Rails - Aug 2006 - escape block using red cloth

Hi all,

Is it possible to configure red cloth to escape a block such as:

------------------------------------------------------------------
Hello, _this_ works *beautifull*

[code lang="ruby"]
def foo
   bar
end
[/code]
------------------------------------------------------------------

The text in the [code] block should not be parsed by Red Cloth''s
to_html
method.

I cannot find it in the docs.

Many regards,

I''d take out the code block, save it in another variable, hand the rest
of
it to Red Cloth''s to_html method and put the variable back in the
string.
That seems as if it should work:
str = "Hello, _this_ works *beautifull*\n\n[code lang=\"ruby\"]\n
def foo\n
  bar\nend\n[/code]"
toredcloth = str.split(/code/)[0]
Red_Cloth::to_html toredcloth
...

I''ve had this situation and ended up doing something very similar: I
base64-encoded the block (leaving the marking tags) before running it
through RedCloth and some of my other conversions and then decoded the
blocks at the end (making sure to still run h() to prevent any harmful
code).

For anyone who''s interesed, I ended up doing this:

require ''syntaxi''

class Posting < ActiveRecord::Base
  has_many :comments
  belongs_to :posting_category

  REGEX = /\[code.*?code\]/m

  # formattes the message using redcloth, colorizes ruby code using
syntax(i)
  def formatted_message
    code_blocks = get_code_blocks(self.message)
    red_clothed = RedCloth.new(message.gsub(REGEX,
''${code_block}'')).to_html

    code_blocks.each { |c|
      c = Syntaxi.new(c).process
      red_clothed.sub!(/\$\{code_block\}/, c)
    }

    red_clothed
  end

  # retrieves code in [code][/code] blocks
  def get_code_blocks(contents)
    code_blocks = []
    code_block = contents.slice(REGEX)
    if (!code_block.nil?)
      code_blocks << code_block
      while code_block = $''.slice(REGEX)
        code_blocks << code_block
      end
    end
    code_blocks
  end

end

This works fine!

Thanks all!
