+
+## 5.0.0
+
+_2020-04-27_
+
+### Features
+
+- Added `getBabelOutputPlugin` and `createBabelOutputPluginFactory` exports which can be used to transform generated code
+- Added `skipPreflightCheck` option. The plugin performs some extra checks to see if the passed configuration is correct and matching its expectations. This comes with some runtime overhead and can slow down builds. If you know what you are doing and you are confident that you have configured things correctly you can disable those checks with this option.
+- Published as `@rollup/plugin-babel`
+
+### Updates
+
+- Default export exported as `getBabelInputPlugin` for symmetry with `getBabelOutputPlugin`
+
+### Breaking Changes
+
+- Minimum compatible Rollup version is 1.2.0
+- Minimum supported Node version is 10.0.0
+- `.custom` factory is now available as separate `createBabelInputPluginFactory` export
+- Removed `externalHelpers` & `runtimeHelpers` options. There is now a single `babelHelpers` option which can take one of `'bundled'`, `'inline'`, `'runtime'` and `'external'` as a value. The default is `'bundled'` which matches 4.x behavior, but it is recommended to configure this option explicitly.
+
+## 4.3.2
+
+- Fixed usage with `externalHelpers: true` option
+
+## 4.3.1
+
+- Add `.js` extension to the virtual babel helpers file (only matters when using `preserveModules` option in rollup)
+
+## 4.3.0
+
+- Added `.custom` builder.
+- Fail build when a plugin tries to add non existent babel helper
+
+## 4.2.0
+
+Allow `rollup@1` as peer dependency.
+
+## 4.1.0
+
+- Fixed "preflight check" for ignored files.
+- Return `null` when no transformation has been done (fixing source maps for this case)
+
+## 4.0.3
+
+Fixed fallback class transform in "preflight check".
+
+## 4.0.2
+
+Fixed `rollup` peer dependency.
+
+## 4.0.0
+
+Babel 7 compatible! (dropped Babel 6 compatibility though).
+
+Additionally:
+
+- Internal preflight checks are created now per plugin instance, so using 2 instances of rollup-plugin-babel (i.e. targeting 2 different set of files with include/exclude options) shouldn't conflict with each other
+- Transpiling by default only what Babel transpiles - files with those extensions: .js, .jsx, .es6, .es, .mjs. You can customize this with new `extensions` option. This also fixes long standing issue with rollup-plugin-babel trying to transform JSON files.
+
+## 3.0.3
+
+- Drop babel7 support. Use 4.0.0-beta if you use babel 7
+- Use "module" in addition to "jsnext:main" ([#150](https://github.com/rollup/rollup-plugin-babel/issues/150))
+- Remove unused babel helpers namespace declaration & expression ([#164](https://github.com/rollup/rollup-plugin-babel/issues/164))
+
+## 3.0.2
+
+- Fix regression with Babel 6 ([#158](https://github.com/rollup/rollup-plugin-babel/issues/158))
+
+## 3.0.1
+
+- Wasn't working, fix bug with transform (not using es2015-classes for preflight check)
+
+## 3.0.0
+
+- Drop Node 0.10/0.12 (Use native `Object.assign`)
+- Change `babel-core` to be a peerDependency
+- Support `babel-core` v7 as well as a peerDep (no changes necessary)
+
+## 2.7.1
+
+- Prevent erroneous warnings about duplicated runtime helpers ([#105](https://github.com/rollup/rollup-plugin-babel/issues/105))
+- Ignore `ignore` option in preflight check ([#102](https://github.com/rollup/rollup-plugin-babel/issues/102))
+- Allow custom `moduleName` with `runtime-helpers` ([#95](https://github.com/rollup/rollup-plugin-babel/issues/95))
+
+## 2.7.0
+
+- Add `externalHelpersWhitelist` option ([#92](https://github.com/rollup/rollup-plugin-babel/pull/92))
+- Ignore `only` option during preflight checks ([#98](https://github.com/rollup/rollup-plugin-babel/issues/98))
+- Use `options.onwarn` if available ([#84](https://github.com/rollup/rollup-plugin-babel/issues/84))
+- Update documentation and dependencies
+
+## 2.6.1
+
+- Return a `name`
+
+## 2.6.0
+
+- Use `\0` convention for helper module ID ([#64](https://github.com/rollup/rollup-plugin-babel/issues/64))
+
+## 2.5.1
+
+- Don't mutate `options.plugins` ([#47](https://github.com/rollup/rollup-plugin-babel/issues/47))
+
+## 2.5.0
+
+- Import `babelHelpers` rather than injecting them – allows `transform` function to be pure ([#rollup/658](https://github.com/rollup/rollup/pull/658#issuecomment-223876824))
+
+## 2.4.0
+
+- Add `externalHelpers` option ([#41](https://github.com/rollup/rollup-plugin-babel/pull/41))
+
+## 2.3.9
+
+- Do not rename Babel helpers ([#34](https://github.com/rollup/rollup-plugin-babel/pull/34))
+
+## 2.3.8
+
+- Create new version to (hopefully) solve bizarre CI issue
+
+## 2.3.7
+
+- Be less clever about renaming Babel helpers ([#19](https://github.com/rollup/rollup-plugin-babel/issues/19))
+
+## 2.3.6
+
+- Fix cache misses in preflight check ([#29](https://github.com/rollup/rollup-plugin-babel/pull/29))
+
+## 2.3.5
+
+- Use class transformer local to plugin, not project being built
+
+## 2.3.4
+
+- Ensure class transformer is present for preflight check, and only run check once per directory ([#23](https://github.com/rollup/rollup-plugin-babel/issues/23))
+
+## 2.3.3
+
+- Fix helper renaming ([#22](https://github.com/rollup/rollup-plugin-babel/issues/22))
+
+## 2.3.1-2
+

+
+- Allow `transform-runtime` Babel plugin, if combined with `runtimeHelpers: true` option ([#17](https://github.com/rollup/rollup-plugin-babel/issues/17))
+- More permissive handling of helpers – only warn if inline helpers are duplicated
+- Handle plugins that change export patterns ([#18](https://github.com/rollup/rollup-plugin-babel/issues/18))
+
+## 2.2.0
+
+- Preflight checks are run per-file, to avoid configuration snafus ([#16](https://github.com/rollup/rollup-plugin-babel/issues/16))
+
+## 2.1.0
+
+- Generate sourcemaps by default
+
+## 2.0.1

