# CSS Parser Algorithms
[<img alt="npm version" src="https://img.shields.io/npm/v/@csstools/css-parser-algorithms.svg" height="20">][npm-url]
[<img alt="Build Status" src="https://github.com/csstools/postcss-plugins/workflows/test/badge.svg" height="20">][cli-url]
[<img alt="Discord" src="https://shields.io/badge/Discord-5865F2?logo=discord&logoColor=white">][discord]
Implemented from : https://www.w3.org/TR/2021/CRD-css-syntax-3-20211224/
## API
[Read the API docs](./docs/css-parser-algorithms.md)
## Usage
Add [CSS Parser Algorithms] to your project:
```bash
npm install @csstools/css-parser-algorithms @csstools/css-tokenizer --save-dev
```
[CSS Parser Algorithms] only accepts tokenized CSS.
It must be used together with `@csstools/css-tokenizer`.
```js
import { tokenizer, TokenType } from '@csstools/css-tokenizer';
import { parseComponentValue } from '@csstools/css-parser-algorithms';
const myCSS = `@media only screen and (min-width: 768rem) {
.foo {
content: 'Some content!' !important;
}
}
`;
const t = tokenizer({
css: myCSS,
});
const tokens = [];
{
while (!t.endOfFile()) {
tokens.push(t.nextToken());
}
tokens.push(t.nextToken()); // EOF-token
}
const options = {
onParseError: ((err) => {
throw err;
}),
};
const result = parseComponentValue(tokens, options);
console.log(result);
```
### Available functions
- [`parseComponentValue`](https://www.w3.org/TR/css-syntax-3/#parse-component-value)
- [`parseListOfComponentValues`](https://www.w3.org/TR/css-syntax-3/#parse-list-of-component-values)
- [`parseCommaSeparatedListOfComponentValues`](https://www.w3.org/TR/css-syntax-3/#parse-comma-separated-list-of-component-values)
### Utilities
#### `gatherNodeAncestry`
The AST does not expose the entire ancestry of each node.
The walker methods do provide access to the current parent, but also not the entire ancestry.
To gather the entire ancestry for a a given sub tree of the AST you can use `gatherNodeAncestry`.
The result is a `Map` with the child nodes as keys and the parents as values.
This allows you to lookup any ancestor of any node.
```js
import { parseComponentValue } from '@csstools/css-parser-algorithms';
const result = parseComponentValue(tokens, options);
const ancestry = gatherNodeAncestry(result);
```
### Options
```ts
{
onParseError?: (error: ParseError) => void
}
```
#### `onParseError`
The parser algorithms are forgiving and won't stop when a parse error is encountered.
Parse errors also aren't tokens.
To receive parsing error information you can set a callback.
Parser errors will try to inform you about the point in the parsing logic the error happened.
This tells you the kind of error.
## Goals and non-goals
Things this package aims to be:
- specification compliant CSS parser
- a reliable low level package to be used in CSS sub-grammars
What it is not:
- opinionated
- fast
- small
- a replacement for PostCSS (PostCSS is fast and also an ecosystem)

/**
* Parse CSS following the {@link https://drafts.csswg.org/css-syntax/#parsing | CSS Syntax Level 3 specification}.
*
* @remarks
* The tokenizing and parsing tools provided by CSS Tools are designed to be low level and generic with strong ties to their respective specifications.
*
* Any analysis or mutation of CSS source code should be done with the least powerful tool that can accomplish the task.
* For many applications it is sufficient to work with tokens.
* For others you might need to use {@link https://github.com/csstools/postcss-plugins/tree/main/packages/css-parser-algorithms | @csstools/css-parser-algorithms} or a more specific parser.
*
* The implementation of the AST nodes is kept lightweight and simple.
* Do not expect magic methods, instead assume that arrays and class instances behave like any other JavaScript.
*
* @example
* Parse a string of CSS into a component value:
* ```js
* import { tokenize } from '@csstools/css-tokenizer';
* import { parseComponentValue } from '@csstools/css-parser-algorithms';
*
* const myCSS = `calc(1px * 2)`;
*
* const componentValue = parseComponentValue(tokenize({
* css: myCSS,
* }));
*
* console.log(componentValue);
* ```
*
* @example
* Use the right algorithm for the job.
