Compiling Ruby through JRuby? Hi! I'm currently building a program which will be mostly standalone, and use little libraries, if at all. If I want to use the project as a library within a Java program, would it be possible to compile it through JRuby? -- Thank you for your brain. -MrZombie ... 4 Aug 2010 01:42

If the block is not given, Ruby adds an implicit block of{|obj| obj} (that is all? <Enumerable.html#M003131> will return true only if none of the collection members are false or nil.)

[].all?{} and [].any?{} Behavior I find the following behavior interesting (so interesting that I modified it), and I would like to hear others' thoughts on the subject: [3].all? {|element| element == 3 } # => true [3].all? {|element| element != 3 } # => false (sanity checks) [].all? {|element| element == 3 } # => true [].all? {|element| ... 29 Jul 2010 18:29
Problem with a lambda not executing immediately Hi, I'm using the paperclip plugin for one of my rails app, but my problem is pure Ruby. I'm not good enough with Ruby and lambdas so I need your advice.
