+> Wrap words to a specified length.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save word-wrap
+```
+
+## Usage
+
+```js
+var wrap = require('word-wrap');
+
+wrap('Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.');
+```
+
+Results in:
+
+```
+  Lorem ipsum dolor sit amet, consectetur adipiscing
+  elit, sed do eiusmod tempor incididunt ut labore
+  et dolore magna aliqua. Ut enim ad minim veniam,
+  quis nostrud exercitation ullamco laboris nisi ut
+  aliquip ex ea commodo consequat.
+```
+
+## Options

+
+### options.width
+
+Type: `Number`
+
+Default: `50`
+
+The width of the text before wrapping to a new line.
+
+**Example:**
+
+```js
+wrap(str, {width: 60});
+```
+
+### options.indent
+
+Type: `String`
+
+Default: `` (none)
+
+The string to use at the beginning of each line.
+
+**Example:**
+
+```js
+wrap(str, {indent: '      '});
+```
+
+### options.newline
+
+Type: `String`
+
+Default: `\n`
+
+The string to use at the end of each line.
+
+**Example:**
+
+```js
+wrap(str, {newline: '\n\n'});
+```
+
+### options.escape
+
+Type: `function`
+
+Default: `function(str){return str;}`
+
+An escape function to run on each line after splitting them.
+
+**Example:**
+
+```js
+var xmlescape = require('xml-escape');
+wrap(str, {
+  escape: function(string){
+    return xmlescape(string);
+  }
+});
+```
+
+### options.trim
+
+Type: `Boolean`
+
+Default: `false`
+
+Trim trailing whitespace from the returned string. This option is included since `.trim()` would also strip the leading indentation from the first line.
+
+**Example:**
+
+```js
+wrap(str, {trim: true});
+```
+
+### options.cut
+
+Type: `Boolean`
+
+Default: `false`
+
+Break a word between any two letters when the word is longer than the specified width.
+
+**Example:**
+
+```js
+wrap(str, {cut: true});
+```

+
+> Simple [“Least Recently Used” (LRU) cache](https://en.m.wikipedia.org/wiki/Cache_replacement_policies#Least_Recently_Used_.28LRU.29)
+
+Useful when you need to cache something and limit memory usage.
+
+Inspired by the [`hashlru` algorithm](https://github.com/dominictarr/hashlru#algorithm), but instead uses [`Map`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Map) to support keys of any type, not just strings, and values can be `undefined`.
+
+## Install
+
+```
+$ npm install quick-lru
+```
+
+## Usage
+
+```js
+const QuickLRU = require('quick-lru');
+
+const lru = new QuickLRU({maxSize: 1000});
+
+lru.set('🦄', '🌈');
+
+lru.has('🦄');
+//=> true
+
+lru.get('🦄');
+//=> '🌈'
+```
+
+## API
+
+### new QuickLRU(options?)
+
+Returns a new instance.
+
+### options
+
+Type: `object`
+
+#### maxSize
+
+*Required*\
+Type: `number`
+
+The maximum number of items before evicting the least recently used items.
+
+#### maxAge
+
+Type: `number`\
+Default: `Infinity`
+
+The maximum number of milliseconds an item should remain in cache.
+By default maxAge will be Infinity, which means that items will never expire.
+
+Lazy expiration happens upon the next `write` or `read` call.
+
+Individual expiration of an item can be specified by the `set(key, value, options)` method.
+
+#### onEviction
+
+*Optional*\
+Type: `(key, value) => void`
+
+Called right before an item is evicted from the cache.
+
+Useful for side effects or for items like object URLs that need explicit cleanup (`revokeObjectURL`).
+
+### Instance
+
+The instance is [`iterable`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Iteration_protocols) so you can use it directly in a [`for…of`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Statements/for...of) loop.
+
+Both `key` and `value` can be of any type.
+
+#### .set(key, value, options?)
+
+Set an item. Returns the instance.
+
+Individual expiration of an item can be specified with the `maxAge` option. If not specified, the global `maxAge` value will be used in case it is specified on the constructor, otherwise the item will never expire.
+
+#### .get(key)
+
+Get an item.
