Now the we have MyWeb 2.0 (which by the way, is quite cool. I could imagine doing tons of things with it.), it’s time for an update to the Ruby interface to YWS—yahoo-ruby 0.2.

Do cool stuff:

require 'yahoo-ruby.rb'
obj = RelatedTags.new('yahoo-ruby', 'ruby', '', '', '', 1)
obj.parse_results.each { |ele|
        ele.each { |k,v|
                print "#{k} => #{v}\n" if v!=nil
        }
}

# Output
Tag => rails
Frequency => 23
Date => 1120011775

The code’s been lying around for some time (observe the date—June 29), but I didn’t release it assuming there’d be an official release or something. Oh well.

I think I’m gonna make major changes to the code. It works well, mind you. However, I’m not satisfied with the design. Ideally I’d like to simply parse the XSD, and spit out a hash. That’d mean each time a new API comes out, I just have to add another schema location to the existing bunch. And I’m not terribly sure I can do that with REXML. Maybe I’m wrong, though, because, honestly, I haven’s dug into it very deep. Oh yeah, I’m gonna move the project to RubyForge.

It's Ruby, man! You don't have to spit out a hash. You can actually create methods.
A Generic REST web service wrapper is something I've wanted to create for a long time. With Ruby's metaprogramming facilities and ERb, it shouldn't be too difficult. Nobody should ever have to create Ruby wrappers for RESTian services any more. Take that, Java! :D

No. Not for me anyway. Mainly a matter of taste. I'm not eloquent enough to say why. Giving a map to the client of your library isn't really very friendly, ya know :)

Anyway, I don't think providing method-like access should even require metaprogramming. ostruct would be a better choice than a map. But I'd actually prefer a "real object" with "real methods" :)

Honestly, you don't get more of a kick using yahoo_search[3].title than using yahoo_search[3]['title'] ? :D

	You could always forward missing methods to [] - I do that when using libglade and haven't had it bite me yet (Reply to this)(Parent)(Thread)

	You really wouldn't prefer being able to call 'Object#methods' or 'Object#responds_to?' and get something that's useful? I don't know. Maybe it's just something about having a map as the interface that disturbs the object-oriented bigot in me :) (Reply to this)(Parent)(Thread)

	hitchhiker 2005-07-08 01:56 pm UTC (link)
	Hm - at least for glade, that's not been an issue, since the method names correspond to otherwise meaningless identifiers I've assigned to components. Actually, I don't think I've ever had occasion to call #methods from within a ruby script, though I could come up with uses. Good point, though. (Reply to this)(Parent)

	why can't you do an official release? (Reply to this)

	whoa - myweb looks amazingly cool. was it ever slashdotted? the 1.0 version slipped entirely under my radar. (Reply to this)(Thread)

	Don't remember seeing it on Slashdot. It’s a Yahoo! thingie after all. 1.0 didn’t have It; 2.0’s got It. (Reply to this)(Parent)

	It implements a little bit of XSD for the purposes of dealing with WSDL. It may be what you're looking for; or at least a good start. -- ~akk http://therealadam.com (Reply to this)