+
+# @rollup/plugin-babel
+
+🍣 A Rollup plugin for seamless integration between Rollup and Babel.
+
+## Why?
+
+If you're using Babel to transpile your ES6/7 code and Rollup to generate a standalone bundle, you have a couple of options:
+
+- run the code through Babel first, being careful to exclude the module transformer, or
+- run the code through Rollup first, and _then_ pass it to Babel.
+
+Both approaches have disadvantages – in the first case, on top of the additional configuration complexity, you may end up with Babel's helpers (like `classCallCheck`) repeated throughout your code (once for each module where the helpers are used). In the second case, transpiling is likely to be slower, because transpiling a large bundle is much more work for Babel than transpiling a set of small files.
+
+Either way, you have to worry about a place to put the intermediate files, and getting sourcemaps to behave becomes a royal pain.
+
+Using Rollup with `@rollup/plugin-babel` makes the process far easier.
+
+## Requirements
+
+This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v10.0.0+) and Rollup v1.20.0+.
+
+## Install
+
+```bash
+npm install @rollup/plugin-babel --save-dev
+```
+
+## Usage
+
+Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
+
+```js
+import { babel } from '@rollup/plugin-babel';
+
+const config = {
+  input: 'src/index.js',
+  output: {
+    dir: 'output',
+    format: 'esm'
+  },
+  plugins: [babel({ babelHelpers: 'bundled' })]
+};
+
+export default config;
+```
+
+Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
+
+### Using With `@rollup/plugin-commonjs`
+
+When using `@rollup/plugin-babel` with `@rollup/plugin-commonjs` in the same Rollup configuration, it's important to note that `@rollup/plugin-commonjs` _must_ be placed before this plugin in the `plugins` array for the two to work together properly. e.g.
+
+```js
+import { babel } from '@rollup/plugin-babel';
+import commonjs from '@rollup/plugin-commonjs';
+
+const config = {
+  ...
+  plugins: [
+    commonjs(),
+    babel({ babelHelpers: 'bundled' })
+  ],
+};
+```
+
+## Options
+
+This plugin respects Babel [configuration files](https://babeljs.io/docs/en/configuration) by default and they are generally the best place to put your configuration.
+
+You can also run Babel on the generated chunks instead of the input files. Even though this is slower, it is the only way to transpile Rollup's auto-generated wrapper code to lower compatibility targets than ES5, see [Running Babel on the generated code](#running-babel-on-the-generated-code) for details.
+
+All options are as per the [Babel documentation](https://babeljs.io/docs/en/options), plus the following:
+
+### `exclude`
+
+Type: `String | RegExp | Array[...String|RegExp]`<br>
+
+A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should _ignore_. When relying on Babel configuration files you can only exclude additional files with this option, you cannot override what you have configured for Babel itself.
+
+### `include`
+
+Type: `String | RegExp | Array[...String|RegExp]`<br>
+
+A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should operate on. When relying on Babel configuration files you cannot include files already excluded there.
+
+### `filter`
+
+Type: (id: string) => boolean<br>
+
+Custom [filter function](https://github.com/rollup/plugins/tree/master/packages/pluginutils#createfilter) can be used to determine whether or not certain modules should be operated upon.
+
+Usage:
+
+```js
+import { createFilter } from '@rollup/pluginutils';
+const include = 'include/**.js';
+const exclude = 'exclude/**.js';
+const filter = createFilter(include, exclude, {});
+```
+
+### `extensions`
+
+Type: `Array[...String]`<br>
+Default: `['.js', '.jsx', '.es6', '.es', '.mjs']`
+
+An array of file extensions that Babel should transpile. If you want to transpile TypeScript files with this plugin it's essential to include `.ts` and `.tsx` in this option.
+
+### `babelHelpers`
+
+Type: `'bundled' | 'runtime' | 'inline' | 'external'`<br>
+Default: `'bundled'`
+
+It is recommended to configure this option explicitly (even if with its default value) so an informed decision is taken on how those babel helpers are inserted into the code.
+
+We recommend to follow these guidelines to determine the most appropriate value for your project:
+
+- `'runtime'` - you should use this especially when building libraries with Rollup. It has to be used in combination with `@babel/plugin-transform-runtime` and you should also specify `@babel/runtime` as dependency of your package. Don't forget to tell Rollup to treat the helpers imported from within the `@babel/runtime` module as external dependencies when bundling for `cjs` & `es` formats. This can be accomplished via regex (`external: [/@babel\/runtime/]`) or a function (`external: id => id.includes('@babel/runtime')`). It's important to not only specify `external: ['@babel/runtime']` since the helpers are imported from nested paths (e.g `@babel/runtime/helpers/get`) and [Rollup will only exclude modules that match strings exactly](https://rollupjs.org/guide/en/#peer-dependencies).
+- `'bundled'` - you should use this if you want your resulting bundle to contain those helpers (at most one copy of each). Useful especially if you bundle an application code.
+- `'external'` - use this only if you know what you are doing. It will reference helpers on **global** `babelHelpers` object. Used in combination with `@babel/plugin-external-helpers`.
+- `'inline'` - this is not recommended. Helpers will be inserted in each file using this option. This can cause serious code duplication. This is the default Babel behavior as Babel operates on isolated files - however, as Rollup is a bundler and is project-aware (and therefore likely operating across multiple input files), the default of this plugin is `"bundled"`.
+
+### `skipPreflightCheck`
+
+Type: `Boolean`<br>
+Default: `false`
+
+Before transpiling your input files this plugin also transpile a short piece of code **for each** input file. This is used to validate some misconfiguration errors, but for sufficiently big projects it can slow your build times so if you are confident about your configuration then you might disable those checks with this option.
+
+### External dependencies
+
+Ideally, you should only be transforming your source code, rather than running all of your external dependencies through Babel (to ignore external dependencies from being handled by this plugin you might use `exclude: 'node_modules/**'` option). If you have a dependency that exposes untranspiled ES6 source code that doesn't run in your target environment, then you may need to break this rule, but it often causes problems with unusual `.babelrc` files or mismatched versions of Babel.
+
+We encourage library authors not to distribute code that uses untranspiled ES6 features (other than modules) for this reason. Consumers of your library should _not_ have to transpile your ES6 code, any more than they should have to transpile your CoffeeScript, ClojureScript or TypeScript.
+
+Use `babelrc: false` to prevent Babel from using local (i.e. to your external dependencies) `.babelrc` files, relying instead on the configuration you pass in.
+
+### Helpers
+
+In some cases Babel uses _helpers_ to avoid repeating chunks of code – for example, if you use the `class` keyword, it will use a `classCallCheck` function to ensure that the class is instantiated correctly.
+
+By default, those helpers will be inserted at the top of the file being transformed, which can lead to duplication. This rollup plugin automatically deduplicates those helpers, keeping only one copy of each one used in the output bundle. Rollup will combine the helpers in a single block at the top of your bundle.
+
+You can customize how those helpers are being inserted into the transformed file with [`babelHelpers`](#babelhelpers) option.
+
+### Modules
+
+This is not needed since Babel 7 - it knows automatically that Rollup understands ES modules & that it shouldn't use any module transform with it. Unless you forcefully include a module transform in your Babel configuration.
+
+If you have been pointed to this section by an error thrown by this plugin, please check your Babel configuration files and disable any module transforms when running Rollup builds.
+
+## Running Babel on the generated code
+
+You can run `@rollup/plugin-babel` on the output files instead of the input files by using `getBabelOutputPlugin(...)`. This can be used to perform code transformations on the resulting chunks and is the only way to transform Rollup's auto-generated code. By default, the plugin will be applied to all outputs:
+
+```js
+// rollup.config.js
+import { getBabelOutputPlugin } from '@rollup/plugin-babel';
+
+export default {
+  input: 'main.js',
+  plugins: [
+    getBabelOutputPlugin({
+      presets: ['@babel/preset-env']
+    })
+  ],
+  output: [
+    { file: 'bundle.cjs.js', format: 'cjs' },
+    { file: 'bundle.esm.js', format: 'esm' }
+  ]
+};
+```
+
+If you only want to apply it to specific outputs, you can use it as an output plugin (requires at least Rollup v1.27.0):
+
+```js
+// rollup.config.js
+import { getBabelOutputPlugin } from '@rollup/plugin-babel';
+
+export default {
+  input: 'main.js',
+  output: [
+    { file: 'bundle.js', format: 'esm' },
+    {
+      file: 'bundle.es5.js',
+      format: 'esm',
+      plugins: [getBabelOutputPlugin({ presets: ['@babel/preset-env'] })]
+    }
+  ]
+};
+```
+
+The `include`, `exclude` and `extensions` options are ignored when the when using `getBabelOutputPlugin` and `createBabelOutputPluginFactory` will produce warnings, and there are a few more points to note that users should be aware of.
+
+You can also run the plugin twice on the code, once when processing the input files to transpile special syntax to JavaScript and once on the output to transpile to a lower compatibility target:
+
+```js
+// rollup.config.js
+import babel, { getBabelOutputPlugin } from '@rollup/plugin-babel';
+
+export default {
+  input: 'main.js',
+  plugins: [babel({ presets: ['@babel/preset-react'] })],
+  output: [
+    {
+      file: 'bundle.js',
+      format: 'esm',
+      plugins: [getBabelOutputPlugin({ presets: ['@babel/preset-env'] })]
+    }
+  ]
+};
+```
+
+### Babel configuration files
+
+Unlike the regular `babel` plugin, `getBabelOutputPlugin(...)` will **not** automatically search for [Babel configuration files](https://babeljs.io/docs/en/config-files). Besides passing in Babel options directly, however, you can specify a configuration file manually via Babel's [`configFile`](https://babeljs.io/docs/en/options#configfile) option:
+
+```js
+getBabelOutputPlugin({
+  configFile: path.resolve(__dirname, 'babel.config.js')
+});
+```
+
+### Using formats other than ES modules or CommonJS
+
+As `getBabelOutputPlugin(...)` will run _after_ Rollup has done all its transformations, it needs to make sure it preserves the semantics of Rollup's output format. This is especially important for Babel plugins that add, modify or remove imports or exports, but also for other transformations that add new variables as they can accidentally become global variables depending on the format. Therefore it is recommended that for formats other than `esm` or `cjs`, you set Rollup to use the `esm` output format and let Babel handle the transformation to another format, e.g. via
+
+```
+presets: [['@babel/preset-env', { modules: 'umd' }], ...]
+```
+
+to create a UMD/IIFE compatible output. If you want to use `getBabelOutputPlugin(...)` with other formats, you need to specify `allowAllFormats: true` as plugin option:
+
+```js
+rollup.rollup({...})
+.then(bundle => bundle.generate({
+  format: 'iife',
+  plugins: [getBabelOutputPlugin({
+    allowAllFormats: true,
+    // ...
+  })]
+}))
+```
+
+### Injected helpers
+
+By default, helpers e.g. when transpiling classes will be inserted at the top of each chunk. In contrast to when applying this plugin on the input files, helpers will not be deduplicated across chunks.
+
+Alternatively, you can use imported runtime helpers by adding the `@babel/transform-runtime` plugin. This will make `@babel/runtime` an external dependency of your project, see [@babel/plugin-transform-runtime](https://babeljs.io/docs/en/babel-plugin-transform-runtime) for details.
+
+Note that this will only work for `esm` and `cjs` formats, and you need to make sure to set the `useESModules` option of `@babel/plugin-transform-runtime` to `true` if you create ESM output:
+
+```js
+rollup.rollup({...})
+.then(bundle => bundle.generate({
+  format: 'esm',
+  plugins: [getBabelOutputPlugin({
+    presets: ['@babel/preset-env'],
+    plugins: [['@babel/plugin-transform-runtime', { useESModules: true }]]
+  })]
+}))
+```
+
+```js
+// input
+export default class Foo {}
+
+// output
+import _classCallCheck from '@babel/runtime/helpers/esm/classCallCheck';
+
+var Foo = function Foo() {
+  _classCallCheck(this, Foo);
+};
+
+export default Foo;
+```
+
+And for CommonJS:
+
+```js
+rollup.rollup({...})
+.then(bundle => bundle.generate({
+  format: 'cjs',
+  plugins: [getBabelOutputPlugin({
+    presets: ['@babel/preset-env'],
+    plugins: [['@babel/plugin-transform-runtime', { useESModules: false }]]
+  })]
+}))
+```
+
+```js
+// input
+export default class Foo {}
+
+// output
+('use strict');
+
+var _classCallCheck = require('@babel/runtime/helpers/classCallCheck');
+
+var Foo = function Foo() {
+  _classCallCheck(this, Foo);
+};
+
+module.exports = Foo;
+```
+
+Another option is to use `@babel/plugin-external-helpers`, which will reference the global `babelHelpers` object. It is your responsibility to make sure this global variable exists.
+
+## Custom plugin builder
+
+`@rollup/plugin-babel` exposes a plugin-builder utility that allows users to add custom handling of Babel's configuration for each file that it processes.
+
+`createBabelInputPluginFactory` accepts a callback that will be called with the loader's instance of `babel` so that tooling can ensure that it using exactly the same `@babel/core` instance as the loader itself.
+
+It's main purpose is to allow other tools for configuration of transpilation without forcing people to add extra configuration but still allow for using their own babelrc / babel config files.
+
+### Example
+
+```js
+import { createBabelInputPluginFactory } from '@rollup/plugin-babel';
+
+export default createBabelInputPluginFactory((babelCore) => {
+  function myPlugin() {
+    return {
+      visitor: {}
+    };
+  }
+
+  return {
+    // Passed the plugin options.
+    options({ opt1, opt2, ...pluginOptions }) {
+      return {
+        // Pull out any custom options that the plugin might have.
+        customOptions: { opt1, opt2 },
+
+        // Pass the options back with the two custom options removed.
+        pluginOptions
+      };
+    },
+
+    config(cfg /* Passed Babel's 'PartialConfig' object. */, { code, customOptions }) {
+      if (cfg.hasFilesystemConfig()) {
+        // Use the normal config
+        return cfg.options;
+      }
+
+      return {
+        ...cfg.options,
+        plugins: [
+          ...(cfg.options.plugins || []),
+
+          // Include a custom plugin in the options.
+          myPlugin
+        ]
+      };
+    },
+
+    result(result, { code, customOptions, config, transformOptions }) {
+      return {
+        ...result,
+        code: result.code + '\n// Generated by some custom plugin'
+      };
+    }
+  };
+});
+```

