# go-colorable
[![Godoc Reference](https://godoc.org/github.com/mattn/go-colorable?status.svg)](http://godoc.org/github.com/mattn/go-colorable)
[![Build Status](https://travis-ci.org/mattn/go-colorable.svg?branch=master)](https://travis-ci.org/mattn/go-colorable)
[![Coverage Status](https://coveralls.io/repos/github/mattn/go-colorable/badge.svg?branch=master)](https://coveralls.io/github/mattn/go-colorable?branch=master)
[![Go Report Card](https://goreportcard.com/badge/mattn/go-colorable)](https://goreportcard.com/report/mattn/go-colorable)
Colorable writer for windows.
For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
This package is possible to handle escape sequence for ansi color on windows.
## Too Bad!
![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/bad.png)
## So Good!
![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/good.png)
## Usage
```go
logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
logrus.SetOutput(colorable.NewColorableStdout())
logrus.Info("succeeded")
logrus.Warn("not correct")
logrus.Error("something error")
logrus.Fatal("panic")
```
You can compile above code on non-windows OSs.
## Installation
```
$ go get github.com/mattn/go-colorable

# 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+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.
```sh
go test
```
## Style format
```go
"foregroundColor+attributes:backgroundColor+attributes"
```
Colors
* black
* red
* green
* yellow
* blue
* magenta
* cyan
* white
* 0...255 (256 colors)
Foreground Attributes
* B = Blink
* b = bold
* h = high intensity (bright)
* i = inverse
* s = strikethrough
* u = underline
Background Attributes
* h = high intensity (bright)
## Constants
* ansi.Reset
* ansi.DefaultBG
* ansi.DefaultFG
* ansi.Black
* ansi.Red
* ansi.Green
* ansi.Yellow
* ansi.Blue
* ansi.Magenta
* ansi.Cyan
* ansi.White
* ansi.LightBlack
* ansi.LightRed
* ansi.LightGreen
* ansi.LightYellow
* ansi.LightBlue
* ansi.LightMagenta
* ansi.LightCyan
* ansi.LightWhite
