Termios

Mojo Termios via libc. This is only tested on Mac and will most likely have issues with the Termios struct on linux. It does not work on Ubuntu 22.04 as of now, so you'll need to update the Termios struct as needed if running on Linux. You would most likely need to change the order of the fields in the struct. If that doesn't work, then the values of the constants may need to be updated too.

Installation

1. First, you'll need to configure your mojoproject.toml file to include my Conda channel. Add "https://repo.prefix.dev/mojo-community" to the list of channels.
2. Next, add termios to your project's dependencies by running magic add termios.
3. Finally, run magic install to install in termios. You should see the .mojopkg files in $CONDA_PREFIX/lib/mojo/.

Will add more later. Here's a basic example from the examples directory.

import termios
from termios import Termios, tcsetattr, tcgetattr, set_raw, STDIN


fn get_key_unix() raises -> String:
    var key: String = ""
    with open("/dev/tty", "r") as stdin:
        var bytes = stdin.read_bytes(1)
        key = chr(int(bytes[0]))

    return key


fn get_key() raises -> String:
    print("Press c to exit.")
    var k: String = ""
    var old_settings = tcgetattr(STDIN)
    _ = set_raw(STDIN)

    while True:
        k = get_key_unix()
        if k == 'c':
            break

    # restore terminal settings
    tcsetattr(STDIN, termios.TCSADRAIN, old_settings)
    print(k)

    return k


fn main() raises:
    print(get_key())
