Config files renderer based on Jinja2

Project description

It renders template files with context loaded from simple INI-style config files. Config files support inheritance and interpolation.

Getting started

Install this package with pip:

$ pip install jingle

Check usage:

$ jingle --help

Run some examples:

$ jingle examples/hello.conf < examples/hello.j2

Config files

Jingle supports single-group INI config files. For example:

one = 1
two = dos
three = trzy

Interpolation

Basic interpolation is supported thanks to SafeConfigParser used under the hood:

name = Jon
surname = Snow
fullname = %(name)s %(surname)s

Inheritance

Config files can be inherited, or saying precisely included one into another with #inherit directive.

In defaults.conf:

host = 0.0.0.0
port = 3000

In production.conf:

#inherit defaults.conf
port = 80

Compiled config will use host: 0.0.0.0 and port: 80.

Of course interpolation works across inherited files.

Programatic usage

You can as well use the library programatically in your application. Here’s simple example:

from jingle import Template, Context

tpl = Template("Hello {{who}}!")
print tpl.render(Context("path/to/params.conf"))
