Overview

We allow a minimal configuration file to act as additional command line arguments to the CLI. Each line of the config file should be a new argument, as in:

--plugins=plugin/single_quote
--print-width=100

When invoking the CLI, we will read this config file and then parse it if it exists in the current working directory.
