```Rust
fn welcome(ctx &mut ViewContext) {
ctx.insert((0,0), "Welcome");
}
```
# Robust TUI foundation
Arkham attempts to give a firm foundation for building TUI Apps.
It does not provide a set of widgets or components that can be used.
Instead, it tries to make the process of building terminal interfaces
easy enough that they aren't necessary.
- Keyboard handling
- Terminal modification
- Full screen terminal UIs with _alternate screen_ handling
- Full run loop and rendering engine
- Easy text formatting and styling
- Ergonomic component architecture
- Dependency injection
# Components are simple functions
```Rust
fn my_component(ctx &mut ViewContext) {
ctx.insert((0,0), "Welcome");
}
```
# Easily handle text styling
```Rust
fn my_component(ctx &mut ViewContext) {
ctx.insert(
(0,0),
"Welcome"
.to_runes()
.bg(Color::Blue)
.fg(Color::White),
);
}
```
# Painless dependency injection
```Rust
fn my_component(ctx &mut ViewContext, user: Res<MyUser>) {
ctx.insert(
(0,0),
format!("Hello, {}", user.name),
);
}
```
# Easy keyboard handling
```Rust
fn my_component(ctx &mut ViewContext, kb: Res<Keyboard>) {
if kb.char() == Some('x') {
ctx.insert(
(0,0),
"X marks the spot"
);
}
}
```
