I wonder if the project devs have thought of putting an instance of this up for the world? There's a solid version of this for ruby (http://tryruby.hobix.com/) I direct people to when they ask about the language, I'd like to see more "try this programming language on the spot" type setups available, it's a shame I can't host them myself.
"Try this programming language on the spot" with wide open public access is something I've been working on recently. I hope you'll like the results when it's released.
http://codepad.org/ does something like that. It seems handy for trying out small bits of code.
OMG! This is so awesome!
I agree. So much so that back when I first saw it last year, I sought out Steven Hazel (codepad.org's creator), and successfully convinced him to join my startup as co-founder at Sauce Labs. Codepad's tech is uber-cool. :-)
The tryruby website is great, especially the tutorial! Wow! All programming languages should have such tutorial interfaces. ;)
I'm actually working on something that will allow people to write these for whatever programming language. And by working, I mean it's in my bank of things to do.
