type Error = Either String Source #

Alias for types with an error message

Namecoin config parser

comment :: Parser () Source #

Parse a comment (line beggining with a "#")

setting :: Parser (Text, Text) Source #

Parse an option of form

key=value

line :: Parser (Text, Text) Source #

Parse a line (either a comment or an option)

config :: Parser [(Text, Text)] Source #

Parse the namecoin config format

uri :: Text -> Error String Source #

Takes the content of a namecoin config file and gives the URI to connect to the JSON-RPC server
