+
+The ESLint custom parser for `.vue` files.
+
+## ⤴️ Motivation
+
+This parser allows us to lint the `<template>` of `.vue` files. We can make mistakes easily on `<template>` if we use complex directives and expressions in the template. This parser and the rules of [eslint-plugin-vue](https://github.com/vuejs/eslint-plugin-vue) would catch some of the mistakes.
+
+## 💿 Installation
+
+```bash
+npm install --save-dev eslint vue-eslint-parser
+```
+
+- Requires Node.js ^12.22.0, ^14.17.0, 16.0.0 or later.
+- Requires ESLint 6.0.0 or later.
+
+## 📖 Usage
+
+1. Write `parser` option into your `.eslintrc.*` file.
+2. Use glob patterns or `--ext .vue` CLI option.
+
+```json
+{
+    "extends": "eslint:recommended",
+    "parser": "vue-eslint-parser"
+}
+```
+
+```console
+$ eslint "src/**/*.{js,vue}"
+# or
+$ eslint src --ext .vue
+```
+
+## 🔧 Options
+
+`parserOptions` has the same properties as what [espree](https://github.com/eslint/espree#usage), the default parser of ESLint, is supporting.
+For example:
+
+```json
+{
+    "parser": "vue-eslint-parser",
+    "parserOptions": {
+        "sourceType": "module",
+        "ecmaVersion": 2018,
+        "ecmaFeatures": {
+            "globalReturn": false,
+            "impliedStrict": false,
+            "jsx": false
+        }
+    }
+}
+```
+
+### parserOptions.parser
+
+You can use `parserOptions.parser` property to specify a custom parser to parse `<script>` tags.
+Other properties than parser would be given to the specified parser.
+For example:
+
+```json
+{
+    "parser": "vue-eslint-parser",
+    "parserOptions": {
+        "parser": "@babel/eslint-parser",
+        "sourceType": "module"
+    }
+}
+```
+
+```json
+{
+    "parser": "vue-eslint-parser",
+    "parserOptions": {
+        "parser": "@typescript-eslint/parser",
+        "sourceType": "module"
+    }
+}
+```
+
+You can also specify an object and change the parser separately for `<script lang="...">`.
+
+```jsonc
+{
+    "parser": "vue-eslint-parser",
+    "parserOptions": {
+        "parser": {
+             // Script parser for `<script>`
+            "js": "espree",
+
+             // Script parser for `<script lang="ts">`
+            "ts": "@typescript-eslint/parser",
+
+             // Script parser for vue directives (e.g. `v-if=` or `:attribute=`)
+             // and vue interpolations (e.g. `{{variable}}`).
+             // If not specified, the parser determined by `<script lang ="...">` is used.
+            "<template>": "espree",
+        }
+    }
+}
+```
+
+If the `parserOptions.parser` is `false`, the `vue-eslint-parser` skips parsing `<script>` tags completely.
+This is useful for people who use the language ESLint community doesn't provide custom parser implementation.
+
+### parserOptions.vueFeatures
+
+You can use `parserOptions.vueFeatures` property to specify how to parse related to Vue features.
+For example:
+
+```json
+{
+    "parser": "vue-eslint-parser",
+    "parserOptions": {
+        "vueFeatures": {
+            "filter": true,
+            "interpolationAsNonHTML": true,
+            "styleCSSVariableInjection": true,
+        }
+    }
+}
+```
+
+### parserOptions.vueFeatures.filter
+
+You can use `parserOptions.vueFeatures.filter` property to specify whether to parse the Vue2 filter. If you specify `false`, the parser does not parse `|` as a filter.
+For example:
+
+```json
+{
+    "parser": "vue-eslint-parser",
+    "parserOptions": {
+        "vueFeatures": {
+            "filter": false
+        }
+    }
+}
+```
+
+If you specify `false`, it can be parsed in the same way as Vue 3.
+The following template parses as a bitwise operation.
+
+```vue
+<template>
+  <div>{{ a | b }}</div>
+</template>
+```
+
+However, the following template that are valid in Vue 2 cannot be parsed.