+
+#### .has(key)
+
+Check if an item exists.
+
+#### .peek(key)
+
+Get an item without marking it as recently used.
+
+#### .delete(key)
+
+Delete an item.
+
+Returns `true` if the item is removed or `false` if the item doesn't exist.
+
+#### .clear()
+
+Delete all items.
+
+#### .resize(maxSize)
+
+Update the `maxSize`, discarding items as necessary. Insertion order is mostly preserved, though this is not a strong guarantee.
+
+Useful for on-the-fly tuning of cache sizes in live systems.
+
+#### .keys()
+
+Iterable for all the keys.
+
+#### .values()
+
+Iterable for all the values.
+
+#### .entriesAscending()
+
+Iterable for all entries, starting with the oldest (ascending in recency).
+
+#### .entriesDescending()
+
+Iterable for all entries, starting with the newest (descending in recency).
+
+#### .size
+
+The stored item count.

+
+> Remap sequential sourcemaps through transformations to point at the original source code
+
+Remapping allows you to take the sourcemaps generated through transforming your code and "remap"
+them to the original source locations. Think "my minified code, transformed with babel and bundled
+with webpack", all pointing to the correct location in your original source code.
+
+With remapping, none of your source code transformations need to be aware of the input's sourcemap,
+they only need to generate an output sourcemap. This greatly simplifies building custom
+transformations (think a find-and-replace).
+
+## Installation
+
+```sh
+npm install @ampproject/remapping
+```
+
+## Usage
+
+```typescript
+function remapping(
+  map: SourceMap | SourceMap[],
+  loader: (file: string, ctx: LoaderContext) => (SourceMap | null | undefined),
+  options?: { excludeContent: boolean, decodedMappings: boolean }
+): SourceMap;
+
+// LoaderContext gives the loader the importing sourcemap, tree depth, the ability to override the
+// "source" location (where child sources are resolved relative to, or the location of original
+// source), and the ability to override the "content" of an original source for inclusion in the
+// output sourcemap.
+type LoaderContext = {
+ readonly importer: string;
+ readonly depth: number;
+ source: string;
+ content: string | null | undefined;
+}
+```
+
+`remapping` takes the final output sourcemap, and a `loader` function. For every source file pointer
+in the sourcemap, the `loader` will be called with the resolved path. If the path itself represents
+a transformed file (it has a sourcmap associated with it), then the `loader` should return that
+sourcemap. If not, the path will be treated as an original, untransformed source code.
+
+```js
+// Babel transformed "helloworld.js" into "transformed.js"
+const transformedMap = JSON.stringify({
+  file: 'transformed.js',
+  // 1st column of 2nd line of output file translates into the 1st source
+  // file, line 3, column 2
+  mappings: ';CAEE',
+  sources: ['helloworld.js'],
+  version: 3,
+});
+
+// Uglify minified "transformed.js" into "transformed.min.js"
+const minifiedTransformedMap = JSON.stringify({
+  file: 'transformed.min.js',
+  // 0th column of 1st line of output file translates into the 1st source
+  // file, line 2, column 1.
+  mappings: 'AACC',
+  names: [],
+  sources: ['transformed.js'],
+  version: 3,
+});
+
+const remapped = remapping(
+  minifiedTransformedMap,
+  (file, ctx) => {
+
+    // The "transformed.js" file is an transformed file.
+    if (file === 'transformed.js') {
+      // The root importer is empty.
+      console.assert(ctx.importer === '');
+      // The depth in the sourcemap tree we're currently loading.
+      // The root `minifiedTransformedMap` is depth 0, and its source children are depth 1, etc.
+      console.assert(ctx.depth === 1);
+
+      return transformedMap;
+    }
+
+    // Loader will be called to load transformedMap's source file pointers as well.
+    console.assert(file === 'helloworld.js');
+    // `transformed.js`'s sourcemap points into `helloworld.js`.
+    console.assert(ctx.importer === 'transformed.js');
+    // This is a source child of `transformed`, which is a source child of `minifiedTransformedMap`.
