A simple crate to facilitate input and output within programs, with a set of macros. Example:
use utils::*;
use std::io::Write;
clear!();
addstr!("Input something: ");
addln!("You typed: {}.", getstr!());
getstr!();
down!(10);
right!(20);
addstr!("Went down 10 characters and right 20 characters");
getstr!();
addstr!(0, 10, "Moved to 0, 10 within addstr!");
getstr!();
mv!(0, 20);
addstr!("Moved to 0, 20 with mv!");
getstr!();
down!(20);
addln!("Press enter to clear this line.");
getstr!();
line_up!(2);
clear_line!();
line_down!(2);
addln!("Press enter to clear the entire screen.");
getstr!();
clear!();
Copypaste this into a main.rs for a demonstration of the crate (rust playground doesn't support input for some reason?) Note: Since this uses ANSI escape codes for clear!(), mv!(), etc. it may not work on some terminals/systems.
