// The following text is included for historical reasons, but should |

// be taken with a pinch of salt; it's not all true anymore. |
|
|
|
// |
|
// 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. |
|
// |
|
|
|
|
|
// |
|
// Usage: |
|
// |
|
// var text = "Markdown *rocks*."; |
|
// |
|
// var converter = new Markdown.Converter(); |
|
// var html = converter.makeHtml(text); |
|
// |
|
// alert(html); |
|
// |
|
// Note: move the sample code to the bottom of this |
|
// file before uncommenting it. |
