+# svg/sax
+
+A maintained fork of [sax-js](https://github.com/isaacs/sax-js) sax-style parser for XML and HTML.
+
+Designed with [node](http://nodejs.org/) in mind, but should work fine in
+the browser or other CommonJS implementations.
+
+## What This Is
+
+* A very simple tool to parse through an XML string.
+* A stepping stone to a streaming HTML parser.
+* A handy way to deal with RSS and other mostly-ok-but-kinda-broken XML
+ docs.
+
+## What This Is (probably) Not
+
+* An HTML Parser - That's a fine goal, but this isn't it. It's just
+ XML.
+* A DOM Builder - You can use it to build an object model out of XML,
+ but it doesn't do that out of the box.
+* XSLT - No DOM = no querying.
+* 100% Compliant with (some other SAX implementation) - Most SAX
+ implementations are in Java and do a lot more than this does.
+* An XML Validator - It does a little validation when in strict mode, but
+ not much.
+* A Schema-Aware XSD Thing - Schemas are an exercise in fetishistic
+ masochism.
+* A DTD-aware Thing - Fetching DTDs is a much bigger job.
+
+## Regarding `<!DOCTYPE`s and `<!ENTITY`s
+
+The parser will handle the basic XML entities in text nodes and attribute
+values: `& < > ' "`. It's possible to define additional
+entities in XML by putting them in the DTD. This parser doesn't do anything
+with that. If you want to listen to the `ondoctype` event, and then fetch
+the doctypes, and read the entities and add them to `parser.ENTITIES`, then
+be my guest.
+
+Unknown entities will fail in strict mode, and in loose mode, will pass
+through unmolested.
+
+## Usage
+
+```javascript
+var sax = require("./lib/sax"),
+ strict = true, // set to false for html-mode
+ parser = sax.parser(strict);
+
+parser.onerror = function (e) {
+ // an error happened.
+};
+parser.ontext = function (t) {
+ // got some text. t is the string of text.
+};
+parser.onopentag = function (node) {
+ // opened a tag. node has "name" and "attributes"
+};
+parser.onattribute = function (attr) {
+ // an attribute. attr has "name" and "value"
+};
+parser.onend = function () {
+ // parser stream is done, and ready to have more stuff written to it.
+};
+
+parser.write('<xml>Hello, <who name="world">world</who>!</xml>').close();
+```
+
+
+## Arguments
+
+Pass the following arguments to the parser function. All are optional.
+
+`strict` - Boolean. Whether or not to be a jerk. Default: `false`.
+
+`opt` - Object bag of settings regarding string formatting. All default to `false`.
+
+Settings supported:
+
+* `trim` - Boolean. Whether or not to trim text and comment nodes.
+* `normalize` - Boolean. If true, then turn any whitespace into a single
+ space.
+* `lowercase` - Boolean. If true, then lowercase tag names and attribute names
+ in loose mode, rather than uppercasing them.
+* `xmlns` - Boolean. If true, then namespaces are supported.
+* `position` - Boolean. If false, then don't track line/col/position.
+* `strictEntities` - Boolean. If true, only parse [predefined XML
+ entities](http://www.w3.org/TR/REC-xml/#sec-predefined-ent)
+ (`&`, `'`, `>`, `<`, and `"`)
+
+## Methods
+
+`write` - Write bytes onto the stream. You don't have to do this all at
+once. You can keep writing as much as you want.
+
+`close` - Close the stream. Once closed, no more data may be written until
+it is done processing the buffer, which is signaled by the `end` event.
+
+`resume` - To gracefully handle errors, assign a listener to the `error`
+event. Then, when the error is taken care of, you can call `resume` to
+continue parsing. Otherwise, the parser will not continue while in an error
+state.
+
+## Members
+
+At all times, the parser object will have the following members:
+
+`line`, `column`, `position` - Indications of the position in the XML
+document where the parser currently is looking.
+
+`startTagPosition` - Indicates the position where the current tag starts.
+
+`closed` - Boolean indicating whether or not the parser can be written to.
+If it's `true`, then wait for the `ready` event to write again.
+
+`strict` - Boolean indicating whether or not the parser is a jerk.
+
+`opt` - Any options passed into the constructor.
+
+`tag` - The current tag being dealt with.
+
+And a bunch of other stuff that you probably shouldn't touch.
+
+## Events
+
+All events emit with a single argument. To listen to an event, assign a
+function to `on<eventname>`. Functions get executed in the this-context of
+the parser object. The list of supported events are also in the exported
+`EVENTS` array.
+
+`error` - Indication that something bad happened. The error will be hanging
+out on `parser.error`, and must be deleted before parsing can continue. By
+listening to this event, you can keep an eye on that kind of stuff. Note:
+this happens *much* more in strict mode. Argument: instance of `Error`.
+
+`text` - Text node. Argument: string of text.
+
+`doctype` - The `<!DOCTYPE` declaration. Argument: doctype string.
+
+`processinginstruction` - Stuff like `<?xml foo="blerg" ?>`. Argument:
+object with `name` and `body` members. Attributes are not parsed, as
+processing instructions have implementation dependent semantics.
+
+`sgmldeclaration` - Random SGML declarations. Stuff like `<!ENTITY p>`
+would trigger this kind of event. This is a weird thing to support, so it
+might go away at some point. SAX isn't intended to be used to parse SGML,
+after all.
+
+`opentagstart` - Emitted immediately when the tag name is available,
+but before any attributes are encountered. Argument: object with a
+`name` field and an empty `attributes` set. Note that this is the
+same object that will later be emitted in the `opentag` event.
+
+`opentag` - An opening tag. Argument: object with `name` and `attributes`.
+In non-strict mode, tag names are uppercased, unless the `lowercase`
+option is set. If the `xmlns` option is set, then it will contain
+namespace binding information on the `ns` member, and will have a
+`local`, `prefix`, and `uri` member.
+
+`closetag` - A closing tag. In loose mode, tags are auto-closed if their
+parent closes. In strict mode, well-formedness is enforced. Note that
+self-closing tags will have `closeTag` emitted immediately after `openTag`.
+Argument: tag name.
+
+`attribute` - An attribute node. Argument: object with `name` and `value`.
+In non-strict mode, attribute names are uppercased, unless the `lowercase`
+option is set. If the `xmlns` option is set, it will also contains namespace
+information.
+
+`comment` - A comment node. Argument: the string of the comment.
+
+`opencdata` - The opening tag of a `<![CDATA[` block.
+
+`cdata` - The text of a `<![CDATA[` block. Since `<![CDATA[` blocks can get
+quite large, this event may fire multiple times for a single block, if it
+is broken up into multiple `write()`s. Argument: the string of random
+character data.
+
+`closecdata` - The closing tag (`]]>`) of a `<![CDATA[` block.
+
+`opennamespace` - If the `xmlns` option is set, then this event will
+signal the start of a new namespace binding.
+
+`closenamespace` - If the `xmlns` option is set, then this event will
+signal the end of a namespace binding.
+
+`end` - Indication that the closed stream has ended.
+
+`ready` - Indication that the stream has reset, and is ready to be written
+to.
+
+`noscript` - In non-strict mode, `<script>` tags trigger a `"script"`
+event, and their contents are not checked for special xml characters.
+If you pass `noscript: true`, then this behavior is suppressed.
+
+## Reporting Problems
+
+It's best to write a failing test if you find an issue. I will always
+accept pull requests with failing tests if they demonstrate intended
+behavior, but it is very hard to figure out what issue you're describing
+without a test. Writing a test is also the best way for you yourself
+to figure out if you really understand the issue you think you have with
+sax-js.

+# Rollup Plugin import-meta-assets
+
+Rollup plugin that detects assets references relative to modules using patterns such as `new URL('./assets/my-img.png', import.meta.url)`.
+
+The referenced assets are added to the rollup pipeline, allowing them to be transformed and hash the filenames.
+
+## How it works
+
+A common pattern is to import an asset to get the URL of it after bundling:
+
+```js
+import myImg from './assets/my-img.png';
+```
+
+This doesn't work in the browser without transformation. This plugin makes it possible to use an identical pattern using `import.meta.url` which does work in the browser:
+
+```js
+const myImg = new URL('./assets/my-img.png', import.meta.url);
+```
+
+## Install
+
+Using npm:
+
+```
+npm install @web/rollup-plugin-import-meta-assets --save-dev
+```
+
+## Usage
+
+Create a rollup.config.js [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
+
+```js
+import { importMetaAssets } from '@web/rollup-plugin-import-meta-assets';
+
+export default {
+ input: 'src/index.js',
+ output: {
+ dir: 'output',
+ format: 'es',
+ },
+ plugins: [importMetaAssets()],
+};
+```
+
+Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
+

+# @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?: <picomatch>, exclude?: <picomatch>, options?: Object)`<br>
+Returns: `String`
+
+#### `include` and `exclude`
+
+Type: `String | RegExp | Array[...String|RegExp]`<br>
+
+A valid [`picomatch`](https://github.com/micromatch/picomatch#globbing-features) 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 `picomatch` patterns, and must not match any of the `options.exclude` patterns.
+
+Note that `picomatch` patterns are very similar to [`minimatch`](https://github.com/isaacs/minimatch#readme) patterns, and in most use cases, they are interchangeable. If you have more specific pattern matching needs, you can view [this comparison table](https://github.com/micromatch/picomatch#library-comparisons) to learn more about where the libraries differ.
+
+#### `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',

+ 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

+#boolbase
+This very simple module provides two basic functions, one that always returns true (`trueFunc`) and one that always returns false (`falseFunc`).
+
+###WTF?
+
+By having only a single instance of these functions around, it's possible to do some nice optimizations. Eg. [`CSSselect`](https://github.com/fb55/CSSselect) uses these functions to determine whether a selector won't match any elements. If that's the case, the DOM doesn't even have to be touched.
+
+###And why is this a separate module?
+
+I'm trying to modularize `CSSselect` and most modules depend on these functions. IMHO, having a separate module is the easiest solution to this problem.

