Pattern: Redundant file extension in require

Issue: -

Description

Checks for the presence of superfluous .rb extension in the filename provided to require and require_relative.

Note: If the extension is omitted, Ruby tries adding '.rb', '.so', and so on to the name until found. If the file named cannot be found, a LoadError will be raised. There is an edge case where foo.so file is loaded instead of a LoadError if foo.so file exists when require 'foo.rb' will be changed to require 'foo', but that seems harmless.

Examples

# bad
require 'foo.rb'
require_relative '../foo.rb'

# good
require 'foo'
require 'foo.so'
require_relative '../foo'
require_relative '../foo.so'
