A Rake executable script, is this the correct approach

[John Pywtorak]

I humbly come to you, because searching, mostly google, has failed to
produce a reference, or someone who has done this.

We traditionally run Rakefile's using either
$ rake
or
$ rake -f my.rake
etc

what if I wanted an executable script, say myscript, which is really a
rake task file, but runs as though it where run as above.
Attempt 1
#!/usr/bin/env rake
task :default do puts "Hello, Rake!" end
FAILED

Attempt 2
#!/usr/bin/env ruby
task :default do puts "Hello, Rake!" end
Rake::Task[:default].invoke
SUCCESS

So, is the latter really the best way? While it works I worry that rake
is somehow not setup the same way if the this had been run the
traditional way. Thanks

You missed the point and the sha-bang in attempt 1 which was
#!/usr/bin/env rake, not ruby.

I understand what rake is doing, what I want is an executable rake file
without having to explicitly run rake. Thanks

Well, attempt 1 is merely defining the task, the task then has to be run,
which is what's happening in Attempt 2.

When you type `rake` in the command line, what you are really doing is

rake default

Hopefully that explains what's going on.
