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
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

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)

 close 'n/2/{~@@/\*}/

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

The second, more obvious, one is the substitution table for compressing the output strings. This was generated manually, and may be susceptible to small improvements.

The first, less obvious unless you know GolfScript, 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.

For the benefit of non-GolfScript-speakers, and since Lowjacker specifically commented on it, the calculation of rep for an individual line is

.'un'/''*.0\{\-}/11%'n?imdop
p_l'=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.

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.

Java - 1519 chars

import java.util.*;public class A{static List m=new ArrayList();static String c="create",p="posts",w="wiki",e="edit",v="vote",t="tag",q="questions";

Scanner s=new Scanner(System.in);String i=s.nextLine();int r=0;int b;
while(!i.equals("")){b=r(i);if(b==1740)r-=15;if(b==1690)r-=10;if(b==1922)r-=5;if(b==1674||b==1906||b==1539)r-=2;if(b==1574)r-=1;if(b==1219||b==1801)r+=1;if(b==1312||b==2133||b==1901)r+=2;if(b==1695)r+=5;if(b==1463)r+=10;if(b==1513)r+=15;if(b==1764)r+=100;i=s.nextLine();}
System.out.println(r+" reputation");for(Object q:m)if(c(q,r))System.out.println((String)q);}
static boolean c(Object q,int r){StringTokenizer t=new StringTokenizer((String)q);if(Integer.parseInt(t.nextToken())<=r)return true;return false;}
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.

Answer 7

Scala 1089

object R extends App{val t=List(("j.*",1),(".*s",100),(".*r a.*",15),(".*r d.*",-2),(".*n d.*",-2),(".* una.*",-15),("u.*",-2),("ac.*",2),("und.*",1),("d.*",-1),(".*r up.*",10),(".*n up.*",5),(".*r unu.*",-10),(".*r .*",2),(".*n unu.*",-5),(".*n .*",2))
def a(s:String)=t.find(x=>s.matches(x._1)).map(x=>x._2).getOrElse(0)
var(r,s)=(0,"")
do{s=readLine
r+=a(""+s)}while(s!=null)
println(r+" reputation")
val (q,c)=(" questions","create ")
val d=List(1->(c+"posts"),5->"participate in meta",10->"remove new user restrictions",10->(c+"wiki posts"),15->"vote up",15->"flag posts",20->"talk in chat",50->"comment everywhere",75->"set bounties",100->"edit community wiki",100->(c+"chat rooms"),125->"vote down",150->(c+"tags"),200->("retag"+q),250->"view close votes",500->"cast close and reopen votes",750->"established user",1000->("edit"+q+" and answers"),1000->(c+"gallery chat rooms"),1250->(c+"tag synonyms"),1500->"approve tag wiki edits",2000->"access to moderator tools",3500->("protect"+q),4000->"trusted user")
d.filter(_._1<=r).toList.sortBy(_._1).map(v=>println((v._1)+" "+v._2))}

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:

reading data from file: 405

object R extends App{import io.Source._
import java.util._
def m(n:String)={fromFile(n).getLines.toList.map{l=>val s=new Scanner(l);(s.next(),s.nextLine())}}
val e=m("e").map(a=>(a._2.trim->a._1.replaceAll("\\+","").toInt)).toMap
val p=m("p").map(b=>(b._1.toInt,b._2))
var(r,t)=(0,"")
