Calculate a user's privileges on CodeGolf.SE

Question

The Challenge

Your goal is to write the shortest program possible that will take a list of events (such as upvote, downvote, etc) and return the user's reputation and the privileges that he has earned.

What sort of events?

Here is a chart of the events, listed in order of reputation earned:

-15 answer unaccepted
-10 answer unupvoted
-5  question unupvoted
-2  answer downvoted
-2  question downvoted
-2  unaccept answer
-1  downvote answer
+1  join website
+1  undownvote answer
+2  accept answer
+2  question undownvoted
+2  answer undownvoted
+5  question upvoted
+10 answer upvoted
+15 answer accepted
+100 association bonus

What sort of privileges?

Here is a list of privileges, in order of reputation required.

1 create posts
5 participate in meta
10 remove new user restrictions
10 create wiki posts
15 vote up
15 flag posts
20 talk in chat
50 comment everywhere
75 set bounties
100 edit community wiki
100 create chat rooms
125 vote down
150 create tags
200 retag questions
250 view close votes
500 cast close and reopen votes
750 established user
1000 edit questions and answers
1000 create gallery chat rooms
1250 create tag synonyms
1500 approve tag wiki edits
2000 access to moderator tools
3500 protect questions
4000 trusted user

Input

Input (on STDIN) will be a list of events, one per line, exactly how they appear in the first chart (except for the amount of reputation). A blank line represents the end of input. Here is an example (there should be a blank line at the end):

join website
association bonus
answer upvoted
answer upvoted
question upvoted
answer accepted
answer upvoted
accept answer
unaccept answer
question unupvoted
accept answer
question upvoted

Output

The first line of output (to STDOUT) should name the amount of rep accumulated. Each line after that should list one privilege earned, exactly as they appear and in the same order as the second chart. The expected output for the above input:

153 reputation
1 create posts
5 participate in meta
10 remove new user restrictions
10 create wiki posts

Rules, Restrictions, and Notes

This is code golf. Standard code golf rules apply.

(EDIT: Since I have had two entries that access files, I would like to point out that the length of the file needs to be added to code length as part of the standard rules for code golf)

GolfScript (569 568 475 473 chars)

This uses non-printable characters to compress the required strings, so in xxd format:

Pretty trivial in most respects, but there are two points of interest.

The first is the hash function for the input strings. I was astonished by how simple a hash function produces unique results for each of the 9 (once un is removed) different strings, and as a bonus it also produces a different result for the empty string, which saves stripping out the final blank line from the input.

The calculation of rep for an individual line is

.'un'/''*.-1base'n?imdop
p_l'12*=110-@@={~)}*

First, it removes un from the string, and makes a note of whether it was found. Then it applies a super-simple hash function, h(s) = ( sum over i: (-1)^i s[i] ) % 11. (You can see why I was surprised when I found it). The string

'n?imdop
p_l'

is a lookup table which maps the hash value to the change in rep (subtract 110 from the ASCII value), and then if it found un at the start it negates the change.

The second point of interest is the filter for the privileges. I tried a slightly simpler one:

{~^\<!},

which evaluates the line (undefined words do nothing) in order to get its score for comparison with the reputation (stored in ^). It almost works. The thing which breaks it is that and occurs in some of the strings, and is a pre-defined function. Solution: mangle the lines enough that and no longer occurs. (There is a case to be made that removing spaces would be better than removing the letter a, but it doesn't make any difference to the length).

Answer 2

Ruby 1.9.3, 514 467 459 (507 460 452 + 7 for flags)

Run with ruby -rzlib <program>.

#coding:binary

If the binary string literals didn't paste properly (which they probably didn't), here's a hex dump:

I think the basic idea is similar to many other people's approaches. I use a little home-made hash to deal with recognizing inputs. The hash conveniently gives zero for an empty string, making the input-reading line very compact. I'm sure that the hash could be greatly improved. Some good character savings could be gotten by allowing some strategic hash collisions for things that have the same reputation.

I also had some real perverse fun hiding a goto inside a macro (my first time ever using a goto, I'm proud to say).

The one place where I'm sure I have a lot of room for improvement is in the output section. I haven't even attempted to compress the actual printing logic, so I'm sure that I could save some characters there as well.

Or a bit more readable with added linebreaks and indentation:

#define P(x,m) if(s>=x)puts(#x" "#m);
s;char*e="&g 5 x$hg54  $  G5UC vg",l[99];

}

The above codes assumes a single newline at the end of the file. If there are two, then one needs to write s+=*l?e[…]:0 instead of s+=e[…], at an additional cost of 5 chars. Writing while(*gets(l)) would be shorter but won't work since I don't include headers, so the compiler assumes gets returns int not char*.

