# Rubocop::DisallowSafeNavigation
The "safe navigation" operator `&.` makes it easier to work with and propagate nil values. This cop will disallow the safe navigation operator.
```ruby
# bad
foo&.bar
a.foo&.bar
```
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'rubocop-disallow_safe_navigation'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install rubocop-disallow_safe_navigation
## Usage
You need to tell RuboCop to load the extension. There are three
ways to do this:
### RuboCop configuration file
Put this into your `.rubocop.yml`.
```
require: rubocop-disallow_safe_navigation
```
Now you can run `rubocop` and it will automatically load the RuboCop
cops together with the standard cops.
### Command line
```bash
rubocop --require rubocop-disallow_safe_navigation
```
### Rake task
```ruby
RuboCop::RakeTask.new do |task|
task.requires << 'rubocop-disallow_safe_navigation'
end
```
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
