I agree to follow the code of conduct
I searched issues and couldn’t find anything (or linked relevant results below)
If applicable, I’ve added docs and tests

Description of changes

This migrates the extension to use remark-language-server which is introduced
in remarkjs/remark#924.

This basically reimplements the extension from scratch andrepurposes it.

Old behavior:

Format code using a custom command.

New behavior:

Use the same configuration as remark-cli
Register an actual formatter
Support ESM configurations
Support diagnostics
Support quick fixes

Closes #17
Closes #41
Closes #58
Closes #61

Thanks @remcohaszing!
It looks like CI is getting stuck at

npm ERR! Missing script: "clean"

👍 after build succeeds!

This uses esbuild to bundle and minify the extension.

It has also been renamed to lower case to be consistent with the rest of the unified ecosystem.

This is more about testing the language server can be loaded than about testing its functionality, as that’s tested upstream in unified-language-server.

ESBuild can’t process require statements which load NodeJS builtins, so the language server is built as a CJS module. It is able to use dynamic import() this way, so everything works fine this way (this is also tested).

The test file must be loadable by @vscode/test-electron, meaning it has to use CJS.

VSCode Extensions need to use CJS, but this is built using esbuild anyway.

@remcohaszing I see you sometimes pushing updates to dependencies. Are you treating this PR is ready to go? Because I’m waiting for the tests to turn green and I was under the impression that there are still some things being worked on?

remcohaszing · 2022-01-13T11:26:03Z

I was hoping that might automagically fix it, but it didn’t, not that I really expected that.

Previously the Windows build failed, but now even the Linux build fails. It used to work on Linux.

Manual testing shows the following error.

Unfortunately I also couldn’t easily get source maps to work for debugging. Changing line 11 in src/extension.js to const args = [require.resolve('remark-language-server'), '--stdio'] helps with debugging.

It would also help if someone can manually confirm it works on macOS or Windows. Especially Windows development setups are pretty alien to me. Can people just invoke node?

I also tried using LSP over node-ipc instead of stdio earlier. This caused issues. I think it disallows to use ESM.

I currently have limited time to look into this, but I do really want to finish this!

wooorm · 2022-01-27T08:42:21Z

ctx.asAbsolutePath seems to be in the right direction: https://github.com/angular/vscode-ng-language-service/blob/2deee1829a386f2f0981116378508b71ae974f3a/client/src/client.ts#L499-L514.

so ubuntu seems to work always, macOS is flakey, and windows fails always?

remcohaszing · 2022-01-27T08:59:49Z

Kind of but not quite? I see an Ubuntu build failing while typing this comment.

I think using the ipc transport might also make it a bit more stable.

This test doesn’t rely on any timeouts.

wooorm · 2022-07-12T19:31:06Z

Can you mention me again when this is in need of a review?

wooorm · 2022-07-13T20:14:21Z

We probably should also remove the lockfile, and clean other repo things, in further PRs, btw!

remcohaszing · 2022-07-13T20:29:10Z

Omg all checks have passed! 🎉

I agree we can do some more cleanups in other PRs. Let’s focus on this one first though. I’ll fix various quirks after this PR has been merged.

wooorm · 2022-07-13T20:45:36Z

Sweet, landed!
Let me know what your plans are, to first update some more things (?), and to release something?
