Hi, But I noticed some locals refer to the last traceback. Consider the following example: The output I get (note It seems like the "Traceback from_exception" is capturing the locals at the time you call it. Is there a way to capture the locals at the time the exception is intercepted by the context manager and supplying those locals to "from_exception"? |

As reference for people from the future: from rich.console import Console
from rich.traceback import Traceback
console = Console()
_failure_list = []
class Manager:
def __init__(self):
pass
def __enter__(self):
return self
def __exit__(self, type, value, traceback):
global _failure_list
_failure_list.append(
Traceback(traceback).from_exception(
exc_type=type,
exc_value=value,
traceback=traceback,
show_locals=True,
extra_lines=8,
)
)
return True
with Manager():
my_var = 2
raise FileNotFoundError
with Manager():
my_var = 3
raise FileNotFoundError
console.print('Failures:')
for failure in _failure_list:
console.print(failure) |

I think you can simplify the line with from_exception. Traceback.from_exception(
...

Rather than save a dict with
ext_typeetc, construct a Traceback() instance which will snapshot the local variables. You can then print those Traceback objects whenever you like.
