python-pie 0.2.0

Parse static files such as YAML and insert in them data from environment variables

python-pie

Python-pie(python insert env) reads key-value pairs from a .env file and can set them as environment variables. It helps in the development of applications following the

Getting Started

pip install python-pie

You can use python-pie to insert env variables to static configurations, like that:

from pie import process_file

filepath = '/docker/configuration.yaml'
process_file(filepath)

The syntax of files supported by python-pie is similar to that of python fstrings:

f"54 {from_env or 'default_value'} some text"

Depends if your environment has a from_env variable or not, python-pie will load it, or in case of absence take the default value

Syntax example

hosts:
  - f"{host}"

loglevel: 4
f"{'log_file_path'}": f"/file/path/{filename or 'tmp.log'}"
log_rotate_count: 1

after process_file(filepath)

hosts:
  - localohst

loglevel: 4
log_file_path: /file/path/tmp.log
log_rotate_count: 1
