parseEmail - simple superscript plugin to parse and return an email address from an input string

parseEmail.js

var debug = require("debug")("parseEmail Plugin");
var emailRegex = require("email-regex");

exports.parseEmail = function(star, cb) {
  // function to parse either a passed string or the entire message
  var input;

  if (typeof(star) === 'function') {
    cb = star;
    star = null;

    // get 'original' message so that we don't lose .tld due to ss message processing
    debug("No input provided. Processing original message: %s", this.message.original);
    input = this.message.original;
  } else {
    debug("Using input provided: %s", star);
    input = star;
  }

  var result = input.match(emailRegex());

  if (!result) {
    debug("No email found.");
    cb(null, "");
  } else {
    debug("Found email: %s. Adding to message props", result);
    this.message.props["email"] = result;
    cb(null, "");
  }

};

That looks good. I'm courious how you would use this in the actuall reply it seems a little restrictive.

I was using that as a generic helper that I can call whenever I need to grab an email. What I'm now trying to do is create a saveEmail plugin that calls this when I actually want to save an email. Definitely open to suggestions on better ways!

updated to handle either passed input (for if/when we can pass a wildcard) or the original message. Now adds the email to the message props instead of returning it.
