[forge-users] @Option explanations please

[George Gastaldi]

Hi Jérôme,

value() is meant to be the parameter name. Since this annotation method can be written in the form @Option("named"), we (the forge team) decided to use it to represent the option name. (Eg: my-command --named xxx)

DefaultValue as the name implies is the value set in the option when it is not filled.

The "type" as the javadoc states, is the input type hint (eg: should the option be rendered as a combo box, radio buttons, etc) and the valid values are defined in the InputType interface. In order to allow extensibility, we decided to use String to represent it, so people could write plugin extensions and render an input in the way they like. As you might have guessed, it is not used in the CLI version, only in IDEs.

Let me know if I have answered your questions, looking forward to reading this article ;)

Best Regards,

George Gastaldi
