envsettings 2.1.0

Read settings from environment variables.

Easily read settings from environment variables. Reading settings from environment variables allows complete isolation between application and configuration data.

Read the Twelve-Factor App’s relevant section for more rationale behind this approach.


The following example will read the environment variables into configuration values host, port, and debug, cast to the expected type:

from envsettings import SettingsReader

r = SettingsReader(
    host=("HOST", "host", str),
    port=("PORT", "port", int),
    debug=("DEBUG", "debug", bool),

if r.debug:
   print("Running in debug mode"), r.port, debug=r.debug)

Boolean values can be either true, yes, or on and are case insensitive.


Any feedback is welcome, and please report any bugs you encounter on the project’s issue tracker.

Patches or merge requests are welcome.
