# == Producing RSS 2.0

[11] Fix | Delete

#

[12] Fix | Delete

# Producing our own RSS feeds is easy as well. Let's make a very basic feed:

[13] Fix | Delete

#

[14] Fix | Delete

# require "rss"

[15] Fix | Delete

#

[16] Fix | Delete

# rss = RSS::Maker.make("2.0") do |maker|

[17] Fix | Delete

# maker.channel.language = "en"

[18] Fix | Delete

# maker.channel.author = "matz"

[19] Fix | Delete

# maker.channel.updated = Time.now.to_s

[20] Fix | Delete

# maker.channel.link = "http://www.ruby-lang.org/en/feeds/news.rss"

[21] Fix | Delete

# maker.channel.title = "Example Feed"

[22] Fix | Delete

# maker.channel.description = "A longer description of my feed."

[23] Fix | Delete

# maker.items.new_item do |item|

[24] Fix | Delete

# item.link = "http://www.ruby-lang.org/en/news/2010/12/25/ruby-1-9-2-p136-is-released/"

[25] Fix | Delete

# item.title = "Ruby 1.9.2-p136 is released"

[26] Fix | Delete

# item.updated = Time.now.to_s

[27] Fix | Delete

# end

[28] Fix | Delete

# end

[29] Fix | Delete

#

[30] Fix | Delete

# puts rss

[31] Fix | Delete

#

[32] Fix | Delete

# As you can see, this is a very Builder-like DSL. This code will spit out an

[33] Fix | Delete

# RSS 2.0 feed with one item. If we needed a second item, we'd make another

[34] Fix | Delete

# block with maker.items.new_item and build a second one.