+
+```vue
+<template>
+  <div>{{ a | valid:filter }}</div>
+</template>
+```
+
+### parserOptions.vueFeatures.interpolationAsNonHTML
+
+You can use `parserOptions.vueFeatures.interpolationAsNonHTML` property to specify whether to parse the interpolation as HTML. If you specify `true`, the parser handles the interpolation as non-HTML (However, you can use HTML escaping in the interpolation). Default is `true`.
+For example:
+
+```json
+{
+    "parser": "vue-eslint-parser",
+    "parserOptions": {
+        "vueFeatures": {
+            "interpolationAsNonHTML": true
+        }
+    }
+}
+```
+
+If you specify `true`, it can be parsed in the same way as Vue 3.
+The following template can be parsed well.
+
+```vue
+<template>
+  <div>{{a<b}}</div>
+</template>
+```
+
+But, it cannot be parsed with Vue 2.
+
+### parserOptions.vueFeatures.styleCSSVariableInjection
+
+If set to `true`, to parse expressions in `v-bind` CSS functions inside `<style>` tags. `v-bind()` is parsed into the `VExpressionContainer` AST node and held in the `VElement` of `<style>`. Default is `true`.
+
+See also to [here](https://github.com/vuejs/rfcs/blob/master/active-rfcs/0043-sfc-style-variables.md).
+
+## 🎇 Usage for custom rules / plugins
+
+- This parser provides `parserServices` to traverse `<template>`.
+    - `defineTemplateBodyVisitor(templateVisitor, scriptVisitor, options)` ... returns ESLint visitor to traverse `<template>`.
+    - `getTemplateBodyTokenStore()` ... returns ESLint `TokenStore` to get the tokens of `<template>`.
+    - `getDocumentFragment()` ... returns the root `VDocumentFragment`.
+    - `defineCustomBlocksVisitor(context, customParser, rule, scriptVisitor)` ... returns ESLint visitor that parses and traverses the contents of the custom block.
+    - `defineDocumentVisitor(documentVisitor, options)` ... returns ESLint visitor to traverses the document.
+- [ast.md](./docs/ast.md) is `<template>` AST specification.
+- [mustache-interpolation-spacing.js](https://github.com/vuejs/eslint-plugin-vue/blob/b434ff99d37f35570fa351681e43ba2cf5746db3/lib/rules/mustache-interpolation-spacing.js) is an example.
+
+### `defineTemplateBodyVisitor(templateBodyVisitor, scriptVisitor, options)`
+
+*Arguments*
+
+- `templateBodyVisitor` ... Event handlers for `<template>`.
+- `scriptVisitor` ... Event handlers for `<script>` or scripts. (optional)
+- `options` ... Options. (optional)
+  - `templateBodyTriggerSelector` ... Script AST node selector that triggers the templateBodyVisitor. Default is `"Program:exit"`. (optional)
+
+```ts
+import { AST } from "vue-eslint-parser"
+
+export function create(context) {
+    return context.parserServices.defineTemplateBodyVisitor(
+        // Event handlers for <template>.
+        {
+            VElement(node: AST.VElement): void {
+                //...
+            }
+        },
+        // Event handlers for <script> or scripts. (optional)
+        {
+            Program(node: AST.ESLintProgram): void {
+                //...
+            }
+        },
+        // Options. (optional)
+        {
+            templateBodyTriggerSelector: "Program:exit"
+        }
+    )
+}
+```
+
+## ⚠️ Known Limitations
+
+Some rules make warnings due to the outside of `<script>` tags.
+Please disable those rules for `.vue` files as necessary.
+
+- [eol-last](http://eslint.org/docs/rules/eol-last)
+- [linebreak-style](http://eslint.org/docs/rules/linebreak-style)
+- [max-len](http://eslint.org/docs/rules/max-len)
+- [max-lines](http://eslint.org/docs/rules/max-lines)
+- [no-trailing-spaces](http://eslint.org/docs/rules/no-trailing-spaces)
+- [unicode-bom](http://eslint.org/docs/rules/unicode-bom)
+- Other rules which are using the source code text instead of AST might be confused as well.

+# ESLint Scope
+
+ESLint Scope is the [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm) scope analyzer used in ESLint. It is a fork of [escope](http://github.com/estools/escope).
