usage

environment

environment ( name,  default=None )

Get data from the current environment. If the default is True or False, then presume that we're only interested in the existence or non-existence of the environment variable.

expand

expand (
        _data,
        _globals=None,
        _argv=None,
        _prefix=DEFAULT_PREFIX,
        _pseudo=None,
        _options=None,
        **_locals,
        )

Do an atomic expansion of the given source data, creating and shutting down an interpreter dedicated to the task. The sys.stdout object is saved off and then replaced before this function returns.

info

info ( table )

invoke

invoke ( args )

Run a standalone instance of an EmPy interpeter.

Exceptions
Exceptions	Error, "prefix must be single-character string" ValueError, "-b only makes sense with -o or -a arguments"

main

main ()

usage

usage ( verbose=True )

Print usage information.
