New CodeMirror 6 language packages for Kotlin and Swift

v6
1

Hi everyone!

I’ve recently created two new language packages for CodeMirror 6:

  • @fazelstudio/codemirror-lang-kotlin — Kotlin language support

  • @fazelstudio/codemirror-lang-swift — Swift language support

Both packages are built with Lezer and provide parsing and syntax highlighting designed for CodeMirror 6.

Kotlin

@fazelstudio/codemirror-lang-kotlin supports Kotlin (.kt, .kts), including:

  • Classes, interfaces, objects, sealed/data classes

  • Functions, extension functions, and infix functions

  • Lambdas and when expressions

  • Null-safety operators

  • String templates

  • Ranges and generics

  • Annotations

  • KDoc comments

Repository:

Swift

@fazelstudio/codemirror-lang-swift supports Swift (.swift), including:

  • Classes, structs, enums, protocols, extensions, and actors

  • Generics and where clauses

  • Functions with async/throws

  • Closures and trailing closure syntax

  • Optionals and optional chaining

  • Pattern matching and switch

  • String interpolation and raw/multiline strings

  • Property wrappers and attributes

  • Custom operators

  • Swift documentation comments

Repository:

Both packages are released under the MIT license.

I’d love to hear feedback from the CodeMirror community, especially regarding grammar coverage, edge cases, and areas where the language support could be improved.

Thanks!

Wonderful. I’ve linked them from the community extension list on the website.
