I have a python file:

def do_something():
    pass

def main():
    a = 1
    b = 2
    c = a+b
    print(f"c:{c}")
    pass

if __name__ == '__main__':
    main()

I run this command:

python -m pdb -c "b 5" -c "commands 1;;do_something();;end" -c "c" main.py

It doesn't work.
And I have a .pdbrc file

b 5
commands 1
do_something()
end
c

It doesn't work either.

Would I be able to get some clarification if this is even supposed to be possible? I myself had a desire to do this and have performed the necessary setup to make an attempt at making this possible but given the long standing stack overflow post about this, I'm not sure if this is even a bug or not.

This is fixed now, you can define any commands/aliases in .pdbrc as you want.

Just wanted to drop a quick thank you for fixing this bug that's been lurking around for ages. Huge relief to see it finally squashed!

Okay I'll do a PR to keep the consistency of the behavior and update the docs (in a way that can be applied to 3.12 and 3.11 as well because no behavior is changed).

Okay we restored the behavior for 3.12 and 3.11, and we also updated the docs to clarify the behavior of .pdbrc. I'll close this. Let us know if there are more stuff to do for the matter.

wow, that was quick. thanks 🙏🏼
