   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 cat << EOF > ${__git_tcsh_completion_script}
  27 #!bash
  28 #
  29 # This script is GENERATED and will be overwritten automatically.
  30 # Do not modify it directly.  Instead, modify the git-completion.tcsh
  31 # script provided by Git core.
  32 #

  36 # Set COMP_WORDS in a way that can be handled by the bash script.
  37 COMP_WORDS=(\$1)
  38
  39 # The cursor is at the end of parameter #1.
  40 # We must check for a space as the last character which will
  41 # tell us that the previous word is complete and the cursor
  42 # is on the next word.
  43 if [ "\${1: -1}" == " " ]; then
  44        # The last character is a space, so our location is at the end

  46        COMP_CWORD=\${#COMP_WORDS[@]}
  47 else
  48        # The last character is not a space, so our location is on the
  49        # last word of the command-line array, so we must decrement the
  50        # count by 1
  51        COMP_CWORD=\$((\${#COMP_WORDS[@]}-1))
