Subject: 24.5; Wish: Customize as a general-purpose configuration facility
Date: Thu, 16 Jul 2015 20:18:04 +0200

Dear GNU Emacs maintainers,

the widget interface that Customize creates is tightly tied to
`Custom-mode'.  Yet, the same interface could be useful to any package
that requires users to perform some kind of complex configuration (for
example: configuring a software project before compiling).  Right now,
libraries either resort to asking questions (but this approach doesn't
scale), or require users to edit Lisp files (with the risk of making
mistakes).  Sure, there is the Widget library, but the interface that
has already been implemented for Customize offers a lot of functionality
(automatic creation of widgets according to the type of variables,
search, reverting of changes, etc.) and the ability to reuse all that
work would be no small gain.  Moreover, users would be interacting with
a familiar interface.

Thanks for your attention.

Best Regards.

Do you want something more than what is documented in this node:

    (info "(eieio) Customizing")

No, I don't.  EIEIO is not a renowned package -- the Emacs Lisp
Reference mentions it only once cursorily, and it seems that only CEDET
uses it -- hence I hadn't looked into it.

EIEIO Custom Mode could look more similar to Custom Mode, but I infer
that these modes were written independently, hence achieving a similar
*look and feel* could require too much refactoring.  Anyway, it seems
that the lambdas inside `eieio-custom-object-apply-reset' could be
extracted as commands, so that users could bind them to keys.

Thanks for your assistance.

In the same vein, you can look at assistant.el (part of Emacs and Gnus).
It tries to address exactly this need without any library dependencies
like EIEIO's Custom Mode. It uses the Customize widgets. It lacks
documentation and practical use cases, and hasn't been updated in a
while though.  So it really needs a maintainer IMHO.
