// // <http://www.attacklab.net/> // // // Wherever possible, Showdown is a straight, line-by-line port // of the Perl version of Markdown. // // This is not a normal parser design; it's basically just a // series of string substitutions. It's hard to read and // maintain this way, but keeping Showdown close to the original // design makes it easier to port new features. // // More importantly, Showdown behaves like markdown.pl in most // edge cases. So web applications can do client-side preview // in Javascript, and then build identical HTML on the server. // // This port needs the new RegExp functionality of ECMA 262, // 3rd Edition (i.e. Javascript 1.5). Most modern web browsers // should do fine. Even with the new regular expression features, // We do a lot of work to emulate Perl's regex functionality. // The tricky changes in this file mostly have the "attacklab:" // label. Major or self-explanatory changes don't. // // Smart diff tools like Araxis Merge will be able to match up // this file with markdown.pl in a useful way. A little tweaking // helps: in a copy of markdown.pl, replace "#" with "//" and // replace "$text" with "text". Be sure to ignore whitespace // and line endings. // // // Showdown usage: // // var text = "Markdown *rocks*."; // // var converter = new Showdown.converter(); // var html = converter.makeHtml(text); // // alert(html); // // Note: move the sample code to the bottom of this // file before uncommenting it. // // // Showdown namespace //
