnreachable::
	If true, allow clients to use `git archive --remote` to request
	any tree, whether reachable from the ref tips or not. See the
	discussion in the "SECURITY" section of
	linkgit:git-upload-archive[1] for more details. Defaults to
	`false`.

uploadpack.hideRefs::
	This variable is the same as `transfer.hideRefs`, but applies
	only to `upload-pack` (and so affects only fetches, not pushes).
	An attempt to fetch a hidden ref by `git fetch` will fail.  See
	also `uploadpack.allowTipSHA1InWant`.

uploadpack.allowTipSHA1InWant::
	When `uploadpack.hideRefs` is in effect, allow `upload-pack`
	to accept a fetch request that asks for an object at the tip
	of a hidden ref (by default, such a request is rejected).
	See also `uploadpack.hideRefs`.  Even if this is false, a client
	may be able to steal objects via the techniques described in the
	"SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
	best to keep private data in a separate repository.

uploadpack.allowReachableSHA1InWant::
	Allow `upload-pack` to accept a fetch request that asks for an
	object that is reachable from any ref tip. However, note that
	calculating object reachability is computationally expensive.
	Defaults to `false`.  Even if this is false, a client may be able
	to steal objects via the techniques described in the "SECURITY"
	section of the linkgit:gitnamespaces[7] man page; it's best to
	keep private data in a separate repository.

uploadpack.allowAnySHA1InWant::
	Allow `upload-pack` to accept a fetch request that asks for any
	object at all.
	Defaults to `false`.

uploadpack.keepAlive::
	When `upload-pack` has started `pack-objects`, there may be a
	quiet period while `pack-objects` prepares the pack. Normally
	it would output progress information, but if `--quiet` was used
	for the fetch, `pack-objects` will output nothing at all until
	the pack data begins. Some clients and networks may consider
	the server to be hung and give up. Setting this option instructs
	`upload-pack` to send an empty keepalive packet every
	`uploadpack.keepAlive` seconds. Setting this option to 0
	disables keepalive packets entirely. The default is 5 seconds.

uploadpack.packObjectsHook::
	If this option is set, when `upload-pack` would run
	`git pack-objects` to create a packfile for a client, it will
	run this shell command instead.  The `pack-objects` command and
	arguments it _would_ have run (including the `git pack-objects`
	at the beginning) are appended to the shell command. The stdin
	and stdout of the hook are treated as if `pack-objects` itself
	was run. I.e., `upload-pack` will feed input intended for
	`pack-objects` to the hook, and expects a completed packfile on
	stdout.
+
Note that this configuration variable is only respected when it is specified
in protected configuration (see <<SCOPES>>). This is a safety measure
against fetching from untrusted repositories.

uploadpack.allowFilter::
	If this option is set, `upload-pack` will support partial
	clone and partial fetch object filtering.

uploadpackfilter.allow::
	Provides a default value for unspecified object filters (see: the
	below configuration variable). If set to `true`, this will also
	enable all filters which get added in the future.
	Defaults to `true`.

uploadpackfilter.<filter>.allow::
	Explicitly allow or ban the object filter corresponding to
	`<filter>`, where `<filter>` may be one of: `blob:none`,
	`blob:limit`, `object:type`, `tree`, `sparse:oid`, or `combine`.
	If using combined filters, both `combine` and all of the nested
	filter kinds must be allowed. Defaults to `uploadpackfilter.allow`.

uploadpackfilter.tree.maxDepth::
	Only allow `--filter=tree:<n>` when `<n>` is no more than the value of
	`uploadpackfilter.tree.maxDepth`. If set, this also implies
	`uploadpackfilter.tree.allow=true`, unless this configuration
	variable had already been set. Has no effect if unset.

uploadpack.allowRefInWant::
	If this option is set, `upload-pack` will support the `ref-in-want`
	feature of the protocol version 2 `fetch` command.  This feature
	is intended for the benefit of load-balanced servers which may
	not have the same view of what OIDs their refs point to due to
	replication delay.

url.<base>.insteadOf::
	Any URL that starts with this value will be rewritten to
	start, instead, with <base>. In cases where some site serves a
	large number of repositories, and serves them with multiple
	access methods, and some users need to use different access
	methods, this feature allows people to specify any of the
	equivalent URLs and have Git automatically rewrite the URL to
	the best alternative for the particular user, even for a
	never-before-seen repository on the site.  When more than one
	insteadOf strings match a given URL, the longest match is used.
+
Note that any protocol restrictions will be applied to the rewritten
URL. If the rewrite changes the URL to use a custom protocol or remote
helper, you may need to adjust the `protocol.*.allow` config to permit
the request.  In particular, protocols you expect to use for submodules
must be set to `always` rather than the default of `user`. See the
description of `protocol.allow` above.