+
+## Install
+
+```
+npm i eslint-scope --save
+```
+
+## 📖 Usage
+
+To use in an ESM file:
+
+```js
+import * as eslintScope from 'eslint-scope';
+```
+
+To use in a CommonJS file:
+
+```js
+const eslintScope = require('eslint-scope');
+```
+
+Example:
+
+```js
+import * as eslintScope from 'eslint-scope';
+import * as espree from 'espree';
+import estraverse from 'estraverse';
+
+const ast = espree.parse(code, { range: true });
+const scopeManager = eslintScope.analyze(ast);
+
+const currentScope = scopeManager.acquire(ast);   // global scope
+
+estraverse.traverse(ast, {
+    enter (node, parent) {
+        // do stuff
+
+        if (/Function/.test(node.type)) {
+            currentScope = scopeManager.acquire(node);  // get current function scope
+        }
+    },
+    leave(node, parent) {
+        if (/Function/.test(node.type)) {
+            currentScope = currentScope.upper;  // set to parent scope
+        }
+
+        // do stuff
+    }
+});
+```

+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# eslint-visitor-keys
+
+[![npm version](https://img.shields.io/npm/v/eslint-visitor-keys.svg)](https://www.npmjs.com/package/eslint-visitor-keys)
+[![Downloads/month](https://img.shields.io/npm/dm/eslint-visitor-keys.svg)](http://www.npmtrends.com/eslint-visitor-keys)
+[![Build Status](https://github.com/eslint/eslint-visitor-keys/workflows/CI/badge.svg)](https://github.com/eslint/eslint-visitor-keys/actions)
+
+Constants and utilities about visitor keys to traverse AST.
+
+## 💿 Installation
+
+Use [npm] to install.
+
+```bash
+$ npm install eslint-visitor-keys
+```
+
+### Requirements
+
+- [Node.js] `^12.22.0`, `^14.17.0`, or `>=16.0.0`
+
+
+## 📖 Usage
+
+To use in an ESM file:
+
+```js
+import * as evk from "eslint-visitor-keys"
+```
+
+To use in a CommonJS file:
+
+```js
+const evk = require("eslint-visitor-keys")
+```
+
+### evk.KEYS
+
+> type: `{ [type: string]: string[] | undefined }`
+
+Visitor keys. This keys are frozen.
+
+This is an object. Keys are the type of [ESTree] nodes. Their values are an array of property names which have child nodes.
+
+For example:
+
+```
+console.log(evk.KEYS.AssignmentExpression) // → ["left", "right"]
+```
+
+### evk.getKeys(node)
+
+> type: `(node: object) => string[]`
+
+Get the visitor keys of a given AST node.
+
+This is similar to `Object.keys(node)` of ES Standard, but some keys are excluded: `parent`, `leadingComments`, `trailingComments`, and names which start with `_`.
+
+This will be used to traverse unknown nodes.
+
+For example:
+
+```js
+const node = {
+    type: "AssignmentExpression",
+    left: { type: "Identifier", name: "foo" },
+    right: { type: "Literal", value: 0 }
+}
+console.log(evk.getKeys(node)) // → ["type", "left", "right"]
+```
+
+### evk.unionWith(additionalKeys)
+
+> type: `(additionalKeys: object) => { [type: string]: string[] | undefined }`
+
+Make the union set with `evk.KEYS` and the given keys.
+
+- The order of keys is, `additionalKeys` is at first, then `evk.KEYS` is concatenated after that.
+- It removes duplicated keys as keeping the first one.
+
+For example:
+
+```js
+console.log(evk.unionWith({
+    MethodDefinition: ["decorators"]
+})) // → { ..., MethodDefinition: ["decorators", "key", "value"], ... }
+```
+
+## 📰 Change log
+
+See [GitHub releases](https://github.com/eslint/eslint-visitor-keys/releases).
+
+## 🍻 Contributing
+
+Welcome. See [ESLint contribution guidelines](https://eslint.org/docs/developer-guide/contributing/).
+
+### Development commands
+
+- `npm test` runs tests and measures code coverage.
+- `npm run lint` checks source codes with ESLint.
