max-py: Python externals for MaxMSP

Embedding Python 2 / 3 in MaxMSP with pybind11

Objects:

[py.eval] converts Max message to string and passes it to Python eval(). Outputs Python object converted to Max message or single atom.

[py.exec] converts Max message to string and runs it with Python exec().

[py.func] binds object to specified Python function ([py.func (class.)function_name] or [py.func module (class.)function_name]). Accepts Max message, outputs Python object converted to Max message or single atom.

[py.module] allows to call functions with [(class.)function_name args...] messages to object [py.module module_name]. Otherwise work same as [py.func]

[py.callback] works with callback_name as argument. Adds function 'callback_name()' to the embedded 'max' module. This new function can be called directly from Python code. When it is called from Python code, outputs its arguments through its outlet. 'callback_name' should be unique for each [py.callback] box.

[py.receive] works the same way as [py.callback] but allows multiple instances with the same callback_name.

Currently supported Python types:

• int, float, str -> Max atom

• list -> Max list

• any other object -> Max symbol containing str(object) value

Embedded 'max' module includes:

• max.post(), max.error() : Max console messages

EXPERIMENTAL/INCOMPLETE object functions

• max.new_object()

• object.message()

• object.inlet_count()

• object.outlet_count()

• object.class_name()

• object.method_names()
