Cannot start language server

[repomaa]

I installed the svelte-language-server package and tried running it both without arguments:

$> node_modules/.bin/svelteserver

and with --stdio

$> node_modules/.bin/svelteserver --stdio

In both cases nothing happens. The command just exits immediately without any output. Exit code is also 0.

I assume you're referring this

language-tools/packages/language-server/src/server.ts

Line 24 in d2e41cd

const connection = process.argv.includes('--stdio')

This never gets release to npm. You would have to build from source to have this feature

What are you trying to achieve?
If you want to use the extension, install it from the extension marketplace or from inside VSCode (it's called Svelte Beta).
If you want to participate in development of the extension, follow these instructions.

I’m trying to use it with the vim plugin ale. It supports language server checkers/linters.

The svelte-language-server npm package is actually from this repo. This repo right here is the newer version of it, but we don't have an official npm package yet (@orta is that something we would want to do later?). How to run it from the command line - we don't know. There is another extension for Atom who uses the npm package which does this:

startServerProcess () {
    return super.spawnChildNode([require.resolve('svelte-language-server/bin/server.js')], {
      stdio: [null, null, null, 'ipc']
    })
  }

Maybe you have more luck with that. But apart from that, we cannot help you right now.

Another (neo)vim user here excited about the recent developments! A stable CLI released to npm would be awesome. I recently migrated my setup to CoC and there’s a svelte extension for it.

There’s also an open issue which I assume will require something like this.

[dummdidumm]

Alright, I opened a new issue for the npm package topic.

To answer the original question: This is not doable for this repo right now, only for the old. For the old one: From what I saw in the other IDE plugins so far, the path/command to starting the server is node_modules/svelte-language-server/bin/server.js.

About the stdio support I mention before, you could refer to the original PR jamesbirtles/svelte-language-server#38 from origin repo. It's merged after the last release.

We'll see how the deploy works tonight, but this might then be fixed

[dummdidumm]

svelte-language-server package now refers to this repo and is up to date.

Could you try some of the suggested solutions and tell us if it works?

A CLI seems pretty easy to create if anyone wants to give it a shot: #68

The language-server is now regularly shipped 👍 and there's a svelte-check CLI
