Actually Steve Hanov's implementation which we're using does have canvas support. You can find it at http://stevehanov.ca/blog/index.php?id=92 . We stripped the graphical parts since they make little sense in our UI. At some point we may a

Really hard to say. We started experimenting with the idea back in March, but didn't start putting fulltime nights into it until August. I'd say a little over a thousand man-hours over the span of 6 months, but I may be well off the mark.

The prompt label is an image, hence it's not copyable. We experimented a bit with various copy-friendly approaches, but couldn't find anything that was cross-browser and did not damage the look/layout we were going for. To share a session,

Currently you can save a replayable session and get a unique link, but this is public. We do have plans to remember history locally (either just as command history or a full-blown session) in the future. The initial relevant issue is at ht

If it uses a JIT internally, it will produce x86 machine code, which is meaningless to us since we aren't emulating the whole machine. If it doesn't, then emscripting it should work.

To add to this, each language has an about link and an engine link (shown at the bottom when you select a language). These will take you to a page describing the language and the interpreter we're using, respectively.

Thanks for trying it out. * The ^W is fixable, but I'm not sure how I personally feel about hijacking fundamental browser shortcuts. We'll look into it though. * Regarding the environment, in general, multi-threading and multi-processing (a

I've spoken a little about the reason we couldn't use GHC among other things, at https://github.com/replit/repl.it/issues/43 . In short, we need an interpreter rather than a compiler or a JIT, and we need the interpreter itself to run in t

Thanks for the report. We're handling input as raw keystrokes for flexibility, so the more advanced features are sometimes not supported. I've opened an issue for it ( https://github.com/replit/jq-console/issues/19 ) in the appropriate repo

You might be hitting the fact that QBasic actually requires keywords to be in capitals. The original IDE did the conversion for you, but repl.it doesn't. We should really be more lenient about those. For now, check the existing examples and

I think ideone and/or your editor converts tabs to 8 spaces. Trying a tab indent followed by an 8-space one raises an error in native IPython for me. In any case, we're using normal CPython compiled to JavaScript, so it's unlikely to change

Most pieces are positioned in the middle of a square. A simple way to recognize the color of the piece and its square is to do a flood fill with a bit of tolerance (say 32/256) from the center pixel. The area covered by the flood fill will
