# go-colorable
[![Build Status](https://github.com/mattn/go-colorable/workflows/test/badge.svg)](https://github.com/mattn/go-colorable/actions?query=workflow%3Atest)
[![Codecov](https://codecov.io/gh/mattn/go-colorable/branch/master/graph/badge.svg)](https://codecov.io/gh/mattn/go-colorable)
[![GoDoc](https://godoc.org/github.com/mattn/go-colorable?status.svg)](http://godoc.org/github.com/mattn/go-colorable)
[![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

### context.Context integration
Go contexts are commonly passed throughout Go code, and this can help you pass
your Logger into places it might otherwise be hard to inject. The `Logger`
instance may be attached to Go context (`context.Context`) using
`Logger.WithContext(ctx)` and extracted from it using `zerolog.Ctx(ctx)`.
For example:
```go
func f() {
logger := zerolog.New(os.Stdout)
ctx := context.Background()
// Attach the Logger to the context.Context
ctx = logger.WithContext(ctx)
someFunc(ctx)
}
func someFunc(ctx context.Context) {
// Get Logger from the go Context. if it's nil, then
// `zerolog.DefaultContextLogger` is returned, if
// `DefaultContextLogger` is nil, then a disabled logger is returned.
logger := zerolog.Ctx(ctx)
logger.Info().Msg("Hello")
}
```
A second form of `context.Context` integration allows you to pass the current
context.Context into the logged event, and retrieve it from hooks. This can be
useful to log trace and span IDs or other information stored in the go context,
and facilitates the unification of logging and tracing in some systems:
```go
type TracingHook struct{}
func (h TracingHook) Run(e *zerolog.Event, level zerolog.Level, msg string) {
ctx := e.GetCtx()
spanId := getSpanIdFromContext(ctx) // as per your tracing framework
e.Str("span-id", spanId)
}
func f() {
// Setup the logger
logger := zerolog.New(os.Stdout)
logger = logger.Hook(TracingHook{})
ctx := context.Background()
// Use the Ctx function to make the context available to the hook
logger.Info().Ctx(ctx).Msg("Hello")
}
```

* `zerolog.DurationFieldInteger`: If set to `true`, `Dur` fields are formatted as integers instead of floats (default: `false`).
* `zerolog.ErrorHandler`: Called whenever zerolog fails to write an event on its output. If not set, an error is printed on the stderr. This handler must be thread safe and non-blocking.
* `zerolog.FloatingPointPrecision`: If set to a value other than -1, controls the number
of digits when formatting float numbers in JSON. See

In this case, many consumers will take the last value, but this is not guaranteed; check yours if in doubt.
### Concurrency safety
Be careful when calling UpdateContext. It is not concurrency safe. Use the With method to create a child logger:
```go
func handler(w http.ResponseWriter, r *http.Request) {
// Create a child logger for concurrency safety
logger := log.Logger.With().Logger()
// Add context fields, for example User-Agent from HTTP headers
logger.UpdateContext(func(c zerolog.Context) zerolog.Context {

})
}
