Get some linting tools. They're great for catching this kind of error.
SublimeText has SublimeLinter and PycodeStyle installed, but I'm still
familiarising myself with ST. Nothing is reported.
Any advice/correction/improvement would be most welcome...
Hmm. I'd expect a linter to catch this:
# forgot FooException
from foo import FooClass
def f():
raise FooException
Can you test that with a small script at your end (with real imports and
names of course)?
I lint from the command line with this script:
https://bitbucket.org/cameron_simpson/css/src/tip/bin-cs/lint
which runs a few Python linters for Python.
WRT SublimeText, PycodeStyle likely only checks style (I've now shifted
to an automatic formatter for this) and SublimeLinter's PythonLinter
page is... silent; it looks like a base class for other actual linters.
You might need to do some more digging. Maybe you need some addition
lint stuff for SublimeText.
The tricky bit with dynamic language like Python is that some naming
errors (missed imports) aren't apparent until the code passes through
that path. Linters can cover a lot of this with static analysis.
Exactly!
(PyTest and coverage tools were no help - they import correctly (and
test adequately), but I didn't open those (separate) modules to notice
the multiple import-s)
Hope springs eternal ... there must be a better way???
A good linter is usually decent at complaining about code using names
that aren't defined (not imports, not otherwise defined such as a
function or a variable assignment).
(well yes, not wishing to 'flog a dead horse' (nor any horse for that
matter) I'm pleased at the (lack of negative) response to my allied
question about nested classes, which would solve the original problem)
There's nothing "wrong" with it. It is uncommon. But like a lot of
things, the value (or cost/pitfalls) come with how things are to be
used.
