# tcsh completion support for core Git.

# 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:
#
# 0) You need tcsh 6.16.00 or newer.
# 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
# 3) For completion similar to bash, it is recommended to also
# add the following line to your .tcshrc/.cshrc:
# set autolist=ambiguous
# It will tell tcsh to list the possible completion choices.
