Golang的终端进度条：pb。

Installation

go get github.com/cheggaaa/pb

Usage

package main    import (      "github.com/cheggaaa/pb"      "time"  )    func main() {      count := 100000      bar := pb.StartNew(count)      for i := 0; i < count; i++ {          bar.Increment()          time.Sleep(time.Millisecond)      }      bar.FinishPrint("The End!")  }

Result will be like this:

> go run test.go  37158 / 100000 [================>_______________________________] 37.16% 1m11s

// create and start bar  bar := pb.New(myDataLen).SetUnits(pb.U_BYTES)  bar.Start()    // my io.Reader  r := myReader    // my io.Writer  w := myWriter    // create multi writer  writer := io.MultiWriter(w, bar)    // and copy  io.Copy(writer, r)    // show example/copy/copy.go for advanced example

Not like the looks?
