_invocationError ( self,  msg )

Write msg and usage to stderr if interactive, otherwise re-raise

_run ( self )

Override this in subclasses to implement desired behavior

getCommandParent ( self )

Get or create a component to be used as the subcommand's parent

getSubcommand (
        self,
        executable,
        **kw,
        )

Return a ICmdLineApp with our environment as its defaults

Any IExecutable may be supplied as the basis for creating the ICmdLineApp. NotImplementedError is raised if the supplied object is not an IExecutable.

isInteractive ( self )

True if stdin is a terminal

run ( self )

Run the command

runMain ( cls )

Allow this command to be used as a console_scripts entry point

If you want to make a command class into a command that's installable via setuptools, just add something like this to your setup():

            entry_points = {
                'console_scripts': [
                    'some_cmd = some.module:MyCmdClass.runMain'
                ]
            }

This will create a some_cmd command line app that invokes your command class, when you run "setup.py develop", or someone installs your package.

showHelp ( self )

Display usage message on stderr
