Release Notes
Added
ProjectQuery trait in cha-core — plugins now access cross-file data through a typed interface on AnalysisContext.project instead of host-side post-hoc string-matched filtering. 12 methods cover the project-level queries existing post-analysis passes need: is_called_externally, callers_of, function_home/function_by_name/class_home, is_third_party, workspace_crate_names, is_test_path, etc. WASM plugins also gain access via the project-query host import.ProjectQueryBulk trait extends ProjectQuery for in-process iteration (iter_models); not exposed to WASM.cha_core::is_test_path — public utility consolidating two duplicated implementations.- example-wasm
unused_helper smell — demonstrates project_query::callers_of callback.
Changed
- WIT bumped to
cha:plugin@0.3.0 (breaking) — adds project-query host import. External plugins compiled against 0.2.0 must rebuild.
large_api_surface C/C++ heuristics — .h/.hpp headers are now skipped (their 100% public surface is by design); .c/.cpp implementation files use a higher count threshold (30, configurable as c_max_exported_count) and the ratio gate is effectively off (configurable as c_max_exported_ratio). lvgl baseline: 393 → 34 findings (-91%).dead_code is now project-aware — uses ProjectQuery::is_called_externally to confirm cross-file usage; the per-file text search is just an early shortcut. The token-concat macro heuristic (#define ... ##) remains because parsers don't macro-expand. lvgl baseline: 67 → 6 findings (-91%).
Removed
Plugin::cross_file_aware_smells trait method — replaced by typed query through AnalysisContext.project.cha-cli::cross_file_filter module — the post-hoc string-matched filter is gone; plugins produce final findings using the typed trait.- 3 duplicated
workspace_crate_names impls + 3 duplicated is_third_party/is_external_leak impls + 2 duplicated is_test_path impls — all consolidated.
Added
- New
.cha.toml config keys for api_surface: max_exported_ratio, c_max_exported_count, c_max_exported_ratio, skip_c_headers. All language-aware defaults preserved.
