This demo is a JavaScript interpreter. Type some code into |

| 16 |
the text input and press enter to see the results. It uses |

|---|
| 18 |
<a href="../../doc/html/MochiKit/DOM.html">MochiKit.DOM</a> |

to manipulate the display. It also supports waiting for |
|---|
| 20 |
<a href="../../doc/html/MochiKit/Async.html">MochiKit.Async</a> |
|---|
| 21 |
Deferreds via <tt>blockOn(aDeferred)</tt>. |

Notes: |
|---|
| 39 |
<ul> |
|---|
| 40 |
<li> |
|---|
| 41 |
To continue code on the next line, end it with |
|---|
| 42 |
<tt>//</tt> |
|---|
| 43 |
</li> |
|---|
| 44 |
<li> |
|---|
| 45 |
<tt>function name() {}</tt> syntax might not end up in |
|---|
| 46 |
window scope, so use <tt>name = function () {}</tt> |
|---|
| 47 |
syntax instead |
|---|
| 48 |
</li> |
|---|
| 49 |
<li> |
|---|
| 50 |
If you want to stuff something into the output window |
|---|
| 51 |
other than the <tt>repr(...)</tt> of the expression |
|---|
| 52 |
result, use the <tt>writeln(...)</tt> function. |
|---|
| 53 |
It accepts anything that MochiKit.DOM does, so you can |
|---|
| 54 |
even put styled stuff in there! |
|---|
| 55 |
</li> |
|---|
| 56 |
<li> |
|---|
| 57 |
Use <tt>clear()</tt> to clear the interpreter window. |
|---|
| 58 |
</li> |
|---|
| 59 |
<li> |
|---|
| 60 |
You can use <tt>blockOn(aDeferred)</tt> to wait on a |
|---|
| 61 |
Deferred. This expression must be used by itself, so |
|---|
| 62 |
the value must be obtained from <tt>_</tt> or |
|---|
| 63 |
<tt>last_exc</tt>. Typing any expression will |
|---|
| 64 |
cancel the Deferred. |
|---|
| 65 |
</li> |
|---|
| 66 |
<li> |
|---|
| 67 |
Up and down arrow keys work as a rudimentary history |
|---|
| 68 |
</li> |
|---|
| 69 |
<li> |
|---|
| 70 |
<tt>_</tt> is the value of the last expression |
|---|
| 71 |
that was not <tt>undefined</tt>, <tt>last_exc</tt> is |
|---|
| 72 |
the value of the last unhandled exception. |
|---|
| 73 |
