Terminal Modes Guide

You are explaining terminal modes. Follow these steps:

1. Query

The user wants to understand: $ARGUMENTS

2. Read Documentation

Read the terminal modes documentation: skills/terminal-docs/references/06-modes.md

3. Mode Overview

Canonical Mode (Cooked)

• Default mode
• Line-by-line input
• Backspace, line editing works
• Input delivered on Enter

Non-Canonical Mode (Raw)

• Character-by-character input
• No line editing
• Immediate input delivery
• Required for editors, games

Cbreak Mode

• Like raw but keeps signals
• Ctrl+C still works

4. Implementation Patterns

Using stty

stty raw -echo    # Raw mode
stty cooked       # Canonical mode

Using termios (C)

struct termios raw;
tcgetattr(STDIN_FILENO, &raw);
raw.c_lflag &= ~(ICANON | ECHO);
tcsetattr(STDIN_FILENO, TCSAFLUSH, &raw);

Python

import tty, termios
tty.setraw(sys.stdin.fileno())

5. Important Flags

• ICANON - Canonical mode
• ECHO - Echo input
• ISIG - Enable signals
• IXON - Flow control

6. Provide Response

Based on the user's query:

1. Explain the relevant mode
2. Provide code to enter/exit the mode
3. Show proper cleanup patterns
4. Note what features are enabled/disabled
5. Include cross-platform considerations
