func DetectLanguage ¶

func DetectLanguage(filePath string) model.Language

DetectLanguage returns the model.Language for the given file path, based solely on the file extension. Mirrors EXTENSION_MAP in src/extraction/grammars.ts. File-level-only languages (yaml, twig, properties) return their own Language constant so the indexer records a file row with zero nodes, matching the original's behaviour.

func DetectLanguageContent ¶

func DetectLanguageContent(path string, content []byte) model.Language

DetectLanguageContent returns the model.Language for path, using content to disambiguate ambiguous extensions. For unambiguous extensions it delegates to the path-only DetectLanguage. For `.h` (which DetectLanguage defaults to C for back-compat) it sniffs content: Objective-C markers (`@interface`/`@protocol`/ `@implementation`/`#import`) win first → LangObjC; else C++ markers → LangCPP; else LangC. Callers that have the file content available (the indexer extract path, the parity test) should prefer this over DetectLanguage.

func DetectSpecScore ¶

func DetectSpecScore(filePath string, content []byte) bool

DetectSpecScore reports whether the file at filePath is a SpecScore artifact: a `.md`/`README.md` file located under a `spec/` path segment whose leading YAML frontmatter (delimited by `---` … `---` at the very top) carries a `format:` key whose value is `https://specscore.md/<kind>-specification`. Only the leading frontmatter block is scanned, not the whole file.

func ExtractFile ¶

func ExtractFile(path string, content []byte, lang model.Language) (model.ExtractionResult, error)

ExtractFile parses content as lang, extracts a file node (and, eventually, all symbols), and returns the result. The AST-walking logic for individual symbol kinds will be added in subsequent tasks; this skeleton always succeeds and returns at least the file node.

func ExtractGoRoutes ¶

func ExtractGoRoutes(filePath string, content []byte, fileNodeID string) ([]model.Node, []model.UnresolvedReference)

ExtractGoRoutes extracts net/http HandleFunc/Handle route registrations from Go source, mirroring the goResolver.extract() in src/resolution/frameworks/go.ts.

This is called from ExtractFile after the main tree-sitter walk.

func IsFileLevelOnly ¶

func IsFileLevelOnly(lang model.Language) bool

IsFileLevelOnly reports whether lang is tracked at the file-record level only — stored in the files table with zero symbol nodes. Mirrors isFileLevelOnlyLanguage() in src/extraction/grammars.ts.

func IsGeneratedFile ¶

func IsGeneratedFile(filePath string) bool

IsGeneratedFile reports whether filePath looks like a tool-generated source file, based on its filename. Path-only — does not read content.
