If you love Visual Studio Code or Neovim and you find the prevailing Scala extensions too cumbersome, give this a try:
Both plugins are powered by a lightweight language server:
Since 0.2 the plugins have become even easier to use. Indeed, the language server is now downloaded and launched automatically. No configuration is necessary for simple projects. External dependencies and compiler options can be provided in a scalavista.json file at the root of your project. No need to import any builds.
Disclaimer: This is a personal side project, which I started because I was unhappy with the existing solutions. It works well enough for me but please don’t expect industrial-strength. Feedback and contributions are most welcome!
