# This adds completion to bash shells for git cl commands. It is
# meant for developers and not needed for inclusion by any automated
# processes that will, of course, specify the full command, not rely
# on or benefit from tab-completion.
#
# Requires:
#   Installed git bash completion.
#
# Usage:
#   Put something like the following in your .bashrc:
#   . $PATH_TO_DEPOT_TOOLS/git cl_completion.sh
#


# Parses commands from git cl -h.
__git_cl_commands () {
  git cl -h 2> /dev/null | sed -n 's/^\s*\x1b\[32m\(.*\)\x1b\[39m.*$/\1/p'
}

# Caches variables in __git_cl_all_commands.
__git_cl_compute_all_commands () {
  test -n "$__git_cl_all_commands" ||
  __git_cl_all_commands="$(__git_cl_commands)"
}

_git_cl () {
  __git_cl_compute_all_commands
  __gitcomp_nl "$(__git_cl_all_commands)"
}