+
+a CSS selector compiler/engine
+
+## What?
+
+css-select turns CSS selectors into functions that tests if elements match them. When searching for elements, testing is executed "from the top", similar to how browsers execute CSS selectors.
+
+In its default configuration, css-select queries the DOM structure of the [`domhandler`](https://github.com/fb55/domhandler) module (also known as htmlparser2 DOM).
+It uses [`domutils`](https://github.com/fb55/domutils) as its default adapter over the DOM structure. See Options below for details on querying alternative DOM structures.
+
+**Features:**
+
+- Full implementation of CSS3 selectors
+- Partial implementation of jQuery/Sizzle extensions
+- Very high test coverage
+- Pretty good performance
+
+## Why?
+
+The traditional approach of executing CSS selectors, named left-to-right execution, is to execute every component of the selector in order, from left to right _(duh)_. The execution of the selector `a b` for example will first query for `a` elements, then search these for `b` elements. (That's the approach of eg. [`Sizzle`](https://github.com/jquery/sizzle), [`nwmatcher`](https://github.com/dperini/nwmatcher/) and [`qwery`](https://github.com/ded/qwery).)
+
+While this works, it has some downsides: Children of `a`s will be checked multiple times; first, to check if they are also `a`s, then, for every superior `a` once, if they are `b`s. Using [Big O notation](http://en.wikipedia.org/wiki/Big_O_notation), that would be `O(n^(k+1))`, where `k` is the number of descendant selectors (that's the space in the example above).
+
+The far more efficient approach is to first look for `b` elements, then check if they have superior `a` elements: Using big O notation again, that would be `O(n)`. That's called right-to-left execution.
+
+And that's what css-select does – and why it's quite performant.
+
+## How does it work?
+
+By building a stack of functions.
+
+_Wait, what?_
+
+Okay, so let's suppose we want to compile the selector `a b` again, for right-to-left execution. We start by _parsing_ the selector, which means we turn the selector into an array of the building-blocks of the selector, so we can distinguish them easily. That's what the [`css-what`](https://github.com/fb55/css-what) module is for, if you want to have a look.
+
+Anyway, after parsing, we end up with an array like this one:
+
+```js
+[
+ { type: "tag", name: "a" },
+ { type: "descendant" },
+ { type: "tag", name: "b" },
+];
+```
+
+Actually, this array is wrapped in another array, but that's another story (involving commas in selectors).
+
+Now that we know the meaning of every part of the selector, we can compile it. That's where it becomes interesting.
+
+The basic idea is to turn every part of the selector into a function, which takes an element as its only argument. The function checks whether a passed element matches its part of the selector: If it does, the element is passed to the next turned-into-a-function part of the selector, which does the same. If an element is accepted by all parts of the selector, it _matches_ the selector and double rainbow ALL THE WAY.
+
+As said before, we want to do right-to-left execution with all the big O improvements nonsense, so elements are passed from the rightmost part of the selector (`b` in our example) to the leftmost (~~which would be `c`~~ of course `a`).
+
+_//TODO: More in-depth description. Implementation details. Build a spaceship._
+
+## API
+
+```js
+const CSSselect = require("css-select");
+```
+
+**Note:** css-select throws errors when invalid selectors are passed to it, contrary to the behavior in browsers, which swallow them. This is done to aid with writing css selectors, but can be unexpected when processing arbitrary strings.
+
+#### `CSSselect.selectAll(query, elems, options)`
+
+Queries `elems`, returns an array containing all matches.
+
+- `query` can be either a CSS selector or a function.
+- `elems` can be either an array of elements, or a single element. If it is an element, its children will be queried.
+- `options` is described below.
+
+Aliases: `default` export, `CSSselect.iterate(query, elems)`.
+
+#### `CSSselect.compile(query)`
+
+Compiles the query, returns a function.
+
+#### `CSSselect.is(elem, query, options)`
+
+Tests whether or not an element is matched by `query`. `query` can be either a CSS selector or a function.
+
+#### `CSSselect.selectOne(query, elems, options)`
+
+Arguments are the same as for `CSSselect.selectAll(query, elems)`.
+Only returns the first match, or `null` if there was no match.
+
+### Options
+
+- `xmlMode`: When enabled, tag names will be case-sensitive. Default: `false`.
+- `strict`: Limits the module to only use CSS3 selectors. Default: `false`.
+- `rootFunc`: The last function in the stack, will be called with the last element that's looked at. Should return `true`.
+- `adapter`: The adapter to use when interacting with the backing DOM structure. By default it uses [`domutils`](https://github.com/fb55/domutils).
+
+#### Custom Adapters
+
+A custom adapter must implement the following functions:
+
+```
+isTag, existsOne, getAttributeValue, getChildren, getName, getParent,
+getSiblings, getText, hasAttrib, removeSubsets, findAll, findOne
+```
+
+The method signature notation used below should be fairly intuitive - if not,
+see the [`TypeScript`](https://www.typescriptlang.org/) docs, as it is very similar to both of those.
+You may also want to look at [`domutils`](https://github.com/fb55/domutils) to see the default
+implementation, or at [`css-select-browser-adapter`](https://github.com/nrkn/css-select-browser-adapter/blob/master/index.js)
+for an implementation backed by the DOM.
+
+```ts
+interface Adapter<Node, ElementNode extends Node> {
+ /**
+ * Is the node a tag?
+ */
+ isTag: (node: Node) => node is ElementNode;
+
+ /**
+ * Does at least one of passed element nodes pass the test predicate?
+ */
+ existsOne: (test: Predicate<ElementNode>, elems: Node[]) => boolean;
+
+ /**
+ * Get the attribute value.
+ */
+ getAttributeValue: (elem: ElementNode, name: string) => string | undefined;
+
+ /**
+ * Get the node's children
+ */
+ getChildren: (node: Node) => Node[];
+
+ /**
+ * Get the name of the tag
+ */
+ getName: (elem: ElementNode) => string;
+
+ /**
+ * Get the parent of the node
+ */
+ getParent: (node: ElementNode) => ElementNode | null;
+
+ /**
+ * Get the siblings of the node. Note that unlike jQuery's `siblings` method,
+ * this is expected to include the current node as well
+ */
+ getSiblings: (node: Node) => Node[];
+
+ /**
+ * Get the text content of the node, and its children if it has any.
+ */
+ getText: (node: Node) => string;
+
+ /**
+ * Does the element have the named attribute?
+ */
+ hasAttrib: (elem: ElementNode, name: string) => boolean;
+
+ /**
+ * Takes an array of nodes, and removes any duplicates, as well as any
+ * nodes whose ancestors are also in the array.
+ */
+ removeSubsets: (nodes: Node[]) => Node[];
+
+ /**
+ * Finds all of the element nodes in the array that match the test predicate,
+ * as well as any of their children that match it.
+ */
+ findAll: (test: Predicate<ElementNode>, nodes: Node[]) => ElementNode[];
+
+ /**
+ * Finds the first node in the array that matches the test predicate, or one
+ * of its children.
+ */
+ findOne: (
+ test: Predicate<ElementNode>,
+ elems: Node[]
+ ) => ElementNode | null;
+
+ /**
+ * The adapter can also optionally include an equals method, if your DOM
+ * structure needs a custom equality test to compare two objects which refer
+ * to the same underlying node. If not provided, `css-select` will fall back to
+ * `a === b`.
+ */
+ equals?: (a: Node, b: Node) => boolean;
+
+ /**
+ * Is the element in hovered state?
+ */
+ isHovered?: (elem: ElementNode) => boolean;
+
+ /**
+ * Is the element in visited state?
+ */
+ isVisited?: (elem: ElementNode) => boolean;
+
+ /**
+ * Is the element in active state?
+ */
+ isActive?: (elem: ElementNode) => boolean;
+}
+```
+
+## Supported selectors
+
+_As defined by CSS 4 and / or jQuery._
+
+- Universal (`*`)
+- Tag (`<tagname>`)
+- Descendant (``)
+- Child (`>`)
+- Parent (`<`) \*
+- Sibling (`+`)
+- Adjacent (`~`)
+- Attribute (`[attr=foo]`), with supported comparisons:
+ - `[attr]` (existential)
+ - `=`
+ - `~=`
+ - `|=`
+ - `*=`
+ - `^=`
+ - `$=`
+ - `!=` \*
+ - Also, `i` can be added after the comparison to make the comparison case-insensitive (eg. `[attr=foo i]`) \*
+- Pseudos:
+ - `:not`
+ - `:contains` \*
+ - `:icontains` \* (case-insensitive version of `:contains`)
+ - `:has` \*
+ - `:root`
+ - `:empty`
+ - `:parent` \*
+ - `:[first|last]-child[-of-type]`
+ - `:only-of-type`, `:only-child`
+ - `:nth-[last-]child[-of-type]`
+ - `:link`, `:any-link`
+ - `:visited`, `:hover`, `:active` \* (these depend on optional Adapter methods, so these will work only if implemented in Adapter)
+ - `:selected` \*, `:checked`
+ - `:enabled`, `:disabled`
+ - `:required`, `:optional`
+ - `:header`, `:button`, `:input`, `:text`, `:checkbox`, `:file`, `:password`, `:reset`, `:radio` etc. \*
+ - `:matches`, `:is` \*

+# dom-serializer [](https://travis-ci.com/cheeriojs/dom-serializer)
+
+Renders a [domhandler](https://github.com/fb55/domhandler) DOM node or an array of domhandler DOM nodes to a string.
+
+```js
+import render from "dom-serializer";
+
+// OR
+
+const render = require("dom-serializer").default;
+```
+
+# API
+
+## `render`
+
+▸ **render**(`node`: Node \| Node[], `options?`: [_Options_](#Options)): _string_
+
+Renders a DOM node or an array of DOM nodes to a string.
+
+Can be thought of as the equivalent of the `outerHTML` of the passed node(s).
+
+#### Parameters:
+
+| Name | Type | Default value | Description |
+| :-------- | :--------------------------------- | :------------ | :----------------------------- |
+| `node` | Node \| Node[] | - | Node to be rendered. |
+| `options` | [_DomSerializerOptions_](#Options) | {} | Changes serialization behavior |
+
+**Returns:** _string_
+
+## Options
+
+### `decodeEntities`
+
+• `Optional` **decodeEntities**: _boolean_
+
+Encode characters that are either reserved in HTML or XML, or are outside of the ASCII range.
+
+**`default`** true
+
+---
+
+### `emptyAttrs`
+
+• `Optional` **emptyAttrs**: _boolean_
+
+Print an empty attribute's value.
+
+**`default`** xmlMode
+
+**`example`** With <code>emptyAttrs: false</code>: <code><input checked></code>
+
+**`example`** With <code>emptyAttrs: true</code>: <code><input checked=""></code>
+
+---
+
+### `selfClosingTags`
+
+• `Optional` **selfClosingTags**: _boolean_
+
+Print self-closing tags for tags without contents.
+
+**`default`** xmlMode
+
+**`example`** With <code>selfClosingTags: false</code>: <code><foo></foo></code>
+
+**`example`** With <code>selfClosingTags: true</code>: <code><foo /></code>
+
+---
+
+### `xmlMode`
+
+• `Optional` **xmlMode**: _boolean_ \| _"foreign"_
+
+Treat the input as an XML document; enables the `emptyAttrs` and `selfClosingTags` options.
+
+If the value is `"foreign"`, it will try to correct mixed-case attribute names.
+
+**`default`** false
+

+# domhandler [](https://travis-ci.com/fb55/domhandler)
+
+The DOM handler creates a tree containing all nodes of a page.
+The tree can be manipulated using the [domutils](https://github.com/fb55/domutils)
+or [cheerio](https://github.com/cheeriojs/cheerio) libraries and
+rendered using [dom-serializer](https://github.com/cheeriojs/dom-serializer) .
+
+## Usage
+
+```javascript
+const handler = new DomHandler([ <func> callback(err, dom), ] [ <obj> options ]);
+// const parser = new Parser(handler[, options]);
+```
+
+Available options are described below.
+
+## Example
+
+```javascript
+const { Parser } = require("htmlparser2");
+const { DomHandler } = require("domhandler");
+const rawHtml =
+ "Xyz <script language= javascript>var foo = '<<bar>>';</script><!--<!-- Waah! -- -->";
+const handler = new DomHandler((error, dom) => {
+ if (error) {
+ // Handle error
+ } else {
+ // Parsing completed, do something
+ console.log(dom);
+ }
+});
+const parser = new Parser(handler);
+parser.write(rawHtml);
+parser.end();
+```
+
+Output:
+
+```javascript
+[
+ {
+ data: "Xyz ",
+ type: "text",
+ },
+ {
+ type: "script",
+ name: "script",
+ attribs: {
+ language: "javascript",
+ },
+ children: [
+ {
+ data: "var foo = '<bar>';<",
+ type: "text",
+ },
+ ],
+ },
+ {
+ data: "<!-- Waah! -- ",
+ type: "comment",
+ },
+];
+```
+
+## Option: `withStartIndices`
+
+Add a `startIndex` property to nodes.
+When the parser is used in a non-streaming fashion, `startIndex` is an integer
+indicating the position of the start of the node in the document.
+The default value is `false`.
+
+## Option: `withEndIndices`
+
+Add an `endIndex` property to nodes.
+When the parser is used in a non-streaming fashion, `endIndex` is an integer
+indicating the position of the end of the node in the document.
+The default value is `false`.
+
+## Option: `normalizeWhitespace` _(deprecated)_
+
+Replace all whitespace with single spaces.
+The default value is `false`.
+
+**Note:** Enabling this might break your markup.
+
+For the following examples, this HTML will be used:
+
+```html
+<font> <br />this is the text <font></font></font>
+```
+
+### Example: `normalizeWhitespace: true`
+
+```javascript
+[
+ {

+
+## 1.0.0-alpha.37 (October 22, 2019)
+
+- Bumped `source-map` version to `^0.6.1` to fix source map generation inconsistency across node.js versions due to mappings sorting bug and v8 moving to [a stable Array#sort](https://v8.dev/blog/array-sort) ([fix commit](https://github.com/mozilla/source-map/commit/f35a2e4212dd025cb5e1fc219e7ac8a4b96c2cc9) in `source-map`)

+
+- Dropped support for Node < 8
+- Updated dev deps (fixed `npm audit` issues)
+- Reworked build pipeline
+ - Package provides `dist/csstree.js` and `dist/csstree.min.js` now (instead of single `dist/csstree.js` that was a min version)
+ - Bundle size (min version) reduced from 191Kb to 158Kb due to some optimisations
+- Definition syntax
+ - Renamed `grammar` into `definitionSyntax` (named per spec)
+ - Added `compact` option to `generate()` method to avoid formatting (spaces) when possible

+
+## 1.0.0-alpha.35 (October 7, 2019)
+
+- Walker

+ - Added `find()`, `findLast()` and `findAll()` methods (e.g. `csstree.find(ast, node => node.type === 'ClassSelector')`)
+
+## 1.0.0-alpha.34 (July 27, 2019)
+
+- Tokenizer
+ - Added `isBOM()` function
+ - Added `charCodeCategory()` function
+ - Removed `firstCharOffset()` function (use `isBOM()` instead)
+ - Removed `CHARCODE` dictionary
+ - Removed `INPUT_STREAM_CODE*` dictionaries
+- Lexer
+ - Allowed comments in matching value (just ignore them like whitespaces)
+ - Increased iteration count in value matching from 10k up to 15k
+ - Fixed missed `debugger` (#104)
+
+## 1.0.0-alpha.33 (July 11, 2019)
+
+- Lexer
+ - Fixed low priority productions matching by changing an approach for robust one (#103)
+
+## 1.0.0-alpha.32 (July 11, 2019)
+
+- Lexer
+ - Fixed low priority productions matching in long `||-` and `&&-` groups (#103)
+
+## 1.0.0-alpha.31 (July 11, 2019)
+
+- Bumped `mdn/data` to `2.0.4` (#99)
+- Lexer
+ - Added [bracketed range notation](https://drafts.csswg.org/css-values-4/#numeric-ranges) support and related refactoring
+ - Removed `<number-zero-one>`, `<number-one-or-greater>` and `<positive-integer>` from generic types. In fact, types moved to patch, because those types can be expressed in a regular grammar due to bracketed range notation implemented
+ - Added support for multiple token string matching
+ - Improved `<custom-ident>` production matching to claim the keyword only if no other unfulfilled production can claim it (#101)
+ - Improved `<length>` production matching to claim "unitless zero" only if no other unfulfilled production can claim it
+ - Changed lexer's constructor to prevent generic types override when used
+ - Fixed large `||`- and `&&`-group matching, matching continues from the beginning on term match (#85)
+ - Fixed checking that value has `var()` occurrences when value is a string (such values can't be matched on syntax currently and fail with specific error that can be used for ignorance in validation tools)
+ - Fixed `<declaration-value>` and `<any-value>` matching when a value contains a function, parentheses or braces
+
+## 1.0.0-alpha.30 (July 3, 2019)
+
+- Bumped `mdn/data` to `~2.0.3`
+ - Removed type removals from `mdn/data` due to lack of some generic types and specific lexer restictions (since lexer was reworked, see below)
+ - Reduced and updated patches
+- Tokenizer
+ - Reworked tokenizer itself to compliment [CSS Syntax Module Level 3](https://drafts.csswg.org/css-syntax/#tokenization)
+ - `Tokenizer` class splitted into several abstractions:
+ - Added `TokenStream` class
+ - Added `OffsetToLocation` class
+ - Added `tokenize()` function that creates `TokenStream` instance for given string or updates a `TokenStream` instance passed as second parameter
+ - Removed `Tokenizer` class
+ - Removed `Raw` token type
+ - Renamed `Identifier` token type to `Ident`
+ - Added token types: `Hash`, `BadString`, `BadUrl`, `Delim`, `Percentage`, `Dimension`, `Colon`, `Semicolon`, `Comma`, `LeftSquareBracket`, `RightSquareBracket`, `LeftParenthesis`, `RightParenthesis`, `LeftCurlyBracket`, `RightCurlyBracket`
+ - Replaced `Punctuator` with `Delim` token type, that excludes specific characters with its own token type like `Colon`, `Semicolon` etc
+ - Removed `findCommentEnd`, `findStringEnd`, `findDecimalNumberEnd`, `findNumberEnd`, `findEscapeEnd`, `findIdentifierEnd` and `findUrlRawEnd` helper function
+ - Removed `SYMBOL_TYPE`, `PUNCTUATION` and `STOP_URL_RAW` dictionaries
+ - Added `isDigit`, `isHexDigit`, `isUppercaseLetter`, `isLowercaseLetter`, `isLetter`, `isNonAscii`, `isNameStart`, `isName`, `isNonPrintable`, `isNewline`, `isWhiteSpace`, `isValidEscape`, `isIdentifierStart`, `isNumberStart`, `consumeEscaped`, `consumeName`, `consumeNumber` and `consumeBadUrlRemnants` helper functions
+- Parser
+ - Changed parsing algorithms to work with new token type set
+ - Changed `HexColor` consumption in way to relax checking a value, i.e. now `value` is a sequence of one or more name chars
+ - Added `&` as a property hack
+ - Relaxed `var()` parsing to only check that a first arguments is an identifier (not a custom property name as before)
+- Lexer
+ - Reworked syntax matching to relay on token set only (having AST is optional now)
+ - Extended `Lexer#match()`, `Lexer#matchType()` and `Lexer#matchProperty()` methods to take a string as value, beside AST as a value
+ - Extended `Lexer#match()` method to take a string as a syntax, beside of syntax descriptor
+ - Reworked generic types:
+ - Removed `<attr()>`, `<url>` (moved to patch) and `<progid>` types
+ - Added types:
+ - Related to token types: `<ident-token>`, `<function-token>`, `<at-keyword-token>`, `<hash-token>`, `<string-token>`, `<bad-string-token>`, `<url-token>`, `<bad-url-token>`, `<delim-token>`, `<number-token>`, `<percentage-token>`, `<dimension-token>`, `<whitespace-token>`, `<CDO-token>`, `<CDC-token>`, `<colon-token>`, `<semicolon-token>`, `<comma-token>`, `<[-token>`, `<]-token>`, `<(-token>`, `<)-token>`, `<{-token>` and `<}-token>`
+ - Complex types: `<an-plus-b>`, `<urange>`, `<custom-property-name>`, `<declaration-value>`, `<any-value>` and `<zero>`
+ - Renamed `<unicode-range>` to `<urange>` as per spec
+ - Renamed `<expression>` (IE legacy extension) to `<-ms-legacy-expression>` and may to be removed in next releases
+
+## 1.0.0-alpha.29 (May 30, 2018)
+
+- Lexer
+ - Syntax matching was completely reworked. Now it's token-based and uses state machine. Public API has not changed. However, some internal data structures have changed. Most significal change in syntax match result tree structure, it's became token-based instead of node-based.
+ - Grammar
+ - Changed grammar tree format:
+ - Added `Token` node type to represent a single code point (`<delim-token>`)
+ - Added `Multiplier` that wraps a single node (`term` property)
+ - Added `AtKeyword` to represent `<at-keyword-token>`

