Santa's Decision

Question

Santa's Decision:

In this challenge, you will help Santa Claus decide whether somebody on their list has been naughty or nice, and subsequently get coal or toys.

But unfortunately, Santa is unorganised, in some of his entries, the naughty, nice and name fields are in the wrong order.

Input

Input will come in the following, interchangeable format:

• the person's name (cannot contain a colon, only a-zA-Z0-9)
• the word naughty followed directly by a colon and an non-negative integer representing the amount of times Santa caught you being naughty
• the word nice followed directly by a colon and an non-negative integer representing the amount of times Santa caught you being nice

All separated with a single whitespace (ASCII 32) between each of them.

Additionally, the name will have no whitespace between the parts of the name Santa Claus -> SantaClaus.

Bonus:

• (25%): He is Santa Claus, so he needs to check the list twice, and make sure there are no duplicates. (In which case, it just gets the first scores that user has)

Example:

Quill naughty:4 nice:0
naughty:0 Doorknob nice:3
naughty:2 Quill nice:6
nice:3 balpha naughty:3
pops nice:4 naughty:2

Output:

The output should consist of:

The name of the person followed by:

• If there's more points in naughty, then coal:
• If there's more points in nice, then toys.

• But if naughty and nice are equal, then needs more data

  Example output:

• With organisation bonus and duplicate removal bonus:

Quill coal
Doorknob toys
balpha needs more data
pops toys

• Without bonus:

Quill coal
Doorknob toys
Quill toys
balpha needs more data
pops toys

Julia, 176 169 bytes

s->for l=split(s,"\n") M(r)=parse(matchall(r,l)[1]);g=M(r"e:\K\d+");b=M(r"y:\K\d+");println(replace(l,r" *\w+:\d+ *","")," ",g>b?"toys":b>g?"coal":"needs more data")end

This is an anonymous function that accepts a string and prints the result to STDOUT. To call it, give it a name, e.g. f=s->....

Ungolfed:

function santa(s::AbstractString)
    # Split the input on newlines and process each line separately
    for l in split(s, "\n")
        # Define a function to get the number from the result of a
        # regular expression match
        M(r) = parse(matchall(r, l)[1])

        # Goodness
        g = M(r"e:\K\d+")

        # Badness
        b = M(r"y:\K\d+")

        # Get the name by replacing the naughty and nice specifications
        # with empty strings and print the line to STDOUT
        println(replace(l, r" *\w+:\d+ *", ""), " ",
                g > b ? "toys" : b > g ? "coal" : "needs more data")
    end

Perl, 138 113 105 103 102 96 - 25% = 72

includes +1 for -p

s/ *\w*(.):(\d+) */$$1=$2,()/eg;$$_++?$_='':s/\n/$".('needs more data',toys,coal)[$e<=>$y].$&/e

Less golfed:

s/ *\w*(.):(\d+) */$$1=$2,()/eg;    # strip naughty/nice, set $a to naughty, $i to nice
                                    # $_ is now the input name followed by \n
$$_++ ? $_='' :                     # only output once per name
s/\n/                               # replace newlines with:
  $".                               # a space,
  ('needs more data',toys,coal)     # one of these strings,
  [$e<=>$y]                         # indexed by -1, 0 or 1
  .$&                               # and the matched newline.

• update 113
  • save 25 bytes by using 1 letter from nice or naughty as variable name;
  • loose 5 bytes by fixing bug when name is last
• update 105 save 8 bytes by using <=> to index a list of output strings.
• update 103 save 2 bytes by using regex to append output string
• update 102 save 1 byte by using last letter of nice or naughty instead of 2nd.
• update 96 save 6 bytes by changing $$_ ? ... : ($$_++, ...) into $$_++ ? ... : ...
  (why didn't I see that before).

Ungolfed

Usage:

# Assign the anonymous function to a variable
