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 "]")))))
It's an opportunity to learn more lisp!
I do currently have a shell script using ripgrep & notmuch-tag, but felt it could be an interesting problem to solve within Emacs :)
