+
+### Branching
+
+__2.X now supports node 0.10+ due to switching out a dependency.__
+
+### Usage
+
+#### Write inline source maps
+Inline source maps are embedded in the source file.
+
+Example:
+```javascript
+var gulp = require('gulp');
+var plugin1 = require('gulp-plugin1');
+var plugin2 = require('gulp-plugin2');
+var sourcemaps = require('gulp-sourcemaps');
+
+gulp.task('javascript', function() {
+  gulp.src('src/**/*.js')
+    .pipe(sourcemaps.init())
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write())
+    .pipe(gulp.dest('dist'));
+});
+```
+
+All plugins between `sourcemaps.init()` and `sourcemaps.write()` need to have support for `gulp-sourcemaps`. You can find a list of such plugins in the [wiki](https://github.com/gulp-sourcemaps/gulp-sourcemaps/wiki/Plugins-with-gulp-sourcemaps-support).
+
+
+#### Write external source map files
+
+To write external source map files, pass a path relative to the destination to `sourcemaps.write()`.
+
+Example:
+```javascript
+var gulp = require('gulp');
+var plugin1 = require('gulp-plugin1');
+var plugin2 = require('gulp-plugin2');
+var sourcemaps = require('gulp-sourcemaps');
+
+gulp.task('javascript', function() {
+  gulp.src('src/**/*.js')
+    .pipe(sourcemaps.init())
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write('../maps'))
+    .pipe(gulp.dest('dist'));
+});
+```
+
+#### Load existing source maps
+
+To load existing source maps, pass the option `loadMaps: true` to `sourcemaps.init()`.
+
+Example:
+```javascript
+var gulp = require('gulp');
+var plugin1 = require('gulp-plugin1');
+var plugin2 = require('gulp-plugin2');
+var sourcemaps = require('gulp-sourcemaps');
+
+gulp.task('javascript', function() {
+  gulp.src('src/**/*.js')
+    .pipe(sourcemaps.init({loadMaps: true}))
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write())
+    .pipe(gulp.dest('dist'));
+});
+```
+
+#### Handle large files
+
+To handle large files, pass the option `largeFile: true` to `sourcemaps.init()`.
+
+Example:
+```javascript
+var gulp = require('gulp');
+var plugin1 = require('gulp-plugin1');
+var plugin2 = require('gulp-plugin2');
+var sourcemaps = require('gulp-sourcemaps');
+
+gulp.task('javascript', function() {
+  gulp.src('src/**/*.js')
+    .pipe(sourcemaps.init({largeFile: true}))
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write())
+    .pipe(gulp.dest('dist'));
+});
+```
+
+#### Handle source files from different directories
+
+Use the `base` option on `gulp.src` to make sure all files are relative to a common base directory.
+
+Example:
+```javascript
+var gulp = require('gulp');
+var plugin1 = require('gulp-plugin1');
+var plugin2 = require('gulp-plugin2');
+var sourcemaps = require('gulp-sourcemaps');
+
+gulp.task('javascript', function() {
+gulp.src(['src/test.js', 'src/testdir/test2.js'], { base: 'src' })
+    .pipe(sourcemaps.init())
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write('../maps'))
+    .pipe(gulp.dest('dist'));
+});
+```
+
+#### Alter `sources` property on sourcemaps
+
+The exported `mapSources` method gives full control over the source paths. It takes a function that is called for every source and receives the default source path as a parameter and the original vinyl file.
