Language workbench written in python3

[Nestor Arocha]

I'm developing a language workbench written in Python. The idea is to create an environment where grammars and translators can interact easily.

any comments, feedback or ideas?

Translator means what precisely?

 

[Ramchandra Apte]

Examples of translators include compilers, assemblers, and

interpreters. They also include implementations like cfront, which

translates from one high-level language to another lower-level

language. (high and low being relative)

Is conversion from Python to C++ possible from this project?

I'll let the OP answer that. I don't know anything about it.

No, it is not currently possible for several reasons:
* current parser implementation is a recursive descent parser. I haven't implemented an LR parser yet, although PLY lexers and parsers are supported.
* Syntax Directed Translator is not fully implemented either.
* Parser Trees are supported, but there is no clear method defined for converting them into ASTs (like antlr grammars)
* Even with AST and SDT support, a Python to C++ translator will require more complex tools and a lot of coding.

This tool is oriented to small DSLs parsing and translation; grammars like Python or C++ are too complex for the current implementation

I was thinking I could use it for my Python to C/C++ converter - py2c @ code.google.com/p/py2c (py2c would love a developer so join and contribute)
