Add pre/post hooks or git support

[thomasf]

I keep my packages/ dirs in local git repos for each emacs installation I use to be able to go back for troubleshooting or quickly backing out of temporarily broken packages.

Would be great to combine that with this mode in some way.

[rranelli]

pre and post update hooks are probably straightforward to implement.

Do you think those would be enough for your use case ?

[thomasf]

Yeah.,. really don't add them if no one else wants them, if no one else wants this I can just use advices.

[rranelli]

Alright. I will leave this open in the case someone finds the same need.

[andyleejordan]

This could be useful for me too. I have Git sub-modules for some packages where I'm tracking development versions, so I'd totally use this to auto-update them too.

[rranelli]

Ok, I will the before-update and after-update hooks when I find some time ;)

[andyleejordan]

Haha, sounds good :D

[rranelli]

Alright, done in 2e91e78a and 1c33c04.

@thomasf @andschwa Could you guys check if these are enough ?

Thanks !

@rranelli This works perfectly for me with some way over-engineered Lisp to update my submodule(s, I thought I had more and wrote it to handle a list of them):

(add-hook 'auto-package-update-after-hook
      (lambda ()
        (--each '(("magit" "git pull upstream next"))
          (async-shell-command
           (concat "cd " (f-expand (f-join "lisp" (car it)) user-emacs-directory)
               " && " (cadr it))))))
