## Description

This layer is for Red development.

## Install

### Layer

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

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

## Key bindings

### Inferior REPL process

Start a `red` 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#red"
    repl_command = "red --cli"
```

Send code to inferior process commands:

| Key Bindings | Descriptions                                     |
| ------------ | ------------------------------------------------ |
| `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 |

### Running current script

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