distillery v0.7.0 Config

This module handles fetching values from the config with some additional niceties

Summary

Functions

Fetches a value from the config, or from the environment if {:system, “VAR”} is provided. An optional default value can be provided if desired

Same as get/3, but returns the result as an integer. If the value cannot be converted to an integer, the default is returned instead

Functions

get(app, key, default \\ nil)
