moban brings the high performance template engine (JINJA2) for web into static text generation. It is used in pyexcel project to keep documentation consistent across the documentations of individual libraries.

Installation

You can install it via pip:

$ pip install moban

or clone it and install it:

$ git clone http://github.com/moremoban/moban.git
$ cd moban
$ python setup.py install

Quick start

$ export HELLO="world"
$ moban "{{HELLO}}"
Warning: Both data.yml and /.../.moban.cd/data.yml does not exist
Warning: Attempting to use environment vars as data...
Templating {{HELLO}}... to moban.output
Templated 1 file.
$ cat moban.output
world

Or simply

$ HELLO="world" moban "{{HELLO}}"

A bit formal example:

$ moban -c data.yml -t my.template
$ cat moban.output

Given data.yml as:

hello: world

and my.template as:

{{hello}}

moban.output will contain:

world

Please note that data.yml will take precedence over environment variables.

the tutorial has more use cases.
