+# css [![Build Status](https://travis-ci.org/reworkcss/css.svg?branch=master)](https://travis-ci.org/reworkcss/css)
+
+CSS parser / stringifier.
+
+## Installation
+
+    $ npm install css
+
+## Usage
+
+```js
+var css = require('css');
+var obj = css.parse('body { font-size: 12px; }', options);
+css.stringify(obj, options);
+```
+
+## API
+
+### css.parse(code, [options])
+
+Accepts a CSS string and returns an AST `object`.
+
+`options`:
+
+- silent: silently fail on parse errors.
+- source: the path to the file containing `css`. Makes errors and source
+  maps more helpful, by letting them know where code comes from.
+
+### css.stringify(object, [options])
+
+Accepts an AST `object` (as `css.parse` produces) and returns a CSS string.
+
+`options`:
+
+- indent: the string used to indent the output. Defaults to two spaces.
+- compress: omit comments and extraneous whitespace.
+- sourcemap: return a sourcemap along with the CSS output. Using the `source`
+  option of `css.parse` is strongly recommended when creating a source map.
+  Specify `sourcemap: 'generator'` to return the SourceMapGenerator object
+  instead of serializing the source map.
+- inputSourcemaps: (enabled by default, specify `false` to disable) reads any
+  source maps referenced by the input files when generating the output source
+  map. When enabled, file system access may be required for reading the
+  referenced source maps.
+
+### Example
+
+```js
+var ast = css.parse('body { font-size: 12px; }', { source: 'source.css' });
+
+var css = css.stringify(ast);
+
+var result = css.stringify(ast, { sourcemap: true });
+result.code // string with CSS
+result.map // source map object
+```
+
+### Errors
+
+Errors thrown during parsing have the following properties:
+
+- message: `String`. The full error message with the source position.
+- reason: `String`. The error message without position.
+- filename: `String` or `undefined`. The value of `options.source` if
+  passed to `css.parse`. Otherwise `undefined`.
+- line: `Integer`.
+- column: `Integer`.
+- source: `String`. The portion of code that couldn't be parsed.
+
+When parsing with the `silent` option, errors are listed in the
+`parsingErrors` property of the [`stylesheet`](#stylesheet) node instead
+of being thrown.
+
+If you create any errors in plugins such as in
+[rework](https://github.com/reworkcss/rework), you __must__ set the same
+properties for consistency.
+
+## AST
+
+Interactively explore the AST with <http://iamdustan.com/reworkcss_ast_explorer/>.
+
+### Common properties
+
+All nodes have the following properties.
+
+#### position
+
+Information about the position in the source string that corresponds to
+the node.
+
+`Object`:
+
+- start: `Object`:
+  - line: `Number`.
+  - column: `Number`.
+- end: `Object`:
+  - line: `Number`.
+  - column: `Number`.
+- source: `String` or `undefined`. The value of `options.source` if passed to
+  `css.parse`. Otherwise `undefined`.
+- content: `String`. The full source string passed to `css.parse`.
+
+The line and column numbers are 1-based: The first line is 1 and the first
+column of a line is 1 (not 0).
+
+The `position` property lets you know from which source file the node comes
+from (if available), what that file contains, and what part of that file was
+parsed into the node.
+
+#### type
+
+`String`. The possible values are the ones listed in the Types section below.
+
+#### parent
+
+A reference to the parent node, or `null` if the node has no parent.
+
+### Types
+
+The available values of `node.type` are listed below, as well as the available
+properties of each node (other than the common properties listed above.)
+
+#### stylesheet
+
+The root node returned by `css.parse`.
+
+- stylesheet: `Object`:
+  - rules: `Array` of nodes with the types `rule`, `comment` and any of the
+    at-rule types.
+  - parsingErrors: `Array` of `Error`s. Errors collected during parsing when
+    option `silent` is true.
+
+#### rule
+
+- selectors: `Array` of `String`s. The list of selectors of the rule, split
+  on commas. Each selector is trimmed from whitespace and comments.
+- declarations: `Array` of nodes with the types `declaration` and `comment`.
+
+#### declaration
+
+- property: `String`. The property name, trimmed from whitespace and
+  comments. May not be empty.
+- value: `String`. The value of the property, trimmed from whitespace and
+  comments. Empty values are allowed.
+
+#### comment
+
+A rule-level or declaration-level comment. Comments inside selectors,
+properties and values etc. are lost.
+
+- comment: `String`. The part between the starting `/*` and the ending `*/`
+  of the comment, including whitespace.
+
+#### charset
+
+The `@charset` at-rule.
+
+- charset: `String`. The part following `@charset `.
+
+#### custom-media
+
+The `@custom-media` at-rule.
+
+- name: `String`. The `--`-prefixed name.
+- media: `String`. The part following the name.

