SourceMapper

Simple Swift implementation of the SourceMap specification: create, load, query, modify, and save source maps.

Examples

let map = try SourceMap(Data(contentsOf: mapURL))
print(map.file)

let unpackedMap = try UnpackedSourceMap(map)
let segment = unpackedMap.map(line: 12, column: 0)

var map = SourceMap()
map.sources = [.remote("a.scss")]
map.sourceRoot = "./../src/"
try map.set(segments: ..., validate: true)
let mapData = map.encode()
