What every python developer should have in their ~/.pdbrc

.pdbrc

# Enable tab completion

# Sometimes when you do something funky, you may lose your terminal echo. This

import termios, sys                                                             
termios_fd = sys.stdin.fileno()                                                 
termios_echo = termios.tcgetattr(termios_fd)                                    
termios_echo[3] = termios_echo[3] | termios.ECHO                                
termios_result = termios.tcsetattr(termios_fd, termios.TCSADRAIN, termios_echo) 

This doesn't really work as expected...

locals is evaluated at init time so the actual locals wont be visible..
