I have a ruby app parsing a bunch of URLs from strings:
@text = "a string with a url http://example.com"
@text.split.grep(/http[s]?:\/\/\w/)
@text[0] = "http://example.com"
This works fine ^^
But sometimes the URLs have text before the HTTP:// for example
@text = "What's a spacebar? ...http://example.com"
@text[0] = "...http://ex...
I'm digging around trying to find a good set of tools for creating console applications, as most of the settings I expect to be using Ruby in the coming months won't be webapps, but server-side scripts.
I know of highline, and I do plan on using that for user and possible password prompts, but I know that the Console application world s...
I have a new rails application which I have created under Windows 7 by going into a directory and typing "rails newapp". The creation went fine, and when I access the root page, all is well. However, when I try to access a page that would access the database, I get this:

I'm using Haml from the command-line to do a basic transform of one .haml file to .html, like this:
> haml input.haml output.html
Thing is, this produces single-quotes around attributes in the resulting HTML. So how to I pass in the :attr_wrapper => '"' option from the command-line?
Alternatively, can I just globally set :attr_wrappe...

So the gospel on pulling associated records that you know you're going to use is to use :include because you'll get a join and avoid a whole bunch of extra queries:
Post.all(:include => :comments)

I keep getting Segmentation faults in the rmagick_processor.rb:52 (part of attachment_fu) while trying to run the test suite for community_engine on a fresh ruby app.
I've noticed I have both librmagick-ruby and librmagic-ruby1.8 which are both ImageMagick APIs for Ruby. Should it be just one? If so which?

Hello, I'm using rails 2.3 for a blog app. I'm trying to get caching to work. So far, I've managed to follow along with these tutorials: http://railslab.newrelic.com/2009/01/22/page-caching
I thought everything was working fine. I even managed to get a cachesweeper to work a la the next tutorial in that series.
But I noticed in the dev...

Hi All,
In Ruby, I know that Method#arity will return a value representing the number of arguments accepted by a method, however I do not know why it is called arity. Can anyone provide some insight into why it would exist in such a seemingly random namespace? and, how do you pronounce it?
THX :)

Hello, what's the PHP equivalent of Ruby's "||=" assignment idiom?
The scenario is I want to instantiate an object or array "on demand," and not necessarily when a class is initialized.
I've tried to find this in the PHP docs, but I'm having difficulty finding things I need in there (miss the Ruby).
Thank you!

I have a simple idea for a small web application that I'd like to build out, but it requires syntax highlighting in the same manner that Pastie does. I was wondering if anybody knew what library (jQuery, Prototype, any) was used in the frontend, and/or which (if any) plugins/gems were used in the backend.
For reference, you can find an...
Say I'm writing a mixin module that adds functionality to a third-party class. Obviously some of the methods and instance variables I want to make accessible to the third-party class and its clients. These constitute the public interface of the mixin module.
