## Description
This layer adds [Scheme](http://www.scheme-reports.org) support to SpaceVim.
The following scheme dialect support has been added:
- [MIT Scheme](https://www.gnu.org/software/mit-scheme/)
- [Chez Scheme](https://cisco.github.io/ChezScheme/)
- [guile](https://www.gnu.org/software/guile/)
## Features
- code runner
- REPL support
## Install
To use this configuration layer, update your custom configuration file with:
```toml
[[layers]]
name = "lang#scheme"
```
## Options
- `scheme_dialect`: specify which scheme dialect is used.
- `scheme_interpreter`: option for setting scheme interperter.
for example:
```toml
[[layers]]
name = 'lang#scheme'
scheme_dialect = 'mit-scheme'
scheme_interpreter = 'C:\Program Files (x86)\MIT-GNU Scheme\bin\mit-scheme.exe'
```
## Key bindings
### Inferior REPL process
Start a `scheme` inferior REPL process with `SPC l s i`.
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 the current 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.
