Default value for missing environment variables in yaml and ini config files #459
Description
How could I specify a default value for the missing environment variable in the configuration provider?
For example:
pseudo code
config = dependency_injector.providers.Configuration() config.from_yaml("conf.yml") print(config.some_key.size) -> will print ${SOME_KEY_SIZE} if envvar is missing conf file
some_key: size: ${SOME_KEY_SIZE} or maybe we could leave such cases with empty/none values? for e.g.
config.some_key.size -> will be None
