Detect environment type and work within.

https://github.com/idlesign/envbox

Description

Detect environment type and work within.

Features

• Environment type detection (extendable system);

• Support for .env files;

• Convenient os.environ proxying (with optional values casting into Python natives);

• Automatic submodule-for-environment import tool;

• Cosy per-thread settings container with environment var support;

• CLI for environment probing.

Code sample

from envbox import get_environment

# Detect current environment type
# and get its object.
#
# Default detection sources:
# 1. ``PYTHON_ENV`` env variable
# 2. ``environment`` file contents
#
# By default this function will also try to read env variables from .env files.
env = get_environment()

env.name
# >> development

env.is_production
# >> False

env.get('HOME')
# The same as env['HOME'] and env.HOME
# >> /home/idle/

env.getmany('PYTHON')
# {'UNBUFFERED': '1', 'IOENCODING': 'UTF-8', 'PATH': ...}

Now you may want to put your environment vars into .env files (e.g.: .env, .env.development .env.production) to be read by envbox:

MY_VAR_1 = value1
HOME = /home/other/

# comments are ignored, just as lines without definitions

# mathing quotes (" and ') are stripped
MY_QUOTED = "some quoted "

# ${VARNAME} will be replaced by value from env (if available)
MY_VAR_2 = ${MY_QUOTED}

# multiline with dangling quotes
MULTI_1 = "
line1
line2
"

# multiline classic
MULTI_2 = "line1
line2
line3"

# multiline as one line
MULTI_3 = "one\ntwo"

Read the docs for more examples.

CLI

$ envbox probe
# >> Detected environment type: development (Development)

$ envbox show
# >> [...]
# >> SHELL = /bin/bash
# >> [...]

Note: envbox CLI requires click package available.
