defaultDescription behaviour has changed between 1.2.0 and 1.2.0-M2

[YannMoisan]

With version 1.2.0, it seems that defaultDescription are always set to None

Here is a small example to reproduce the bug : https://scastie.scala-lang.org/YgickCTpTkWDK7xpoVTOJw

Arg(i,List(Name(i)),None,None,false,false,int,None)
Arg(s,List(Name(s)),None,None,false,false,string,None)
Arg(b,List(Name(b)),None,None,false,true,bool,None)
Arg(li,List(Name(li)),None,None,false,false,int*,None)

And it works with version 1.2.0-M2

Arg(i,List(Name(i)),None,None,false,false,int,Some(2))
Arg(s,List(Name(s)),None,None,false,false,string,Some("defaultt"))
Arg(b,List(Name(b)),None,None,false,true,bool,Some(false))
Arg(li,List(Name(li)),None,None,false,false,int*,Some(List()))

After searching a bit, it seems related to this commit d292098

I've just found a workaround by importing import core.Defaults._

But I don't know how to use it with this syntax object Example extends CaseApp[ExampleOptions]

[alexarchambault]

@YannMoisan It should work out-of-the-box with it, like

import caseapp._
import caseapp.core.Defaults._

object Example extends CaseApp[ExampleOptions]

(doesn't it for you?) The Parser is derived along CaseApp.

It works ! I was misled by IntelliJ that displays unused import.