+- vendor: `String` or `undefined`. The vendor prefix in `@keyframes`, or
+  `undefined` if there is none.
+- keyframes: `Array` of nodes with the types `keyframe` and `comment`.
+
+#### keyframe
+
+- values: `Array` of `String`s. The list of “selectors” of the keyframe rule,
+  split on commas. Each “selector” is trimmed from whitespace.
+- declarations: `Array` of nodes with the types `declaration` and `comment`.

+# Change Log
+
+## 0.1.43
+
+* Performance improvements for `SourceMapGenerator` and `SourceNode`. See issue
+  #148 for some discussion and issues #150, #151, and #152 for implementations.
+
+## 0.1.42
+
+* Fix an issue where `SourceNode`s from different versions of the source-map
+  library couldn't be used in conjunction with each other. See issue #142.
+
+## 0.1.41
+
+* Fix a bug with getting the source content of relative sources with a "./"
+  prefix. See issue #145 and [Bug 1090768](bugzil.la/1090768).
+
+* Add the `SourceMapConsumer.prototype.computeColumnSpans` method to compute the
+  column span of each mapping.
+
+* Add the `SourceMapConsumer.prototype.allGeneratedPositionsFor` method to find
+  all generated positions associated with a given original source and line.
+
+## 0.1.40
+
+* Performance improvements for parsing source maps in SourceMapConsumer.
+
+## 0.1.39
+
+* Fix a bug where setting a source's contents to null before any source content
+  had been set before threw a TypeError. See issue #131.
+
+## 0.1.38
+
+* Fix a bug where finding relative paths from an empty path were creating
+  absolute paths. See issue #129.
+
+## 0.1.37
+
+* Fix a bug where if the source root was an empty string, relative source paths
+  would turn into absolute source paths. Issue #124.
+
+## 0.1.36
+
+* Allow the `names` mapping property to be an empty string. Issue #121.
+
+## 0.1.35
+
+* A third optional parameter was added to `SourceNode.fromStringWithSourceMap`
+  to specify a path that relative sources in the second parameter should be
+  relative to. Issue #105.
+
+* If no file property is given to a `SourceMapGenerator`, then the resulting
+  source map will no longer have a `null` file property. The property will
+  simply not exist. Issue #104.
+
+* Fixed a bug where consecutive newlines were ignored in `SourceNode`s.
+  Issue #116.
+
+## 0.1.34
+
+* Make `SourceNode` work with windows style ("\r\n") newlines. Issue #103.
+
+* Fix bug involving source contents and the
+  `SourceMapGenerator.prototype.applySourceMap`. Issue #100.
+
+## 0.1.33
+
+* Fix some edge cases surrounding path joining and URL resolution.
+
+* Add a third parameter for relative path to
+  `SourceMapGenerator.prototype.applySourceMap`.
+
+* Fix issues with mappings and EOLs.
+
+## 0.1.32

+  (issue 92).
+
+* Fixed test runner to actually report number of failed tests as its process
+  exit code.
+
+* Fixed a typo when reporting bad mappings (issue 87).
+
+## 0.1.31

+# 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.computeColumnSpans()
+
+Compute the last column for each generated mapping. The last column is
+inclusive.
+
+#### 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.allGeneratedPositionsFor(originalPosition)
+
+Returns all generated line and column information for the original source
+and line 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.
+
+and an array of objects is returned, each 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.
+
+* `skipValidation`: Optional. When `true`, disables validation of mappings as
+  they are added. This can improve performance but should be used with
+  discretion, as a last resort. Even then, one should avoid using this flag when
+  running tests, if possible.
+
+#### 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[, relativePath])
+
+Creates a SourceNode from generated code and a SourceMapConsumer.
+
+* `code`: The generated code
+
+* `sourceMapConsumer` The SourceMap for the generated code
+
+* `relativePath` The optional path that relative sources in `sourceMapConsumer`
+  should be relative to.
+
+#### 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
+
+[![Build Status](https://travis-ci.org/mozilla/source-map.png?branch=master)](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`.)
