[Python-porting] 2to3 pattern matching help needed.

[Lennart Regebro]

Help! I need a pattern to match the following code:

@implementor(IFoo)
class C(object):
    implements(IFoo)
    classProvides(IFooFactory

find_pattern claims that this code should match:

"decorated< decorator< '@' 'implementer' '(' 'IFoo' ')' '\n' >
classdef< 'class' 'C' '(' 'object' ')' ':' suite< '\n' '    '
simple_stmt< power< 'implements' trailer< '(' 'IFoo' ')' > > '\n' >
simple_stmt< power< 'classProvides' trailer< '(' 'IFooFactory' ')' > >
'\n' > '' > > >"

It does not match.


I already have the following similar pattern:

"classdef< 'class' any* ':' suite< any* simple_stmt< power<
statement=(%s) trailer < '(' interface=any ')' > any* > any* > any* >
>"

which matches the following code:

class C(object):
    implements(IFoo)
    classProvides(IFooFactory

I.e, the same code but without the decorator. But I also need to match
even of the class has decorators, as in the beginning example. If the
decorator matching code is the same or a separate that the one I have,
that doesn't handle decorators, doesn't matter.
