Gturing is a very simple turing machine simulator that takes a simple
|
||
|
|
ASCII file as its input:
|
||
|
|
|
||
|
|
Any empty line or any line beginning with a hash (#) is ignored. In other
|
||
|
|
case, five tokens, each separated by a space, are expected. These are the
|
||
|
|
state number, the expected symbol, the symbol to write, the direction to
|
||
|
|
move, and the new state. Anything following these tokens is ignored.
|
||
|
|
|
||
|
|
Expected symbols and symbols to write can be any printable character.
|
||
|
|
The blank character is represented by the underscore (_). States are
|
||
|
|
integer numbers, starting from 0. The possible directions to move are
|
||
|
|
left and right, represented by 'l' and 'r', respectively.
|
||
|
|
|
||
|
|
The machine starts at state 0 and stops when it cannot find the new
|
||
|
|
state or the new state doesn't expect the read symbol.
