Virtual syntax highlighting for virtual DOMs and non-HTML things, with language
|
||
auto-detection.
|
||
Perfect for [React][], [VDOM][], and others.
|
||
|
||
Lowlight is built to work with all syntaxes supported by [highlight.js][],
|
||
that’s [191 languages][names] (and all 94 themes).
|
||
|
||
Want to use [Prism][] instead?
|
||
Try [`refractor`][refractor]!

## Install
|
||
|
||
[npm][]:
|
||
|
||
```sh
|
||
npm install lowlight
|
||
```
|
||
|
||
[Usage in the browser »][browser]
|
||
|
||
## Use
|
||
|
||
Highlight:
|
||
|
||
```js
|
||
var low = require('lowlight')
|
||
var tree = low.highlight('js', '"use strict";').value
|
||
|
||
console.log(tree)
|
||
```
|
||
|
||
Yields:
|
||
|
||
```js
|
||
[
|
||
{
|
||
type: 'element',
|
||
tagName: 'span',
|
||
properties: {className: ['hljs-meta']},
|
||
children: [{type: 'text', value: '"use strict"'}]
|
||
},
|
||
{type: 'text', value: ';'}
|
||
]
|
||
```
|
||
|
||
Or, serialized with [rehype-stringify][]:
|
||
|
||
```js
|
||
var unified = require('unified')
|
||
var rehypeStringify = require('rehype-stringify')
|
||
|
||
var processor = unified().use(rehypeStringify)
|
||
var html = processor.stringify({type: 'root', children: tree}).toString()
|
||
|
||
console.log(html)
|
||
```
|
||
|
||
Yields:
|
||
|
||
```html
|
||
<span class="hljs-meta">"use strict"</span>;
|
||
```
|
||
|
||
> **Tip**: Use [`hast-to-hyperscript`][to-hyperscript] to transform to other
|
||
> virtual DOMs, or DIY.
|
||
|
||
## API
|
||
|
||
### `low.highlight(language, value[, options])`
|
||
|
||
Parse `value` (`string`) according to the [`language`][names] grammar.
|
||
|
||
###### `options`
|
||
|
||
* `prefix` (`string?`, default: `'hljs-'`) — Class prefix
|
||
|
||
###### Returns
|
||
|
||
[`Result`][result].
|
||
|
||
###### Example
|
||
|
||
```js
|
||
var low = require('lowlight')
|
||
|
||
console.log(low.highlight('css', 'em { color: red }'))
|
||
```
|
||
|
||
Yields:
|
||
|
||
```js
|
||
{relevance: 4, language: 'css', value: [Array]}
|
||
```
|
||
|
||
### `low.highlightAuto(value[, options])`
|
||
|
||
Parse `value` by guessing its grammar.
|
||
|
||
###### `options`
|
||
|
||
* `prefix` (`string?`, default: `'hljs-'`)
|
||
— Class prefix
|
||
* `subset` (`Array.<string>?` default: all registered languages)
|
||
— List of allowed languages
|
||
|
||
###### Returns
|
||
|
||
[`Result`][result], with a `secondBest` if found.
|
||
|
||
###### Example
|
||
|
||
```js
|
||
var low = require('lowlight')
|
||
|
||
console.log(low.highlightAuto('"hello, " + name + "!"'))
|
||
```
|
||
|
||
Yields:
|
||
|
||
```js
|
||
{
|
||
relevance: 3,
|
||
language: 'applescript',
|
||
value: [Array],
|
||
secondBest: {relevance: 3, language: 'basic', value: [Array]}
|
||
}
|
||
```
|
||
|
||
### `Result`
|
||
|
||
`Result` is a highlighting result object.
|
||
|
||
###### Properties
|
||
|
||
* `relevance` (`number`)
|
||
— How sure **low** is that the given code is in the found language
|
||
* `language` (`string`)
|
||
— The detected `language`
|
||
* `value` ([`Array.<Node>`][hast-node])
|
||
— Virtual nodes representing the highlighted given code
|
||
* `secondBest` ([`Result?`][result])
|
||
— Result of the second-best (based on `relevance`) match.
|
||
Only set by `highlightAuto`, but can still be `null`.
|
||
|
||
### `low.registerLanguage(name, syntax)`
|
||
|
||
Register a [syntax][] as `name` (`string`).
|
||
Useful in the browser or with custom grammars.
|
||
|
||
###### Example
|
||
|
||
```js
|
||
var low = require('lowlight/lib/core')
|
||
var xml = require('highlight.js/lib/languages/xml')
|
||
|
||
low.registerLanguage('xml', xml)
|
||
|
||
console.log(low.highlight('html', '<em>Emphasis</em>'))
|
||
```
|
||
|
||
Yields:
|
||
|
||
```js
|
||
{relevance: 2, language: 'html', value: [Array]}
|
||
```
|
||
|
||
### `low.registerAlias(name[, alias])`
|
||
|
||
Register a new `alias` for the `name` language.
|
||
|
||
###### Signatures
|
||
|
||
* `registerAlias(name, alias|list)`
|
||
* `registerAlias(aliases)`
|
||
|
||
###### Parameters
|
||
|
||
* `name` (`string`) — [Name][names] of a registered language
|
||
* `alias` (`string`) — New alias for the registered language
|
||
* `list` (`Array.<alias>`) — List of aliases
|
||
* `aliases` (`Object.<alias|list>`) — Map where each key is a `name` and each
|
||
value an `alias` or a `list`
|
||
|
||
###### Example
|
||
|
||
```js
|
||
var low = require('lowlight/lib/core')
|
||
var md = require('highlight.js/lib/languages/markdown')
|
||
|
||
low.registerLanguage('markdown', md)
|
||
|
||
// low.highlight('mdown', '<em>Emphasis</em>')
|
||
// ^ would throw: Error: Unknown language: `mdown` is not registered
|
||
|
||
low.registerAlias({markdown: ['mdown', 'mkdn', 'mdwn', 'ron']})
|
||
low.highlight('mdown', '<em>Emphasis</em>')
|
||
// ^ Works!
|
||
```
|
||
|
||
### `low.listLanguages()`
|
||
|
||
List all registered languages.
|
||
|
||
###### Returns
|
||
|
||
`Array.<string>`.
|
||
|
||
###### Example
|
||
|
||
```js
|
||
var low = require('lowlight/lib/core')
|
||
var md = require('highlight.js/lib/languages/markdown')
|
||
|
||
console.log(low.listLanguages()) // => []
|
||
|
||
low.registerLanguage('markdown', md)
|
||
|
||
console.log(low.listLanguages()) // => ['markdown']
|
||
```
|
||
|
||
## Browser
|
||
|
||
It is not suggested to use the pre-built files or requiring `lowlight` in the
|
||
browser as that would include 916kB (260kB GZipped) of code.
|
||
|
||
Instead, require `lowlight/lib/core`, and include only the used highlighters.
|
||
For example:
|
||
|
||
```js
|
||
var low = require('lowlight/lib/core')
|
||
var js = require('highlight.js/lib/languages/javascript')
|
||
|
||
low.registerLanguage('javascript', js)
|
||
|
||
low.highlight('js', '"use strict";')
|
||
// See `Usage` for the results.
|
||
```
|
||
|
||
…when using [browserify][] and minifying with [tinyify][] this results in 24kB
|
||
of code (9kB with GZip).