*
* Algorithms that can parse larger structures (comma-separated lists, ...) can also parse smaller structures.
* However, the opposite is not true.
*
* If your context allows a list of component values, use {@link parseListOfComponentValues}:
* ```js
* import { tokenize } from '@csstools/css-tokenizer';
* import { parseListOfComponentValues } from '@csstools/css-parser-algorithms';
*
* parseListOfComponentValues(tokenize({ css: `10x 20px` }));
* ```
*
* If your context allows a comma-separated list of component values, use {@link parseCommaSeparatedListOfComponentValues}:
* ```js
* import { tokenize } from '@csstools/css-tokenizer';
* import { parseCommaSeparatedListOfComponentValues } from '@csstools/css-parser-algorithms';
*
* parseCommaSeparatedListOfComponentValues(tokenize({ css: `20deg, 50%, 30%` }));
* ```
*
* @example
* Use the stateful walkers to keep track of the context of a given component value.
*
* ```js
* import { tokenize } from '@csstools/css-tokenizer';
* import { parseComponentValue, isSimpleBlockNode } from '@csstools/css-parser-algorithms';
*
* const myCSS = `calc(1px * (5 / 2))`;
*
* const componentValue = parseComponentValue(tokenize({ css: myCSS }));
*
* let state = { inSimpleBlock: false };
* componentValue.walk((entry) => {
* if (isSimpleBlockNode(entry)) {
* entry.state.inSimpleBlock = true;
* return;
* }
*
* if (entry.state.inSimpleBlock) {
* console.log(entry.node.toString()); // `5`, ...
* }
* }, state);
* ```

[<img alt="Build Status" src="https://github.com/csstools/postcss-plugins/workflows/test/badge.svg" height="20">][cli-url]
[<img alt="Discord" src="https://shields.io/badge/Discord-5865F2?logo=discord&logoColor=white">][discord]
Implemented from : https://www.w3.org/TR/2021/CRD-css-syntax-3-20211224/
## API
[Read the API docs](./docs/css-tokenizer.md)
## Usage
Add [CSS Tokenizer] to your project:
```bash
npm install @csstools/css-tokenizer --save-dev
```
```js
import { tokenizer, TokenType } from '@csstools/css-tokenizer';
const myCSS = `@media only screen and (min-width: 768rem) {
.foo {
content: 'Some content!' !important;
}
}
`;
const t = tokenizer({
css: myCSS,
});
while (true) {
const token = t.nextToken();
if (token[0] === TokenType.EOF) {
break;
}
console.log(token);
}
```
Or use the `tokenize` helper function:
```js
import { tokenize } from '@csstools/css-tokenizer';
const myCSS = `@media only screen and (min-width: 768rem) {
.foo {
content: 'Some content!' !important;
}
}
`;
const tokens = tokenize({
css: myCSS,
});
console.log(tokens);
```
### Options
```ts
{
onParseError?: (error: ParseError) => void
}
```
#### `onParseError`
The tokenizer is forgiving and won't stop when a parse error is encountered.
To receive parsing error information you can set a callback.
```js
import { tokenizer, TokenType } from '@csstools/css-tokenizer';
const t = tokenizer({
css: '\\',
}, { onParseError: (err) => console.warn(err) });
while (true) {
const token = t.nextToken();
if (token[0] === TokenType.EOF) {
break;
}
}
```
Parser errors will try to inform you where in the tokenizer logic the error happened.
This tells you what kind of error occurred.
## Goals and non-goals
Things this package aims to be:
- specification compliant CSS tokenizer
- a reliable low level package to be used in CSS parsers
What it is not:
- opinionated
- fast
- small

# Media Query List Parser
[<img alt="npm version" src="https://img.shields.io/npm/v/@csstools/media-query-list-parser.svg" height="20">][npm-url]
[<img alt="Build Status" src="https://github.com/csstools/postcss-plugins/workflows/test/badge.svg" height="20">][cli-url]
[<img alt="Discord" src="https://shields.io/badge/Discord-5865F2?logo=discord&logoColor=white">][discord]
Implemented from : https://www.w3.org/TR/mediaqueries-5/
## Usage
Add [Media Query List Parser] to your project:
```bash
npm install @csstools/media-query-list-parser @csstools/css-parser-algorithms @csstools/css-tokenizer --save-dev
```
[Media Query List Parser] depends on our CSS tokenizer and parser algorithms.
