Subject: Re: Add custom rules to redcloth/textile how?

Here is all the code implementing one of the default rules.

To create custom rules would be simple:

class RedCloth
    HYPERLINK = '(\S+?)([^\w\s/;=\?]*?)(?=\s|<|$)'

    TEXTILE_REFS_RE =  /(^ *)\[([^\n]+?)\](#{HYPERLINK})(?=\s|$)/

    def refs_textile( text )
        text.gsub!( TEXTILE_REFS_RE ) do |m|
            @urlrefs ||= {} # in RedCloth code, initialized in
initialize, but here I am giving an example of how to extend it

            flag, url = $~[2..3]
            @urlrefs[flag.downcase] = [url, nil]
            nil
        end
    end
end

textile_rules = [:refs_textile, :block_textile_table, :block_textile_lists,
                   :block_textile_prefix, :inline_textile_image,
:inline_textile_link,
                   :inline_textile_code, :inline_textile_span, :glyphs_textile]


redclothvar.to_html(textile_rules)

From here, figuring how to add a rule is really simple.

Define a method in class RedCloth with some RegExp action in it, call
#to_html passing an array which is a copy of the textile_rules array
in #to_html but with your rule added (array sets precedence, so it
counts where your rule is).


Reading _why's code is a pleasure, you should try it once.

Careful: It might blow your mind and send you flying in a three headed
truck with a bouncy marmoset. Specifically, beware of Camping. That is
code on a level that might get those of us with less self confidence
to decide that perhaps shoemaking is a more befitting career.
