one way to do that is to put a big try/except around your main program,
and display the dialogue box in the except clause:
import traceback
def main():
raise RuntimeError("oops!")
try:
main()
except (KeyboardInterrupt, SystemExit):
raise
except:
print "ERROR", repr(traceback.format_exc())
another approach is to install an exit-handler that uses last_traceback
and friends to generate a traceback:
import atexit, traceback, sys
def postmortem():
if hasattr(sys, "last_traceback"):
print "ERROR", repr(traceback.format_exception(
sys.last_type, sys.last_value, sys.last_traceback
))
atexit.register(postmortem)
def main():
raise RuntimeError("oops!")
main()
the latter is less intrusive, and can be squirreled away in a support
module. also, the original exception is still reported to the console,
as usual.
