Custom traceback is being overridden when importing exceptiongroup

[Tsimopak]

I took as a reference the source code of exceptiongroup in order to make a custom exception of my own with a custom traceback .

It worked as expected, the thing is, when I import exceptiongroup, it overrides the traceback exception from the exceptiongroup.

Is there a way to isolate my implementation?

I assume it relates to this code:

exceptiongroup/src/exceptiongroup/_formatting.py

Lines 343 to 360 in 4e2df21

	traceback_exception_original_format = traceback.TracebackException.format
	traceback_exception_original_format_exception_only = (
	traceback.TracebackException.format_exception_only
	)
	traceback_exception_format_syntax_error = getattr(
	traceback.TracebackException, "_format_syntax_error", None
	)
	if sys.excepthook is sys.__excepthook__:
	traceback.TracebackException.__init__ = ( # type: ignore[assignment]
	PatchedTracebackException.__init__
	)
	traceback.TracebackException.format = ( # type: ignore[assignment]
	PatchedTracebackException.format
	)
	traceback.TracebackException.format_exception_only = ( # type: ignore[assignment]
	PatchedTracebackException.format_exception_only
	)
	sys.excepthook = exceptiongroup_excepthook

What can I do about it?

Sorry, I hadn't seen this before. Unfortunately, this is already a big hack, and there is no mechanism with which other libraries could piggyback on exceptiongroup.
