Wagtail Highlight.js 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.
It uses the Highlight.js library both in Wagtail Admin and the website.
First, add wagtail_hljs to your INSTALLED_APPS in Django's settings. Here's a bare bones example:
from wagtail.blocks import TextBlock
from wagtail.fields import StreamField
from wagtail.models import Page
from wagtail.admin.panels import FieldPanel
from wagtail_hljs.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_HLJS_LANGUAGES setting:
bash_code = CodeBlock(label='Bash Code', language='bash')
any_code = CodeBlock(label='Any code', default_language='python')To install Wagtail Highlight.js run:
# Wagtail 4.0 and greater
pip install wagtail-hljsAnd add wagtail_hljs to your INSTALLED_APPS setting:
INSTALLED_APPS = [
...
'wagtail_hljs',
...
]Wagtail Highlight.js supports all themes that Highlight.js supports. Here are a few of them:
- None: Default
- 'atom-one-dark': Atom One Dark
- 'base16/darcula': Base 16 Darcula
- 'nord': Nord
- 'srcery': Srcery
- 'xt256': XT256
- 'night-owl': Night Owl
For example, if you want to use the Night Owl theme: WAGTAIL_HLJS_THEME = 'night-owl'.
However, if you want the default theme then do this: WAGTAIL_HLJS_THEME=None.
You can customize the languages available by configuring WAGTAIL_HLJS_LANGUAGES in your Django settings.
By default, it will be set with these languages, since most users are in the Python web development community:
WAGTAIL_HLJS_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 Highlight.js code and a descriptive label. If you want use all available languages, here is a list:
