# ElementTui
An Elixir library to create terminal user interfaces (tui), using [termbox2](https://github.com/termbox/termbox2) under the hood. Elementtui provides the basic building blocks for a TUI. There is a companion library available with more complicated [components](https://codeberg.org/edwinvanl/elementtui_components). Code examples are available in a separate [repository](https://codeberg.org/edwinvanl/elementtui_examples).
## Installation
The package can be installed by adding `elementtui` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:elementtui, "~> 0.5"}
]
end
```
## Usage
There are some simple examples available on [codeberg](https://codeberg.org/edwinvanl/elementtui_examples) that should help you get started. Also see the documentation on [hexdocs](https://hexdocs.pm/elementtui/api-reference.html).
Minimal `hello world` example:
```elixir
ElementTui.run_loop(
fn _, ev -> case ev do
{:key, _, _, ?q} ->
{:halt, nil}
_ ->
ElementTui.Element.text("Hello World")
|> ElementTui.render(5, 5, 100, 1)
ElementTui.present()
{:cont, nil}
end
end,
nil,
timeout: 1000
)
```
Note that when starting your own project you need to make sure elixir/erlang does not listen for input, by setting [-noinput](https://codeberg.org/edwinvanl/elementtui_examples/src/branch/main/mix.exs#L14) in the `mix.exs` file.
## Examples