+    console.assert(ctx.depth === 2);
+    return null;
+  }
+);
+
+console.log(remapped);
+// {
+//   file: 'transpiled.min.js',
+//   mappings: 'AAEE',
+//   sources: ['helloworld.js'],
+//   version: 3,
+// };
+```
+
+In this example, `loader` will be called twice:
+
+1. `"transformed.js"`, the first source file pointer in the `minifiedTransformedMap`. We return the
+   associated sourcemap for it (its a transformed file, after all) so that sourcemap locations can
+   be traced through it into the source files it represents.
+2. `"helloworld.js"`, our original, unmodified source code. This file does not have a sourcemap, so
+   we return `null`.
+
+The `remapped` sourcemap now points from `transformed.min.js` into locations in `helloworld.js`. If
+you were to read the `mappings`, it says "0th column of the first line output line points to the 1st
+column of the 2nd line of the file `helloworld.js`".
+
+### Multiple transformations of a file
+
+As a convenience, if you have multiple single-source transformations of a file, you may pass an
+array of sourcemap files in the order of most-recent transformation sourcemap first. Note that this
+changes the `importer` and `depth` of each call to our loader. So our above example could have been
+written as:
+
+```js
+const remapped = remapping(
+  [minifiedTransformedMap, transformedMap],
+  () => null
+);
+
+console.log(remapped);
+// {
+//   file: 'transpiled.min.js',
+//   mappings: 'AAEE',
+//   sources: ['helloworld.js'],
+//   version: 3,
+// };
+```
+
+### Advanced control of the loading graph
+
+#### `source`
+
+The `source` property can overridden to any value to change the location of the current load. Eg,
+for an original source file, it allows us to change the location to the original source regardless
+of what the sourcemap source entry says. And for transformed files, it allows us to change the
+relative resolving location for child sources of the loaded sourcemap.
+
+```js
+const remapped = remapping(
+  minifiedTransformedMap,
+  (file, ctx) => {
+
+    if (file === 'transformed.js') {
+      // We pretend the transformed.js file actually exists in the 'src/' directory. When the nested
+      // source files are loaded, they will now be relative to `src/`.
+      ctx.source = 'src/transformed.js';
+      return transformedMap;
+    }
+
+    console.assert(file === 'src/helloworld.js');
+    // We could futher change the source of this original file, eg, to be inside a nested directory
+    // itself. This will be reflected in the remapped sourcemap.
+    ctx.source = 'src/nested/transformed.js';
+    return null;
+  }
+);
+
+console.log(remapped);
+// {
+//   …,
+//   sources: ['src/nested/helloworld.js'],
+// };
+```
+
+
+#### `content`
+
+The `content` property can be overridden when we encounter an original source file. Eg, this allows
+you to manually provide the source content of the original file regardless of whether the
+`sourcesContent` field is present in the parent sourcemap. It can also be set to `null` to remove
+the source content.
+
+```js
+const remapped = remapping(
+  minifiedTransformedMap,
+  (file, ctx) => {
+
+    if (file === 'transformed.js') {
+      // transformedMap does not include a `sourcesContent` field, so usually the remapped sourcemap
+      // would not include any `sourcesContent` values.
+      return transformedMap;
+    }
+
+    console.assert(file === 'helloworld.js');
+    // We can read the file to provide the source content.
+    ctx.content = fs.readFileSync(file, 'utf8');
+    return null;
+  }
+);
+
+console.log(remapped);
+// {
+//   …,
+//   sourcesContent: [
+//     'console.log("Hello world!")',
+//   ],
+// };
+```
+
+### Options
+
+#### excludeContent
+
+By default, `excludeContent` is `false`. Passing `{ excludeContent: true }` will exclude the
+`sourcesContent` field from the returned sourcemap. This is mainly useful when you want to reduce
+the size out the sourcemap.
+
+#### decodedMappings
+
+By default, `decodedMappings` is `false`. Passing `{ decodedMappings: true }` will leave the
+`mappings` field in a [decoded state](https://github.com/rich-harris/sourcemap-codec) instead of
+encoding into a VLQ string.

+## 🏁 Goal
+
+This package provides utility functions and classes for make ESLint custom rules.
