Subject: [ruby-core:36842] [Ruby 1.9 - Feature #4824] Provide method Kernel#executed?


Issue #4824 has been updated by Rodrigo Rosenfeld Rosas.


Actually, maybe something like the snippet below would be ideal:

if defined?(__MAIN__) ...

This means __MAIN__ is still a constant, but one defined by the interpreter in some conditional way that is injected only in a single file (the main one).

Feature #4824: Provide method Kernel#executed?
http://redmine.ruby-lang.org/issues/4824

Author: Lazaridis Ilias
Status: Open
Priority: Normal
Assignee: 
Category: core
Target version: 


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.
