Slim templates syntax for Jinja2 templates
Project description
Slim templates syntax for Jinja2.
This release breaks compatibility. Parsing = for Jinja Output is complex. I dropped it in favor of directly using {{ jinja_output }}.
This release(1.0) onwards, the backward syntax compatibility will be maintained.
Installation
pip install slimish_jinja
Examples of using it as Jinja2 extension(jinja_demo.py),
with Flask(flask_demo.py) and standalone(convert.py and demo.py) are bundled.
If you want to use it for any other purpose, the lexer - lexer.py and parser - parser.py are simple enough.
lexer reads the input by lines and generates tokens. parser implements a hand rolled recursive descent parser.
For quick reference, this slim::
