Newbie question - undefined method `replace_session_timeout' for main:Object (NoMethodError)

Hi,

I'm a newbie to ruby, and programming really...

I'm trying to write a simple script that will make a small change to a
text file.

Here's the code:

#script for changing the sessionState timeout to 30 minutes

f = File.open('C:\Inetpub\wwwroot\GT\web.config', 'r+')
f.each do |line|
  if /sessionState/ =~line
    offset=line.length
    line=replace_session_timeout line
    f.seek(-offset, IO::SEEK_CUR)
    f.print line
  end
end
f.close

def replace_session_timeout line
  int = /</=~line
  spacer = line[0..int-1]
  result=line.replace spacer + "<sessionState timeout=\"30\"/>\r\n"
end

When I run this script I get the following error:

ruby GT_SessionTimeout_1.rb

GT_SessionTimeout_1.rb:7: undefined method `replace_session_timeout'
for main:Object (NoMethodError)
  from GT_SessionTimeout_1.rb:4:in `each'
  from GT_SessionTimeout_1.rb:4

Exit code: 1

I guess there is something wrong with my method call, but it looks
syntactically correct to me.

I've paged through the pickaxe book and online but, to be honest, I
don't think I understand the problem enough to search well for a
solution.

Any ideas?

Thanks much,
Warren

The Ruby interpreter needs to see the definition of replace_session_timeout before it is called for the first time. Just move the definition above the body of the script.

Wow. That simple. Thanks

The Ruby interpreter needs to see the definition of
