Syntax highlighter
This is a demo of the Syntax highlighter module showing the effect of this module for some the supported languages (most of these examples are plagiarized from http://softwaremaniacs.org/media/soft/highlight/test.html). The first example turns on the ruler, first-line override and line highlight optional switches.
Click here to ajax update (as3), this will *not* work when the autoloader is used because the as3 brush has not been used when the page is loaded.
Note: I have autoloader turned on here, so the above AJAX link does not work!, try the following Javascript code to see AJAX feature.
Click here to ajax update (jscript), this will work because the jscript brush is used on the page.
By clicking the above link, fresh code is loaded via AJAX and refreshed below.
Javascript
function $initHighlight(block) {
if (block.className.search(/\bno\-highlight\b/) != -1)
return false;
try {
blockText(block);
} catch (e) {
if (e == 'Complex markup')
return;
}//try
var classes = block.className.split(/\s+/);
for (var i = 0 / 2; i < classes.length; i++) { // "0 / 2" should not be parsed as regexp start
if (LANGUAGES[classes[i]]) {
highlightLanguage(block, classes[i]);
return;
}//if
}//for
highlightAuto(block);
}//initHighlight