The hashing expression (l[11]%8^l[7])-97 was found by trying all expressions of the following forms, looking for the one with shortest resulting code length:

for i in range(13):
    for j in range(13):
        pat("a[i]^a[j]", i=i, j=j)
        pat("a[i]-a[j]", i=i, j=j)
        pat("a[i]|a[j]", i=i, j=j)
        pat("a[i]&a[j]", i=i, j=j)
        pat("a[i]*a[j]", i=i, j=j)
        pat("a[i]%a[j]", i=i, j=j)
        for k in range(13):
            pat("a[i]^a[j]^a[k]", i=i, j=j, k=k)
            pat("a[i]%a[j]^a[k]", i=i, j=j, k=k)
            pat("a[i]*a[j]^a[k]", i=i, j=j, k=k)
            pat("a[i]+a[j]^a[k]", i=i, j=j, k=k)
            pat("a[i]-a[j]^a[k]", i=i, j=j, k=k)
            pat("a[i]^a[j]|a[k]", i=i, j=j, k=k)
            pat("a[i]%a[j]|a[k]", i=i, j=j, k=k)
            pat("a[i]*a[j]|a[k]", i=i, j=j, k=k)
            pat("a[i]+a[j]|a[k]", i=i, j=j, k=k)
            pat("a[i]-a[j]|a[k]", i=i, j=j, k=k)
            pat("a[i]*k^a[j]", i=i, j=j, k=k)
            pat("a[i]%k^a[j]", i=i, j=j, k=k)
            pat("a[i]%k+a[j]", i=i, j=j, k=k)
            pat("a[i]%k-a[j]", i=i, j=j, k=k)
            pat("a[i]%k|a[j]", i=i, j=j, k=k)
            for l in range(13):
                pat("a[i]%k^a[j]%l", i=i, j=j, k=k, l=l)
        for k in range(100):
            pat("a[i]+k^a[j]", i=i, j=j, k=k)
            pat("a[i]-k^a[j]", i=i, j=j, k=k)

A suitable printable ASCII character representation was found using a similar brute force search.

Python 3 (743 715 chars)

In the same spirit as above. This one relies on a second newline at the end of the input, though.

s=0
while 1:
 l=input()
 if not l:break
 s+=b'>-/1/.04-1*//0//91%\x93/ -'[(ord(l[11])%8^ord(l[7]))-97]-47
print(s,"reputation")

static int r(String i){int r=0;for(int k=0;k<i.length();)r+=i.charAt(k++);return r;}}

To find reputation, it adds all the character in input string (example 'join website' adds to form 1219) and when b==1219, r=r+1.

Rewrote from scratch, nearly. If I have to calculate the data in, it is cheaper (while ugly) to include the data directly.

First approach, reading event prices and privilege tab from files:

The program consists of four parts:

1. the following decoder script (277 bytes)

   b=:,@#:@(a.i.fread)
   s=:(15+6*#.@(3{.12&}.))({.;$:^:(40<#)@}.)]
   r=:3 :'(15-~#.12{.y);;:^:_1[(#._6>\15}.y){u:@(96&+)&.>0 cut#._5>\b''w'''&.>@s@b
   f=:3 :'>>{.&.>e#~;((<y)=}.)&.>e=:r''e'''
   echo' reputation',~":R=:+/;f&.>LF cut 1!:1[3
   echo>((":@>@{.),' ',>@{:)&.>p#~R>>>{.&.>p=:r'p'
   

2. a binary words file, called w, also 277 bytes (download here).

   The file format is as follows: each word is encoded as a group of five-bit "bytes". Each group of five bits can have a value from 1 to 27 representing letters, or 0 being the separator. Every unique word in the description of the events and privileges is stored here.

3. a binary events file, called e, which is 54 bytes (download here).

   Each event consists of a 12-byte reputation and one or more 6-byte words. For example, accept answer is encoded as follows:

    rep+15       Nwords  word1    word2
    000000010001 010     000110   011101
    17           2       6        29     <- these are indices in "w"
                         "accept" "answer"
   

4. a binary privileges file, called p, which is 96 bytes (download here).

   The file format is the same as e, e.g. access to moderator tools is encoded as follows:

   rep+15       Nwords word1    word2  word3       word4
   011111011111 100    011010   011011 100000      010000
   2015         4      26       27     32          16
                       "access" "to"   "moderator" "tools"

It won't win any prizes but gosh darn it I just can't figure out how to make this any smaller, so I'll just post it:

<?php
while($l=fgets(STDIN))foreach(@[j=>1,bo=>100,pt=>2,pte=>13,'r un?u?p'=>5,up=>5,wn=>-2,'e '=>1]as$k=>$v)@$r+=$v*ereg($k,$l)*(ereg(un,$l)?-1:1);$p=@preg_replace;foreach(split('
',$p('/[A-Z]/e','" ".$p("/.*?$0|[A-Z].*/","",@AaCcreateEeditGtagHchatIinLcloseMcommPpostsQquestionsRroomsTtUuserVvoteWwikiZre)',$r."Zputation

";

Since the part that calcs the rep is very hard to read, here it is with extra formatting. It abuses undefined constants and uses @ to shut them up:

while($l=fgets(STDIN))
foreach(@[
        j=>1, // join website
        bo=>100, // association bonus
        pt=>2, // (un)?accept answer|answer (un)?accepted
        pte=>13, // answer (un)?accepted
        'r un?u?p'=>5, // answer (un)?upvoted
        up=>5, // (answer|question) (un)?upvoted
        wn=>-2, // (answer|question) (un)?downvoted|(un)?downvote answer
        'e '=>1 // (un)?downvote answer
        ]as$k=>$v)
    @$r+=$v*ereg($k,$l)*(ereg(un,$l)?-1:1);

Python 3.x (801 chars)

Best I can do so far, just need to work out a better encoding than base64 (hint hint: can somebody assist?).
