Well rspec for one - but I understand it isn't quite ready for IR yet
- or vice versa. One of the main reason I'm asking is that I'm
starting a project which will be a library, not a stand-alone
application. So I'm wondering about things like dependencies and how
someone would actually use the library. In other words, if my library
depends on another, how does the user using my library actually get
all the dependencies.
I know we're on the bleeding edge here and there a lot of things that
either don't work yet or aren't as elegant as they will be in the
future. I am just trying to avoid going down one path if there is a
better way I'm not aware of.
Thanks for the help!

The thing with gems is that it's going to be quite tricky.. some of
the very useful ones (hpricot for example) depend on C-extensions
and then they need to be ported first to .NET.
At this moment i would try to include them in a lib folder or
something and then require them when I load my script. (read what
merb does ;)) because manually installing doesn't work yet either at
least not when I tried that this morning. At this moment i wouldn't
use IronRuby for anything that has to go into production, that being
said there most of the time there are alternatives in the .NET world
and you can just leverage those.
Out of curiosity which libraries did you want to use?

Thanks for the response. So let me ask you this. If you were to
start building a project and wanted to leverage existing libraries
out there, would you manually install them to your iron ruby install
directory? Or just add them into a gems folder in your project -
like what merb does with frozen gems?

As far as I know you can't use gems yet in IronRuby and that's also
why there is no example with unit tests etc. It can't be done atm.
IronRuby has a minispec framework built in but that isn't as fully
featured as rspec for example.
Basically building stuff with IronRuby is the same as with Ruby
only now you can use everything from .NET too.

As a workaround, use globals instead (eg $x = 42 instead of x = 42).

If you're looking for the "Ruby way" of doing things then there are
plenty of libraries and ruby projects that you can study, for me
personally there is not much difference between programming against
either. If you already know .NET it's just a matter of getting the
hang of Ruby like where and when to use metaprogramming, embracing
hashes etc. For example:
class Member
attr_accessor :name, :age, :marital_status, :children
def initialize(options)
options.each do |key, value|
instance_variable_set "@#{key}", value
end
end
end
member = Member.new :name => "Joe Schmoe", :age =>
27, :marital_status => :married, :children => 2.1
puts member.name
Or you can take existing .NET classes and extend them
module StringExtensions
def to_uri
System::Uri.new self
end
end
require 'mscorlib'
class System::String
include StringExtensions
end
or
System::String.include StringExtensions
Check out ironruby-contrib on github that should hold at least 2
projects that go further than 'hello world'.

I'm wondering if anyone can point me to some good example projects
using IronRuby. Specifically I'm looking for libraries and
projects using some of the things we take for granted with regular
ruby development - rake, gems, rspec, etc. I'm starting a project
of my own and since there isn't a lot of documentation out there
yet I figure looking at other projects is the best way to see how
it's done.
I'm not looking for projects that just use small pieces of IronRuby
- I really want to see how someone would build a library or end-to-
end solution leveraging gems, rake tasks, and unit testing in
IronRuby.
Thanks!
