Example

use std::io;
use terminfo::{capability as cap, Database};

fn main() {
	let info = Database::from_env().unwrap();

	if let Some(cap::MaxColors(n)) = info.get::<cap::MaxColors>() {
		println!("The terminal supports {} colors.", n);
	} else {
		println!("The terminal does not support colors, what year is this?");
	}

	if let Some(flash) = info.get::<cap::FlashScreen>() {
		flash.expand().to(io::stdout()).unwrap();
	} else {
		println!("FLASH GORDON!");
	}

	info.get::<cap::SetAForeground>().unwrap().expand().color(2).to(io::stdout()).unwrap();
	info.get::<cap::SetABackground>().unwrap().expand().color(4).to(io::stdout()).unwrap();
	println!("SUP");
	info.get::<cap::ExitAttributeMode>().unwrap().expand().to(io::stdout()).unwrap();
}

Packaging and Distributing

For all terminals but windows consoles, this library depends on a non-hashed (for now) terminfo database being present. For example, on Debian derivitives, you should depend on ncurses-term; on Arch Linux, you depend on ncurses; and on MinGW, you should depend on mingw32-terminfo.

Unfortunately, if you're using a non-windows console on Windows (e.g. MinGW, Cygwin, Git Bash), you'll need to set the TERMINFO environment variable to point to the directory containing the terminfo database.
