This is a ruby script I (sloppily) cooked up to post daily del.icio.us links to my blog. It requires the Rubilicious library, and (because I'm lazy) is hardcoded to point at my blog.

Change the line

server = XMLRPC::Client.new( "cracker.mocephus.org", "/xmlrpc.php")

So that it points to your blog and your xmlrpc endpoint. Only tested with my Wordpress blog.

An example run would be:

./daily_delicious.rb myblogusername myblogpassword mydelicioususername mydeliciouspassword 1

The last argument is how many days back you'd like to gather links for.

Example post here

#!/usr/local/bin/ruby

require "xmlrpc/client"
require 'rubygems'
require_gem 'Rubilicious'

begin
        unless ARGV.size == 5
                $stderr.puts "Usage: $0 [bloguser] [blogpass] [deluser] [delpass] [days_back]"
                exit -1
        end
        bloguser,blogpass,deluser,delpass,days_back= ARGV

        # Gather Links
        links_date = (Time.now - (86400 * days_back.to_i))
        r = Rubilicious.new(deluser,delpass)
        content = "
"
        r.posts(links_date.strftime("%Y-%m-%d")).each do |link|
                content += "
\"#{link['href']}\">#{link['href']}"
                content += "
"
                content += "
Description: #{link['description']}"
                content += "
#{link['extended']}"
                content += "
Posted: #{link['time']}"
                content += ""
        end
        content += ""

        content += "
Click \"http://del.icio.us/mocephus/\">here for all of my del.icio.us bookmarks."

        newPost['title'] = "del.icio.us bookmarks - #{links_date.strftime('%m/%d/%Y')}"
