requiring external libraries directly

Mario Ruiz

12/20/2007 2:48:00 PM

I want to put all the external libraries I'm using in my project in a
folder and require directly from there instead of installing the gem in
ruby.

MyProject folder
ExternalLibraries folder
Watir
rexml
oci8
...
mycode requiring the libraries in ExternalLibraries if it's needed


Is that possible?

Just add following string into your code (before require statements)

$:.unshift File.join(File.dirname(__FILE__), "..", "ExternalLibraries
folder")
require ...

this will add ExternalLibraries folder to the ruby load path.

Suggestion:

Instead of:

File.dirname(__FILE__)

use this:

File.dirname(File.expand_path(__FILE__))

The protects you in case of Dir.chdir.

Don't trim context, we don't know what you're talking about when you
do that.

If you're sourcing the files you want from gems, what's wrong with
using gems? It does everything you want without any extra hassle of
figuring out how to get your load path correct.
