would be usefull as a way for pthers to integrate other debuggers/tools

and what's the behaviour exactly?

• restore normal stdout/err
• print the current output
• call function
• restore capture

could have a better name

Hmmm in order to suspend capture, one would have to have access to the CaptureManager plugin in order to be able to call suspendcapture_item and resumecapture during the pytest.no_capture call (I think pytest.disable_capture would be better btw).

How about adding context manager support to capsys and capfd like this:

def test_foo(capsys):
    print('captured')
    with capsys.disabled():
         print('directly to stdout, regardless of the "-s" flag')
    print('captured again')

?

nice idea 👍

[hpk42]

why would the disabled() call send things to the users stdout instead of it going to normal pytest capturing? i am kind of missing the problem statement and why it would help with debuggers.

[RonnyPfannschmidt]

basically all debuggers currently break due to missing integration (with the notable exception of pdbpp)

Another related issue is if you're mucking about with terminal settings as detailed in #1182 (closed as it should be resolved by the solution being discussed here). Because the object responsible for capturing doesn't implement the full file API (specifically fileno is where I got to), it fails when capturing is on.

Having the ability to disable capturing for a specific test would also solve this problem.

Closing this one since its badly scoped, capture related items will happen later