url.<base>.pushInsteadOf::
	Any URL that starts with this value will not be pushed to;
	instead, it will be rewritten to start with <base>, and the
	resulting URL will be pushed to. In cases where some site serves
	a large number of repositories, and serves them with multiple
	access methods, some of which do not allow push, this feature
	allows people to specify a pull-only URL and have Git
	automatically use an appropriate URL to push, even for a
	never-before-seen repository on the site.  When more than one
	pushInsteadOf strings match a given URL, the longest match is
	used.  If a remote has an explicit pushurl, Git will ignore this
	setting for that remote.

user.name::
user.email::
author.name::
author.email::
committer.name::
committer.email::
	The `user.name` and `user.email` variables determine what ends
	up in the `author` and `committer` fields of commit
	objects.
	If you need the `author` or `committer` to be different, the
	`author.name`, `author.email`, `committer.name`, or
	`committer.email` variables can be set.
	All of these can be overridden by the `GIT_AUTHOR_NAME`,
	`GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_NAME`,
	`GIT_COMMITTER_EMAIL`, and `EMAIL` environment variables.
+
Note that the `name` forms of these variables conventionally refer to
some form of a personal name.  See linkgit:git-commit[1] and the
environment variables section of linkgit:git[1] for more information on
these settings and the `credential.username` option if you're looking
for authentication credentials instead.

user.useConfigOnly::
	Instruct Git to avoid trying to guess defaults for `user.email`
	and `user.name`, and instead retrieve the values only from the
	configuration. For example, if you have multiple email addresses
	and would like to use a different one for each repository, then
	with this configuration option set to `true` in the global config
	along with a name, Git will prompt you to set up an email before
	making new commits in a newly cloned repository.
	Defaults to `false`.

user.signingKey::
	If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
	key you want it to automatically when creating a signed tag or
	commit, you can override the default selection with this variable.
	This option is passed unchanged to gpg's --local-user parameter,
	so you may specify a key using any method that gpg supports.
	If gpg.format is set to `ssh` this can contain the path to either
	your private ssh key or the public key when ssh-agent is used.
	Alternatively it can contain a public key prefixed with `key::`
	directly (e.g.: "key::ssh-rsa XXXXXX identifier"). The private key
	needs to be available via ssh-agent. If not set Git will call
	gpg.ssh.defaultKeyCommand (e.g.: "ssh-add -L") and try to use the
	first key available. For backward compatibility, a raw key which
	begins with "ssh-", such as "ssh-rsa XXXXXX identifier", is treated
	as "key::ssh-rsa XXXXXX identifier", but this form is deprecated;
	use the `key::` form instead.

versionsort.prereleaseSuffix (deprecated)::
	Deprecated alias for `versionsort.suffix`.  Ignored if
	`versionsort.suffix` is set.

versionsort.suffix::
	Even when version sort is used in linkgit:git-tag[1], tagnames
	with the same base version but different suffixes are still sorted
	lexicographically, resulting e.g. in prerelease tags appearing
	after the main release (e.g. "1.0-rc1" after "1.0").  This
	variable can be specified to determine the sorting order of tags
	with different suffixes.
+
By specifying a single suffix in this variable, any tagname containing
that suffix will appear before the corresponding main release.  E.g. if
the variable is set to "-rc", then all "1.0-rcX" tags will appear before
"1.0".  If specified multiple times, once per suffix, then the order of
suffixes in the configuration will determine the sorting order of tagnames
with those suffixes.  E.g. if "-pre" appears before "-rc" in the
configuration, then all "1.0-preX" tags will be listed before any
"1.0-rcX" tags.  The placement of the main release tag relative to tags
with various suffixes can be determined by specifying the empty suffix
among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck", and
"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
are listed first, followed by "v4.8", then "v4.8-ckX" and finally
"v4.8-bfsX".
+
If more than one suffix matches the same tagname, then that tagname will
be sorted according to the suffix which starts at the earliest position in
the tagname.  If more than one different matching suffix starts at
that earliest position, then that tagname will be sorted according to the
longest of those suffixes.
The sorting order between different suffixes is undefined if they are
in multiple config files.

web.browser::
	Specify a web browser that may be used by some commands.
	Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
	may use it.

worktree.guessRemote::
	If no branch is specified and neither `-b` nor `-B` nor
	`--detach` is used, then `git worktree add` defaults to
	creating a new branch from HEAD.  If `worktree.guessRemote` is
	set to true, `worktree add` tries to find a remote-tracking
	branch whose name uniquely matches the new branch name.  If
	such a branch exists, it is checked out and set as "upstream"
	for the new branch.  If no such match can be found, it falls
	back to creating a new branch from the current HEAD.
