Generates files by parsing the environment with jinja2

Project Description

Render a file with jinja2 using a context built from processing environment variables.

Installation

From pip:

$ pip install env-render

Usage

To render a jinja document and collect all the environment variables with the prefix APP, enter this command:

$ env-render -p APP src_template.txt output.txt

Example

So imagine this environment:

APP_0_ENV0=a
APP_0_ENV1=b
APP_0_HOSTNAME=app_0
APP_1_ENV0=c
APP_1_ENV1=d
APP_1_HOSTNAME=app_1
APP_2_ENV0=e
APP_2_ENV1=f
APP_2_HOSTNAME=app_2

Becomes this dictionary:

{
    "apps": [
        {
            "_index": 0,
            "ENV0": "a",
            "ENV1": "b",
            "HOSTNAME": "app_0"
        },
        {
            "_index": 1,
            "ENV0": "c",
            "ENV1": "d",
            "HOSTNAME": "app_1"
        },
        {
            "_index": 2,
            "ENV0": "e",
            "ENV1": "f",
            "HOSTNAME": "app_2"
        }
    ]
}

Which can then be used like this in a file. Say an haproxy.cfg file:

listen someapp
    bind 0.0.0.0:80

    {% for app in apps %}
    server server{{ app._index }} {{ app.HOSTNAME }}:80
    {% endfor %}

This is what this library is meant to do.
