Package socket implements an WebSocket-based playground backend. Clients connect to a websocket handler and send run/kill commands, and the server sends the output and exit status of the running processes. Multiple clients running multiple processes may be served concurrently. The wire format is JSON and is described by the Message type.

    This will not run on App Engine as WebSockets are not supported there.

    var Environ func() []string = os.Environ

      Environ provides an environment when a binary, such as the go tool, is invoked.

      var RunScripts = true

        RunScripts specifies whether the socket handler should execute shell scripts (snippets that start with a shebang).


        func NewHandler

        func NewHandler(origin *url.URL) websocket.Server

          NewHandler returns a websocket server which checks the origin of requests.


          type Message

          type Message struct {
          	Id      string // client-provided unique id for the process
          	Kind    string // in: "run", "kill" out: "stdout", "stderr", "end"
          	Body    string
          	Options *Options `json:",omitempty"`

            Message is the wire format for the websocket connection to the browser. It is used for both sending output messages and receiving commands, as distinguished by the Kind field.

            type Options

            type Options struct {
            	Race bool // use -race flag when building code (for "run" only)

              Options specify additional message options.
