# 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. | |
