Django

In settings.py, add a loader to TEMPLATES like so:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                'django.core.context_processors.request'
            ],
            'loaders': [
                # PyJade part:   ##############################
                ('pyjade.ext.django.Loader', (
                    'django.template.loaders.filesystem.Loader',
                    'django.template.loaders.app_directories.Loader',
                ))
            ],
            'builtins': ['pyjade.ext.django.templatetags'],  # Remove this line for Django 1.8
        },
    },
]

Jinja2

Just add pyjade.ext.jinja.PyJadeExtension as extension

jinja_env = Environment(extensions=['pyjade.ext.jinja.PyJadeExtension'])

Mako

Just add pyjade.ext.mako.preprocessor as preprocessor

from pyjade.ext.mako import preprocessor as mako_preprocessor
mako.template.Template(haml_source,
    preprocessor=mako_preprocessor
)

Flask

Just add pyjade.ext.jinja.PyJadeExtension as extension to the environment of the app

app.jinja_env.add_extension('pyjade.ext.jinja.PyJadeExtension')

Pyramid

Adjust your “your_project/__init__.py” and add the following line somewhere to in the main() function

config.include('pyjade.ext.pyramid')

Tornado Templates

Append this after importing tornado.template

from tornado import template
from pyjade.ext.tornado import patch_tornado
patch_tornado()

(...)
