Syntax highlighting for .ei files (source.eiwa TextMate grammar):
composition type system (type, contract, skill, first-class enum),
object/lib/test blocks, lambda-style for, string interpolation
($var, ${expr}), annotations, union types (Int | Null), of map pairs
Bracket matching and auto-closing pairs
Comment toggling (// and /* */)
Indentation rules and /** */ doc-comment continuation on Enter
Relationship with tree-sitter-eiwa
VSCode highlights via TextMate grammars, not tree-sitter, so this extension
ships its own syntaxes/eiwa.tmLanguage.json. It is kept in sync with the
canonical tree-sitter-eiwa grammar
(which powers the Zed extension)
by porting queries/highlights.scm scopes and grammar.js keywords.
Installing (dev)
