Add $LOAD_PATH externally
load-path, ruby
Solution
`RUBYLIB` environment variable is a colon separated list of paths which ruby will prepend to the standard LOAD_PATH. `ruby -I path` on the command line is also the same as `$LOAD_PATH.unshift 'path'` in your code. Ruby will also process options from environment var RUBYOPT.
Problem
I understand that to add a path to $LOAD_PATH just do ``` $LOAD_PATH.unshift(path) ``` But I have to add this line to every program I wrote. Is there anyway to add it to the system level? I tried to search a bit on the startup script for Ruby, but did not find the answer. I tried to add this line to `kernel/common/module.rb`, `ruby_constants.rb`, `loader.rb`,etc. but neither works. In which file should I add this line to? Updates: I am using ubuntu 10.04 and Rubinius. There is no system variable called `RUBYLIB`. Tried creating one but did not work. But I realize I made a mistake, and forgot to add the variable in bash script `.bashrc`. After adding the variable, it all works fine!
