Haskell load external txt file into list -

-

hello following code wordfeud program. allows search through list of words matching prefix, suffix, , letters. question is, instead of using list @ bottom, want use external text file containing words , load list. how go doing this?

count :: string -> string -> int count _[] = 0 count [] _ = 0 count (x:xs) square     |x `elem` square = 1 + count xs (delete x square)     |otherwise = count xs square  check :: string -> string -> string -> string -> bool check prefix suffix word square     | (length strippedword) == (count strippedword square) = true     | otherwise = false             strippedword = drop (length prefix) (take ((length word ) - (length suffix)) word)   wordfeud :: string -> string -> string -> [string] wordfeud b c = test1         test =["horse","chair","chairman","bag","house","mouse","dirt","sport"]      test1 = [x| x <- test, `isprefixof` x, b `issuffixof` x, check b x c]

very simple, of lines function (or words, when words seperated other form of whitespace line breaks):

-- loads words text file list. getwords :: filepath -> io [string] getwords path = contents <- readfile path                    return (lines contents)

furthermore, you'll have read on io in haskell (i recommend googling 'io haskell tutorial'), if haven't done already. you'll need introduce interactivity program.

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