+
+For examples:
+
+-   [`getStaticValue`](https://eslint-community.github.io/eslint-utils/api/ast-utils.html#getstaticvalue) evaluates static value on AST.
+-   [`ReferenceTracker`](https://eslint-community.github.io/eslint-utils/api/scope-utils.html#referencetracker-class) checks the members of modules/globals as handling assignments and destructuring.
+
+## 📖 Usage
+
+See [documentation](https://eslint-community.github.io/eslint-utils).
+
+## 📰 Changelog
+
+See [releases](https://github.com/eslint-community/eslint-utils/releases).
+
+## ❤️ Contributing
+
+Welcome contributing!
+
+Please use GitHub's Issues/PRs.
+
+### Development Tools
+
+-   `npm test` runs tests and measures coverage.
+-   `npm run clean` removes the coverage result of `npm test` command.
+-   `npm run coverage` shows the coverage result of the last `npm test` command.
+-   `npm run lint` runs ESLint.
+-   `npm run watch` runs tests on each file change.

+# ESLintRC Library
+
+This repository contains the legacy ESLintRC configuration file format for ESLint. This package is not intended for use outside of the ESLint ecosystem. It is ESLint-specific and not intended for use in other programs.
+
+**Note:** This package is frozen except for critical bug fixes as ESLint moves to a new config system.
+
+## Installation
+
+You can install the package as follows:
+
+```
+npm install @eslint/eslintrc --save-dev
+
+# or
+
+yarn add @eslint/eslintrc -D
+```
+
+## Usage (ESM)
+
+The primary class in this package is `FlatCompat`, which is a utility to translate ESLintRC-style configs into flat configs. Here's how you use it inside of your `eslint.config.js` file:
+
+```js
+import { FlatCompat } from "@eslint/eslintrc";
+import js from "@eslint/js";
+import path from "path";
+import { fileURLToPath } from "url";
+
+// mimic CommonJS variables -- not needed if using CommonJS
+const __filename = fileURLToPath(import.meta.url);
+const __dirname = path.dirname(__filename);
+
+const compat = new FlatCompat({
+    baseDirectory: __dirname,                  // optional; default: process.cwd()
+    resolvePluginsRelativeTo: __dirname,       // optional
+    recommendedConfig: js.configs.recommended, // optional
+    allConfig: js.configs.all,                 // optional
+});
+
+export default [
+
+    // mimic ESLintRC-style extends
+    ...compat.extends("standard", "example"),
+
+    // mimic environments
+    ...compat.env({
+        es2020: true,
+        node: true
+    }),
+
+    // mimic plugins
+    ...compat.plugins("airbnb", "react"),
+
+    // translate an entire config
+    ...compat.config({
+        plugins: ["airbnb", "react"],
+        extends: "standard",
+        env: {
+            es2020: true,
+            node: true
+        },
+        rules: {
+            semi: "error"
+        }
+    })
+];
+```
+
+## Usage (CommonJS)
+
+Using `FlatCompat` in CommonJS files is similar to ESM, but you'll use `require()` and `module.exports` instead of `import` and `export`. Here's how you use it inside of your `eslint.config.js` CommonJS file:
+
+```js
+const { FlatCompat } = require("@eslint/eslintrc");
+const js = require("@eslint/js");
+
+const compat = new FlatCompat({
+    baseDirectory: __dirname,                  // optional; default: process.cwd()
+    resolvePluginsRelativeTo: __dirname,       // optional
+    recommendedConfig: js.configs.recommended, // optional
+    allConfig: js.configs.all,                 // optional
+});
+
+module.exports = [
+
+    // mimic ESLintRC-style extends
+    ...compat.extends("standard", "example"),
+
+    // mimic environments
+    ...compat.env({
+        es2020: true,
+        node: true
+    }),
+
+    // mimic plugins
+    ...compat.plugins("airbnb", "react"),
+
+    // translate an entire config
+    ...compat.config({
+        plugins: ["airbnb", "react"],
+        extends: "standard",
+        env: {
+            es2020: true,
+            node: true
+        },
+        rules: {
+            semi: "error"
+        }
+    })
+];
+```

+ *      Extract the final configuration for a given file. This means merging