+ - Changed `Function` to represent `<function-token>` with no children
+ - Removed `multiplier` property from `Group`
+ - Changed `generate()` method:
+ - Method takes an `options` as second argument now (`generate(node, forceBraces, decorator)` -> `generate(node, options)`). Two options are supported: `forceBraces` and `decorator`
+ - When a second parameter is a function it treats as `decorate` option value, i.e. `generate(node, fn)` -> `generate(node, { decorate: fn })`
+ - Decorate function invokes with additional parameter – a reference to a node
+- Tokenizer
+ - Renamed `Atrule` const to `AtKeyword`
+
+## 1.0.0-alpha.28 (February 19, 2018)
+

+
+## 1.0.0-alpha.27 (January 14, 2018)
+
+- Generator
+ - Changed node's `generate()` methods invocation, methods now take a node as a single argument and context (i.e. `this`) that have methods: `chunk()`, `node()` and `children()`
+ - Renamed `translate()` to `generate()` and changed to take `options` argument
+ - Removed `translateMarkup(ast, enter, leave)` method, use `generate(ast, { decorator: (handlers) => { ... }})` instead
+ - Removed `translateWithSourceMap(ast)`, use `generate(ast, { sourceMap: true })` instead
+ - Changed to support for children as an array
+- Walker
+ - Changed `walk()` to take an `options` argument instead of handler, with `enter`, `leave`, `visit` and `reverse` options (`walk(ast, fn)` is still works and equivalent to `walk(ast, { enter: fn })`)
+ - Removed `walkUp(ast, fn)`, use `walk(ast, { leave: fn })`
+ - Removed `walkRules(ast, fn)`, use `walk(ast, { visit: 'Rule', enter: fn })` instead
+ - Removed `walkRulesRight(ast, fn)`, use `walk(ast, { visit: 'Rule', reverse: true, enter: fn })` instead
+ - Removed `walkDeclarations(ast, fn)`, use `walk(ast, { visit: 'Declaration', enter: fn })` instead
+ - Changed to support for children as array in most cases (`reverse: true` will fail on arrays since they have no `forEachRight()` method)
+- Misc
+ - List
+ - Added `List#forEach()` method
+ - Added `List#forEachRight()` method
+ - Added `List#filter()` method
+ - Changed `List#map()` method to return a `List` instance instead of `Array`

+ - Added `custom` field that contain a `true` when keyword is a custom property reference
+ - Changed `property()` method
+ - Changed `name` field to include a vendor prefix
+ - Added `basename` field to contain a name without any prefixes, i.e. a hack and a vendor prefix
+ - Added `vendorPrefix()` method
+ - Added `isCustomProperty()` method
+
+## 1.0.0-alpha.26 (November 9, 2017)
+
+- Tokenizer
+ - Added `Tokenizer#isBalanceEdge()` method
+ - Removed `Tokenizer.endsWith()` method
+- Parser
+ - Made the parser tolerant to errors by default
+ - Removed `tolerant` parser option (no parsing modes anymore)
+ - Removed `property` parser option (a value parsing does not depend on property name anymore)
+ - Canceled error for a handing semicolon in a block
+ - Canceled error for unclosed `Brackets`, `Function` and `Parentheses` when EOF is reached
+ - Fixed error when prelude ends with a comment for at-rules with custom prelude consumer
+ - Relaxed at-rule parsing:
+ - Canceled error when EOF is reached after a prelude
+ - Canceled error for an at-rule with custom block consumer when at-rule has no block (just don't apply consumer in that case)
+ - Canceled error on at-rule parsing when it occurs outside prelude or block (at-rule is converting to `Raw` node)
+ - Allowed for any at-rule to have a prelude and a block, even if it's invalid per at-rule syntax (the responsibility for this check is moved to lexer, since it's possible to construct a AST with such errors)
+ - Made a declaration value a safe parsing point (i.e. error on value parsing lead to a value is turning into `Raw` node, not a declaration as before)
+ - Excluded surrounding white spaces and comments from a `Raw` node that represents a declaration value
+ - Changed `Value` parse handler to return a node only with type `Value` (previously it returned a `Raw` node in some cases)
+ - Fixed issue with `onParseError()` is not invoked for errors occured on selector or declaration value parsing in some cases
+ - Changed using of `onParseError()` to stop parsing if handler throws an exception
+- Lexer
+ - Changed `grammar.walk()` to invoke passed handler on entering to node rather than on leaving the node
+ - Improved `grammar.walk()` to take a walk handler pair as an object, i.e. `walk(node, { enter: fn, leave: fn })`
+ - Changed `Lexer#match*()` methods to take a node of any type, but with a `children` field
+ - Added `Lexer#match(syntax, node)` method
+ - Fixed `Lexer#matchType()` method to stop return a positive result for the CSS wide keywords
+
+## 1.0.0-alpha25 (October 9, 2017)
+
+- Parser
+ - Added fallback node as argument to `onParseError()` handler
+ - Fixed raw consuming in tolerant mode when selector is invalid (greedy consuming and redundant warnings)
+ - Fixed exception in tolerant mode caused by unknown at-rule with unclosed block
+ - Changed handling of semicolons:
+ - Hanging semicolon inside declaration blocks raise an error or turns into a `Raw` node in tolerant mode instead of being ignored
+ - Semicolon outside of declaration blocks opens a `Rule` node as part of selector instead of being ignored
+ - Aligned `parseAtrulePrelude` behaviour to `parseRulePrelude`
+ - Removed `Raw` node wraping into `AtrulePrelude` when `parseAtrulePrelude` is disabled
+ - Removed error emitting when at-rule has a custom prelude customer but no prelude is found (it should be validated by a lexer later)
+- Generator
+ - Fixed performance issue with `translateWithSourceMap()`, flattening the string (because of mixing building string and indexing into it) turned it into a quadratic algorithm (approximate numbers can be found in [the quiz created by this case](https://gist.github.com/lahmatiy/ea25d0e623d88ca9848384b5707d52d9))
+- Added support for a single solidus hack for `property()`
+- Minor fixes for custom errors
+
+## 1.0.0-alpha24 (September 14, 2017)
+
+- Improved CSSTree to be stable for standart build-in objects extension (#58)
+- Parser
+ - Renamed rule's `selector` to `prelude`. The reasons: [spec names this part so](https://www.w3.org/TR/css-syntax-3/#qualified-rule), and this branch can contain not only a selector (`SelectorList`) but also a raw payload (`Raw`). What's changed:
+ - Renamed `Rule.selector` to `Rule.prelude`
+ - Renamed `parseSelector` parser option to `parseRulePrelude`
+ - Removed option for selector parse in `SelectorList`
+- Lexer
+ - Fixed undefined positions in a error when match a syntax to empty or white space only value

+- Rename walker's entry point methods to be the same as CSSTree exposed methods (i.e. `walk()`, `walkUp()` etc)
+- Rename at-rule's `expression` to `prelude` (since [spec names it so](https://www.w3.org/TR/css-syntax-3/#at-rule))
+ - `AtruleExpression` node type → `AtrulePrelude`
+ - `Atrule.expression` field → `Atrule.prelude`
+ - `parseAtruleExpression` parser's option → `parseAtrulePrelude`
+ - `atruleExpression` parse context → `atrulePrelude`
+ - `atruleExpression` walk context reference → `atrulePrelude`
+
+## 1.0.0-alpha22 (September 8, 2017)
+
+- Parser
+ - Fixed exception on parsing of unclosed `{}-block` in tolerant mode
+ - Added tolerant mode support for `DeclarationList`
+ - Added standalone entry point, i.e. default parser can be used via `require('css-tree/lib/parser')` (#47)
+- Generator
+ - Changed generator to produce `+n` when `AnPlusB.a` is `+1` to be "round-trip" with parser
+ - Added standalone entry point, i.e. default generators can be used via `require('css-tree/lib/generator')`
+- Walker
+ - Added standalone entry point, i.e. default walkers can be used via `require('css-tree/lib/walker')` (#47)
+- Lexer
+ - Added `default` keyword to the list of invalid values for `<custom-ident>` (since it reversed per [spec](https://www.w3.org/TR/css-values/#custom-idents))
+- Convertors (`toPlainObject()` and `fromPlainObject()`) moved to `lib/convertor` (entry point is `require('css-tree/lib/convertor')`)
+
+## 1.0.0-alpha21 (September 5, 2017)
+
+- Tokenizer

+ - Added `idx` and `balance` fields to each token of `Tokenizer#dump()` method result
+- Parser
+ - Added `onParseError` option
+ - Reworked node parsers that consume a `Raw` node to use a new approach. Since now a `Raw` node builds in `parser#Raw()` function only
+ - Changed semantic of `parser#Raw()`, it takes 5 parameters now (it might to be changed in future)
+ - Changed `parser#tolerantParse()` to pass a start token index to fallback function instead of source offset
+ - Fixed `AtruleExpression` consuming in tolerant mode
+ - Atrule handler to convert an empty `AtruleExpression` node into `null`
+ - Changed `AtruleExpression` handler to always return a node (before it could return a `null` in some cases)
+- Lexer
+ - Fixed comma match node for `#` multiplier
+ - Added reference name to `SyntaxReferenceError`
+- Additional fixes on custom errors
+- Reduced possible corruption of base config by `syntax.fork()`
+
+## 1.0.0-alpha20 (August 28, 2017)
+
+- Tokenizer
+ - Added `Atrule` token type (`<at-rule-token>` per spec)
+ - Added `Function` token type (`<function-token>` per spec)
+ - Added `Url` token type
+ - Replaced `Tokenizer#getTypes()` method with `Tokenizer#dump()` to get all tokens as an array
+ - Renamed `Tokenizer.TYPE.Whitespace` to `Tokenizer.TYPE.WhiteSpace`
+ - Renamed `Tokenizer.findWhitespaceEnd()` to `Tokenizer.findWhiteSpaceEnd()`
+- Parser
+ - Added initial implementation of tollerant mode (turn on by passing `tolerant: true` option). In this mode parse errors are never occour and any invalid part of CSS turns into a `Raw` node. Current safe points: `Atrule`, `AtruleExpression`, `Rule`, `Selector` and `Declaration`. Feature is experimental and further improvements are planned.
+ - Changed `Atrule.expression` to contain a `AtruleExpression` node or `null` only (other node types is wrapping into a `AtruleExpression` node)
+ - Renamed `AttributeSelector.operator` to `AttributeSelector.matcher`
+- Generator
+ - `translate()` method is now can take a function as second argument, that recieves every generated chunk. When no function is passed, default handler is used, it concats all the chunks and method returns a string.
+- Lexer
+ - Used [mdn/data](https://github.com/mdn/data) package as source of lexer's grammar instead of local dictionaries
+ - Added `x` unit to `<resolution>` generic type
+ - Improved match tree:
+ - Omited Group (sequences) match nodes
+ - Omited empty match nodes (for terms with `zero or more` multipliers)
+ - Added `ASTNode` node type to contain a reference to AST node
+ - Fixed node duplication (uncompleted match were added to tree)
+ - Added AST node reference in match nodes
+ - Added comma match node by `#` multiplier
+ - Grammar
+ - Changed `translate()` function to get a handler as third argument (optional). That handler recieves result of node traslation and can be used for decoration purposes. See [example](https://github.com/csstree/docs/blob/04c65af44477b5ea05feb373482898122b2a4528/docs/syntax.html#L619-L627)

+ - Reworked group and multipliers representation in syntax tree:
+ - Replaced `Sequence` for `Group` node type (`Sequence` node type removed)

