Adds CI workflow (build + test matrix across Node 18/20/22 and ubuntu/macos/windows) and release workflow for publishing to npm on version tags. Uses node_modules caching with native rebuild strategy to avoid re-downloading dependencies on each run.
…e test expectations
Root cause: tree-sitter grammar native bindings for Swift and Dart are
incompatible with tree-sitter 0.22.4 on macOS arm64 (Apple Silicon,
macOS 26.2, Node.js v22.22.0).
Swift (tree-sitter-swift 0.6.0):
- The npm package fails to install entirely — `require('tree-sitter-swift')`
throws MODULE_NOT_FOUND. There is no prebuilt binary for this platform
and the source build fails. `loadGrammar()` correctly returned null,
but 8 tests still ran unconditionally and failed.
Dart (@sengac/tree-sitter-dart 1.1.6):
- The npm package installs and `require()` succeeds, but the grammar
object has an incompatible ABI with tree-sitter 0.22.4.
`parser.setLanguage(dart)` crashes with "Cannot read properties of
undefined (reading 'length')" inside tree-sitter's internal
`initializeLanguageNodeClasses` function. This is a two-stage failure:
`loadGrammar()` returned non-null (require worked), but `getParser()`
threw an uncaught exception at `setLanguage()`. The grammar was likely
built against a different tree-sitter ABI version.
Source fix (src/extraction/grammars.ts):
- Wrap `parser.setLanguage()` in try/catch inside `getParser()` so
ABI-incompatible grammars degrade gracefully instead of crashing
- Change `isLanguageSupported()` and `getSupportedLanguages()` to call
`getParser()` (validates full ABI compatibility) instead of
`loadGrammar()` (only checks if require succeeds)
Test fixes:
- Skip Swift/Dart test blocks via `describe.skipIf(!isLanguageSupported())`
so they are skipped on platforms where grammars are unavailable
- Remove hardcoded swift/dart from "supported languages" assertion since
availability is platform-dependent
- Fix schema version test: expected 1 but schema is now version 2 after
the v2 migration was added
- Fix DB tests: pass file path (path.join(testDir, 'test.db')) not bare
directory to DatabaseConnection.initialize() — better-sqlite3 cannot
open a directory as a database file
- Fix DB tests: call db.getDb() not db.getDatabase() — the latter method
does not exist on DatabaseConnection
- Fix truncation tests: manually set MAX_OUTPUT_LENGTH on Object.create'd
handler since constructor is bypassed and class field initializers
never run
… paths - Add skipIf guards for Kotlin extraction and import tests (same as Swift/Dart) since the grammar may not load on all platforms - Remove Kotlin from always-expected language list - Normalize path separators in resolveRelativeImport for Windows compat
- Rename vitest.config.ts to vitest.config.mts so Vite loads via ESM instead of the deprecated CJS API - Add @vitest/coverage-v8 dev dependency for the v8 coverage provider - Run tests with --coverage on the ubuntu/Node-22 CI cell
