Command line option to specify super class

[sharwell]

Derived from a comment in #36.

A command line option -superclass could be added to specify the super class of a generated lexer/parser.

Doesn't -DsuperClass work?

Just tested in trunk: -DsuperClass=Blah does not have any effect.

weird! it's a grammar option and i'm currently using in another repo.

    parserOptions.add("superClass");

classpath issue?

[mike-lischke]

Very strange. Whatever I tried yesterday it was wrong. I stand corrected. The option works (forcing the same super class on both parser + lexer, regardless whether such a class is set in the grammar options or not). Might be worth, however, to allow specifying individual super classes. What about accepting something like: -Dlexer::superClass -Dparser::superClass ...

Just as we would do it in the grammar (where we cannot specify indvidual super classes in a combined grammar, however).

crap. in my haste, did i make it superclass for both? actually that can't be as my lexer didn't break when i used it.

[mike-lischke]

Of that I'm sure. I saw it when I tested again today :-)

[parrt]

crap. ok, adding bug tag, leaving open. thanks!