+# @rollup/plugin-replace
+
+🍣 A Rollup plugin which replaces targeted strings in files while bundling.
+
+## Requirements
+
+This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v8.0.0+) and Rollup v1.20.0+.
+
+## Install
+
+Using npm:
+
+```console
+npm install @rollup/plugin-replace --save-dev
+```
+
+## Usage
+
+Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
+
+```js
+import replace from '@rollup/plugin-replace';
+
+export default {
+  input: 'src/index.js',
+  output: {
+    dir: 'output',
+    format: 'cjs'
+  },
+  plugins: [
+    replace({
+      'process.env.NODE_ENV': JSON.stringify('production'),
+      __buildDate__: () => JSON.stringify(new Date()),
+      __buildVersion: 15
+    })
+  ]
+};
+```
+
+Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
+
+The configuration above will replace every instance of `process.env.NODE_ENV` with `"production"` and `__buildDate__` with the result of the given function in any file included in the build.
+
+_Note: Values must be either primitives (e.g. string, number) or `function` that returns a string. For complex values, use `JSON.stringify`. To replace a target with a value that will be evaluated as a string, set the value to a quoted string (e.g. `"test"`) or use `JSON.stringify` to preprocess the target string safely._
+
+Typically, `@rollup/plugin-replace` should be placed in `plugins` _before_ other plugins so that they may apply optimizations, such as dead code removal.
+
+## Options
+
+In addition to the properties and values specified for replacement, users may also specify the options below.
+
+### `delimiters`
+
+Type: `Array[...String, String]`<br>
+Default: `['\b', '\b']`
+
+Specifies the boundaries around which strings will be replaced. By default, delimiters are [word boundaries](https://www.regular-expressions.info/wordboundaries.html). See [Word Boundaries](#word-boundaries) below for more information.
+
+### `preventAssignment`
+
+Type: `Boolean`<br>
+Default: `false`
+
+Prevents replacing strings where they are followed by a single equals sign. For example, where the plugin is called as follows:
+
+```js
+replace({
+  values: {
+    'process.env.DEBUG': 'false'
+  }
+});
+```
+
+Observe the following code:
+
+```js
+// Input
+process.env.DEBUG = false;
+if (process.env.DEBUG == true) {
+  //
+}
+// Without `preventAssignment`
+false = false; // this throws an error because false cannot be assigned to
+if (false == true) {
+  //
+}
+// With `preventAssignment`
+process.env.DEBUG = false;
+if (false == true) {
+  //
+}
+```
+
+### `exclude`
+
+Type: `String` | `Array[...String]`<br>
+Default: `null`
+
+A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should _ignore_. By default no files are ignored.
+
+### `include`
+
+Type: `String` | `Array[...String]`<br>
+Default: `null`
+
+A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should operate on. By default all files are targeted.
+
+### `values`
+
+Type: `{ [key: String]: Replacement }`, where `Replacement` is either a string or a `function` that returns a string.
+Default: `{}`
+
+To avoid mixing replacement strings with the other options, you can specify replacements in the `values` option. For example, the following signature:
+
+```js
+replace({
+  include: ['src/**/*.js'],
+  changed: 'replaced'
+});
+```
+
+Can be replaced with:
+
+```js
+replace({
+  include: ['src/**/*.js'],
+  values: {
+    changed: 'replaced'
+  }
+});
+```
+
+## Word Boundaries
+
+By default, values will only match if they are surrounded by _word boundaries_.
+
+Consider the following options and build file:
+
+```js
+module.exports = {
+  ...
+  plugins: [replace({ changed: 'replaced' })]
+};
+```
+
+```js
+// file.js
+console.log('changed');
+console.log('unchanged');
+```
+
+The result would be:
+
+```js
+// file.js
+console.log('replaced');
+console.log('unchanged');
+```
+
+To ignore word boundaries and replace every instance of the string, wherever it may be, specify empty strings as delimiters:
+
+```js
+export default {
+  ...
+  plugins: [
+    replace({
+      changed: 'replaced',
+      delimiters: ['', '']
+    })
+  ]
+};
+```

+# @rollup/pluginutils
+
+A set of utility functions commonly used by 🍣 Rollup plugins.
+
+## Requirements
+
+This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v8.0.0+) and Rollup v1.20.0+.
+
+## Install
+
+Using npm:
+
+```console
+npm install @rollup/pluginutils --save-dev
+```
+
+## Usage
+
+```js
+import utils from '@rollup/pluginutils';
+//...
+```
+
+## API
+
+Available utility functions are listed below:
+
+_Note: Parameter names immediately followed by a `?` indicate that the parameter is optional._
+
+### addExtension
+
+Adds an extension to a module ID if one does not exist.
+
+Parameters: `(filename: String, ext?: String)`<br>
+Returns: `String`
+
+```js
+import { addExtension } from '@rollup/pluginutils';
+
+export default function myPlugin(options = {}) {
+  return {
+    resolveId(code, id) {
+      // only adds an extension if there isn't one already
+      id = addExtension(id); // `foo` -> `foo.js`, `foo.js -> foo.js`
+      id = addExtension(id, '.myext'); // `foo` -> `foo.myext`, `foo.js -> `foo.js`
+    }
+  };
+}
+```
+
+### attachScopes
+
+Attaches `Scope` objects to the relevant nodes of an AST. Each `Scope` object has a `scope.contains(name)` method that returns `true` if a given name is defined in the current scope or a parent scope.
+
+Parameters: `(ast: Node, propertyName?: String)`<br>
+Returns: `Object`
+
+See [rollup-plugin-inject](https://github.com/rollup/rollup-plugin-inject) or [rollup-plugin-commonjs](https://github.com/rollup/rollup-plugin-commonjs) for an example of usage.
+
+```js
+import { attachScopes } from '@rollup/pluginutils';
+import { walk } from 'estree-walker';
+
+export default function myPlugin(options = {}) {
+  return {
+    transform(code) {
+      const ast = this.parse(code);
+
+      let scope = attachScopes(ast, 'scope');
+
+      walk(ast, {
+        enter(node) {
+          if (node.scope) scope = node.scope;
+
+          if (!scope.contains('foo')) {
+            // `foo` is not defined, so if we encounter it,
+            // we assume it's a global
+          }
+        },
+        leave(node) {
+          if (node.scope) scope = scope.parent;
+        }
+      });
+    }
+  };
+}
+```
+
+### createFilter
+
+Constructs a filter function which can be used to determine whether or not certain modules should be operated upon.
+
+Parameters: `(include?: <minmatch>, exclude?: <minmatch>, options?: Object)`<br>
+Returns: `String`
+
+#### `include` and `exclude`
+
+Type: `String | RegExp | Array[...String|RegExp]`<br>
+
+A valid [`minimatch`](https://www.npmjs.com/package/minimatch) pattern, or array of patterns. If `options.include` is omitted or has zero length, filter will return `true` by default. Otherwise, an ID must match one or more of the `minimatch` patterns, and must not match any of the `options.exclude` patterns.
+
+#### `options`
+
+##### `resolve`
+
+Type: `String | Boolean | null`
+
+Optionally resolves the patterns against a directory other than `process.cwd()`. If a `String` is specified, then the value will be used as the base directory. Relative paths will be resolved against `process.cwd()` first. If `false`, then the patterns will not be resolved against any directory. This can be useful if you want to create a filter for virtual module names.
+
+#### Usage
+
+```js
+import { createFilter } from '@rollup/pluginutils';
+
+export default function myPlugin(options = {}) {
+  // assume that the myPlugin accepts options of `options.include` and `options.exclude`
+  var filter = createFilter(options.include, options.exclude, {
+    resolve: '/my/base/dir'
+  });
+
+  return {
+    transform(code, id) {
+      if (!filter(id)) return;
+
+      // proceed with the transformation...
+    }
+  };
+}
+```
+
+### dataToEsm
+
+Transforms objects into tree-shakable ES Module imports.
+
+Parameters: `(data: Object)`<br>
+Returns: `String`
+
+#### `data`
+
+Type: `Object`
+
+An object to transform into an ES module.
+
+#### Usage
+
+```js
+import { dataToEsm } from '@rollup/pluginutils';
+
+const esModuleSource = dataToEsm(
+  {
+    custom: 'data',
+    to: ['treeshake']
+  },
+  {
+    compact: false,
+    indent: '\t',
+    preferConst: false,
+    objectShorthand: false,
+    namedExports: true
+  }
+);
+/*
+Outputs the string ES module source:
+  export const custom = 'data';
+  export const to = ['treeshake'];
+  export default { custom, to };
+*/
+```
+
+### extractAssignedNames
+
+Extracts the names of all assignment targets based upon specified patterns.
+
+Parameters: `(param: Node)`<br>
+Returns: `Array[...String]`
+
+#### `param`
+
+Type: `Node`
+
+An `acorn` AST Node.
+
+#### Usage
+
+```js
+import { extractAssignedNames } from '@rollup/pluginutils';
+import { walk } from 'estree-walker';
+
+export default function myPlugin(options = {}) {
+  return {
+    transform(code) {
+      const ast = this.parse(code);
+
+      walk(ast, {
+        enter(node) {
+          if (node.type === 'VariableDeclarator') {
+            const declaredNames = extractAssignedNames(node.id);
+            // do something with the declared names
+            // e.g. for `const {x, y: z} = ... => declaredNames = ['x', 'z']
+          }
+        }
+      });
+    }
+  };
+}
+```
+
+### makeLegalIdentifier
+
+Constructs a bundle-safe identifier from a `String`.
+
+Parameters: `(str: String)`<br>
+Returns: `String`
+
+#### Usage
+
+```js
+import { makeLegalIdentifier } from '@rollup/pluginutils';
+
+makeLegalIdentifier('foo-bar'); // 'foo_bar'
+makeLegalIdentifier('typeof'); // '_typeof'
+```

+// Type definitions for ESTree AST specification
+// Project: https://github.com/estree/estree
+// Definitions by: RReverser <https://github.com/RReverser>
+// Definitions: https://github.com/DefinitelyTyped/DefinitelyTyped
+
+// This definition file follows a somewhat unusual format. ESTree allows
+// runtime type checks based on the `type` parameter. In order to explain this
+// to typescript we want to use discriminated union types:
+// https://github.com/Microsoft/TypeScript/pull/9163
+//
+// For ESTree this is a bit tricky because the high level interfaces like
+// Node or Function are pulling double duty. We want to pass common fields down
+// to the interfaces that extend them (like Identifier or
+// ArrowFunctionExpression), but you can't extend a type union or enforce
+// common fields on them. So we've split the high level interfaces into two
+// types, a base type which passes down inhereted fields, and a type union of
+// all types which extend the base type. Only the type union is exported, and
+// the union is how other types refer to the collection of inheriting types.
+//
+// This makes the definitions file here somewhat more difficult to maintain,
+// but it has the notable advantage of making ESTree much easier to use as
+// an end user.

+# estree-walker
+
+Simple utility for walking an [ESTree](https://github.com/estree/estree)-compliant AST, such as one generated by [acorn](https://github.com/marijnh/acorn).
+
+
+## Installation
+
+```bash
+npm i estree-walker
+```
+
+
+## Usage
+
+```js
+var walk = require( 'estree-walker' ).walk;
+var acorn = require( 'acorn' );
+
+ast = acorn.parse( sourceCode, options ); // https://github.com/acornjs/acorn
+
+walk( ast, {
+  enter: function ( node, parent, prop, index ) {
+    // some code happens
+  },
+  leave: function ( node, parent, prop, index ) {
+  	// some code happens
+  }
+});
+```
+
+Inside the `enter` function, calling `this.skip()` will prevent the node's children being walked, or the `leave` function (which is optional) being called.
+
+Call `this.replace(new_node)` in either `enter` or `leave` to replace the current node with a new one.
+
+Call `this.remove()` in either `enter` or `leave` to remove the current node.
+
+## Why not use estraverse?
+
+The ESTree spec is evolving to accommodate ES6/7. I've had a couple of experiences where [estraverse](https://github.com/estools/estraverse) was unable to handle an AST generated by recent versions of acorn, because it hard-codes visitor keys.
+
+estree-walker, by contrast, simply enumerates a node's properties to find child nodes (and child lists of nodes), and is therefore resistant to spec changes. It's also much smaller. (The performance, if you're wondering, is basically identical.)
+
+None of which should be taken as criticism of estraverse, which has more features and has been battle-tested in many more situations, and for which I'm very grateful.

