Improvement: Multiple detection and Remove an user

[pachirel]

Multiple detection

Now we can increment multiple users at one line!

For example, this command will increment taro and hanako:
taro++, hanako++ ,

This will add 3 points to taro:
taro++ taro++ taro++

And, this is just a joke:
taro-- taro++

Remove an user

When you mistyped name, now you can remove it.

tarp++
hubot scorekeeper remove tarp

Add remove function is ok.

Multiple increment/decrement in one line is cool!
but IMO it lost readability.

Please change like this

robot.hear /(\w+)\+\+$/g, (msg) ->
  for str in msg.match
    user = userName(str)
    scorekeeper.increment user, (error, result) ->
      msg.send "incremented #{user} (#{result} pt)"

robot.hear /(\w+)\-\-$/g, (msg) ->
  for str in msg.match
    user = userName(str)
    scorekeeper.decrement user, (error, result) ->
      msg.send "decremented #{user} (#{result} pt)"

Indeed.

But I can't work your example code correctly in my local environment.
Using global match, msg.match returns entire matching string instead of captured string.
e.g. )When foo++ is coming, msg.match doesn't return foo, but foo++.
And, when foo++ bar-- is passed, foo++ is ignored.

Anyway, I'm working to refactor my PR code better 💃

thanks.
