Kind regards,

I've just managed to make Emacs 29 work with serve-d using
use-package and eglot (which both come built-in on Emacs 29+).
If anyone is interested, I just downloaded a pre-built binary
from the serve-d Github releases page, then added this to my
init.el file:
```lisp
;; D
(use-package d-mode :ensure t
:init (with-eval-after-load 'eglot
(add-to-list 'eglot-server-programs
'(d-mode .
("~/programming/apps/serve-d")))))
```
This follows the eglot documentation's advice.
When you go do a D buffer, d-mode starts up automatically, but
not eglot... just hit "M-x eglot" to get serve-d assistance
(which will also work on other files you open in the same
project).
I found the eglot docs quite helpful:
https://joaotavora.github.io/eglot/#Setting-Up-LSP-Servers
Things that are working for me (so you can check if your setup is
working):
* eglot-format-buffer - formats the buffer
* minibuffer docs - as you point at code elements.
* code navigation - e.g. hit `s-.` to go to a definition,
including D stdlib.
* auto-completion - shows available symbols, even from
non-imported modules.
* flycheck - shows errors as you type, highlighting them in the
editor.
The auto-import functionality does not seem to work (it doesn't
automatically insert imports, despite the auto-completions saying
"auto-import ...". But apart from that, this is a very nice
environment to write D code!
I also added a [".dir-locals.el"
file](https://www.gnu.org/software/emacs/manual/html_node/emacs/Directory-Variables.html) on the root of my project with something like this (so that the formatter doesn't put 8 spaces on indentation! And "M-x compile" does the right thing):
```lisp
((nil . ((indent-tabs-mode . nil)
(tab-width . 4)))
(d-mode . ((compile-command . "dmd -L-ld_classic -run"))))
```
Hope that helps others as I had to spend some time trying to do
more advanced stuff when the setup that actually works is really
basic.
