Hello, fellow Rubyists! I am creating an [Iron]Ruby project that needs to support several environments (more specifically, WPF, Silverlight, and WinForms - but that's not as important). The following is an actual, concrete example of where I'm stuck: I have to implement a Bitmap class as part of a library, and this class will need to b...
I know alot of Java people have started looking at Scala since it runs on the JVM, and alot of people in the Microsoft world are looking at F#, but what does Ruby have as a natural functional successor? In a pure FP sense Ruby doesn't lack anything, instead it has too much some may say. A functional language forces the programmer to not...
I have several static pages and a couple of dynamic pages. Static pages are under the "Info" controller. Dynamic pages are under "products". I want to access "products" from their :permalink I can only get map.info or map.products to work but not both. ActionController::Routing::Routes.draw do |map| map.resources :products map...
I'm using Test::Unit::TestCase to write some unit tests. Currently, I have a setup function that moves and modifies some fixture files and folders on disk. (This is a necessary evil at the moment.) If a test crashes, the teardown method doesn't get called, leaving files and folders in the way. The next time I run a test, it complains...

For instance, I want the user to create a connection to the api and then be able to query results from subclasses. module ApiWrapper class Connection include HTTParty base_uri '...' def initialize( ...
Using my not-outstanding Google skills, I have not been able to find a decent tutorial on Groovy for Ruby programmers. There are a lot of political pieces (Ruby is great! Groovy is great!) and tiny little contrasts, but I really don't care which is better. I know Ruby (and Java) relatively well, and I'd like to learn Groovy. Would anybo...
I'm trying to parse (in Ruby) what's effectively the UNIX passwd file-format: comma delimiters, with an escape character \ such that anything escaped should be considered literally. I'm trying to use a regular expression for this, but I'm coming up short — even when using Oniguruma for lookahead/lookbehind assertions. Essentially, all o...
I'm saving a bunch of ID's to the session like this. session[:id_group] = 1,2,3,4,5 Because I need to save them to a data base with a form. In that form I have hidden-field : <%= form.text_field :group, :value => session[:id_group].inspect%> I use the inspect so that the value saved to the database gets to be [1,2,3,4,5] and not 1...

In Ruby, I'd like to convert a slash-separate String such as "foo/bar/baz" into ["foo/bar/baz", "foo/bar", "foo"]. I already have solutions a few lines long; I'm looking for an elegant one-liner. It also needs to work for arbitrary numbers of segments (0 and up). ...
Greetings, I'm trying to work out what query is being used to forward people to my website. I'd appreciate it if anyone could tell me what api call I should be looking into. I'm sure this is possible with javascript as well as ruby and php so any technology is fine. Just for learning sake I don't mind know what I should be using for ...
Possible Duplicate: Is it possible to write good and understandable code without any comments? When coding often I hear that if comments are needed then it means that the code is too hard to understand. I agree that code should be readable but often the language itself makes the code hard to follow, because of "plumbing" and s...

I use matching URLs in a part of my code. Now I use regular expressions for this. This is fine, but does not always produces "nice", simply readable patterns. Is there any language defined for matching URLs? It should be like this: http://*.example.com/* so simply wild-cards and things useful for URL would be there. The best would if th...
