Console Engine

Changelog

This library provides simple features for handling user's input and display for terminal applications.
Besides the user input and display, this library also provides some tools to build standalone "screens" that can be used as simply as printing it.

It uses Termion as main tool for handling the screen and inputs. You don't have to worry about initalizing anything because the lib will handle this for you.

Features

• Build custom terminal display using shapes or text
• Terminal handling with a target frame per seconds
• Keyboard and mouse support
• Terminal resizing support
• You are not interested by keyboard/mouse handling, even terminal handling ? You can still build "screens" to just draw using println!()

Platforms

Works for Linux and possibly Mac (need confirmation).

Windows support will be available as soon as termion will support it See here for more info For now, you can change the cargo.toml termion dependency by this : toml termion = { git = "https://gitlab.redox-os.org/Jezza/termion", branch = "windows-support", package = "termion"} Note: window's input initialization requires the user to first press enter. ConsoleEngine will ask the user to press Enter while inializing.

example usage

ConsoleEngine (managing input & output)

```rust use consoleengine::pixel; use consoleengine::termion::color; use console_engine::termion::event::Key;

fn main() { // initializes a screen of 20x10 characters with a target of 3 frames per second // coordinates will range from [0,0] to [19,9] let mut engine = consoleengine::ConsoleEngine::init(20, 10, 3); let value = 14; // main loop, be aware that you'll have to break it because ctrl+C is captured loop { engine.waitframe(); // wait for next frame + capture inputs engine.clear_screen(); // reset the screen

    engine.line(0, 0, 19, 9, pixel::pxl('#')); // draw a line of '#' from [0,0] to [19,9]
    engine.print(0, 4, format!("Result: {}", value)); // prints some value at [0,4]

    engine.set_pxl(4, 0, pixel::pxl_fg('O', color::Cyan)); // write a majestic cyan 'O' at [4,0]

    if engine.is_key_pressed(Key::Char('q')) { // if the user presses 'q' :
        break; // exits app
    }

    engine.draw(); // draw the screen
}

} ```

Screens (generating output)

```rust use consoleengine::screen; use consoleengine::pixel;

fn main() { // create a screen of 20x11 characters let mut scr = screen::Screen::new(20,11);

// draw some shapes and prints some text
scr.rect(0,0, 19,10,pixel::pxl('#'));
scr.fill_circle(5,5, 3, pixel::pxl('*'));
scr.print(11,4, String::from("Hello,"));
scr.print(11,5, String::from("World!"));

// print the screen to the terminal
println!("{}", scr.to_string());

} ```
