System portrait / documented flow

01 / pybusySynchronous and async callers use one spinner interface with terminal-safe output.

Diagram routes and groups

Supported caller styles

  • Synchronous use
  • Async-compatible use

Shared terminal feedback

  • Busy indicator
  • TTY-safe output

02 / Problem and response

Add useful progress feedback without a UI framework.

Constraint

CLI tools benefit from progress feedback, but many lightweight Python projects do not need a full interface layer.

Approach

pybusy provides a compact spinner abstraction that works in synchronous and asynchronous execution paths.

03 / Architecture and boundaries

Synchronous and async callers share one small interface.

Minimal Python package surface for clean terminal integration.

Async-friendly behavior without heavy framework coupling.

Package Surface

A lightweight API keeps adoption simple for one-off scripts and internal tools.

Execution Model

Sync and async support share one mental model so callers do not need separate integration strategies.

  • 01

    Terminal behavior is intentionally predictable so the library stays invisible inside larger workflows.

04 / Package surface

A small interface, in use.

Install

pip install pybusy

Usage

from pybusy import busy

with busy("Syncing metadata"):
    run_sync()

05 / Current state and next work

What exists, and what follows.

Published

The published PyPI utility remains intentionally lightweight and has maintained status in the project source.

Next direction

  • Expand polish around terminal formatting and broader workflow examples.

Small utilities become useful when their defaults are easy to trust.
