slimish-jinja 1.1.2
Slim templates syntax for Jinja2 templates
License: BSD

## [Slim](http://slim-lang.com/) 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::
