feat(resolution): tsconfig path aliases + re-export chain following (#130)
* feat(resolution): tsconfig path aliases + re-export chain following
Two related correctness improvements that unlock accurate import
resolution on modern JS/TS codebases.
1) tsconfig/jsconfig path aliases.
The resolver previously had a hard-coded list of common aliases
(@/, ~/, src/, app/) and ignored any project-defined paths from
tsconfig.json compilerOptions.paths — which means every import
through @components/Foo, @lib/utils, etc. on Vite/Next/Nuxt/Nest
projects silently failed to resolve. Adds src/resolution/path-
aliases.ts that reads tsconfig.json (and falls back to jsconfig.json),
honours baseUrl, supports the * wildcard, and respects the priority
order of multiple replacement targets per alias. JSONC tolerant
(strips comments + trailing commas, common in the wild). The new
ResolutionContext.getProjectAliases() lazily loads + caches the
result; resolveAliasedImport consults it before the legacy fallback
list.
Verified live on a synthetic project with @utils/* and @lib custom
aliases: both resolved to the correct files and produced edges,
unresolved_refs empty.
2) Re-export chain following.
`import { Foo } from './barrel'` where barrel.ts only re-exports
(`export { Foo } from './real'` or `export * from './real'`) used
to fail because the resolver only looked for declarations IN the
resolved file — it never followed the export chain to the actual
definition. Adds extractReExports() (named + wildcard + as-rename
forms), a per-file getReExports() context method, and a recursive
findExportedSymbol() helper with depth cap (8) and visited-set
cycle protection. resolveViaImport now uses it whenever the symbol
isn't directly declared in the imported file.
Verified live on a synthetic 3-hop chain (main → all.ts wildcard →
index.ts named → auth.ts declaration): signIn resolved correctly,
unresolved_refs empty.
Full test suite: 380 passed, 0 failed.
* fix(resolution): address reviewer findings — isExternalImport bypass, JSONC strings, comment stripping, optional context method
Five fixes from independent semantic review:
- isExternalImport now consults context.getProjectAliases() before
the bare-specifier heuristic. Without this, custom prefixes like
'@components/*' from tsconfig.paths were classified as npm and
resolveAliasedImport never even ran. Adds a context parameter
(optional, for backward compat with mock contexts).
- stripJsonc rewritten as a string-aware state machine. The previous
regex-only version corrupted any URL embedded in a JSON string
value ('https://cdn.example.com' lost everything after '//').
- extractReExports now strips JS line+block comments from content
before applying the regex, so a commented-out 'export { x } from
...' no longer creates a phantom re-export edge. New
stripJsComments helper preserves string literals (single, double,
template) so '//' inside a string stays intact.
- ResolutionContext.getProjectAliases() made optional so existing
mock contexts in __tests__/resolution.test.ts (which TypeScript
doesn't type-check because tsconfig excludes __tests__) don't
throw at runtime when resolveAliasedImport hits them. Caller
uses ?.
- Two new integration tests in __tests__/resolution.test.ts:
* Path-alias resolution with name-collision: two pickMe() in
different dirs, only the @utils-aliased one should be the
call target. Asserts via getCallers on each candidate node.
* No-tsconfig fallback: relative import still produces the call
edge.
Full test suite: 832 passed (was 380; the increase is from the
biomarkers + LLM hooks that ship via parent branches).
* fix(resolution): allow re-export rename chains past the pre-filter
The fast pre-filter in resolveOne() bails when no symbol with the
reference name exists project-wide, which is incompatible with the
new chain-following code: a renamed re-export (`import { login }
from './barrel'` where the barrel does `export { signIn as login }
from './auth'`) intentionally calls a name that has no project-wide
declaration. The chain finds the renamed upstream symbol — but only
if resolution is allowed to run.
Add an import-mapping escape so the pre-filter only bails when the
ref also doesn't match any local import. Adds two tests covering the
3-hop wildcard chain and the named-rename branch.

feat(extraction): instantiates + decorates graph edges (#134)
* feat(extraction): instantiates + decorates graph edges
Two new structural edges that fill gaps in the call graph for
modern JS/TS / Java / C# / Python / Kotlin codebases.
