Placing the code

Place your code on the page and surround it with <pre> tag. Set name attribute to code and class attribute to one of the language aliases you wish to use.

<pre name="code">
... some code here ...
</pre>

NOTE: One important thing to watch out for is opening triangular bracket <. It must be replaced with an HTML equivalent of < in all cases. Failure to do won’t break the page, but might break the source code displayed.

An alternative to <pre> is to use <textarea> tag. There are no problems with < character in that case. The main problem is that it doesn’t look as good as <pre> tag if for some reason JavaScript didn’t work (in RSS feed for example).

<textarea name="code" cols="60" rows="10">
... some code here ...
</textarea>

Extended configuration

There’s a way to pass a few configuration options to the code block. It’s done via colon separated arguments.

<pre name="code">
... some code here ...
</pre>

Making it work

Finally, to get the whole thing to render properly on the page, you have to add JavaScript to the page.

<link type="text/css" rel="stylesheet" href="css/SyntaxHighlighter.css"></link>
<script language="javascript" src="js/shCore.js"></script>
<script language="javascript" src="js/shBrushCSharp.js"></script>
<script language="javascript" src="js/shBrushXml.js"></script>
<script language="javascript">
dp.SyntaxHighlighter.ClipboardSwf = '/flash/clipboard.swf';
dp.SyntaxHighlighter.HighlightAll('code');
</script>

For optimal result, place this code at the very end of your page. Check HighlightAll for more details about the function.

How to fix Firefox 3 Memory Leak problem

Recently, I have very big problem with my Firefox browser. Few minutes after starting of Firefox application, my Firefox become too slow for surfing, all open applications freeze for two or three seconds after every my click. I noticed that Firefox.exe take up a big part of my computer memory. After reading several forums on the net, I find how to fix this “Firefox memory leak” problem.

Just follow these simple steps to get your Firefox memory usage under control. The solution was in ”about:config” Firefox hidden configuration options.

  1. Get the main configuration screen by putting “about:config” in the browser’s address bar.
  2. Right click on the page and choose New then Integer and create an integer called “browser.cache.memory.capacity”. Set it to a low number (I use 16384 – that means 15MB). This controls how many kilobytes of memory are used for the browser’s cache.
  3. In the Filter of “about:config” page (top of the page) put “browser.cache.disk.capacity”. Set “browser.cache.disk.capacity” (right click – Modify) to between 5000 or 15000 (I use 15000). For example: if you have 128MB to 512M use 5000, if you have 512BM to 1GB of RAM use 15000. This controls how many kilobytes of memory are used for the browser’s cache.
  4. Configure Firefox to swap memory to disk when minimized. In the Filter of “about:config” page (top of the page) put “config.trim_on_minimize”, Right click on the page and choose New then Boolean and create an boolean called “config.trim_on_minimize”. Set it to true. This mean – when you minimize the firefox window it will free up memory.
  5. In the Filter of “about:config” page (top of the page) put “network.prefetch-next”. Set “network.prefetch-next” to false. Network link prefetch will download all pages with the rel=”prefetch” tag, with false you avoid that downloading.
  6. In the Filter of “about:config” page (top of the page) put “browser.sessionhistory.max_total_viewers”. Set it to low number. I set it to 6. This controls how many pages of history are kept in the back/forward buttons.

Restart Firefox and that’s it! Now, your Firefox and your computer will be much faster and you are ready for faster surfing. Enjoy!
