Overview ¶

Package sourcemap records backend-independent relationships between generated code and TypeRB source. Target-specific source-map encodings are deliberately layered on top of this model.

Functions ¶

func EndMarker ¶

func EndMarker(id int) string

func IsMarkerLine ¶

func IsMarkerLine(line string) bool

func PositionAt ¶

func PositionAt(source string, offset int) token.Position

func StartMarker ¶

func StartMarker(id int) string

func WithGoLineDirectives ¶ added in v0.2.9

func WithGoLineDirectives(output, generatedPath string, mapping Map) string

WithGoLineDirectives projects the shared map into Go's compiler-recognized line directives. Delve then sees TypeRB source paths without needing a TypeRB-specific breakpoint or stack-frame translation layer.

Types ¶

type Generated ¶

type Generated struct {
	Output string
	Map    Map
}

type Location ¶

type Location struct {
	Path string
	Span token.Span
}

type Map ¶

type Map struct {
	Version  int
	Mappings []Mapping
}

func ExtractMarkers ¶

func ExtractMarkers(marked string, locations map[int]Location) (string, Map)

ExtractMarkers removes codegen-only marker lines after target formatting and converts their byte ranges into the shared mapping model.

func (Map) SourceAt ¶

func (m Map) SourceAt(generated token.Position) (Location, bool)

type Mapping ¶

type Mapping struct {
	Generated token.Span
	Source    Location
}

type Recorder ¶

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

func NewRecorder ¶

func NewRecorder(path string) *Recorder

func (*Recorder) Build ¶

func (r *Recorder) Build(output string) Map

func (*Recorder) Record ¶

func (r *Recorder) Record(start, end int, source token.Span)
