Release Notes
Added
- Plugin AST Query API — WASM plugins can now execute tree-sitter queries against the current file's AST via the
tree-query host import interface (run-query, run-queries, node-at, nodes-in-range). Enables plugins to do custom structural pattern matching without reimplementing parsing.
file-role enum in analysis-input — host infers whether a file is source, test, doc, config, or generated from its path, allowing plugins to apply differential detection strategies.- SourceModel enrichment —
analysis-input now includes comments, type-aliases, parameter-names, switch-arm-values, and is-module-decl fields previously only available to internal plugins.
parse_file_full() in cha-parser — returns ParseResult carrying model + tree-sitter Tree + Language for downstream use by WASM host callbacks.
Changed
- WIT bumped to
cha:plugin@0.2.0 — breaking change: plugins compiled against 0.1.0 must be recompiled. No behavioral change for existing internal plugins.
