# This script allows you to see the current branch in your prompt.
# This script allows you to see repository status in your prompt.
#
# To enable:
#
# 1) Copy this file to somewhere (e.g. ~/.git-prompt.sh).
# 2) Add the following line to your .bashrc/.zshrc:
# source ~/.git-prompt.sh
# 3) Change your PS1 to also show the current branch:
# Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
# ZSH: PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
# 3a) Change your PS1 to call __git_ps1 as
# command-substitution:
# Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
# ZSH: setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
# the optional argument will be used as format string.
# 3b) Alternatively, for a slightly faster prompt, __git_ps1 can
# be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
# with two parameters, <pre> and <post>, which are strings
# you would put in $PS1 before and after the status string
# generated by the git-prompt machinery. e.g.
# Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
# will show username, at-sign, host, colon, cwd, then
# various status string, followed by dollar and SP, as
# your prompt.
# ZSH: precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
# will show username, pipe, then various status string,
# followed by colon, cwd, dollar and SP, as your prompt.
# Optionally, you can supply a third argument with a printf
# format string to finetune the output of the branch status
#
# 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.
# The repository status will be displayed only if you are currently in a
# git repository. The %s token is the placeholder for the shown status.
#
# The prompt status always includes the current branch name.

# unstaged (*) and staged (+) changes will be shown next to the branch
