Standard project .git/hooks/pre-push This pre-push hook (which I use for many of my projects) skips pushing branches and tags that start with “wip/”, “tmp/”, or “local/”. This makes it easy to keep commits marked as work-in-progress, temporary, or local-only from leaking upstream. Requires git 1.8.2, in which pre-push hooks were introduced.

pre-push

#!/bin/sh
#
# Hook script that blocks pushing of branches and tags with the form 'wip/*', and commits commits the log message starts
# with "WIP" (work in progress)..
#
# This hook is called with the following parameters:
#
# $1 -- Name of the remote to which the push is being done
# $2 -- URL to which the push is being done
#
# If pushing without using a named remote those arguments will be equal.
#
# Information about the commits which are being pushed is supplied as lines to
# the standard input in the form:
#
#   <local ref> <local sha1> <remote ref> <remote sha1>
#
# This sample shows how to prevent push of commits where the log message starts
# with "WIP" (work in progress).

		# @fixme: This needs to search for commit messages starting with WIP ("\AWIP"), not commit messages with lines that start with WIP ("^WIP").
		# 	It appears, however, that git-rev-list's --grep option only supports basic regexp (ignoring the grep.patternType option), so this will need to be done a differnt way (perhaps with format and a grep statement to check it as a whole).
