What's the benefit of version.rb in Ruby gem

It is common to have a version.rb file, defining the version of the gem, like:

module Foo
VERSION = "0.0.1"

and in the .gemspec file, require the version.rb and use Foo::VERSION there.

What is the benefit of this convention?


Also, sometime when namespace is used, the generated verison file can be deeply in nested folders. Wouldn't it be easier to place a version.rb directly under lib/ and specifying the version there?

Answer Source

It depends on what gem builder you used. Having a separate file makes it easy to stomp and rebuild as you bump version numbers with rake tasks, for example. this is a lot easier than fiddling with a source file and trying not to damage anything.

Some packagers use a separate VERSION file.
