Overview

Package indexer orchestrates source code extraction and graph indexing.

The indexer walks repository files, dispatches them to the appropriate language-specific Extractor, stores the resulting nodes and edges, computes Merkle snapshots, and runs cross-repo edge resolution. It supports incremental re-indexing by skipping files whose content hash has not changed.

Key components:

  • Indexer: top-level orchestrator (indexer.go)
  • ExtractorRegistry: dispatches files to the first matching extractor (this file)
  • parallelExtract: worker pool for concurrent file extraction (worker.go)

Types

type ExtractorRegistry 

type ExtractorRegistry struct {
	// contains filtered or unexported fields
}

ExtractorRegistry maintains an ordered list of registered extractors and dispatches files to the first extractor whose CanHandle returns true. Extractors are checked in registration order, so more specific extractors should be registered before generic ones.

func NewExtractorRegistry 

func NewExtractorRegistry() *ExtractorRegistry

NewExtractorRegistry creates an empty ExtractorRegistry.

func (*ExtractorRegistry) FindAllExtractors 

func (r *ExtractorRegistry) FindAllExtractors(path string) []types.Extractor

FindAllExtractors returns all registered extractors that can handle the given file path. This enables multi-extractor dispatch: a .go file can be processed by both the Go extractor (functions, types) and the event extractor (Kafka/NATS patterns).

func (*ExtractorRegistry) FindExtractor 

func (r *ExtractorRegistry) FindExtractor(path string) types.Extractor

FindExtractor returns the first registered extractor that can handle the given file path, or nil if none matches.

func (*ExtractorRegistry) Register 

func (r *ExtractorRegistry) Register(ext types.Extractor)

Register adds an extractor to the registry.

type Indexer 

type Indexer struct {
	Concurrency int // number of parallel extraction workers; 0 means use runtime.GOMAXPROCS
	// contains filtered or unexported fields
}

Indexer orchestrates extractors to index a repository's source code into the knowledge graph. It manages the full lifecycle: file discovery, content-based change detection, extraction dispatch, batch storage, snapshot computation, edge event recording, and cross-repo resolution.

func NewIndexer 

func NewIndexer(store types.GraphStore, snapshot SnapshotComputer) *Indexer

NewIndexer creates an Indexer with the given store and snapshot computer.

func (*Indexer) IndexFile 

func (idx *Indexer) IndexFile(ctx context.Context, opts types.ExtractOptions) (*types.ExtractResult, error)

IndexFile extracts nodes and edges from a single file and stores them.

func (*Indexer) IndexRepo 

func (idx *Indexer) IndexRepo(ctx context.Context, repoURL, repoPath, commitHash string) (*types.Snapshot, error)

IndexRepo indexes all source files in a repository, skipping files whose content hash has not changed since the last index.

func (*Indexer) LastChangedFiles 

func (idx *Indexer) LastChangedFiles() []string

LastChangedFiles returns the file paths that changed in the most recent IndexRepo call.

func (*Indexer) Register 

func (idx *Indexer) Register(ext types.Extractor)

Register adds an extractor to the indexer's registry.

func (*Indexer) ResolveEdges 

func (idx *Indexer) ResolveEdges(ctx context.Context) (*resolver.ResolveStats, error)

ResolveEdges runs the cross-repo edge resolver to retarget dangling edges whose target hashes were computed with the wrong repo URL.

type SnapshotComputer 

type SnapshotComputer interface {
	ComputeSnapshot(ctx context.Context, repoHash types.Hash, commitHash string) (*types.Snapshot, error)
}

SnapshotComputer computes a point-in-time snapshot for a repository. Defined locally to avoid importing internal/snapshot.
