parseDateMatcher :: String -> IO (CalendarTime -> Bool)Source
parseDateMatcher
s
return the first matcher in
getMatchers
that can parse s
data DateMatcher Source
A DateMatcher
combines a potential parse for a date string
with a matcher function that operates on a given date.
We use an existential type on the matcher to allow
the date string to either be interpreted as a point in time
or as an interval.
forall d . Show d => DM String (Either ParseError d) (d -> CalendarTime -> Bool) |
getMatchers :: String -> IO [DateMatcher]Source
getMatchers
d
returns the list of matchers that will be
applied on d
. If you wish to extend the date parsing code,
this will likely be the function that you modify to do so.
