Ita Language for Visual Studio Code
Syntax highlighting, semantic themes, and snippets for the Ita programming language.
Ita ("stone" in ancient Tupi) is a strongly-typed, immutable-by-default, functional-first language that compiles to Dart Kernel (.dill) and runs on the Dart VM.
Features
Syntax Highlighting
Full TextMate grammar with 78 patterns across 27 categories, covering all Ita constructs:
- Types:
struct, class, enum, trait, actor
- Functional:
match, guard, where, pipe |>, compose >>
- Async:
async/await, stream/emit, spawn
- Error handling:
Result, Option, panic, try ?
- 35+ built-in namespaces:
Http, File, Json, Crypto, etc.
Semantic Themes
Two themes (dark and light) with 76 unique colors organized in 7 semantic families that teach language concepts through color:
