Progress Bar (PBar)

The Progress Bar (PBar) Go library provides basic text progress bar functionality.

Features

• Configurable for progress bar length and characters used to paint the bar
• Multi-threaded to paint independently of the underlying looping process

Import

import github.com/smartystreets/pbar

Usage

progress := pbar.NewPBar(5000) // 5000 is the target count
progress.Start()

... some looping work to do
progress.Update(counter)
... end of loop

progress.Finish()

Options

Specify any number of comma separated options as parameters to NewPBar()

For example:

progress := pbar.NewPBar(5000, pbar.BarLength(25), pbar.RefreshIntervalMilliseconds(750))

Progress Bar Label

Set the label that will be output to the left of the bar.

pbar.BarLabel("Loading index: ")

Progress Bar Length

Set the character length of the actual progress bar (not counting the summary text). Default 50.

pbar.BarLength(25)

Progress Bar Refresh Interval

Set the refresh interval of the progress bar in milliseconds. Default 500ms.

pbar.RefreshIntervalMilliseconds(750)

Progress Bar Graphic Characters

Set the graphic characters used in the progress bar.

pbar.BarLeft('⁅')
pbar.BarRight('⁆')
pbar.BarUncompleted('▭')
pbar.BarCompleted('▬')
