Description
Synopsis
- parseDateMatcher :: String -> IO (CalendarTime -> Bool)
- data DateMatcher = Show d => DM String (Either ParseError d) (d -> CalendarTime -> Bool)
- getMatchers :: String -> IO [DateMatcher]
- testDate :: String -> IO ()
- testDateAt :: String -> String -> IO ()
Documentation
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.
Constructors
| 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.
