This cop checks that include, extend and prepend statements appear inside classes and modules, not at the top level, so as to not affect the behavior of Object.

Example:

# bad
include M

class C
end

# bad
extend M

class C
end

# bad
prepend M

class C
end

# good
class C
  include M
end

# good
class C
  extend M
end

# good
class C
  prepend M
end

This cop makes sure that Ruby source files have snake_case names. Ruby scripts (i.e. source files with a shebang in the first line) are ignored.

The cop also ignores .gemspec files, because Bundler recommends using dashes to separate namespaces in nested gems (i.e. bundler-console becomes Bundler::Console). As such, the gemspec is supposed to be named bundler-console.gemspec.

Example:

# bad
lib/layoutManager.rb

anything/usingCamelCase

# good
lib/layout_manager.rb

anything/using_snake_case.rake
