Announcement

For existing moban users, python 2 support has been dropped. Please stay with versions lower than 0.7.0 if you are still using python 2.

From 2020 onwards, minimum requirement is Python 3.6

Introduction

moban started with bringing the high performance template engine (JINJA2) for web into static text generation. It has been used in pyexcel and coala project to keep documentation consistent across the documentations of individual libraries in the same organisation.

moban can use other python template engine: mako, handlebars, velocity, haml, slim and tornado, can read other data format: json and yaml, and can access both template file and configuration file in any location: zip, git, pypi package, s3, etc.

Vision

Any template, any data in any location

Support

If you like moban, please support me on github, patreon or bounty source to maintain the project and develop it further.

With your financial support, I will be able to invest a little bit more time in coding, documentation and writing interesting extensions.

Credit

jinja2-fsloader is the key component to enable PyFilesystem2 support in moban v0.6x. Please show your stars there too!

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}}"
Templating {{HELLO}}... to moban.output
Templated 1 file.
$ cat moban.output
world

Or

$ export HELLO="world"
$ echo "{{HELLO}}" | moban

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.

All use cases are documented here

Work with files in a git repo

gitfs2 is optional since v0.7.0 but was installed by default since v0.6.1

You can do the following with moban:

$ moban -t 'git://github.com/moremoban/pypi-mobans.git!/templates/_version.py.jj2' \
        -c 'git://github.com/moremoban/pypi-mobans.git!/config/data.yml' \
        -o _version.py
Info: Found repo in /Users/jaska/Library/Caches/gitfs2/repos/pypi-mobans
Templating git://github.com/moremoban/pypi-mobans.git!/templates/_version.py.jj2 to _version.py
Templated 1 file.
$ cat _version.py
__version__ = "0.1.1rc3"
__author__ = "C.W."

Work with files in a python package

pypifs is optional since v0.7.0 but was installed by default since v0.6.1

You can do the following with moban:

$ moban -t 'pypi://pypi-mobans-pkg/resources/templates/_version.py.jj2' \
        -c 'pypi://pypi-mobans-pkg/resources/config/data.yml' \
        -o _version.py
Collecting pypi-mobans-pkg
....
Installing collected packages: pypi-mobans-pkg
Successfully installed pypi-mobans-pkg-0.0.7
Templating pypi://pypi-mobans-pkg/resources/templates/_version.py.jj2 to _version.py
Templated 1 file.
$ cat _version.py
__version__ = "0.1.1rc3"
__author__ = "C.W."

Work with S3 and other cloud based file systems

Please install fs-s3fs:

$ pip install fs-s3fs

Then you can access your files in s3 bucket:

$ moban -c s3://${client_id}:${client_secrect}@moremoban/s3data.yml \
        -o 'zip://my.zip!/moban.output' {{hello}}
$ unzip my.zip
$ cat moban.output
world

Where the configuration sits in a s3 bucket, the output is a file in a zip. The content of s3data.yaml is:

hello: world
