The structure of the code in my gem is as follows: ./ bin/ ai lib/ app.rb app/ # src files templates/ default.txt .etc. The gem loads fine, my problem is that I cannot find the default.txt file in the templates dir from within the code in the app dir when it ... http://readlist.com/lists/ruby-lang.org/ruby-talk/24/120749.html Fri, 16 May 2008 10:21:46 GMT rutema version 0.7.0 has been released! ## DESCRIPTION: rutema is a test execution tool with a twist.

I looked up a couple of Style guides on the net but they seemed to cover only the formatting of code and not what I was looking for. The first is when casting is it preferred to use Integer(x) or x.to_i? Being from a C background the first is more obvious to me as it states that I am converting x to an Integer. The second has ... http://readlist.com/lists/ruby-lang.org/ruby-talk/24/120729.html Fri, 16 May 2008 01:55:54 GMT Sup, fools?

It turned out to be the one thing that everyone agreed on. I think anyone who has done a real project in Ruby has run into this. Is there any way you can get this in 1.9? ... http://readlist.com/lists/ruby-lang.org/ruby-talk/24/120711.html Thu, 15 May 2008 20:53:40 GMT Florian Frank wrote: > Daniel Waite wrote: >> Florian Frank wrote: >>> Don't do this, better use (1..10).sort_by { rand }.

The changes are incompatible and seem fundamental (e.g. enumeration), which seems peculiar given the late date in the evolution of Ruby. Why make these changes now? (At least, trying to mix a handful of needed new modules out of top of tree with 1.8 obviously doesn't work - the ... http://readlist.com/lists/ruby-lang.org/ruby-talk/24/120680.html Thu, 15 May 2008 16:28:16 GMT Hi, I am wondering if it is possible to create a conditionnal sum.
