+
+``` javascript
+class LabeledCheckbox extends window.HTMLElement {
+  #internals;
+  constructor() {
+    super();
+    this.#internals = this.attachInternals();
+    // patch CustomStateSet
+    if (!this.#internals.states) {
+      this.#internals.states = new Set();
+    }
+    this.addEventListener('click', this._onClick.bind(this));
+  }
+  get checked() {
+    return this.#internals.states.has('checked');
+  }
+  set checked(flag) {
+    if (flag) {
+      this.#internals.states.add('checked');
+    } else {
+      this.#internals.states.delete('checked');
+    }
+  }
+  _onClick(event) {
+    this.checked = !this.checked;
+  }
+}

+
+Fast CSS Selectors API Engine
+
+![](https://img.shields.io/npm/v/nwsapi.svg?colorB=orange&style=flat) ![](https://img.shields.io/github/tag/dperini/nwsapi.svg?style=flat) ![](https://img.shields.io/npm/dw/nwsapi.svg?style=flat) ![](https://img.shields.io/github/issues/dperini/nwsapi.svg?style=flat)
+
+NWSAPI is the development progress of [NWMATCHER](https://github.com/dperini/nwmatcher) aiming at [Selectors Level 4](https://www.w3.org/TR/selectors-4/) conformance. It has been completely reworked to be easily extended and maintained. It is a right-to-left selector parser and compiler written in pure Javascript with no external dependencies. It was initially thought as a cross browser library to improve event delegation and web page scraping in various frameworks but it has become a popular replacement of the native CSS selection and matching functionality in newer browsers and headless environments.
+
+It uses [regular expressions](https://en.wikipedia.org/wiki/Regular_expression) to parse CSS selector strings and [metaprogramming](https://en.wikipedia.org/wiki/Metaprogramming) to transforms these selector strings into Javascript function resolvers. This process is executed only once for each selector string allowing memoization of the function resolvers and achieving unmatched performances.
+
+## Installation
+
+To include NWSAPI in a standard web page:
+
+```html
+<script type="text/javascript" src="nwsapi.js"></script>
+```
+
+To include NWSAPI in a standard web page and automatically replace the native QSA:
+
+```html
+<script type="text/javascript" src="nwsapi.js" onload="NW.Dom.install()"></script>
+```
+
+To use NWSAPI with Node.js:
+
+```
+$ npm install nwsapi
+```
+
+NWSAPI currently supports browsers (as a global, `NW.Dom`) and headless environments (as a CommonJS module).
+
+
+## Supported Selectors
+
+Here is a list of all the CSS2/CSS3/CSS4 [Supported selectors](https://github.com/dperini/nwsapi/wiki/CSS-supported-selectors).
+
+
+## Features and Compliance
+
+You can read more about NWSAPI [features and compliance](https://github.com/dperini/nwsapi/wiki/Features-and-compliance) on the wiki.
+
+
+## API
+
+### DOM Selection
+
+#### `ancestor( selector, context, callback )`
+
+Returns a reference to the nearest ancestor element matching `selector`, starting at `context`. Returns `null` if no element is found. If `callback` is provided, it is invoked for the matched element.
+
+#### `first( selector, context, callback )`
+
+Returns a reference to the first element matching `selector`, starting at `context`. Returns `null` if no element matches. If `callback` is provided, it is invoked for the matched element.
+
+#### `match( selector, element, callback )`
+
+Returns `true` if `element` matches `selector`, starting at `context`; returns `false` otherwise. If `callback` is provided, it is invoked for the matched element.
+
+#### `select( selector, context, callback )`
+
+Returns an array of all the elements matching `selector`, starting at `context`; returns empty `Array` otherwise. If `callback` is provided, it is invoked for each matching element.
+
+
+### DOM Helpers
+
+#### `byId( id, from )`
+
+Returns a reference to the first element with ID `id`, optionally filtered to descendants of the element `from`.
+
+#### `byTag( tag, from )`
+
+Returns an array of elements having the specified tag name `tag`, optionally filtered to descendants of the element `from`.
+
+#### `byClass( class, from )`
+
+Returns an array of elements having the specified class name `class`, optionally filtered to descendants of the element `from`.
+
+
+### Engine Configuration
+
+#### `configure( options )`
+
+The following is the list of currently available configuration options, their default values and descriptions, they are boolean flags that can be set to `true` or `false`:
+
+* `IDS_DUPES`: true  - true to allow using multiple elements having the same id, false to disallow
+* `LIVECACHE`: true  - true for caching both results and resolvers, false for caching only resolvers
+* `MIXEDCASE`: true  - true to match tag names case insensitive, false to match using case sensitive
+* `LOGERRORS`: true  - true to print errors and warnings to the console, false to mute both of them
+
+
+### Examples on extending the basic functionalities
+
+#### `configure( { <configuration-flag>: [ true | false ] } )`
+
+Disable logging errors/warnings to console, disallow duplicate ids. Example:
+
+```js
+NW.Dom.configure( { LOGERRORS: false, IDS_DUPES: false } );
+```
+NOTE: NW.Dom.configure() without parameters return the current configuration.
