django-meio-easytags
====================

An easy way to create custom template tags for Django's templating system.

Usage
=====

Just subclass the EasyNode and create the method render_context and register
the template tag::

	from django.template import Library
	from easytags.node import EasyNode
	
	register = Library()
	
	class SumNode(EasyNode):
	
	    def render_context(self, context, arg1, arg2, arg3=0):
	        return int(arg1) + int(arg2) + int(arg3)
	
	register.tag('sum', SumNode.parse)

EasyNode will take care of the template tag's parsing, resolving variable
and inspecting if the args are ok with the ``render_context`` signature.
In the example above, you can use the sum tag in any of the forms below::

	{% sum "1" "2" %}
	{% sum "1" arg2="2" %}
	{% sum arg1="1" arg2="2" %}
	{% sum arg2="2" arg1="1" %}

It's almost like calling methods in Python.

In this example, ``arg3`` is optional and defaults to 0. So you may use or not this arg.
