Hello everyone. Following a Ruby Quiz posting a while a go, and various prior mentions of Prolog, I ventured off and had an explore on Wikipedia: http://en.wikipedia.org/wiki/Logic_programming Opinion piece: My interest here is that I'm unimpressed with the current state of programming. My feeling is that we've gone off down the wrong route with imperative programming and with OO. Mostly I have this feeling because there are many things that I want to express, which I don't think are particularly complex, but which seem hard to express with programs. I find I need to say a lot more than I feel I should need to. I also believe that our current approaches are much too brittle under change (probably partly because we have to say too much in the first place). Some of the logic ideas seem to line up with things I've been thinking about, but they've actually got something to work ;-) So that got me interested. The question part: So I'd like to have a play about with logic programming, but looking at implementations, my enthusiasm is a bit damped. I was hoping for a lovely graphical environment to start playing with. I'm developing on OS X. I'm not specifically interested in Prolog alone - anything in this area would be good. Can someone suggest tools I should be looking at for getting a feel for the ideas? I've found this: http://www.clip.dia.fi.upm.es/Software/Ciao/ But it's instal from source, which is often a bad beggining for me :-( Thanks in advance, Benjohn

"Logic programming in Ruby: a tiny prolog interpreter and symbolic computation" http://eigenclass.org/hiki.rb?tiny+prolog+in+ruby Sorry if I misunderstood what you were looking for. Kind regards, Chris

It also has Gist, a Graphical Interactive Search Tool. http://www.gecode.org/gecodej/ Bye Libra
