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.

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 C:/Program Files (x86)/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2383:in `load' C:/Program Files (x86)/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2383:in `raw_load_rakefile' C:/Program Files (x86)/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2017:in `load_rakefile' C:/Program Files (x86)/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in `standard_exception_handling' C:/Program Files (x86)/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2016:in `load_rakefile' C:/Program Files (x86)/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2000:in `run' C:/Program Files (x86)/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in `standard_exception_handling' C:/Program Files (x86)/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:1998:in `run' C:/Program Files (x86)/IronRuby 1.0v4/lib/ironruby/gems/1.8/gems/rake-0.8.7/bin/rake:31 C:/Program Files (x86)/IronRuby 1.0v4/bin/rake:19:in `load' C:/Program Files (x86)/IronRuby 1.0v4/bin/rake:19 Anyone have any clues?
