sourcemap's Introduction

Source maps

Cross platform source map parser for Haxe programming language.

Usage

import sourcemap.SourcePos;

class Main {

	static public function main() {
		var data = "Contents of some .js.map file";
		var map = new SourceMap(data);

		var pos : SourcePos = map.originalPositionFor(1, 3);
		trace(pos);
		/*
			Outputs:
			{
				generatedLine:1,
				generatedColumn:3,
				originalColumn:10,
				originalLine:3,
				source:"/path/to/Test.hx",
				name:"methodName"
			}
		*/

		map.eachMapping(function (pos:SourcePos) {
			trace(pos);
		});
	}
}

sourcemap's Issues

Inclusion into HaxeFoundation/format

We have a need for sourcemap on heaps, and realized it would make sense and would be more convenient if it were directly in format (https://github.com/HaxeFoundation/format)

Would it be ok if I added sourcemap to format, adapting it to the reader/writer pattern like the rest of format?

Position error

Hej Aleksandr,

I don't know if the lib is up to date but, when I use it to parse .js.map file, there is sometimes an offset with the real position throw in the chrome debug console.
I don't know if it's linked to this issue, maybe do you remember : HaxeFoundation/haxe#10585
This is what sourcemap gives me :

Error: test

And this is the Chrome dev console output :
