I've been reading the Ruby Programming Language book by Flanagan-Matz Context: Difference between Proc.new and lambda w.r.t return statements The book states that a return within a lambda should not raise a LocalJumpError (since lambdas are akin to method calls). A return in a lambda just exits the lambda - not the method enclosing the...

I'm interested in building a DSL in Ruby for use in parsing microblog updates. Specifically, I thought that I could translate text into a Ruby string in the same way as the Rails gem allows "4.days.ago". I already have regex code that will translate the text @USER_A: give X points to @USER_B for accomplishing some task @USER_B: take Y p...
I have to wait quite long time (comparing to my friends machines) for executing scripts on jRuby, especially when I'm running rake tasks or tests.

How would you check if a file is an image? I'm thinking you could use an method like so: def image?(file) file.to_s.include?(".gif") or file.to_s.include?(".png") or file.to_s.include?(".jpg") end But that might be a little inefficient and not correct. Any ideas? (I'm using the paperclip plugin, btw, but I don't see any methods to ...

When serving up requests which don't run backticked code, everything is fine, however, as soon as my EM code executes any backticked external script, it stops serving requests and stops executing...

I'm writing some scripts in Ruby, and I need to interface with some non-Ruby code via shell commands. I know there are at least 6 different ways of executing shell commands from Ruby, unfortunately, none of these seem to stop execution when a shell command fails. Basically, I'm looking for something that does the equivalent of: set -o...
When writing some rspec today, I came across some unexpected behavior with comparing Date (and Time) instances to nil. Here's a sample using raw ruby (no Rails or other libraries): user@MacBook-Work ~ $ ruby -v ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0] user@MacBook-Work ~ $ irb >> 1 == nil => false >> "string" == nil...
