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!

When you give a method a block in Ruby (which is really what you''re doing here), and you''ve defined it as a Proc, you need to pass the variable holding the Proc with an ampersand in front of it. This is because while code blocks and Procs conceptually do the same thing, they are not. The ampersand tells Ruby "hey, convert this to a code block for me". -- Will Green http://hotgazpacho.org/ On Tue, Jul 27, 2010 at 2:40 PM, Goode, Troy <Troy.Goode at nreca.coop> wrote:> 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.

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.

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!