+- `npm run coverage` opens the code coverage report of the previous test with your default browser.

+# Espree
+
+Espree started out as a fork of [Esprima](http://esprima.org) v1.2.2, the last stable published released of Esprima before work on ECMAScript 6 began. Espree is now built on top of [Acorn](https://github.com/ternjs/acorn), which has a modular architecture that allows extension of core functionality. The goal of Espree is to produce output that is similar to Esprima with a similar API so that it can be used in place of Esprima.
+
+## Usage
+
+Install:
+
+```
+npm i espree
+```
+
+To use in an ESM file:
+
+```js
+import * as espree from "espree";
+
+const ast = espree.parse(code);
+```
+
+To use in a Common JS file:
+
+```js
+const espree = require("espree");
+
+const ast = espree.parse(code);
+```
+
+## API
+
+### `parse()`
+
+`parse` parses the given code and returns a abstract syntax tree (AST). It takes two parameters.
+
+- `code` [string]() - the code which needs to be parsed.
+- `options (Optional)` [Object]() - read more about this [here](#options).
+
+```js
+import * as espree from "espree";
+
+const ast = espree.parse(code);
+```
+
+**Example :**
+
+```js
+const ast = espree.parse('let foo = "bar"', { ecmaVersion: 6 });
+console.log(ast);
+```
+
+<details><summary>Output</summary>
+<p>
+
+```
+Node {
+  type: 'Program',
+  start: 0,
+  end: 15,
+  body: [
+    Node {
+      type: 'VariableDeclaration',
+      start: 0,
+      end: 15,
+      declarations: [Array],
+      kind: 'let'
+    }
+  ],
+  sourceType: 'script'
+}
+```
+
+</p>
+</details>
+
+### `tokenize()`
+
+`tokenize` returns the tokens of a given code. It takes two parameters.
+
+- `code` [string]() - the code which needs to be parsed.
+- `options (Optional)` [Object]() - read more about this [here](#options).
+
+Even if `options` is empty or undefined or `options.tokens` is `false`, it assigns it to `true` in order to get the `tokens` array
+
+**Example :**
+
+```js
+import * as espree from "espree";
+
+const tokens = espree.tokenize('let foo = "bar"', { ecmaVersion: 6 });
+console.log(tokens);
+```
+
+<details><summary>Output</summary>
+<p>
+
+```
+Token { type: 'Keyword', value: 'let', start: 0, end: 3 },
+Token { type: 'Identifier', value: 'foo', start: 4, end: 7 },
+Token { type: 'Punctuator', value: '=', start: 8, end: 9 },
+Token { type: 'String', value: '"bar"', start: 10, end: 15 }
+```
+
+</p>
+</details>
+
+### `version`
+
+Returns the current `espree` version
+
+### `VisitorKeys`
+
+Returns all visitor keys for traversing the AST from [eslint-visitor-keys](https://github.com/eslint/eslint-visitor-keys)
+
+### `latestEcmaVersion`
+
+Returns the latest ECMAScript supported by `espree`
+
+### `supportedEcmaVersions`
+
+Returns an array of all supported ECMAScript versions
+
+## Options
+
+```js
+const options = {
+    // attach range information to each node
+    range: false,
+
+    // attach line/column location information to each node
+    loc: false,
+
+    // create a top-level comments array containing all comments
+    comment: false,
+
+    // create a top-level tokens array containing all tokens
+    tokens: false,
+
+    // Set to 3, 5 (the default), 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15 to specify the version of ECMAScript syntax you want to use.
+    // You can also set to 2015 (same as 6), 2016 (same as 7), 2017 (same as 8), 2018 (same as 9), 2019 (same as 10), 2020 (same as 11), 2021 (same as 12), 2022 (same as 13), 2023 (same as 14) or 2024 (same as 15) to use the year-based naming.
+    // You can also set "latest" to use the most recently supported version.
