Markdown Preview for Rails

Unobtrusively add markdown preview to textareas. This gem currently only works in Rails >= 3.1.x with the asset pipeline enabled.

Add the following line to your Gemfile

gem 'md_preview'

For Rails 3.1 and greater, the files will be added to the asset pipeline:

app/assets/javascripts/application.js

//= require md_preview
//= require jquery.elastic # Optional: Include if you want the textareas to fit content

Optionally include the default stylesheet:

app/assets/stylesheets/application.css

/*= require md_preview */

On any textarea, just set the data-preview attribute to true

<textarea data-preview="true"></textarea>
