Subject: [ANN] RSS Parser 0.1.1

Hi,

I released RSS Parser 0.1.1.
  http://raa.ruby-lang.org/project/rss/0.1.1

Changes from 0.1.0 are the following:

  * RSS::Maker.make(version, modules) ->
    RSS::Maker.make(version)

    All modules are available without your specification.

  * Easy some RSS feeds merging.

    #setup_maker was added to RSS::RDF, RSS::RDF::Channel and
    so on. It setups maker object which is a block argument
    of RSS::Maker.make by receiver's object.
    
    For example, The following script merges RSS
    1.0/0.9x/2.0 which are specified as command line
    argument and output merged RSS 1.0. You only change the
    first argument of RSS::Maker.make, that is "1.0", to
    "2.0" if you want to make RSS 2.0.

#!/usr/bin/env ruby

require "rss/maker"

feeds = []
encoding = "UTF-8"

ARGV.each do |fname|
  rss = nil
  f = File.new(fname).read
  begin
    rss = RSS::Parser.parse(f, false)
  rescue RSS::Error
  end
  if rss
    begin
      rss.output_encoding = encoding
    rescue RSS::UnknownConversionMethodError
    end
    feeds << rss
  end
end

rss = RSS::Maker.make("1.0") do |maker|
  maker.encoding = encoding
  maker.channel.about = "http://example.com/blend.rdf"
  maker.channel.title = "blended feeds"
  maker.channel.link = "http://example.com/"
  maker.channel.description = "blended feeds generated by RSS Parser"

  feeds.each do |feed|
    feed.items.each do |item|
      item.setup_maker(maker)
    end
  end
  maker.items.do_sort = true
  # maker.items.max_size = 15
end
puts rss
