mix loadconfig (Mix v1.13.0-dev) View Source
Loads and persists the given configuration.
mix loadconfig path/to/config.exs
Any configuration file loaded with
loadconfig is treated
as a compile-time configuration.
Note that "config/config.exs" is always loaded automatically
by the Mix CLI when it boots. "config/runtime.exs" is loaded
mix app.config before starting the current
application. Therefore there is no need to load those config
This task is automatically reenabled, so it can be called multiple times to load different configs.