It must be used together with `@csstools/css-tokenizer` and `@csstools/css-parser-algorithms`.
```ts
import { parse } from '@csstools/media-query-list-parser';
export function parseCustomMedia() {
const mediaQueryList = parse('screen and (min-width: 300px), (50px < height < 30vw)');
mediaQueryList.forEach((mediaQuery) => {
mediaQuery.walk((entry, index) => {
// Index of the current Node in `parent`.
console.log(index);
// Type of `parent`.
console.log(entry.parent.type);
// Type of `node`
{
// Sometimes nodes can be arrays.
if (Array.isArray(entry.node)) {
entry.node.forEach((item) => {
console.log(item.type);
});
}
if ('type' in entry.node) {
console.log(entry.node.type);
}
}
// stringified version of the current node.
console.log(entry.node.toString());
// Return `false` to stop the walker.
return false;
});
});
}

# Selector Specificity

## Usage
Add [Selector Specificity] to your project:
```bash
npm install @csstools/selector-specificity --save-dev
```
```js
import parser from 'postcss-selector-parser';
import { selectorSpecificity } from '@csstools/selector-specificity';
const selectorAST = parser().astSync('#foo:has(> .foo)');
const specificity = selectorSpecificity(selectorAST);
console.log(specificity.a); // 1
console.log(specificity.b); // 1
console.log(specificity.c); // 0
```
_`selectorSpecificity` takes a single selector, not a list of selectors (not : `a, b, c`).
To compare or otherwise manipulate lists of selectors you need to call `selectorSpecificity` on each part._
### Comparing
The package exports a utility function to compare two specificities.
```js
import { selectorSpecificity, compare } from '@csstools/selector-specificity';
const s1 = selectorSpecificity(ast1);
const s2 = selectorSpecificity(ast2);
compare(s1, s2); // -1 | 0 | 1
```
- if `s1 < s2` then `compare(s1, s2)` returns a negative number (`< 0`)
- if `s1 > s2` then `compare(s1, s2)` returns a positive number (`> 0`)
- if `s1 === s2` then `compare(s1, s2)` returns zero (`=== 0`)
## Prior Art
- [keeganstreet/specificity](https://github.com/keeganstreet/specificity)
- [bramus/specificity](https://github.com/bramus/specificity)
For CSSTools we always use `postcss-selector-parser` and want to calculate specificity from this AST.

# `@dual-bundle/import-meta-resolve`
A fork of [`import-meta-resolve`](https://github.com/wooorm/import-meta-resolve)
with commonjs + ESM support at the same time, AKA dual package.
It will rebase and try to release in order to sync with the upstream every day,
see [.github/workflows/rebase.yml](.github/workflows/rebase.yml) for details.
## Installation
```bash
# npm
npm install @dual-bundle/import-meta-resolve
# yarn
yarn add @dual-bundle/import-meta-resolve
```
***
# import-meta-resolve
[![Build][build-badge]][build]

## What is this?
This package is a ponyfill for [`import.meta.resolve`][native-resolve].
It supports everything you need to resolve files just like modern Node does:
import maps, export maps, loading CJS and ESM projects, all of that!
## When to use this?
As of Node.js 20.0, `import.meta.resolve` is still behind an experimental flag.
This package can be used to do what it does in Node 1620.
## Install
This package is [ESM only][esm].
In Node.js (version 16+), install with [npm][]:
```sh
npm install import-meta-resolve
```
## Use
```js
import {resolve} from 'import-meta-resolve'
// A file:
console.log(resolve('./index.js', import.meta.url))
//=> file:///Users/tilde/Projects/oss/import-meta-resolve/index.js
// A CJS package:
console.log(resolve('builtins', import.meta.url))
//=> file:///Users/tilde/Projects/oss/import-meta-resolve/node_modules/builtins/index.js
// A scoped CJS package:
console.log(resolve('@eslint/eslintrc', import.meta.url))
//=> file:///Users/tilde/Projects/oss/import-meta-resolve/node_modules/@eslint/eslintrc/lib/index.js
// A package with an export map:
console.log(resolve('micromark/lib/parse', import.meta.url))
//=> file:///Users/tilde/Projects/oss/import-meta-resolve/node_modules/micromark/lib/parse.js
// A node builtin:
console.log(resolve('fs', import.meta.url))
//=> node:fs
```
## API
This package exports the identifiers [`moduleResolve`][moduleresolve] and
[`resolve`][resolve].