+
+Suppose you have some source code. You want to make some light modifications to it - replacing a few characters here and there, wrapping it with a header and footer, etc - and ideally you'd like to generate a source map at the end of it. You've thought about using something like [recast](https://github.com/benjamn/recast) (which allows you to generate an AST from some JavaScript, manipulate it, and reprint it with a sourcemap without losing your comments and formatting), but it seems like overkill for your needs (or maybe the source code isn't JavaScript).
+
+Your requirements are, frankly, rather niche. But they're requirements that I also have, and for which I made magic-string. It's a small, fast utility for manipulating strings and generating sourcemaps.
+
+## Installation
+
+magic-string works in both node.js and browser environments. For node, install with npm:
+
+```bash
+npm i magic-string
+```
+
+To use in browser, grab the [magic-string.umd.js](https://unpkg.com/magic-string/dist/magic-string.umd.js) file and add it to your page:
+
+```html
+<script src='magic-string.umd.js'></script>
+```
+
+(It also works with various module systems, if you prefer that sort of thing - it has a dependency on [vlq](https://github.com/Rich-Harris/vlq).)
+
+## Usage
+
+These examples assume you're in node.js, or something similar:
+
+```js
+import MagicString from 'magic-string';
+import fs from 'fs'
+
+const s = new MagicString('problems = 99');
+
+s.overwrite(0, 8, 'answer');
+s.toString(); // 'answer = 99'
+
+s.overwrite(11, 13, '42'); // character indices always refer to the original string
+s.toString(); // 'answer = 42'
+
+s.prepend('var ').append(';'); // most methods are chainable
+s.toString(); // 'var answer = 42;'
+
+const map = s.generateMap({
+  source: 'source.js',
+  file: 'converted.js.map',
+  includeContent: true
+}); // generates a v3 sourcemap
+
+fs.writeFileSync('converted.js', s.toString());
+fs.writeFileSync('converted.js.map', map.toString());
+```
+
+You can pass an options argument:
+
+```js
+const s = new MagicString(someCode, {
+  // both these options will be used if you later
+  // call `bundle.addSource( s )` - see below
+  filename: 'foo.js',
+  indentExclusionRanges: [/*...*/]
+});
+```
+
+## Methods
+
+### s.addSourcemapLocation( index )
+
+Adds the specified character index (with respect to the original string) to sourcemap mappings, if `hires` is `false` (see below).
+
+### s.append( content )
+
+Appends the specified content to the end of the string. Returns `this`.
+
+### s.appendLeft( index, content )
+
+Appends the specified `content` at the `index` in the original string. If a range *ending* with `index` is subsequently moved, the insert will be moved with it. Returns `this`. See also `s.prependLeft(...)`.
+
+### s.appendRight( index, content )
+
+Appends the specified `content` at the `index` in the original string. If a range *starting* with `index` is subsequently moved, the insert will be moved with it. Returns `this`. See also `s.prependRight(...)`.
+
+### s.clone()
+
+Does what you'd expect.
+
+### s.generateDecodedMap( options )
+
+Generates a sourcemap object with raw mappings in array form, rather than encoded as a string. See `generateMap` documentation below for options details. Useful if you need to manipulate the sourcemap further, but most of the time you will use `generateMap` instead.
+
+### s.generateMap( options )
+
+Generates a [version 3 sourcemap](https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit). All options are, well, optional:
+
+* `file` - the filename where you plan to write the sourcemap
+* `source` - the filename of the file containing the original source
+* `includeContent` - whether to include the original content in the map's `sourcesContent` array
+* `hires` - whether the mapping should be high-resolution. Hi-res mappings map every single character, meaning (for example) your devtools will always be able to pinpoint the exact location of function calls and so on. With lo-res mappings, devtools may only be able to identify the correct line - but they're quicker to generate and less bulky. If sourcemap locations have been specified with `s.addSourceMapLocation()`, they will be used here.
+
+The returned sourcemap has two (non-enumerable) methods attached for convenience:
+
+* `toString` - returns the equivalent of `JSON.stringify(map)`
+* `toUrl` - returns a DataURI containing the sourcemap. Useful for doing this sort of thing:
+
+```js
+code += '\n//# sourceMappingURL=' + map.toUrl();
+```
+
+### s.indent( prefix[, options] )
+
+Prefixes each line of the string with `prefix`. If `prefix` is not supplied, the indentation will be guessed from the original content, falling back to a single tab character. Returns `this`.
+
+The `options` argument can have an `exclude` property, which is an array of `[start, end]` character ranges. These ranges will be excluded from the indentation - useful for (e.g.) multiline strings.
+
+### s.insertLeft( index, content )
+
+**DEPRECATED** since 0.17 – use `s.appendLeft(...)` instead
+
+### s.insertRight( index, content )
+
+**DEPRECATED** since 0.17 – use `s.prependRight(...)` instead
+
+### s.locate( index )
+
+**DEPRECATED** since 0.10 – see [#30](https://github.com/Rich-Harris/magic-string/pull/30)
+
+### s.locateOrigin( index )
+
+**DEPRECATED** since 0.10 – see [#30](https://github.com/Rich-Harris/magic-string/pull/30)
+
+### s.move( start, end, newIndex )
+
+Moves the characters from `start` and `end` to `index`. Returns `this`.
+
+### s.overwrite( start, end, content[, options] )
+
+Replaces the characters from `start` to `end` with `content`. The same restrictions as `s.remove()` apply. Returns `this`.
+
+The fourth argument is optional. It can have a `storeName` property — if `true`, the original name will be stored for later inclusion in a sourcemap's `names` array — and a `contentOnly` property which determines whether only the content is overwritten, or anything that was appended/prepended to the range as well.
+
+### s.prepend( content )
+
+Prepends the string with the specified content. Returns `this`.
+
+### s.prependLeft ( index, content )
+
+Same as `s.appendLeft(...)`, except that the inserted content will go *before* any previous appends or prepends at `index`
+
+### s.prependRight ( index, content )
+
+Same as `s.appendRight(...)`, except that the inserted content will go *before* any previous appends or prepends at `index`
+
+### s.remove( start, end )
+
+Removes the characters from `start` to `end` (of the original string, **not** the generated string). Removing the same content twice, or making removals that partially overlap, will cause an error. Returns `this`.
+
+### s.slice( start, end )
+
+Returns the content of the generated string that corresponds to the slice between `start` and `end` of the original string. Throws error if the indices are for characters that were already removed.
+
+### s.snip( start, end )
+
+Returns a clone of `s`, with all content before the `start` and `end` characters of the original string removed.
+
+### s.toString()
+
+Returns the generated string.
+
+### s.trim([ charType ])
+
+Trims content matching `charType` (defaults to `\s`, i.e. whitespace) from the start and end. Returns `this`.
+
+### s.trimStart([ charType ])
+
+Trims content matching `charType` (defaults to `\s`, i.e. whitespace) from the start. Returns `this`.
+
+### s.trimEnd([ charType ])
+
+Trims content matching `charType` (defaults to `\s`, i.e. whitespace) from the end. Returns `this`.
+
+### s.trimLines()
+
+Removes empty lines from the start and end. Returns `this`.
+
+### s.isEmpty()
+
+Returns true if the resulting source is empty (disregarding white space).
+
+## Bundling
+
+To concatenate several sources, use `MagicString.Bundle`:
+
+```js
+const bundle = new MagicString.Bundle();
+
+bundle.addSource({
+  filename: 'foo.js',
+  content: new MagicString('var answer = 42;')
+});
+
+bundle.addSource({
+  filename: 'bar.js',
+  content: new MagicString('console.log( answer )')
+});
+
+// Advanced: a source can include an `indentExclusionRanges` property
+// alongside `filename` and `content`. This will be passed to `s.indent()`
+// - see documentation above
+
+bundle.indent() // optionally, pass an indent string, otherwise it will be guessed
+  .prepend('(function () {\n')
+  .append('}());');
+
+bundle.toString();
+// (function () {
+//   var answer = 42;
+//   console.log( answer );
+// }());
+
+// options are as per `s.generateMap()` above
+const map = bundle.generateMap({
+  file: 'bundle.js',
+  includeContent: true,
+  hires: true
+});
+```
+
+As an alternative syntax, if you a) don't have `filename` or `indentExclusionRanges` options, or b) passed those in when you used `new MagicString(...)`, you can simply pass the `MagicString` instance itself:
+
+```js
+const bundle = new MagicString.Bundle();
+const source = new MagicString(someCode, {
+  filename: 'foo.js'
+});
+
+bundle.addSource(source);
+```

+<strong>Blazing fast and accurate glob matcher written in JavaScript.</strong></br>
+<em>No dependencies and full support for standard and extended Bash glob features, including braces, extglobs, POSIX brackets, and regular expressions.</em>
+</p>
+
+<br>
+<br>
+
+## Why picomatch?
+
+* **Lightweight** - No dependencies
+* **Minimal** - Tiny API surface. Main export is a function that takes a glob pattern and returns a matcher function.
+* **Fast** - Loads in about 2ms (that's several times faster than a [single frame of a HD movie](http://www.endmemo.com/sconvert/framespersecondframespermillisecond.php) at 60fps)
+* **Performant** - Use the returned matcher function to speed up repeat matching (like when watching files)
+* **Accurate matching** - Using wildcards (`*` and `?`), globstars (`**`) for nested directories, [advanced globbing](#advanced-globbing) with extglobs, braces, and POSIX brackets, and support for escaping special characters with `\` or quotes.
+* **Well tested** - Thousands of unit tests
+

+
+```sh
+npm install --save picomatch
+```
+

+
+## Usage
+
+The main export is a function that takes a glob pattern and an options object and returns a function for matching strings.
+
+```js
+const pm = require('picomatch');
+const isMatch = pm('*.js');
+
+console.log(isMatch('abcd')); //=> false
+console.log(isMatch('a.js')); //=> true

+## API
+
+### [picomatch](lib/picomatch.js#L32)
+
+Creates a matcher function from one or more glob patterns. The returned function takes a string to match as its first argument, and returns true if the string is a match. The returned matcher function also takes a boolean as the second argument that, when true, returns an object with additional information.

