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

Question

I know that I can require all files in a directory using ``` Dir['path/to/files/**/*.rb'].each { |file| require file } ``` However, I'm trying to do that for a gem setup file, like so: ``` class MyGem module NS; end end Dir['lib/my_gem/files/**/*.rb'].each { |file| require file } ``` (where all the files in `lib/my_gem/files` are namespaced under MyGem::NS). With a directory structure that looks like this: ``` lib |-- my_gem | |-- files | | |-- file1.rb | | |-- file2.rb | | |-- file3.rb | | `-- ... (many more) `-- my_gem.rb my_gem.gemspec ``` And, well, the `Dir` command doesn't seem to work when I require my gem in another file, since it seems to look for the file paths at run time in my project root (of whatever project I've required my gem from). How can I require all the files in `lib/my_gem/files` in `lib/my_gem.rb`?

Accepted Answer

Rubygems has a facility called find_files that will allow you to search based anything in the load path:

```
Gem.find_files("my_gem/files/**/*.rb").each { |path| require path }
```
