'requiring' a local module...

Sergio Ruiz

i know this is dirt simple, but i am totally not getting it..

i have a file called "syndication.rb" that includes some modules that i
need...

in the same directory, i have a file that says:

require 'syndication/rhapsody'

when i try to run the program, i get:

LoadError: no such file to load â?? syndication/rhapsody

anyone have any ideas?

thanks!

Of course this is wrong. This 'require' loads a file
'syndication/rhapsody.rb'. But you want to load the file
'syndication.rb'.

So change it to:

require 'syndication'

BTW, if you're launching your program not from the directory where it
resides, then loading the module would fail. You'll have to tell ruby to
load files also from the directory in which you program resides:

$:.unshift File.dirname(__FILE__)
require 'syndication'