+
+```js
+const picomatch = require('picomatch');
+// picomatch(glob[, options]);
+
+const isMatch = picomatch('*.!(*a)');
+console.log(isMatch('a.a')); //=> false
+console.log(isMatch('a.b')); //=> true
+```
+
+### [.test](lib/picomatch.js#L117)

+// { isMatch: true, match: [ 'foo/', 'foo', 'bar' ], output: 'foo/bar' }
+```
+
+### [.matchBase](lib/picomatch.js#L161)
+
+Match the basename of a filepath.
+

+
+```js
+const picomatch = require('picomatch');
+// picomatch.matchBase(input, glob[, options]);
+console.log(picomatch.matchBase('foo/bar.js', '*.js'); // true
+```
+
+### [.isMatch](lib/picomatch.js#L183)
+
+Returns true if **any** of the given glob `patterns` match the specified `string`.
+
+**Params**
+
+* **{String|Array}**: str The string to test.
+* **{String|Array}**: patterns One or more glob patterns to use for matching.
+* **{Object}**: See available [options](#options).
+* `returns` **{Boolean}**: Returns true if any patterns match `str`
+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+// picomatch.isMatch(string, patterns[, options]);
+
+console.log(picomatch.isMatch('a.a', ['b.*', '*.a'])); //=> true
+console.log(picomatch.isMatch('a.a', 'b.*')); //=> false
+```
+
+### [.parse](lib/picomatch.js#L199)
+
+Parse a glob pattern to create the source string for a regular expression.
+
+**Params**
+
+* `pattern` **{String}**
+* `options` **{Object}**
+* `returns` **{Object}**: Returns an object with useful properties and output to be used as a regex source string.
+
+**Example**

+  isExtglob: false,
+  isGlobstar: false,
+  negated: true }
+```
+
+### [.compileRe](lib/picomatch.js#L245)

+Compile a regular expression from the `state` object returned by the
+[parse()](#parse) method.
+
+**Params**
+
+* `state` **{Object}**

+
+## Options
+
+### Picomatch options
+
+The following options may be used with the main `picomatch()` function or any of the methods on the picomatch API.
+
+| **Option** | **Type** | **Default value** | **Description** |
+| --- | --- | --- | --- |
+| `basename`            | `boolean`      | `false`     | If set, then patterns without slashes will be matched against the basename of the path if it contains slashes.  For example, `a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. |
+| `bash`                | `boolean`      | `false`     | Follow bash matching rules more strictly - disallows backslashes as escape characters, and treats single stars as globstars (`**`). |
+| `capture`             | `boolean`      | `undefined` | Return regex matches in supporting methods. |
+| `contains`            | `boolean`      | `undefined` | Allows glob to match any part of the given string(s). |
+| `cwd`                 | `string`       | `process.cwd()` | Current working directory. Used by `picomatch.split()` |
+| `debug`               | `boolean`      | `undefined` | Debug regular expressions when an error is thrown. |
+| `dot`                 | `boolean`      | `false`     | Enable dotfile matching. By default, dotfiles are ignored unless a `.` is explicitly defined in the pattern, or `options.dot` is true |
+| `expandRange`         | `function`     | `undefined` | Custom function for expanding ranges in brace patterns, such as `{a..z}`. The function receives the range values as two arguments, and it must return a string to be used in the generated regex. It's recommended that returned strings be wrapped in parentheses. |
+| `failglob`            | `boolean`      | `false`     | Throws an error if no matches are found. Based on the bash option of the same name. |
+| `fastpaths`           | `boolean`      | `true`      | To speed up processing, full parsing is skipped for a handful common glob patterns. Disable this behavior by setting this option to `false`. |
+| `flags`               | `string`      | `undefined` | Regex flags to use in the generated regex. If defined, the `nocase` option will be overridden. |
+| [format](#optionsformat) | `function` | `undefined` | Custom function for formatting the returned string. This is useful for removing leading slashes, converting Windows paths to Posix paths, etc. |
+| `ignore`              | `array\|string` | `undefined` | One or more glob patterns for excluding strings that should not be matched from the result. |
+| `keepQuotes`          | `boolean`      | `false`     | Retain quotes in the generated regex, since quotes may also be used as an alternative to backslashes.  |
+| `literalBrackets`     | `boolean`      | `undefined` | When `true`, brackets in the glob pattern will be escaped so that only literal brackets will be matched. |
+| `matchBase`           | `boolean`      | `false`     | Alias for `basename` |
+| `maxLength`           | `number`      | `65536`     | Limit the max length of the input string. An error is thrown if the input string is longer than this value. |
+| `maxExtglobRecursion` | `number\|boolean` | `0` | Limit nested quantified extglobs and other risky repeated extglob forms. When the limit is exceeded, the extglob is treated as a literal string instead of being compiled to regex. Set to `false` to disable this safeguard. |
+| `nobrace`             | `boolean`      | `false`     | Disable brace matching, so that `{a,b}` and `{1..3}` would be treated as literal characters. |
+| `nobracket`           | `boolean`      | `undefined` | Disable matching with regex brackets. |
+| `nocase`              | `boolean`      | `false`     | Make matching case-insensitive. Equivalent to the regex `i` flag. Note that this option is overridden by the `flags` option. |
+| `nodupes`             | `boolean`      | `true`      | Deprecated, use `nounique` instead. This option will be removed in a future major release. By default duplicates are removed. Disable uniquification by setting this option to false. |
+| `noext`               | `boolean`      | `false`     | Alias for `noextglob` |

+
+picomatch has automatic detection for regex positive and negative lookbehinds. If the pattern contains a negative lookbehind, you must be using Node.js >= 8.10 or else picomatch will throw an error.
+
+### Scan Options
+
+In addition to the main [picomatch options](#picomatch-options), the following options may also be used with the [.scan](#scan) method.
+
+| **Option** | **Type** | **Default value** | **Description** |
+| --- | --- | --- | --- |
+| `tokens` | `boolean` | `false` | When `true`, the returned object will include an array of tokens (objects), representing each path "segment" in the scanned glob pattern |
+| `parts` | `boolean` | `false` | When `true`, the returned object will include an array of strings representing each path "segment" in the scanned glob pattern. This is automatically enabled when `options.tokens` is true |
+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+const result = picomatch.scan('!./foo/*.js', { tokens: true });
+console.log(result);
+// {
+//   prefix: '!./',
+//   input: '!./foo/*.js',
+//   start: 3,
+//   base: 'foo',
+//   glob: '*.js',
+//   isBrace: false,
+//   isBracket: false,
+//   isGlob: true,
+//   isExtglob: false,
+//   isGlobstar: false,
+//   negated: true,
+//   maxDepth: 2,
+//   tokens: [
+//     { value: '!./', depth: 0, isGlob: false, negated: true, isPrefix: true },
+//     { value: 'foo', depth: 1, isGlob: false },
+//     { value: '*.js', depth: 1, isGlob: true }
+//   ],
+//   slashes: [ 2, 6 ],
+//   parts: [ 'foo', '*.js' ]
+// }
+```
+
+<br>
+
+### Options Examples
+
+#### options.expandRange
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Custom function for expanding ranges in brace patterns. The [fill-range](https://github.com/jonschlinkert/fill-range) library is ideal for this purpose, or you can use custom code to do whatever you need.
+
+**Example**
+
+The following example shows how to create a glob that matches a folder
+
+```js
+const fill = require('fill-range');
+const regex = pm.makeRe('foo/{01..25}/bar', {
+  expandRange(a, b) {
+    return `(${fill(a, b, { toRegex: true })})`;
+  }
+});
+
+console.log(regex);
+//=> /^(?:foo\/((?:0[1-9]|1[0-9]|2[0-5]))\/bar)$/
+
+console.log(regex.test('foo/00/bar'))  // false
+console.log(regex.test('foo/01/bar'))  // true
+console.log(regex.test('foo/10/bar')) // true
+console.log(regex.test('foo/22/bar')) // true
+console.log(regex.test('foo/25/bar')) // true
+console.log(regex.test('foo/26/bar')) // false
+```
+
+#### options.format
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Custom function for formatting strings before they're matched.
+
+**Example**
+
+```js
+// strip leading './' from strings
+const format = str => str.replace(/^\.\//, '');
+const isMatch = picomatch('foo/*.js', { format });
+console.log(isMatch('./foo/bar.js')); //=> true
+```
+
+#### options.onMatch
+
+```js
+const onMatch = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onMatch });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```
+
+#### options.onIgnore
+
+```js
+const onIgnore = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onIgnore, ignore: 'f*' });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```
+
+#### options.onResult
+
+```js
+const onResult = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onResult, ignore: 'f*' });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```

