+# @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.

+<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
+

+
+## 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');

+## 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.

+
+```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.
+
+**Params**
+
+* `input` **{String}**: String to test.
+* `glob` **{RegExp|String}**: Glob pattern or regex created by [.makeRe](#makeRe).

+
+**Example**
+
+```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).

+
+**Example**
+
+```js
+const picomatch = require('picomatch');

+
+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**
+
+```js

+Scan a glob pattern to separate the pattern into segments.
+
+**Params**
+
+* `input` **{String}**: Glob pattern to scan.
+* `options` **{Object}**

+  start: 3,
+  base: 'foo',
+  glob: '*.js',
+  isBrace: false,
+  isBracket: false,
+  isGlob: true,
+  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}**

+* `returns` **{RegExp}**: Returns a regex created from the given pattern.
+
+**Example**

+
+## 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`           | `boolean`      | `65536`     | Limit the max length of the input string. An error is thrown if the input string is longer than this value. |
+| `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. |

+
+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
+```
+
+#### 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\\)'));
+```
+
+<br>

+
+## 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.
