remote-js's Issues

Sample code error

Hi @eudoxia0

The example code on the documentation has some errors that prevent an easy tryout of the lib, at least in windows.

1. When calling make-context by default, server will be 0.0.0.0; this wouldn't work on windows systems.

It must be something like:

(remote-js:make-context 
                    :address "127.0.0.1"
                    :port 40000)

1.1 Context IP address needs to be a string otherwise the produced HTML won't work. I mention this, because the usual convention on other libs is to specify IP address as a vector of ints.

1.2 This makes the remote-js test fail, at least on Windows, since it sets address to 0.0.0.0

1.2.1 And it will fail anyways, since trivial-open-browser invokes "explorer " which opens a file explorer and no url.

2. The context server needs to be started to be used. This isn't mentioned on the documentation.

Server doesn't execute the callback

Environment

Windows 10 64-bit
Chrome 71.0 64-bit

steps:

1. Make context to 127.0.0.1 port 40000, with callback exactly as shown on the example (should print a message after receiving callback)
2. Create HTML with remote-js:html
3. Open HTML in browser
4. Try remote-js:eval to send js code to the browser. Result: Success, i can make the browser show an alert.
5. Try remote-js:eval to make the client execute RemoteJS.send('hi!'), exactly as in the example.

Expected result:
"Received: hi" on the REPL console

Actual Result:
No message. Callback appears to not be executed.

Status of the context class:

#<REMOTE-JS:CONTEXT {10039C4B43}>
