# ansi

Package ansi is a small, fast library to create ANSI colored strings and codes.

## Install

Get it

```sh

go get -u github.com/mgutz/ansi

```

## Example

```go

import "github.com/mgutz/ansi"

// colorize a string, SLOW

msg := ansi.Color("foo", "red+b:white")

// create a FAST closure function to avoid computation of ANSI code

phosphorize := ansi.ColorFunc("green+h:black")

msg = phosphorize("Bring back the 80s!")

msg2 := phospohorize("Look, I'm a CRT!")

// cache escape codes and build strings manually

lime := ansi.ColorCode("green+h:black")

reset := ansi.ColorCode("reset")

fmt.Println(lime, "Bring back the 80s!", reset)

```

Other examples

```go

Color(s, "red")            // red

Color(s, "red+d")          // red dim

Color(s, "red+b")          // red bold

Color(s, "red+B")          // red blinking

Color(s, "red+u")          // red underline

Color(s, "red+bh")         // red bold bright

Color(s, "red:white")      // red on white

Color(s, "red+b:white+h")  // red bold on white bright

Color(s, "red+B:white+h")  // red blink on white bright

Color(s, "off")            // turn off ansi codes

```

To view color combinations, from project directory in terminal.
