Documentation
stringTrim :: String -> String
remove leading and trailing whitespace with standard Haskell predicate isSpace
stringToLower :: String -> String
convert string to lowercase with standard Haskell toLower function
stringToUpper :: String -> String
convert string to uppercase with standard Haskell toUpper function
stringAll :: Eq a => [a] -> [a] -> [Int]
find all positions where a string occurs within another string
stringFirst :: Eq a => [a] -> [a] -> Maybe Int
find the position of the first occurence of a string
stringLast :: Eq a => [a] -> [a] -> Maybe Int
find the position of the last occurence of a string
normalizeNumber :: String -> String
Removes leading / trailing whitespaces and leading zeros
normalizeWhitespace :: String -> String
Reduce whitespace sequences to a single whitespace
normalizeBlanks :: String -> String
replace all whitespace chars by blanks
escapeURI :: String -> String
Escape all disallowed characters in URI references (see http://www.w3.org/TR/xlink/#link-locators)
textEscapeXml :: String -> String

escape XML chars < and ampercent by transforming them into character references, used for escaping text nodes

see also : attrEscapeXml

stringEscapeXml :: String -> String

escape XML chars <, >, ", and ampercent by transforming them into character references

see also : attrEscapeXml

attrEscapeXml :: String -> String

escape XML chars in attribute values, same as stringEscapeXml, but none blank whitespace is also escaped

see also : stringEscapeXml

stringToInt :: Int -> String -> Int
stringToHexString :: String -> String

convert a string into a hexadecimal string applying charToHexString

see also : charToHexString

charToHexString :: Char -> String

convert a char (byte) into a 2-digit hexadecimal string

see also : stringToHexString, intToHexString

intToHexString :: Int -> String

convert a none negative Int into a hexadecimal string

see also : charToHexString

hexStringToInt :: String -> Int
convert a string of hexadecimal digits into an Int
decimalStringToInt :: String -> Int
convert a string of digits into an Int
doubles :: Eq a => [a] -> [a]
take all elements of a list which occur more than once. The result does not contain doubles. (doubles . doubles == doubles)
singles :: Eq a => [a] -> [a]
drop all elements from a list which occur more than once.
noDoubles :: Eq a => [a] -> [a]
remove duplicates from list
swap :: (a, b) -> (b, a)
partitionEither :: [Either a b] -> ([a], [b])
toMaybe :: Bool -> a -> Maybe a
uncurry3 :: (a -> b -> c -> d) -> (a, b, c) -> d
mothers little helpers for to much curry
uncurry4 :: (a -> b -> c -> d -> e) -> (a, b, c, d) -> e