+ - Renamed `nonEmpty` Group's property to `disallowEmpty`
+ - Added optimisation for syntax tree by dropping redundant root `Group` when it contains a single `Group` term (return this `Group` as a result)
+ - Changed lexer's match functionality
+ - Changed `Lexer#matchProperty()` and `Lexer#matchType()` to return an object instead of match tree. A match tree stores in `matched` field when AST is matched to grammar successfully, otherwise an error in `error` field. The result object also has some methods to test AST node against a match tree: `getTrace()`, `isType()`, `isProperty()` and `isKeyword()`
+ - Added `Lexer#matchDeclaration()` method
+ - Removed `Lexer#lastMatchError` (error stores in match result object in `error` field)
+ - Added initial implementation of search for AST segments (new lexer methods: `Lexer#findValueSegments()`, `Lexer#findDeclarationValueSegments()` and `Lexer#findAllSegments`)
+ - Implemented `SyntaxReferenceError` for unknown property and type references
+- Renamed field in resulting object of `property()` function: `variable` → `custom`

+
+- Extended `List` class with new methods:
+ - `List#prepend(item)`
+ - `List#prependData(data)`

+
+CSSTree is a tool set for CSS: [fast](https://github.com/postcss/benchmark) detailed parser (CSS → AST), walker (AST traversal), generator (AST → CSS) and lexer (validation and matching) based on specs and browser implementations. The main goal is to be efficient and W3C specs compliant, with focus on CSS analyzing and source-to-source transforming tasks.
+
+> NOTE: The library isn't in final shape and needs further improvements (e.g. AST format and API are subjects to change in next major versions). However it's stable enough and used by projects like [CSSO](https://github.com/css/csso) (CSS minifier) and [SVGO](https://github.com/svg/svgo) (SVG optimizer) in production.
+
+## Features
+
+- **Detailed parsing with an adjustable level of detail**
+
+ By default CSSTree parses CSS as detailed as possible, i.e. each single logical part is representing with its own AST node (see [AST format](docs/ast.md) for all possible node types). The parsing detail level can be changed through [parser options](docs/parsing.md#parsesource-options), for example, you can disable parsing of selectors or declaration values for component parts.
+
+- **Tolerant to errors by design**
+
+ Parser behaves as [spec says](https://www.w3.org/TR/css-syntax-3/#error-handling): "When errors occur in CSS, the parser attempts to recover gracefully, throwing away only the minimum amount of content before returning to parsing as normal". The only thing the parser departs from the specification is that it doesn't throw away bad content, but wraps it in a special node type (`Raw`) that allows processing it later.
+
+- **Fast and efficient**
+
+ CSSTree is created with focus on performance and effective memory consumption. Therefore it's [one of the fastest CSS parsers](https://github.com/postcss/benchmark) at the moment.
+
+- **Syntax validation**
+
+ The build-in lexer can test CSS against syntaxes defined by W3C. CSSTree uses [mdn/data](https://github.com/mdn/data/) as a basis for lexer's dictionaries and extends it with vendor specific and legacy syntaxes. Lexer can only check the declaration values currently, but this feature will be extended to other parts of the CSS in the future.

+
+## Usage
+
+Install with npm:
+
+```
+> npm install css-tree
+```
+
+Basic usage:
+
+```js
+var csstree = require('css-tree');
+
+// parse CSS to AST
+var ast = csstree.parse('.example { world: "!" }');
+
+// traverse AST and modify it
+csstree.walk(ast, function(node) {
+ if (node.type === 'ClassSelector' && node.name === 'example') {
+ node.name = 'hello';
+ }
+});
+
+// generate CSS from AST
+console.log(csstree.generate(ast));
+// .hello{world:"!"}
+```
+
+Syntax matching:
+
+```js
+// parse CSS to AST as a declaration value
+var ast = csstree.parse('red 1px solid', { context: 'value' });
+
+// match to syntax of `border` property
+var matchResult = csstree.lexer.matchProperty('border', ast);
+
+// check first value node is a <color>
+console.log(matchResult.isType(ast.children.first(), 'color'));
+// true
+
+// get a type list matched to a node
+console.log(matchResult.getTrace(ast.children.first()));
+// [ { type: 'Property', name: 'border' },
+// { type: 'Type', name: 'color' },
+// { type: 'Type', name: 'named-color' },
+// { type: 'Keyword', name: 'red' } ]
+```

+# css-what [](http://travis-ci.org/fb55/css-what)
+
+a CSS selector parser
+
+## Example
+
+```js
+const CSSwhat = require("css-what")
+CSSwhat.parse("foo[bar]:baz")
+
+~> [
+ [
+ { type: "tag", name: "foo" },
+ {
+ type: "attribute",
+ name: "bar",
+ action: "exists",
+ value: "",
+ ignoreCase: false
+ },
+ { type: "pseudo", name: "baz", data: null }
+ ]
+]
+```
+
+## API
+
+**`CSSwhat.parse(selector, options)` - Parses `selector`, optionally with the passed `options`.**
+
+The function returns a two-dimensional array. The first array represents selectors separated by commas (eg. `sub1, sub2`), the second contains the relevant tokens for that selector. Possible token types are:
+
+| name | properties | example | output |
+| ---------------- | --------------------------------------- | ------------- | ---------------------------------------------------------------------------------------- |
+| `tag` | `name` | `div` | `{ type: 'tag', name: 'div' }` |
+| `universal` | - | `*` | `{ type: 'universal' }` |
+| `pseudo` | `name`, `data` | `:name(data)` | `{ type: 'pseudo', name: 'name', data: 'data' }` |
+| `pseudo` | `name`, `data` | `:name` | `{ type: 'pseudo', name: 'name', data: null }` |
+| `pseudo-element` | `name` | `::name` | `{ type: 'pseudo-element', name: 'name' }` |
+| `attribute` | `name`, `action`, `value`, `ignoreCase` | `[attr]` | `{ type: 'attribute', name: 'attr', action: 'exists', value: '', ignoreCase: false }` |
+| `attribute` | `name`, `action`, `value`, `ignoreCase` | `[attr=val]` | `{ type: 'attribute', name: 'attr', action: 'equals', value: 'val', ignoreCase: false }` |
+| `attribute` | `name`, `action`, `value`, `ignoreCase` | `[attr^=val]` | `{ type: 'attribute', name: 'attr', action: 'start', value: 'val', ignoreCase: false }` |
+| `attribute` | `name`, `action`, `value`, `ignoreCase` | `[attr$=val]` | `{ type: 'attribute', name: 'attr', action: 'end', value: 'val', ignoreCase: false }` |
+| `child` | - | `>` | `{ type: 'child' }` |
+| `parent` | - | `<` | `{ type: 'parent' }` |
+| `sibling` | - | `~` | `{ type: 'sibling' }` |
+| `adjacent` | - | `+` | `{ type: 'adjacent' }` |
+| `descendant` | - | | `{ type: 'descendant' }` |
+
+**Options:**
+
+- `lowerCaseTags`: When false, tag names will not be lowercased. Defaults to `true`.
+- `lowerCaseAttributeNames`: When false, attribute names will not be lowercased. Defaults to `true`.
+- `xmlMode`: When `true`, `xmlMode` implies both `lowerCaseTags` and `lowerCaseAttributeNames` are set to `false`.
+
+**`CSSwhat.stringify(selector)` - Turns `selector` back into a string.**

+ - Simplify block comparison (performance).
+- New method `csso.minifyBlock()` for css block compression (e.g. `style` attribute content).
+- Ruleset merge improvement: at-rules with block (like `@media` or `@supports`) now can be skipped during ruleset merge lookup if doesn't contain something prevents it.
+- FIX: Add negation (`:not()`) to pseudo signature to avoid unsafe merge (old browsers doesn't support it).
+- FIX: Check nested parts of value when compute compatibility. It fixes unsafe property merging.
+
+## 1.7.1 (March 16, 2016)
+
+- pass block mode to tokenizer for correct parsing of declarations properties with `//` hack

+- take in account `!important` when check for property overriding (#280)
+- don't merge `text-align` declarations with some values (#281)
+- add spaces around `/deep/` combinator on translate, since it together with universal selector can produce a comment
+- better keyword and property name resolving (tolerant to hacks and so on)
+- integration improvements
+ - compression log function could be customized by `logger` option for `compress()` and `minify()`
+ - make possible to set initial line and column for parser

+CSSO (CSS Optimizer) is a CSS minifier. It performs three sort of transformations: cleaning (removing redundant), compression (replacement for shorter form) and restructuring (merge of declarations, rulesets and so on). As a result your CSS becomes much smaller.

+
+Basic usage:
+
+```js
+var csso = require('csso');
+
+var minifiedCss = csso.minify('.test { color: #ff0000; }').css;
+
+console.log(minifiedCss);
+// .test{color:red}
+```
+
+CSSO is based on [CSSTree](https://github.com/csstree/csstree) to parse CSS into AST, AST traversal and to generate AST back to CSS. All `CSSTree` API is available behind `syntax` field. You may minify CSS step by step:
+
+```js
+var csso = require('csso');
+var ast = csso.syntax.parse('.test { color: #ff0000; }');
+var compressedAst = csso.syntax.compress(ast).ast;
+var minifiedCss = csso.syntax.generate(compressedAst);
+
+console.log(minifiedCss);
+// .test{color:red}
+```
+
+> Warning: CSSO uses early versions of CSSTree that still in active development. CSSO doesn't guarantee API behind `syntax` field or AST format will not change in future releases of CSSO, since it's subject to change in CSSTree. Be careful with CSSO updates if you use `syntax` API until this warning removal.
+
+### minify(source[, options])
+
+Minify `source` CSS passed as `String`.
+
+```js
+var result = csso.minify('.test { color: #ff0000; }', {
+ restructure: false, // don't change CSS structure, i.e. don't merge declarations, rulesets etc
+ debug: true // show additional debug information:
+ // true or number from 1 to 3 (greater number - more details)
+});
+
+console.log(result.css);
+// > .test{color:red}
+```
+
+Returns an object with properties:
+
+- css `String` – resulting CSS
+- map `Object` – instance of [`SourceMapGenerator`](https://github.com/mozilla/source-map#sourcemapgenerator) or `null`
+
+Options:
+
+- sourceMap
+
+ Type: `Boolean`
+ Default: `false`
+
+ Generate a source map when `true`.
+
+- filename
+
+ Type: `String`
+ Default: `'<unknown>'`
+
+ Filename of input CSS, uses for source map generation.
+
+- debug
+
+ Type: `Boolean`
+ Default: `false`
+
+ Output debug information to `stderr`.
+
+- beforeCompress
+
+ Type: `function(ast, options)` or `Array<function(ast, options)>` or `null`
+ Default: `null`
+
+ Called right after parse is run.
+
+- afterCompress
+
+ Type: `function(compressResult, options)` or `Array<function(compressResult, options)>` or `null`
+ Default: `null`
+
+ Called right after [`syntax.compress()`](#syntaxcompressast-options) is run.
+
+- Other options are the same as for [`syntax.compress()`](#syntaxcompressast-options) function.
+
+### minifyBlock(source[, options])
+
+The same as `minify()` but for list of declarations. Usually it's a `style` attribute value.
+
+```js
+var result = csso.minifyBlock('color: rgba(255, 0, 0, 1); color: #ff0000');
+
+console.log(result.css);
+// > color:red
+```
+
+### syntax.compress(ast[, options])
+
+Does the main task – compress an AST. This is CSSO's extension in CSSTree syntax API.
+
+> NOTE: `syntax.compress()` performs AST compression by transforming input AST by default (since AST cloning is expensive and needed in rare cases). Use `clone` option with truthy value in case you want to keep input AST untouched.
+
+Returns an object with properties:
+
+- ast `Object` – resulting AST
+
+Options:
+
+- restructure
+
+ Type: `Boolean`
+ Default: `true`
+
+ Disable or enable a structure optimisations.
+
+- forceMediaMerge
+
+ Type: `Boolean`
+ Default: `false`
+
+ Enables merging of `@media` rules with the same media query by splitted by other rules. The optimisation is unsafe in general, but should work fine in most cases. Use it on your own risk.
+
+- clone
+
+ Type: `Boolean`
+ Default: `false`
+
+ Transform a copy of input AST if `true`. Useful in case of AST reuse.
+
+- comments
+
+ Type: `String` or `Boolean`
+ Default: `true`
+
+ Specify what comments to leave:
+
+ - `'exclamation'` or `true` – leave all exclamation comments (i.e. `/*! .. */`)
+ - `'first-exclamation'` – remove every comment except first one
+ - `false` – remove all comments
+
+- usage
+
+ Type: `Object` or `null`
+ Default: `null`
+
+ Usage data for advanced optimisations (see [Usage data](#usage-data) for details)
+
+- logger
+
+ Type: `Function` or `null`
+ Default: `null`
+
+ Function to track every step of transformation.
+
+### Source maps
+
+To get a source map set `true` for `sourceMap` option. Additianaly `filename` option can be passed to specify source file. When `sourceMap` option is `true`, `map` field of result object will contain a [`SourceMapGenerator`](https://github.com/mozilla/source-map#sourcemapgenerator) instance. This object can be mixed with another source map or translated to string.
+
+```js
+var csso = require('csso');
+var css = fs.readFileSync('path/to/my.css', 'utf8');
+var result = csso.minify(css, {
+ filename: 'path/to/my.css', // will be added to source map as reference to source file
+ sourceMap: true // generate source map
+});
+
+console.log(result);
+// { css: '...minified...', map: SourceMapGenerator {} }
+
+console.log(result.map.toString());
+// '{ .. source map content .. }'
+```
+
+Example of generating source map with respect of source map from input CSS:
+
+```js
+var require('source-map');
+var csso = require('csso');
+var inputFile = 'path/to/my.css';
+var input = fs.readFileSync(inputFile, 'utf8');
+var inputMap = input.match(/\/\*# sourceMappingURL=(\S+)\s*\*\/\s*$/);
+var output = csso.minify(input, {
+ filename: inputFile,
+ sourceMap: true
+});
+
+// apply input source map to output
+if (inputMap) {
+ output.map.applySourceMap(
+ new SourceMapConsumer(inputMap[1]),
+ inputFile
+ )
+}
+
+// result CSS with source map
+console.log(
+ output.css +
+ '/*# sourceMappingURL=data:application/json;base64,' +
+ new Buffer(output.map.toString()).toString('base64') +
+ ' */'
+);
+```
+
+### Usage data
+
+`CSSO` can use data about how `CSS` is used in a markup for better compression. File with this data (`JSON`) can be set using `usage` option. Usage data may contain following sections:
+
+- `blacklist` – a set of black lists (see [Black list filtering](#black-list-filtering))
+- `tags` – white list of tags
+- `ids` – white list of ids
+- `classes` – white list of classes
+- `scopes` – groups of classes which never used with classes from other groups on the same element
+
+All sections are optional. Value of `tags`, `ids` and `classes` should be an array of a string, value of `scopes` should be an array of arrays of strings. Other values are ignoring.
+
+#### White list filtering
+
+`tags`, `ids` and `classes` are using on clean stage to filter selectors that contain something not in the lists. Selectors are filtering only by those kind of simple selector which white list is specified. For example, if only `tags` list is specified then type selectors are checking, and if all type selectors in selector present in list or selector has no any type selector it isn't filter.
+
+> `ids` and `classes` are case sensitive, `tags` – is not.
+
+Input CSS:
+
+```css
+* { color: green; }
+ul, ol, li { color: blue; }
+UL.foo, span.bar { color: red; }
+```
+
+Usage data:
+
+```json
+{
+ "tags": ["ul", "LI"]
+}
+```
+
+Resulting CSS:
+
+```css
+*{color:green}ul,li{color:blue}ul.foo{color:red}
+```
+
+Filtering performs for nested selectors too. `:not()` pseudos content is ignoring since the result of matching is unpredictable. Example for the same usage data as above:
+
+```css
+:nth-child(2n of ul, ol) { color: red }
+:nth-child(3n + 1 of img) { color: yellow }
+:not(div, ol, ul) { color: green }
+:has(:matches(ul, ol), ul, ol) { color: blue }
+```
+
+Turns into:
+
+```css
+:nth-child(2n of ul){color:red}:not(div,ol,ul){color:green}:has(:matches(ul),ul){color:blue}
+```
+
+#### Black list filtering
+
+Black list filtering performs the same as white list filtering, but filters things that mentioned in the lists. `blacklist` can contain the lists `tags`, `ids` and `classes`.
+
+Black list has a higher priority, so when something mentioned in the white list and in the black list then white list occurrence is ignoring. The `:not()` pseudos content ignoring as well.
+
+```css
+* { color: green; }
+ul, ol, li { color: blue; }
+UL.foo, li.bar { color: red; }
+```
+
+Usage data:
+
+```json
+{
+ "blacklist": {
+ "tags": ["ul"]
+ },
+ "tags": ["ul", "LI"]
+}
+```
+
+Resulting CSS:
+
+```css
+*{color:green}li{color:blue}li.bar{color:red}
+```
+
+#### Scopes
+
+Scopes is designed for CSS scope isolation solutions such as [css-modules](https://github.com/css-modules/css-modules). Scopes are similar to namespaces and define lists of class names that exclusively used on some markup. This information allows the optimizer to move rules more agressive. Since it assumes selectors from different scopes don't match for the same element. This can improve rule merging.
+
+Suppose we have a file:
+
+```css
+.module1-foo { color: red; }
+.module1-bar { font-size: 1.5em; background: yellow; }
+
+.module2-baz { color: red; }
+.module2-qux { font-size: 1.5em; background: yellow; width: 50px; }
+```
+
+It can be assumed that first two rules are never used with the second two on the same markup. But we can't say that for sure without a markup review. The optimizer doesn't know it either and will perform safe transformations only. The result will be the same as input but with no spaces and some semicolons:
+
+```css
+.module1-foo{color:red}.module1-bar{font-size:1.5em;background:#ff0}.module2-baz{color:red}.module2-qux{font-size:1.5em;background:#ff0;width:50px}
+```
+
+With usage data `CSSO` can produce better output. If follow usage data is provided:
+
+```json
+{
+ "scopes": [
+ ["module1-foo", "module1-bar"],
+ ["module2-baz", "module2-qux"]
+ ]
+}
+```
+
+The result will be (29 bytes extra saving):
+
+```css
+.module1-foo,.module2-baz{color:red}.module1-bar,.module2-qux{font-size:1.5em;background:#ff0}.module2-qux{width:50px}
+```
+
+If class name isn't mentioned in the `scopes` it belongs to default scope. `scopes` data doesn't affect `classes` whitelist. If class name mentioned in `scopes` but missed in `classes` (both sections are specified) it will be filtered.
+
+Note that class name can't be set for several scopes. Also a selector can't have class names from different scopes. In both cases an exception will thrown.
+
+Currently the optimizer doesn't care about changing order safety for out-of-bounds selectors (i.e. selectors that match to elements without class name, e.g. `.scope div` or `.scope ~ :last-child`). It assumes that scoped CSS modules doesn't relay on it's order. It may be fix in future if to be an issue.

