Thun 0.4.0 Documentation¶
Thun is dialect of Joy written in Python.
Joy is a programming language created by Manfred von Thun that is easy to use and understand and has many other nice properties. This Python package implements an interpreter for a dialect of Joy that attempts to stay very close to the spirit of Joy but does not precisely match the behaviour of the original version(s) written in C. The main difference between Thun and the originals, other than being written in Python, is that it works by the “Continuation-Passing Style”.
Joy is:
I hope that this package is useful in the sense that it provides an additional joy interpreter (the binary in the archive from La Trobe seems to run just fine on my modern Linux machine!) But I also hope that you can read and understand the Python code and play with the implementation itself.
Quick Start¶
Install from PyPI in the usual way:
$ pip install Thun
To start the REPL:
$ python -m joy

Information on the Joy language¶
See the Wikipedia article and Kevin Albrecht’s mirror of Manfred von Thun’s original website for the Joy Programming Language for more information on the Joy language.
The best source (no pun intended) for learning about Joy is the information made available at the website of La Trobe University (see the mirror link above) which contains source code for the original C interpreter, Joy language source code for various functions, and a great deal of fascinating material mostly written by Von Thun on Joy and its deeper facets as well as how to program in it and several interesting aspects. It’s quite a treasure trove.
