In reference to this question: Ideal ruby project structure I noticed that appname.rb is in lib, and is top level.

I was reading through a little of the Rake source code on Github, and I noticed their project structure is pretty much the same. They have a top level ‘rake.rb’ file in /lib, but I’m not sure what it’s there for.

In The Pickaxe (Programming Ruby 1.9), they show an example of structuring a small project, with pretty much the same directory structure above, but there is no mention of the usage of a top level .rb in /lib.

So, my question is: What exactly is this thing typically used for in a Ruby project?

Sorry if this is a stupid question, I’m sure it is, but I’m relatively new to Ruby. I don’t know that much Ruby-foo right now. 😉

Thanks.

    Usually (and certainly in the example of rake) the appname.rb file is a shortcut to require a lot of other files. If you take a look at that file in the Rake project on GitHub, most of what it does is require files in the lib/rake directory and include modules as necessary. That file is what lets you require 'rake' without having to know what individual files rake needs.