There is no default export.
### `resolve(specifier, parent)`
Match `import.meta.resolve` except that `parent` is required (you can pass
`import.meta.url`).
###### Parameters
* `specifier` (`string`)
— the module specifier to resolve relative to parent
(`/example.js`, `./example.js`, `../example.js`, `some-package`, `fs`, etc)
* `parent` (`string`, example: `import.meta.url`)
— the absolute parent module URL to resolve from; you must pass
`import.meta.url` or something else
###### Returns
Full `file:`, `data:`, or `node:` URL (`string`) to the found thing
###### Throws
Throws an [`ErrnoException`][errnoexception].
### `moduleResolve(specifier, parent, conditions, preserveSymlinks)`
The [“Resolver Algorithm Specification”][algo] as detailed in the Node docs
(which is slightly lower-level than `resolve`).
###### Parameters
* `specifier` (`string`)
`/example.js`, `./example.js`, `../example.js`, `some-package`, `fs`, etc
* `parent` (`URL`, example: `import.meta.url`)
— full URL (to a file) that `specifier` is resolved relative from
* `conditions` (`Set<string>`, default: `new Set(['node', 'import'])`)
— conditions
* `preserveSymlinks` (`boolean`, default: `false`)
— keep symlinks instead of resolving them
###### Returns
A URL object (`URL`) to the found thing.
###### Throws
Throws an [`ErrnoException`][errnoexception].
### `ErrnoException`
One of many different errors that occur when resolving (TypeScript type).
###### Type
```ts
type ErrnoExceptionFields = Error & {
errnode?: number | undefined
code?: string | undefined
path?: string | undefined
syscall?: string | undefined
url?: string | undefined
}
```
The `code` field on errors is one of the following strings:
* `'ERR_INVALID_MODULE_SPECIFIER'`
— when `specifier` is invalid (example: `'#'`)
* `'ERR_INVALID_PACKAGE_CONFIG'`
— when a `package.json` is invalid (example: invalid JSON)
* `'ERR_INVALID_PACKAGE_TARGET'`
— when a `package.json` `exports` or `imports` is invalid (example: when it
does not start with `'./'`)
* `'ERR_MODULE_NOT_FOUND'`
— when `specifier` cannot be found in `parent` (example: `'some-missing-package'`)
* `'ERR_NETWORK_IMPORT_DISALLOWED'`
— thrown when trying to resolve a local file or builtin from a remote file
(`node:fs` relative to `'https://example.com'`)
* `'ERR_PACKAGE_IMPORT_NOT_DEFINED'`
— when a local import is not defined in an import map (example: `'#local'`
when not defined)
* `'ERR_PACKAGE_PATH_NOT_EXPORTED'`
— when an export is not defined in an export map (example: `'tape/index.js'`,
which is not in its export map)
* `'ERR_UNSUPPORTED_DIR_IMPORT'`
— when attempting to import a directory (example: `'./lib/'`)
* `'ERR_UNKNOWN_FILE_EXTENSION'`
— when somehow reading a file that has an unexpected extensions (`'./readme.md'`)
* `'ERR_INVALID_ARG_VALUE'`

## Algorithm
The algorithm for `resolve` matches how Node handles `import.meta.resolve`, with
a couple of differences.
The algorithm for `moduleResolve` matches the [Resolver Algorithm
Specification][algo] as detailed in the Node docs (which is sync and slightly
lower-level than `resolve`).
