# Wagtail Highlight.js

Wagtail Code Block is a syntax highlighter block for source code for the Wagtail CMS. It features real-time highlighting in the Wagtail editor, the front end, and support for [Highlight.js themes](https://highlightjs.org/demo).

It uses the [Highlight.js](https://highlightjs.org/) library both in Wagtail Admin and the website.

## Example Usage

First, add `wagtailcodeblock` to your `INSTALLED_APPS` in Django's settings. Here's a bare bones example:

```python
from wagtail.blocks import TextBlock
from wagtail.fields import StreamField
from wagtail.models import Page
from wagtail.admin.panels import FieldPanel

from wagtailcodeblock.blocks import CodeBlock


class HomePage(Page):
    body = StreamField([
        ("heading", TextBlock()),
        ("code", CodeBlock(label='Code')),
    ])

    content_panels = Page.content_panels + [
        FieldPanel("body"),
    ]
```

You can also force it to use a single language or set a default language by providing a language code which must be included in your `WAGTAIL_CODE_BLOCK_LANGUAGES` setting:

```python
bash_code = CodeBlock(label='Bash Code', language='bash')
any_code = CodeBlock(label='Any code', default_language='python')
```

## Installation & Setup

To install Wagtail Code Block run:

```bash
# Wagtail 4.0 and greater
pip install wagtailcodeblock

# Wagtail 3.x
pip install wagtailcodeblock==1.28.0.0

# Wagtail 2.x
pip install wagtailcodeblock==1.25.0.2
```

And add `wagtailcodeblock` to your `INSTALLED_APPS` setting:

```python
INSTALLED_APPS = [
    ...
    'wagtailcodeblock',
    ...
]
```

## Django Settings

### Line Numbers

Line numbers are enabled by default, but can be disabled in Django's settings:

```python
WAGTAIL_CODE_BLOCK_LINE_NUMBERS = False
```

### Copy to clipboard

Copy to clipboard is enabled by default, but can be disabled in Django's settings:

```python
WAGTAIL_CODE_BLOCK_COPY_TO_CLIPBOARD = False
```

### Themes

TODO: rewrite themes section
Wagtail Code Block defaults to the PrismJS "Coy" theme, which looks good with Wagtail's CMS editor design. You can choose a different theme by configuring `WAGTAIL_CODE_BLOCK_THEME` in your Django settings. PrismJS provides several themes:

* **None**: <a href="http://prismjs.com/index.html?theme=prism" target="_blank">Default</a>
* **'coy'**: <a href="http://prismjs.com/index.html?theme=prism-coy" target="_blank">Coy</a>
* **'dark'**: <a href="http://prismjs.com/index.html?theme=prism-dark" target="_blank">Dark</a>
* **'funky'**: <a href="http://prismjs.com/index.html?theme=prism-funky" target="_blank">Funky</a>
* **'okaidia'**: <a href="http://prismjs.com/index.html?theme=prism-okaidia" target="_blank">Okaidia</a>
* **'solarizedlight'**: <a href="http://prismjs.com/index.html?theme=prism-solarizedlight" target="_blank">Solarized Light</a>
* **'twilight'**: <a href="http://prismjs.com/index.html?theme=prism-twilight" target="_blank">Twilight</a>

For example, in you want to use the Solarized Light theme: `WAGTAIL_CODE_BLOCK_THEME = 'solarizedlight'`
If you want to use the Default theme: `WAGTAIL_CODE_BLOCK_THEME = None`

### Languages Available

You can customize the languages available by configuring `WAGTAIL_CODE_BLOCK_LANGUAGES` in your Django settings. By default, it will be set with these languages, since most users are in the Python web development community:

```python
WAGTAIL_CODE_BLOCK_LANGUAGES = (
    ('bash', 'Bash/Shell'),
    ('css', 'CSS'),
    ('diff', 'diff'),
    ('html', 'HTML'),
    ('javascript', 'Javascript'),
    ('json', 'JSON'),
    ('python', 'Python'),
    ('scss', 'SCSS'),
    ('yaml', 'YAML'),
)
```

Each language in this setting is a tuple of the PrismJS code and a descriptive label. If you want use all available languages, here is a list:

```python
