I basically try to split Stringinto [[String]]and then concatform the results, but keeping the delimiters in the resulting list (even repeating in a line).
Something like work below, but the separator gets a crunch in one space instead of keeping all three spaces
unwords . map (\x -> "|" ++ x ++"|") . words $ "foo bar"
-- "|foo| |bar|"
Ideally, I could get something like:
"|foo|| ||bar|" -- or
"|foo| |bar|"
I just can’t understand how to save the separator, all the separation functions that I saw dropped the separators from the resulting lists, I can write them myself, but it looks like it will be in the standard library and at this moment I want to learn more than the basics that include getting to know more conversational ways of doing things.
I think I'm looking for some kind of function, for example:
splitWithDelim :: Char -> String -> [String]
splitWithDelim "foo bar" -- ["foo", " ", " ", " ", "bar"]
