Visually select the lines, the use e.g. to add ; at the end of each line do
:normal A;
# or to do this on the entire file run
:%normal A;.
Or to add 'xxx yyy' at the start of every line, visually select then run
:normal 0ixxx yyy
Or to do the last command/edit on a bunch on lines, do a command on a line, then visually select other lines and run
:normal .
# get files to operate on
:args `ag -l ActiveRecord::Base`

- U to open snippets for the FileType (UltiSnipEdit)
- Create a snip with snip
- Move through tabstops with (forward) and (back)
- Snips are stored in
~/.vim/Ultisnips

- to start a spell check, move with ]s or [s
- Use CTRL-N or CTRL-P (in insert mode) to autocomplete word
- Add a new word to the dictionary quickly with zg
Use dig and imgcat (iTerm only) - e.g
digraph {
normal -> insert [label="i"]
insert -> normal [label="ESC"]
normal -> visual [label="V"]
visual -> normal [label="ESC"]
}
:!dot -Tpng % | imgcat
Tips from here
qa start recording a macro to a @a play the macro 6@aa play back the macro 6 times "ap paste the a macro to the screen "aY yank the macro back to a buffer
- use :wn before closing macro recording, to write and move to next file
- to apply 'q' macro globally: :g[lobal]/{reqex to match on lines}/normal @q
- paste the 'q' macro (e.g. in vimrc and then use to map to something): "qp let @i = '{"qp}' quote whatever was pasted from the macro noremap ri :g[lobal]/{regex to match}/normal @i:w
- edit existing 'q' macro visually :let @q='q'
- apply to all 100 open files: 100@q
- apply to all open files, writing and moving to next: (end macro with :wn)
- apply to all recursively: (end 'q' macro with @q)
:g/itemnum/normal 20Ctl+v,Ctrl+a
global / look for lines with itemnum / normal mode / run the 20Ctrl+A command Type Ctrl+v,Ctrl+a to insert the literal character Ctrl+a
:v/itemmnum/normal {cmd}
:v is the inverse of the global command, matching lines that do not contain itemnum
redirect output from a command to register a
:redir @a
run commmand e.g. show last 20 history commands
:history : -20,
Stop further redirection
:redir END
Now in normal mode, paste the history from register a with:
"ap
Build a function around the history of commands like so:
function! MyFunction() silent! .. silent! .. endfunction
command! MyCommand call MyFunction()
Use silent! in front of history commands to silence things, and add normal in front of commands that come after switching to insert mode. Then source this file and try out the command!
:so % :MyCommand
Copy all lines beginning with # (will paste below)
:g/^#/t.
Copy all lines beginning with # and substitute all chars on new line with =
:g/^#/t.|s/./=/g
Match all lines beginning with ** and do something with them (e.g. insert a new line above)
:g/**/normal O # insert a line above :g/**/normal yyp # copy lines and paste below :g/**/d # delete these lines
Substitute ** (indented bullets) while maintaining spaces before them:
:%s/^(\s*)**/\1++/g
Surround regex with ( ) to capture and use \1, \2 etc. in substitution.
OR use \zs
:%s/^\s*\zs**/\1++/g
\zs tells regex to only start substituting from this point forward.
