metabolenv-flag 1.1.0

Get boolean values from environment variables in Python.

from env_flag import env_flag

# When unset, default to `False`.
debug = not env_flag('PRODUCTION')

# When unset, use explicit default.
is_local = get_bool('IS_LOCAL', default=True)

Values are coerced as follows:

• When the variable is unset, or set to the empty string, return default.

• When the variable is set to a truthy value, return True. These are the truthy values:

  • 1

  • true, yes, on

• When the variable is set to the anything else, return False. Example falsy values:

  • 0

  • no

• Ignore case and leading/trailing whitespace.
