⚙️ Usage

Kirby Blocks Field

This plugin overwrites the Kirby's native code block, the output will be highlighted automatically.

blocks:
  type: blocks
  fieldsets:
    - code

By default, the code block uses the default theme. A theme selector is provided for applying different themes to individual blocks. You can also customize the available languages and themes.

KirbyText

Embed syntax-highlighted code directly in KirbyText fields:

```php
echo "Hello, world!";
```

Or use the plugin's custom KirbyTag with support for base64-encoded content:

(code: ZWNobyAiSGVsbG8sIHdvcmxkISI7 lang: php theme: github-light)

By default, the code tag applies the default theme. However, you can use the theme attribute to specify a different theme for individual code blocks.

🔧 Configuration

All options goes into your config.php file:

Default Theme

Set the default theme:

'bogdancondorachi.code-highlighter' => [
  'theme' => 'github-dark-default',
],

Check out the supported themes

Default Language

Set the default language:

'bogdancondorachi.code-highlighter' => [
  'language' => 'text',
],

Check out the supported languages

Light/Dark Dual Themes

If you use light/dark mode on your website, you can set a default theme for each individual mode:

'bogdancondorachi.code-highlighter' => [
  'themes' => [
    'light' => 'github-light',
    'dark' => 'github-dark'
  ]
],

In this case, you'll need to add one of the CSS snippet's to make it reactive to your site's theme:

Query-based Dark Mode

@media (prefers-color-scheme: light) {
  .phiki,
  .phiki span {
    color: var(--phiki-light);
    background-color: var(--phiki-light-bg);
  }
}

@media (prefers-color-scheme: dark) {
  .phiki,
  .phiki span {
    color: var(--phiki-dark);
    background-color: var(--phiki-dark-bg);
  }
}

Class-based Dark Mode

html.light .phiki,
html.light .phiki span {
  color: var(--phiki-light);
  background-color: var(--phiki-light-bg);
}

html.dark .phiki,
html.dark .phiki span {
  color: var(--phiki-dark);
  background-color: var(--phiki-dark-bg);
}

Line Numbering

Enable line numbers in your rendered code blocks:

'bogdancondorachi.code-highlighter' => [
  'gutter' => true,
],

Customize Languages and Themes Selection

Customize the languages and themes options available in Kirby’s code block:

'bogdancondorachi.code-highlighter' => [
  'block.languages' => [
    'css' => 'CSS',
    'php' => 'PHP',
    'yml' => 'Yaml',
  ],
  'block.themes' => [
    'github-dark' => 'GitHub Dark',
    'github-light' => 'GitHub Light',
    'vitesse-dark' => 'Vitesse Dark',
  ],
],

Front-end Block Styling

Further customize the block style to match your site's design. Here's an example:

.phiki {
  margin: 2rem 0;
  padding: 1rem;
  font-size: 0.875rem;
  line-height: 1.5rem;
  overflow: auto;
  border-radius: 0.25rem;
  box-shadow:
    0 1px 3px 0 rgba(0, 0, 0, 0.1),
    0 1px 2px 0 rgba(0, 0, 0, 0.06);
}

.phiki .line-number {
  margin-right: 1rem;
  text-align: right;
}