+    ecmaVersion: 3,
+
+    allowReserved: true, // only allowed when ecmaVersion is 3
+
+    // specify which type of script you're parsing ("script", "module", or "commonjs")
+    sourceType: "script",
+
+    // specify additional language features
+    ecmaFeatures: {
+
+        // enable JSX parsing
+        jsx: false,
+
+        // enable return in global scope (set to true automatically when sourceType is "commonjs")
+        globalReturn: false,
+
+        // enable implied strict mode (if ecmaVersion >= 5)
+        impliedStrict: false
+    }
+}
+```
+
+## Esprima Compatibility Going Forward
+
+The primary goal is to produce the exact same AST structure and tokens as Esprima, and that takes precedence over anything else. (The AST structure being the [ESTree](https://github.com/estree/estree) API with JSX extensions.) Separate from that, Espree may deviate from what Esprima outputs in terms of where and how comments are attached, as well as what additional information is available on AST nodes. That is to say, Espree may add more things to the AST nodes than Esprima does but the overall AST structure produced will be the same.
+
+Espree may also deviate from Esprima in the interface it exposes.
+

+
+## Security Policy
+
+We work hard to ensure that Espree is safe for everyone and that security issues are addressed quickly and responsibly. Read the full [security policy](https://github.com/eslint/.github/blob/master/SECURITY.md).
+
+## Build Commands
+
+* `npm test` - run all linting and tests
+* `npm run lint` - run all linting
+
+## Differences from Espree 2.x
+
+* The `tokenize()` method does not use `ecmaFeatures`. Any string will be tokenized completely based on ECMAScript 6 semantics.
+* Trailing whitespace no longer is counted as part of a node.
+* `let` and `const` declarations are no longer parsed by default. You must opt-in by using an `ecmaVersion` newer than `5` or setting `sourceType` to `module`.
+* The `esparse` and `esvalidate` binary scripts have been removed.
+* There is no `tolerant` option. We will investigate adding this back in the future.
+
+## Known Incompatibilities
+
+In an effort to help those wanting to transition from other parsers to Espree, the following is a list of noteworthy incompatibilities with other parsers. These are known differences that we do not intend to change.
+
+### Esprima 1.2.2
+
+* Esprima counts trailing whitespace as part of each AST node while Espree does not. In Espree, the end of a node is where the last token occurs.
+* Espree does not parse `let` and `const` declarations by default.
+* Error messages returned for parsing errors are different.
+* There are two addition properties on every node and token: `start` and `end`. These represent the same data as `range` and are used internally by Acorn.
+
+### Esprima 2.x
+
+* Esprima 2.x uses a different comment attachment algorithm that results in some comments being added in different places than Espree. The algorithm Espree uses is the same one used in Esprima 1.2.2.
+
+## Frequently Asked Questions
+
+### Why another parser
+
+[ESLint](http://eslint.org) had been relying on Esprima as its parser from the beginning. While that was fine when the JavaScript language was evolving slowly, the pace of development increased dramatically and Esprima had fallen behind. ESLint, like many other tools reliant on Esprima, has been stuck in using new JavaScript language features until Esprima updates, and that caused our users frustration.
+
+We decided the only way for us to move forward was to create our own parser, bringing us inline with JSHint and JSLint, and allowing us to keep implementing new features as we need them. We chose to fork Esprima instead of starting from scratch in order to move as quickly as possible with a compatible API.
+
+With Espree 2.0.0, we are no longer a fork of Esprima but rather a translation layer between Acorn and Esprima syntax. This allows us to put work back into a community-supported parser (Acorn) that is continuing to grow and evolve while maintaining an Esprima-compatible parser for those utilities still built on Esprima.
+
+### Have you tried working with Esprima?
+
+Yes. Since the start of ESLint, we've regularly filed bugs and feature requests with Esprima and will continue to do so. However, there are some different philosophies around how the projects work that need to be worked through. The initial goal was to have Espree track Esprima and eventually merge the two back together, but we ultimately decided that building on top of Acorn was a better choice due to Acorn's plugin support.
+
+### Why don't you just use Acorn?
+
+Acorn is a great JavaScript parser that produces an AST that is compatible with Esprima. Unfortunately, ESLint relies on more than just the AST to do its job. It relies on Esprima's tokens and comment attachment features to get a complete picture of the source code. We investigated switching to Acorn, but the inconsistencies between Esprima and Acorn created too much work for a project like ESLint.
+
+We are building on top of Acorn, however, so that we can contribute back and help make Acorn even better.
