README
# barely [](https://goreportcard.com/report/reconquest/barely)
Dead simple but yet extensible status bar for displaying interactive progress
for the shell-based tools, written in Go-lang.
# Example
```go
package main
import (
"fmt"
"math/rand"
"os"
"sync"
"sync/atomic"
"time"
"github.com/reconquest/barely"
"github.com/reconquest/loreley"
)
func main() {
format, err := loreley.CompileWithReset(
` {bg 2}{fg 15}{bold} {.Mode} `+
`{bg 253}{fg 0} `+
`{if .Updated}{fg 70}{end}{.Done}{fg 0}/{.Total} `,
nil,
)
if err != nil {
panic(err)
}
var (
bar = barely.NewStatusBar(format.Template)
wg = sync.WaitGroup{}
status = &struct {
Mode string
Total int
Done int64
Updated int64
}{
Mode: "PROCESSING",
Total: 100,
}
)
bar.SetStatus(status)
bar.Render(os.Stderr)
for i := 1; i <= status.Total; i++ {
wg.Add(1)
go func(i int) {
sleep := time.Duration(rand.Intn(i)) * time.Millisecond * 300
time.Sleep(sleep)
atomic.AddInt64(&status.Done, 1)
atomic.AddInt64(&status.Updated, 1)
if i%10 == 0 {
bar.Clear(os.Stderr)
fmt.Printf("go-routine %d done (%s sleep)\n", i, sleep)
}
bar.Render(os.Stderr)
wg.Done()
<-time.After(time.Millisecond * 500)
atomic.AddInt64(&status.Updated, -1)
bar.Render(os.Stderr)
}(i)
}
wg.Wait()
bar.Clear(os.Stderr)
}
```
