Git pre-commit hook integration
overcommit is a fully configurable and
extendable Git commit hook manager. To use RuboCop with overcommit, add the
following to your
PreCommit: RuboCop: enabled: true
To use RuboCop in your
Rakefile add the following:
require 'rubocop/rake_task' RuboCop::RakeTask.new
If you run
rake -T, the following two RuboCop tasks should show up:
$ rake rubocop # Run RuboCop $ rake rubocop:auto_correct # Auto-correct RuboCop offenses
The above will use default values
require 'rubocop/rake_task' desc 'Run RuboCop on the lib directory' RuboCop::RakeTask.new(:rubocop) do |task| task.patterns = ['lib/**/*.rb'] # only show the files with failures task.formatters = ['files'] # don't abort rake on failure task.fail_on_error = false end
