Hi guys,
just wanted to say that I recently had to revisit some older Groovy script code
in my project, and I took the opportunity to switch the old CliBuilder
implementation to the new Picocli based one
(http://docs.groovy-lang.org/latest/html/gapi/groovy/cli/commons/CliBuilder.html
) - and I can just say that it is an absolute joy to work with: Concise,
elegant, and type safe G-)
import groovy.cli.commons.CliBuilder
import groovy.cli.Option
import groovy.cli.Unparsed
// Alternative is to use an interface and let Groovy instantiate a class
instance from it
class MyOptions {
boolean isTestRun
@Option(shortName='h', description='output help info') Boolean help
@Option(shortName='r', description='process regular entries') Boolean regular
// etc (for supported types outside of Boolean see URL above)
@Unparsed List remaining // all additional options given
MyScriptOptions(boolean isTestRun) { this.isTestRun = isTestRun }
}
final cli = new CliBuilder(usage:'my_powerful_groovy_script')
def opts = new MyOptions(true)
cli.parseFromInstance(opts, args.split()) // From now on all cmd line
params can be accessed in a type safe manner
if(opts.help) {
println cli.usage()
System.exit(0)
}
if(opts.regular) {
...
}
Cheers,
mg
