Harmoniser CLI

Harmoniser CLI is a command line tool than run a Ruby process through bundle exec harmoniser. This utility accepts the following options:

bundle exec bin/harmoniser -h

harmoniser [options]
-e, --environment ENV            Set the application environment (defaults to inferred environment or 'production')
-r, --require [PATH|DIR]         Specify a file to require or the location of the Rails application
-v, --[no-]verbose               Run verbosely (set log severity to 'debug' for detailed RabbitMQ interactions)
-V, --version                    Print version and exit
-h, --help                       Show help

The environment is automatically inferred from the environment variables RAILS_ENV or RACK_ENV, otherwise fallbacks to production. However you can specify your preferred value, for instance development or test.

The require is by default pointing at ., which means that this option when configured under a Rails application, might be ignored. Since Ruby is not Rails only, you can certainly specify the location path of your Ruby file that will be used to load the classes including Harmoniser::Subscriber. In contrast, if a path to a directory is passed, Harmoniser assumes that ./config/environment.rb lives within the folder passed as option.

The verbose option, when passed, sets the severity of Harmoniser logs to debug being able to see fine-grained details of things like RabbitMQ interactions happening or messages published into exchanges. By default, the verbosity is disabled to prevent your environment to be flooded with unnecessary logs.
