How to enable follow-mode for helm-grep-do-git-grep

[zw963]

Hi, i want to use helm builtin helm-grep-do-git-grep instead of not live maintained helm plugins helm-git-grep-at-point

but, i don't know how to enable follow-mode for this command in my emacs config.

For now, i have to C-c C-f switch follow-mode after i restart my emacs.

Thank you.

For all helm commands, not just *git-grep, add to your init file: (setq helm-follow-mode-persistent t) Then once you hit once C-c C-f in a specific source, you will have follow-mode enabled for this source forever until you hit again C-c C-f.

(setq helm-follow-mode-persistent t)

Yes, in fact, i set this to true, but, i still have to C-c C-f once since i first start emacs, because i don't know how to enable
following mode to helm-grep-do-git-grep directly in my config.

What i expected to is, enable follow-mode for helm-grep-do-git-grep after i start emacs immediately.

I guess this source is name helm-source-grep-git, but, i found it is nil when i try to retrieve this variable.

I try to enable it with:

(add-hook 'helm-before-initialize-hook
          (lambda () (helm-attrset 'follow t helm-source-grep-git)))

But this config even broken my helm config ...

You don't have to do this, please follow these steps: (setq helm-follow-mode-persistent t) ;; Eval it with C-x C-e. If you don't eval it it will take effect only in next emacs session (it is what is happening to you right now). Then launch helm-grep-do-git-grep somewhere and hit C-c C-f, that's all you don't have to do anything else. Restart emacs, launch helm-grep-do-git-grep somewhere you will see it have follow-mode enabled.

NO!

Of course.

Also, note that once follow-mode is enabled for your source, if you hit another time C-c C-f it will disable follow-mode but persistently, it will be disabled next time you start emacs.

Restart emacs, launch helm-grep-do-git-grep somewhere you will see it
have follow-mode enabled.

Yes, i find it works! thank you.

Though, i am curious, how helm can save my status cross emacs session.

ASAK, after i reboot emacs, all status should missing.

Does helm save status to a file in ~/.emacs.d/ folder?

Great.

In your custom file.
