urlencoded- Generate or process x-www-urlencoded data

Safe HaskellNone




Implements a data type for constructing and destructing x-www-urlencoded strings. See http://www.w3.org/TR/html401/interact/forms.html#h-


Representation of a URL-encoded string

filter :: ((String, String) -> Bool) -> URLEncoded -> URLEncoded Source #

Create a URLEncoded object that represents all pairs from the input that match the supplied predicate

class URLShow a where Source #

Serialize a value into a String for encoding as part of an x-www-urlencoded value

Minimal complete definition



urlShow :: a -> String Source #

class URLEncode a where Source #

Encode a value as x-www-urlencoded

Minimal complete definition



urlEncode :: a -> URLEncoded Source #


empty :: URLEncoded Source #

URLEncoded data with no pairs

importString :: MonadError e m => String -> m URLEncoded Source #

Parse this string as x-www-urlencoded

importList :: [(String, String)] -> URLEncoded Source #

Import this list of pairs as URLEncoded data

(%=) :: (URLShow a, URLShow b) => a -> b -> URLEncoded infixl 8 Source #

Create singleton URLEncoded data containing the supplied key and value

(%=?) infixl 8 Source #


:: (URLShow a, URLShow b) 
=> a


-> Maybe b


-> URLEncoded 

If the second value is Nothing, return empty URLEncoded data. Otherwise return singleton URLEncoded data that contains the given key and value.

(%&) :: (URLEncode q1, URLEncode q2) => q1 -> q2 -> URLEncoded infixr 7 Source #

class AddURLEncoded a where Source #

Minimal complete definition



(%?) :: URLEncode args => a -> args -> a infixr 6 Source #


AddURLEncoded URI Source # 


(%?) :: URLEncode args => URI -> args -> URI Source #

AddURLEncoded URLEncoded Source # 


(%?) :: URLEncode args => URLEncoded -> args -> URLEncoded Source #

AddURLEncoded [Char] Source # 


(%?) :: URLEncode args => [Char] -> args -> [Char] Source #


null :: URLEncoded -> Bool Source #

Is this URLEncoded data empty?

keys :: URLEncoded -> [String] Source #

All of the keys from the URLEncoded value, in order, preserving duplicates

lookupAll :: URLShow a => a -> URLEncoded -> [String] Source #

Return all values whose keys match the supplied key, in the order they appear in the query. Will return an empty list if no keys match.

lookup1 :: (URLShow a, MonadError e m) => a -> URLEncoded -> m String Source #

Return the first value for the given key, or throw an error if the key is not present in the URLEncoded data.

(%!) :: URLShow a => URLEncoded -> a -> Maybe String infixr 1 Source #

Look up a key in a URLEncoded value and return the first matching value, or Nothing if there is no value that matches


addToURI :: URLEncoded -> URI -> URI Source #

Add this URL-encoded data to the query part of a URI, after any existing query arguments.

export :: URLEncoded -> String Source #

Convert this URLEncoded object into an x-www-urlencoded String (The resulting string is 7-bit clean ASCII, containing only unreserved URI characters and %-encoded values)
