Took a while, but I worked out a solution:
import sys
import dis
import traceback
import io
def t(frame, event, args):
frame.f_trace_opcodes=True
stack = traceback.extract_stack(frame)
pad = " "*len(stack) + "|"
if event == 'opcode':
with io.StringIO() as out:
dis.disco(frame.f_code, frame.f_lasti, file=out)
lines = out.getvalue().split('\n')
[print(f"{pad}{l}") for l in lines]
elif event == 'call':
print(f"{pad}Calling {frame.f_code}")
elif event == 'return':
print(f"{pad}Returning {args}")
elif event == 'line':
print(f"{pad}Changing line to {frame.f_lineno}")
else:
print(f"{pad}{frame} ({event} - {args})")
print(f"{pad}----------------------------------")
return t
sys.settrace(t)
eval('"-".join([letter for letter in "hello"])')
