# This is heavily based off of the git-prompt.bash script that ships with
# git, which is Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>.
# The act of porting the code, along with any new code, are Copyright (C) 2012

#
# By virtue of being based on the git-prompt.bash script, this script is
# distributed under the GNU General Public License, version 2.0.
#
# This script vends a function __fish_git_prompt which takes a format string,
# exactly how the bash script works. This can be used in your fish_prompt
# function.
#
# The behavior of __fish_git_prompt is very heavily based off of the bash
# script's __git_ps1 function. As such, usage and customization is very
# similar, although some extra features are provided in this script.
# Due to differences between bash and fish, the PROMPT_COMMAND style where
# passing two or three arguments causes the fucnction to set PS1 is not
# supported.  More information on the additional features is found after the
# bash-compatable documentation.
#
# The argument to __fish_git_prompt will be displayed only if you are currently
# in a git repository. The %s token will be the name of the branch.
#
# In addition, if you set __fish_git_prompt_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 __fish_git_prompt_showdirtystate is enabled. The
# choice to leave the variable as 'bash' instead of renaming to 'fish' is done
# to preserve compatibility with existing configured repositories.
#
# You can also see if currently something is stashed, by setting
# __fish_git_prompt_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 are untracked files, then you can set
# __fish_git_prompt_showuntrackedfiles to a nonempty value. If there are
# untracked files, then a '%' will be shown next to the branch name. Once you
# have set __fish_git_prompt_showuntrackedfiles, you can override it on a
# per-repository basis by setting the bash.showUntrackedFiles config variable.
# As before, this variable remains named 'bash' to preserve compatibility.
#
# If you would like to see the difference between HEAD and its upstream, set
# __fish_git_prompt_showupstream to '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 behavior by setting
# __fish_git_prompt_showupstream to a space-separated list of values:
#
#     verbose        show number of commits ahead/behind (+/-) upstream
#     informative    similar to verbose, but shows nothing when equal (fish only)
#     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
#
# By default, __fish_git_prompt will compare HEAD to your SVN upstream if it
# can find one, or @{upstream} otherwise. Once you have set
# __fish_git_prompt_showupstream, you can override it on a per-repository basis
# by setting the bash.showUpstream config variable. As before, this variable
# remains named 'bash' to preserve compatibility.
#
# If you would like to see more information about the identity of commits
# checked out as a detached HEAD, set __fish_git_prompt_describe_style to
# one of the following 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
# __fish_git_prompt_showcolorhints to a nonempty value.  The default colors are
# based on the colored output of "git status -sb"


# __fish_git_prompt includes some additional features on top of the
# above-documented bash-compatible features:
#
#
# An "informative git prompt" mode similar to the scripts for bash and zsh
# can be activated by setting __fish_git_prompt_show_informative_status
# This works more like the "informative git prompt" scripts for bash and zsh,
# giving prompts like (master|+1#2*3%4) where master is the current branch
# and you have 1 staged, 2 unmerged, 3 dirty, and 4 untracked files.  If you
# have no changes, it displays (master|.).  The characters and colors can be
# customized as below, with the following names:
#
#     dirtystate, invalidstate, stagedstate, untrackedfiles, cleanstate
#
# The color for each component of the prompt can specified using
# __fish_git_prompt_color_<name>, where <name> is one of the following and the
# values are specified as arguments to `set_color`.  The variable
# __fish_git_prompt_color is used for any component that does not have an
# individual color set.
#
#     prefix     Anything before %s in the format string
#     suffix     Anything after  %s in the format string
#     bare       Marker for a bare repository
#     merging    Current operation (|MERGING, |REBASE, etc.)
#     branch     Branch name
#     flags      Optional flags (see below)
#     upstream   Upstream name and flags (with showupstream)
#
#
# The following optional flags have both colors, as above, and custom
# characters via __fish_git_prompt_char_<name>.  The default character is
# shown in parenthesis.  The default color for these flags can be also be set
# via the __fish_git_prompt_color_flags variable.
#
#   __fish_git_prompt_showdirtystate
#     dirtystate          unstaged changes (*)
#     stagedstate         staged changes   (+)
#     invalidstate        HEAD invalid     (#, colored as stagedstate)
#
#   __fish_git_prompt_showstashstate
#     stashstate          stashed changes  ($)
#
#   __fish_git_prompt_showuntrackedfiles
#     untrackedfiles      untracked files  (%)
#
#   __fish_git_prompt_showupstream  (all colored as upstream)
#     upstream_equal      Branch matches upstream              (=)
#     upstream_behind     Upstream has more commits            (<)
#     upstream_ahead      Branch has more commits              (>)
#     upstream_diverged   Upstream and branch have new commits (<>)
#
#   __fish_git_prompt_show_informative_status
#     (see also the flags for showdirtystate and showuntrackedfiles, above)
#     cleanstate          Working directory has no changes (.)
#
#
# The separator between the branch name and flags can also be customized via
# __fish_git_prompt_char_stateseparator.  It defaults to a space ( ) and can
# only be colored by __fish_git_prompt_color.
#
# The separator before the upstream information can be customized via
# __fish_git_prompt_char_upstream_prefix.  It defaults to a space ( ) and is
# colored as part of the upstream information.
#
# Turning on __fish_git_prompt_showcolorhints changes the colors as follows to
# more closely match the behavior in bash.  Note that setting any of these
# colors manually will override these defaults.
#
#     branch            Defaults to green
#     branch_detached   New color, when head is detached, default red
#     dirtystate        Defaults to red
#     stagedstate       Defaults to green
#     flags             Defaults to --bold blue
