How can I run Ruby specs and/or tests in MacVim without locking up MacVim?
About 6 months ago I switched from TextMate to MacVim for all of my development work, which primarily consists of coding in Ruby, Ruby on Rails and JavaScript. With TextMate, whenever I needed to run a spec or a test, I could just command+R on the test or spec file and another window would open and the results would be displayed with t...

How is event-driven programming done?
My question is pretty simple: how is event-driven programming actually achieved? To elaborate: I have a Rails application, every time a user makes a change on the website, the model writes that "change" to a text file (as JSON.) What I'd like to do is hook an IRC bot to that "event." (the creation/modification of the text file.) How i...
How can I get click events to work when chaining elements in Watir?
I am attempting to set up some UI testing in Watir for our web application. I'm running into trouble getting the click events to propagate. We are using EXTJS to make tabs, which are spans in the resulting html. If I select a span like this it works: span1 = @browswer.span(:text=>"Tab Name") span1.click The trouble is when I have...
Bit banging in ruby
I want to create a bit, that will contain security permissions for a given user. In c#, I would do this by creating an enumeration, and then I would do some bit banging on the binary value, by anding '&&' to see if it results in a TRUE value. How can I do this best in Ruby? ...
Can't get RDoc to suppress cross-references for a specific word
I'm using the jeweler gem when developing new gems. As part of the skeleton, it sets up a set of RDoc related rake tasks - the main one being rake rdoc. As far as I can tell from the Rakefile, this task uses the rake/rdoctask library to generate HTML documentation from my RDoc comments. It tries intelligently to make references to class...

Rails 3, Custom Actions, and HTML request methods
I don't really understand the pro's and con's of using "post" vs "get" vs "put" requests, on custom controller actions, and whether to use links or forms/buttons. So let's say I have a simple to-do list with tasks, and a tasks controller, and I want a "complete" action where I find a specific task in the db and update it's status attri...
Bundler: Trace and check dependencies in bundled ruby gems
Bundler will automatically install any dependencies for the specified gems, it doesn't however output which dependencies map to which gems in the standard output. That information is useful when one of the dependencies fails the installation. Is there a way to set bundler to be more verbose and inform about the dependencies while instal...
How is it that find_by_id, etc. work on an ActiveRecord array?
Forgive me if I've got my terminology wrong; I am still quite new to Ruby and Rails. For school I am working on an RoR project as part of a team. I was pair programming with a teammate, who actually happens to be experienced in RoR; and I wrote something like the following: d = self.deliverables.find_all_by_lifecycle_id(self.lifecycle_...

Is there an elegant way to test if one instance method is an alias for another?
In a unit test I need to test whether alias methods defined by alias_method have been properly defined. I could simply use the same tests on the aliases used for their originals, but I'm wondering whether there's a more definitive or efficient solution. For instance, is there a way to 1) dereference a method alias and return its original...
