Probably I have mentioned this several times but I am working on a project for visual programming targeting 3d app blender. I am using currently pharo though I am still interested in squeak too and I have decided that in order to communicate with blender python to use a socket bridge. My project is named "Ephestos". Now what was wondering is the following, how difficult it would be to parse smalltalk to python. Ephestos is of course smalltalk , and blender uses python for its addon system. It would be great if extensions made in Ephestos could converted to python addons.
I am already planning to map smalltalk methods to Blender python api call, but I was wondering how easy it would be to parse that code to python.
So far I am aware of OMeta and Petit Parser libraries. What are your suggestions ?
Parsing is the simplest task in such a project, you probably won't even need OMeta or PP since your source language is Smalltalk and there's a pretty usable parser in the system (after all, the Smalltalk to C translation works with it). Generating the Python code is not a parser task, but a code generator task, and you could use the C code generator as a model for that. However, you'd also need to map the semantics from Smalltalk to Python, and no parser will help you with that.
