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.

Usage

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

                        will try to use environment vars as data
  -td [TEMPLATE_DIR [TEMPLATE_DIR ...]], --template_dir [TEMPLATE_DIR [TEMPLATE_DIR ...]]
                        the directories for template file lookup
  -t TEMPLATE, --template TEMPLATE

With –exit-code:

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.jjs 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.jjs 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
