Hi Imesh, I have now pushed my changes to [1].
Did we had a discussion on selecting Jinja as a template engine for this? I > would like to see a review of Jinja compared to other python based template > engines and reasons for selecting it. Following are the technologies available similar to jinja <http://jinja.pocoo.org/>. Mako <http://www.makotemplates.org/> Genshi <http://genshi.edgewall.org/> Django <https://www.djangoproject.com/> According to the Jinja website benchmarks from the testsuite show that Jinja2 has a similar performance to Mako and is between 10 and 20 times faster than Django’s template engine or Genshi[2]. Further more the [3] contains detailed comparison with real values.
