What's New

2.0.0

2023-04-20T10:22:25Z

Restructure to work properly with Swift concurrency.

Split the SourceMap class into two Sendable structures SourceMap and the immutable UnpackedSourceMap.

The UnpackedSourceMap type is the new home for the map(...) method on a segment cache.

Move index validation and cross-checks to the point of assigning the segments rather than serialising the source map.

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()
