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".
