Many users want to display the current branch name of the current git repository as part of their PS1 prompt, much as their PS1 prompt might also display the current working directory name. We don't force our own PS1 onto the user. Instead we let them craft their own PS1 string and offer them the function __git_ps1 which they can invoke to obtain either "" (when not in a git repository) or "(%s)" where %s is the name of the current branch, as read from HEAD, with the leading refs/heads/ removed.

# bash completion support for core Git.
|
|
#
|
|
# Copyright (C) 2006 Shawn Pearce
|
|
# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
|
|
#
|
|
# The contained completion routines provide support for completing:
|
|
#
|
|
# *) local and remote branch names
|
|
# *) local and remote tag names
|
|
# *) .git/remotes file names
|
|
# *) git 'subcommands'
|
|
# *) tree paths within 'ref:path/to/file' expressions
|
|
#
|
|
# To use these routines:
|
|
#
|
|
# 1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
|
|
# 2) Added the following line to your .bashrc:
|
|
# source ~/.git-completion.sh
|
|
#
|
|
# 3) Consider changing your PS1 to also show the current branch:
|
|
# PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
|
|
#
|
|
# The argument to __git_ps1 will be displayed only if you
|
|
# are currently in a git repository. The %s token will be
|
|
# the name of the current branch.
|
|
#
