Can Pagedown turn "\n" into , just like MarkdownSharp's Autonewlines option?

Question

I'm using markdown editor with Pagedown and MarkdownSharp.

There is an option "AutoNewlines" in MarkdownSharp.

I wonder how to do this in Pagedown (http://code.google.com/p/pagedown/).

Thank you!

Answer 1

the first revision of this answer included a rather naive approach which didn't work in most cases.
i ported the AutoNewLines option from MarkDownSharp to PageDown you can download it here http://code.google.com/r/marcdrexel-pagedown/

it should behave exactly as in MarkDownSharp

usage sample:

var converter = Markdown.getSanitizingConverter();
converter.autoNewLine = true;
var editor = new Markdown.Editor(converter);
editor.run();

Answer 2

This is now possible through the postSpanGamut hook provided by the Markdown Converter in Pagedown. This is the code I am using:

function nl2br(text) {

    // Replace new lines with <br/> tags to preserve formatting for users that are 
    // not used to markdown swallowing single line breaks.
    return text.replace(/\n/g, " <br>\n");
}

var converter = new Converter();
converter.hooks.chain("postSpanGamut", nl2br);

It is important to use the postSpanGamut hook rather than a more general preConversion hook as the postSpanGamut only runs on the contents of text blocks and there doesn't not mess up list formatting and other aspects of markdown.