+
+Example:
+```javascript
+gulp.task('javascript', function() {
+  var stream = gulp.src('src/**/*.js')
+    .pipe(sourcemaps.init())
+      .pipe(plugin1())
+      .pipe(plugin2())
+      // be careful with the sources returned otherwise contents might not be loaded properly
+      .pipe(sourcemaps.mapSources(function(sourcePath, file) {
+        // source paths are prefixed with '../src/'
+        return '../src/' + sourcePath;
+      }))
+    .pipe(sourcemaps.write('../maps')
+    .pipe(gulp.dest('public/scripts'));
+});
+```
+
+#### Generate Identity Sourcemap
+
+The exported `identityMap` method allows you to generate a full valid source map encoding no changes (slower, only for Javascript and CSS) instead of the default empty source map (no mappings, fast). __Use this option if you get missing or incorrect mappings, e.g. when debugging.__
+
+Example:
+```javascript
+gulp.task('javascript', function() {
+  var stream = gulp.src('src/**/*.js')
+    .pipe(sourcemaps.init())
+      // An identity sourcemap will be generated at this step
+      .pipe(sourcemaps.identityMap())
+      .pipe(plugin1())
+      .pipe(plugin2())
+    .pipe(sourcemaps.write('../maps')
+    .pipe(gulp.dest('public/scripts'));
+});
+```
+
+
+### Init Options
+
+- `loadMaps`
+
+  Set to true to load existing maps for source files. Supports the following:
+    - inline source maps
+    - source map files referenced by a `sourceMappingURL=` comment
+    - source map files with the same name (plus .map) in the same directory
+
+
+- `identityMap`
+
+  __This option is deprecated. Upgrade to use our [`sourcemap.identityMap`](#generate-identity-sourcemap) API.__
+
+
+### Write Options
+
+- `addComment`
+
+  By default a comment containing / referencing the source map is added. Set this to `false` to disable the comment (e.g. if you want to load the source maps by header).
+
+  Example:
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write('../maps', {addComment: false}))
+      .pipe(gulp.dest('dist'));
+  });
+  ```
+
+- `includeContent`
+
+  By default the source maps include the source code. Pass `false` to use the original files.
+
+  Including the content is the recommended way, because it "just works". When setting this to `false` you have to host the source files and set the correct `sourceRoot`.
+
+- `sourceRoot`
+
+  Set the location where the source files are hosted (use this when `includeContent` is set to `false`). This is usually a URL (or an absolute URL path), not a local file system path.
+  By default the source root is '' or in case `destPath` is set, the relative path from the source map to the source base directory (this should work for many dev environments).
+  If a relative path is used (empty string or one starting with a `.`), it is interpreted as a path relative to the destination. The plugin rewrites it to a path relative to each source map.
+
+  Example:
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write({includeContent: false, sourceRoot: '/src'}))
+      .pipe(gulp.dest('dist'));
+  });
+  ```
+
+  Example (using a function):
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write({
+        includeContent: false,
+        sourceRoot: function(file) {
+          return '/src';
+        }
+       }))
+      .pipe(gulp.dest('dist'));
+  });
+  ```
+
+  Example (relative path):
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write('.', {includeContent: false, sourceRoot: '../src'}))
+      .pipe(gulp.dest('dist'));
+  });
+  ```
+  In this case for a file written to `dist/subdir/example.js`, the source map is written to `dist/subdir/example.js.map` and the sourceRoot will be `../../src` (resulting in the full source path `../../src/subdir/example.js`).
+
+- `destPath`
+
+  Set the destination path (the same you pass to `gulp.dest()`). If the source map destination path is not a subpath of the destination path, this is needed to get the correct path in the `file` property of the source map.
+  In addition, it allows to automatically set a relative `sourceRoot` if none is set explicitly.
+
+- `sourceMappingURLPrefix`
+
+  Specify a prefix to be prepended onto the source map URL when writing external source maps. Relative paths will have their leading dots stripped.
+
+  Example:
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write('../maps', {
+        sourceMappingURLPrefix: 'https://asset-host.example.com/assets'
+      }))
+      .pipe(gulp.dest('public/scripts'));
+  });
+  ```
+
+  This will result in a source mapping URL comment like `sourceMappingURL=https://asset-host.example.com/assets/maps/helloworld.js.map`.
+
+- `sourceMappingURL`
+
+  If you need full control over the source map URL you can pass a function to this option. The output of the function must be the full URL to the source map (in function of the output file).
+
+  Example:
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write('../maps', {
+        sourceMappingURL: function(file) {
+          return 'https://asset-host.example.com/' + file.relative + '.map';
+        }
+      }))
+      .pipe(gulp.dest('public/scripts'));
+  });
+  ```
+
+  This will result in a source mapping URL comment like `sourceMappingURL=https://asset-host.example.com/helloworld.js.map`.
+
+- `mapFile`
+
+  This option allows to rename the map file. It takes a function that is called for every map and receives the default map path as a parameter.