+
+#### `registerCombinator( symbol, resolver )`
+
+Registers a new symbol and its matching resolver in the combinators table. Example:
+
+```js
+NW.Dom.registerCombinator( '^', 'e.parentElement' );
+```
+
+#### `registerOperator( symbol, resolver )`
+
+Registers a new symbol and its matching resolver in the attribute operators table. Example:
+
+```js
+NW.Dom.registerOperator( '!=', { p1: '^', p2: '$', p3: 'false' } );
+```
+
+#### `registerSelector( name, rexp, func )`
+
+Registers a new selector, the matching RE and the resolver function, in the selectors table. Example:
+
+```js
+NW.Dom.registerSelector('Controls', /^\:(control)(.*)/i,
+  (function(global) {
+    return function(match, source, mode, callback) {
+      var status = true;
+      source = 'if(/^(button|input|select|textarea)/i.test(e.nodeName)){' + source + '}';
+      return { 'source': source, 'status': status };
+    };
+  })(this));
+```

+
+# Specificity
+
+`@bramus/specificity` is a package to calculate the specificity of CSS Selectors. It also includes some convenience functions to compare, sort, and filter an array of specificity values.
+
+Supports [Selectors Level 4](https://www.w3.org/TR/selectors-4/), including those special cases `:is()`, `:where()`, `:not()`, etc.
+
+Demo: [https://codepen.io/bramus/pen/WNXyoYm](https://codepen.io/bramus/pen/WNXyoYm)
+
+## Installation
+
+```bash
+npm i @bramus/specificity
+```
+
+## Usage / Example
+
+At its core, `@bramus/specificity` exposes a `Specificity` class. Its static `calculate` method can be used to calculate the specificity of a given CSS [Selector List](https://www.w3.org/TR/selectors-4/#grouping) string.
+
+```js
+import Specificity from '@bramus/specificity';
+
+const specificities = Specificity.calculate('header:where(#top) nav li:nth-child(2n), #doormat');
+```
+
+Because `calculate` accepts a [Selector List](https://www.w3.org/TR/selectors-4/#grouping) — which can contain more than 1 [Selector](https://www.w3.org/TR/selectors-4/#selector) — it will always return an array, with each entry being a `Specificity` instance — one per found selector.
+
+```js
+const specificities = Specificity.calculate('header:where(#top) nav li:nth-child(2n), #doormat');
+specificities.map((s) => s.toString()); // ~> ["(0,1,3)","(1,0,0)"]
+```
+
+💡 If you know you’re passing only a single Selector into `calculate()`, you can use JavaScript’s built-in destructuring to keep your variable names clean.
+
+```js
+const [s] = Specificity.calculate('header:where(#top) nav li:nth-child(2n)');
+s.toString(); // ~> "(0,1,3)"
+```
+
+💡 Under the hood, `@bramus/specificity` uses [CSSTree](https://github.com/csstree/csstree) to do the parsing of strings to Selectors. As a result, the `calculate` method also accepts a [CSSTree AST](https://github.com/csstree/csstree/blob/master/docs/ast.md) of the types `Selector` and `SelectorList`.
+
+If you have a pre-parsed CSSTree AST of the type `Selector` you can pass it into `Specificity.calculateForAST()`. It [performs slightly better](#benchmark) than `Specificity.calculate()` as it needs to check fewer things. It differs from `Specificity.calculate()` in that it does not return an array of `Specificity` instances but only a single value.
+
+## The Return Format
+
+A calculated specificity is represented as an instance of the `Specificity` class. The `Specificity` class includes methods to get the specificity value in a certain format, along with some convenience methods to compare it against other instances.
+
+```js
+// 🚀 Thunderbirds are go!
+import Specificity from '@bramus/specificity';
+
+// ✨ Calculate specificity for each Selector in the given Selector List
+const specificities = Specificity.calculate('header:where(#top) nav li:nth-child(2n), #doormat');
+
+// 🚚 The values in the array are instances of the Specificity class
+const s = specificities[0]; // Instance of Specificity
+
+// 👀 Read the specificity value using one of its accessors
+s.value; // { a: 0, b: 1, c: 3 }
+s.a; // 0
+s.b; // 1
+s.c; // 3
+
+// 🛠 Convert the calculated value to various formats using one of the toXXX() instance methods
+s.toString(); // "(0,1,3)"
+s.toArray(); // [0, 1, 3]
+s.toObject(); // { a: 0, b: 1, c: 3 }
+
+// 💡 Extract the matched selector string
+s.selectorString(); // "header:where(#top) nav li:nth-child(2n)"
+
+// 🔀 Use one of its instance comparison methods to compare it to another Specificity instance
+s.isEqualTo(specificities[1]); // false
+s.isGreaterThan(specificities[1]); // false
+s.isLessThan(specificities[1]); // true
+
+// 💻 Don’t worry about JSON.stringify()
+JSON.stringify(s);
+// {
+//    "selector": 'header:where(#top) nav li:nth-child(2n)',
+//    "asObject": { "a": 0, "b": 1, "c": 3 },
+//    "asArray": [0, 1, 3],
+//    "asString": "(0,1,3)",
+// }
+```
+
+## Utility Functions (Static Methods)
+
+This package also exposes some utility functions to work with specificities. These utility functions are all exposed as static methods on the `Specificity` class.
