Subject: 30.0.50; Android: Single key input doesn’t work
 in some situations
Date: Fri, 18 Aug 2023 19:36:32 +0200

In some cases, minibuffer prompts expecting a single key response don't
work.  I don't know whether it's actually Android specific but I've
observed it there.

I have two reproducible examples when this happens:

1. In Dired, when trying to copy a file (using `C' key) to another file
   that already exists, Dired asks for confirmation with the "yn!q"
   prompt.  It's possible to type multiple characters into the prompt,
   the typed characters appear there, but nothing else happens.  I have
   to use C-g to quit.  Instead, the prompt should react to the first
   typed character.

2. When running `M-x org-drill' on an org-drill file (org-drill is
   available from MELPA and
   https://gitlab.com/phillord/org-drill#demonstration describes an easy
   way to try it), one can normally type digits 1-5 to proceed with the
   cards.  Instead, the prompt doesn't react to keys at all and when I
   click to the primary buffer, the typed characters are inserted there.
   Both is wrong and doesn't happen in (non-Android) Emacs 29.1.

Thanks, both of these issues should be fixed soon.  They're particular
to the Android port, more specifically its input method text conversion
features.

Is there anything more to do here, or should this be closed?

Nothing other than waiting for a reply from Milan.

OK.  Milan, are you still seeing this problem?

Oh, thanks.  This is because Org Drill doesn't take measures to disable
text conversion (a mechanism whereby input methods insert text directly
within buffers) within Org buffers it manages, and consequently cannot
receive text typed from the keyboard as key events.

Phillip, would you please look into this?  As a rule of thumb,
disabling text conversion requires no more than:

  (setq-local text-conversion-style nil)
