# Disabling linters and rules
If you find you need to ignore certain errors and warnings, you will need to know the format to disable the linter rules.  
Below is examples and documentation for each language and the various methods to disable.

--------------------------------------------------------------------------------

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

### Rubocop Config file
- `.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 `.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:
