 # bash completion for the Mercurial distributed SCM
 
 # 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
 #
