Subject: [ruby-core:36732] [Ruby 1.9 - Feature #4824] Provide method Kernel#executed?


Issue #4824 has been updated by Yukihiro Matsumoto.


I agree providing a method to tell whether it is loaded as a library or is executed as a command is more elegant than '__FILE__ == $0', but I am still afraid #executed? can mean multiple ways so that the name can cause confusion.  We need a better name.

Feature #4824: Provide method Kernel#executed?

The current construct to execute main code looks not very elegant:

if __FILE__ == $0
  my_main()          # call any method or execute any code
end

With a Kernel#executed? method, this would become more elegant:

if executed?
  #do this
  #do that
  my_main()
end

or

main() if executed?

This addition would not break any existent behaviour.
