Subject: bug#79157: [PATCH] Fix recursive load when 'calc-always-load-extensions' is set
Date: Sat, 2 Aug 2025 11:31:53 -0500

[Message part 1 (text/plain, inline)]

Hi folks,

The Calc setting calc-always-load-extensions leads to a recursive load
error if you set it in your init file before loading calc.el. (If you set it after
loading calc.el, e.g. via calc-settings-file, there is no recursive error, but
it also doesn’t load the extensions.)

To reproduce:

1. Emacs -Q
2. Eval: (setq calc-always-load-extensions t)
3. M-x calc RET

You should see a recursive load error.

This is due to this top-level stanza near the bottom of calc.el:

(when calc-always-load-extensions
  (require 'calc-ext)
  (calc-load-everything))

This can never work as written, since calc-ext.el requires calc.el.

I took a stab at correcting this by deleting this stanza and moving the
call to calc-load-everything inside calc-create-buffer. I’m not sure if
this is the best way, so feedback is welcome.

Thanks!
