Easy rubocop wrapping for git diffs

Nexocop

NOTE: Nexocop is still very young, and some functionality is hardcoded (for example, nexocop current assumes that you are diffing against origin/master).

Nexocop is a thin wrapper around rubocop that filters out offenses that weren't introduced by the current revision (currently only git is supported).

It is packaged to be a drop-in replacement for Rubocop. Nexocop will call rubocop for you, passing the same arguments to it that you invoke nexocop with. This means the API is the same, and for the most part you can take your rubocop cop command and just s/rubocop/nexocop/.

Because nexocop calls out to rubocop to do the work, your existing rubocop config will continue to work fine without changes.

For example, if you use rubocop like this:

bundle exec rubocop

Then nexocop will be used like this:

bundle exec nexocop

Or a fuller example:

bundle exec rubocop --format json -o rubocop.json --format html -o rubocop.html

will be

bundle exec nexocop --format json -o rubocop.json --format html -o rubocop.html

Quick Start

Add nexocop to your Gemfile:

gem 'nexocop', '~> 0.1'

Profit! (see above for usage examples)

Things to improve

These are some ideas for improving the tool, tho it is likely that this will break API compatibility with rubocop. My thought is to use -- to separate Rubocop args and nexocop args. If -- is not present in the arg list, then all the arguments will be passed to rubocop as currently happens.

1. Add support for a -q or --quiet flag
2. Support specifying branches
