Config

Fields

• cfgPreserveIt :: Bool

  Preserve the it variable between examples (default: False)

• cfgVerbose :: Bool

  Verbose output (default: False)

• cfgModules :: [ModuleName]

  Module names to test. An empty list means "test all modules".

• cfgThreads :: Maybe Int

  Number of threads to use. Defaults to autodetection based on the number of cores.

• cfgRandomizeOrder :: Bool

  Randomize the order in which test cases in a module are run (default: False)

• cfgSeed :: Maybe Int

  Initialize random number generator used to randomize test cases when cfgRandomizeOrder is set. If set to Nothing, a random seed is picked from a system RNG source on startup.

• cfgQuiet :: Bool

  Only print error messages, no status or progress messages (default: False)

parseSeed :: String -> Maybe Int

Parse seed argument

>>> parseSeed "--seed=6"
Just 6
>>> parseSeed "--seeeed=6"
Nothing

parseThreads :: String -> Maybe Int

Parse number of threads argument

>>> parseThreads "-j6"

parseSpecificFlag :: String -> String -> Maybe String

Parse a specific flag with a value, or return Nothing

>>> parseSpecificFlag "--foo" "foo"
Nothing
>>> parseSpecificFlag "--foo=" "foo"
Nothing

Just "5"
>>> parseSpecificFlag "--foo=5" "bar"
Nothing

parseFlag :: String -> (String, Maybe String)

Parse a flag into its flag and argument component.

Example:

>>> parseFlag "--optghc=foo"
("--optghc",Just "foo")
>>> parseFlag "--optghc="
("--optghc",Nothing)
>>> parseFlag "--fast"
("--fast",Nothing)
