auto-revert in VCS

auto-revert in VCS

[Andrea Crotti]

I would like to have auto-revert activated when I work with branches.
For example in git projects every time I change branch I have to revert
buffer manually to start working on the new branch.
So I wrote this in my conf:

--8<---------------cut here---------------start------------->8---
(require 'autorevert)
(setq auto-revert-check-vc-info t)
(setq auto-revert-interval 3) ;; this could be cpu consuming
(setq auto-revert-verbose t)

(setq global-auto-revert-mode t)
--8<---------------cut here---------------end--------------->8---

The problem is that emacs was sucking all my cpu power and that's not
nice...
I only need to enable auto-revert for files under revision control, and
only on files which I'm visiting in some buffers (and the buffer is
active), is that possible somehow?

That last setting is not recommended:

,----[ C-h v global-auto-revert-mode RET ]
| global-auto-revert-mode is a variable defined in `autorevert.el'.
| Its value is nil
|
|
| Documentation:
| Non-nil if Global-Auto-Revert mode is enabled.
| See the command `global-auto-revert-mode' for a description of this minor mode.
| Setting this variable directly does not take effect;
| either customize it (see the info node `Easy Customization')
| or call the function `global-auto-revert-mode'.
|
| You can customize this variable.

Call turn-on-auto-revert-mode in a find-file-hook function that checks
the result of (vc-backend buffer-file-name).

There is no such thing as an active/inactive buffer.
