A milestone. The new ATTRIBUTE visitor checks for the attributes of the
Commands, Position, and leoGlobals modules as follows, where leoC, leoG,
and leoP are the live c, g, and p objects passed to my @button test script:
def ATTRIBUTE(self, node) -> None:
if isinstance(node.value, ast.Name):
base = node.value.id
attr = node.attr
table = (
(leoC, ('c', 'c1', 'c2')),
(leoG, ('g', 'leoGlobals')),
(leoP, ('p', 'p1', 'p2')),
)
for obj, bases in table:
if base in bases and not hasattr(obj, attr):
self.report(messages.UndefinedName, node, f"{base}.{attr}")
return # Otherwise pyflakes reports both base and attr as
changed.
self.handleChildren(node)
g.funcToMethod(ATTRIBUTE, Checker)
A check of the entire leoApp.py file shows that this no code makes no
noticeable difference to pyflakes's speed. The patched pyflakes takes 0.05
sec.
This hack does about 90% of what I've ever wanted an enhanced pylint to do!