+## Globbing features
+
+* [Basic globbing](#basic-globbing) (Wildcard matching)
+* [Advanced globbing](#advanced-globbing) (extglobs, posix brackets, brace matching)
+
+### Basic globbing
+
+| **Character** | **Description** |
+| --- | --- |
+| `*` | Matches any character zero or more times, excluding path separators. Does _not match_ path separators or hidden files or directories ("dotfiles"), unless explicitly enabled by setting the `dot` option to `true`. |
+| `**` | Matches any character zero or more times, including path separators. Note that `**` will only match path separators (`/`, and `\\` on Windows) when they are the only characters in a path segment. Thus, `foo**/bar` is equivalent to `foo*/bar`, and `foo/a**b/bar` is equivalent to `foo/a*b/bar`, and _more than two_ consecutive stars in a glob path segment are regarded as _a single star_. Thus, `foo/***/bar` is equivalent to `foo/*/bar`. |
+| `?` | Matches any character excluding path separators one time. Does _not match_ path separators or leading dots.  |
+| `[abc]` | Matches any characters inside the brackets. For example, `[abc]` would match the characters `a`, `b` or `c`, and nothing else. |
+
+#### Matching behavior vs. Bash
+
+Picomatch's matching features and expected results in unit tests are based on Bash's unit tests and the Bash 4.3 specification, with the following exceptions:
+
+* Bash will match `foo/bar/baz` with `*`. Picomatch only matches nested directories with `**`.
+* Bash greedily matches with negated extglobs. For example, Bash 4.3 says that `!(foo)*` should match `foo` and `foobar`, since the trailing `*` bracktracks to match the preceding pattern. This is very memory-inefficient, and IMHO, also incorrect. Picomatch would return `false` for both `foo` and `foobar`.
+
+<br>
+
+### Advanced globbing
+
+* [extglobs](#extglobs)
+* [POSIX brackets](#posix-brackets)
+* [Braces](#brace-expansion)
+
+#### Extglobs
+
+| **Pattern** | **Description** |
+| --- | --- |
+| `@(pattern)` | Match _only one_ consecutive occurrence of `pattern` |
+| `*(pattern)` | Match _zero or more_ consecutive occurrences of `pattern` |
+| `+(pattern)` | Match _one or more_ consecutive occurrences of `pattern` |
+| `?(pattern)` | Match _zero or **one**_ consecutive occurrences of `pattern` |
+| `!(pattern)` | Match _anything but_ `pattern` |
+
+**Examples**
+
+```js
+const pm = require('picomatch');
+
+// *(pattern) matches ZERO or more of "pattern"
+console.log(pm.isMatch('a', 'a*(z)')); // true
+console.log(pm.isMatch('az', 'a*(z)')); // true
+console.log(pm.isMatch('azzz', 'a*(z)')); // true
+
+// +(pattern) matches ONE or more of "pattern"
+console.log(pm.isMatch('a', 'a*(z)')); // true
+console.log(pm.isMatch('az', 'a*(z)')); // true
+console.log(pm.isMatch('azzz', 'a*(z)')); // true
+
+// supports multiple extglobs
+console.log(pm.isMatch('foo.bar', '!(foo).!(bar)')); // false
+
+// supports nested extglobs
+console.log(pm.isMatch('foo.bar', '!(!(foo)).!(!(bar))')); // true
+
+// risky quantified extglobs are treated literally by default
+console.log(pm.makeRe('+(a|aa)'));
+//=> /^(?:\+\(a\|aa\))$/
+
+// increase the limit to allow a small amount of nested quantified extglobs
+console.log(pm.isMatch('aaa', '+(+(a))', { maxExtglobRecursion: 1 })); // true
+```
+
+#### POSIX brackets
+
+POSIX classes are disabled by default. Enable this feature by setting the `posix` option to true.
+
+**Enable POSIX bracket support**
+
+```js
+console.log(pm.makeRe('[[:word:]]+', { posix: true }));
+//=> /^(?:(?=.)[A-Za-z0-9_]+\/?)$/
+```
+
+**Supported POSIX classes**
+
+The following named POSIX bracket expressions are supported:
+
+* `[:alnum:]` - Alphanumeric characters, equ `[a-zA-Z0-9]`
+* `[:alpha:]` - Alphabetical characters, equivalent to `[a-zA-Z]`.
+* `[:ascii:]` - ASCII characters, equivalent to `[\\x00-\\x7F]`.
+* `[:blank:]` - Space and tab characters, equivalent to `[ \\t]`.
+* `[:cntrl:]` - Control characters, equivalent to `[\\x00-\\x1F\\x7F]`.
+* `[:digit:]` - Numerical digits, equivalent to `[0-9]`.
+* `[:graph:]` - Graph characters, equivalent to `[\\x21-\\x7E]`.
+* `[:lower:]` - Lowercase letters, equivalent to `[a-z]`.
+* `[:print:]` - Print characters, equivalent to `[\\x20-\\x7E ]`.
+* `[:punct:]` - Punctuation and symbols, equivalent to `[\\-!"#$%&\'()\\*+,./:;<=>?@[\\]^_`{|}~]`.
+* `[:space:]` - Extended space characters, equivalent to `[ \\t\\r\\n\\v\\f]`.
+* `[:upper:]` - Uppercase letters, equivalent to `[A-Z]`.
+* `[:word:]` -  Word characters (letters, numbers and underscores), equivalent to `[A-Za-z0-9_]`.
+* `[:xdigit:]` - Hexadecimal digits, equivalent to `[A-Fa-f0-9]`.
+
+See the [Bash Reference Manual](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html) for more information.
+
+### Braces
+
+Picomatch does not do brace expansion. For [brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html) and advanced matching with braces, use [micromatch](https://github.com/micromatch/micromatch) instead. Picomatch has very basic support for braces.
+
+### Matching special characters as literals
+
+If you wish to match the following special characters in a filepath, and you want to use these characters in your glob pattern, they must be escaped with backslashes or quotes:
+
+**Special Characters**
+
+Some characters that are used for matching in regular expressions are also regarded as valid file path characters on some platforms.
+
+To match any of the following characters as literals: `$^*+?()[]
+
+Examples:
+
+```js
+console.log(pm.makeRe('foo/bar \\(1\\)'));
+console.log(pm.makeRe('foo/bar \\(1\\)'));
+```
+

+
+## Philosophies
+
+The goal of this library is to be blazing fast, without compromising on accuracy.
+
+**Accuracy**
+
+The number one of goal of this library is accuracy. However, it's not unusual for different glob implementations to have different rules for matching behavior, even with simple wildcard matching. It gets increasingly more complicated when combinations of different features are combined, like when extglobs are combined with globstars, braces, slashes, and so on: `!(**/{a,b,*/c})`.
+
+Thus, given that there is no canonical glob specification to use as a single source of truth when differences of opinion arise regarding behavior, sometimes we have to implement our best judgement and rely on feedback from users to make improvements.
+
+**Performance**
+
+Although this library performs well in benchmarks, and in most cases it's faster than other popular libraries we benchmarked against, we will always choose accuracy over performance. It's not helpful to anyone if our library is faster at returning the wrong answer.

+# pretty-bytes
+
+> Convert bytes to a human readable string: `1337` → `1.34 kB`
+
+Useful for displaying file sizes for humans.
+
+*Note that it uses base-10 (e.g. kilobyte).
+[Read about the difference between kilobyte and kibibyte.](https://web.archive.org/web/20150324153922/https://pacoup.com/2009/05/26/kb-kb-kib-whats-up-with-that/)*
+
+## Install
+
+```
+$ npm install pretty-bytes
+```
+
+## Usage
+
+```js
+const prettyBytes = require('pretty-bytes');
+
+prettyBytes(1337);
+//=> '1.34 kB'
+
+prettyBytes(100);
+//=> '100 B'
+
+// Display with units of bits
+prettyBytes(1337, {bits: true});
+//=> '1.34 kbit'
+
+// Display file size differences
+prettyBytes(42, {signed: true});
+//=> '+42 B'
+
+// Localized output using German locale
+prettyBytes(1337, {locale: 'de'});
+//=> '1,34 kB'
+```
+
+## API
+
+### prettyBytes(number, options?)
+
+#### number
+
+Type: `number`
+
+The number to format.
+
+#### options
+
+Type: `object`
+
+##### signed
+
+Type: `boolean`\
+Default: `false`
+
+Include plus sign for positive numbers. If the difference is exactly zero a space character will be prepended instead for better alignment.
+
+##### bits
+
+Type: `boolean`\
+Default: `false`
+
+Format the number as [bits](https://en.wikipedia.org/wiki/Bit) instead of [bytes](https://en.wikipedia.org/wiki/Byte). This can be useful when, for example, referring to [bit rate](https://en.wikipedia.org/wiki/Bit_rate).
+
+##### binary
+
+Type: `boolean`\
+Default: `false`
+
+Format the number using the [Binary Prefix](https://en.wikipedia.org/wiki/Binary_prefix) instead of the [SI Prefix](https://en.wikipedia.org/wiki/SI_prefix). This can be useful for presenting memory amounts. However, this should not be used for presenting file sizes.
+
+##### locale
+
+Type: `boolean | string`\
+Default: `false` *(No localization)*
+
+**Important:** Only the number and decimal separator are localized. The unit title is not and will not be localized.
+
+- If `true`: Localize the output using the system/browser locale.
+- If `string`: Expects a [BCP 47 language tag](https://en.wikipedia.org/wiki/IETF_language_tag) (For example: `en`, `de`, …)
+- If `string[]`: Expects a list of [BCP 47 language tags](https://en.wikipedia.org/wiki/IETF_language_tag) (For example: `en`, `de`, …)
+
+**Note:** Localization should generally work in browsers. Node.js needs to be [built](https://github.com/nodejs/node/wiki/Intl) with `full-icu` or `system-icu`. Alternatively, the [`full-icu`](https://github.com/unicode-org/full-icu-npm) module can be used to provide support at runtime. [Node.js 13](https://nodejs.org/en/blog/release/v13.0.0/) and later ships with ICU by default.
+
+##### minimumFractionDigits
+
+Type: `number`\
+Default: `undefined`
+
+The minimum number of fraction digits to display.
+
+If neither `minimumFractionDigits` or `maximumFractionDigits` are set, the default behavior is to round to 3 significant digits.
+
+```js
+const prettyBytes = require('pretty-bytes');
+
+// Show the number with at least 3 fractional digits
+prettyBytes(1900, {minimumFractionDigits: 3});
+//=> '1.900 kB'
+
+prettyBytes(1900);
+//=> '1.9 kB'
+```
+
+##### maximumFractionDigits
+
+Type: `number`\
+Default: `undefined`
+
+The maximum number of fraction digits to display.
+
+If neither `minimumFractionDigits` or `maximumFractionDigits` are set, the default behavior is to round to 3 significant digits.
+
+```js
+const prettyBytes = require('pretty-bytes');
+
+// Show the number with at most 1 fractional digit
+prettyBytes(1920, {maximumFractionDigits: 1});
+//=> '1.9 kB'
+
+prettyBytes(1920);
+//=> '1.92 kB'
+```

+<h1 align="center">Rollup</h1>
+
+## Overview
+
+Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the standardized ES module format for code, instead of previous idiosyncratic solutions such as CommonJS and AMD. ES modules let you freely and seamlessly combine the most useful individual functions from your favorite libraries. Rollup can optimize ES modules for faster native loading in modern browsers, or output a legacy module format allowing ES module workflows today.
+
+## Quick Start Guide
+
+Install with `npm install --global rollup`. Rollup can be used either through a [command line interface](https://rollupjs.org/#command-line-reference) with an optional configuration file or else through its [JavaScript API](https://rollupjs.org/guide/en/#javascript-api). Run `rollup --help` to see the available options and parameters. The starter project templates, [rollup-starter-lib](https://github.com/rollup/rollup-starter-lib) and [rollup-starter-app](https://github.com/rollup/rollup-starter-app), demonstrate common configuration options, and more detailed instructions are available throughout the [user guide](https://rollupjs.org/).
+
+### Commands
+
+These commands assume the entry point to your application is named main.js, and that you'd like all imports compiled into a single file named bundle.js.
+
+For browsers:
+
+```bash
+# compile to a <script> containing a self-executing function
+rollup main.js --format iife --name "myBundle" --file bundle.js
+```
+
+For Node.js:
+
+```bash
+# compile to a CommonJS module
+rollup main.js --format cjs --file bundle.js
+```
+
+For both browsers and Node.js:
+
+```bash
+# UMD format requires a bundle name
+rollup main.js --format umd --name "myBundle" --file bundle.js
+```
+
+## Why
+
+Developing software is usually easier if you break your project into smaller separate pieces, since that often removes unexpected interactions and dramatically reduces the complexity of the problems you'll need to solve, and simply writing smaller projects in the first place [isn't necessarily the answer](https://medium.com/@Rich_Harris/small-modules-it-s-not-quite-that-simple-3ca532d65de4). Unfortunately, JavaScript has not historically included this capability as a core feature in the language.
+
+This finally changed with ES modules support in JavaScript, which provides a syntax for importing and exporting functions and data so they can be shared between separate scripts. Most browsers and Node.js support ES modules. However, Node.js releases before 12.17 support ES modules only behind the `--experimental-modules` flag, and older browsers like Internet Explorer do not support ES modules at all. Rollup allows you to write your code using ES modules, and run your application even in environments that do not support ES modules natively. For environments that support them, Rollup can output optimized ES modules; for environments that don't, Rollup can compile your code to other formats such as CommonJS modules, AMD modules, and IIFE-style scripts. This means that you get to _write future-proof code_, and you also get the tremendous benefits of...
+
+## Tree Shaking
+
+In addition to enabling the use of ES modules, Rollup also statically analyzes and optimizes the code you are importing, and will exclude anything that isn't actually used. This allows you to build on top of existing tools and modules without adding extra dependencies or bloating the size of your project.
+
+For example, with CommonJS, the _entire tool or library must be imported_.
+
+```js
+// import the entire utils object with CommonJS
+var utils = require('utils');
+var query = 'Rollup';
+// use the ajax method of the utils object
+utils.ajax('https://api.example.com?search=' + query).then(handleResponse);
+```
+
+But with ES modules, instead of importing the whole `utils` object, we can just import the one `ajax` function we need:
+
+```js
+// import the ajax function with an ES import statement
+import { ajax } from 'utils';
+var query = 'Rollup';
+// call the ajax function
+ajax('https://api.example.com?search=' + query).then(handleResponse);
+```
+
+Because Rollup includes the bare minimum, it results in lighter, faster, and less complicated libraries and applications. Since this approach is based on explicit `import` and `export` statements, it is vastly more effective than simply running an automated minifier to detect unused variables in the compiled output code.
+
+## Compatibility
+
+### Importing CommonJS
+
+Rollup can import existing CommonJS modules [through a plugin](https://github.com/rollup/plugins/tree/master/packages/commonjs).
+
+### Publishing ES Modules
+
+To make sure your ES modules are immediately usable by tools that work with CommonJS such as Node.js and webpack, you can use Rollup to compile to UMD or CommonJS format, and then point to that compiled version with the `main` property in your `package.json` file. If your `package.json` file also has a `module` field, ES-module-aware tools like Rollup and [webpack](https://webpack.js.org/) will [import the ES module version](https://github.com/rollup/rollup/wiki/pkg.module) directly.

