   8 # When sourced, this script will generate a new script that uses
   9 # the git-completion.bash script provided by core Git.  This new
  10 # script can be used by tcsh to perform git completion.
  11 # The current script also issues the necessary tcsh 'complete'
  12 # commands.
  13 #
  14 # To use this completion script:
  15 #
  16 #    1) Copy both this file and the bash completion script to ${HOME}.
  17 #       You _must_ use the name ${HOME}/.git-completion.bash for the
  18 #       bash script.
  19 #       (e.g. ~/.git-completion.tcsh and ~/.git-completion.bash).
  20 #    2) Add the following line to your .tcshrc/.cshrc:
  21 #        source ~/.git-completion.tcsh
  22
  23 set __git_tcsh_completion_original_script = ${HOME}/.git-completion.bash
  24 set __git_tcsh_completion_script = ${HOME}/.git-completion.tcsh.bash
  25
  26 # Check that the user put the script in the right place
  27 if ( ! -e ${__git_tcsh_completion_original_script} ) then
  28        echo "git-completion.tcsh: Cannot find: ${__git_tcsh_completion_original_script}.  Git completion will not work."
  29        exit

  36 # Do not modify it directly.  Instead, modify the git-completion.tcsh
  37 # script provided by Git core.