+
+### What ECMAScript features do you support?
+
+Espree supports all ECMAScript 2023 features and partially supports ECMAScript 2024 features.
+
+Because ECMAScript 2024 is still under development, we are implementing features as they are finalized. Currently, Espree supports:
+
+* [RegExp v flag with set notation + properties of strings](https://github.com/tc39/proposal-regexp-v-flag)
+
+See [finished-proposals.md](https://github.com/tc39/proposals/blob/master/finished-proposals.md) to know what features are finalized.
+
+### How do you determine which experimental features to support?
+
+In general, we do not support experimental JavaScript features. We may make exceptions from time to time depending on the maturity of the features.

+### Estraverse [![Build Status](https://secure.travis-ci.org/estools/estraverse.svg)](http://travis-ci.org/estools/estraverse)
+
+Estraverse ([estraverse](http://github.com/estools/estraverse)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+traversal functions from [esmangle project](http://github.com/estools/esmangle).
+
+### Documentation
+
+You can find usage docs at [wiki page](https://github.com/estools/estraverse/wiki/Usage).
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node, parent) {
+        if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
+            return estraverse.VisitorOption.Skip;
+    },
+    leave: function (node, parent) {
+        if (node.type == 'VariableDeclarator')
+          console.log(node.id.name);
+    }
+});
+```
+
+We can use `this.skip`, `this.remove` and `this.break` functions instead of using Skip, Remove and Break.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node) {
+        this.break();
+    }
+});
+```
+
+And estraverse provides `estraverse.replace` function. When returning node from `enter`/`leave`, current node is replaced with it.
+
+```javascript
+result = estraverse.replace(tree, {
+    enter: function (node) {
+        // Replace it with replaced.
+        if (node.type === 'Literal')
+            return replaced;
+    }
+});
+```
+
+By passing `visitor.keys` mapping, we can extend estraverse traversing functionality.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Extending the existing traversing rules.
+    keys: {
+        // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
+        TestExpression: ['argument']
+    }
+});
+```
+
+By passing `visitor.fallback` option, we can control the behavior when encountering unknown nodes.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Iterating the child **nodes** of unknown nodes.
+    fallback: 'iteration'
+});
+```
+
+When `visitor.fallback` is a function, we can determine which keys to visit on each node.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Skip the `argument` property of each node
+    fallback: function(node) {
+        return Object.keys(node).filter(function(key) {
+            return key !== 'argument';
+        });
+    }
+});
+```

+# lru cache
+
+A cache object that deletes the least-recently-used items.
+
+[![Build Status](https://travis-ci.org/isaacs/node-lru-cache.svg?branch=master)](https://travis-ci.org/isaacs/node-lru-cache) [![Coverage Status](https://coveralls.io/repos/isaacs/node-lru-cache/badge.svg?service=github)](https://coveralls.io/github/isaacs/node-lru-cache)
+
+## Installation:
+
+```javascript
+npm install lru-cache --save
+```
+
+## Usage:
+
+```javascript
+var LRU = require("lru-cache")
+  , options = { max: 500
+              , length: function (n, key) { return n * 2 + key.length }
+              , dispose: function (key, n) { n.close() }
+              , maxAge: 1000 * 60 * 60 }
+  , cache = new LRU(options)
+  , otherCache = new LRU(50) // sets just the max size
+
+cache.set("key", "value")
+cache.get("key") // "value"
+
+// non-string keys ARE fully supported
+// but note that it must be THE SAME object, not
+// just a JSON-equivalent object.
+var someObject = { a: 1 }
+cache.set(someObject, 'a value')
+// Object keys are not toString()-ed
+cache.set('[object Object]', 'a different value')
+assert.equal(cache.get(someObject), 'a value')
+// A similar object with same keys/values won't work,
+// because it's a different object identity
+assert.equal(cache.get({ a: 1 }), undefined)
+
+cache.reset()    // empty the cache
+```
+
+If you put more stuff in it, then items will fall out.
+
+If you try to put an oversized thing in it, then it'll fall out right
+away.