1) `instantiates` edges from `new Foo(...)`:
The bulk-extraction and visitFunctionBody dispatchers only
recognised `call_expression`; `new_expression` (and the equivalent
`object_creation_expression` / `instance_creation_expression` in
other grammars) was silently ignored. Adds INSTANTIATION_KINDS,
extractInstantiation(), and dispatch from BOTH the top-level
visitNode and the per-function-body walker. Children are still
descended so nested calls inside constructor args (`new Foo(bar())`)
get their own `calls` refs.
Output: a `bootstrap` function that does `new UserService(); new
UserController(svc)` now produces two `instantiates` edges to those
class nodes — previously zero edges.
2) `decorates` edges from `@Decorator` annotations:
Tree-sitter places decorator nodes BEFORE the symbol they apply to
in the AST, so the original walk-time dispatch saw the wrong
nodeStack head (file/class instead of class/method). Replaced with
extractDecoratorsFor(declNode, decoratedId) that runs from inside
extractClass / extractFunction / extractMethod after the symbol's
node id is known.
Looks for decorator nodes in two places:
- Direct named children of the declaration (method/property style)
- Preceding siblings in the parent (TypeScript class style:
@Foo class X {} parses as parent { decorator, class_decl })
Sibling check uses startIndex comparison rather than reference
identity — tree-sitter web bindings return fresh JS wrappers from
parent/namedChild navigation, so `===` is unreliable. Took a debug
session to spot this; flagging in the comment so the next reader
doesn't re-introduce the bug.
Output: a `@Controller` class decorator + `@Get` method decorator
on a NestJS-style controller now produce two `decorates` edges
(class→Controller, method→Get) with the correct source nodes.
Verified live on a synthetic NestJS-shape fixture; all 380
existing tests pass.
* fix(extraction): address reviewer findings — decorator boundary, generic constructors, property/field decorators, marker_annotation, tests
Five fixes from independent semantic review:
- extractDecoratorsFor sibling walk now iterates BACKWARD from the
declaration and stops at the first non-decorator/annotation
separator. Previous version walked forward up to declStart and
consumed every decorator-typed sibling — so two adjacent
decorated classes (`@A class Foo {} @B class Bar {}`) had `@A`
spuriously attributed to `Bar`.
- extractInstantiation strips the type-argument suffix from the
constructor field text. `new Map<K, V>()` was producing
referenceName 'Map<K, V>' (the constructor field is a generic_type
node) and resolution always failed.
- extractProperty and extractField now call extractDecoratorsFor
after their createNode calls. NestJS-style `@Inject() private
svc: Foo` and Java field annotations were being silently dropped.
- consider() in extractDecoratorsFor recognises 'marker_annotation'
in addition to 'decorator'/'annotation'. Java's tree-sitter grammar
emits marker_annotation for arg-less annotations like @Override
and @Deprecated; without this every Java marker annotation was
silently skipped.
- 6 new extraction tests covering: instantiates ref for new Foo(),
generic-type stripping (`new Container<string>()` -> 'Container'),
qualified-new keeps trailing identifier (`new ns.Foo()` -> 'Foo'),
decorates ref for @Foo class X {}, regression for adjacent
decorated classes (each gets its OWN decorator), decorates ref
for @Foo method().
Full test suite: 386 passed (was 380, +6 new extraction tests).
* feat(resolution): kind-aware scoring + Python instantiation promotion
Two follow-ups to the new instantiates/decorates ref kinds, surfaced
during review:
1) name-matcher previously only had a kind bonus for `calls`
(preferring function/method). When a class and a function share a
name across modules, an `instantiates` ref would tie or pick the
wrong candidate. Adds:
- `instantiates` → +25 for class/struct/interface
- `decorates` → +25 for function/method, +15 for class
(Python class decorators, Java annotation interfaces)
2) Python (and Ruby) have no `new` keyword — `Foo()` is the standard
instantiation syntax, indistinguishable from a function call at
extraction time. Resolution can tell the difference once the
target is known: when a `calls` ref resolves to a class/struct,
promote it to `instantiates`. Mirrors the existing extends→
implements promotion in createEdges.
Verified: 386 → 389 passing (+3 tests covering the kind biases and
the Python promotion).

fix: Prevent false cross-module edges in name-based resolution
Name matching was creating false `calls` edges between unrelated modules in monorepos because `findBestMatch()` had no concept of directory proximity — functions with common names (e.g. `navigate`) in different apps scored identically and resolved to whichever came first. Adds path proximity scoring (shared directory segments) so same-module candidates strongly win over cross-boundary ones, and lowers confidence for distant matches so import-based resolution takes precedence.
