ttyclock-py 2.0.0

Basically tty-clock but rewritten in Python

ttyclock-py

A Python implementation of the classic tty-clock, a digital clock for your terminal.

What's new in v2.0.0 ?!

Major rewrite. Here's what changed:

Tooling:

• Poetry → uv
• Python 3.8+ → 3.10+
• Added mypy (strict type checking)
• Added ruff (linter)
• Reorganized from src/clock/py/ to src/ttyclock/

Code:

• Split into modules instead of one big file
• Full type hints
• Better architecture

Features:

• 5 fonts (was 1)
• Screensaver mode
• Random colors
• Better date format (now shows day of week)
• Terminal resize handling
• Centered error messages

Breaking:

• Needs Python 3.10+
• Module path changed (but CLI is same)

All CLI arguments work the same. Config format is backwards compatible.

Install

pip install ttyclock-py

Build from source:

git clone https://github.com/elliottophellia/clock.py
cd clock.py
uv build
pipx install dist/ttyclock_py-2.0.0-py3-none-any.whl

Usage

ttyclock-py              # basic
ttyclock-py -c -s        # centered with seconds
ttyclock-py -t -P -d     # 12-hour + AM/PM + date
ttyclock-py -r -R        # screensaver mode with random colors

Options

-c, --center          center it
-s, --seconds         show seconds
-b, --bold            bold text
-t, --twelve          12-hour format
-P, --ampm            show AM/PM (needs -t)
-k, --blink           blink the colon
-u, --utc             use UTC
-d, --date            show date
-r, --screensaver     bouncing screensaver (like DVD logo)
-R, --random-color    random colors when bouncing
-C N                  color (0-7): black/red/green/yellow/blue/magenta/cyan/white
-f FONT               font: block/slim/dot/bold/mini
-x X, -y Y            position
-D DELAY              update delay in seconds (default 0.1)
-S, --save-config     save settings

Quit with q, Q, or ESC.

Fonts

5 fonts available:

• block - default
• slim - narrower
• dot - retro LED look
• bold - thick
• mini - compact

Try them: ttyclock-py -f dot -c

Screensaver

-r makes it bounce around. Add -R for color changes.

ttyclock-py -r -R -s -d

Config

Config location:

• Linux/macOS: ~/.config/ttyclock-py/config.json
• Windows: %LOCALAPPDATA%\ttyclock-py\config.json

{
  "color": "GREEN",
  "font": "block",
  "delay": 0.1,
  "options": {
    "twelve_hour": false,
    "show_seconds": true,
    "bold": false,
    "center": true,
    "blink_colon": false,
    "utc": false,
    "show_date": true,
    "show_ampm": false,
    "screensaver": false,
    "random_color": false
  },
  "position": {"x": 0, "y": 0}
}

Use -S to save current settings or edit the file directly.
