RuboCop::Select

Select file path only executable by RuboCop. Diff RuboCop comes!

You can use rubocop --force-exclusion also.

Usage

Pipe between git diff and rubocop.

$ git diff -z --name-only origin/master..HEAD | xargs -0 bundle exec rubocop-select | xargs rubocop

What is this?

I changed files.

$ git diff --name-only origin/master..HEAD
.rubocop.yml
README.md
Rakefile
lib/rubocop/select/file.rb

I want to run rubocop on changed files.

$ git diff --name-only origin/master..HEAD | xargs rubocop

I don't want to run rubocop with .rubocop.yml, README.md. This is why rubocop-select comes.

$ git diff -z --name-only origin/master..HEAD | xargs -0 bundle exec rubocop-select

Great!

$ git diff -z --name-only origin/master..HEAD | xargs -0 bundle exec rubocop-select| xargs rubocop
