Keyboard Input

Low-level keyboard input primitives

Quick Start

main.py

from connectonion.tui import getch, read_key

# Read single character
ch = getch()  # Blocks until keypress

# Read key with arrow handling
key = read_key()  # Returns 'up', 'down', etc.

getch

Read single character without waiting for Enter:

main.py

from connectonion.tui import getch

ch = getch()
# Returns: 'a', '1', '\n', etc.

Works on both Unix (termios) and Windows (msvcrt).

read_key

Read key with arrow/escape sequence handling:

main.py

from connectonion.tui import read_key

key = read_key()

Return Values

Input	Returns
`Arrow Up`	`'up'`
`Arrow Down`	`'down'`
`Arrow Left`	`'left'`
`Arrow Right`	`'right'`
`Escape`	`'esc'`
`Enter`	`'\\n'` or `'\\r'`
Regular char	The character

Example: Navigation Loop

main.py

from connectonion.tui import read_key

selected = 0
options = ["Option A", "Option B", "Option C"]

while True:
    key = read_key()

    if key == 'up':
        selected = max(0, selected - 1)
    elif key == 'down':
        selected = min(len(options) - 1, selected + 1)
    elif key == '\n':
        break  # Selected
    elif key == 'esc':
        selected = -1
        break  # Cancelled
