A library to make Jinja2 Extensions Easy

Project description

A Library to Quickly Turn Functions into Jinja2 Extensions
==========================================================

This library is best demonstrated through example:

```python
import jinjatag

### Configure your Jinja2 Environment:
jinja_tag = jinjatag.JinjaTag()
jinja2_env = Environment(extensions=[jinja_tag])
jinja_tag.init()

### Decorate your functions

@jinjatag.simple_tag()
def mytag(foo, bar=None, **kwargs):
return "mytag: "+foo+(bar or '')+str(kwargs)

@jinjatag.simple_block()
def myblock(body, foo, bar=None):
return "myblock : "+body+foo+(bar or '')

```

Then, in your template code, use your new tags:

{% mytag foo='abc' xyz='def' %}

{% myblock foo='bar' %}contents{% endmyblock %}

The resulting output:

mytag: abc{'xyz':'def'}

myblock: contentsbar

That's really all there is to it. A simple_tag is expected to accept 0 or more
arguments and return a string. A simple_block is expected to accept at least
one argument which will be the its rendered body.
