Hello
The following cut-down version of a larger script raises “KeyError:
'~'” in pyreverse. As in my previous bug report, this script wouldn't
work on its own, but it reproduces the error. A complete backtrace can
be found at the end of this e-mail.
------------------------------------------------
import pyparsing as pyp
class MyClass(MyBase):
def xyz(self):
rbrace = pyp.Literal("}").suppress()
stmt = (~rbrace + keyword + ~lbrace)
------------------------------------------------
Using pyreverse as included in the following pylint version:
$ pylint --version
pylint 0.19.0,
astng 0.19.3, common 0.46.0
Python 2.5.2
Thanks,
Michael
