# contextplus

Package contextplus provide more easy to use functions for contexts.

# Use

```

go get -u github.com/contextplus/contextplus

```

# Example

This is how an http.Handler should run a goroutine that need values from the context. Pretend to use the middleware that timeout after one second.

```golang

func myMiddleware(next http.Handler) http.Handler {

	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {

		ctx := r.Context()

		ctx, cancel := context.WithTimeout(time.Second)

		defer cancel()

		r = r.WithContext(ctx)

		next.ServeHTTP(w, r)

	})

}

```

```golang

func handle(w http.ResponseWriter, r *http.Request) {

	asyncCtx := contextplus.WithOnlyValue(r.Context())

	go func() {

		// will not cancel if timeout

		// will not cancel if call 'cancel'

		asyncTask(asyncCtx)

	}()

}

```

```golang

func handle(w http.ResponseWriter, r *http.Request) {

	asyncCtx := contextplus.WithoutCancel(r.Context())

	go func() {

		// will cancel if timeout

		// will not cancel if call 'cancel'

		asyncTask(asyncCtx)

	}()

}

```
