Jade syntax adapter for Django, Jinja2 and Mako templates

PyJade

PyJade is a high performance port of Jade-lang for python, that converts any .jade source to the each Template-language (Django, Jinja2, Mako or Tornado).

UTILITIES

To simply output the conversion to your console:

pyjade [-c django|jinja|mako|tornado] input.jade [output.html]

or, alternatively:

pyjade [-c django|jinja|mako|tornado] [-o output.html] < input.jade

To convert directly inside a python script:

import pyjade
jade_text = '''!!! 5
html
head
    body foo bar!
'''
print pyjade.simple_convert(jade_text)

INSTALLATION

First, you must do:

pip install pyjade

Or:

python setup.py install

Now simply name your templates with a .jade extension and this jade compiler will do the rest. Any templates with other extensions will not be compiled with the pyjade compiler.

Django

For Django 1.9

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'],
        },
    },
]

For Django 1.8

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',
                ))
            ],
        },
    },
]

Or, in Django 1.7 or earlier:

In settings.py, modify TEMPLATE_LOADERS like:

TEMPLATE_LOADERS = (
    ('pyjade.ext.django.Loader',(
        'django.template.loaders.filesystem.Loader',
        'django.template.loaders.app_directories.Loader',
    )),
)

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(jade_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()

(...)

Syntax

Exactly the same as the Jade Node.js module (except of cases, which are not implemented) https://github.com/visionmedia/jade/blob/master/README.md

Example

This code:

!!! 5
html(lang="en")
  head
    title= pageTitle
    script(type='text/javascript').
      if (foo) {
         bar()
      }
  body
    h1.title Jade - node template engine
    #container
      if youAreUsingJade
        p You are amazing
      else
        p Get on it!

Converts to:

<!DOCTYPE html>
<html lang="en">
  <head>
    <title>{{pageTitle}}</title>
    <script type='text/javascript'>
      if (foo) {
         bar()
      }
    </script>
  </head>
  <body>
    <h1 class="title">Jade - node template engine</h1>
    <div id="container">
      {%if youAreUsingJade%}
        <p>You are amazing</p>
      {%else%}
        <p>Get on it!</p>
      {%endif%}
    </div>
  </body>
</html>

Register filters

If you want to register a function as a filter, you only have to decorate the function with pyjade.register_filter("filter_name")

import pyjade

@pyjade.register_filter('capitalize')
def capitalize(text,ast):
  return text.capitalize()

Using templatetags (and any feature of the compiled-to language)

Using Django and crispy-forms as an illustrative example but the information can be generalized.

If you need to use templatetags, you can use Jade's syntax for rendering code:

- load crispy_forms_tags
- crispy form

This will compile into

{% load crispy_forms_tags %}
{% crispy form %}

If you have any trouble with this feature, or there's some feature of your template language that is being misinterpreted when using this syntax, you can also do something like this:

| {% load crispy_forms_tags %}
| {% crispy form %}

This will compile into the same Django template snippet.

TESTING

You must have nose package installed. You can do the tests with

./test.sh
