I would have like to use vector-random and got this :
Data/Vector/Random/Mersenne.hs:33:18:
Could not find module ‘Data.Vector.Fusion.Stream’
It is a member of the hidden package ‘vector-0.10.12.3@vecto_1COyUuV1LrA1IjYnWfJnbs’.
Perhaps you need to add ‘vector’ to the build-depends in your .cabal file.
Use -v to see a list of the files searched for.
Data/Vector/Random/Mersenne.hs:35:18:
Could not find module ‘Data.Vector.Fusion.Stream.Size’
It is a member of the hidden package ‘vector-0.10.12.3@vecto_1COyUuV1LrA1IjYnWfJnbs’.
Perhaps you need to add ‘vector’ to the build-depends in your .cabal file.

I wouldn't be opposed to fixing it, but I'm wondering at this point there isn't a better package to use instead.
I'm looking for both integer and floating point random numbers, uniform and gaussian.
gsl-random looks promising as does mwc-random.
any other suggestions ?
Thanks,
Brian

Have you tried adding the vector package to the build-depends to you
cabal file as suggested in that error message?

I like tf-random for its functional interface and splittable design. But
I have only judged subjectively. And it only does uniform.

No. it looked very old and out-of-date, so I thought i would see what other recommendations people had.

Do you think it's fixable by going through and updating pragmas and such, or does it require a more involved rewrite ?
It's been well over a year since I was looking at RNGs and I'm not sure I trust my instincts from that far back, but my pick at the time was pcg-random: https://hackage.haskell.org/package/pcg-random

Thanks. I hadn't seen that one.

I'll definitely give it a try.
Thanks.
