Hello,
I've written a method, which transforms Arguments of a CLArgsParser into a
Configuration. In my test environment it seems to work good, so now, I'm
asking for some comments. I'd like to get it included into Avalon Framework
or Excalibur. Thats one of the option questions. Should it be a
toConfiguration in CLArgsParser or a fromCLArgsParser in Configuration? The
other question is the way to parameters are transformed into a Configuration.
Currently I'm using points (.) as a seperator to generate childs. A double
point (:) is used as mark for an attribute.
I have attached a test class.
With kind regards
Torsten Knodt
