Adds support for Dart and Liquid languages with tree-sitter parsing.
Improves accuracy of code symbol extraction for existing languages.
Indexes project files to enhance code navigation features.
Migrates build system to facilitate code contributions.
Removes git hook functionality.
Integrates Sentry for error tracking and reporting.
Enhances project initialization and configuration loading.
Extend extraction to index two additional categories of symbols
that were previously invisible:
1. Type aliases (e.g. `export type X = ...` in TypeScript,
`type X` in Go, `type X = ...` in Rust, `typealias X` in Swift,
`type_alias` in Kotlin). Adds `typeAliasTypes` to the
LanguageExtractor interface with values for all 13 languages.
2. Exported variable declarations that aren't functions, including:
- Zustand stores: `export const useX = create(...)`
- XState machines: `export const xMachine = createMachine(...)`
- Zod schemas: `export const schema = z.object(...)`
- Config objects: `export const config = { ... }`
- Constants: `export const MAX = 3`
- Arrays: `export const NAMES = [...] as const`
The extractExportedVariables() method is called when visiting
export_statement nodes. It skips variable_declarator values that
are already handled by functionTypes (arrow_function,
function_expression) to avoid duplicate extraction.
Adds 11 new test cases (59 total extraction tests, 215 total).
Tested on production monorepo: nodes increased from 958 to 1,172
(+22%), with 109 new variable nodes and 105 new type_alias nodes.
Only 4 files remain at 0 nodes — all are re-export barrels or
ambient declaration files with no extractable symbols.
Arrow functions and function expressions assigned to variables
(e.g. `export const useAuth = () => { ... }`) were not being indexed
because the arrow_function AST node has no `name` field — the name
lives on the parent variable_declarator node.
Additionally, `isExported()` for TypeScript and JavaScript extractors
only checked 10 characters back from the node's start position, which
missed `export` for deeply nested nodes like arrow functions inside
variable declarations inside export statements.
Changes:
- extractFunction(): When an arrow_function or function_expression
resolves to '<anonymous>', look up the parent variable_declarator
for the name before skipping.
- isExported() (TS + JS): Walk the parent chain to find an
export_statement ancestor instead of substring matching.
- Add 6 test cases covering arrow function exports, function
expression exports, non-exported arrow functions, anonymous
arrow functions, multiple exports, and JavaScript files.
Tested on a real monorepo (238 files): node count increased from
779 to 958 (+23%), with 94 new nodes in packages/ that previously
had 0 coverage.
- Add evaluation test suite with TypeScript and Python fixtures
- Fix MCP server to defer CodeGraph init until rootUri received
- Fix call edge extraction by calling resolveReferences() after indexAll/sync
- Fix glob matching for root-level files (e.g., **/*.py now matches auth.py)
- Fix duplicate node extraction for methods inside classes
- Update context tests to use buildContext for semantic search + graph traversal
- Export unused formatter functions to fix build
Evaluation results:
- TypeScript: 96% precision, 79% recall, 85% F1
- Python: 99% precision, 80% recall, 85% F1
