Installation

Muffin-Jinja2 should be installed using pip:

pip install muffin-jinja2

Usage

import muffin
import muffin_jinja2

# Create Muffin Application
app = muffin.Application('example')

# Initialize the plugin
# As alternative: jinja2 = Jinja2(app, **options)
jinja2 = muffin_jinja2.Plugin()
jinja2.setup(app, template_folders=['src/templates'])

# Use it inside your handlers
@app.route('/')
async def index(request):
    context = {'var': 42}
    return await jinja2.render('index.html', **context)

Options

Name	Default value	Description
auto_reload	False	Auto reload changed templates
cache_size	50	Cache templates
extensions	None	Enable Jinja2 Extensions (None | list)
loader	FileSystemLoader	Template loader
encoding	utf-8	Default encoding for file loader
template_folders	['templates']	List of template folders

You are able to provide the options when you are initiliazing the plugin:

jinja2.init(app, template_folders=['src/templates'], auto_reload=True)

Or setup it inside Muffin.Application config using the jinja2_ prefix for example:

JINJA2_AUTO_RELOAD = True

JINJA2_TEMPLATE_FOLDERS = ['tmpls']

Muffin.Application configuration options are case insensitive

Tunning

# Register custom context processor
# could be a function/coroutine
@jinja2.context_processor
def custom_context():
    return { 'VAR': 'VALUE' }

# Register a function into global context
@jinja2.register
def sum(a, b):
    return a + b

# Register a function with a different name
@jinja2.register('div')
def mod(a, b):
    return a // b

# Register a filter
@jinja2.filter
def test(value, a, b=None):
    return a if value else b

# Register a filter with a different name
@jinja2.filter('bool')
def boolean(value):
    return bool(value)

@app.route('/')
async def index(request):
    """ Check for user is admin. """
    local_context = {'key': 'value'}
    return await jinja2.render('index.html', **local_context)
