BBCode for Ruby on Rails

Question

So I'm putting together a simple forum. I'd like to allow my users limited formatting options and BBCode would be plenty for my users. Knowing that I'm assuredly not the first one to want to use BBCode with RoR I googled but couldn't find a straight forward tutorial on how to create a editor which accepts BBCode nor a way to parse and display BBCode formatted input.

Any help or guides would be appreciated!

Answer 1

Gemfile

gem 'bb-ruby'
# run `bundle`

In the place (haml):

%h1= put_header_string.bbcode_to_html.html_safe
%p= "[b]bold text[/b]".bbcode_to_html.html_safe

Besides a builtins you could also extend your own bbcode as you need. For example:

module BBRuby
  @@tags = @@tags.merge({
      'Email' => [
        /\[email(:.*)?\](.*?)\[\/file\1?\]/mi,
        lambda{ |e| "<span class='email'>#{e[2].gsub('@','<i>(at)</i>')}</span>"},
        'protect email from spam',
        '[email][e-mail][/email]',
        :email
      ],
    })
end

In place

[b]Contact me:[/b][email][e-mail][/email]

Contact me: email(at)test.ru

You should give bb-ruby a try. Its documentation on the web page seems to be very clear and straightforward.
