instruction set

category: general [glöplog]
 
Following up on casey reas' talk that 0rel posted earlier; he talked there a bit about how he went on to define his work via abstract methods of constructions/specifications; well here is "instruction set":

http://instructionset.org

Quote:

Every month some instructions appear on instructionset.org.

Instructions may be vague or specific. Your challenge is to write software to carry out the instruction.

You may pick any programming or patching language you wish, and may stretch the definition of 'programming language' and 'software' if you like.

You are encouraged to provide sourcecode under a free license of your choosing, but this is not mandatory.

If you have an idea for an instruction, please suggest it, it will have a high chance of being used.

The first set of instruction is:

Draw a straight line and follow it
"Composition 1960 #10" by La Monte Young consists of the single instruction "draw a straight line and follow it". A fitting minimal starting point to instructionset. Please contribute your implementations.

JSYK.

p.s.: there seems to be a bug in the pouet "code" tag..could not use it with that code..

p.p.s: just got it working so I could not resist posting it when seeing the topic :D

Code: #define STRAIGHT 0 class Thing { public: Thing( int a ) : attribute( a ) {} virtual bool draw() = 0; virtual Thing * follow() = 0; protected: int attribute; }; class Line : public Thing { public: Line( int a ) : Thing( a ) {} virtual bool draw() { // todo return true; } virtual Thing * follow() { // todo return this; } }; int main() { Thing *the = new Line( STRAIGHT ) ; while( the && the->draw() ) { the = the->follow(); } if( the ) delete the; return 0; }
