cmd2.exceptions

Custom cmd2 exceptions

class cmd2.exceptions.SkipPostcommandHooks

Custom exception class for when a command has a failure bad enough to skip post command hooks, but not bad enough to print the exception to the user.

class cmd2.exceptions.Cmd2ArgparseError

A SkipPostcommandHooks exception for when a command fails to parse its arguments. Normally argparse raises a SystemExit exception in these cases. To avoid stopping the command loop, catch the SystemExit and raise this instead. If you still need to run post command hooks after parsing fails, just return instead of raising an exception.

class cmd2.exceptions.CommandSetRegistrationError

Exception that can be thrown when an error occurs while a CommandSet is being added or removed from a cmd2 application.
