Functions ¶

func SourceReader ¶

func SourceReader(runtime *lisp.Runtime, lerr *lisp.LVal) func(string) ([]byte, error)

SourceReader returns a diagnostic source callback using the active runtime. Inline labels prefer retained text; all file reads go through the library. A missing or refusing library never falls back to the host filesystem.

Types ¶

type Reader ¶

type Reader struct {
	lisp.Reader
	// contains filtered or unexported fields
}

Reader retains up to 4 MiB of inline sources by display label, evicting oldest entries first. Physical sources continue through the underlying reader and are retrieved through the active library. Like the runtime reader it wraps, it is used by one evaluation at a time.

func NewReader ¶

func NewReader(reader lisp.Reader) *Reader

NewReader wraps the runtime's parser to retain load-string/load-bytes text.

func (*Reader) Read ¶

func (r *Reader) Read(name string, input io.Reader) ([]*lisp.LVal, error)

Read records the bytes actually parsed, never treating name as a file path.

func (*Reader) ReadLocation ¶

func (r *Reader) ReadLocation(name, loc string, input io.Reader) ([]*lisp.LVal, error)

ReadLocation preserves physical source locations without caching file contents.
