// 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
|
