在終端應用上展示進度條的Go庫：uiprogress

一個Go庫用于在在終端應用上展示進度條。它提供了一套強大的功能并且可以使用簡單的界面進行自定義。

Progress bars improve readability for terminal applications with long outputs by providing a concise feedback loop.

特性

• Multiple Bars: uiprogress can render multiple progress bars that can be tracked concurrently
• Dynamic Addition: Add additional progress bars any time, even after the progress tracking has started
• Prepend and Append Functions: Append or prepend completion percent and time elapsed to the progress bars
• Custom Decorator Functions: Add custom functions around the bar along with helper functions

用法

To start listening for progress bars, calluiprogress.Start()and add a progress bar usinguiprogress.AddBar(total). Update the progress usingbar.Set(n). Full source code for the below example is available at example/simple/simple.go

uiprogress.Start() // start rendering bar := uiprogress.AddBar(100) // Add a new bar // optionally, append and prepend completion and elapsed time bar.AppendCompleted()
bar.PrependElapsed() for i := 1; i <= bar.Total; i++ {
  bar.Set(i)
  time.Sleep(time.Millisecond * 10)
}

This will render the below in the terminal
