Setting RUBYLIB

ruby-talk
1

Hi,

I currently have a project with two files. I want to include one file from the other without specifying the entire path. Here's what I'm trying to do:

File: ./app/control/first.rb
puts "HELLO"

File: ./main.rb
ENV['RUBYLIB'] = "./app"
require 'control/first.rb'

However, it refuses to find the script ('require': No such file to load -- control/first.rb)

When I set RUBYLIB from the (bash) shell, the program runs correctly. How can I set it inside the main ruby program?

Thanks,
-Stu Glaser

The RUBYLIB environment variable is read by the ruby interpreter
only at startup.
Use this:

    $LOAD_PATH.unshift "app"
    require ....

More robust would be to use an absolute path:

    $LOAD_PATH.unshift(File.join(File.dirname(File.expand_path(__FILE__)),
"app"))
    require ...

HTH,

RUBYLIB is for -S option, but not concerned with 'require'.

Sorry, I confused it with RUBYPATH.
