Using rich.traceback with traceback.print_stack()

[remisphere]

Hello,
I would like to know if there is a way to format the output of the standard library's traceback.print_stack() using rich.traceback.

traceback.print_stack() displays a traceback where it is called, without interrupting the program,
but from the docs, it seems that rich.traceback needs to raise an exception to work.

Is there any workaround to pretty print a trace without ending a program ?
I would like to use it to pinpoint warnings, following the first part of this Stack Overflow answer.

Please see Printing Tracebacks section.

print_exception will only print a trace for exceptions. There's currently no way to just print the stack.

Ok, thank you, that was my question.
So there is no workaround.

It's not supported currently. You are the first to ask for it.

Yes I guess it is not something a lot of people would use.
I mostly use rich to format logs from loguru, that I also use to redirect warnings to logs by using the showwarning trick.
But by doing this, warnings now emanate from the showwarning function, so all the information I have are the warning messages.
Having the stack trace is useful, especially when the warnings come from dependency libraries.

I'd like that too. This is a function I created so I can sweet rich.traceback output whenever I want.

def pretty_trace():
    from rich.console import Console
    from rich.traceback import Traceback
    from sys import _getframe
    from types import TracebackType
    tb = None
    depth = 1
    while True:
        try:
            frame = _getframe(depth)
            depth += 1
        except ValueError as exc:
            break
        tb = TracebackType(tb, frame, frame.f_lasti, frame.f_lineno)
    ex = Exception('pretty_trace')
    stack = Traceback.extract(type(ex), ex, tb, show_locals=True)
    Console().print(Traceback(stack, show_locals=True))
