# 1) Copy this file to somewhere (e.g. ~/.git-prompt.sh).

# source ~/.git-prompt.sh
-# 3a) In ~/.bashrc set PROMPT_COMMAND=__git_ps1
-# To customize the prompt, provide start/end arguments
-# PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
-# 3b) Alternatively change your PS1 to call __git_ps1 as

# Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '

+# the optional argument will be used as format string.
+# 3b) Alternatively, if you are using bash, __git_ps1 can be
+# used for PROMPT_COMMAND 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.
+# 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.
+# 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
# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
# setting the bash.showUpstream config variable.
#
+# If you would like to see more information about the identity of
+# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
+# to one of these values:
+#
+# contains relative to newer annotated tag (v1.6.3.2~35)
+# branch relative to newer tag or branch (master~4)
+# describe relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
+# default exactly matching tag
+#
# If you would like a colored hint about the current dirty state, set
# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
# the colored output of "git status -sb".
-#
+
# __gitdir accepts 0 or 1 arguments (i.e., location)
# returns location of .git repo
__gitdir ()
# when called from PS1 using command substitution
# in this mode it prints text to add to bash PS1 prompt (includes branch name)
#
-# __git_ps1 requires 2 arguments when called from PROMPT_COMMAND (pc)
+# __git_ps1 requires 2 or 3 arguments when called from PROMPT_COMMAND (pc)
# in that case it _sets_ PS1. The arguments are parts of a PS1 string.
-# when both arguments are given, the first is prepended and the second appended
+# when two arguments are given, the first is prepended and the second appended
# to the state string when assigned to PS1.
+# The optional third parameter will be used as printf format string to further
+# customize the output of the git-status string.
# In this mode you can request colored hints using GIT_PS1_SHOWCOLORHINTS=true
