Configuration#

The configuration class is defined in configuration.py. From CLI, you can load custom configuration yaml with -c or --config argument. From Python, you can replace the default configuration with

from pathlib import Path
import sec_certs.configuration as config_module

config_module.config.load_from_yaml("/path/to/your/config.yaml")

# or just set the individual key
config_module.config.log_filepath = Path("/some/path/where/log/will/be/stored.txt")

The configuration yaml is a simple flat dictionary of keys and values. The configuration file can specify only some of the fields. For the content of unspecified fields, environment variable with seccerts_ prefix (case insensitive) will be checked. If such variable is not set, default value will be used. Content in the yaml always beats the environment variable.

For instance, when user provides the following yaml

log_filepath: my_own_log_file.txt
n_threads: 7

and sets SECCERTS_MINIMAL_TOKEN_LENGTH=4 as environment variable, only these 3 keys will be loaded with config.load_from_yaml(), others will be untouched.

Tip

You can load settings even without providing yaml configuration. Simply set the corresponding environment variables or use .env file.
