Is there an OpenSource BASIC interpreter in Ruby / Python?

I want something simple to experiment / hack. I have created many interpreters / compilers for c and I just want something simple. Basic BASIC: D

If you don't know (I did my google search ...) yacc / bison is the only way?

thank

None of those listed in TheFreeCountry are acceptable? None of these are in Python, but I should think that starting with XBLite might be more useful than starting with Yacc / Bison / PLY .

Also, Vb2py may be a better starting position than PLY.



If you must go the PLY route, however, consider the MOLE Basic grammar as a starting point instead of trying to tip your own scratch.

PLY is a great library for building a parser for Python. It has a simple BASIC interpreter as one of its example scripts. You can start there.

I also don't know a basic interpreter under ruby, but with enough time and interest, ruby ​​easily "supports" writing an interpreter for any language you like: Developing an Agile DSL in Ruby . I have to admit that this approach comes with some investment of time. :( There are some links at the end of the presentation for further reading about DSL.

You can also look into the Parrot virtual machine which, according to wikipedia today, has some BASIC support.

miniBasic in ruby ​​is available here . Rockit seems WAY more fun than racc.

There is pybasic (basic python), rockit-minibasic (rubybasic).

To make them able to use the gui, it is necessary to develop extensions with the kiwi and shine gui tools for pybasic and rockit-minibasic respectively and similarly to the prima gui for perlbasic if ever exists.
