# 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!
|
||||
|
||||
|
||||
|
||||
|
||||
## So Good!
|
||||
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
```go
|
||||
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
|
||||
```
