visit-source.el

grab a file visit-source.el, put it somewhere on load-path, bind to a key – I have it within ffap package:

(use-package ffap :ensure nil
  :config
  (require 'visit-source)
  ;;(setq ffap-file-finder #'visit-source)
  (setq ffap-file-finder #'find-file)
  :bind (("H-<return>" . visit-source)))

In any buffer put a point on a file-looking string and call {M-x visit-source RET} (or {H-<return>} for me).

File-looking string can be:

• a filename
• a filename with lines (as in exception or log output)

When I first find it on r/emacs comment, it was much simpler version and was intended as drop-in replacement for find-file. Then I added project awareness, so you can visit-source on a file Pavels-Emacs-Configuration-v3.org by filename, from anywhere in the project.

Initially I adopted visit-source instead of find-file {C-x C-f} but then switched to find-file-at-point that has a bit different semantics and kept visit-source at {H-RET} separately.

visit-source worked in most cases, but still had some rough edges, like didn't parse when path at point ends with dots, so text like ../Pavels-Emacs-Configuration-v3.org. didn't parse, so I had to manually end sentences with "../Pavels-Emacs-Configuration-v3.org file." or "../nv directory." Yesterday I bumped into the need to visit arbitrary Org Mode link. {C-c C-o} runs OS open on it, so log files were opening with TextEdit.app for me. Surely I can reconfigure it in macOS level to associate Emacs with log files (via UI?); but visit-source looks the way for it.

Given personal tooling reneissance, with Claude Code on <2026-05-06 Wed> I asked it to refactor the code - extract helper pure functions, implement fixes, support Org Mode links, get rid of trailing punctuation, add tests.

So meet visit-source v0.3.0 – visit-source.el!
