|
||

<content type="html">
|
||
|
|
<p>
|
||
|
|
Total internal revamp: Now a compiler rather than interpreter. Source errors are reported
|
||
|
|
by BASIC line number as well as source line/column.
|
||
|
|
<p>
|
||
|
|
Display defaults to 40 columns, emulates 80-column firmware more accurately. Character output
|
||
|
|
(<code>CHR$()</code>, <code>INVERSE</code>, etc) tweaked to match Apple
|
||
|
|
behavior.
|
||
|
|
<p>
|
||
|
|
Files written via DOS now persist in your browser via <a href="http://dev.w3.org/html5/webstorage/">Web Storage</a>.
|
||
|
|
<p>
|
||
|
|
Floating point and integer overflows are caught rather than propagating infinities and NaNs.
|
||
|
|
<p>
|
||
|
|
<code>DATA</code> statements and <code>INPUT</code> entries parse
|
||
|
|
more accurately as comma delimited, optionally-quoted strings. <code>RE-ENTER?</code>
|
||
|
|
is shown on invalid <code>INPUT</code> (and can be trapped via <code>ONERR</code>)
|
||
|
|
<p>
|
||
|
|
Added <code>HGR2</code> and page-flipping <code>POKE</code> shims, plus a few <code>CALL</code> shims
|
||
|
|
for graphics. Hires graphics are now to a 280x192 bitmap, rather than trying to be sneaky with a 140x192 bitmap.
|
||
|
|
<p>
|
||
|
|
Error codes can be distinguished in <code>ONERR</code> via <code>PEEK(222)</code>.
|
||
|
|
Out-of-memory and stack-overflow conditions reported where possible (this is
|
||
|
|
<a href="http://cautionsingularityahead.blogspot.com/2011/03/stack-overflow-and-out-of-memory-in.html">
|
||
|
|
non-standard across browsers</a>).
|
||
|
|
<p>
|
||
|
|
Tweaked samples that were dependent on language/environment quirks.
|
||
|
|
<p>
|
||
|
|
Updated code editor to (the much improved) <a href="http://codemirror.net/">CodeMirror 2.0</a>. On parse errors,
|
||
|
|
the cursor is moved to the offending line/character.

errors e.g. <code>10 INPUT PRINT</code>
|

</p>

|

|

<p>
|

|

Use <a href="http://flashcanvas.net/">FlashCanvas</a> for older IE versions, instead of
|
||
|
|
<a href="http://excanvas.sourceforge.net/">excanvas</a>, and switch to plotting hires
|

pixels/lines directly rather than relying on canvas scaling and line drawing.

Added compatibility shims for <code>PEEK(78)</code> and <code>PEEK(79)</code>
|
||
|
|
for seeding the random number generator. On a real Apple these are incremented during the input
|
||
|
|
polling loop and are a good source of entropy for seeding a random number generator. In this
|
||
|
|
interpreter, they are simply generated by the JavaScript <code>Math.random()</code> function.

Added lexical highlighting in code editor via <a href="http://codemirror.net">CodeMirror</a>. Note that this only highlights tokens, it does not check statement or expression syntax. It will highlight invalid tokens and unsupported statements.

Mousing over the screen now updates paddle position - try the lo-res painting demo for an example.

used for execution. Hopefully nothing broke - all unit tests still pass.

Tracked down source of IE perf issues when drawing with paddles; when the thumb/stick moves,
|
||
|
|
IE does a relayout/repaint of any content above the paddle in the HTML flow. If I delete the
|

|
|
page header it's silky-smooth. Unfortunately, any text above the screen seems to make it fall
|
||
|
|
off the deep end - so no fix yet without gutting the page.

A bunch of performance tweaks based on IE8's JavaScript profiler. While they look good on paper,
|
||
|
|
they mean diddly-squat to perceived performance. Don't precalc default variable values, avoid DOM
|
||
|
|
changes that are no-ops, and (sigh) don't scan the whole screen looking for <code>FLASH</code>-styled
|
||
|
|
cells - maintain a list instead so perf isn't impacted if there are none.

Expressions are now just-in-time compiled to JavaScript. Screen updates are the real bottleneck, though,
|
||
|
|
so this isn't a big performance boost. Performance comparison (on my 1.73GHz machine) of the lores Mandelbrot set demo:
|
||
|
|
<ul>
|
||
|
|
<li>Google Chrome (V8 JavaScript compiler): 25% faster (21s vs. 27s)</li>
|
||
|
|
<li>Firefox 3: 14% faster (64s vs. 73s)</li>
|
||
|
|
<li>Internet Explorer 8: &lt;1% faster (249s vs. 251s)</li>
|
||
|
|
</ul>
|
||
|
|
So not a huge win except on faster execution engines. But this is just the first step...
