• Progress Bars: A customizable progress bar with adjustable width, characters, and styles.
• Thread Safety: Safe to use in concurrent environments with mutexes.
• Customizable Themes: Use predefined themes or create your own custom spinner themes.

Installation

To install Spinix, use go get:

go get github.com/Kei-K23/spinix

Usage

Spinners

Here’s how to create and use a spinner:

package main

import (
	"time"
	"github.com/Kei-K23/spinix"
)

func main() {
	spinner := spinix.NewSpinner().
		SetSpinnerColor("\033[34m").
		SetMessage("Loading...").
		SetMessageColor("\033[36m").
		SetSpeed(100 * time.Millisecond) // Adjust speed if necessary

	spinner.Start()

	// Simulate some work
	time.Sleep(5 * time.Second)

	spinner.Stop()

    // spinix.NewSpinner() will also create spinner with default properties
    // e.g
    // spinner := spinix.NewSpinner()
	// spinner.Start()
	// time.Sleep(5 * time.Second)
	// spinner.Stop()
}

Progress Bars

Creating and using a progress bar is just as straightforward:

package main

import (
	"time"
	"github.com/Kei-K23/spinix"
)

func main() {
	progressBar := spinix.NewProgressBar().
		SetWidth(50).
		SetColor("\033[32m").
		SetLabel("Progress:")

	progressBar.Start()

	for i := 0; i <= 100; i++ {
		progressBar.Update(i)
		time.Sleep(50 * time.Millisecond) // Simulate work
	}

	progressBar.Stop()

    // spinix.NewProgressBar() will also create progress bar with default properties.
    // e.g
    // progressBar := spinix.NewProgressBar()
    // progressBar.Start()
	// for i := 0; i <= 100; i++ {
	// 	progressBar.Update(i)
	// 	time.Sleep(50 * time.Millisecond) // Simulate work
	// }
	// progressBar.Stop()
}

Customization

Spinners

You can customize the spinner's message, colors, speed, theme and define a custom callback function that will run once the and spinner is completed:

func main() {
	spinner := spinix.NewSpinner().
		SetMessage("Processing...").
		SetMessageColor("\033[33m").
		SetCustomTheme([]string{"▁", "▃", "▄", "▅", "▆", "▇", "█", "▇", "▆", "▅", "▄", "▃"}).
		SetSpinnerColor("\033[31m"). // Red color (you can use every color you want with that format but spinner color will not work with emoji spinner)
		SetSpeed(200 * time.Millisecond).
		SetCallback(func() {
			fmt.Println("The callback function has executed!")
		})

	spinner.Start()
	time.Sleep(2 * time.Second) // Simulate a task
	spinner.Stop()
}

Progress Bars

You can customize the progress bar's message, width, color, appearance and define a custom callback function that will run once the and progress bar is completed:

func main() {
	progressBar := spinix.NewProgressBar().
		SetWidth(60).
		SetBarChar("█").
		SetEmptyChar("░").
		SetBorders("[", "]").
		SetShowPercentage(true).
		SetCallback(func() {
			fmt.Println("The callback function has executed!")
		})

	progressBar.Start()

	for i := 0; i <= 100; i++ {
		progressBar.Update(i)
		time.Sleep(50 * time.Millisecond) // Simulate work
	}

	progressBar.Stop()
}

Use Predefined Spinner and Progress bar

Spinners

You can also use predefined spinner themes that provided by spinix: See all available predefined spinner themes below

func main() {
	spinner := spinix.NewSpinner().
		SetMessage("Processing...").
		SetMessageColor("\033[33m").
		SetTheme(spinix.SpinnerRotatingArrow)

	spinner.Start()

	// Simulate some work
	time.Sleep(5 * time.Second)

	spinner.Stop()
}

Progress Bars

You can use predefined progress bar style that provided by spinix: See all available predefined progress bar styles below

func main() {
	progressBar := spinix.NewProgressBar().
		SetStyle(spinix.PbStyleBasic).
		SetShowPercentage(true)

	progressBar.Start()

	for i := 0; i <= 100; i++ {
		progressBar.Update(i)
		time.Sleep(50 * time.Millisecond) // Simulate work
	}

	progressBar.Stop()
}

	spinner.SetMessage("Loading Data...")
	spinner.Start()
	progressBar.SetWidth(50)
	progressBar.SetColor("\033[36m") // Cyan
	progressBar.Start()

	for i := 0; i <= 100; i++ {
		progressBar.Update(i)
