Procs

func encode(values: seq[int]): string {....raises: [], tags: [], forbids: [].}

Encodes a series of integers into a VLQ base64 encoded string Source Edit

proc genSourceMap(source: string; outFile: string): SourceMap {.
    ...raises: [ValueError], tags: [], forbids: [].}

Source Edit

func parse(source: string): SourceInfo {....raises: [ValueError], tags: [],
    forbids: [].}

Parses the JS output for embedded line info So it can convert those into a series of mappings Source Edit

func toSourceMap(info: SourceInfo; file: string): SourceMap {....raises: [],
    tags: [], forbids: [].}

Convert from high level SourceInfo into the required SourceMap object Source Edit

Iterators

iterator tokenize(line: string): (int, string) {....raises: [], tags: [],
    forbids: [].}

Goes through a line and splits it into Nim identifiers and normal JS code. This allows us to map mangled names back to Nim names. Yields (column, name). Doesn't yield anything but identifiers. See mangleName in compiler/jsgen.nim for how name mangling is done Source Edit
