+# Source Map
+
+This is a library to generate and consume the source map format
+[described here][format].
+
+This library is written in the Asynchronous Module Definition format, and works
+in the following environments:
+
+* Modern Browsers supporting ECMAScript 5 (either after the build, or with an
+ AMD loader such as RequireJS)
+
+* Inside Firefox (as a JSM file, after the build)
+
+* With NodeJS versions 0.8.X and higher
+
+## Node
+
+ $ npm install source-map
+
+## Building from Source (for everywhere else)
+
+Install Node and then run
+
+ $ git clone https://fitzgen@github.com/mozilla/source-map.git
+ $ cd source-map
+ $ npm link .
+
+Next, run
+
+ $ node Makefile.dryice.js
+
+This should spew a bunch of stuff to stdout, and create the following files:
+
+* `dist/source-map.js` - The unminified browser version.
+
+* `dist/source-map.min.js` - The minified browser version.
+
+* `dist/SourceMap.jsm` - The JavaScript Module for inclusion in Firefox source.
+
+## Examples
+
+### Consuming a source map
+
+ var rawSourceMap = {
+ version: 3,
+ file: 'min.js',
+ names: ['bar', 'baz', 'n'],
+ sources: ['one.js', 'two.js'],
+ sourceRoot: 'http://example.com/www/js/',
+ mappings: 'CAAC,IAAI,IAAM,SAAUA,GAClB,OAAOC,IAAID;CCDb,IAAI,IAAM,SAAUE,GAClB,OAAOA'
+ };
+
+ var smc = new SourceMapConsumer(rawSourceMap);
+
+ console.log(smc.sources);
+ // [ 'http://example.com/www/js/one.js',
+ // 'http://example.com/www/js/two.js' ]
+
+ console.log(smc.originalPositionFor({
+ line: 2,
+ column: 28
+ }));
+ // { source: 'http://example.com/www/js/two.js',
+ // line: 2,
+ // column: 10,
+ // name: 'n' }
+
+ console.log(smc.generatedPositionFor({
+ source: 'http://example.com/www/js/two.js',
+ line: 2,
+ column: 10
+ }));
+ // { line: 2, column: 28 }
+
+ smc.eachMapping(function (m) {
+ // ...
+ });
+
+### Generating a source map
+
+In depth guide:
+[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
+
+#### With SourceNode (high level API)
+
+ function compile(ast) {
+ switch (ast.type) {
+ case 'BinaryExpression':
+ return new SourceNode(
+ ast.location.line,
+ ast.location.column,
+ ast.location.source,
+ [compile(ast.left), " + ", compile(ast.right)]
+ );
+ case 'Literal':
+ return new SourceNode(
+ ast.location.line,
+ ast.location.column,
+ ast.location.source,
+ String(ast.value)
+ );
+ // ...
+ default:
+ throw new Error("Bad AST");
+ }
+ }
+
+ var ast = parse("40 + 2", "add.js");
+ console.log(compile(ast).toStringWithSourceMap({
+ file: 'add.js'
+ }));
+ // { code: '40 + 2',
+ // map: [object SourceMapGenerator] }
+
+#### With SourceMapGenerator (low level API)
+
+ var map = new SourceMapGenerator({
+ file: "source-mapped.js"
+ });
+
+ map.addMapping({
+ generated: {
+ line: 10,
+ column: 35
+ },
+ source: "foo.js",
+ original: {
+ line: 33,
+ column: 2
+ },
+ name: "christopher"
+ });
+
+ console.log(map.toString());
+ // '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
+
+## API
+
+Get a reference to the module:
+
+ // NodeJS
+ var sourceMap = require('source-map');
+
+ // Browser builds
+ var sourceMap = window.sourceMap;
+
+ // Inside Firefox
+ let sourceMap = {};
+ Components.utils.import('resource:///modules/devtools/SourceMap.jsm', sourceMap);
+
+### SourceMapConsumer
+
+A SourceMapConsumer instance represents a parsed source map which we can query
+for information about the original file positions by giving it a file position
+in the generated source.
