## Terminal progress bar for Go
Simple progress bar for console programms.
### Installation
```
go get github.com/cheggaaa/pb
```
### Usage
```Go
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
```
More functions?
```Go
// create bar
bar := pb.New(count)
// refresh info every second (default 200ms)
bar.RefreshRate = time.Second
// show percents (by default already true)
bar.ShowPercent = true
// show bar (by default already true)
bar.ShowBar = true
// no need counters
bar.ShowCounters = false
// show "time left"
bar.ShowTimeLeft = true
// show average speed
bar.ShowSpeed = true
// convert output to readable format (like KB, MB)
bar.Units = pb.U_BYTES
// and start
bar.Start()
```
Want handle progress of io operations?
```Go
// create and start bar
bar := pb.New(myDataLen)
// for output like MB, KB
bar.Units = 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?
```Go
// insert before usage
pb.BarStart = "<"
pb.BarEnd = ">"
pb.Empty = " "
pb.Current = "-"
pb.CurrentN = "."
```
