Answer 1

Set the RUBYLIB environment variable for your shell to include the current path .. If you want multiple paths to search from, you can separate each path with :.

export RUBYLIB=.

Test:

$ RUBYLIB='.' ruby -e "p $:"

UPDATE: Put the environment variable settings in your shell's initialization script so that it gets set every time you launch your shell.

Answer 2

$:.unshift File.dirname(__FILE__)

Should add the directory of the file you place the snippet on.

If you want the directory where you are currently working on (where you call the file from) you can do the following:

$:.unshift Dir.getwd
