Based on suggestions from Mattias Engdegård. * lisp/vc/vc-git.el (vc-git--make-button-text): New function to generate text for stash button. (vc-git-make-stash-button): Show stash counts. Delete and recreate button when toggling. (vc-git-dir-extra-headers): Pass counts to vc-git-make-stash-button. Treat stash count <= vc-git-show-stash as equivalent to showing entire list.

;;; Commentary:
|
||
|
||
;; This file contains a VC backend for the git version control
|
||
;; system.
|
||
;;
|
||
|
||
;;; Installation:
|
||
|
||
;; To install: put this file on the load-path and add Git to the list
|
||
;; of supported backends in `vc-handled-backends'; the following line,
|
||
;; placed in your init file, will accomplish this:
|
||
;;
|
||
;; (add-to-list 'vc-handled-backends 'Git)
|
||
|
||
;;; Todo:
|
||
;; - check if more functions could use vc-git-command instead
|
||
;; of start-process.
|
||
;; - changelog generation
|
||
|
||
;; Implement the rest of the vc interface. See the comment at the
|
||
;; beginning of vc.el. The current status is:
