  • I LOVE Rust's exception handling

    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.
  • Kotlin is tightly linked to IntelliJ and that's a risk

    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)
  • What are best plugins for C++, Java, Kotlin, Python, & LaTex

    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!

  • Idea: Jetbrains Fleet's Code Engine as an LSP?
    4 projects | /r/neovim | 15 Oct 2022
    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.

  • Why LSP?
    14 projects | news.ycombinator.com | 25 Apr 2022
    Tangentially related: If a talented folks out there could please help out with (to the best of my knowledge) the only LSP for Kotlin out there[0], that would be amazing!

    I'm really attracted to Kotlin as a language[1], but, last I checked, IntelliJ is the only way to get great tooling for Kotlin, which is a show stopper for me since I've invested a lot into my neovim config.

    [1] What attracts me to Kotlin is that it is statically typed, with a relatively expressive type system, great type inference, not verbose. Rust fulfills all of these, but sometimes I'd like to avoid thinking about borrow-checking and managing life times all together, and, Kotlin projects are much more likely to get contributors since it's an easier language to get into.

    What you said would make sense, except they do build a plugin for Eclipse.

    Better options would be any language where the stewards are not trying to extract money from you by forcing your IDE choice. Or where they view fostering community good will as being in their best interest. Ex. MS offers an official LS rather than saying "we don't support other IDEs because Visual Studio licenses."

    There's lots of choices here for compile to JS languages:

    Does the LSP implementation [1] linked by the JetBrains employee in that thread not work? It pushed a new minor version release a little over a week ago.

    It seems pretty reasonable to me for them to not pay employee salaries to build a plugin for a competing product, especially when they already provide a comprehensive IDE solution available for free (in both senses). What other companies are doing that? I don't mean that as a challenge. I'd love to know what the better options are.
