Implement Ruby’s AppConfig file

5DollarWhiteBox has a cool lib for ruby to utilize Unix style config file, like:

serverID = web01
serverIPAddress = 192.168.1.102

I tried, it works OK. The only problem is one of my settings has a equal sign in it. This parser then screwed up.

myUrl = http://someghing.com?myId=123

So, xml config is the only option for me, and it’s more popular and cross-platform. By using ruby standard lib ‘rexml/document’, the following configuration can be easily parsed out.

conf_file:
<justing>
<rss_feed_url>http://podcast.overseakids.com/justing_history.xml</rss_feed_url>
</justing>

require ‘rexml/document’
doc = REXML::Document.new(File.new(conf_file))
rss_feed_url = doc.elements['justing/rss_feed_url'].text
