I want to build a site where the user can enter text and format it in Markdown. The reason I’d like a Javascript solution is because I want to display a live preview, just like on StackOverflow.
My site is not targeted at developers, however, so an editor control would be ideal.
I gather that on StackOverflow, the WMD editor is being used.
A quick search on Google also turns up Showdown library, which I think is actually being used by WMD.
Are there any other options? Are WMD/Showdown great tools already? What have been your experiences with the different options?
If you’re not averse to using Ajax to generate the live preview, then another option is markItUp!. markItUp! is a universal markup-editor, and very flexible. It does provide an easy way of creating a markup editor, but unlike WMD, it doesn’t provide its own live preview.
I used markItUp!, along with a simple JSP (using MarkdownJ) for one of my open-source projects (a Markdown plugin for Roller). If you’re using another server-side technology, replace that simple JSP as appropriate.
I actually starting using this before I came across WMD. I’d agree, WMD is great, but has only just been open-sourced and is, at this stage, more difficult to customize the behavior of.
