Building a templating renderer

Building a renderer that handles templating files is not that different from one that does serialization. In fact, the renderer itself is pretty much the same, outside of the library-specific code. This time, we'll use a Python library called tenjin. You may need to install it using pip:

# pip install tenjin

Templating with Tenjin

This module makes use of a third-party library, so there will be a __virtual__() function to make sure it's installed:

'''
Conver a file using the Tenjin templating engine

This file should be saved as salt/renderers/tenjin.py
'''
from __future__ import absolute_import
try:
    import tenjin
    from tenjin.helpers import *
    HAS_LIBS = True
except ImportError:
    HAS_LIBS = False
from salt.ext.six import string_types


def __virtual__():
    '''
    Only load if Tenjin is installed
    '''
    return HAS_LIBS


def render(tenjin_data, saltenv='base', sls='', **kwargs):
    '''
    Accepts a tenjin, and renders said data back to...
