Or for local development:

$ virtualenv env
$ source env/bin/activate

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

Then:

$ ./fizzbuzz.divspl

Compiling with RPython

divspl is compatible with RPython. 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:

$ bin/divspl fizzbuzz.divspl
