# bash/zsh completion support for core Git.
#
# Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
# Distributed under the GNU General Public License, version 2.0.
#
# The contained completion routines provide support for completing:
#
#    *) local and remote branch names
#    *) local and remote tag names
#    *) .git/remotes file names
#    *) git 'subcommands'
#    *) git email aliases for git-send-email
#    *) tree paths within 'ref:path/to/file' expressions
#    *) file paths within current working directory and index
#    *) common --long-options
#
# To use these routines:
#
#    1) Copy this file to somewhere (e.g. ~/.git-completion.bash).
#    2) Add the following line to your .bashrc/.zshrc:
#        source ~/.git-completion.bash
#    3) Consider changing your PS1 to also show the current branch,
#       see git-prompt.sh for details.
#
# If you use complex aliases of form '!f() { ... }; f', you can use the null
# command ':' as the first command in the function body to declare the desired
# completion style.  For example '!f() { : git commit ; ... }; f' will
# tell the completion to use commit completion.  This also works with aliases
# of form "!sh -c '...'".  For example, "!sh -c ': git commit ; ... '".
#
# If you have a command that is not part of git, but you would still
# like completion, you can use __git_complete:
#
#   __git_complete gl git_log
#
# Or if it's a main command (i.e. git or gitk):
#
#   __git_complete gk gitk
#
# Compatible with bash 3.2.57.
#
# You can set the following environment variables to influence the behavior of
# the completion routines:
#
#   GIT_COMPLETION_CHECKOUT_NO_GUESS
#
#     When set to "1", do not include "DWIM" suggestions in git-checkout
#     and git-switch completion (e.g., completing "foo" when "origin/foo"
#     exists).
#
#   GIT_COMPLETION_SHOW_ALL_COMMANDS
#
#     When set to "1" suggest all commands, including plumbing commands
#     which are hidden by default (e.g. "cat-file" on "git ca<TAB>").
#
#   GIT_COMPLETION_SHOW_ALL
#
#     When set to "1" suggest all options, including options which are
#     typically hidden (e.g. '--allow-empty' for 'git commit').
#
#   GIT_COMPLETION_IGNORE_CASE
#
#     When set, uses for-each-ref '--ignore-case' to find refs that match
#     case insensitively, even on systems with case sensitive file systems
#     (e.g., completing tag name "FOO" on "git checkout f<TAB>").

# Usage: __git_complete_refs [<option>]...

# --dwim: List unique remote branches for 'git switch's tracking DWIMery.
# --pfx=<prefix>: A prefix to be added to each ref.
# --cur=<word>: The current ref to be completed.  Defaults to the current
#               word to be completed.
# --sfx=<suffix>: A suffix to be appended to each ref instead of the default

# --mode=<mode>: What set of refs to complete, one of 'refs' (the default) to
#                complete all refs, 'heads' to complete only branches, or
#                'remote-heads' to complete only remote branches. Note that