+CC0 1.0 Universal
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator and
+subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for the
+purpose of contributing to a commons of creative, cultural and scientific
+works ("Commons") that the public can reliably and without fear of later
+claims of infringement build upon, modify, incorporate in other works, reuse
+and redistribute as freely as possible in any form whatsoever and for any
+purposes, including without limitation commercial purposes. These owners may
+contribute to the Commons to promote the ideal of a free culture and the
+further production of creative, cultural and scientific works, or to gain
+reputation or greater distribution for their Work in part through the use and
+efforts of others.
+
+For these and/or other purposes and motivations, and without any expectation
+of additional consideration or compensation, the person associating CC0 with a
+Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
+and Related Rights in the Work, voluntarily elects to apply CC0 to the Work
+and publicly distribute the Work under its terms, with knowledge of his or her
+Copyright and Related Rights in the Work and the meaning and intended legal
+effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not limited
+to, the following:
+
+ i. the right to reproduce, adapt, distribute, perform, display, communicate,
+ and translate a Work;
+
+ ii. moral rights retained by the original author(s) and/or performer(s);
+
+ iii. publicity and privacy rights pertaining to a person's image or likeness
+ depicted in a Work;
+
+ iv. rights protecting against unfair competition in regards to a Work,
+ subject to the limitations in paragraph 4(a), below;
+
+ v. rights protecting the extraction, dissemination, use and reuse of data in
+ a Work;
+
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+ European Parliament and of the Council of 11 March 1996 on the legal
+ protection of databases, and under any national implementation thereof,
+ including any amended or successor version of such directive); and
+
+ vii. other similar, equivalent or corresponding rights throughout the world
+ based on applicable law or treaty, and any national implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention of,
+applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
+unconditionally waives, abandons, and surrenders all of Affirmer's Copyright
+and Related Rights and associated claims and causes of action, whether now
+known or unknown (including existing as well as future claims and causes of
+action), in the Work (i) in all territories worldwide, (ii) for the maximum
+duration provided by applicable law or treaty (including future time
+extensions), (iii) in any current or future medium and for any number of
+copies, and (iv) for any purpose whatsoever, including without limitation
+commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes
+the Waiver for the benefit of each member of the public at large and to the
+detriment of Affirmer's heirs and successors, fully intending that such Waiver
+shall not be subject to revocation, rescission, cancellation, termination, or
+any other legal or equitable action to disrupt the quiet enjoyment of the Work
+by the public as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason be
+judged legally invalid or ineffective under applicable law, then the Waiver
+shall be preserved to the maximum extent permitted taking into account

+[https://github.com/mdn/data](https://github.com/mdn/data)
+
+Maintained by the [MDN team at Mozilla](https://wiki.mozilla.org/MDN).
+
+This repository contains general data for Web technologies.
+
+This data is used in MDN documentation, to build
+[information boxes](https://developer.mozilla.org/en-US/docs/Web/CSS/background)

+
+## Repository contents
+
+There's a top-level directory for each broad area covered: for example, "api",
+"css", "svg". Inside each of these directories is one or more
+JSON files containing the data.
+
+### api
+Contains data about Web APIs:
+* API inheritance (interface inheritance and mixin implementations)
+
+### css
+ Contains data about:
+* CSS at-rules
+* CSS properties
+* CSS selectors
+* CSS syntaxes
+* CSS types
+* CSS units
+
+Read more about [CSS data](https://github.com/mdn/data/blob/master/css/readme.md) and the format of the files.
+
+
+### l10n
+The l10n folder contains localization strings that are used in the various
+json files throughout this repository.

+# nth-check [](https://travis-ci.org/fb55/nth-check)
+
+Parses and compiles CSS nth-checks to highly optimized functions.
+
+### About
+
+This module can be used to parse & compile nth-checks, as they are found in CSS 3's `nth-child()` and `nth-last-of-type()`.
+
+`nth-check` focusses on speed, providing optimized functions for different kinds of nth-child formulas, while still following the [spec](http://www.w3.org/TR/css3-selectors/#nth-child-pseudo).
+
+### API
+
+```js
+import nthCheck, { parse, compile } from "nth-check";
+```
+
+##### `nthCheck(formula)`
+
+Parses and compiles a formula to a highly optimized function. Combination of `parse` and `compile`.
+
+If the formula doesn't match any elements, it returns [`boolbase`](https://github.com/fb55/boolbase)'s `falseFunc`. Otherwise, a function accepting an _index_ is returned, which returns whether or not the passed _index_ matches the formula.
+
+**Note**: The nth-rule starts counting at `1`, the returned function at `0`.
+
+**Example:**
+
+```js
+const check = nthCheck("2n+3");
+
+check(0); // `false`
+check(1); // `false`
+check(2); // `true`
+check(3); // `false`
+check(4); // `true`
+check(5); // `false`
+check(6); // `true`
+```
+
+##### `parse(formula)`
+
+Parses the expression, throws an `Error` if it fails. Otherwise, returns an array containing the integer step size and the integer offset of the nth rule.
+
+**Example:**
+
+```js
+parse("2n+3"); // [2, 3]
+```
+
+##### `compile([a, b])`
+
+Takes an array with two elements (as returned by `.parse`) and returns a highly optimized function.
+
+**Example:**
+
+```js
+const check = compile([2, 3]);
+
+check(0); // `false`
+check(1); // `false`
+check(2); // `true`
+check(3); // `false`
+check(4); // `true`
+check(5); // `false`
+check(6); // `true`
+```

+## Stable
+
+A stable array sort, because `Array#sort()` is not guaranteed stable.
+
+MIT licensed.
+
+[](http://travis-ci.org/Two-Screen/stable)
+
+[](http://ci.testling.com/Two-Screen/stable)
+
+#### From npm
+
+Install with:
+
+```sh
+npm install stable
+```
+
+Then use it in Node.js or some other CommonJS environment as:
+
+```js
+const stable = require('stable')
+```
+
+#### From the browser
+
+Include [`stable.js`] or the minified version [`stable.min.js`]
+in your page, then call `stable()`.
+
+ [`stable.js`]: https://raw.github.com/Two-Screen/stable/master/stable.js
+ [`stable.min.js`]: https://raw.github.com/Two-Screen/stable/master/stable.min.js
+
+#### Usage
+
+The default sort is, as with `Array#sort`, lexicographical:
+
+```js
+stable(['foo', 'bar', 'baz']) // => ['bar', 'baz', 'foo']
+stable([10, 1, 5]) // => [1, 10, 5]
+```
+
+Unlike `Array#sort`, the default sort is **NOT** in-place. To do an in-place
+sort, use `stable.inplace`, which otherwise works the same:
+
+```js
+const arr = [10, 1, 5]
+stable(arr) === arr // => false
+stable.inplace(arr) === arr // => true
+```
+
+A comparator function can be specified:
+
+```js
+// Regular sort() compatible comparator, that returns a number.
+// This demonstrates the default behavior.
+const lexCmp = (a, b) => String(a).localeCompare(b)
+stable(['foo', 'bar', 'baz'], lexCmp) // => ['bar', 'baz', 'foo']
+
+// Boolean comparator. Sorts `b` before `a` if true.
+// This demonstrates a simple way to sort numerically.
+const greaterThan = (a, b) => a > b
+stable([10, 1, 5], greaterThan) // => [1, 5, 10]
+```

