An implementation of a FizzBuzz DSL using rply <https://github.com/alex/rply>_.

Description

divspl is an interpreter for the DIVSPL DSL (Dustin Ingram's Very Special Programming Language Domain Specific Language), which is used for implementing FizzBuzz-like programs. For more information, see http://promptworks.com/blog/the-fastest-fizzbuzz-in-the-west.

Installation

$ pip install divspl

Or for local development::

$ virtualenv env
$ source env/bin/activate
$ python setup.py install

Usage

$ divspl [filename]

Where::

filename            A *.divspl filename to execute

Example

Use the interpreter to execute valid DIVSPL code::

$ divspl fizzbuzz.divspl

Or use it as a shebang::

#!env/bin/divspl
1...15
fizz=3
buzz=5

Then::

$ ./fizzbuzz.divspl

Compiling with RPython

divspl is compatible with RPython <https://rpython.readthedocs.io>__. To compile::

$ pip install rply
$ mkdir -p pypy
$ wget https://bitbucket.org/pypy/pypy/get/default.tar.bz2
$ tar -xvvf default.tar.bz2 -C pypy --strip-components=1
$ mkdir -p bin
$ python pypy/rpython/bin/rpython --output=bin/divspl divspl/target.py

You now have a compiled divspl binary in ./bin, which you can use as follows::