## Differences to Node
* `parent` defaulting to `import.meta.url` cannot be ponyfilled: you have to
explicitly pass it
* no support for loaders (that would mean implementing all of loaders)
* no support for CLI flags:
`--conditions`,
`--experimental-default-type`,
`--experimental-json-modules`,
`--experimental-network-imports`,
`--experimental-policy`,
`--experimental-wasm-modules`,
`--input-type`,
`--no-addons`,
`--preserve-symlinks`, nor
`--preserve-symlinks-main`
work
* no support for `WATCH_REPORT_DEPENDENCIES` env variable
* no attempt is made to add a suggestion based on how things used to work in
CJS before to not-found errors
* prototypal methods are not guarded: Node protects for example `String#slice`
or so from being tampered with, whereas this doesnt
## Types
This package is fully typed with [TypeScript][].
It exports the additional type [`ErrnoException`][errnoexception].
## Compatibility
This package is at least compatible with all maintained versions of Node.js.
As of now, that is Node.js 16 and later.

# @nodelib/fs.scandir
> List files and directories inside the specified directory.
## :bulb: Highlights
The package is aimed at obtaining information about entries in the directory.
* :moneybag: Returns useful information: `name`, `path`, `dirent` and `stats` (optional).
* :gear: On Node.js 10.10+ uses the mechanism without additional calls to determine the entry type. See [`old` and `modern` mode](#old-and-modern-mode).
* :link: Can safely work with broken symbolic links.
## Install
```console
npm install @nodelib/fs.scandir
```
## Usage
```ts
import * as fsScandir from '@nodelib/fs.scandir';
fsScandir.scandir('path', (error, stats) => { /* … */ });
```
## API
### .scandir(path, [optionsOrSettings], callback)
Returns an array of plain objects ([`Entry`](#entry)) with information about entry for provided path with standard callback-style.
```ts
fsScandir.scandir('path', (error, entries) => { /* … */ });
fsScandir.scandir('path', {}, (error, entries) => { /* … */ });
fsScandir.scandir('path', new fsScandir.Settings(), (error, entries) => { /* … */ });
```
### .scandirSync(path, [optionsOrSettings])
Returns an array of plain objects ([`Entry`](#entry)) with information about entry for provided path.
```ts
const entries = fsScandir.scandirSync('path');
const entries = fsScandir.scandirSync('path', {});
const entries = fsScandir.scandirSync(('path', new fsScandir.Settings());
```
#### path
* Required: `true`
* Type: `string | Buffer | URL`
A path to a file. If a URL is provided, it must use the `file:` protocol.
#### optionsOrSettings
* Required: `false`
* Type: `Options | Settings`
* Default: An instance of `Settings` class
An [`Options`](#options) object or an instance of [`Settings`](#settingsoptions) class.
> :book: When you pass a plain object, an instance of the `Settings` class will be created automatically. If you plan to call the method frequently, use a pre-created instance of the `Settings` class.
### Settings([options])
A class of full settings of the package.
```ts
const settings = new fsScandir.Settings({ followSymbolicLinks: false });
const entries = fsScandir.scandirSync('path', settings);
```
## Entry
* `name` — The name of the entry (`unknown.txt`).
* `path` — The path of the entry relative to call directory (`root/unknown.txt`).
* `dirent` — An instance of [`fs.Dirent`](./src/types/index.ts) class. On Node.js below 10.10 will be emulated by [`DirentFromStats`](./src/utils/fs.ts) class.
* `stats` (optional) — An instance of `fs.Stats` class.
For example, the `scandir` call for `tools` directory with one directory inside:
```ts
{
dirent: Dirent { name: 'typedoc', /* … */ },
name: 'typedoc',
path: 'tools/typedoc'
}
```
## Options
### stats
* Type: `boolean`
* Default: `false`
Adds an instance of `fs.Stats` class to the [`Entry`](#entry).
> :book: Always use `fs.readdir` without the `withFileTypes` option. ??TODO??
### followSymbolicLinks
* Type: `boolean`
* Default: `false`
Follow symbolic links or not. Call `fs.stat` on symbolic link if `true`.
### `throwErrorOnBrokenSymbolicLink`
* Type: `boolean`
* Default: `true`
Throw an error when symbolic link is broken if `true` or safely use `lstat` call if `false`.
### `pathSegmentSeparator`
* Type: `string`
* Default: `path.sep`
By default, this package uses the correct path separator for your OS (`\` on Windows, `/` on Unix-like systems). But you can set this option to any separator character(s) that you want to use instead.