+
+-   Comparing:
+
+    -   `Specificity.compare(s1, s2)`: Compares s1 to s2. Returns a value that can be:
+        -   `> 0` = Sort s2 before s1 _(i.e. s1 is more specific than s2)_
+        -   `0` = Keep original order of s1 and s2 _(i.e. s1 and s2 are equally specific)_
+        -   `< 0` = Sort s1 before s2 _(i.e. s1 is less specific than s2)_
+    -   `Specificity.equals(s1, s2)`: Returns `true` if s1 and s2 have the same specificity. If not, `false` is returned.
+    -   `Specificity.greaterThan(s1, s2)`: Returns `true` if s1 has a higher specificity than s2. If not, `false` is returned.
+    -   `Specificity.lessThan(s1, s2)`: Returns `true` if s1 has a lower specificity than s2. If not, `false` is returned.
+
+-   Sorting:
+
+    -   `Specificity.sortAsc(s1, s2, …, sN)`: Sorts the given specificities in ascending order _(low specificity to high specificity)_
+    -   `Specificity.sortDesc(s1, s2, …, sN)`: Sorts the given specificities in descending order _(high specificity to low specificity)_
+
+-   Filtering:
+    -   `Specificity.min(s1, s2, …, sN)`: Filters out the value with the lowest specificity
+    -   `Specificity.max(s1, s2, …, sN)`: Filters out the value with the highest specificity
+
+A specificity passed into any of these utility functions can be any of:
+
+-   An instance of the included `Specificity` class
+-   A simple Object such as `{'a': 1, 'b': 0, 'c': 2}`
+
+## Utility Functions (Standalone)
+
+All static methods the `Specificity` class exposes are also exported as standalone functions using [Subpath Exports](https://nodejs.org/api/packages.html#subpath-exports).
+
+If you're only interested in including some of these functions into your project you can import them from their Subpath. As a result, your bundle size will be reduced greatly _(except for including the standalone `calculate`, as it returns an array of `Specificity` instances that relies on the whole lot)_
+
+```js
+import { calculate, calculateForAST } from '@bramus/specificity/core';
+import { compare, equals, greaterThan, lessThan } from '@bramus/specificity/compare';
+import { min, max } from '@bramus/specificity/filter';
+import { sortAsc, sortDesc } from '@bramus/specificity/sort';
+```
+
+## Type Definitions
+
+Although `@bramus/specificity` is written in Vanilla JavaScript, it does include [Type Definitions](https://www.typescriptlang.org/docs/handbook/2/type-declarations.html) which are exposed via its `package.json`.
+
+## Binary/CLI
+
+`@bramus/specificity` exposes a binary named `specificity` to calculate the specificity of a given selector list on the CLI. For each selector that it finds, it'll print out the calculated specificity as a string on a new line.
+
+```bash
+$ specificity "header:where(#top) nav li:nth-child(2n), #doormat"
+(0,1,3)
+(1,0,0)
+```
+
+## Benchmark
+
+A benchmark is included, which you can invoke using `npm run benchmark`.
+
+Sample results (tested on a MacBook Air M3):
+
+```
+Specificity.calculate(string) x 420,682 ops/sec ±0.34% (98 runs sampled)
+Specificity.calculate(ast) - using SelectorList x 8,994,080 ops/sec ±0.25% (98 runs sampled)
+Specificity.calculate(ast) - using Selector x 11,054,856 ops/sec ±0.39% (91 runs sampled)
+Specificity.calculateForAST(ast) x 12,652,322 ops/sec ±0.35% (96 runs sampled)
+```
+

+
+`@bramus/specificity` is released under the MIT public license. See the enclosed `LICENSE` for details.
+
+## Acknowledgements
+
+The idea to create this package was sparked by [the wonderful Specificity Calculator created by Kilian Valkhof / Polypane](https://polypane.app/css-specificity-calculator/), a highly educational tool that not only calculates the specificity, but also explains which parts are responsible for it.
+
+The heavy lifting of doing the actual parsing of Selectors is done by [CSSTree](https://github.com/csstree/csstree).
