Re: [ANN] Cabal-3.6.0.0

Great news! The changelog (and the 3.6 branch) does not include https://github.com/haskell/cabal/pull/7493. This is just as well since HEAD (with this merge) doesn't fix the related issue in my testing, but I'm curious if such a fix can be part of a point release or if it must be 3.8? -Tom On

Re: Linking completely statically

I was able to get static linking working recently using docker alpine images and ghcup to install GHC based on the musl library. The details are in my Stan fork [1]. This borrowed heavily from ShellCheck's static linking release system except it uses cabal v2-build instead of v1. [1] Script:

Re: How to uninstall all cabal packages?

Packages registered with ghc are placed in the .ghc directory. You can delete the directory entirely or selectively unregister using ghc-pkg. On Dec 3, 2017 10:31 AM, "Volker Wysk" wrote: > Hi! > > I want to remove eveything which cabal has installed, and begin again with

Re: [Haskell-cafe] Splittable random numbers

Ryan, If you make an AES based RNG then consider making an instance for CryptoRandomGen (see DRBG [1] for example instances). Such an instance means you can use splitGen [2], which can split generators in the manner described in this thread. If you make the RNG match NIST SP 800-90 then feel

Re: backward compatibility

In my case I omitted BangPatterns from the pragma by accident and was thankful for the update. One slight benefit of the strict requirement of correct pragma is it's easier to survey Hackage to see how features are used, their popularity, and inform language design (ex: Garrett Morris's Haskell

ghc_rts_options (defalting RTS flags)

All, A recent SO question [1] led me to do a quick test on hard-coding RTS options as suggested in the manual rts-hooks section [2]. Unfortunately the timing tests indicate ghc_rts_opts isn't being used; tests with flags besides -N (ex: -H1024m) also show the ghc_rts_opts being ignored. Can

Re: what is the path to a particular module?

Is there a way from GHCi to discover the path to a particular module that you have imported or loaded? If you do ghci -v4 it will print out all the exposed modules right below the package that exposes them and the directory the package is in. You could just copy/paste this text and do a simple

Josh, In general you'll find the haskell-cafe (haskell-c...@haskell.org) to be a more lively place for this type of discussion, but since we're here I might as well mention that memory use of a Haskell function is one of the hardest things to gain an understanding about. main = print (show (sum
