U happen to find a way for your problem? I tried a lot for more than a week
now, but cant do it.
I tried many tutorials but wasnt of any good.
as per the above case study, I need to do is:
1) Allow words to be hyphenated and treat a hyphenated
word as a single word. However, for those words which are split over two
lines, treat a split word as a single word without the hyphen.
for this i tried:
fixupHyphens :: [ (Int, Word) ] -> [ (Int, Word ) ]
fixupHyphens ( (line1, word1):(line2:word2):xs )
| if (word1, line2) /= line1 = ( line1,word2 ) : fixupHyphens xs
| otherwise = (line1, word1):(line2:word2): fixupHyphens xs
fixupHyphens xs = xs
and for including hiphens i added this to the code:
splitWords :: Line -> [Word] -- a)
splitWords [] = []
splitWords line
= takeWhile isLetter line : -- first word in line
(splitWords . -- split other words
dropWhile (not.isLetter) . -- delete separators
dropWhile isLetter) line -- other words
where
isLetter ch
= (('a'<=ch) && (ch<='z'))
|| (('A'<=ch) && (ch<='Z'))
|| ('-' = ch)
2)Treat a capitalised word (one or more capitals) as being different from the
word in all lower case (but they should still be sorted alphabetically)unless
it is at the start of a sentence with only the initial letter capitalised.
