Ruby – Using `Require`

Please note that your example can be better written as

require File.expand_path('../lib/nirvana.rb', __FILE__)

Because File::expand_path takes an optional second parameter (Directory string).

Many authors also transfer the lib directory to $LOAD_PATH before executing the binary, so that local files can be loaded before attempting to load any installed gems.

I’m editing a gem, which has the usual require command, pointing to the loaded gem (the gem I’m talking about is called nirvana, and the file contains require’navana’, require’navana /shell’ and so on).

When I use the application’s bin file (/mypath/nirvana/bin/nirvana), the require’nirvana’ command I want to write in it points to The files in the local fork of the gem (the files I’m editing), I don’t want to load the original Nirvana gemstone, it is installed together with the classic gem installation.

I don’t want to use all the’ nirvana’ command substitution

require File.dirname(File.expand_path(__FILE__)) +'/../lib/nirvana.rb'

… …This will solve my problem, but it’s ugly! Is there a way to not load the nirvana gem and make require’nirvana’ to load my libraries (maybe add them in $LOAD_PATH …)?

If you use gems binary executable to do this, then you should only need’nirvana.rb’ once. So this line only needs to appear once . It is common to see it appear in these files.
