Prefix string
Suffix string // If `Mode == Done / Error`, Suffix is not printed
Mode Mode
}
DisplayProps controls the display of the progress bar.
type MultiBar ¶

// contains filtered or unexported fields
}
MultiBar renders multiple progress bars.
func (*MultiBar) AddBar ¶
func (b *MultiBar) AddBar(prefix string) *MultiBarItem
AddBar adds a new bar item. This function is not thread safe. Must be called before render loop is started.
func (*MultiBar) StartRenderLoop ¶
func (b *MultiBar) StartRenderLoop()
StartRenderLoop starts the render loop. This function is thread safe.
func (*MultiBar) StopRenderLoop ¶
func (b *MultiBar) StopRenderLoop()
StopRenderLoop stops the render loop. This function is thread safe.
type MultiBarItem ¶
type MultiBarItem struct {
// contains filtered or unexported fields
}
MultiBarItem controls a bar item inside MultiBar.
func (*MultiBarItem) UpdateDisplay ¶
func (i *MultiBarItem) UpdateDisplay(newDisplay *DisplayProps)
UpdateDisplay updates the display property of this bar item. This function is thread safe.
type SingleBar ¶
type SingleBar struct {
// contains filtered or unexported fields
}
SingleBar renders single progress bar.
Example ¶
package main
import (
"strconv"
"time"
"github.com/pingcap/tiup/pkg/cliutil/progress"
)
func main() {
b := progress.NewSingleBar("Prefix")
b.UpdateDisplay(&progress.DisplayProps{
Prefix: "Prefix",
Suffix: "Suffix",
})
n := 3
go func() {
time.Sleep(time.Second)
for i := 0; i < n; i++ {
b.UpdateDisplay(&progress.DisplayProps{
Prefix: "Prefix" + strconv.Itoa(i),
Suffix: "Suffix" + strconv.Itoa(i),
})
time.Sleep(time.Second)
}
}()
b.StartRenderLoop()
time.Sleep(time.Second * time.Duration(n+1))
b.UpdateDisplay(&progress.DisplayProps{
Mode: progress.ModeDone,
// Mode: progress.ModeError,
Prefix: "Prefix",
})
b.StopRenderLoop()
}
Output:
