//!
//! ## Tuikit
//! Tuikit is a TUI library for writing terminal UI applications. Highlights:
//!
//! - Thread safe.
//! - Support non-fullscreen mode as well as fullscreen mode.
//! - Support `Alt` keys, mouse events, etc.
//! - Buffering for efficient rendering.
//!
//! Tuikit is modeld after [termbox](https://github.com/nsf/termbox) which views the
//! terminal as a table of fixed-size cells and input being a stream of structured
//! messages.
//!
//! ## Usage
//!
//! In your `Cargo.toml` add the following:
//!
//! ```toml
//! [dependencies]
//! tuikit = "*"
//! ```
//!
//! Here is an example:
//!
//! ```no_run
//! use tuikit::attr::*;
//! use tuikit::term::{Term, TermHeight};
//! use tuikit::event::{Event, Key};
//! use std::cmp::{min, max};
//!
//! fn main() {
//!     let term = Term::with_height(TermHeight::Percent(30)).unwrap();
//!     let mut row = 1;
//!     let mut col = 0;
//!
//!     let _ = term.print(0, 0, "press arrow key to move the text, (q) to quit");
//!     let _ = term.present();
//!
//!     while let Ok(ev) = term.poll_event() {
//!         let _ = term.clear();
//!         let _ = term.print(0, 0, "press arrow key to move the text, (q) to quit");
//!
//!         let (width, height) = term.term_size().unwrap();
//!         match ev {
//!             Event::Key(Key::ESC) | Event::Key(Key::Char('q')) => break,
//!             Event::Key(Key::Up) => row = max(row-1, 1),
//!             Event::Key(Key::Down) => row = min(row+1, height-1),
//!             Event::Key(Key::Left) => col = max(col, 1)-1,
//!             Event::Key(Key::Right) => col = min(col+1, width-1),
//!             _ => {}
//!         }
//!
//!         let attr = Attr{ fg: Color::RED, ..Attr::default() };
//!         let _ = term.print_with_attr(row, col, "Hello World! 你好！今日は。", attr);
//!         let _ = term.set_cursor(row, col);
//!         let _ = term.present();
//!     }
//! }
//! ```