+# Change Log
+
+## 0.8.0-beta.0
+
+### Breaking changes
+
+* [#350](https://github.com/mozilla/source-map/pull/350) -
+  Change browser detection logic for WASM loading.
+* [#363](https://github.com/mozilla/source-map/pull/363) -
+  Change WASM loading detection to rely on `package.json#browser` field.
+* [#362](https://github.com/mozilla/source-map/pull/362) -
+  Remove the `dist/` bundle.
+* [#371](https://github.com/mozilla/source-map/pull/371) -
+  Reimplement sourcemap URL processing using the WHATWG URL API.
+
+### Nonbreaking changes:
+
+* [#339](https://github.com/mozilla/source-map/pull/339) -
+  Allow initializing the consumer `mappings.wasm` file as an `ArrayBuffer`.
+
+### Internal Improvements:
+
+* [#347](https://github.com/mozilla/source-map/pull/347) -
+  Improve tests.
+* [#352](https://github.com/mozilla/source-map/pull/352) -
+  Improve documentation.
+* [#361](https://github.com/mozilla/source-map/pull/361) -
+  Use newer Webpack CLI when bundling.
+* [#364](https://github.com/mozilla/source-map/pull/364) -
+  Convert `IndexedSourceMapConsumer` implementation to pass more through
+    to `BasicSourceMapConsumer`.
+* [#366](https://github.com/mozilla/source-map/pull/366) -
+  Normalize internal URL representation to be easier to follow.
+* [#341](https://github.com/mozilla/source-map/pull/341) -
+  Use async functions to simplify `SourceMapConsumer.with` implementation.
+
+
+## 0.7.3
+
+* Fix a bug where nested uses of `SourceMapConsumer` could result in a
+  `TypeError`. [#338](https://github.com/mozilla/source-map/issues/338)
+  [#330](https://github.com/mozilla/source-map/issues/330)
+  [#319](https://github.com/mozilla/source-map/issues/319)
+
+## 0.7.2
+
+* Another 3x speed up in `SourceMapConsumer`. Read about it here:
+  http://fitzgeraldnick.com/2018/02/26/speed-without-wizardry.html
+
+## 0.7.1
+
+* Updated TypeScript typings. [#321][]
+
+[#321]: https://github.com/mozilla/source-map/pull/321
+
+## 0.7.0
+
+* `SourceMapConsumer` now uses WebAssembly, and is **much** faster! Read about
+  it here:
+  https://hacks.mozilla.org/2018/01/oxidizing-source-maps-with-rust-and-webassembly/
+
+* **Breaking change:** `new SourceMapConsumer` now returns a `Promise` object
+  that resolves to the newly constructed `SourceMapConsumer` instance, rather
+  than returning the new instance immediately.
+
+* **Breaking change:** when you're done using a `SourceMapConsumer` instance,
+  you must call `SourceMapConsumer.prototype.destroy` on it. After calling
+  `destroy`, you must not use the instance again.
+
+* **Breaking change:** `SourceMapConsumer` used to be able to handle lines,
+  columns numbers and source and name indices up to `2^53 - 1` (aka
+  `Number.MAX_SAFE_INTEGER`). It can now only handle them up to `2^32 - 1`.
+
+* **Breaking change:** The `source-map` library now uses modern ECMAScript-isms:
+  `let`, arrow functions, `async`, etc. Use Babel to compile it down to
+  ECMAScript 5 if you need to support older JavaScript environments.
+
+* **Breaking change:** Drop support for Node < 8. If you want to support older
+versions of node, please use v0.6 or below.
+
+## 0.5.6
+
+* Fix for regression when people were using numbers as names in source maps. See
+  #236.
+
+## 0.5.5
+
+* Fix "regression" of unsupported, implementation behavior that half the world
+  happens to have come to depend on. See #235.
+
+* Fix regression involving function hoisting in SpiderMonkey. See #233.
+
+## 0.5.4
+
+* Large performance improvements to source-map serialization. See #228 and #229.
+
+## 0.5.3
+
+* Do not include unnecessary distribution files. See
+  commit ef7006f8d1647e0a83fdc60f04f5a7ca54886f86.
+
+## 0.5.2
+
+* Include browser distributions of the library in package.json's `files`. See
+  issue #212.
+
+## 0.5.1
+
+* Fix latent bugs in IndexedSourceMapConsumer.prototype._parseMappings. See
+  ff05274becc9e6e1295ed60f3ea090d31d843379.
+
+## 0.5.0
+
+* Node 0.8 is no longer supported.
+
+* Use webpack instead of dryice for bundling.
+
+* Big speedups serializing source maps. See pull request #203.
+
+* Fix a bug with `SourceMapConsumer.prototype.sourceContentFor` and sources that
+  explicitly start with the source root. See issue #199.
+
+## 0.4.4
+
+* Fix an issue where using a `SourceMapGenerator` after having created a
+  `SourceMapConsumer` from it via `SourceMapConsumer.fromSourceMap` failed. See
+  issue #191.
+
+* Fix an issue with where `SourceMapGenerator` would mistakenly consider
+  different mappings as duplicates of each other and avoid generating them. See
+  issue #192.
+
+## 0.4.3
+
+* A very large number of performance improvements, particularly when parsing
+  source maps. Collectively about 75% of time shaved off of the source map
+  parsing benchmark!
+
+* Fix a bug in `SourceMapConsumer.prototype.allGeneratedPositionsFor` and fuzzy
+  searching in the presence of a column option. See issue #177.
+
+* Fix a bug with joining a source and its source root when the source is above
+  the root. See issue #182.
+
+* Add the `SourceMapConsumer.prototype.hasContentsOfAllSources` method to
+  determine when all sources' contents are inlined into the source map. See
+  issue #190.
+
+## 0.4.2
+
+* Add an `.npmignore` file so that the benchmarks aren't pulled down by
+  dependent projects. Issue #169.
+
+* Add an optional `column` argument to
+  `SourceMapConsumer.prototype.allGeneratedPositionsFor` and better handle lines
+  with no mappings. Issues #172 and #173.
+
+## 0.4.1
+
+* Fix accidentally defining a global variable. #170.
+
+## 0.4.0
+
+* The default direction for fuzzy searching was changed back to its original
+  direction. See #164.
+
+* There is now a `bias` option you can supply to `SourceMapConsumer` to control
+  the fuzzy searching direction. See #167.
+
+* About an 8% speed up in parsing source maps. See #159.
+
+* Added a benchmark for parsing and generating source maps.
+
+## 0.3.0
+
+* Change the default direction that searching for positions fuzzes when there is
+  not an exact match. See #154.
+
+* Support for environments using json2.js for JSON serialization. See #156.
+
+## 0.2.0
+
+* Support for consuming "indexed" source maps which do not have any remote
+  sections. See pull request #127. This introduces a minor backwards
+  incompatibility if you are monkey patching `SourceMapConsumer.prototype`
+  methods.
+
+## 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
+
+* Fixed a bug where SourceMapConsumer couldn't handle negative relative columns
+  (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
+
+* Delay parsing the mappings in SourceMapConsumer until queried for a source
+  location.
+
+* Support Sass source maps (which at the time of writing deviate from the spec
+  in small ways) in SourceMapConsumer.
+
+## 0.1.30
+
+* Do not join source root with a source, when the source is a data URI.
+
+* Extend the test runner to allow running single specific test files at a time.
+
+* Performance improvements in `SourceNode.prototype.walk` and
+  `SourceMapConsumer.prototype.eachMapping`.
+
+* Source map browser builds will now work inside Workers.
+
+* Better error messages when attempting to add an invalid mapping to a
+  `SourceMapGenerator`.
+
+## 0.1.29
+
+* Allow duplicate entries in the `names` and `sources` arrays of source maps
+  (usually from TypeScript) we are parsing. Fixes github issue 72.
+
+## 0.1.28
+
+* Skip duplicate mappings when creating source maps from SourceNode; github
+  issue 75.
+
+## 0.1.27
+
+* Don't throw an error when the `file` property is missing in SourceMapConsumer,
+  we don't use it anyway.
+
+## 0.1.26
+
+* Fix SourceNode.fromStringWithSourceMap for empty maps. Fixes github issue 70.
+
+## 0.1.25
+

