Adds ArkTS (.ets, HarmonyOS/OpenHarmony) as a first-class language:
full TypeScript-grade extraction via the harmony-contrib tree-sitter
grammar (MIT, vendored byte-identical from the tree-sitter-arkts 0.2.0
npm tarball), plus the ArkUI constructs that make HarmonyOS apps
traceable:
- @Component/@ComponentV2 structs with decorators from both grammar
positions; members extract as class members with qualified names.
- build() component trees: child instantiation edges via
arkui_component_expression, no synthesizer needed.
- Attribute chains emitted dot-prefixed and resolved ONLY against
@Extend/@Styles/@AnimatableExtend/@Builder helpers (unique-or-drop) —
bare-name fallthrough produced 36,840 wrong edges (17% of calls) on
the OpenHarmony samples monorepo. All four grammar chain shapes
handled, including the detached-chain forms.
- .onClick(this.handler) method-reference bindings.
- ohpm workspace modules: bare imports follow oh-package.json5 file:
deps (ambiguous names dropped), honoring each module's main entry —
which also lets .ts consumers resolve .ets modules.
- ArkUI dynamic-dispatch bridges, all provenance:'heuristic' with
wiring-site metadata: assignment-gated state->build() re-render
(V1 @State family + V2 @Local/@Provider/@Consumer),
@ohos.events.emitter emit->subscriber pairing on static event keys
(numeric ids same-file, named constants same-module, fan-out capped),
and router.pushUrl literal urls -> the target page's @Entry struct.
- $r/$rawfile resource intrinsics treated as built-ins; arkts joins the
web language family, value-reference edges, re-export chase, and the
other TS-applicable gates.
Also ships a language-agnostic index-completeness guard: indexAll
stamps index_state (indexing -> complete/partial/failed), reconciles
discovered vs accounted files (a loaded run silently dropped 37 files),
and codegraph status surfaces truncated/partial indexes in human and
--json output.
Validated on HarmoneyOpenEye (82 files), CoolMallArkTS (528, modular
ohpm + ArkUI V2), and openharmony/applications_app_samples (11,693
files, 202,890 nodes stable across re-index, attribute false-positive
audit 36,840 -> 588 residual all-plausible). Supersedes PRs #656 and
#988 with credit — both informed this implementation.
