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

FileParser orchestrates AST parsing by triggering registered callbacks. Each file is processed only once.

Safe for concurrent use.

func NewFileParser(opts ...Option) *FileParser

func (p *FileParser) OnFileParsed(cb ParseCallback)

func (p *FileParser) ProcessFilename(fset *token.FileSet, filename string) []analysis.Diagnostic

ProcessFilename parses a file from disk and triggers all callbacks. Returns nil if already processed or if the file belongs to the Go distribution.

func (p *FileParser) ProcessFiles(fset *token.FileSet, files ...*ast.File) []analysis.Diagnostic

ProcessFiles triggers all callbacks for each provided AST file. Already-parsed files are skipped.

func (p *FileParser) Stats() (hits, misses, size uint64)

type Option func(*FileParser)

func WithParseFlags(flags parser.Mode) Option

WithParseFlags sets parser flags for file parsing. Default: parser.ParseComments | parser.SkipObjectResolution.

type ParseCallback func(fset *token.FileSet, file *ast.File) []analysis.Diagnostic
