# `repl` command
The `repl` command starts the Read-Eval-Print-Loop (REPL), an interactive
programming environment for Ralix.
## Usage
```bash
ralix repl
```
### Options
- `--tui`: Use the experimental terminal user interface instead.
## Description
The `repl` command allows you to enter and execute Ralix code interactively.
The result of each expression is printed to the console.
There are two versions of the REPL:
- The terminal user interface (TUI) for a richer interactive experience,
which can be activated with the `--tui` flag.
- The default legacy REPL is a simpler, line-by-line interpreter.
## Examples
To start the default REPL:
```bash
ralix repl
```
To start the TUI REPL:
```bash
ralix repl --tui
```
