[Xbase] Change keywords of XSwitchExpression [message #1079935]

Hi,

I would like to change the keywords for the XSwitchExpression in Xbase. I would like to transform this:

    switch e {
    case e1 : er1
    ...
    case en : ern
    default : er
    }

to that:

    case of e {
    case e1 : er1
    ...
    case en : ern
    otherwise : er
    }

I managed the "case of" and "otherwise" bits but now the parser complains if I try to write "case" statements, because it expects "case of" and not "case" even so I did not change anything in the XCasePart rule. I guess I have to use syntactic predicates but I could not make it work.

Is this possible somehow?

Thanks
Jan

Hi Jan,

make sure that you use 'case' 'of' rather than 'case of', e.g. the space
should not be part of the keyword.
