Subject: 28.2; grep library not autoloading
Date: Wed, 15 Oct 2025 08:49:01 -0400

Using this line in the init file:
  (grep-apply-setting 'grep-command '"grep -d skip -HIn  -i ")

causes:
Debugger entered--Lisp error: (void-function grep-apply-setting)
  (grep-apply-setting 'grep-command '"grep -d skip -HIn  -i ")
  load-with-code-conversion("/home/reilly/.emacs" "/home/reilly/.emacs" t t)
  load("~/.emacs" noerror nomessage)
  startup--load-user-init-file(#f(compiled-function () #<bytecode 0x1f41bc44be3cf854>) #f(compiled-function () #<bytecode -0x1f3c686ddc0cdc35>) t)
  command-line()
  normal-top-level()

adding:
   (load-library "grep")

above the call to grep-apply-setting solves the problem

Thanks.

But why did you expect grep-apply-setting to be autoloaded?  We don't
autoload every public function in every package, so sometimes you need
to load the package "by hand" before you can use its functions.

I don't see a bug here.

That's impractical, sorry.  It will bloat the doc strings of many
functions.  The default is that functions which are not commands are
not autoloaded, so a package should be loaded before using any of the.
You need to get used to this default.

No further comments within 2 weeks, so I'm now closing this non-bug.
