The %s token is the placeholder for the shown status. -# -# The prompt status always includes the current branch name. -# -# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value, -# unstaged (*) and staged (+) changes will be shown next to the branch -# name. You can configure this per-repository with the -# bash.showDirtyState variable, which defaults to true once -# GIT_PS1_SHOWDIRTYSTATE is enabled. -# -# You can also see if currently something is stashed, by setting -# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed, -# then a '$' will be shown next to the branch name. -# -# If you would like to see if there're untracked files, then you can set -# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked -# files, then a '%' will be shown next to the branch name. You can -# configure this per-repository with the bash.showUntrackedFiles -# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is -# enabled. -# -# If you would like to see the difference between HEAD and its upstream, -# set GIT_PS1_SHOWUPSTREAM="auto". A "<" indicates you are behind, ">" -# indicates you are ahead, "<>" indicates you have diverged and "=" -# indicates that there is no difference. You can further control -# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list -# of values: -# -# verbose show number of commits ahead/behind (+/-) upstream -# name if verbose, then also show the upstream abbrev name -# legacy don't use the '--count' option available in recent -# versions of git-rev-list -# git always compare HEAD to @{upstream} -# svn always compare HEAD to your SVN upstream -# -# You can change the separator between the branch name and the above -# state symbols by setting GIT_PS1_STATESEPARATOR. The default separator -# is SP. -# -# When there is an in-progress operation such as a merge, rebase, -# revert, cherry-pick, or bisect, the prompt will include information -# related to the operation, often in the form "|<OPERATION-NAME>". -# -# When the repository has a sparse-checkout, a notification of the form -# "|SPARSE" will be included in the prompt. This can be shortened to a -# single '?' character by setting GIT_PS1_COMPRESSSPARSESTATE, or omitted -# by setting GIT_PS1_OMITSPARSESTATE. -# -# By default, __git_ps1 will compare HEAD to your SVN upstream if it can -# find one, or @{upstream} otherwise. Once you have set -# 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) -# tag relative to any older 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" and are available only when -# using __git_ps1 for PROMPT_COMMAND or precmd. -# -# If you would like __git_ps1 to do nothing in the case when the current -# directory is set up to be ignored by git, then set -# GIT_PS1_HIDE_IF_PWD_IGNORED to a nonempty value.
