MessQ : message queue for quickly trying any idea

Past some time while trying up some set-up based on Message Queue at infrastructure... needed a quick to set-up, localhost friendly, network available Message Queue service to try out ideas.
So here is Mess(age)Q(ueue). Something quickly thrown together. Would work later to get it more performance oriented, good to go with smaller projects.

rss-motor v0.0.4 ~ a rubygem to ease up your RSS interactions

started a new rubygem project 'rss-motor' (http://rubygems.org/gems/rss-motor) to aid all RSS consuming code by providing the entire (or filtered as per choice) of feeds as Array of Hash values per Feed Item.

===============================================
 ||}}  //\  //\ _ ||\/|| ||@|| ~++~ ||@|| ||))
 ||\\ _\\  _\\    ||  || ||_||  ||  ||_|| ||\\
===============================================

I tried it in a new project 'rss-fanatic' (https://github.com/abhishekkr/rss-fanatic) making to help out RSS Feed fanatics collecting required content without pain of browsing/saving/downloading. Though RSS-Fanatic project is just started and shall be usable in some time soon.

Here is just a mini HowTo easily power you code with rss-motor:

First, obviously you'll need to install the gem

$  gem install rss-motor

or if luckily you already have a Gemfile usage, add following lines to it

source "http://rubygems.org"
gem 'rss-motor'


Now, currently available engines from the rss-motor

• simple way of getting all the items as array of key=value
  puts Rss::Motor.rss_items 'http://news.ycombinator.com/rss'

• get an array of items filtered by one or more keywords
  puts "#{Rss::Motor.rss_grep 'http://news.ycombinator.com/rss', ['ruby', 'android']}"

• to filter even the data of content available at >link/< field present in item plus normal filter
  puts "#{Rss::Motor.rss_grep_link 'http://news.ycombinator.com/rss', ['ruby', 'android']}"

now go on, ride your own rss-bikes.....

xml-motor ~ what it is; how & why should you use it

xml-motor ~ what it is; why & how you should use it

Download this article as pdf on what,why,how
http://speakerdeck.com/u/abhishekkr/p/xml-motor-whatwhyhow-this-xml-parsing-rubygem#


or read it all here.....

Late 2011, I started with a new rubygem project for parsing xml, html content.
  @Rubygems: http://rubygems.org/gems/xml-motor
  @GitHub     : https://github.com/abhishekkr/rubygem_xml_motor

Just created it to test out my work at compact, quick & easy xml-parsing algorithm... can see that
  @Slideshare: http://www.slideshare.net/AbhishekKr/xmlmotor

So, currently this is a non-native, completely independent less-than-250 ruby-LOC available as a simple rubygem to be require-d and use in an easy freehand notation and match with any node attributes.

Current Features:

• Has a single method access to parse require xml nodes from content or file. Use it only if you are gonna parse that xml-content once. For using same xml-content more than once, follow the 3-way step mentioned in examples.
• It doesn't depend on presence of any other system library, purely non-native.
• It parses broken or corrupted xml/html content correctly, just for the content it have.
• Can parse results on looking for node-names, attributes of node or both.
• Uses free-freehand notation to retrieve desired xml nodes
  if your xml looks like,
  '<library>...
    <book> <title>ABC</title> <author>CBA</author> </book>...
    <book>
      <title>XYZ</title>
       <authors> <author>XY</author><author>YZ</author> </authors></book>...
  </library>'
  and you look for 'book.author',
  then, you'll get back ['CBA', 'XY', 'YZ'];
  what that means is the child-node could be at any depth in the parent-node.
• Default return mode is without the tags, there is a switch to get the nodes.
  as you'd have seen in above example:
  'CBA' gets sent by default, not 'CBA'
• To filter your nodes on the basis of attributes, single or multiple attributes can be provided.
• These attribute searches can be combined up with freehand node name searches.
• Readme (a bit weird): https://raw.github.com/abhishekkr/rubygem_xml_motor/master/README

Features To Come:

• Work on making it more performance efficient.
• Limit over result-nodes retrieved from start/end of matching nodes.
• Multi-node attribute-based filter for a hierarchical node search.
• Add dev-knows CSS Selector, it's already present using attribute based search... just need to add a mapping method.

EXAMPLES of usage:
example code to try: https://github.com/abhishekkr/axml-motor/tree/master/ruby/examples

• say, you have an xml file 'dummy.xml', with data as
  <dummy>
    <ummy>    <mmy class="sys">non-native</mmy>  </ummy>
    <ummy>
      <mmy class="sys">      <my class="sys" id="mem">compact</my>    </mmy>
    </ummy>
    <mmy type="user">    <my class="usage">easy</my>  </mmy></dummy>
• its available at rubygems.org, install it as
    $ gem install xml-motor
• include it in your ruby code,
    #!/usr/bin/env ruby
    require 'xml-motor'
• get the XML Filename and/or XML data available
    fyl = File.join(File.expand_path(File.dirname __FILE__),'dummy.xml')
    xml = File.open(fyl,'r'){|fr| fr.read }
• One-time XML-Parsing directly from file
    XMLMotor.get_node_from_file(fyl, 'ummy.mmy', 'class="sys"')
       Result: ["non-native", "\n      compact\n    "]
• One-time XML-Parsing directly from content
    XMLMotor.get_node_from_content xml, 'dummy.my', 'class="usage"'
       Result: ["easy"]
    
• Way to go for XML-Parsing for xml node searches
    xsplit = XMLMotor.splitter xml
    xtags  = XMLMotor.indexify xsplit
  
    [] just normal node name based freehand notation to search:
      XMLMotor.xmldata xsplit, xtags, 'dummy.my'
      Result: ["compact", "easy"]
    [] searching for values of required nodes filtered by attribute:
      XMLMotor.xmldata xsplit, xtags, nil, 'class="usage"'
      Result: ["easy"]
  
    [] searching for values of required nodes filtered by freehand tag-name notation & attribute:
      XMLMotor.xmldata xsplit, xtags, 'dummy.my', 'class="usage"'
      Result: ["easy"]
  
    [] searching for values of required nodes filtered by freehand tag-name notation & multiple attributes:
      XMLMotor.xmldata xsplit, xtags, 'dummy.my', ['class="sys"', 'id="mem"']
      Result: ["compact"]
