Config.import_config
You're seeing just the macro
import_config
, go back to Config module for more information.
Imports configuration from the given file.
In case the file doesn't exist, an error is raised.
If file is a relative, it will be expanded relatively to the directory the current configuration file is in.
Examples
This is often used to emulate configuration across environments:
import_config "#{config_env()}.exs"
Note, however, some configuration files, such as config/runtime.exs
does not support imports, as they are meant to be copied across
systems.