+
+### 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)
+
+```js
+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)
+
+```js
+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:
+
+```js
+// Node.js
+var sourceMap = require('source-map');
+
+// Browser builds
+var sourceMap = window.sourceMap;
+
+// Inside Firefox
+const sourceMap = require("devtools/toolkit/sourcemap/source-map.js");
+```
+
+### 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.
+
+#### SourceMapConsumer.initialize(options)
+
+When using `SourceMapConsumer` outside of node.js, for example on the Web, it
+needs to know from what URL to load `lib/mappings.wasm`. You must inform it by
+calling `initialize` before constructing any `SourceMapConsumer`s.
+
+The options object has the following properties:
+
+* `"lib/mappings.wasm"`: A `String` containing the URL of the
+  `lib/mappings.wasm` file, or an `ArrayBuffer` with the contents of `lib/mappings.wasm`.
+
+```js
+sourceMap.SourceMapConsumer.initialize({
+  "lib/mappings.wasm": "https://example.com/source-map/lib/mappings.wasm"
+});
+```
+
+#### 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 referenced 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.
+
+The promise of the constructed souce map consumer is returned.
+
+When the `SourceMapConsumer` will no longer be used anymore, you must call its
+`destroy` method.
+
+```js
+const consumer = await new sourceMap.SourceMapConsumer(rawSourceMapJsonData);
+doStuffWith(consumer);
+consumer.destroy();
+```
+
+Alternatively, you can use `SourceMapConsumer.with` to avoid needing to remember
+to call `destroy`.
+
+#### SourceMapConsumer.with
+
+Construct a new `SourceMapConsumer` from `rawSourceMap` and `sourceMapUrl`
+(see the `SourceMapConsumer` constructor for details. Then, invoke the `async
+function f(SourceMapConsumer) -> T` with the newly constructed consumer, wait
+for `f` to complete, call `destroy` on the consumer, and return `f`'s return
+value.
+
+You must not use the consumer after `f` completes!
+
+By using `with`, you do not have to remember to manually call `destroy` on
+the consumer, since it will be called automatically once `f` completes.
+
+```js
+const xSquared = await SourceMapConsumer.with(
+  myRawSourceMap,
+  null,
+  async function (consumer) {
+    // Use `consumer` inside here and don't worry about remembering
+    // to call `destroy`.
+
+    const x = await whatever(consumer);
+    return x * x;
+  }
+);
+
+// You may not use that `consumer` anymore out here; it has
+// been destroyed. But you can use `xSquared`.
+console.log(xSquared);
+```
+
+#### SourceMapConsumer.prototype.destroy()
+
+Free this source map consumer's associated wasm data that is manually-managed.
+
+```js
+consumer.destroy();
+```
+
+Alternatively, you can use `SourceMapConsumer.with` to avoid needing to remember
+to call `destroy`.
+
+#### SourceMapConsumer.prototype.computeColumnSpans()
+
+Compute the last column for each generated mapping. The last column is
+inclusive.
+
+```js
+// Before:
+consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1 },
+//   { line: 2,
+//     column: 10 },
+//   { line: 2,
+//     column: 20 } ]
+
+consumer.computeColumnSpans();
+
+// After:
+consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1,
+//     lastColumn: 9 },
+//   { line: 2,
+//     column: 10,
+//     lastColumn: 19 },
+//   { line: 2,
+//     column: 20,
+//     lastColumn: Infinity } ]
+```
+
+#### 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.  Line numbers in
+  this library are 1-based (note that the underlying source map
+  specification uses 0-based line numbers -- this library handles the
+  translation).
+
+* `column`: The column number in the generated source.  Column numbers
+  in this library are 0-based.
+
+* `bias`: Either `SourceMapConsumer.GREATEST_LOWER_BOUND` or
+  `SourceMapConsumer.LEAST_UPPER_BOUND`. Specifies whether to return the closest
+  element that is smaller than or greater than the one we are searching for,
+  respectively, if the exact element cannot be found.  Defaults to
+  `SourceMapConsumer.GREATEST_LOWER_BOUND`.
+
+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.  The line number is 1-based.
+
+* `column`: The column number in the original source, or null if this
+  information is not available.  The column number is 0-based.
+
+* `name`: The original identifier, or null if this information is not available.
+
+```js
+consumer.originalPositionFor({ line: 2, column: 10 })
+// { source: 'foo.coffee',
+//   line: 2,
+//   column: 2,
+//   name: null }
+
+consumer.originalPositionFor({ line: 99999999999999999, column: 999999999999999 })
+// { source: null,
+//   line: null,
+//   column: null,
+//   name: null }
+```
+
+#### 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.  The line number is
+  1-based.
+
+* `column`: The column number in the original source.  The column
+  number is 0-based.
+
+and an object is returned with the following properties:
+
+* `line`: The line number in the generated source, or null.  The line
+  number is 1-based.
+
+* `column`: The column number in the generated source, or null.  The
+  column number is 0-based.
+
+```js
+consumer.generatedPositionFor({ source: "example.js", line: 2, column: 10 })
+// { line: 1,
+//   column: 56 }
+```
+
+#### SourceMapConsumer.prototype.allGeneratedPositionsFor(originalPosition)
+
+Returns all generated line and column information for the original source, line,
+and column provided. If no column is provided, returns all mappings
+corresponding to a either the line we are searching for or the next closest line
+that has any mappings. Otherwise, returns all mappings corresponding to the
+given line and either the column we are searching for or the next closest column
+that has any offsets.
+
+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.  The line number is
+  1-based.
+
+* `column`: Optional. The column number in the original source.  The
+  column number is 0-based.
+
+and an array of objects is returned, each with the following properties:
+
+* `line`: The line number in the generated source, or null.  The line
+  number is 1-based.
+
+* `column`: The column number in the generated source, or null.  The
+  column number is 0-based.
+
+```js
+consumer.allGeneratedpositionsfor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1 },
+//   { line: 2,
+//     column: 10 },
+//   { line: 2,
+//     column: 20 } ]
+```
+
+#### SourceMapConsumer.prototype.hasContentsOfAllSources()
+
+Return true if we have the embedded source content for every source listed in
+the source map, false otherwise.
+
+In other words, if this method returns `true`, then
+`consumer.sourceContentFor(s)` will succeed for every source `s` in
+`consumer.sources`.
+
+```js
+// ...
+if (consumer.hasContentsOfAllSources()) {
+  consumerReadyCallback(consumer);
+} else {
+  fetchSources(consumer, consumerReadyCallback);
+}
+// ...
+```
+
+#### SourceMapConsumer.prototype.sourceContentFor(source[, returnNullOnMissing])
+
+Returns the original source content for the source provided. The only
+argument is the URL of the original source file.
+
+If the source content for the given source is not found, then an error is
+thrown. Optionally, pass `true` as the second param to have `null` returned
+instead.
+
+```js
+consumer.sources
+// [ "my-cool-lib.clj" ]
+
+consumer.sourceContentFor("my-cool-lib.clj")
+// "..."
+
+consumer.sourceContentFor("this is not in the source map");
+// Error: "this is not in the source map" is not in the source map
+
+consumer.sourceContentFor("this is not in the source map", true);
+// null
+```
+
+#### 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`.
+
+```js
+consumer.eachMapping(function (m) { console.log(m); })
+// ...
+// { source: 'illmatic.js',
+//   generatedLine: 1,
+//   generatedColumn: 0,
+//   originalLine: 1,
+//   originalColumn: 0,
+//   name: null }
+// { source: 'illmatic.js',
+//   generatedLine: 2,
+//   generatedColumn: 0,
+//   originalLine: 2,
+//   originalColumn: 0,
+//   name: null }
+// ...
+```
+### 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.
+
+```js
+var generator = new sourceMap.SourceMapGenerator({
+  file: "my-generated-javascript-file.js",
+  sourceRoot: "http://example.com/app/js/"
+});
+```
+
+#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
+
+Creates a new `SourceMapGenerator` from an existing `SourceMapConsumer` instance.
+
+* `sourceMapConsumer` The SourceMap.
+
+```js
+var generator = sourceMap.SourceMapGenerator.fromSourceMap(consumer);
+```
+
+#### 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.
+
+```js
+generator.addMapping({
+  source: "module-one.scm",
+  original: { line: 128, column: 0 },
+  generated: { line: 3, column: 456 }
+})
+```
+
+#### 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.
+
+```js
+generator.setSourceContent("module-one.scm",
+                           fs.readFileSync("path/to/module-one.scm"))
+```
+
+#### 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 minimum 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.
+
+```js
+generator.toString()
+// '{"version":3,"sources":["module-one.scm"],"names":[],"mappings":"...snip...","file":"my-generated-javascript-file.js","sourceRoot":"http://example.com/app/js/"}'
+```
+
+### 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.  The line number is 1-based.
+
+* `column`: The original column number associated with this source node, or null
+  if it isn't associated with an original column.  The column number
+  is 0-based.
+
+* `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.
+
+```js
+var node = new SourceNode(1, 2, "a.cpp", [
+  new SourceNode(3, 4, "b.cpp", "extern int status;\n"),
+  new SourceNode(5, 6, "c.cpp", "std::string* make_string(size_t n);\n"),
+  new SourceNode(7, 8, "d.cpp", "int main(int argc, char** argv) {}\n"),
+]);
+```
+
+#### 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.
+
+```js
+const consumer = await new SourceMapConsumer(fs.readFileSync("path/to/my-file.js.map", "utf8"));
+const node = SourceNode.fromStringWithSourceMap(fs.readFileSync("path/to/my-file.js"), consumer);
+```
+
+#### 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.
+
+```js
+node.add(" + ");
+node.add(otherNode);
+node.add([leftHandOperandNode, " + ", rightHandOperandNode]);
+```
+
+#### 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.
+
+```js
+node.prepend("/** Build Id: f783haef86324gf **/\n\n");
+```
+
+#### 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
+
+```js
+node.setSourceContent("module-one.scm",
+                      fs.readFileSync("path/to/module-one.scm"))
+```
+
+#### 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.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.walk(function (code, loc) { console.log("WALK:", code, loc); })
+// WALK: uno { source: 'b.js', line: 3, column: 4, name: null }
+// WALK: dos { source: 'a.js', line: 1, column: 2, name: null }
+// WALK: tres { source: 'a.js', line: 1, column: 2, name: null }
+// WALK: quatro { source: 'c.js', line: 5, column: 6, name: null }
+```
+
+#### 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.
+
+```js
+var a = new SourceNode(1, 2, "a.js", "generated from a");
+a.setSourceContent("a.js", "original a");
+var b = new SourceNode(1, 2, "b.js", "generated from b");
+b.setSourceContent("b.js", "original b");
+var c = new SourceNode(1, 2, "c.js", "generated from c");
+c.setSourceContent("c.js", "original c");
+
+var node = new SourceNode(null, null, null, [a, b, c]);
+node.walkSourceContents(function (source, contents) { console.log("WALK:", source, ":", contents); })
+// WALK: a.js : original a
+// WALK: b.js : original b
+// WALK: c.js : original c
+```
+
+#### 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.
+
+```js
+var lhs = new SourceNode(1, 2, "a.rs", "my_copy");
+var operand = new SourceNode(3, 4, "a.rs", "=");
+var rhs = new SourceNode(5, 6, "a.rs", "orig.clone()");
+
+var node = new SourceNode(null, null, null, [ lhs, operand, rhs ]);
+var joinedNode = node.join(" ");
+```
+
+#### SourceNode.prototype.replaceRight(pattern, replacement)
+
+Call `String.prototype.replace` on the very right-most source snippet. Useful
+for trimming white space from the end of a source node, etc.
+
+* `pattern`: The pattern to replace.
+
+* `replacement`: The thing to replace the pattern with.
+
+```js
+// Trim trailing white space.
+node.replaceRight(/\s*$/, "");
+```
+
+#### 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.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.toString()
+// 'unodostresquatro'
+```
+
+#### 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`.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.toStringWithSourceMap({ file: "my-output-file.js" })
+// { code: 'unodostresquatro',
+//   map: [object SourceMapGenerator] }
+```