+
+  Example:
+  ```javascript
+  gulp.task('javascript', function() {
+    var stream = gulp.src('src/**/*.js')
+      .pipe(sourcemaps.init())
+        .pipe(plugin1())
+        .pipe(plugin2())
+      .pipe(sourcemaps.write('../maps', {
+        mapFile: function(mapFilePath) {
+          // source map files are named *.map instead of *.js.map
+          return mapFilePath.replace('.js.map', '.map');
+        }
+      }))
+      .pipe(gulp.dest('public/scripts'));
+  });
+  ```
+
+- `mapSources`
+
+  __This option is deprecated. Upgrade to use our [`sourcemap.mapSources`](#alter-sources-property-on-sourcemaps) API.__
+
+- `charset`
+
+  Sets the charset for inline source maps. Default: `utf8`
+
+- `clone`
+
+  Clones the original file for creation of the map file. Could be important if file history is important. See [file.clone()](https://github.com/gulpjs/vinyl#filecloneoptions) for possible options. Default: `{deep:false, contents:false}`
+
+### Plugin developers only:
+
+- **How to add source map support to plugins**
+
+  - Generate a source map for the transformation the plugin is applying
+  - **Important**: Make sure the paths in the generated source map (`file` and `sources`) are relative to `file.base` (e.g. use `file.relative`).
+  - Apply this source map to the vinyl `file`. E.g. by using [vinyl-sourcemaps-apply](https://github.com/gulp-sourcemaps/vinyl-sourcemaps-apply).
+    This combines the source map of this plugin with the source maps coming from plugins further up the chain.
+  - Add your plugin to the [wiki page](https://github.com/gulp-sourcemaps/gulp-sourcemaps/wiki/Plugins-with-gulp-sourcemaps-support)
+
+  #### Example:
+
+  ```js
+  var through = require('through2');
+  var applySourceMap = require('vinyl-sourcemaps-apply');
+  var myTransform = require('myTransform');
+
+  module.exports = function(options) {
+
+    function transform(file, encoding, callback) {
+      // generate source maps if plugin source-map present
+      if (file.sourceMap) {
+        options.makeSourceMaps = true;
+      }
+
+      // do normal plugin logic
+      var result = myTransform(file.contents, options);
+      file.contents = new Buffer(result.code);
+
+      // apply source map to the chain
+      if (file.sourceMap) {
+        applySourceMap(file, result.map);
+      }
+
+      this.push(file);
+      callback();
+    }
+
+    return through.obj(transform);
+  };
+  ```
+
+  - **Very sourcemaps is working**
+
+    See example below or refer to [test/write.js](./test/write.js)
+
+  #### Example:
+  ```js
+  var stream = plugin();
+  var init = sourcemaps.init();
+  var write = sourcemaps.write();
+
+  init.pipe(stream).pipe(write);
+
+  write.on('data', function (file) {
+    assert(...);
+    cb();
+  });
+
+  init.write(new gutil.File(...));
+  init.end();
+  ```
+
+### Debugging
+
+All debugging output relys on [visionmedia/debug](https://github.com/visionmedia/debug). Fllow the directions to set the
+environment variable ``$DEBUG`.
+
+For a few examples of debug you could use:
+
+```sh
+  DEBUG='gulp-sourcemaps:*' #everything
+  DEBUG='gulp-sourcemaps:init' #init/index.js
+  DEBUG='gulp-sourcemaps:init:*' #init/index.internals.js
+  DEBUG='gulp-sourcemaps:write:' #write/index.js
+  DEBUG='gulp-sourcemaps:write:*' #write/index.internals.js
+  DEBUG='gulp-sourcemaps:write:,gulp-sourcemaps:init:**' #write/index.internals.js and init/index.internals.js

+## Information

+
+## What is this?
+Read this for more info about how this plays into the grand scheme of things [https://medium.com/@eschoff/3828e8126466](https://medium.com/@eschoff/3828e8126466)
+
+## File
+
+```javascript
+var File = require('vinyl');
+
+var coffeeFile = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee",
+  contents: new Buffer("test = 123")
+});
+```
+
+### isVinyl
+When checking if an object is a vinyl file, you should not use instanceof. Use the isVinyl function instead.
+
+```js
+var File = require('vinyl');
+
+var dummy = new File({stuff});
+var notAFile = {};
+
+File.isVinyl(dummy); // true
+File.isVinyl(notAFile); // false
+```
+
+### isCustomProp
+Vinyl checks if a property is not managed internally, such as `sourceMap`. This is than used in `constructor(options)` when setting, and `clone()` when copying properties.
