codemap-typescript 0.4.0

TypeScript indexer plugin for CodeMap (https://github.com/qxbyte/codemap)

codemap-typescript

A TypeScript / TSX indexer for CodeMap, distributed as an independent PyPI package.

What this package proves

Adding a new language to CodeMap doesn't require touching the main repository. This package implements the codemap.indexers.base.Indexer Protocol against *.ts / *.tsx files and registers through the codemap.indexers entry-point group. Once installed it appears in codemap doctor next to the built-in indexers, on completely equal footing (ADR-004 + ADR-L001).

$ pip install codemap-typescript
$ codemap doctor

codemap.indexers.disabled: ["typescript"] in .codemap/config.yaml turns it off without uninstalling.

What it captures

Backed by tree-sitter-typescript. Single-file, no cross-file type inference (MVP):

AST node	Symbol kind	SymbolID descriptor
function_declaration	function	<path>/name().
class_declaration	class	<path>/Cls#
interface_declaration	interface	<path>/Cls#
method_definition (inside class)	method	<path>/Cls#name().
lexical_declaration (top-level const/let)	variable	<path>/Name.

Edges:

• import_statement / import_from_clause → imports to a synthetic module symbol (consumed by the same bridges the Python indexer drives).

The matcher is intentionally lean — class inheritance, generic constraints, and decorators are not yet captured. The point is that they can be: a v0.2.0 PR to this repository is enough to extend coverage, the main CodeMap repository stays untouched.

SymbolID encoding

Tests

pip install -e ".[dev]"
pytest

Limits / next steps

• No cross-file import resolution. The main python_cross_module bridge has a sibling for Python; a typescript_cross_module bridge could be added in a future release.
• No JSX-specific patterns (component declarations) yet.
• interface_declaration is captured as class kind — CodeMap's symbol schema doesn't yet have a distinct interface kind, see design §3.3.
