### resolve(color, opt)
resolves CSS color
#### Parameters
- `color` **[string][133]** color value
- system colors are not supported
- `opt` **[object][135]?** options (optional, default `{}`)
- `opt.currentColor` **[string][133]?**
- color to use for `currentcolor` keyword
- if omitted, it will be treated as a missing color,
i.e. `rgb(none none none / none)`
- `opt.customProperty` **[object][135]?**
- custom properties
- pair of `--` prefixed property name as a key and it's value,
e.g.
```javascript
const opt = {
customProperty: {
'--some-color': '#008000',
'--some-length': '16px'
}
};
```
- and/or `callback` function to get the value of the custom property,
e.g.
```javascript
const node = document.getElementById('foo');
const opt = {
customProperty: {
callback: node.style.getPropertyValue
}
};
```
- `opt.dimension` **[object][135]?**
- dimension, e.g. for converting relative length to pixels
- pair of unit as a key and number in pixels as it's value,
e.g. suppose `1em === 12px`, `1rem === 16px` and `100vw === 1024px`, then
```javascript
const opt = {
dimension: {
em: 12,
rem: 16,
vw: 10.24
}
};
```
- and/or `callback` function to get the value as a number in pixels,
e.g.
```javascript
const opt = {
dimension: {
callback: unit => {
switch (unit) {
case 'em':
return 12;
case 'rem':
return 16;
case 'vw':
return 10.24;
default:
return;
}
}
}
};
```
- `opt.format` **[string][133]?**
- output format, one of below
- `computedValue` (default), [computed value][139] of the color
- `specifiedValue`, [specified value][140] of the color
- `hex`, hex color notation, i.e. `#rrggbb`
- `hexAlpha`, hex color notation with alpha channel, i.e. `#rrggbbaa`
Returns **[string][133]?** one of `rgba?()`, `#rrggbb(aa)?`, `color-name`, `color(color-space r g b / alpha)`, `color(color-space x y z / alpha)`, `(ok)?lab(l a b / alpha)`, `(ok)?lch(l c h / alpha)`, `'(empty-string)'`, `null`
- in `computedValue`, values are numbers, however `rgb()` values are integers
- in `specifiedValue`, returns `empty string` for unknown and/or invalid color
- in `hex`, returns `null` for `transparent`, and also returns `null` if any of `r`, `g`, `b`, `alpha` is not a number
- in `hexAlpha`, returns `#00000000` for `transparent`, however returns `null` if any of `r`, `g`, `b`, `alpha` is not a number

Implemented from : https://drafts.csswg.org/css-values-4/ on 2023-02-17
## Usage
Add [CSS calc] to your project:
```bash
npm install @csstools/css-calc @csstools/css-parser-algorithms @csstools/css-tokenizer --save-dev
```
### With string values :
```mjs
import { calc } from '@csstools/css-calc';
// '20'
console.log(calc('calc(10 * 2)'));
```
### With component values :
```mjs
import { stringify, tokenizer } from '@csstools/css-tokenizer';
import { parseCommaSeparatedListOfComponentValues } from '@csstools/css-parser-algorithms';
import { calcFromComponentValues } from '@csstools/css-calc';
const t = tokenizer({
css: 'calc(10 * 2)',
});
const tokens = [];
{
while (!t.endOfFile()) {
tokens.push(t.nextToken());
}
tokens.push(t.nextToken()); // EOF-token
}
const result = parseCommaSeparatedListOfComponentValues(tokens, {});
// filter or mutate the component values
const calcResult = calcFromComponentValues(result, { precision: 5, toCanonicalUnits: true });
// filter or mutate the component values even further
const calcResultStr = calcResult.map((componentValues) => {
return componentValues.map((x) => stringify(...x.tokens())).join('');
}).join(',');
// '20'
console.log(calcResultStr);
```
### Options
#### `precision` :
The default precision is fairly high.
It aims to be high enough to make rounding unnoticeable in the browser.
You can set it to a lower number to suit your needs.
```mjs
import { calc } from '@csstools/css-calc';
// '0.3'
console.log(calc('calc(1 / 3)', { precision: 1 }));
// '0.33'
console.log(calc('calc(1 / 3)', { precision: 2 }));
```
#### `globals` :
Pass global values as a map of key value pairs.
> Example : Relative color syntax (`lch(from pink calc(l / 2) c h)`) exposes color channel information as ident tokens.
> By passing globals for `l`, `c` and `h` it is possible to solve nested `calc()`'s.
```mjs
import { calc } from '@csstools/css-calc';
const globals = new Map([
['a', '10px'],
['b', '2rem'],
]);
// '20px'
console.log(calc('calc(a * 2)', { globals: globals }));
// '6rem'
console.log(calc('calc(b * 3)', { globals: globals }));
```
#### `toCanonicalUnits` :
By default this package will try to preserve units.
The heuristic to do this is very simplistic.
We take the first unit we encounter and try to convert other dimensions to that unit.
This better matches what users expect from a CSS dev tool.
If you want to have outputs that are closes to CSS serialized values you can pass `toCanonicalUnits: true`.
```mjs
import { calc } from '@csstools/css-calc';
// '20hz'
console.log(calc('calc(0.01khz + 10hz)', { toCanonicalUnits: true }));
// '20hz'
console.log(calc('calc(10hz + 0.01khz)', { toCanonicalUnits: true }));
// '0.02khz' !!!
console.log(calc('calc(0.01khz + 10hz)', { toCanonicalUnits: false }));
// '20hz'
console.log(calc('calc(10hz + 0.01khz)', { toCanonicalUnits: false }));

# 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);
* ```

# CSS Tokenizer
[<img alt="npm version" src="https://img.shields.io/npm/v/@csstools/css-tokenizer.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-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

/**
* Tokenize CSS following the {@link https://drafts.csswg.org/css-syntax/#tokenization | 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.
*
* @example
* Tokenize a string of CSS into an array of tokens:
* ```js
* import { tokenize } from '@csstools/css-tokenizer';
*
* const myCSS = `@media only screen and (min-width: 768rem) {
* .foo {
* content: 'Some content!' !important;
