## Description

This layer is for ruby development.

## Installation

### Layer

To use this configuration layer, add `SPLayer 'lang#ruby'` to your custom configuration file.

### Syntax checking && Code formatting

```sh
gem install rubocop

Start a `irb` inferior REPL process with `SPC l s i`. 

Send code to inferior process commands:
