DelayViewer

DelayViewer is a Python assistant for showing progress info visually within the shell running a python command with long exposure. This library provides a simple spinner graphic and a stopwatch. The predominant use case is to display progress for sections within a decorated function.

Installation

Use the package manager pip to install delayviewer.

pip install delayviewer

Spinner Usage

from delayviewer.spinner import handle_spinner
import time

@handle_spinner
def test_spinner(spinner=None):
    spinner.start('delaying 5 sec')
    time.sleep(5)
    spinner.stop()

test_spinner()

Stopwatch Usage

from delayviewer.stopwatch import handle_stopwatch
import time

@handle_stopwatch
def test_stopwatch(stopwatch=None):
    stopwatch.start('clocking 5 sec')
    time.sleep(5)
    stopwatch.stop('Finished timing!')

test_stopwatch()

Thanks to several posts on StackOverflow regarding basic Spinner class implementation. Took that concept and generated the Stopwatch class to mimic behavior.
