How to find out where the message comes from?

Question

I'm trying to use Espanso in Emacs GUI. But nothing expands and Emacs echoes the message: "Beginning of buffer". The same snippet works everywhere except Emacs. I want to know where the message comes from and why Espanso or any other text expanders does not work in Emacs. It does work with emacs -q. I'm using Emacs Mac port with spacemacs.

Since it works with emacs -q, the fault is with your init file. Bisect it to find out what the problem is. — NickD, Jan 17 '23 at 12:59
@NickD The problem is that I use spacemacs, it has tons of settings. — Tokubara, Jan 17 '23 at 23:38

Use debug-on-message to enter the debugger and show a traceback when a message is shown which matches the regex it is set to:

(setq debug-on-message "Beginning of buffer")

To apply this to your init.el file, put the above in or close to its beginning (or if necessary in early-init.el) and restart Emacs. It might also work, but not necessarily so, by just running the code above and then evaluating the whole init.el file using eval-buffer.

That's really useful. Thanks for sharing. – g-gundam Jan 18 '23 at 14:57 — g-gundam, Jan 18 '23 at 14:57
