Example of Go language implementation of progress bar data processing method in terminal opening

progress bar implements progress bar on the terminal to process data

In Go language, third-party libraries such aspb(progress bar) to implement a progress bar on the terminal to process data. This library can help you display progress information in your terminal more easily.

usepbExample of library to display progress bars for data processing

Install the pb library

First, you need to installpbLibrary:

go get /cheggaaa/pb/v3

Example of progress bar for data processing

Next, use the following code example to implement a progress bar for data processing:

package main
import (
    "fmt"
    "time"
    "/cheggaaa/pb.v1"
)
func main() {
    // Create a progress bar    count := 100 // Total number of data processing    bar := (count)
    // Simulate data processing process    for i := 0; i < count; i++ {
        // Processing data here can be your actual data processing logic        // Here we only simulate a little delay for example        (50 * )
        // Update progress bar        ()
    }
    // End the progress bar and display the completion message    ()
    ("Data processing completed")
}

In this example, we use(count)Created a progress bar wherecountis the total number of data to be processed. Then, we use()Update the progress bar during data processing. Finally, we use()to end the progress bar and display the message after data processing is completed.

Use the fmt package to create a text progress bar to show the progress of data processing

Here is a sample code that demonstrates how to create a basic text progress bar in the terminal to represent the data processing progress:

package main
import (
    "fmt"
    "time"
)
func main() {
    total := 100 // Total data    progressBarWidth := 50
    for i := 0; i <= total; i++ {
        // Calculate progress percentage        progress := (i * progressBarWidth) / total
        // Rendering progress bar        ("\r[")
        for j := 0; j < progressBarWidth; j++ {
            if j <= progress {
                ("=")
            } else {
                (" ")
            }
        }
        ("] %d%%", (i * 100) / total)
        (100 * ) // Simulated data processing delay    }
    ("\nData processing complete.")
}

In this example, we simulate the process of data processing and update the progress bar in the terminal at each step. The length of the progress bar passesprogressBarWidthVariable control, rendering according to the progress of data processing.("\r")Use carriage return characters\rMove the cursor to the beginning of the line to overwrite the previous progress bar and display a new progress.

Note that this is just a basic example, you can customize the progress bar as needed to suit the needs of the actual application. If you need more complex progress bars, you can also consider using third-party libraries such as/schollz/progressbar, it offers more features and customizable options.
