Hi,

how do I recognize if a ruby file prg.rb was called as a separate program
(from the command line) or was just included using require. Testing ARGV
for being nil doesn't seem to work


######################################################################
# file= prg.rb
######################################################################

if ARGV
  print "called from command line"
end

######################################################################
# file= prg2.rb
######################################################################
require 'prg.rb'

print "now in prg2"

######################################################################

calling

%ruby1.6 prg2.rb

produces

called from command line
now in prg2

and NOT just
now in prg2

So what's wrong, I thought it would be the "way of least suprise" to test
ARGV for being nil in the above situation.

Any suggestions?

Artur
