## Description
This layer is for [e](http://erights.org/index.html) development.
## Install
To use this configuration layer, update your custom configuration file with:
```toml
[[layers]]
name = "lang#e"
```
## Features
- filetype detection
- syntax highlighting(TODO)
- repl support
- code runner
## Layer options
- `e_interpreter`: set the interpreter of e language.
- `e_jar_path`: set the jar path of `e.jar`.
for example:
```toml
[[layers]]
name = 'lang#e'
e_interpreter = 'D:\Program Files\e\rune.bat'
e_jar_path = 'D:\Program Files\e\e.jar'
```
## Key bindings
### Running current script
To run an e file, you can press `SPC l r` to run the current file without losing focus, and the result will be shown in a runner buffer.
### Inferior REPL process
Start a `rune` 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 |
