How can I tell if Rails code is being run via rake or script/generate?

Question

I've got a plugin that is a bit heavy-weight. (Bullet, configured with Growl notifications.) I'd like to not enable it if I'm just running a rake task or a generator, since it's not useful in those situations. Is there any way to tell if that's the case?

Answer 1

It appears that running rake will define a global variable $rakefile, but in my case it gets set to nil; so you're better off just checking if $rakefile has been defined... seeing as __FILE__ and $FILENAME don't get defined to anything special.

$ cat test.rb 
puts(global_variables.include? "$rakefile")
puts __FILE__
puts $FILENAME
$ cat Rakefile 
task :default do
    load 'test.rb'
end
$ ruby test.rb
false
test.rb
-
$ rake
(in /tmp)
true
./test.rb
-

Not sure about script/generator, though.
