Git-svn remotes can have a prefix for their remotes. If I set a prefix of 'svn/' then my remote trunk branch is called svn/trunk. Update the script to use the svn-remote.*.fetch key to figure out how the 'trunk' branch is mapped into the remotes namespace and apply this to the current branch. This assumes branches are mapped into the same namespace, which is likely. It also doesn't work for tags, but neither did the old code.

# based off of the git-completion script that ships with git
|

#
|
|
# Written by Kevin Ballard <kevin@sb.org>
|
|
#
|
|
# This is heavily based off of the git-completion.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-completion.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 __fish_git_prompt function. As such, usage and customization is very
|
|
# similar, although some extra flexibility is provided in this script.
|
|
#
|
|
# 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. If HEAD is
|
|
# not a branch, it attempts to show the relevant tag. The tag search is
|
|
# controlled by the __fish_git_prompt_describe_style variable, with the
|
|
# following values:
|
|
# default (or unset) Any tag that exactly matches HEAD
|
|
# contains Nearest annotated tag that contains HEAD
|
|
# branch Nearest tag/branch that contains HEAD
|
|
# describe Output of `git describe`
|
|
#
|
|
# 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're untracked files, then you can set
|
|
# __fish_git_prompt_showuntrackedfiles to a nonempty value. If there're
|
|
# untracked files, then a '%' will be shown next to the branch name.
|
|
#
|
|
# 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, and "<>" indicates you have diverged. You can
|
|
# further control behavior by setting __fish_git_prompt_showupstream to a
|
|
# space-separated list of values:
|
|
# verbose show number of commits head/behind (+/-) upstream
|
|
# 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.
|
|
#
|
|
# This fish-compatible version of __fish_git_prompt includes some additional
|
|
# features on top of the above-documented bash-compatible features:
|
|
#
|
|
# The color for the branch name and each individual optional component can be
|
|
# specified using __fish_git_prompt_color_<name>, where <name> is 'prefix',
|
|
# 'suffix', 'bare', 'merging', 'branch', 'dirtystate', 'stagedstate',
|
|
# 'invalidstate', 'stashstate', 'untrackedfiles', and 'upstream'. The variable
|
|
# __fish_git_prompt_color is used for any component that does not have an
|
|
# individual color set. Colors are specified as arguments to `set_color`.
|
|
#
|
|
# The characters used for the optional features can be configured using
|
|
# __fish_git_prompt_char_<token>, where <token> is one of 'dirtystate',
|
|
# 'stagedstate', 'invalidstate', 'stashstate', 'untrackedfiles',
|
|
# 'upstream_equal', 'upstream_behind', 'upstream_ahead', and
|
|
# 'upstream_diverged'.
