Re: [Haskell-beginners] Count Words In File

I had thought about doing something like that, except about 80% of the time the words in the file won't have a delimitor such as in "theblueskythegreenearth" but I still need to be able to count "the" or the ordered sequence of [ t, h, e ] within such a character string (or [ b, l, u, e ] or whatever) Again, thank you for your time & thanks in advance.

Hello,

I apologize in advance if this is crossposting. My IRC client did not appear to be working properly.

I am new to Haskell and I need to find a way to count specific words in a file. File could contain spaces between words, no spacing, uppercase, lowercase, etc so I've standardized it to once the file is taken in, convert to lowercase and remove the spacing. I've also read the postings about using ByteString instead of [Char] so I am trying to use that. But, as it still seems to either view all elements as fused or each letter as individual, I'm not entirely sure how to tackle this. The input after transforming would be something like "theblueskyisveryblue" for uniformity and would need to count "the" and "blue". Feels like I should be able to do a map and foldr(?) but I'm not sure how to get Haskell to recognize 'the' for example and not count all the t's, h's, e's etc in the file, nor am I entirely sure how to properly compose a map-fold for character arrays like this.

Thanks in advance and thank you for your time.
