addForeignSource :: ForeignSrcLang -> String -> Q ()template-haskell Language.Haskell.TH.Syntax Emit a foreign file which will be compiled and linked to the object for the current module. Currently only languages that can be compiled with the C compiler are supported, and the flags passed as part of -optc will be also applied to the C compiler invocation that will compile them. Note that for non-C languages (for example C++) extern C directives must be used to get symbols that we can access from Haskell. To get better errors, it is recommended to use #line pragmas when emitting C files, e.g.
{-# LANGUAGE CPP #-} ... addForeignSource LangC $ unlines [ "#line " ++ show (844 + 1) ++ " " ++ show "libraries/template-haskell/Language/Haskell/TH/Syntax.hs" , ... ]qAddForeignFilePath :: Quasi m => ForeignSrcLang -> String -> m ()template-haskell Language.Haskell.TH.Syntax No documentation available.

filepath System.OsPath.Types Ifdef around current platform (either WindowsPath or PosixPath).
isLeafOrCollision :: HashMap k v -> Boolunordered-containers Data.HashMap.Internal -
tasty-quickcheck Test.Tasty.QuickCheck Optional; used internally in order to improve shrinking. Tests a property but also quantifies over an extra value (with a custom shrink and show function). The Testable instance for functions defines propertyForAllShrinkShow in a way that improves shrinking.

HUnit Test.HUnit.Base Performs a test run with the specified report generators. This handles the actual running of the tests. Most developers will want to use HUnit.Text.runTestTT instead. A developer could use this function to execute tests via another IO system, such as a GUI, or to output the results in a different manner (e.g., upload XML-formatted results to a webservice). Note that the counts in a start report do not include the test case being started, whereas the counts in a problem report do include the test case just finished. The principle is that the counts are sampled only between test case executions. As a result, the number of test case successes always equals the difference of test cases tried and the sum of test case errors and failures.
performTestCase :: Assertion -> IO ResultHUnit Test.HUnit.Lang Performs a single test case.

random System.Random The class of types for which a uniformly distributed value can be drawn from all possible values of the type.

random System.Random The class of types for which a uniformly distributed value can be drawn from a range.
uniform :: (RandomGen g, Uniform a) => g -> (a, g)random System.Random Generates a value uniformly distributed over all possible values of that type. This is a pure version of uniformM.
Examples
>>> import System.Random >>> let pureGen = mkStdGen 137 >>> uniform pureGen :: (Bool, StdGen) (True,StdGen {unStdGen = SMGen 11285859549637045894 7641485672361121627})
