I could see this being incredibly useful, there has been tons of code pasting, but it will make things a lot cleaner and simpler being able to check out fully functioning code while discussing the problem with someone.<p>Now all it needs is an embeddable widget and this would take over coding blogs and forums.
Very, very nice. Love it. I agree with paulgb, this is something I never thought I would ever find useful, but I can already see myself sharing code snippets with others.<p>I might be getting greedy, but how about syntax highlighting? Although CodePad is really cool. Bravo! Keep up the great work...
Very cool stuff. How are you keeping the backend secure?<p>You should put up a page of the most popular code samples :) And of course, let people vote them up and down.
<i>"... Codepad.org, a pastebin that executes code ..."</i><p>Very nice. Tried <i>"import this"</i> & <i>"hello world in c"</i>. There is a poll over on arclanguage that asks if users want this type of functionality (hosted arc repl). I was surprised that more didn't want this type of feature to hack with Arc ~ "A hosted repl" : <a href="http://arclanguage.org/item?id=4070" rel="nofollow">http://arclanguage.org/item?id=4070</a>
Really cool. I thought of something related yesterday, which would be a place where people could submit code to get comments and feedback from the community about how they would have coded something differently. It would be useful for both newbies, business people, experienced programmers, web programmers, and people who've known COBOL for 20 years and want to learn about new languages. And, for each program, someone could submit code that does the same thing in a different language, especially web languages. This is really awesome and would facilitate this very easily! A good way to learn the proper way to do something, especially with web languages that may change every major version, is by asking questions of experts in an IRC chat, and then watch them argue amongst each other about the best way to implement something. This would solve that problem by letting people browse, search, or reference a particular post or example or add on to it. I'm thinking of a wiki/social news/forum/code execution app.
How about some JavaScript support. Here's I'll help:<p><pre><code> document.write(eval(inputString));
</code></pre>
Of course that lacks any sort of security measures...
Why not include a prettier editor?<p><a href="http://www.cdolivet.net/editarea/" rel="nofollow">http://www.cdolivet.net/editarea/</a><p>Or maybe open an API so that other people can extend it?
Awesome. Future suggestion (for python), add in some external modules like scipy. Then it would be possible to send examples of some of the more obscure modules. Really nice app.
