  • I Think It's Time to Give Nix a Chance
    7 projects | news.ycombinator.com | 26 May 2025
    In most cases is enough to have emacs installed as part of OS with all required general cli tools and then open project specific shell with all project dev dependencies like compilers and libs.

    However is some cases when it could be little more tricky, for instance I'm using LSP for Scala (https://scalameta.org/metals/) which on start trying to automatically detect JDK version for project from environment. So if my project depends on JDK 11 it might required for me manually start LSP from nix-shell to force it use right JVM version.

    With Rust is in someway similar, I need to bring some shell with 'rust up' setup so it could install everything for rust-analyzer then emacs can use it.

    Regardless emacs itself is few options to manage emacs packages in nix way but for me it not really gives anything so I just use it as on any other OS.

  • Tmux, NeoVim, etc. to write pure Kotlin code?
    2 projects | /r/Kotlin | 30 Apr 2023
    You might want to look at Scala, they have proper LSP support with metals which means you can write your code in vscode, neovim, emacs, or even fleet (the new jetbrains text editor).

    Please write in the comments if you know of any language servers I should test it with. Currently I tested only metals and rust-analyzer.

    Bazel support in Metals. I didn't spend all that time figuring out and adjusting Emacs/Spacemacs and making my workflow (almost) mouse-free just to scrap my config and switch to IDEA's rodent infested ways.

    There is one small issue involving code completion returning inappropriate completions in some cases; https://github.com/scalameta/metals/pull/4414 will fix it, once it's included in a release. Perhaps that's the PR you saw?
  • Scala Isn't Fun Anymore

    It is, by quite a bit.

    While the "Scala IDE" project is dead for all practical purposes, IntelliJ IDEA's Scala plugin is actually pretty amazing. There's also a VisualStudio plugin that does pretty much the same and is advancing by leaps and bounds. There are also interconnecting projects that provide i.e. language server or build server that are reused by other projects. It's pretty modular. Metals (https://scalameta.org/metals/) is amazing.

    In general the language has become a wee bit faster to build, there was good progress with build times during the 2.12/2.13 cycles.

    With Scala3 the language got a bit simpler; concepts that were implemented explicitly using (hehe) implicits got their own keywords and a lot of the opinionated boilercode that cause a lot of debates is now generated during complication and hidden. A lot of "standardization" has occurred.