+## SVGO [](https://npmjs.org/package/svgo) [](https://discord.gg/z8jX8NYxrE)
+
+**SVG O**ptimizer is a Node.js-based tool for optimizing SVG vector graphics files.
+
+## Why?
+
+SVG files, especially those exported from various editors, usually contain a lot of redundant and useless information. This can include editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting the SVG rendering result.
+
+## Installation
+
+```sh
+npm -g install svgo
+```
+
+or
+
+```sh
+yarn global add svgo
+```
+
+## CLI usage
+
+```sh
+svgo one.svg two.svg -o one.min.svg two.min.svg
+```
+
+Or use the `--folder`/`-f` flag to optimize a whole folder of SVG icons
+
+```sh
+svgo -f ./path/to/folder/with/svg/files -o ./path/to/folder/with/svg/output
+```
+
+See help for advanced usage
+
+```sh
+svgo --help
+```
+
+## Configuration
+
+Some options can be configured with CLI though it may be easier to have the configuration in a separate file.
+SVGO automatically loads configuration from `svgo.config.js` or module specified with `--config` flag.
+
+```js
+module.exports = {
+ multipass: true, // boolean. false by default
+ datauri: 'enc', // 'base64', 'enc' or 'unenc'. 'base64' by default
+ js2svg: {
+ indent: 2, // string with spaces or number of spaces. 4 by default
+ pretty: true, // boolean, false by default
+ }
+}
+```
+
+SVGO has a plugin-based architecture, so almost every optimization is a separate plugin.
+There is a set of [built-in plugins](#built-in-plugins). See how to configure them:
+
+```js
+module.exports = {
+ plugins: [
+ // enable a built-in plugin by name
+ 'builtinPluginName',
+ // or by expanded version
+ {
+ name: 'builtinPluginName'
+ },
+ // some plugins allow/require to pass options
+ {
+ name: 'builtinPluginName',
+ params: {
+ optionName: 'optionValue'
+ }
+ }
+ ]
+}
+```
+
+The default list is fully overridden if the `plugins` field is specified. To extend the default
+list use the `extendDefaultPlugins` utility:
+
+```js
+const { extendDefaultPlugins } = require('svgo');
+module.exports = {
+ plugins: extendDefaultPlugins([
+ {
+ name: 'builtinPluginName',
+ params: {
+ optionName: 'optionValue'
+ }
+ }
+ ])
+}
+```
+
+To disable one of the default plugins use the `active` field:
+
+```js
+const { extendDefaultPlugins } = require('svgo');
+module.exports = {
+ plugins: extendDefaultPlugins([
+ {
+ name: 'builtinPluginName',
+ active: false
+ }
+ ])
+}
+```
+
+See the list of the default plugins:
+
+```js
+module.exports = {
+ plugins: [
+ 'removeDoctype',
+ 'removeXMLProcInst',
+ 'removeComments',
+ 'removeMetadata',
+ 'removeEditorsNSData',
+ 'cleanupAttrs',
+ 'mergeStyles',
+ 'inlineStyles',
+ 'minifyStyles',
+ 'cleanupIDs',
+ 'removeUselessDefs',
+ 'cleanupNumericValues',
+ 'convertColors',
+ 'removeUnknownsAndDefaults',
+ 'removeNonInheritableGroupAttrs',
+ 'removeUselessStrokeAndFill',
+ 'removeViewBox',
+ 'cleanupEnableBackground',
+ 'removeHiddenElems',
+ 'removeEmptyText',
+ 'convertShapeToPath',
+ 'convertEllipseToCircle',
+ 'moveElemsAttrsToGroup',
+ 'moveGroupAttrsToElems',
+ 'collapseGroups',
+ 'convertPathData',
+ 'convertTransform',
+ 'removeEmptyAttrs',
+ 'removeEmptyContainers',
+ 'mergePaths',
+ 'removeUnusedNS',
+ 'sortDefsChildren',
+ 'removeTitle',
+ 'removeDesc'
+ ]
+}
+```
+
+It's also possible to specify a custom plugin:
+
+```js
+const anotherCustomPlugin = require('./another-custom-plugin.js')
+module.exports = {
+ plugins: [
+ {
+ name: 'customPluginName',
+ type: 'perItem', // 'perItem', 'perItemReverse' or 'full'
+ params: {
+ optionName: 'optionValue',
+ },
+ fn: (ast, params, info) => {}
+ },
+ anotherCustomPlugin
+ ]
+}
+```
+
+## API usage
+
+SVGO provides a few low level utilities. `extendDefaultPlugins` is described above.
+
+### optimize
+
+The core of SVGO is `optimize` function.
+
+```js
+const { optimize } = require('svgo');
+const result = optimize(svgString, {
+ // optional but recommended field
+ path: 'path-to.svg',
+ // all config fields are also available here
+ multipass: true
+})
+const optimizedSvgString = result.data
+```
+
+### loadConfig
+
+If you write a tool on top of SVGO you might need a way to load SVGO config.
+
+```js
+const { loadConfig } = require('svgo');
+const config = await loadConfig()
+
+// you can also specify a relative or absolute path and customize the current working directory
+const config = await loadConfig(configFile, cwd)
+```

+# ansi-styles [](https://travis-ci.org/chalk/ansi-styles)
+
+> [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+<img src="screenshot.svg" width="900">
+
+## Install
+
+```
+$ npm install ansi-styles
+```
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+// may be degraded to fit that color palette. This means terminals
+// that do not support 16 million colors will best-match the
+// original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#abcdef') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(Not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(Not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+The following color spaces from `color-convert` are supported:
+
+- `rgb`
+- `hex`
+- `keyword`
+- `hsl`
+- `hsv`
+- `hwb`
+- `ansi`
+- `ansi256`
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+## Highlights
+
+- Expressive API
+- Highly performant
+- Ability to nest styles
+- [256/Truecolor color support](#256-and-truecolor-color-support)
+- Auto-detects color support
+- Doesn't extend `String.prototype`
+- Clean and focused
+- Actively maintained
+- [Used by ~50,000 packages](https://www.npmjs.com/browse/depended/chalk) as of January 1, 2020
+
+## Install
+
+```console
+$ npm install chalk
+```
+
+## Usage
+
+```js
+const chalk = require('chalk');
+
+console.log(chalk.blue('Hello world!'));
+```
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+const chalk = require('chalk');
+const log = console.log;
+
+// Combine styled and normal strings
+log(chalk.blue('Hello') + ' World' + chalk.red('!'));
+
+// Compose multiple styles using the chainable API
+log(chalk.blue.bgRed.bold('Hello world!'));
+
+// Pass in multiple arguments
+log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
+
+// Nest styles
+log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
+
+// Nest styles of the same type even (color, underline, background)
+log(chalk.green(
+ 'I am a green line ' +
+ chalk.blue.underline.bold('with a blue substring') +
+ ' that becomes green again!'
+));
+
+// ES2015 template literal
+log(`
+CPU: ${chalk.red('90%')}
+RAM: ${chalk.green('40%')}
+DISK: ${chalk.yellow('70%')}
+`);
+
+// ES2015 tagged template literal
+log(chalk`
+CPU: {red ${cpu.totalPercent}%}
+RAM: {green ${ram.used / ram.total * 100}%}
+DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
+`);
+
+// Use RGB colors in terminal emulators that support it.
+log(chalk.keyword('orange')('Yay for orange colored text!'));
+log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
+log(chalk.hex('#DEADED').bold('Bold gray!'));
+```
+
+Easily define your own themes:
+
+```js
+const chalk = require('chalk');
+
+const error = chalk.bold.red;
+const warning = chalk.keyword('orange');
+
+console.log(error('Error!'));
+console.log(warning('Warning!'));
+```
+
+Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
+
+```js
+const name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> 'Hello Sindre'
+```
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.level
+
+Specifies the level of color support.
+
+Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.Instance({level: 0});
+```
+
+| Level | Description |
+| :---: | :--- |
+| `0` | All colors disabled |
+| `1` | Basic color support (16 colors) |
+| `2` | 256 color support |
+| `3` | Truecolor support (16 million colors) |
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
+
+### chalk.stderr and chalk.stderr.supportsColor
+
+`chalk.stderr` contains a separate instance configured with color support detected for `stderr` stream instead of `stdout`. Override rules from `chalk.supportsColor` apply to this too. `chalk.stderr.supportsColor` is exposed for convenience.
+
+## Styles
+
+### Modifiers
+
+- `reset` - Resets the current color chain.
+- `bold` - Make text bold.
+- `dim` - Emitting only a small amount of light.
+- `italic` - Make text italic. *(Not widely supported)*
+- `underline` - Make text underline. *(Not widely supported)*
+- `inverse`- Inverse background and foreground colors.
+- `hidden` - Prints the text, but makes it invisible.
+- `strikethrough` - Puts a horizontal line through the center of the text. *(Not widely supported)*
+- `visible`- Prints the text only when Chalk has a color level > 0. Can be useful for things that are purely cosmetic.
+

+
+## Tagged template literal
+
+Chalk can be used as a [tagged template literal](https://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
+
+```js
+const chalk = require('chalk');
+
+const miles = 18;
+const calculateFeet = miles => miles * 5280;
+
+console.log(chalk`
+ There are {bold 5280 feet} in a mile.
+ In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
+`);
+```
+
+Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
+
+Template styles are chained exactly like normal Chalk styles. The following three statements are equivalent:
+
+```js
+console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
+console.log(chalk.bold.rgb(10, 100, 200)`Hello!`);
+console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
+```
+
+Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
+
+All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
+
+## 256 and Truecolor color support
+
+Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
+
+Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
+
+Examples:
+
+- `chalk.hex('#DEADED').underline('Hello, world!')`
+- `chalk.keyword('orange')('Some orange text')`
+- `chalk.rgb(15, 100, 204).inverse('Hello!')`
+
+Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
+
+- `chalk.bgHex('#DEADED').underline('Hello, world!')`
+- `chalk.bgKeyword('orange')('Some orange text')`
+- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
+
+The following color models can be used:
+
+- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
+- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
+- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
+- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
+- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
+- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model) - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
+- [`ansi`](https://en.wikipedia.org/wiki/ANSI_escape_code#3/4_bit) - Example: `chalk.ansi(31).bgAnsi(93)('red on yellowBright')`
+- [`ansi256`](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) - Example: `chalk.bgAnsi256(194)('Honeydew, more or less')`
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [Windows Terminal](https://github.com/microsoft/terminal) instead of `cmd.exe`.
+
+## Origin story
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.

+# color-convert
+
+[](https://travis-ci.org/Qix-/color-convert)
+
+Color-convert is a color conversion library for JavaScript and node.
+It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hsl(140, 200, 100); // [96, 48, 59]
+convert.keyword.rgb('blue'); // [0, 0, 255]
+
+var rgbChannels = convert.rgb.channels; // 3
+var cmykChannels = convert.cmyk.channels; // 4
+var ansiChannels = convert.ansi16.channels; // 1
+```
+
+# Install
+
+```console
+$ npm install color-convert
+```
+
+# API
+
+Simply get the property of the _from_ and _to_ conversion that you're looking for.
+
+All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
+
+All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
+
+```js
+var convert = require('color-convert');
+
+// Hex to LAB
+convert.hex.lab('DEADBF'); // [ 76, 21, -2 ]
+convert.hex.lab.raw('DEADBF'); // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
+
+// RGB to CMYK
+convert.rgb.cmyk(167, 255, 4); // [ 35, 0, 98, 0 ]
+convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
+```
+
+### Arrays
+All functions that accept multiple arguments also support passing an array.
+
+Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hex(123, 45, 67); // '7B2D43'
+convert.rgb.hex([123, 45, 67]); // '7B2D43'
+```
+
+## Routing
+
+Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
+
+Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).
+
+# Contribute
+
+If there is a new model you would like to support, or want to add a direct conversion between two existing models, please send us a pull request.

+- use `.addHelpText()` to add text before or after the built-in help, for just current command or also for all subcommands ([#1296])
+- enhance Option class ([#1331])
+ - allow hiding options from help
+ - allow restricting option arguments to a list of choices
+ - allow setting how default value is shown in help
+- `.createOption()` to support subclassing of automatically created options (like `.createCommand()`) ([#1380])
+- refactor the code generating the help into a separate public Help class ([#1365])
+ - support sorting subcommands and options in help
+ - support specifying wrap width (columns)
+ - allow subclassing Help class
+ - allow configuring Help class without subclassing
+
+### Changed
+
+- *Breaking:* options are stored safely by default, not as properties on the command ([#1409])
+ - this especially affects accessing options on program, use `program.opts()`
+ - revert behaviour with `.storeOptionsAsProperties()`
+- *Breaking:* action handlers are passed options and command separately ([#1409])
+- deprecated callback parameter to `.help()` and `.outputHelp()` (removed from README) ([#1296])
+- *Breaking:* errors now displayed using `process.stderr.write()` instead of `console.error()`
+- deprecate `.on('--help')` (removed from README) ([#1296])
+- initialise the command description to empty string (previously undefined) ([#1365])
+- document and annotate deprecated routines ([#1349])
+
+### Fixed
+
+- wrapping bugs in help ([#1365])
+ - first line of command description was wrapping two characters early
+ - pad width calculation was not including help option and help command
+ - pad width calculation was including hidden options and commands
+- improve backwards compatibility for custom command event listeners ([#1403])
+
+### Deleted
+
+- *Breaking:* `.passCommandToAction()` ([#1409])
+ - no longer needed as action handler is passed options and command
+- *Breaking:* "extra arguments" parameter to action handler ([#1409])
+ - if being used to detect excess arguments, there is now an error available by setting `.allowExcessArguments(false)`
+
+### Migration Tips
+
+The biggest change is the parsed option values. Previously the options were stored by default as properties on the command object, and now the options are stored separately.
+
+If you wish to restore the old behaviour and get running quickly you can call `.storeOptionsAsProperties()`.
+To allow you to move to the new code patterns incrementally, the action handler will be passed the command _twice_,
+to match the new "options" and "command" parameters (see below).
+
+**program options**
+
+Use the `.opts()` method to access the options. This is available on any command but is used most with the program.
+
+```js
+program.option('-d, --debug');
+program.parse();
+// Old code before Commander 7
+if (program.debug) console.log(`Program name is ${program.name()}`);
+```
+
+```js
+// New code
+const options = program.opts();
+if (options.debug) console.log(`Program name is ${program.name()}`);
+```
+
+**action handler**
+
+The action handler gets passed a parameter for each command-argument you declared. Previously by default the next parameter was the command object with the options as properties. Now the next two parameters are instead the options and the command. If you
+only accessed the options there may be no code changes required.
+
+```js
+program
+ .command('compress <filename>')
+ .option('-t, --trace')
+ // Old code before Commander 7
+ .action((filename, cmd)) => {
+ if (cmd.trace) console.log(`Command name is ${cmd.name()}`);
+ });
+```
+
+```js
+ // New code
+ .action((filename, options, command)) => {
+ if (options.trace) console.log(`Command name is ${command.name()}`);
+ });
+```
+
+If you already set `.storeOptionsAsProperties(false)` you may still need to adjust your code.
+
+```js
+program
+ .command('compress <filename>')
+ .storeOptionsAsProperties(false)
+ .option('-t, --trace')
+ // Old code before Commander 7
+ .action((filename, command)) => {
+ if (command.opts().trace) console.log(`Command name is ${command.name()}`);
+ });
+```
+
+```js
+ // New code
+ .action((filename, options, command)) => {
+ if (command.opts().trace) console.log(`Command name is ${command.name()}`);
+ });
+```

+* removed private function `normalize` (the functionality has been integrated into `parseOptions`) ([#1145])
+* `parseExpectedArgs` is now private ([#1149])
+
+### Migration Tips
+
+If you use `.on('command:*')` or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.
+
+If you use `program.args` or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.
+
+If you use `.command('*')` to add a default command, you may be be able to switch to `isDefault:true` with a named command.
+
+If you want to continue combining short options with optional values as though they were boolean flags, set `combineFlagAndOptionalValue(false)`
+to expand `-fb` to `-f -b` rather than `-f b`.

