intellij-lsp-server VS KotlinLanguageServer

I once had the idea of implementing an LSP server by embedding it as an IntelliJ plugin and backgrounding the IDE while doing the actual coding in Emacs.

It kind of worked, but once I stopped needing to use Java for my job it became too much of a hassle to flesh out.

The LSP means every single language server has to reinvent the wheel again and again.

It’d have been much more useful to build bindings for IDEA plugins so they could be integrated into arbitrary editors, especially as the IDEA plugins for most languages even after several years of LSP development are still superior.

All in all it’s like the whole JVM vs. WASM, Java vs Electron story again, with someone deciding to reinvent the wheel but worse.

There’s even bindings like https://github.com/Ruin0x11/intellij-lsp-server or https://plugins.jetbrains.com/plugin/10209-lsp-support to glue it all back together.

It’d have been much simpler to reuse an existing ecosystem from the start.

There's a community-made one, but of course as much effort as has been put into it it's not as featureful as JetBrains's own stuff.

Kotlin is probably the worst case for Neovim. While there is a language server for Kotlin, it's not very advanced and does not look like it's actively developed.

Hi, if you are going to do Kotlin the easiest choice is android studio with Kotlin plugin. Using Vscode is more tricky because Jetbrains does not want to support lsp for Kotlin so you only have https://github.com/fwcd/kotlin-language-server available to write Kotlin on Vscode.

Kotlin Language Server puts a warning on this code, because the bar inside the lambda shadows the function argument bar. Flow typing solves this problem by eliminating the need to redefine bar as a new non-nullable variable in the branch where we've verified it's non-nullable.

You want to change something about that? Go and help over at the kotin lsp server. It's maintained, and welcomes contributions. I sometimes use it in my day job (writing Kotlin backend code)

There is https://github.com/fwcd/kotlin-language-server, but I wouldn't expect something more official from a company that refuse to support LSP in their IDEs. JetBrains is the Apple of the IDE world.

Oddly enough, we use mostly the same languages. However, I would advise against using neovim with Kotlin: its language server has an excessive memory usage and its debugger is cumbersome with neovim (I haven't managed to get it working, and currently it also lacks an entry in nvim-dap's wiki).

I'll bring up the Kotlin LSP[0] every time I see Kotlin on HN because I really hope the LSP takes off (which would make it viable to use Kotlin with a non-IntelliJ editor).

Kotlin as a language looks really cool, but I don't want to give up terminal-based, modal editing (which I'd have to in order to use IntelliJ).

Along those lines, I once tried diving into using Gradle outside IntelliJ, and I couldn't find any good resources to help with that. If folks have hints/links-to-blog-posts with regards to that as well, that'd be great!

I've tried [this Kotlin LSP](https://github.com/fwcd/kotlin-language-server) and it isn't perfect. It's not complete, but it does some of the basic things.

I've downloaded kotlin language server from here: https://github.com/fwcd/kotlin-language-server
