This can be +done by adding to your .emacs something like this: + + (add-to-list 'load-path ".../git/contrib/emacs") + (require 'git) + (require 'git-blame) + + +The following modules are available: + +* git.el: + + Status manager that displays the state of all the files of the + project, and provides easy access to the most frequently used git + commands. The user interface is as far as possible compatible with + the pcl-cvs mode. It can be started with `M-x git-status'. + +* git-blame.el: + + Emacs implementation of incremental git-blame. When you turn it on + while viewing a file, the editor buffer will be updated by setting + the background of individual lines to a color that reflects which + commit it comes from. And when you move around the buffer, a + one-line summary will be shown in the echo area. + +* vc-git.el: + + This file used to contain the VC-mode backend for git, but it is no + longer distributed with git. It is now maintained as part of Emacs + and included in standard Emacs distributions starting from version + 22.2. + + If you have an earlier Emacs version, upgrading to Emacs 22 is + recommended, since the VC mode in older Emacs is not generic enough + to be able to support git in a reasonable manner, and no attempt has + been made to backport vc-git.el. diff --git a/contrib/emacs/git.el b/contrib/emacs/git.el index fcbe2d9cf5..eace9c18eb 100644 --- a/contrib/emacs/git.el +++ b/contrib/emacs/git.el @@ -530,9 +530,9 @@ Each entry is a cons of (SHORT-NAME .