+
+## Installation
+
+```bash
+npm install commander
+```
+
+## Declaring _program_ variable
+
+Commander exports a global object which is convenient for quick programs.
+This is used in the examples in this README for brevity.
+
+```js
+const { program } = require('commander');
+program.version('0.0.1');
+```
+
+For larger programs which may use commander in multiple ways, including unit testing, it is better to create a local Command object to use.
+
+```js
+const { Command } = require('commander');
+const program = new Command();
+program.version('0.0.1');
+```
+
+For named imports in ECMAScript modules, import from `commander/esm.mjs`.
+
+```js
+// index.mjs
+import { Command } from 'commander/esm.mjs';
+const program = new Command();
+```
+
+And in TypeScript:
+
+```ts
+// index.ts
+import { Command } from 'commander';
+const program = new Command();
+```
+
+
+## Options
+
+Options are defined with the `.option()` method, also serving as documentation for the options. Each option can have a short flag (single character) and a long name, separated by a comma or space or vertical bar ('|').
+
+The parsed options can be accessed by calling `.opts()` on a `Command` object, and are passed to the action handler. Multi-word options such as "--template-engine" are camel-cased, becoming `program.opts().templateEngine` etc.
+
+Multiple short flags may optionally be combined in a single argument following the dash: boolean flags, followed by a single option taking a value (possibly followed by the value).
+For example `-a -b -p 80` may be written as `-ab -p80` or even `-abp80`.
+
+You can use `--` to indicate the end of the options, and any remaining arguments will be used without being interpreted.
+
+By default options on the command line are not positional, and can be specified before or after other arguments.
+
+### Common option types, boolean and value
+
+The two most used option types are a boolean option, and an option which takes its value
+from the following argument (declared with angle brackets like `--expect <value>`). Both are `undefined` unless specified on command line.
+
+Example file: [options-common.js](./examples/options-common.js)
+
+```js
+program
+ .option('-d, --debug', 'output extra debugging')
+ .option('-s, --small', 'small pizza size')
+ .option('-p, --pizza-type <type>', 'flavour of pizza');
+
+program.parse(process.argv);
+
+const options = program.opts();
+if (options.debug) console.log(options);
+console.log('pizza details:');
+if (options.small) console.log('- small pizza size');
+if (options.pizzaType) console.log(`- ${options.pizzaType}`);
+```
+
+```bash
+$ pizza-options -d
+{ debug: true, small: undefined, pizzaType: undefined }
+pizza details:
+$ pizza-options -p
+error: option '-p, --pizza-type <type>' argument missing
+$ pizza-options -ds -p vegetarian
+{ debug: true, small: true, pizzaType: 'vegetarian' }
+pizza details:
+- small pizza size
+- vegetarian
+$ pizza-options --pizza-type=cheese
+pizza details:
+- cheese
+```
+
+`program.parse(arguments)` processes the arguments, leaving any args not consumed by the program options in the `program.args` array. The parameter is optional and defaults to `process.argv`.
+
+### Default option value
+
+You can specify a default value for an option which takes a value.
+
+Example file: [options-defaults.js](./examples/options-defaults.js)
+
+```js
+program
+ .option('-c, --cheese <type>', 'add the specified type of cheese', 'blue');
+
+program.parse();
+
+console.log(`cheese: ${program.opts().cheese}`);
+```
+
+```bash
+$ pizza-options
+cheese: blue
+$ pizza-options --cheese stilton
+cheese: stilton
+```
+
+### Other option types, negatable boolean and boolean|value
+
+You can define a boolean option long name with a leading `no-` to set the option value to false when used.
+Defined alone this also makes the option true by default.
+
+If you define `--foo` first, adding `--no-foo` does not change the default value from what it would
+otherwise be. You can specify a default boolean value for a boolean option and it can be overridden on command line.
+
+Example file: [options-negatable.js](./examples/options-negatable.js)
+
+```js
+program
+ .option('--no-sauce', 'Remove sauce')
+ .option('--cheese <flavour>', 'cheese flavour', 'mozzarella')
+ .option('--no-cheese', 'plain with no cheese')
+ .parse();
+
+const options = program.opts();
+const sauceStr = options.sauce ? 'sauce' : 'no sauce';
+const cheeseStr = (options.cheese === false) ? 'no cheese' : `${options.cheese} cheese`;
+console.log(`You ordered a pizza with ${sauceStr} and ${cheeseStr}`);
+```
+
+```bash
+$ pizza-options
+You ordered a pizza with sauce and mozzarella cheese
+$ pizza-options --sauce
+error: unknown option '--sauce'
+$ pizza-options --cheese=blue
+You ordered a pizza with sauce and blue cheese
+$ pizza-options --no-sauce --no-cheese
+You ordered a pizza with no sauce and no cheese
+```
+
+You can specify an option which may be used as a boolean option but may optionally take an option-argument
+(declared with square brackets like `--optional [value]`).
+
+Example file: [options-boolean-or-value.js](./examples/options-boolean-or-value.js)
+
+```js
+program
+ .option('-c, --cheese [type]', 'Add cheese with optional type');
+
+program.parse(process.argv);
+
+const options = program.opts();
+if (options.cheese === undefined) console.log('no cheese');
+else if (options.cheese === true) console.log('add cheese');
+else console.log(`add cheese type ${options.cheese}`);
+```
+
+```bash
+$ pizza-options
+no cheese
+$ pizza-options --cheese
+add cheese
+$ pizza-options --cheese mozzarella
+add cheese type mozzarella
+```
+
+For information about possible ambiguous cases, see [options taking varying arguments](./docs/options-taking-varying-arguments.md).
+
+### Required option
+
+You may specify a required (mandatory) option using `.requiredOption`. The option must have a value after parsing, usually specified on the command line, or perhaps from a default value (say from environment). The method is otherwise the same as `.option` in format, taking flags and description, and optional default value or custom processing.
+
+Example file: [options-required.js](./examples/options-required.js)
+
+```js
+program
+ .requiredOption('-c, --cheese <type>', 'pizza must have cheese');
+
+program.parse();
+```
+
+```bash
+$ pizza
+error: required option '-c, --cheese <type>' not specified
+```
+
+### Variadic option
+
+You may make an option variadic by appending `...` to the value placeholder when declaring the option. On the command line you
+can then specify multiple option-arguments, and the parsed option value will be an array. The extra arguments
+are read until the first argument starting with a dash. The special argument `--` stops option processing entirely. If a value
+is specified in the same argument as the option then no further values are read.
+
+Example file: [options-variadic.js](./examples/options-variadic.js)
+
+```js
+program
+ .option('-n, --number <numbers...>', 'specify numbers')
+ .option('-l, --letter [letters...]', 'specify letters');
+
+program.parse();
+
+console.log('Options: ', program.opts());
+console.log('Remaining arguments: ', program.args);
+```
+
+```bash
+$ collect -n 1 2 3 --letter a b c
+Options: { number: [ '1', '2', '3' ], letter: [ 'a', 'b', 'c' ] }
+Remaining arguments: []
+$ collect --letter=A -n80 operand
+Options: { number: [ '80' ], letter: [ 'A' ] }
+Remaining arguments: [ 'operand' ]
+$ collect --letter -n 1 -n 2 3 -- operand
+Options: { number: [ '1', '2', '3' ], letter: true }
+Remaining arguments: [ 'operand' ]
+```
+
+For information about possible ambiguous cases, see [options taking varying arguments](./docs/options-taking-varying-arguments.md).
+
+### Version option
+
+The optional `version` method adds handling for displaying the command version. The default option flags are `-V` and `--version`, and when present the command prints the version number and exits.
+
+```js
+program.version('0.0.1');
+```
+
+```bash
+$ ./examples/pizza -V
+0.0.1
+```
+
+You may change the flags and description by passing additional parameters to the `version` method, using
+the same syntax for flags as the `option` method.
+
+```js
+program.version('0.0.1', '-v, --vers', 'output the current version');
+```
+
+### More configuration
+
+You can add most options using the `.option()` method, but there are some additional features available
+by constructing an `Option` explicitly for less common cases.
+
+Example file: [options-extra.js](./examples/options-extra.js)
+
+```js
+program
+ .addOption(new Option('-s, --secret').hideHelp())
+ .addOption(new Option('-t, --timeout <delay>', 'timeout in seconds').default(60, 'one minute'))
+ .addOption(new Option('-d, --drink <size>', 'drink size').choices(['small', 'medium', 'large']));
+```
+
+```bash
+$ extra --help
+Usage: help [options]
+
+Options:
+ -t, --timeout <delay> timeout in seconds (default: one minute)
+ -d, --drink <size> drink cup size (choices: "small", "medium", "large")
+ -h, --help display help for command
+
+$ extra --drink huge
+error: option '-d, --drink <size>' argument 'huge' is invalid. Allowed choices are small, medium, large.
+```
+
+### Custom option processing
+
+You may specify a function to do custom processing of option-arguments. The callback function receives two parameters,
+the user specified option-argument and the previous value for the option. It returns the new value for the option.
+
+This allows you to coerce the option-argument to the desired type, or accumulate values, or do entirely custom processing.
+
+You can optionally specify the default/starting value for the option after the function parameter.
+
+Example file: [options-custom-processing.js](./examples/options-custom-processing.js)
+
+```js
+function myParseInt(value, dummyPrevious) {
+ // parseInt takes a string and a radix
+ const parsedValue = parseInt(value, 10);
+ if (isNaN(parsedValue)) {
+ throw new commander.InvalidOptionArgumentError('Not a number.');
+ }
+ return parsedValue;
+}
+
+function increaseVerbosity(dummyValue, previous) {
+ return previous + 1;
+}
+
+function collect(value, previous) {
+ return previous.concat([value]);
+}
+
+function commaSeparatedList(value, dummyPrevious) {
+ return value.split(',');
+}
+
+program
+ .option('-f, --float <number>', 'float argument', parseFloat)
+ .option('-i, --integer <number>', 'integer argument', myParseInt)
+ .option('-v, --verbose', 'verbosity that can be increased', increaseVerbosity, 0)
+ .option('-c, --collect <value>', 'repeatable value', collect, [])
+ .option('-l, --list <items>', 'comma separated list', commaSeparatedList)
+;
+
+program.parse();
+
+const options = program.opts();
+if (options.float !== undefined) console.log(`float: ${options.float}`);
+if (options.integer !== undefined) console.log(`integer: ${options.integer}`);
+if (options.verbose > 0) console.log(`verbosity: ${options.verbose}`);
+if (options.collect.length > 0) console.log(options.collect);
+if (options.list !== undefined) console.log(options.list);
+```
+
+```bash
+$ custom -f 1e2
+float: 100
+$ custom --integer 2
+integer: 2
+$ custom -v -v -v
+verbose: 3
+$ custom -c a -c b -c c
+[ 'a', 'b', 'c' ]
+$ custom --list x,y,z
+[ 'x', 'y', 'z' ]
+```
+
+## Commands
+
+You can specify (sub)commands using `.command()` or `.addCommand()`. There are two ways these can be implemented: using an action handler attached to the command, or as a stand-alone executable file (described in more detail later). The subcommands may be nested ([example](./examples/nestedCommands.js)).
+
+In the first parameter to `.command()` you specify the command name and any command-arguments. The arguments may be `<required>` or `[optional]`, and the last argument may also be `variadic...`.
+
+You can use `.addCommand()` to add an already configured subcommand to the program.
+
+For example:
+
+```js
+// Command implemented using action handler (description is supplied separately to `.command`)
+// Returns new command for configuring.
+program
+ .command('clone <source> [destination]')
+ .description('clone a repository into a newly created directory')
+ .action((source, destination) => {
+ console.log('clone command called');
+ });
+
+// Command implemented using stand-alone executable file (description is second parameter to `.command`)
+// Returns `this` for adding more commands.
+program
+ .command('start <service>', 'start named service')
+ .command('stop [service]', 'stop named service, or all if no name supplied');
+
+// Command prepared separately.
+// Returns `this` for adding more commands.
+program
+ .addCommand(build.makeBuildCommand());
+```
+
+Configuration options can be passed with the call to `.command()` and `.addCommand()`. Specifying `hidden: true` will
+remove the command from the generated help output. Specifying `isDefault: true` will run the subcommand if no other
+subcommand is specified ([example](./examples/defaultCommand.js)).
+
+### Specify the argument syntax
+
+You use `.arguments` to specify the expected command-arguments for the top-level command, and for subcommands they are usually
+included in the `.command` call. Angled brackets (e.g. `<required>`) indicate required command-arguments.
+Square brackets (e.g. `[optional]`) indicate optional command-arguments.
+You can optionally describe the arguments in the help by supplying a hash as second parameter to `.description()`.
+
+Example file: [arguments.js](./examples/arguments.js)
+
+```js
+program
+ .version('0.1.0')
+ .arguments('<username> [password]')
+ .description('test command', {
+ username: 'user to login',
+ password: 'password for user, if required'
+ })
+ .action((username, password) => {
+ console.log('username:', username);
+ console.log('environment:', password || 'no password given');
+ });
+```
+
+ The last argument of a command can be variadic, and only the last argument. To make an argument variadic you
+ append `...` to the argument name. For example:
+
+```js
+program
+ .version('0.1.0')
+ .command('rmdir <dirs...>')
+ .action(function (dirs) {
+ dirs.forEach((dir) => {
+ console.log('rmdir %s', dir);
+ });
+ });
+```
+
+The variadic argument is passed to the action handler as an array.
+
+### Action handler
+
+The action handler gets passed a parameter for each command-argument you declared, and two additional parameters
+which are the parsed options and the command object itself.
+
+Example file: [thank.js](./examples/thank.js)
+
+```js
+program
+ .arguments('<name>')
+ .option('-t, --title <honorific>', 'title to use before name')
+ .option('-d, --debug', 'display some debugging')
+ .action((name, options, command) => {
+ if (options.debug) {
+ console.error('Called %s with options %o', command.name(), options);
+ }
+ const title = options.title ? `${options.title} ` : '';
+ console.log(`Thank-you ${title}${name}`);
+ });
+```
+
+You may supply an `async` action handler, in which case you call `.parseAsync` rather than `.parse`.
+
+```js
+async function run() { /* code goes here */ }
+
+async function main() {
+ program
+ .command('run')
+ .action(run);
+ await program.parseAsync(process.argv);
+}
+```
+
+A command's options and arguments on the command line are validated when the command is used. Any unknown options or missing arguments will be reported as an error. You can suppress the unknown option checks with `.allowUnknownOption()`. By default it is not an error to
+pass more arguments than declared, but you can make this an error with `.allowExcessArguments(false)`.