+
+## Options
+
+* `max` The maximum size of the cache, checked by applying the length
+  function to all values in the cache.  Not setting this is kind of
+  silly, since that's the whole purpose of this lib, but it defaults
+  to `Infinity`.  Setting it to a non-number or negative number will
+  throw a `TypeError`.  Setting it to 0 makes it be `Infinity`.
+* `maxAge` Maximum age in ms.  Items are not pro-actively pruned out
+  as they age, but if you try to get an item that is too old, it'll
+  drop it and return undefined instead of giving it to you.
+  Setting this to a negative value will make everything seem old!
+  Setting it to a non-number will throw a `TypeError`.
+* `length` Function that is used to calculate the length of stored
+  items.  If you're storing strings or buffers, then you probably want
+  to do something like `function(n, key){return n.length}`.  The default is
+  `function(){return 1}`, which is fine if you want to store `max`
+  like-sized things.  The item is passed as the first argument, and
+  the key is passed as the second argumnet.
+* `dispose` Function that is called on items when they are dropped
+  from the cache.  This can be handy if you want to close file
+  descriptors or do other cleanup tasks when items are no longer
+  accessible.  Called with `key, value`.  It's called *before*
+  actually removing the item from the internal cache, so if you want
+  to immediately put it back in, you'll have to do that in a
+  `nextTick` or `setTimeout` callback or it won't do anything.
+* `stale` By default, if you set a `maxAge`, it'll only actually pull
+  stale items out of the cache when you `get(key)`.  (That is, it's
+  not pre-emptively doing a `setTimeout` or anything.)  If you set
+  `stale:true`, it'll return the stale value before deleting it.  If
+  you don't set this, then it'll return `undefined` when you try to
+  get a stale entry, as if it had already been deleted.
+* `noDisposeOnSet` By default, if you set a `dispose()` method, then
+  it'll be called whenever a `set()` operation overwrites an existing
+  key.  If you set this option, `dispose()` will only be called when a
+  key falls out of the cache, not when it is overwritten.
+* `updateAgeOnGet` When using time-expiring entries with `maxAge`,
+  setting this to `true` will make each item's effective time update
+  to the current time whenever it is retrieved from cache, causing it
+  to not expire.  (It can still fall out of cache based on recency of
+  use, of course.)
+
+## API
+
+* `set(key, value, maxAge)`
+* `get(key) => value`
+
+    Both of these will update the "recently used"-ness of the key.
+    They do what you think. `maxAge` is optional and overrides the
+    cache `maxAge` option if provided.
+
+    If the key is not found, `get()` will return `undefined`.
+
+    The key and val can be any value.
+
+* `peek(key)`
+
+    Returns the key value (or `undefined` if not found) without
+    updating the "recently used"-ness of the key.
+
+    (If you find yourself using this a lot, you *might* be using the
+    wrong sort of data structure, but there are some use cases where
+    it's handy.)
+
+* `del(key)`
+
+    Deletes a key out of the cache.
+
+* `reset()`
+
+    Clear the cache entirely, throwing away all values.
+
+* `has(key)`
+
+    Check if a key is in the cache, without updating the recent-ness
+    or deleting it for being stale.
+
+* `forEach(function(value,key,cache), [thisp])`
+
+    Just like `Array.prototype.forEach`.  Iterates over all the keys
+    in the cache, in order of recent-ness.  (Ie, more recently used
+    items are iterated over first.)
+
+* `rforEach(function(value,key,cache), [thisp])`
+
+    The same as `cache.forEach(...)` but items are iterated over in
+    reverse order.  (ie, less recently used items are iterated over
+    first.)
+
+* `keys()`
+
+    Return an array of the keys in the cache.
+
+* `values()`
+
+    Return an array of the values in the cache.
+
+* `length`
+
+    Return total length of objects in cache taking into account
+    `length` options function.
+
+* `itemCount`
+
+    Return total quantity of objects currently in cache. Note, that
+    `stale` (see options) items are returned as part of this item
+    count.
+
+* `dump()`
+
+    Return an array of the cache entries ready for serialization and usage
+    with 'destinationCache.load(arr)`.
