Shorter version of Dir [File.join (File.dirname (__ FILE__) "," subdirectory / ** / *. Rb ")]?

Question

This is a bit of a micro-question, but every time I create a stone and need to download all the files under a subdirectory for some kind of reflective purpose (or just a quick and dirty pre-load), I ask myself "Of course, should there be a cleaner path?" Referring to this general diagram:

Dir[File.join(File.dirname(__FILE__), "subdirectory/**/*.rb")].each { |f| require f } 

You must call File.dirname on __FILE__ , which makes it unnecessarily verbose. You cannot use the relative path inside the gem, since you do not know where you are loading from.

What ruble are you using? With ruby ​​1.9 you can use require_relative .

 require_relative 'subdirectory/file1.rb' require_relative 'subdirectory/file2.rb' #... 

But you must know the files. require_relative will not work with all files in a subdirectory. But I would not recommend using such a general reading in a gem. You need to know what you are downloading.

If you really want this, you can use something like this:

 Dir.chdir(File.dirname(__FILE__)){ Dir["**/*.rb"].each { |f| require_relative f } } 

With ruby ​​1.8 this should work:

 Dir.chdir(File.dirname(__FILE__)){ Dir["./**/*.rb"].each { |f| require f } }

As for File.join, there are some things for Windows: File.join creates a path, so the OS can use it. On unix, the path separator is / , in windows \ . But, as you already wrote: ruby ​​understands / , so this does not matter in windows. But what happens if you work with Classic Mac OS? There it is : (see Wikipedia Path_ (calculations) ). So it's better to use join, (or you are using my version of Dir.chdir)
