This is Cat's Eye Technologies' distribution of Thue, an esoteric programming language designed by John Colagioia. Thue is a non-deterministic string-rewriting language, based on a formalism called a semi-Thue system, but also including some programming-oriented features, like input and output.
The specification can be found in the file thue.txt
in the doc
directory.
John's implementation of the language, in C, is in the file thue.c
in the
src
directory, and can, for all intents and purposes, be considered the
reference implementation. There is no Makefile
but an executable can be
built by running the included build.sh
script, which is trivial.
In the src
directory, there are also two other implementation of Thue:
thue.py
, in Python, written by Frédéric van der Planckethue.rb
, in Ruby, written by Chris Pressey
There is an assortment of example Thue programs in the eg
directory. The
credits for these are as follows:
