Move __fish_git_prompt -> fish_git_prompt

Browse Source 
This exposes it more, since it's quite an important function.

We should do the same with the other vcs functions.

We leave a compatibility shim in place for now.

# based off of the git-prompt script that ships with git
#
# Written by Kevin Ballard <kevin@sb.org>
# Updated by Brian Gernhardt <brian@gernhardtsoftware.com>
#
# 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
# Kevin Ballard <kevin@sb.org>.
#
# 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
# name if verbose, then also show the upstream abbrev name
# informative similar to verbose, but shows nothing when equal (fish only)
# git always compare HEAD to @{upstream}
# svn always compare HEAD to your SVN upstream
# none disables (fish only, useful with show_informative_status)
#
# 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. 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✚5…6) where master is the current branch,
# you have 1 commit your upstream doesn't and it has 2 you don't, and you have
# 3 staged, 4 unmerged, 5 dirty, and 6 untracked files. If you have no
# changes, it displays (master|✔).
#
# Setting __fish_git_prompt_show_informative_status changes several defaults.
# The default mode for __fish_git_prompt_showupstream changes to informative
# and the following characters have their defaults changed. (The characters
# and colors can still be customized as described below.)
#
# upstream_prefix ()
# upstream_ahead (↑)
# upstream_behind (↓)
# stateseparator (|)
# 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 can only be colored by
# __fish_git_prompt_color. It normally defaults to a space ( ) and defaults
# to a vertical bar (|) when __fish_git_prompt_show_informative_status is set.
#
# The separator before the upstream information can be customized via
# __fish_git_prompt_char_upstream_prefix. It is colored like the rest of
# the upstream information. It normally defaults to nothing () and defaults
# to a space ( ) when __fish_git_prompt_showupstream contains verbose.
#
#
# 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
#
#
# The branch name could be shorten via
# __fish_git_prompt_shorten_branch_len. Define the branch max len.
# __fish_git_prompt_shorten_branch_char_suffix. Customize suffixed char of shorten branch. Defaults to (…).

# based off of the git-prompt script that ships with git
#
# Written by Kevin Ballard <kevin@sb.org>
# Updated by Brian Gernhardt <brian@gernhardtsoftware.com>
#
# 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
# Kevin Ballard <kevin@sb.org>.
#
# 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 includes 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
# name if verbose, then also show the upstream abbrev name
# informative similar to verbose, but shows nothing when equal (fish only)
# git always compare HEAD to @{upstream}
# svn always compare HEAD to your SVN upstream
# none disables (fish only, useful with show_informative_status)
#
# 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. 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✚5…6) where master is the current branch,
# you have 1 commit your upstream doesn't and it has 2 you don't, and you have
# 3 staged, 4 unmerged, 5 dirty, and 6 untracked files. If you have no
# changes, it displays (master|✔).
#
# Setting __fish_git_prompt_show_informative_status changes several defaults.
# The default mode for __fish_git_prompt_showupstream changes to informative
# and the following characters have their defaults changed. (The characters
# and colors can still be customized as described below.)
#
# upstream_prefix ()
# upstream_ahead (↑)
# upstream_behind (↓)
# stateseparator (|)
# 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 can only be colored by
# __fish_git_prompt_color. It normally defaults to a space ( ) and defaults
# to a vertical bar (|) when __fish_git_prompt_show_informative_status is set.
#
# The separator before the upstream information can be customized via
# __fish_git_prompt_char_upstream_prefix. It is colored like the rest of
# the upstream information. It normally defaults to nothing () and defaults
# to a space ( ) when __fish_git_prompt_showupstream contains verbose.
#
#
# 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
#
#
# The branch name could be shorten via
# __fish_git_prompt_shorten_branch_len. Define the branch max len.
# __fish_git_prompt_shorten_branch_char_suffix. Customize suffixed char of shorten branch. Defaults to (…).
