1//! # Freya Terminal 🖥️
2//!
3//! Terminal emulator integration for Freya applications.
4//!
5//! This crate provides a way to embed interactive terminal emulators in your Freya applications.
6//! It uses PTY (pseudo-terminal) to spawn shell processes and renders VT100-compatible terminal output
7//! with full 256-color support.
8//!
9//! ## Features
10//!
11//! - **PTY Integration**: Spawn and interact with shell processes
12//! - **VT100 Rendering**: Full terminal emulation with cursor, colors, and text attributes
13//! - **256-Color Support**: ANSI 16 colors, 6x6x6 RGB cube, and 24-level grayscale
14//! - **Keyboard Input**: Handle all standard terminal key sequences
15//! - **Auto-resize**: Terminal automatically resizes based on available space
16//!
17//! ## Basic Usage
18//!
19//! ```rust,no_run
20//! use freya::prelude::*;
21//! use freya_terminal::prelude::*;
22//!
23//! fn main() {
24//! launch(LaunchConfig::new().with_window(WindowConfig::new(app)))
25//! }
26//!
27//! fn app() -> impl IntoElement {
28//! let mut handle = use_state(|| {
29//! let mut cmd = CommandBuilder::new("bash");
30//! cmd.env("TERM", "xterm-256color");
31//! TerminalHandle::new(TerminalId::new(), cmd, None).ok()
32//! });
33//!
34//! let focus = use_focus();
35//!
36//! rect().expanded().background((30, 30, 30)).child(
37//! if let Some(handle) = handle.read().clone() {
38//! rect()
39//! .child(
40//! Terminal::new(handle.clone())
41//! .a11y_id(focus.a11y_id())
42//! .on_mouse_down(move |_| focus.request_focus())
43//! .on_key_down(move |e: Event<KeyboardEventData>| {
44//! if let Some(ch) = e.try_as_str() {
45//! let _ = handle.write(ch.as_bytes());
46//! } else {
47//! let _ = handle.write(match &e.key {
48//! Key::Named(NamedKey::Enter) => b"\n",
49//! Key::Named(NamedKey::Backspace) => &[0x7f],
50//! Key::Named(NamedKey::Tab) => b"\t",
51//! Key::Named(NamedKey::ArrowUp) => b"\x1b[A",
52//! Key::Named(NamedKey::ArrowDown) => b"\x1b[B",
53//! Key::Named(NamedKey::ArrowLeft) => b"\x1b[D",
54//! Key::Named(NamedKey::ArrowRight) => b"\x1b[C",
55//! _ => return,
56//! });
57//! }
58//! }),
59//! )
60//! .expanded()
61//! .into_element()
62//! } else {
63//! "Failed to start Terminal.".into_element()
64//! },
65//! )
66//! }
67//! ```
68//!
69//! ## Handling Terminal Exit
70//!
71//! You can detect when the terminal/PTY closes using `TerminalHandle::closed`:
72//!
73//! ```rust,ignore
74//! use_future(move || async move {
75//! terminal_handle.closed().await;
76//! // Terminal has exited, update UI state
77//! });
78//! ```
79//!
