How to turn a require FILE + 'file.rb' into require 'file'?

Question

I have this at the top of the file:

parser_spec.rb:

require File.dirname(__FILE__) + '/parser.rb'

Which has a class inside:

parser.rb:

class Scraper
  def scrape_department(file)

Both files are in the rails/project folder.

How to do it so that I can include that file by just doing require 'parser'?

If you are using Rails and this file is in the lib directory, you might simply load all your libs file using `config.autoload_paths += %W(#{config.root}/lib)` in `config/application.rb` — Pierre-Louis Gottfrois, Aug 16 '13 at 07:21

File.dirname(__FILE__)

Just means to look for the file in the directory of the caller.

Try using

require_relative 'parser'

By the way, I would suggest renaming your file scraper.rb since this is the name of your class inside that file.

Yes, I renamed it scraper.rb. But I followed your suggestion and I got `/home/alex/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- scraper (LoadError) from /home/alex/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/rubyg`. Both files are in the rails/project folder. – alexchenco Aug 16 '13 at 06:42
According to the documentation here http://www.ruby-doc.org/core-2.0/Kernel.html#method-i-require_relative, the file path cannot be determined – Pierre-Louis Gottfrois Aug 16 '13 at 07:19

I think you are looking for require_relative:

require_relative 'parser.rb'

From the docs:

Ruby tries to load the library ... relative to the requiring file’s path.
