input' :: Monad m => (String -> String -> xml) -> Maybe String -> Form xml m StringSource
Helper function for genereting input components based forms.
check :: Monad m => Form xml m a -> (a -> Failing b) -> Form xml m bSource
Add additional validation to an already validated component
Arguments
| :: Show a | |
| => (a -> Bool) | The predicate |
| -> String | The error message, in case the predicate fails |
| -> a | The value |
| -> Failing a |
Apply a predicate to a value and return Success or Failure as appropriate
Arguments
| :: Show a | |
| => [(a -> Bool, String)] | List of predicate functions and error messages, in case the predicate fails |
| -> a | The value |
| -> Failing a |
Apply multiple predicates to a value, return Success or all the Failure messages
checkM :: Monad m => Form xml m a -> (a -> m (Failing b)) -> Form xml m bSource
Add additional validation to an already validated component
Arguments
| :: Monad m | |
| => Env | A previously filled environment (may be empty) |
| -> Form xml m a | The form |
| -> (Collector (m (Failing a)), xml, FormContentType) |
Runs the form state
Instances
| (Functor m, Monad m) => Functor (Form xml m) | |
| (Monad m, Applicative m, Plus xml) => Applicative (Form xml m) |
