This project is a work-in-progress and we need your help!

• Report any bugs, typos etc that you find

iSICP is built on the web-worker-interpreter/coding.js library. We use the CodeMirror editor and a custom scheme interpreter.

If you just wish to help port more of SICP to this site, here is how to create an interactive code fragment.

<div id="scheme-times-size">
(* 5 size)
</div>
<script>
prompt("scheme-times-size", ["scheme-define-size"]);
</script>

the div contains the initial text. The second argument to prompt is optional and specifies dependencies.
