I need a library to handle JSON objects in Ruby. There are two gems available json and json_pure on http://rubygems.org/search?query=json json_pure is written only in Ruby while json is using C. All I understand is that json is faster because of the usage of C. So is json better for production? Both seem to be easily installed just by ...

I'm digging through some interesting code which I'm convinced is wrong. I wondered whether anyone had a thought as to the syntax the developer was trying to use? Heres' the bogus code: render :nothing => true and return if params[:name].nil? My naive fix alludes to my programming language background: if params[:name].nil? render :...
I have a grid that represents an X, Y matrix, stored as a hash here. Some points on the X Y matrix may have values (as type string), and some may not. A typical grid could look like this: {[9, 5]=>"Alaina", [10, 3]=>"Courtney", [11, 1]=>"Gladys", [8, 7]=>"Alford", [14, 11]=>"Lesley", [17, 2]=>"Lawson", [0, 5]=>"Katrine", [2, 1]=>"Tyra...

Hi, I would like to add some debugs for my simple ruby functions and I wrote a function as below, def debug(&block) varname = block.call.to_s puts "#{varname} = #{eval(varname,block)}" end debug {:x} #prints x = 5 debug {:y} #prints y = 5 I understand that eval is evil. So I have two questions. Is there any way to write that d...
I really can't explain this behavior, notice how after I make a request the class' object id has changed, and therefore my is_a? evaluation returns false. any ideas? I'm not even sure how to debug this. Also, this isn't related to making a request from the command line. The same behavior is exhibited on the web server as well, it's just...
Look at this ruby example: puts ["Dog","Cat","Gates"][1] This will output Cat as ruby allows me to directly access the "anonymous" array created. If I try this in PHP, however: echo array("Dog","Cat,"Gates")[1] This won't work. What is this called, not only concerning arrays but all functions? Where else is it possible? Feel f...

Autotest is supposed to map my tests to a class, I believe. When I have class Foo and class FooTest, autotest should see FooTest and say, "Hey, this test corresponds to the unit Foo, so I'll look for changes there and re-run tests when changes occur." And that works, however... When I have Foo::Bar and Foo::BarTest, autotest doesn't see...
