Regex Find in files (non-interactive) (alien.top)

Hi there,

I use orgmode links extensively. In particular, I have hundreds (our thousands) of links to emails (in notmuch). I would very much like to add a tag to any email that is being referenced from org.

So, what I need to do first is be able to find all matches of a regular expression in all my org files. Non-interactively.

I have been playing around with xref-matches-in-directory but that would not cover when multiple emails are mentioned in the same line...

I have been looking and looking but everything I find missed the non-interactive part.

So: What is the function to "search for this REGEX in FILES in DIR and return the first capture group"? (the regex has a capture group for the msgid)

The regex:

  (rx-to-string
   (rx "notmuch:id:"
       (group (1+ (not "]")))))

  • dired open needed dir
  • M-x grep-find (regexp)

Comes to my mind
