Termios

Mojo Termios via libc. This is only tested on Mac and will most likely have issues with the Termios struct on linux. 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.

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

from termios.c.terminal import tcgetattr, tcsetattr, tcdrain, FD_STDIN, cc_t, Termios, IGNBRK, OPOST, CREAD, ECHO, TCSADRAIN, TCSANOW
from termios.c.syscalls import read_string_from_fd, read_bytes_from_fd, read_from_stdin
from termios.terminal import get_tty_attributes, set_tty_attributes
from termios.tty import set_control_flags_to_raw_mode, set_tty_to_raw, set_tty_to_cbreak


fn get_key_unix() raises -> String:
    var old_settings = get_tty_attributes(FD_STDIN)
    var status = set_tty_to_raw(int(FD_STDIN))

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

    # restore terminal settings
    var ptr = Pointer.address_of(old_settings)
    var setattr_result = set_tty_attributes(FD_STDIN, TCSADRAIN, ptr)
    return key


fn get_key() raises -> String:
    print("Press c to exit.")
    var k: String = ""

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

    return k


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