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, line numbering, and support for PrismJS themes.
It uses the PrismJS library both in Wagtail Admin and the website.
from wagtailcodeblock.blocks import CodeBlock
class ContentStreamBlock(StreamBlock):
heading = TextBlock()
paragraph = TextBlock()
code = CodeBlock(label='Code')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:
bash_code = CodeBlock(label='Bash Code', language='bash')
any_code = CodeBlock(label='Any code', default_language='python')
To install Wagtail Code Block run:
# Wagtail 3.0 and greater
pip install wagtailcodeblock
# Wagtail 2.x
pip install wagtailcodeblock==1.25.0.2And add wagtailcodeblock to your INSTALLED_APPS setting:
INSTALLED_APPS = [
...
'wagtailcodeblock',
...
]Line numbers are enabled by default, but can be disabled in Django's settings:
WAGTAIL_CODE_BLOCK_LINE_NUMBERS = FalseCopy to clipboard is enabled by default, but can be disabled in Django's settings:
WAGTAIL_CODE_BLOCK_COPY_TO_CLIPBOARD = FalseWagtail 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: Default
- 'coy': Coy
- 'dark': Dark
- 'funky': Funky
- 'okaidia': Okaidia
- 'solarizedlight': Solarized Light
- 'twilight': Twilight
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
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:
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:

This package was created by the staff of Wharton Research Data Services. We are thrilled that The Wharton School allows us a certain amount of time to contribute to open-source projects. We add features as they are necessary for our projects, and try to keep up with Issues and Pull Requests as best we can. Due to constraints of time (our full time jobs!), Feature Requests without a Pull Request may not be implemented, but we are always open to new ideas and grateful for contributions and our users.
