Subject: 31.0.50; Add markdown-ts-mode support to eglot/eldoc
Date: Wed, 16 Apr 2025 21:07:48 -0300

Hi all,

I'm opening this as a feature request rather than a bug report.

Now that `markdown-ts-mode` is available on `master`, and with some
exciting developments on the horizon (see:
https://lists.gnu.org/archive/html/emacs-devel/2025-04/msg00581.html), I
wanted to propose a potential improvement to `eglot`.

Currently, I’ve been experimenting with a small hack to enable proper
highlighting and formatting in the eldoc buffer when using language
servers that return Markdown documentation. By explicitly setting the
eldoc buffer to `markdown-ts-mode`, the results are quite promising.

Instead of relying on this workaround, would it be possible to support
`markdown-ts-mode` (or optionally `gfm-view-mode`) within
`eglot--format-markup` directly? This could be an opt-in feature for
users who prefer either mode for viewing Markdown content.

It might still be a bit early, but I believe integrating this kind of
support would further enhance the experience that Eglot already
provides.

Thanks for considering!
