thue: a C++ implementation of the Thue language

Abstract

This is a C++ project of a command-line processor of John Colagiola’s Thue programming language.

Synopsis

thue [-cdlnr] [-S U] [-s N] FILE

thue [-h | --help]

thue [-V | --version]

Description

The program reads and processes the Thue code in FILE; it reads the input from stdin and prints the output in stdout. By default it follows the convention on newlines in the code proposed by Laurent Vogel.

Options

-c

leave CR at EOL as is

-d

enable the debug print

-l

enable the Left mode: priority given to the leftmost match

-n

disable the feature to print a newline by rules of form ...::=~

-r

enable the Right mode; priority given to the rightmost match

-S U

specify U as a random seed

-s N

stop after N steps at most

-h, --help

print the help

-V, --version

print the version

Examples

See the test code in files of name test/*.t.

test/incr.t

read a binary number, increment it, and print the result

test/quine.t

a Quine

test/seq.t

print an initial segment of the Thue-Morse sequence