+
+#### new SourceMapConsumer(rawSourceMap)
+
+The only parameter is the raw source map (either as a string which can be
+`JSON.parse`'d, or an object). According to the spec, source maps have the
+following attributes:
+
+* `version`: Which version of the source map spec this map is following.
+
+* `sources`: An array of URLs to the original source files.
+
+* `names`: An array of identifiers which can be referrenced by individual
+ mappings.
+
+* `sourceRoot`: Optional. The URL root from which all sources are relative.
+
+* `sourcesContent`: Optional. An array of contents of the original source files.
+
+* `mappings`: A string of base64 VLQs which contain the actual mappings.
+
+* `file`: Optional. The generated filename this source map is associated with.
+
+#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
+
+Returns the original source, line, and column information for the generated
+source's line and column positions provided. The only argument is an object with
+the following properties:
+
+* `line`: The line number in the generated source.
+
+* `column`: The column number in the generated source.
+
+and an object is returned with the following properties:
+
+* `source`: The original source file, or null if this information is not
+ available.
+
+* `line`: The line number in the original source, or null if this information is
+ not available.
+
+* `column`: The column number in the original source, or null or null if this
+ information is not available.
+
+* `name`: The original identifier, or null if this information is not available.
+
+#### SourceMapConsumer.prototype.generatedPositionFor(originalPosition)
+
+Returns the generated line and column information for the original source,
+line, and column positions provided. The only argument is an object with
+the following properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.
+
+* `column`: The column number in the original source.
+
+and an object is returned with the following properties:
+
+* `line`: The line number in the generated source, or null.
+
+* `column`: The column number in the generated source, or null.
+
+#### SourceMapConsumer.prototype.sourceContentFor(source)
+
+Returns the original source content for the source provided. The only
+argument is the URL of the original source file.
+
+#### SourceMapConsumer.prototype.eachMapping(callback, context, order)
+
+Iterate over each mapping between an original source/line/column and a
+generated line/column in this source map.
+
+* `callback`: The function that is called with each mapping. Mappings have the
+ form `{ source, generatedLine, generatedColumn, originalLine, originalColumn,
+ name }`
+
+* `context`: Optional. If specified, this object will be the value of `this`
+ every time that `callback` is called.
+
+* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
+ `SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
+ the mappings sorted by the generated file's line/column order or the
+ original's source/line/column order, respectively. Defaults to
+ `SourceMapConsumer.GENERATED_ORDER`.
+
+### SourceMapGenerator
+
+An instance of the SourceMapGenerator represents a source map which is being
+built incrementally.
+
+#### new SourceMapGenerator([startOfSourceMap])
+
+You may pass an object with the following properties:
+
+* `file`: The filename of the generated source that this source map is
+ associated with.
+
+* `sourceRoot`: A root for all relative URLs in this source map.
+
+#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
+
+Creates a new SourceMapGenerator based on a SourceMapConsumer
+
+* `sourceMapConsumer` The SourceMap.
+
+#### SourceMapGenerator.prototype.addMapping(mapping)
+
+Add a single mapping from original source line and column to the generated
+source's line and column for this source map being created. The mapping object
+should have the following properties:
+
+* `generated`: An object with the generated line and column positions.
+
+* `original`: An object with the original line and column positions.
+
+* `source`: The original source file (relative to the sourceRoot).
+
+* `name`: An optional original token name for this mapping.
+
+#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for an original source file.
+
+* `sourceFile` the URL of the original source file.
+
+* `sourceContent` the content of the source file.
+
+#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
+
+Applies a SourceMap for a source file to the SourceMap.
+Each mapping to the supplied source file is rewritten using the
+supplied SourceMap. Note: The resolution for the resulting mappings
+is the minimium of this map and the supplied map.
+
+* `sourceMapConsumer`: The SourceMap to be applied.
+
+* `sourceFile`: Optional. The filename of the source file.
+ If omitted, sourceMapConsumer.file will be used, if it exists.
+ Otherwise an error will be thrown.
+
+* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
+ to be applied. If relative, it is relative to the SourceMap.
+
+ This parameter is needed when the two SourceMaps aren't in the same
+ directory, and the SourceMap to be applied contains relative source
+ paths. If so, those relative source paths need to be rewritten
+ relative to the SourceMap.
