How to 'require' all files from a directory and its sub-directories (Ruby)?

To require all the files, there is a special gem which does an amazing job. It's require_all but don't install the lastest one.

Install

gem install require_all -v 1.5.0

It provides two beautiful methods require_all() and require_rel()! For require_rel, paths are relative to the caller rather than the current working directory

How to require all files in a directory, in a gem?

What's a good way to require a whole directory tree in Rails?

autoload_paths and friends work only if the given files, or files in the given directories, are named according to the rails naming conventiion.

e.g. if a file some_class.rb is given to autoload_paths, it expcects the file to declare a class SomeClass, and sets up some magic to make any reference to SomeClass load that file on-the-fly.

So if you want to have it only load each of your files as they are needed, then you will have to name your files accordingly, and have one file per class.

If you are happy to load all of the files in a directory tree when rails starts, you can do this:

Dir.glob("/path/to/my/lib/**/*.rb").each { |f| require f }

The above will read every .rb file in /path/to/my/lib, and any directories under it.

Get names of all files from a folder with Ruby
