Thanks for the help everyone! I had been trying multiple variations of the code
I sent, removing/adding asterisks & ampersands and just never stumbled upon the
correct combo. Thanks again for the help!

Specifically, if you do an explicit return (use the return keyword) from a
Proc, that exits the scope in which the Proc is executed. lambdas that return
do not exit the scope in which it was executed.

To pass the body proc into define_task, you need to turn it into a block by
calling &body. I would also recommend using a lambda instead of a proc (due to
return semantics). I'll also be turning my WIX rake tasks into a gem, so there
will be more examples there.

Subject: [Ironruby-core] custom rake task
I was following Derek Bailey’s article from yesterday entitled “How to Build
Custom Rake Tasks; The Right Way”
<http://www.lostechies.com/blogs/derickbailey/archive/2010/07/26/how-to-build-custom-rake-tasks-the-right-way.aspx>
and tried to replicate some of his code in IronRuby. Now I’ve run into a snag
that I’m hoping somebody can help with.
My .rb file looks like so:
require 'rake'
def foo(*args)
body = proc {
puts 'hello world'
}
Rake::Task.define_task(*args, body)
end
foo :bar
task :default => [:bar]
Pretty simple, right? Well, when I run it using rake, I get the following error:
C:\Users\txg0\Desktop>rake -f test1.rb --trace
(in C:/Users/txg0/Desktop)
rake aborted!
syntax error, unexpected IDENTIFIER, expecting AMPERSAND

Anyone have any clues?