+
+ If omitted, it is assumed that both SourceMaps are in the same directory,
+ thus not needing any rewriting. (Supplying `'.'` has the same effect.)
+
+#### SourceMapGenerator.prototype.toString()
+
+Renders the source map being generated to a string.
+
+### SourceNode
+
+SourceNodes provide a way to abstract over interpolating and/or concatenating
+snippets of generated JavaScript source code, while maintaining the line and
+column information associated between those snippets and the original source
+code. This is useful as the final intermediate representation a compiler might
+use before outputting the generated JS and source map.
+
+#### new SourceNode([line, column, source[, chunk[, name]]])
+
+* `line`: The original line number associated with this source node, or null if
+ it isn't associated with an original line.
+
+* `column`: The original column number associated with this source node, or null
+ if it isn't associated with an original column.
+
+* `source`: The original source's filename; null if no filename is provided.
+
+* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
+ below.
+
+* `name`: Optional. The original identifier.
+
+#### SourceNode.fromStringWithSourceMap(code, sourceMapConsumer)
+
+Creates a SourceNode from generated code and a SourceMapConsumer.
+
+* `code`: The generated code
+
+* `sourceMapConsumer` The SourceMap for the generated code
+
+#### SourceNode.prototype.add(chunk)
+
+Add a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+ `SourceNode`, or an array where each member is one of those things.
+
+#### SourceNode.prototype.prepend(chunk)
+
+Prepend a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+ `SourceNode`, or an array where each member is one of those things.
+
+#### SourceNode.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for a source file. This will be added to the
+`SourceMap` in the `sourcesContent` field.
+
+* `sourceFile`: The filename of the source file
+
+* `sourceContent`: The content of the source file
+
+#### SourceNode.prototype.walk(fn)
+
+Walk over the tree of JS snippets in this node and its children. The walking
+function is called once for each snippet of JS and is passed that snippet and
+the its original associated source's line/column location.
+
+* `fn`: The traversal function.
+
+#### SourceNode.prototype.walkSourceContents(fn)
+
+Walk over the tree of SourceNodes. The walking function is called for each
+source file content and is passed the filename and source content.
+
+* `fn`: The traversal function.
+
+#### SourceNode.prototype.join(sep)
+
+Like `Array.prototype.join` except for SourceNodes. Inserts the separator
+between each of this source node's children.
+
+* `sep`: The separator.
+
+#### SourceNode.prototype.replaceRight(pattern, replacement)
+
+Call `String.prototype.replace` on the very right-most source snippet. Useful
+for trimming whitespace from the end of a source node, etc.
+
+* `pattern`: The pattern to replace.
+
+* `replacement`: The thing to replace the pattern with.
+
+#### SourceNode.prototype.toString()
+
+Return the string representation of this source node. Walks over the tree and
+concatenates all the various snippets together to one string.
+
+### SourceNode.prototype.toStringWithSourceMap([startOfSourceMap])
+
+Returns the string representation of this tree of source nodes, plus a
+SourceMapGenerator which contains all the mappings between the generated and
+original sources.
+
+The arguments are the same as those to `new SourceMapGenerator`.
+
+## Tests
+
+[](https://travis-ci.org/mozilla/source-map)
+
+Install NodeJS version 0.8.0 or greater, then run `node test/run-tests.js`.
+
+To add new tests, create a new file named `test/test-<your new test name>.js`
+and export your test functions with names that start with "test", for example
+
+ exports["test doing the foo bar"] = function (assert, util) {
+ ...
+ };
+
+The new test will be located automatically when you run the suite.
+
+The `util` argument is the test utility module located at `test/source-map/util`.
+
+The `assert` argument is a cut down version of node's assert module. You have
+access to the following assertion functions:
+
+* `doesNotThrow`
+
+* `equal`
+
+* `ok`
+
+* `strictEqual`
+
+* `throws`
+
+(The reason for the restricted set of test functions is because we need the
+tests to run inside Firefox's test suite as well and so the assert module is
+shimmed in that environment. See `build/assert-shim.js`.)
