There was a problem hiding this comment.
I found this rule to be close to what I wanted, except that there remains a trailing whitespace when a line is wrapped. I didn't know how to fix this, and figured it was good enough for now.

Additionally, it improves the typing of a number of obvious methods. The typing remains incomplete however.
The changes to
XPathLexer.pyare fully auto-generated (with the exception of thecheckVersioncall).In the future, I would work towards removing the
from antlr4 import *and replacing it with named imports.I have validated this against a mildly complex parser grammar in https://github.com/SciTools/cf-units/blob/main/cf_units/_udunits2_parser/udunits2Parser.g4.