+
+* `load(cacheEntriesArray)`
+
+    Loads another cache entries array, obtained with `sourceCache.dump()`,
+    into the cache. The destination cache is reset before loading new entries
+
+* `prune()`
+
+    Manually iterates over the entire cache proactively pruning old entries

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.minVersion('>=1.0.0') // '1.0.0'
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'

+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-n <0|1>
+        This is the base to be used for the prerelease identifier.
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+--rtl
+        Coerce version strings right to left
+
+--ltr
+        Coerce version strings left to right (default)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and
+would match the versions `2.0.0` and `3.1.0`, but not the versions
+`1.0.1` or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for the purpose of range
+matching) by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+#### Prerelease Identifier Base
+
+The method `.inc` takes an optional parameter 'identifierBase' string
+that will let you let your prerelease number as zero-based or one-based.
+Set to `false` to omit the prerelease number altogether.
+If you do not specify this parameter, it will default to zero-based.
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta', '1')
+// '1.2.4-beta.1'
+```
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta', false)
+// '1.2.4-beta'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta -n 1
+1.2.4-beta.1
+```
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta -n false
+1.2.4-beta
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless
+  `includePrerelease` is specified, in which case any version at all
+  satisfies)
+* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0-0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0-0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0-0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0-0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0-0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0-0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0-0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero element in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0-0`
+* `^0.2.3` := `>=0.2.3 <0.3.0-0`
+* `^0.0.3` := `>=0.0.3 <0.0.4-0`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0-0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4-0`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0-0`
+* `^0.0.x` := `>=0.0.0 <0.1.0-0`
+* `^0.0` := `>=0.0.0 <0.1.0-0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0-0`
+* `^0.x` := `>=0.0.0 <1.0.0-0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`  Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`  Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+  a `SemVer` object or `null`.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
+  are equal.  Sorts in ascending order if passed to `Array.sort()`.
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can possibly match
+  the given range.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+* `simplifyRange(versions, range)`: Return a "simplified" range that
+  matches the same items in `versions` list as the range specified.  Note
+  that it does *not* guarantee that it would match the same versions in all
+  cases, only for the set of versions provided.  This is useful when
+  generating ranges by joining together multiple versions with `||`
+  programmatically, to provide the user with something a bit more
+  ergonomic.  If the provided range is shorter in string-length than the
+  generated range, then that is returned.
+* `subset(subRange, superRange)`: Return `true` if the `subRange` range is
+  entirely contained by the `superRange` range.
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version, options)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string, and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
+is not valid).  The maximum  length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
+semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).
+
+If the `options.rtl` flag is set, then `coerce` will return the right-most
+coercible tuple that does not share an ending index with a longer coercible
+tuple.  For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
+`4.0.0`.  `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
+any other overlapping SemVer tuple.
+
+### Clean
+
+* `clean(version)`: Clean a string to be a valid semver if possible
+
+This will return a cleaned and trimmed semver version. If the provided
+version is not valid a null will be returned. This does not work for
+ranges.
+
+ex.
+* `s.clean(' = v 2.1.5foo')`: `null`
+* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean(' = v 2.1.5-foo')`: `null`
+* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean('=v2.1.5')`: `'2.1.5'`
+* `s.clean('  =v2.1.5')`: `2.1.5`
+* `s.clean('      2.1.5   ')`: `'2.1.5'`
+* `s.clean('~1.0.0')`: `null`
+
+## Constants
+
+As a convenience, helper constants are exported to provide information about what `node-semver` supports:
+
+### `RELEASE_TYPES`
+
+- major
+- premajor
+- minor
+- preminor
+- patch
+- prepatch
+- prerelease
+
+```
+const semver = require('semver');
+
+if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) {
+  console.log('This is a valid release type!');
+} else {
+  console.warn('This is NOT a valid release type!');
+}
+```
+
+### `SEMVER_SPEC_VERSION`
+
+2.0.0
+
+```
+const semver = require('semver');
+
+console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION);
+```
+

+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+--rtl
+        Coerce version strings right to left
+
+--ltr
+        Coerce version strings left to right (default)
+
+-n <base>
+        Base number to be used for the prerelease identifier.
+        Can be either 0 or 1, or false to omit the number altogether.
+        Defaults to 0.
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.`)
