Copy the name of the current file (C-x C-j C-0 w) 2. M-x pdb RET yank RET (possibly after deleting previous file name) This seems like a good place to introduce a "future history" operation. The attached patch does so, via a new optional argument to gud-query-cmdline. The above then simplifies to M-x pdb RET M-n RET. Existing behavior is unchanged. I added the same feature to other gdb commands for which it seemed to make sense (perldb, guiler). Feedback or other suggestions would be welcome. --=-=-= Content-Type: text/x-patch Content-Disposition: attachment; filename=0001-Add-forward-history-support-for-some-debuggers.patch >From 81382b69b83298d5bc098cc49f373d57a0909b42 Mon Sep 17 00:00:00 2001 From: Paul Nelson Date: Mon, 21 Apr 2025 22:14:53 +0200 Subject: [PATCH] Add "forward history" support for some debuggers * lisp/progmodes/gud.el (gud-query-cmdline): Add an optional default-list parameter to allow passing a list of "forward history" suggestions to the minibuffer.
