source-list-map

# API

## Example

var SourceListMap = require("source-list-map").SourceListMap;
// Create a new map
var map = new SourceListMap();
// Add generated code that is map line to line to some soure
map.add("Generated\ncode1\n", "source-code.js", "Orginal\nsource");
// Add generated code that isn't mapped
map.add("Generated\ncode2\n");
// Get SourceMap and generated source
map.toStringWithSourceMap({ file: "generated-code.js" });
// {
// source: 'Generated\ncode1\nGenerated\ncode2\n',
// map: {
// version: 3,
// file: 'generated-code.js',
// sources: [ 'source-code.js' ],
// sourcesContent: [ 'Orginal\nsource' ],
// mappings: 'AAAA;AACA;;;'
// }
// }
// Convert existing SourceMap into SourceListMap
// (Only the first mapping per line is preserved)
var fromStringWithSourceMap = require("source-list-map").fromStringWithSourceMap;
var map = fromStringWithSourceMap("Generated\ncode", { version: 3, ... });

## <tt>new SourceListMap()</tt>

## <tt>SourceListMap.prototype.add</tt>

SourceListMap.prototype.add(generatedCode: string)
SourceListMap.prototype.add(generatedCode: string, source: string, originalSource: string)
SourceListMap.prototype.add(sourceListMap: SourceListMap)

Append some stuff.

## <tt>SourceListMap.prototype.prepend</tt>

SourceListMap.prototype.prepend(generatedCode: string)
SourceListMap.prototype.prepend(generatedCode: string, source: string, originalSource: string)
SourceListMap.prototype.prepend(sourceListMap: SourceListMap)

Prepend some stuff.

## <tt>SourceListMap.prototype.toString()</tt>

Get generated code.

## <tt>SourceListMap.prototype.toStringWithSourceMap</tt>

SourceListMap.prototype.toStringWithSourceMap(options: object)

Get generated code and SourceMap. `options` can contains `file` property which defines the `file` property of the SourceMap.

## <tt>SourceListMap.prototype.mapGeneratedCode</tt>

SourceListMap.prototype.mapGeneratedCode(fn: function) : SourceListMap

Applies `fn` to each generated code block (per line). The returned value is set as new generated code. Returns a new SourceListMap.

Removing and adding lines is supported. The SourceMap complexity will increase when doing this.
