Parser feature matrix

Parser feature matrix

Source of truth

• Parser module scope notes: crates/vox-compiler/src/parser/mod.rs
• Parser descent implementation: crates/vox-compiler/src/parser/descent/

Covered in canonical parser

• fn, pub fn
• type, pub type
• import
• component (UI component declaration; emits React/TSX)
• @endpoint(kind: server|query|mutation)
• @loading
• @table, @index
• @mcp.tool
• @test
• @v0
• actor, workflow, activity
• HTTP route declarations (http get/post/put/delete)
• routes { } (router shim generation)
• JSX tags and expressions
• Expression operators including pipeline (|>)

Retired (hard parser error)

• @island — retired 2026-05-03; use component instead
• @server, @query, @mutation — retired; use @endpoint(kind: server|query|mutation) instead

Explicitly out of parser scope (current)

• @page
• @partial
• @theme
• @layout
• @i18n
• @schema
• @action

Implications

• Out-of-scope declarations increase lowering/codegen coupling and can create parser/docs drift.
• Roadmap target is to pull these into canonical parser/typed-HIR coverage to reduce cross-stage boilerplate.

Near-term verification

• Keep parser tests aligned with this matrix.
• Fail CI when docs and parser scope diverge for declared feature support.
