The next release of Racket integrates the template form with the syntax form, which breaks some code in this package. The patch here: https://github.com/jeapostrophe/racket-langserver/commit/592220137c828724053ec57e7051ae541818a305.patch should fix things.

Leaving this here in case someone tries out the code. Should get fixed tomorrow.

On linux, due to the (recursive) dependencies on gui-lib, racket-langserver cannot run without a running X11 server. I believe the responsible dependencies are, besides gui-lib itself, drracket-tools-lib, which can be easily refactored into a headless component for racket-langserver, based on my experimentation... and racket-doc, which cannot. Since I've never used racket I'm not entirely sure what that racket-doc is doing; maybe it's not so hard to fix that issue as well.

Anyways, here's what happens if you try without X installed:

Welcome to Racket v7.8.
> (require racket-langserver)
; ffi-lib: couldn't open "libgdk-x11-2.0.so.0" (libgdk-x11-2.0.so.0: cannot
;   open shared object file: No such file or directory) [,bt for context]

With X installed but not running:

Welcome to Racket v7.8.
> (require racket-langserver)
Unable to init server: Could not connect: Connection refused
; Gtk initialization failed for display ":0" [,bt for context]

For completeness, with GTK installed and a non-X backend running there's also an error loading libX11.

Since this info was surprising to some people: Yes, there's a point to running a language server on a headless server: not only for TUI text editors, but even for GUI ones like VS Code Remote. And for what it's worth, I've not run into any other language servers which require X.

Requires the client to use a custom tokenizer. The current client implementation of racket/colorize applies decorations manually which prevents the document highlight request from being triggered.

I'd like to explore the use of this lsp server while playing on a toy racket based project

How do I install it ?

Do I need to require it from within the code of my project ?

Do I need to use raco in any way ?

And after installation, how do I connect my lsp client to the server ?

Thanks

Hey, I'd love to help you in some way. I don't have a lot of experience with Racket, but I'm sure I'd be able to do something given enough time. Is there any first issue you would recommend tackling?

Hi @dvc94ch.

I am an admin on the theia-ide GitHub organization. Most of the repos here have moved to Eclipse Foundation organizations. I am doing a cleanup pass. Can you confirm if this repo is still useful and should be kept? Else I would archive it.

Please let me know.

I think others will be interested and the topic will help them find it.
