Documentation on input, output and error handlers too sparse

[Kappie]

I'm trying to make a ruby REPL on my site, but the documentation on the input, output and error args in the Ruby.initialize function needs more examples.

How, for example, do I set up the input callback with jq-console?

input = ->
  jqconsole.Input( (input) ->
    jqconsole.Write(input) )
  console.log("input callback fired")
  return null

"input callback fired" is logged before I can type input in the console. How do I pass user input from the console to the input callback when jqconsole.Input seems to wait for other functions to finish?

Emscripten stream input is synchronous, while JQConsole's input is asynchronous. There's no simple way to connect them. JSRepl uses a hack: either a server or a client-side database as a sync point:
