## Description

This layer is for ruby development.

## Install

### Layer

To use this configuration layer, update custom configuration file with:

```toml
[[layers]]
  name = "lang#ruby"
```

### Syntax checking && Code formatting

To enable syntax checking and code formatting in spacevim, you need to install [rubocop](https://github.com/bbatsov/rubocop).

```sh
gem install rubocop
```


## Key bindings

### Inferior REPL process

Start a `irb` inferior REPL process with `SPC l s i`. You may change the REPL command by layer option `repl_command`. For example, if you want to use `pry`, load this layer via:

```toml
[[layers]]
    name = "lang#ruby"
    repl_command = "pry"
```

however, if the executable is not on your $PATH, then you need to specify a complete file path.

```toml
[[layers]]
    name = "lang#ruby"
    repl_command = "/NOT/IN/YOUR/PATH/rubocop"
```
Send code to inferior process commands:

| Key Binding | Description                                      |
| ----------- | ------------------------------------------------ |
| `SPC l s b` | send buffer and keep code buffer focused         |
| `SPC l s l` | send line and keep code buffer focused           |
| `SPC l s s` | send selection text and keep code buffer focused |

### RuboCop

| Key Binding | Description                                |
| ----------- | ------------------------------------------ |
| `SPC l c f` | Runs RuboCop on the currently visited file |

### Running current script

To running a ruby script, you can press `SPC l r` to run current file without loss focus, and the result will be shown in a runner buffer.
