22 | ;;; Commentary: | |
23 | ||
24 | ;; This file contains an interface for the git version control | |
25 | ;; system. It provides easy access to the most frequently used git | |
26 | ;; commands. The user interface is as far as possible identical to | |
27 | ;; that of the PCL-CVS mode. | |
28 | ;; | |
29 | ;; To install: put this file on the load-path and place the following | |
30 | ;; in your .emacs file: | |
31 | ;; | |
32 | ;; (require 'git) | |
33 | ;; | |
34 | ;; To start: `M-x git-status' | |
35 | ;; | |
36 | ;; TODO | |
37 | ;; - portability to XEmacs | |
38 | ;; - better handling of subprocess errors | |
39 | ;; - hook into file save (after-save-hook) | |
40 | ;; - diff against other branch | |
41 | ;; - renaming files from the status buffer | |
711fc8f6 AJ |
42 | ;; - creating tags |
43 | ;; - fetch/pull | |
44 | ;; - switching branches | |
45 | ;; - revlist browser | |
46 | ;; - git-show-branch browser | |
