/*
Welcome Message Plugin
======================
This plugin adds a new option to the repl opts called `welcome` that,
if set, will display the set string before starting the interpreter.
The welcome message can be set like so:

    nesh.start {welcome: 'Hello!'}, (err) ->
        console.log err if err
 */

(function() {
  require('colors');

  exports.name = 'welcome';

  exports.description = 'Displays a welcome message on startup';

  exports.setup = function(context) {
    var defaults;
    defaults = context.nesh.defaults;
    return defaults.welcome != null ? defaults.welcome : defaults.welcome = ("Node " + process.version + "\nType ") + ".help".cyan + " for more information";
  };

  exports.preStart = function(context) {
    var options, outStream;
    options = context.options;
    if (options.welcome) {
      outStream = options.outputStream || process.stdout;
      return outStream.write(options.welcome + "\n");
    }
  };

}).call(this);
