stringTrim :: String -> String | Source
remove leading and trailing whitespace with standard Haskell predicate isSpace
stringToLower :: String -> String | Source
convert string to lowercase with standard Haskell toLower function
stringToUpper :: String -> String | Source
convert string to uppercase with standard Haskell toUpper function
stringAll :: Eq a => [a] -> [a] -> [Int] | Source
find all positions where a string occurs within another string
stringFirst :: Eq a => [a] -> [a] -> Maybe Int | Source
find the position of the first occurence of a string
stringLast :: Eq a => [a] -> [a] -> Maybe Int | Source
find the position of the last occurence of a string
normalizeNumber :: String -> String | Source
Removes leading / trailing whitespaces and leading zeros
normalizeWhitespace :: String -> String | Source
Reduce whitespace sequences to a single whitespace
normalizeBlanks :: String -> String | Source
replace all whitespace chars by blanks
escapeURI :: String -> String | Source
Escape all disallowed characters in URI references (see http://www.w3.org/TR/xlink/#link-locators)
textEscapeXml :: String -> String | Source
escape XML chars &lt; and ampercent by transforming them into character references, used for escaping text nodes see also : `attrEscapeXml`
stringEscapeXml :: String -> String | Source
escape XML chars &lt;, &gt;, &quot;, and ampercent by transforming them into character references see also : `attrEscapeXml`
attrEscapeXml :: String -> String | Source
escape XML chars in attribute values, same as stringEscapeXml, but none blank whitespace is also escaped see also : `stringEscapeXml`
stringToInt :: Int -> String -> Int | Source
stringToHexString :: String -> String | Source
convert a string into a hexadecimal string applying charToHexString see also : `charToHexString`
charToHexString :: Char -> String | Source
convert a char (byte) into a 2-digit hexadecimal string see also : `stringToHexString`, `intToHexString`
intToHexString :: Int -> String | Source
convert a none negative Int into a hexadecimal string see also : `charToHexString`
hexStringToInt :: String -> Int | Source
convert a string of hexadecimal digits into an Int
decimalStringToInt :: String -> Int | Source
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 a | Source
uncurry3 :: (a -> b -> c -> d) -> (a, b, c) -> d | Source
mothers little helpers for to much curry
uncurry4 :: (a -> b -> c -> d -> e) -> (a, b, c, d) -> e | Source
