using rgrep, ag, etc in folded org files?

[joakim]

Hello,

I would like to use ag search, or rgrep etc, to jump to matches in my
org files, and have the matched lines tree be unfolded.

- isearch works in a folded orgfile
- jumping with occur in a folded file works
- rgrep, ag, etc doesnt unfold the tree where the match is


I found this 6 year old thread discussing the same issue:
"org-mode, grep and folding issue".

The thread described some workarounds which used agenda search or
something like that. I would rather like to use helm-projectile though.

Is it possible?

Hi Joakim,

The function org-reveal needs to be run after the search is executed.
If you are using the built-in emacs rgrep (for example), I think you
need to add a function to next-error-hook.  Grep for “add-hook
'occur-mode-find-occurrence-hook” in org.el for inspiration.

(Arguably this hook function should be added to org-mode, if enough
people find it useful).

That would be brilliant.

Adding my +1 to this, particularly if that would expand stuff in ediff
merge situations also!

You might find this package useful (it's mine ;):

https://github.com/alphapapa/helm-org-rifle

Or you can install it from MELPA.

I have plans to look into using external tools to find matches someday.
git grep seems like the most promising, but maybe ag or agrep could work
too.  In the meantime, you may find the existing functionality useful.
It wouldn't be hard to customize it slightly to do what you want,
although you might like the feature to open selected subtrees in
indirect buffers.  Please feel free to give feedback on the tracker.  :)
