A lightweight and flexible Python decorator to show a console animation (loading animation) while a function is running. Useful for long-running CLI tasks, data processing, I/O, or just making your tools feel more alive.

---

• Add a console animation with a single line
• Optional start, end, and error messages
• Customizable animation style and speed
• Gracefully handles exceptions
• Works with or without decorator arguments
• Clean terminal output (hides cursor during spin)

---

# or

🚀 Usage

✅ Basic animation (no args)

from console_animation import animate

@animate
def task():
    import time
    time.sleep(3)

This will show a rotating animation while task() runs.

---

⚙️ With Custom Messages

@animate(start="Processing...", loaded="✅ Task complete!", error="❌ Something broke.")
def do_work():
    time.sleep(5)

• start – message shown before animation
• loaded or end – message shown after successful run
• error – message shown if exception occurs

---

🎯 Custom animation and Speed

@animate(spinner="⠋⠙⠚⠞⠖⠦⠴⠲⠳⠓", interval=0.05)
def fancy_task():
    time.sleep(3)

• spinner: any iterable of characters
• interval: time (in seconds) between frames

---

❗ Error Handling

If error is not provided:

• The animation will stop
• Cursor will be restored
• The original exception is raised as-is

If error is set:

• It will be printed
• Full traceback is also printed for debugging

---

🧪 Example Script

from console_animation import animate
import time

@animate(start="Crunching numbers...", loaded="✅ Done!", error="🔥 Failed.")
def math_task():
    time.sleep(3)

@animate
def quick_task():
    time.sleep(1)

@animate(start="Breaking...", error="Oops.")
def will_fail():
    raise RuntimeError("Intentional failure.")

math_task()
quick_task()
will_fail()
