В GDB есть
возможность писать pretty-printers на python.
Python
import gdb
class MoneyPrinter:
def __init__(self, val):
self.val = val
def to_string(self):
return 'Money: ' + str(self.val['amount']*0.01)
def lookup_function (val):
if str(val.type) == 'Money':
return MoneyPrinter(val)
return None
gdb.pretty_printers.append(lookup_function)
>gdb money.exe
