# bash completion for the Mercurial distributed SCM -*- sh -*-
# Docs:
#
# If you source this file from your .bashrc, bash should be able to
# complete a command line that uses hg with all the available commands
# and options and sometimes even arguments.
#
# Mercurial allows you to define additional commands through extensions.
# Bash should be able to automatically figure out the name of these new
# commands and their options. See below for how to define _hg_opt_foo
# and _hg_cmd_foo functions to fine-tune the completion for option and
# non-option arguments, respectively.
#
#
# Notes about completion for specific commands:
#
# - the completion function for the email command from the patchbomb
# extension will try to call _hg_emails to get a list of e-mail
# addresses. It's up to the user to define this function. For
# example, put the addresses of the lists that you usually patchbomb
# in ~/.patchbomb-to and the addresses that you usually use to send
# the patchbombs in ~/.patchbomb-from and use something like this:
#
# _hg_emails()
# {
# if [ -r ~/.patchbomb-$1 ]; then
# cat ~/.patchbomb-$1
# fi
# }
#
#
# Writing completion functions for additional commands:
#
# If it exists, the function _hg_cmd_foo will be called without
# arguments to generate the completion candidates for the hg command
# "foo". If the command receives some arguments that aren't options
# even though they start with a "-", you can define a function called
# _hg_opt_foo to generate the completion candidates. If _hg_opt_foo
# doesn't return 0, regular completion for options is attempted.
#
# In addition to the regular completion variables provided by bash,
# the following variables are also set:
# - $hg - the hg program being used (e.g. /usr/bin/hg)
# - $cmd - the name of the hg command being completed
# - $cmd_index - the index of $cmd in $COMP_WORDS
# - $cur - the current argument being completed
# - $prev - the argument before $cur
# - $global_args - "|"-separated list of global options that accept
# an argument (e.g. '--cwd|-R|--repository')
# - $canonical - 1 if we canonicalized $cmd before calling the function
# 0 otherwise
#
