Hey Steve,
I think what you’re looking for is the args property.
Check out the examples here: http://groovy.codehaus.org/gapi/groovy/util/CliBuilder.html

In particular look at the example provided emulating the ant command line:

cli.logfile(args:1, argName:’file’, ‘use given file for log’)
cli.D(args:2, valueSeparator:’=', argName:’property=value’,
‘use value for given property’)

I have yet to find a way to handle the -foo=bar option. Does the CLIBuilder do this? If it does, where can I find an example of this syntax? right now I have written it myself using a for loop and making it in the format of -f bar…but I am sure there is a better way to do this.

Each option is of type org.apache.commons.cli.Option. This class contains an arg property, which allows you to set the maximum number of args a given property can accept. Take a look here:

How do you allow for options that can appear more than once? This means that you have to be able to iterate through the provided options in some way.

I’d have to say that the CliBuilder doc is less than informative.

Thanks for the pointer Guillaume. By the way I’ve been reading about Gaelyk recently. I think it’s a very timely addition! I’m looking forward to writing about it here in the future.

You may make it a tiny bit groovier with using “with()”:

cli.with {
h longOpt: ‘…’, ‘…’
u longOpt: ‘…’, ‘…’
}
