[Shiki](https://github.com/shikijs/shiki) is a beautiful syntax highlighter powered by the same language engine that many code editors use. This package allows you to use Shiki from PHP.

```php
\Spatie\ShikiPhp\Shiki::highlight(
    code: '<?php echo "Hello World"; ?>',
    language: 'php',
    theme: 'github-light',
);
```

This package also ships with the following extra languages, on top of the [100+ that Shiki supports](https://github.com/shikijs/shiki/tree/master/docs/languages.md) out of the box: 

- Antlers
- Blade

## Usage in Laravel and league/commonmark

Laravel users can easily use Shiki via our [spatie/laravel-markdown](https://github.com/spatie/laravel-markdown) package.

If you need a league/commonmark extension to highlight code, head over to [spatie/commonmark-shiki-highlighter](https://github.com/spatie/commonmark-shiki-highlighter).

We invest a lot of resources into creating [best in class open source packages](https://spatie.be/open-source). You can support us by [buying one of our paid products](https://spatie.be/open-source/support-us).

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on [our contact page](https://spatie.be/about-us). We publish all received postcards on [our virtual postcard wall](https://spatie.be/open-source/postcards).

## Installation

You can install the package via composer:

```bash
composer require spatie/shiki-php
```

In your project, you must have the JavaScript package [`shiki`](https://github.com/shikijs/shiki) installed, otherwise the `<pre>` element will not be present in the output. 

You can install it via npm

```bash
npm install shiki
```

... or Yarn.

```bash
yarn add shiki
```

Make sure you have installed Node 10 or higher.

## Usage

Here's an example where we are going to highlight some PHP code.

```php
use Spatie\ShikiPhp\Shiki;

Shiki::highlight(
    code: '<?php echo "Hello World"; ?>',
    language: 'php',
    theme: 'github-light',
);
```

The output is this chunk of HTML which will render beautifully in the browser:

```php
<pre class="shiki" style="background-color: #2e3440ff"><code><span class="line"><span style="color: #81A1C1">&lt;?</span><span style="color: #D8DEE9FF">php </span><span style="color: #81A1C1">echo</span><span style="color: #D8DEE9FF"> </span><span style="color: #ECEFF4">&quot;</span><span style="color: #A3BE8C">Hello World</span><span style="color: #ECEFF4">&quot;</span><span style="color: #81A1C1">;</span><span style="color: #D8DEE9FF"> </span><span style="color: #81A1C1">?&gt;</span></span></code></pre>
```

## Marking lines as highlighted, added, deleted or focus

Shiki-php allows you to mark certain lines as `highlighted`, `added`, `deleted` and `focus`. To do this, you can pass in the necessary lines to the `highlight` method:

```php
use Spatie\ShikiPhp\Shiki;

// Highlighting lines 1 and 4,5,6
Shiki::highlight(
    code: $code,
    language: 'php',
    highlightLines: [1, '4-6'],
);

// Marking line 1 as added
Shiki::highlight(
    code: $code,
    language: 'php',
    addLines: [1],
);

// Marking line 1 as deleted
Shiki::highlight(
    code: $code,
    language: 'php',
    deleteLines: [1],
);

// Marking line 1 as focus
Shiki::highlight(
    code: $code,
    language: 'php',
    focusLines: [1],
);
```

You can then target these classes in your own CSS to color these lines how you want.

## PHP 7.4 support

Shiki has a nice and easy syntax in combination with at least PHP 8.

It does support PHP 7.4, but does loose a little bit of it's nice syntax if using it with PHP7.4, as you need to follow the order of the variables.

```php
// As reference
highlight(
    string $code,
    ?string $language = 'php',
    ?string $theme = 'nord',
    ?array $highlightLines = [],
    ?array $addLines = [],
    ?array $deleteLines = [],
    ?array $focusLines = []
)

// Instead of PHP 8 syntax
Shiki::highlight(
    code: $code,
    language: 'php',
    deleteLines: [1],
);

// You need to follow PHP 7.4 syntax
Shiki::highlight(
    $code,
    'php',
    null,
    null,
    [1],
);
```

## Determining available languages

To get an array with [all languages that Shiki supports](https://github.com/shikijs/shiki/blob/master/docs/languages.md), call `getAvailableLanguages`

```php
$shiki = new \Spatie\ShikiPhp\Shiki();

$shiki->getAvailableLanguages(); // returns an array
$shiki->languageIsAvailable('php'); // returns true
$shiki->languageIsAvailable('non-existing-language'); // returns false
```

## Determining available themes

To get an array with [all themes that Shiki supports](https://github.com/shikijs/shiki/blob/master/docs/themes.md), call `getAvailableThemes`

```php
$shiki = new \Spatie\ShikiPhp\Shiki();

$shiki->getAvailableThemes(); // returns an array
$shiki->themeIsAvailable('github-light'); // returns true
$shiki->themeIsAvailable('non-existing-theme'); // returns false
```

### Using a custom theme

Shiki [supports](https://github.com/shikijs/shiki/blob/master/docs/themes.md) any [VSCode themes](https://code.visualstudio.com/docs/getstarted/themes).

You can load a theme simply by passing an absolute path as the theme parameter.

```php
use Spatie\ShikiPhp\Shiki;

Shiki::highlight(
    code: '<?php echo "Hello World"; ?>',
    language: 'php',
    theme: __DIR__ . '/your-path-to/themes/some-theme.json',
);
```

## Using Node Version Manager

Under the hood, this package runs a node command  to render the markdown. If you use NVM during development, 
then the package will be unlikely to find your version of node as it looks for the node executable in
`/usr/local/bin` and `/opt/homebrew/bin` - if this is the case, then you should create a symlink between
the node distributable in your NVM folder, to that of the `usr/local/bin`. Such a command might look like this:

```bash
sudo ln -s /home/some-user/.nvm/versions/node/v17.3.1/bin/node /usr/local/bin/node
```

Creating this symlink will allow the package to find your NPM executable. Please note, if you change
your NPM version you will have to update your symlinks accordingly.

## Testing

You can run all the tests with this command:

```bash
composer test
```
