6 | # When sourced, this script will generate a new script that uses | |
7 | # the git-completion.bash script provided by core Git. This new | |
8 | # script can be used by tcsh to perform git completion. | |
9 | # The current script also issues the necessary tcsh 'complete' | |
10 | # commands. | |
11 | # | |
12 | # To use this completion script: | |
13 | # | |
92f1c042 | 14 | # 0) You need tcsh 6.16.00 or newer. |
9673b8c3 MK |
15 | # 1) Copy both this file and the bash completion script to ${HOME}. |
16 | # You _must_ use the name ${HOME}/.git-completion.bash for the | |
17 | # bash script. | |
18 | # (e.g. ~/.git-completion.tcsh and ~/.git-completion.bash). | |
19 | # 2) Add the following line to your .tcshrc/.cshrc: | |
20 | # source ~/.git-completion.tcsh | |
75ed918b MK |
21 | # 3) For completion similar to bash, it is recommended to also |
22 | # add the following line to your .tcshrc/.cshrc: | |
23 | # set autolist=ambiguous | |
24 | # It will tell tcsh to list the possible completion choices. | |