+
+### Stand-alone executable (sub)commands
+
+When `.command()` is invoked with a description argument, this tells Commander that you're going to use stand-alone executables for subcommands.
+Commander will search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-subcommand`, like `pm-install`, `pm-search`.
+You can specify a custom name with the `executableFile` configuration option.
+
+You handle the options for an executable (sub)command in the executable, and don't declare them at the top-level.
+
+Example file: [pm](./examples/pm)
+
+```js
+program
+ .version('0.1.0')
+ .command('install [name]', 'install one or more packages')
+ .command('search [query]', 'search with optional query')
+ .command('update', 'update installed packages', { executableFile: 'myUpdateSubCommand' })
+ .command('list', 'list packages installed', { isDefault: true });
+
+program.parse(process.argv);
+```
+
+If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
+
+## Automated help
+
+The help information is auto-generated based on the information commander already knows about your program. The default
+help option is `-h,--help`.
+
+Example file: [pizza](./examples/pizza)
+
+```bash
+$ node ./examples/pizza --help
+Usage: pizza [options]
+
+An application for pizza ordering
+
+Options:
+ -p, --peppers Add peppers
+ -c, --cheese <type> Add the specified type of cheese (default: "marble")
+ -C, --no-cheese You do not want any cheese
+ -h, --help display help for command
+```
+
+A `help` command is added by default if your command has subcommands. It can be used alone, or with a subcommand name to show
+further help for the subcommand. These are effectively the same if the `shell` program has implicit help:
+
+```bash
+shell help
+shell --help
+
+shell help spawn
+shell spawn --help
+```
+
+### Custom help
+
+You can add extra text to be displayed along with the built-in help.
+
+Example file: [custom-help](./examples/custom-help)
+
+```js
+program
+ .option('-f, --foo', 'enable some foo');
+
+program.addHelpText('after', `
+
+Example call:
+ $ custom-help --help`);
+```
+
+Yields the following help output:
+
+```Text
+Usage: custom-help [options]
+
+Options:
+ -f, --foo enable some foo
+ -h, --help display help for command
+
+Example call:
+ $ custom-help --help
+```
+
+The positions in order displayed are:
+
+- `beforeAll`: add to the program for a global banner or header
+- `before`: display extra information before built-in help
+- `after`: display extra information after built-in help
+- `afterAll`: add to the program for a global footer (epilog)
+
+The positions "beforeAll" and "afterAll" apply to the command and all its subcommands.
+
+The second parameter can be a string, or a function returning a string. The function is passed a context object for your convenience. The properties are:
+
+- error: a boolean for whether the help is being displayed due to a usage error
+- command: the Command which is displaying the help
+
+### Display help from code
+
+`.help()`: display help information and exit immediately. You can optionally pass `{ error: true }` to display on stderr and exit with an error status.
+
+`.outputHelp()`: output help information without exiting. You can optionally pass `{ error: true }` to display on stderr.
+
+`.helpInformation()`: get the built-in command help information as a string for processing or displaying yourself.
+
+### .usage and .name
+
+These allow you to customise the usage description in the first line of the help. The name is otherwise
+deduced from the (full) program arguments. Given:
+
+```js
+program
+ .name("my-command")
+ .usage("[global options] command")
+```
+
+The help will start with:
+
+```Text
+Usage: my-command [global options] command
+```
+
+### .helpOption(flags, description)
+
+By default every command has a help option. Override the default help flags and description. Pass false to disable the built-in help option.
+
+```js
+program
+ .helpOption('-e, --HELP', 'read more information');
+```
+
+### .addHelpCommand()
+
+A help command is added by default if your command has subcommands. You can explicitly turn on or off the implicit help command with `.addHelpCommand()` and `.addHelpCommand(false)`.
+
+You can both turn on and customise the help command by supplying the name and description:
+
+```js
+program.addHelpCommand('assist [command]', 'show assistance');
+```
+
+### More configuration
+
+The built-in help is formatted using the Help class.
+You can configure the Help behaviour by modifying data properties and methods using `.configureHelp()`, or by subclassing using `.createHelp()` if you prefer.
+
+The data properties are:
+
+- `helpWidth`: specify the wrap width, useful for unit tests
+- `sortSubcommands`: sort the subcommands alphabetically
+- `sortOptions`: sort the options alphabetically
+
+There are methods getting the visible lists of arguments, options, and subcommands. There are methods for formatting the items in the lists, with each item having a _term_ and _description_. Take a look at `.formatHelp()` to see how they are used.
+
+Example file: [configure-help.js](./examples/configure-help.js)
+
+```
+program.configureHelp({
+ sortSubcommands: true,
+ subcommandTerm: (cmd) => cmd.name() // Just show the name, instead of short usage.
+});
+```
+
+## Custom event listeners
+
+You can execute custom actions by listening to command and option events.
+
+```js
+program.on('option:verbose', function () {
+ process.env.VERBOSE = this.opts().verbose;
+});
+
+program.on('command:*', function (operands) {
+ console.error(`error: unknown command '${operands[0]}'`);
+ const availableCommands = program.commands.map(cmd => cmd.name());
+ mySuggestBestMatch(operands[0], availableCommands);
+ process.exitCode = 1;
+});
+```
+
+## Bits and pieces
+
+### .parse() and .parseAsync()
+
+The first argument to `.parse` is the array of strings to parse. You may omit the parameter to implicitly use `process.argv`.
+
+If the arguments follow different conventions than node you can pass a `from` option in the second parameter:
+
+- 'node': default, `argv[0]` is the application and `argv[1]` is the script being run, with user parameters after that
+- 'electron': `argv[1]` varies depending on whether the electron application is packaged
+- 'user': all of the arguments from the user
+
+For example:
+
+```js
+program.parse(process.argv); // Explicit, node conventions
+program.parse(); // Implicit, and auto-detect electron
+program.parse(['-f', 'filename'], { from: 'user' });
+```
+
+### Parsing Configuration
+
+If the default parsing does not suit your needs, there are some behaviours to support other usage patterns.
+
+By default program options are recognised before and after subcommands. To only look for program options before subcommands, use `.enablePositionalOptions()`. This lets you use
+an option for a different purpose in subcommands.
+
+Example file: [positional-options.js](./examples/positional-options.js)
+
+With positional options, the `-b` is a program option in the first line and a subcommand option in the second line:
+
+```sh
+program -b subcommand
+program subcommand -b
+```
+
+By default options are recognised before and after command-arguments. To only process options that come
+before the command-arguments, use `.passThroughOptions()`. This lets you pass the arguments and following options through to another program
+without needing to use `--` to end the option processing.
+To use pass through options in a subcommand, the program needs to enable positional options.
+
+Example file: [pass-through-options.js](./examples/pass-through-options.js)
+
+With pass through options, the `--port=80` is a program option in the first line and passed through as a command-argument in the second line:
+
+```sh
+program --port=80 arg
+program arg --port=80
+```
+
+By default the option processing shows an error for an unknown option. To have an unknown option treated as an ordinary command-argument and continue looking for options, use `.allowUnknownOption()`. This lets you mix known and unknown options.
+
+By default the argument processing does not display an error for more command-arguments than expected.
+To display an error for excess arguments, use`.allowExcessArguments(false)`.
+
+### Legacy options as properties
+
+Before Commander 7, the option values were stored as properties on the command.
+This was convenient to code but the downside was possible clashes with
+existing properties of `Command`. You can revert to the old behaviour to run unmodified legacy code by using `.storeOptionsAsProperties()`.
+
+```js
+program
+ .storeOptionsAsProperties()
+ .option('-d, --debug')
+ .action((commandAndOptions) => {
+ if (commandAndOptions.debug) {
+ console.error(`Called ${commandAndOptions.name()}`);
+ }
+ });
+```
+
+### TypeScript
+
+If you use `ts-node` and stand-alone executable subcommands written as `.ts` files, you need to call your program through node to get the subcommands called correctly. e.g.
+
+```bash
+node -r ts-node/register pm.ts
+```
+
+### createCommand()
+
+This factory function creates a new command. It is exported and may be used instead of using `new`, like:
+
+```js
+const { createCommand } = require('commander');
+const program = createCommand();
+```
+
+`createCommand` is also a method of the Command object, and creates a new command rather than a subcommand. This gets used internally
+when creating subcommands using `.command()`, and you may override it to
+customise the new subcommand (example file [custom-command-class.js](./examples/custom-command-class.js)).
+
+### Node options such as `--harmony`
+
+You can enable `--harmony` option in two ways:
+
+- Use `#! /usr/bin/env node --harmony` in the subcommands scripts. (Note Windows does not support this pattern.)
+- Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning subcommand process.
+
+### Debugging stand-alone executable subcommands
+
+An executable subcommand is launched as a separate child process.
+
+If you are using the node inspector for [debugging](https://nodejs.org/en/docs/guides/debugging-getting-started/) executable subcommands using `node --inspect` et al,
+the inspector port is incremented by 1 for the spawned subcommand.
+
+If you are using VSCode to debug executable subcommands you need to set the `"autoAttachChildProcesses": true` flag in your launch.json configuration.
+
+### Override exit and output handling
+
+By default Commander calls `process.exit` when it detects errors, or after displaying the help or version. You can override
+this behaviour and optionally supply a callback. The default override throws a `CommanderError`.
+
+The override callback is passed a `CommanderError` with properties `exitCode` number, `code` string, and `message`. The default override behaviour is to throw the error, except for async handling of executable subcommand completion which carries on. The normal display of error messages or version or help
+is not affected by the override which is called after the display.
+
+```js
+program.exitOverride();
+
+try {
+ program.parse(process.argv);
+} catch (err) {
+ // custom processing...
+}
+```
+
+By default Commander is configured for a command-line application and writes to stdout and stderr.
+You can modify this behaviour for custom applications. In addition, you can modify the display of error messages.
+
+Example file: [configure-output.js](./examples/configure-output.js)
+
+
+```js
+function errorColor(str) {
+ // Add ANSI escape codes to display text in red.
+ return `\x1b[31m${str}\x1b[0m`;
+}
+
+program
+ .configureOutput({
+ // Visibly override write routines as example!
+ writeOut: (str) => process.stdout.write(`[OUT] ${str}`),
+ writeErr: (str) => process.stdout.write(`[ERR] ${str}`),
+ // Highlight errors in color.
+ outputError: (str, write) => write(errorColor(str))
+ });
+```
+
+### Additional documentation
+
+There is more information available about:
+
+- [deprecated](./docs/deprecated.md) features still supported for backwards compatibility
+- [options taking varying arguments](./docs/options-taking-varying-arguments.md)
+
+## Examples
+
+In a single command program, you might not need an action handler.
+
+Example file: [pizza](./examples/pizza)
+
+```js
+const { program } = require('commander');
+
+program
+ .description('An application for pizza ordering')
+ .option('-p, --peppers', 'Add peppers')
+ .option('-c, --cheese <type>', 'Add the specified type of cheese', 'marble')
+ .option('-C, --no-cheese', 'You do not want any cheese');
+
+program.parse();
+
+const options = program.opts();
+console.log('you ordered a pizza with:');
+if (options.peppers) console.log(' - peppers');
+const cheese = !options.cheese ? 'no' : options.cheese;
+console.log(' - %s cheese', cheese);
+```
+
+In a multi-command program, you will have action handlers for each command (or stand-alone executables for the commands).
+
+Example file: [deploy](./examples/deploy)
+
+```js
+const { Command } = require('commander');
+const program = new Command();
+
+program
+ .version('0.0.1')
+ .option('-c, --config <path>', 'set config path', './deploy.conf');
+
+program
+ .command('setup [env]')
+ .description('run setup commands for all envs')
+ .option('-s, --setup_mode <mode>', 'Which setup mode to use', 'normal')
+ .action((env, options) => {
+ env = env || 'all';
+ console.log('read config from %s', program.opts().config);
+ console.log('setup for %s env(s) with %s mode', env, options.setup_mode);
+ });
+
+program
+ .command('exec <script>')
+ .alias('ex')
+ .description('execute the given remote cmd')
+ .option('-e, --exec_mode <mode>', 'Which exec mode to use', 'fast')
+ .action((script, options) => {
+ console.log('read config from %s', program.opts().config);
+ console.log('exec "%s" using %s mode and config %s', script, options.exec_mode, program.opts().config);
+ }).addHelpText('after', `
+Examples:
+ $ deploy exec sequential
+ $ deploy exec async`
+ );
+
+program.parse(process.argv);
+```
+
+More samples can be found in the [examples](https://github.com/tj/commander.js/tree/master/examples) directory.
+
+## Support
+
+The current version of Commander is fully supported on Long Term Support versions of node, and requires at least node v10.
+(For older versions of node, use an older version of Commander. Commander version 2.x has the widest support.)
+
+The main forum for free and community support is the project [Issues](https://github.com/tj/commander.js/issues) on GitHub.

+# supports-color [](https://travis-ci.org/chalk/supports-color)
+
+> Detect whether a terminal supports color
+
+
+## Install
+
+```
+$ npm install supports-color
+```
+
+
+## Usage
+
+```js
+const supportsColor = require('supports-color');
+
+if (supportsColor.stdout) {
+ console.log('Terminal stdout supports color');
+}
+
+if (supportsColor.stdout.has256) {
+ console.log('Terminal stdout supports 256 colors');
+}
+
+if (supportsColor.stderr.has16m) {
+ console.log('Terminal stderr supports 16 million colors (truecolor)');
+}
+```
+
+
+## API
+
+Returns an `Object` with a `stdout` and `stderr` property for testing either streams. Each property is an `Object`, or `false` if color is not supported.
+
+The `stdout`/`stderr` objects specifies a level of support for color through a `.level` property and a corresponding flag:
+
+- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
+- `.level = 2` and `.has256 = true`: 256 color support
+- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
+
+
+## Info
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
