django-classy-tags's goal is to create a new way of writing Django template tags which is fully compatible with the current Django templating infrastructure. This new way should be easy, clean and require as little boilerplate code as possible while still staying as powerful as possible.
For the impatient
This is how a tag looks like using django-classy-tags:
from classytags.core import Tag, Options
from classytags.arguments import Argument
from django import template
register = template.Library()
class Hello(Tag):
options = Options(
Argument('name', required=False, default='world'),
'as',
Argument('varname', required=False, no_resolve=True)
)
def render_tag(self, context, name, varname):
output = 'hello %s' % name
if varname:
context[varname] = output
return ''
return output
register.tag(Hello)
That's your standard hello world example. Which can be used like this:
* {% hello %}: Outputs hello world
* {% hello "classytags" %}: Outputs hello classytags
* {% hello as myvar %}: Outputs nothing but stores hello world into the template variable myvar.
* {% hello "my friend" as othervar %}: Outputs nothing but stores hello my friend into the template variable othervar.
Here are some key features of "django-classy-tags":
· Class based template tags.
· Template tag argument parser.
· Declarative way to define arguments.
· Supports (theoretically infinite) parse-until blocks.
· Extensible!
Requirements:
· Python
· Django