+
+```js
+var File = require('vinyl');
+
+File.isCustomProp('sourceMap'); // true
+File.isCustomProp('path'); // false -> internal getter/setter
+```
+
+Read more in [Extending Vinyl](#extending-vinyl).
+
+### constructor(options)
+#### options.cwd
+Type: `String`<br><br>Default: `process.cwd()`
+
+#### options.base
+Used for relative pathing. Typically where a glob starts.
+
+Type: `String`<br><br>Default: `options.cwd`
+
+#### options.path
+Full path to the file.
+
+Type: `String`<br><br>Default: `undefined`
+
+#### options.history
+Path history. Has no effect if `options.path` is passed.
+
+Type: `Array`<br><br>Default: `options.path ? [options.path] : []`
+
+#### options.stat
+The result of an fs.stat call. See [fs.Stats](http://nodejs.org/api/fs.html#fs_class_fs_stats) for more information.
+
+Type: `fs.Stats`<br><br>Default: `null`
+
+#### options.contents
+File contents.
+
+Type: `Buffer, Stream, or null`<br><br>Default: `null`
+
+#### options.{custom}
+Any other option properties will just be assigned to the new File object.
+
+```js
+var File = require('vinyl');
+
+var file = new File({foo: 'bar'});
+file.foo === 'bar'; // true
+```
+
+### isBuffer()
+Returns true if file.contents is a Buffer.
+
+### isStream()
+Returns true if file.contents is a Stream.
+
+### isNull()
+Returns true if file.contents is null.
+
+### clone([opt])
+Returns a new File object with all attributes cloned.<br>By default custom attributes are deep-cloned.
+
+If opt or opt.deep is false, custom attributes will not be deep-cloned.
+
+If opt.contents is false, it will copy file.contents Buffer's reference.
+
+### pipe(stream[, opt])
+If file.contents is a Buffer, it will write it to the stream.
+
+If file.contents is a Stream, it will pipe it to the stream.
+
+If file.contents is null, it will do nothing.
+
+If opt.end is false, the destination stream will not be ended (same as node core).
+
+Returns the stream.
+
+### inspect()
+Returns a pretty String interpretation of the File. Useful for console.log.
+
+### contents
+The [Stream](https://nodejs.org/api/stream.html#stream_stream) or [Buffer](https://nodejs.org/api/buffer.html#buffer_class_buffer) of the file as it was passed in via options, or as the result of modification.
+
+For example:
+
+```js
+if (file.isBuffer()) {
+    console.log(file.contents.toString()); // logs out the string of contents
+}
+```
+
+### path
+Absolute pathname string or `undefined`. Setting to a different value pushes the old value to `history`.
+
+### history
+Array of `path` values the file object has had, from `history[0]` (original) through `history[history.length - 1]` (current). `history` and its elements should normally be treated as read-only and only altered indirectly by setting `path`.
+
+### relative
+Returns path.relative for the file base and file path.
+
+Example:
+
+```javascript
+var file = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee"
+});
+
+console.log(file.relative); // file.coffee
+```
+
+### dirname
+Gets and sets path.dirname for the file path.
+
+Example:
+
+```javascript
+var file = new File({
+  cwd: "/",
+  base: "/test/",
+  path: "/test/file.coffee"
+});
+
+console.log(file.dirname); // /test
+
+file.dirname = '/specs';

+```
+
+### extname
+Gets and sets path.extname for the file path.
+
+Example:

+
+## Extending Vinyl
+When extending Vinyl into your own class with extra features, you need to think about a few things.
+
+When you have your own properties that are managed internally, you need to extend the static `isCustomProp` method to return `false` when one of these properties is queried.
+
+```js
+const File = require('vinyl');
+
+const builtInProps = ['foo', '_foo'];
+
+class SuperFile extends File {
+  constructor(options) {
+    super(options);
+    this._foo = 'example internal read-only value';
+  }
+
+  get foo() {
+    return this._foo;
+  }
+
+  static isCustomProp(name) {
+    return super.isCustomProp(name) && builtInProps.indexOf(name) === -1;
+  }
+}
+```
+
+This makes properties `foo` and `_foo` ignored when cloning, and when passed in options to `constructor(options)` so they don't get assigned to the new object.
+
+Same goes for `clone()`. If you have your own internal stuff that needs special handling during cloning, you should extend it to do so.