### `fs`
* Type: [`FileSystemAdapter`](./src/adapters/fs.ts)
* Default: A default FS methods
By default, the built-in Node.js module (`fs`) is used to work with the file system. You can replace any method with your own.
```ts
interface FileSystemAdapter {
lstat?: typeof fs.lstat;
stat?: typeof fs.stat;
lstatSync?: typeof fs.lstatSync;
statSync?: typeof fs.statSync;
readdir?: typeof fs.readdir;
readdirSync?: typeof fs.readdirSync;
}
const settings = new fsScandir.Settings({
fs: { lstat: fakeLstat }
});
```
## `old` and `modern` mode
This package has two modes that are used depending on the environment and parameters of use.
### old
* Node.js below `10.10` or when the `stats` option is enabled
When working in the old mode, the directory is read first (`fs.readdir`), then the type of entries is determined (`fs.lstat` and/or `fs.stat` for symbolic links).
### modern
* Node.js 10.10+ and the `stats` option is disabled
In the modern mode, reading the directory (`fs.readdir` with the `withFileTypes` option) is combined with obtaining information about its entries. An additional call for symbolic links (`fs.stat`) is still present.
This mode makes fewer calls to the file system. It's faster.

# @nodelib/fs.stat
> Get the status of a file with some features.
## :bulb: Highlights
Wrapper around standard method `fs.lstat` and `fs.stat` with some features.
* :beginner: Normally follows symbolic link.
* :gear: Can safely work with broken symbolic link.
## Install
```console
npm install @nodelib/fs.stat
```
## Usage
```ts
import * as fsStat from '@nodelib/fs.stat';
fsStat.stat('path', (error, stats) => { /* … */ });
```
## API
### .stat(path, [optionsOrSettings], callback)
Returns an instance of `fs.Stats` class for provided path with standard callback-style.
```ts
fsStat.stat('path', (error, stats) => { /* … */ });
fsStat.stat('path', {}, (error, stats) => { /* … */ });
fsStat.stat('path', new fsStat.Settings(), (error, stats) => { /* … */ });
```
### .statSync(path, [optionsOrSettings])
Returns an instance of `fs.Stats` class for provided path.
```ts
const stats = fsStat.stat('path');
const stats = fsStat.stat('path', {});
const stats = fsStat.stat('path', new fsStat.Settings());
```
#### path
* Required: `true`
* Type: `string | Buffer | URL`
A path to a file. If a URL is provided, it must use the `file:` protocol.
#### optionsOrSettings
* Required: `false`
* Type: `Options | Settings`
* Default: An instance of `Settings` class
An [`Options`](#options) object or an instance of [`Settings`](#settings) class.
> :book: When you pass a plain object, an instance of the `Settings` class will be created automatically. If you plan to call the method frequently, use a pre-created instance of the `Settings` class.
### Settings([options])
A class of full settings of the package.
```ts
const settings = new fsStat.Settings({ followSymbolicLink: false });
const stats = fsStat.stat('path', settings);
```
## Options
### `followSymbolicLink`
* Type: `boolean`
* Default: `true`
Follow symbolic link or not. Call `fs.stat` on symbolic link if `true`.
### `markSymbolicLink`
* Type: `boolean`
* Default: `false`
Mark symbolic link by setting the return value of `isSymbolicLink` function to always `true` (even after `fs.stat`).
> :book: Can be used if you want to know what is hidden behind a symbolic link, but still continue to know that it is a symbolic link.
### `throwErrorOnBrokenSymbolicLink`
* Type: `boolean`
* Default: `true`
Throw an error when symbolic link is broken if `true` or safely return `lstat` call if `false`.
### `fs`
* Type: [`FileSystemAdapter`](./src/adapters/fs.ts)
* Default: A default FS methods
By default, the built-in Node.js module (`fs`) is used to work with the file system. You can replace any method with your own.
```ts
interface FileSystemAdapter {
lstat?: typeof fs.lstat;
stat?: typeof fs.stat;
lstatSync?: typeof fs.lstatSync;
statSync?: typeof fs.statSync;
}
const settings = new fsStat.Settings({
fs: { lstat: fakeLstat }
});
```
