Module: Fontist::ThorExt::Start
- Included in:
- CLI
- Defined in:
- lib/fontist/cli/thor_ext.rb
Overview
Sources:
Configures Thor to behave more like a typical CLI, with better help and error handling.
-
Passing -h or –help to a command will show help for that command.
-
Unrecognized options will be treated as errors.
-
Error messages will be printed in red to stderr, without stack trace.
-
Errors will cause Thor to exit with a non-zero status.
To take advantage of this behavior, your CLI should subclass Thor and extend this module.
class CLI < Thor
extend ThorExt::Start
end
Start your CLI with:
CLI.start
In tests, prevent Kernel.exit from being called when an error occurs, like this:
CLI.start(args, exit_on_failure: false)
