Cgi = CGI.new causes the script to hang

hi,
i don’t know what i’m doing wrong, but the following code outputs ‘before’ and never outputs ‘after’. it seems to be stuck in CGI.new.
does anyone know what might be the problem here?

···

require ‘cgi’
$stdout.sync = true
puts 'before’
cgi = CGI.new
puts ‘after’

thank you

It's trying to read name=value pairs on standard input.

Use Control-D (^D) on un*x or ^Z (???) on windows, to close the input.

guy already mentioned it’s reading from standard in. one thing that’s useful
for testing is:

~ > cat input
key=value
foo=bar

~ > foo.cgi < input

this should work on windows, *nix, whatever.
