Mathematics utilities for Haskell

Latest on Hackage:0.9.2

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow to host generated Haddocks.

Build Status

What is this?

This repo contains functions to help in mathematics calculations or puzzles using Haskell. Currently there is only one module, Numeric.Euler.Primes, which contains implementations of three prime number sieves:

The current major version (0) is stable enough to be used for Project Euler problems but keep in mind that the sieves are still not optimized at all. I've been mostly busy trying to make a stable build.

You can also find this package in Hackage.

Dependencies and building

To install the library you just need the latest base, so GHX 7.8 should be more than enough. Just cabal install euler from you project or add euler as a dependency to your .cabal file and you should be good to go.

If you want to build the library locally, you'll need a few more things:

Building with cabal

You'll need:

  • GHC >= 7.8
  • cabal-install == 1.22.*
  • happy == 1.19.* to run HLint

cabal-install will take care of installing all the other dependencies. Happy is an executable so you need to get either to you user space or through you OS package manager. You then build it like this:

git clone
cd euler
cabal sandbox init
cabal install --only-dependencies --enable-tests --enable-benchmarks --enable-library-coverage
cabal build
cabal test
cabal bench

Building with runhaskell

You'll need:

  • happy == 1.19.* and hlint == 1.9.* to run HLint;
  • hspec == 2.1.* to run the unit tests;
  • xml == 1.3.* to run the unit test coverage;
  • regex-posix == 0.95.* to run the documentation coverage;
  • criterion == 1.0.2.* to run the benchmarks.

You need to get these yourself since building it with runhaskell will not get these dependencies for you. As far as I know. You then build it like this:

runhaskell Setup.hs configure --enable-tests --enable-library-coverage --user
runhaskell Setup.hs build
runhaskell Setup.hs test
runhaskell Setup.hs bench

Happy hacking! :-)
