A proposal for a new tool to be implemented -
It is often the case that developer write Code in Python and then convert to a
C extension module for performance regions.
A C extension module has a lot of boiler plate code - for instance the
Structures required for each class, the functions for Module initialization etc.
My Idea is a simple tool that uses introspection tools to take a Python module
and to generate the relevant boiler plate for the module - including blank
functions for the module classes and for methods. This tool would use type
annotations (if given) to make sensible choices for parameter and attribute
types, including using int and float directly rather than Internal objects
(depending on tool options).
Yep, that's an awesome idea! Are you aware of Cython? You might be
able to make use of that.
Chris, Thank you.
I am aware of Cython but that isn't quite what I had in mind. I want a tool for
a developer who doesn't want to continue to support the Python 'prototype' for
whatever reason, ie where they want a complete conversion to C.
It might even be possible with inspection of the AST to write some of the code
inside the C functions - but that is not for release 0.1 :-)
You may still be able to take advantage of Cython as part of the
process. One thing that's really cool about source code is that,
fundamentally, it's all text... and Python is *great* at manipulating
text files :) It might be that you can write a script that transforms
a Python module into a Cython module, which can then be compiled
as-is, or further processed as needed.
BTW, not sure which list you're intending to discuss this on, so I'm
just replying on the same list you sent this message to.

This might be what you are looking for?
