# resync

`sync.Once` with `Reset()`

  * See [sync.Once](http://golang.org/pkg/sync/#Once)

Rather than adding this project as a dependency, consider [dropping](https://github.com/matryer/drop) this file into your project.

## Example

The following example examines how `resync.Once` could be used in a HTTP server situation.

```go

// use it just like sync.Once

var once resync.Once

// handle a web request

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

	once.Do(func(){

		// load templates or something

	})

	// TODO: respond

}

// handle some request that indicates things have changed

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

	once.Reset() // call Reset to cause initialisation to happen again above

}

```
