## Ruby
- [Rubocop](https://github.com/rubocop-hq/rubocop)

### Rubocop Config file
- `.github/linters/.ruby-lint.yml`
- You can pass multiple rules and overwrite default rules
- File should be located at: `.github/linters/.ruby-lint.yml`
- **Note:** We use the Default **GitHub** Rule set from [Rubocop-GitHub](https://github.com/github/rubocop-github)

### Rubocop disable single line
```ruby
method(argument) # rubocop:disable SomeRule, SomeOtherRule
```

### Rubocop disable code block
```ruby
# rubocop:disable
This is a long line
var="this is some other stuff"
# rubocop:enable
```

### Rubocop disable entire file
If you need to ignore an entire file, you can update the `.github/linters/.ruby-lint.yml` to ignore certain files and locations

```yml
inherit_from:
  - .rubocop_todo.yml
  - .rubocop_app_overrides.yml

inherit_mode:
  merge:
    - Exclude

Rails:
  Enabled: true

AllCops:
  TargetRubyVersion: 2.5.1
  EnabledByDefault: true
  Exclude:
    - 'db/**/*'

# shellcheck disable=SC2059,SC2086
echo "some hot garbage"

echo "stuff"
moreThings()
