- data Token = Token ByteString (Maybe ByteString)
- type Line = [Token]
- key :: ByteString -> [Token] -> Bool
- value :: ByteString -> [Token] -> Maybe ByteString
- valueAs :: Parser a -> ByteString -> [Token] -> Maybe a
Documentation
A token is a key and can maybe have an associated value
Constructors
| Token ByteString (Maybe ByteString) |
A line is just a sequence of tokens -- the Parser ends the chain
when a newline is received.
Arguments
| :: ByteString | The key to look for |
| -> [Token] | Tokens to consider |
| -> Bool | Result |
Returns true if the key was found
Arguments
| :: ByteString | Key to look for |
| -> [Token] | Tokens to consider |
| -> Maybe ByteString | The value if the key was found |
Looks up a key and returns the value if found
