npm run ui fails on Fedora Silverblue 36 (Wayland)

[aral]

Running npm run ui (with emcc on my path), gives the following output:

> tree-sitter-svelte@0.10.1 ui
> tree-sitter build-wasm && tree-sitter web-ui

Started playground on: http://127.0.0.1:8000
F: X11 socket /tmp/.X11-unix/X0 does not exist in filesystem, trying to use abstract socket instead.

In the browser (tested on Firefox and Ungoogled Chromium), I get the following errors:

RuntimeError: abort(Assertion failed: undefined). Build with -s ASSERTIONS=1 for more info.

Wondering if this is a Wayland-related issue as the web ui appears to be attempting to do some sort of X11 forwarding?

Thanks for the issue. I will check on it and resolve it further.

Thanks, @Himujjal; appreciate it :)

Seem to be an issue with https://github.com/tree-sitter/tree-sitter/issues/1098

I will keep this issue meanwhile. Tree-sitter is not 1.0 software yet. Probably these edge cases don't work. When I last tried the ui part, it was working flawlessly.

@Himujjal Thanks for investigating it.

Closing this issue @aral as of now.

Lets meet again, when the aforementioned https://github.com/tree-sitter/tree-sitter/issues/1098 & https://github.com/tree-sitter/tree-sitter/issues/1829 issue is resolved.

By the way the generated WASM is already in the repo, You can check once.
