Documentation
class Applicative m => ConfigParser m whereSource
The ConfigParser type class abstracts over ConfigParserM and
ConfigParserA. This is intended to be a closed typeclass, without
any additional instances.
Methods
configParser_ :: RMW Config ConfigErrors a -> m aSource
unConfigParser_ :: m a -> RMW Config ConfigErrors aSource
newtype ConfigParserM a Source
A computation produces a value of type ConfigParserM a
from a given Maybe aConfig, in addition to a list of diagnostic messages
which may be interpreted as warnings or errors as deemed appropriate.
If the value returned by a computation is Nothing, then no subsequent
actions (e.g. via <*> or >>=) will be performed.

newtype ConfigParserA a Source
A computation produces a value of type ConfigParserM a
from a given Maybe aConfig, in addition to a list of diagnostic messages.
After executing a subcomputation that returns a Nothing value,
computations of type ConfigParserA will continue to run in order to
produce more error messages. For this reason, ConfigParserA does
not have a proper Monad instance. (But see unsafeBind)

newtype ConfigTransform Source
Conceptually, a ConfigTransform is a function Config -> Config.
It's a restricted subset of such functions as to preserve the possibility
of reliable dependency tracking in later versions of configurator-ng.
