+# Multi Progress Bar
+
+[![GoDoc](https://pkg.go.dev/badge/github.com/vbauerster/mpb)](https://pkg.go.dev/github.com/vbauerster/mpb/v7)
+[![Build Status](https://travis-ci.org/vbauerster/mpb.svg?branch=master)](https://travis-ci.org/vbauerster/mpb)
+[![Go Report Card](https://goreportcard.com/badge/github.com/vbauerster/mpb)](https://goreportcard.com/report/github.com/vbauerster/mpb)

+
+**mpb** is a Go lib for rendering progress bars in terminal applications.
+
+## Features
+
+- **Multiple Bars**: Multiple progress bars are supported
+- **Dynamic Total**: Set total while bar is running
+- **Dynamic Add/Remove**: Dynamically add or remove bars
+- **Cancellation**: Cancel whole rendering process
+- **Predefined Decorators**: Elapsed time, [ewma](https://github.com/VividCortex/ewma) based ETA, Percentage, Bytes counter
+- **Decorator's width sync**: Synchronized decorator's width among multiple bars
+
+## Usage
+
+#### [Rendering single bar](_examples/singleBar/main.go)
+
+```go
+package main
+
+import (
+ "math/rand"
+ "time"
+
+ "github.com/vbauerster/mpb/v7"
+ "github.com/vbauerster/mpb/v7/decor"
+)
+
+func main() {
+ // initialize progress container, with custom width
+ p := mpb.New(mpb.WithWidth(64))
+
+ total := 100
+ name := "Single Bar:"
+ // adding a single bar, which will inherit container's width
+ bar := p.Add(int64(total),
+ // progress bar filler with customized style
+ mpb.NewBarFiller(mpb.BarStyle().Lbound("╢").Filler("▌").Tip("▌").Padding("░").Rbound("╟")),
+ mpb.PrependDecorators(
+ // display our name with one space on the right
+ decor.Name(name, decor.WC{W: len(name) + 1, C: decor.DidentRight}),
+ // replace ETA decorator with "done" message, OnComplete event
+ decor.OnComplete(
+ decor.AverageETA(decor.ET_STYLE_GO, decor.WC{W: 4}), "done",
+ ),
+ ),
+ mpb.AppendDecorators(decor.Percentage()),
+ )
+ // simulating some work
+ max := 100 * time.Millisecond
+ for i := 0; i < total; i++ {
+ time.Sleep(time.Duration(rand.Intn(10)+1) * max / 10)
+ bar.Increment()
+ }
+ // wait for our bar to complete and flush
+ p.Wait()
+}
+```
+
+#### [Rendering multiple bars](_examples/multiBars/main.go)
+
+```go
+ var wg sync.WaitGroup
+ // passed &wg will be accounted at p.Wait() call
+ p := mpb.New(mpb.WithWaitGroup(&wg))
+ total, numBars := 100, 3
+ wg.Add(numBars)
+
+ for i := 0; i < numBars; i++ {
+ name := fmt.Sprintf("Bar#%d:", i)
+ bar := p.AddBar(int64(total),
+ mpb.PrependDecorators(
+ // simple name decorator
+ decor.Name(name),
+ // decor.DSyncWidth bit enables column width synchronization
+ decor.Percentage(decor.WCSyncSpace),
+ ),
+ mpb.AppendDecorators(
+ // replace ETA decorator with "done" message, OnComplete event
+ decor.OnComplete(
+ // ETA decorator with ewma age of 60
+ decor.EwmaETA(decor.ET_STYLE_GO, 60), "done",
+ ),
+ ),
+ )
+ // simulating some work
+ go func() {
+ defer wg.Done()
+ rng := rand.New(rand.NewSource(time.Now().UnixNano()))
+ max := 100 * time.Millisecond
+ for i := 0; i < total; i++ {
+ // start variable is solely for EWMA calculation
+ // EWMA's unit of measure is an iteration's duration
+ start := time.Now()
+ time.Sleep(time.Duration(rng.Intn(10)+1) * max / 10)
+ bar.Increment()
+ // we need to call DecoratorEwmaUpdate to fulfill ewma decorator's contract
+ bar.DecoratorEwmaUpdate(time.Since(start))
+ }
+ }()
+ }
+ // Waiting for passed &wg and for all bars to complete and flush
+ p.Wait()
+```
