Language-tools: Jetbrains support

[maraisr]

Is your feature request related to a problem? Please describe.
I can see there is an official plugin for vscode, but not the Jetbrains?

Describe the solution you'd like
I can see that https://github.com/tomblachut/svelte-intellij already has a plugin, but this doesnt work. The plugin has been marked as broken, so when you install it—it specifically asks to opt into beta code. That and, if i do there is no TypeScript support.

Describe alternatives you've considered
Moving to vscode... But that is a much bigger ask.

How important is this feature to you?
Extremely. So much so that I'd try find some Java developers to help me with this.

@maraisr
I share your mindset with this. I contacted JB plugin author and he promised, he will work on that, it was maybe 3-4 weeks before, offering him help too with tests, no response since that time. Btw. nowadays Kotlin is better option for JB plugins.

Collaborator from the language tools repo here: Sadly intellij does not support the language server protocol which the extension for VSCode is based on. So this is out of scope for us right now. As you said, your best chance right now is helping the author of the intellij plugin.

Yeah, it _may_ be easier for all folks involved to look into making a new plugin which explicitly uses the LSP from svelte-language-server - I imagine there must be existing patterns for this in the jet brains ecosystem

Hi,
Sorry please ignore the below, it was not quite working as expected..will post an update once I have it working...

hope this will help, but you can get intellij support by installing the intellij-lsp from here:
https://plugins.jetbrains.com/plugin/10209-lsp-support
then in command line run:
npm install -g svelte-language-server
then in intellij preferences for the language server add the settings as follows:
note, you can run which sveltesever to find the full path of the server and replace, screenshot shows path on my mac, you milage may vary depending on your OS version:

@lingster This solution actually works on my end, I didn't use raw command though, I used the executable option and added --stdio as an arg.

can confirm @lingster's solution works on Windows10 + WebStorm 2020.3.3 + LSP Support Plugin ! 👍

Autocomplete / typechecking behavior is (almost?) the same as with "Svelte for VSCode", but without syntax highlighting and some other features ( auto-import, component JSX attributes autocomplete ... etc. )
