Color

A lightweight package that provides utilities for colorizing terminal output using ANSI escape codes.

Installation

To install color, you can use go get:

go get github.com/gabefiori/color

Import the gabefiori/color package:

package your

import (
    "fmt"
	"github.com/gabefiori/color"
)

func main() {
    b := color.Blue("blue text!")
    fmt.Println(b)
}

Examples

b1 := color.Blue("returns string with blue text")

// Background colors are also available.
b2 := color.BlueBg("returns a string with blue background")

fmt.Println(b1, b2)

// Colorization can be disabled.
// By default, it will be disabled if the "NO_COLOR" environment variable is set.
color.NoColor = true
fmt.Println(color.Blue("no color..."))

color.NoColor = false

// Any type is accepted, but some types, like string, []byte, or any kind of number (e.g., int, int8, uint32...)
// are optimized.
_ = color.Red(100)
_ = color.Red(uint(100))
_ = color.Red([]byte("hey"))

// Only 16 styles are available, but you can create your own.
brightRed := "\x1b[91m"
redOnWhite := "\x1b[31;47m"
rgb := "\x1b[38;2;50;200;100m"

_ = color.Wrap(brightRed, "hello")
_ = color.Wrap(redOnWhite, "hello")
_ = color.Wrap(rgb, "hello")
