checkFor :: Testable a => Int -> a -> IO ()leancheck Test.LeanCheck.IO Check a property for a given number of tests printing results on stdout
> checkFor 1000 $ \xs -> sort (sort xs) == sort (xs::[Int]) +++ OK, passed 1000 tests.
Test exhaustion is reported when the configured number of tests is larger than the number of available test values:> checkFor 3 $ \p -> p == not (not p) +++ OK, passed 2 tests (exhausted).
checkResultFor :: Testable a => Int -> a -> IO Boolleancheck Test.LeanCheck.IO Check a property for a given number of tests printing results on stdout and returning True on success.
> checkResultFor 1000 $ \xs -> sort (sort xs) == sort (xs::[Int]) +++ OK, passed 1000 tests. True
There is no option to silence this function: for silence, you should use holds.iso8601DateFormat :: Maybe String -> Stringtime-locale-compat Data.Time.Locale.Compat Construct format string according to ISO-8601. The Maybe String argument allows to supply an optional time specification. E.g.:
iso8601DateFormat Nothing == "%Y-%m-%d" -- i.e. YYYY-MM-DD iso8601DateFormat (Just "%H:%M:%S") == "%Y-%m-%dT%H:%M:%S" -- i.e. YYYY-MM-DDTHH:MM:SS

readPackageDbForGhc :: FilePath -> IO [DbUnitInfo]ghc-boot GHC.Unit.Database Read the part of the package DB that GHC is interested in.
-
ghc-boot GHC.Unit.Database Read the part of the package DB that ghc-pkg is interested in Note that the Binary instance for ghc-pkg's representation of packages is not defined in this package. This is because ghc-pkg uses Cabal types (and Binary instances for these) which this package does not depend on. If we open the package db in read only mode, we get its contents. Otherwise we additionally receive a PackageDbLock that represents a lock on the database, so that we can safely update it later.
