#!tcsh
#
# tcsh completion support for core Git.
#
# Copyright (C) 2012 Marc Khouzam <marc.khouzam@gmail.com>
# Distributed under the GNU General Public License, version 2.0.
#
# When sourced, this script will generate a new script that uses
# the git-completion.bash script provided by core Git. This new
# script can be used by tcsh to perform git completion.
# The current script also issues the necessary tcsh 'complete'
# commands.
#
# To use this completion script:
#
# 1) Copy both this file and the bash completion script to ${HOME}.
# You _must_ use the name ${HOME}/.git-completion.bash for the
# bash script.
# (e.g. ~/.git-completion.tcsh and ~/.git-completion.bash).
# 2) Add the following line to your .tcshrc/.cshrc:
# source ~/.git-completion.tcsh
set __git_tcsh_completion_original_script = ${HOME}/.git-completion.bash
set __git_tcsh_completion_script = ${HOME}/.git-completion.tcsh.bash
cat << EOF > ${__git_tcsh_completion_script}
#!bash
#
# This script is GENERATED and will be overwritten automatically.
# Do not modify it directly. Instead, modify the git-completion.tcsh
# script provided by Git core.
#
source ${__git_tcsh_completion_original_script}
# Set COMP_WORDS in a way that can be handled by the bash script.
COMP_WORDS=(\$1)
# The cursor is at the end of parameter #1.
# We must check for a space as the last character which will
# tell us that the previous word is complete and the cursor
# is on the next word.
if [ "\${1: -1}" == " " ]; then
# The last character is a space, so our location is at the end
# of the command-line array
COMP_CWORD=\${#COMP_WORDS[@]}
else
# The last character is not a space, so our location is on the
# last word of the command-line array, so we must decrement the
# count by 1
COMP_CWORD=\$((\${#COMP_WORDS[@]}-1))
fi
# Call _git() or _gitk() of the bash script, based on the first
# element of the command-line
_\${COMP_WORDS[0]}
IFS=\$'\n'
echo "\${COMPREPLY[*]}" | sort | uniq
EOF
complete git 'p/*/`bash ${__git_tcsh_completion_script} "${COMMAND_LINE}"`/'
complete gitk 'p/*/`bash ${__git_tcsh_completion_script} "${COMMAND_LINE}"`/'
