BlueCloth isn't working with Rails 3

Is BlueCloth compatible with Rails 3? I can't make it work, may开发者_Go百科be someone uses it?

There is supposed to be a helper called 'markdown' available in the views after requiring 'bluecloth', but this doesn't seem to be available.

I'm upgrading an app to rails3 right now and it worked fine for me. I use a helper function called "format" in templates though the code below also provides a markdown function (in rails3 you'll have to use that with raw()). Here's the contents of my [project]/app/helpers/application_helper.rb

module ApplicationHelper
  # Format text for display.                                                                    
  def format(text)
    sanitize(markdown(text))
  end

  # Process text with Markdown.                                                                 
  def markdown(text)
    BlueCloth::new(text).to_html
  end
end

Like a previous poster said, you'll also need

gem 'bluecloth'

in your [project]/Gemfile. My template looks like:

<p><%= format @post.body %></p>

With the markdown function it would be:

<p><%= raw(markdown(@post.body)) %></p>

So I use the format function. Rename the functions however you want.

I've created a fresh Rails 3 app and in the Gemfile I added:

gem 'bluecloth', '>= 2.0.0'

Then opened the console:

ruby-1.8.7-p302 > BlueCloth.new('**hello**').to_html
=> "<p><strong>hello</strong></p>"

So it appears to be working, at least for me.

You could also try Rdiscount which I am not shure but I think is based on the same C library, or at least has similar benchmarks.

You should be more specific in how is it not working: Does it raises an error? Doesn't it renders html? etc...

---

What you could do, not saying it is pretty, is creating an initializer in your rails project and put the following in it:

require 'bluecloth'

class String
 def markdown
   BlueCloth.new(self).to_html
 end
end

This should enable the markdown method on every string object.

I'd suggest switching to RDiscount over BlueCloth. It's a drop in replacement and is better on all counts.
