Overview

Provider that looks through provided command line arguments for configuration overrides

This provider assumes all configurations will be supplied in the format of --config.name=new_val . To make this approach workable with OptionParser, any configurations discovered through command line arguments will be removed from the ARGV array, so that OptionParser won't error for unrecognized options. This requires the configuration class to be constructed before the OptionParser.parse method gets called.

Defined in:

cr-config/abstract_provider.cr
