Property-based testing with internal integrated shrinking This library provides property based testing with support for internal integrated shrinking: integrated in the sense of Hedgehog, meaning that there is no need to write a separate shrinker and generator; and internal in the sense of Hypothesis, meaning that this works well even across monadic bind. However, the actual techniques that power falsify are quite different from both of these two libraries. Most users will probably want to use the integration with tasty, and use Test.Tasty.Falsify as their main entrypoint into the library. The Test.Falsify.Interactive module can be used to experiment with the library in ghci.

Integer-to-digits conversion. Convert an integer to digits and back. This library is both asymptotically (O(n^1.4) vs. O(n^2)) and practically (2x-40x for typical inputs) faster than Data.Digits.

Non IEEE-754 compliant compile-time floating-point optimisations The Numeric.FastMath module brings into scope many unsafe RULES for Floats and Doubles that can greatly improve run time performance. It is roughly equivalent to gcc's -ffast-math compiler flag. Optimisation (at least -O1) must be enabled for any RULES to take effect. These rules are unsafe because they don't strictly adhere to the IEEE-754 regulations and may subtly change the results of your numeric computations. See the README on github for more details.

Family of families: featherweight defunctionalization Promote regular type families to first-class, without polluting the type namespace. See README.

Low-level interface to FFTW (Fast Fourier Transform) FFTW claims to be the fastest Fourier Transform in the West. This is a low-level interface to libfftw. We re-use the type classes from netlib-ffi. See also package fft.

A cache system associating values to files. A cache system, that works by associating computation results with file names. When the files are modified, the cache entries are discarded.

Filterable request logging wai middleware. Change how data is logged and when. Composable filters to transform objects and control when they are written to server logs.

refining property sets for testing Haskell programs FitSpec provides automated assistance in the task of refining test properties for Haskell functions. FitSpec tests mutant variations of functions under test against a given property set, recording any surviving mutants that pass all tests. FitSpec then reports:
- surviving mutants: indicating incompleteness of properties, prompting the user to amend a property or to add a new one;
- conjectures: indicating redundancy in the property set, prompting the user to remove properties so to reduce the cost of testing.
