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

Our vision is: any template, any data. Our current architecture enables moban to plugin any python template engine: mako, handlebars, velocity, haml, slim and tornado and to plugin any data format: json and yaml. Please look at our issues. We have many more template engines and data format on the road map.

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.

Usage

usage: moban [-h] [-cd CONFIGURATION_DIR] [-c CONFIGURATION]
             [-td [TEMPLATE_DIR [TEMPLATE_DIR ...]]] [-t TEMPLATE] [-o OUTPUT]
             [-f] [-m MOBANFILE]

Built-in Filters

split_length

It breaks down the given string into a fixed length paragraph. Here is the syntax:

{% for line in your_string | split_length(your_line_with) %}
{{line}}
{% endfor %}

It is used to keep changelog formatted in CHANGELOG.rst.jj2 in pypi-mobans project

github_expand

It expands simple hashtags into github issues. Here is the syntax:

{{ your_github_string | github_expand }}

It makes it easy to mention github reference in change log in all projects. Here is the place it is applied: CHANGELOG.rst.jj2 in pypi-mobans project

Here is Grammar in the changelog.yml:

=============== ==============================
Syntax          Meaning
=============== ==============================
`#1`            moban issues 1
`PR#1`          moban pull request 1
`pyexcel#1`     other project issues 1
`pyexcel#PR#1`  other project pulll request 1
=============== ==============================

More details can be found in moban’s changelog.yml
