Documentation
stringTrim :: String -> StringSource
remove leading and trailing whitespace with standard Haskell predicate isSpace
stringToLower :: String -> StringSource
convert string to lowercase with standard Haskell toLower function
stringToUpper :: String -> StringSource
convert string to uppercase with standard Haskell toUpper function
normalizeNumber :: String -> StringSource
Removes leading / trailing whitespaces and leading zeros
normalizeWhitespace :: String -> StringSource
Reduce whitespace sequences to a single whitespace
normalizeBlanks :: String -> StringSource
replace all whitespace chars by blanks
escapeURI :: String -> StringSource
Escape all disallowed characters in URI references (see http://www.w3.org/TR/xlink/#link-locators)
textEscapeXml :: String -> StringSource

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

see also : attrEscapeXml

stringEscapeXml :: String -> StringSource

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

see also : attrEscapeXml

attrEscapeXml :: String -> StringSource

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

see also : stringEscapeXml

stringToInt :: Int -> String -> IntSource
stringToHexString :: String -> StringSource

convert a string into a hexadecimal string applying charToHexString

see also : charToHexString

charToHexString :: Char -> StringSource

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

see also : stringToHexString, intToHexString

intToHexString :: Int -> StringSource

convert a none negative Int into a hexadecimal string

see also : charToHexString

hexStringToInt :: String -> IntSource
convert a string of hexadecimal digits into an Int
decimalStringToInt :: String -> IntSource
convert a string of digits into an Int
doubles :: Eq a => [a] -> [a]Source
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]Source
drop all elements from a list which occur more than once.
noDoubles :: Eq a => [a] -> [a]Source
remove duplicates from list
swap :: (a, b) -> (b, a)Source
partitionEither :: [Either a b] -> ([a], [b])Source
toMaybe :: Bool -> a -> Maybe aSource
uncurry3 :: (a -> b -> c -> d) -> (a, b, c) -> dSource
mothers little helpers for to much curry
uncurry4 :: (a -> b -> c -> d -> e) -> (a, b, c, d) -> eSource
