# 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.
