package main

	"github.com/gookit/color"
)

func main() {
	// quick use like fmt.Print*
	color.Red.Println("Simple to use color")
	color.Green.Print("Simple to use color")
	color.Cyan.Printf("Simple to use %s\n", "color")
	color.Yellow.Printf("Simple to use %s\n", "color")

	// use like func
	red := color.FgRed.Render
	green := color.FgGreen.Render
	fmt.Printf("%s line %s library\n", red("Command"), green("color"))

	// custom color
	color.New(color.FgWhite, color.BgBlack).Println("custom color style")

	// can also:
	color.Style{color.FgCyan, color.OpBold}.Println("custom color style")

	// internal theme/style:
	color.Info.Tips("message")
	color.Info.Prompt("message")
	color.Info.Println("message")
	color.Warn.Println("message")
	color.Error.Println("message")

	// use style tag
	color.Print("<suc>he</><comment>llo</>, <cyan>wel</><red>come</>\n")

// Only use background color
color.BgRed.Printf("Simple to use %s\n", "color")

// Full custom: foreground, background, option
myStyle := color.New(color.FgWhite, color.BgBlack, color.OpBold)
myStyle.Println("custom color style")

// can also:
color.Style{color.FgCyan, color.OpBold}.Println("custom color style")

custom set console settings:

// set console color
color.Set(color.FgCyan)

// print message
fmt.Print("message")

color.Println("<suc>hello</>")
color.Println("<error>hello</>")

color.Tag("info").Printf("%s style text", "info")
color.Tag("info").Println("info style text")

256-color usage

Set the foreground or background color

color.C256(val uint8, isBg ...bool) Color256

c := color.C256(132) // fg color
c.Println("message")
c.Printf("format %s", "message")

c := color.C256(132, true) // bg color
c.Println("message")
c.Printf("format %s", "message")

Use a 256-color style

Can be used to set foreground and background colors at the same time.

color.S256(fgAndBg ...uint8) *Style256

s := color.S256(32, 203)
s.Println("message")
s.Printf("format %s", "message")

Run demo: go run ./_examples/color256.go

Use RGB color

Set the foreground or background color

color.RGB(r, g, b uint8, isBg ...bool) RGBColor

c := color.RGB(30,144,255) // fg color
c.Println("message")
c.Printf("format %s", "message")

c := color.RGB(30,144,255, true) // bg color
c.Println("message")
c.Printf("format %s", "message")

Create a style from an hexadecimal color string:

color.HEX(hex string, isBg ...bool) RGBColor

c := HEX("ccc") // can also: "cccccc" "#cccccc"
c.Println("message")
c.Printf("format %s", "message")

c = HEX("aabbcc", true) // as bg color
c.Println("message")
c.Printf("format %s", "message")

Use a RGB color style

Can be used to set the foreground and background colors at the same time.

color.NewRGBStyle(fg RGBColor, bg ...RGBColor) *RGBStyle

s := NewRGBStyle(RGB(20, 144, 234), RGB(234, 78, 23))
s.Println("message")
s.Printf("format %s", "message")

Create a style from an hexadecimal color string:

color.HEXStyle(fg string, bg ...string) *RGBStyle

s := HEXStyle("11aa23", "eee")
s.Println("message")
s.Printf("format %s", "message")
