EasyCurses

A rust crate to smooth over the pain points of working with curses. Because it's based on pancurses, it works equally well with on both windows and unix computers.

Here's a basic demo:

extern crate easycurses;

use easycurses::*;

fn main() {
    let mut easy = EasyCurses::initialize_system();
    easy.set_cursor_visibility(CursorVisibility::Invisible);
    easy.set_echo(false);
    easy.print("Hello world.");
    easy.refresh();
    easy.get_input();
}

Unfortunately when you've got curses active rust's normal panic printing doesn't end up working right. The panic message prints before curses does cleanup, and then it's erased by the cleanup faster than you can read it.

I've got you covered with a wrapper function that does the catch_unwind for you:

extern crate easycurses;

use easycurses::*;

fn main() {
    preserve_panic_message(|easy| {
        easy.set_cursor_visibility(CursorVisibility::Invisible);
        easy.set_echo(false);
        easy.print("Hello world.");
        easy.refresh();
        easy.get_input();
        panic!("oh no");
    }).unwrap_or_else(|e| match e {
        Some(errmsg) => println!("Error Occurred: {}", errmsg),
        None => println!("There was an error, but no error message."),
    });
}
