Subject: 30.1; describe-input-method does not respect help-window-select
Date: Wed, 30 Apr 2025 16:29:42 -0400

Hi folks,

It seems that describe-input-method does not respect
help-window-select. Here is a recipe:

1. Emacs -Q
2. Evaluate:

(setq help-window-select t)

3. C-h I japanese RET

Observe that the help window is not selected.

In contrast, if you do C-h v help-window-select RET, the help window is
selected.

Thanks!

I see now that the documentation for help-window-select says:

This option has effect if and only if the help window was created
by ‘with-help-window’.

So maybe this is not a bug per se.

Should we improve quail-help to use with-help-window?

Thanks!

Yes, if we want it to heed help-window-select, we should.

Patches welcome.  But please be careful and test the changes
thoroughly: AFAIR input-method help has several features thyat we
would not like to lose.

Thanks.

Sounds good. I will give it a try. I’ll mail back here if I run into problems.
