Re: Are constructors matched against using "switch" or chained if-else

That answer (which I did indeed write once upon a time) is somewhat incomplete. Case matches on Ints actually work in about three different ways: 1. Linear search 2. Binary search 3. Jump table There's some amount of mix and match available for gappy things. I don't know all the details. As for

Re: Are constructors matched against using "switch" or chained if-else

Thanks David. Can I ask why? Is it because the first constructor is treated specially? (perhaps because it has zeroed tag bits)? Or is it just because there's always an if/else chain in order of the constructor definition regardless of the order of the case statement so the higher up the list the

Re: Are constructors matched against using "switch" or chained if-else

I can answer one of your questions for sure: the order of your case branches doesn't matter at all. However, the order of the data constructors in the type declaration does matter. Put your most likely one first. On Tue, Feb 22, 2022, 9:09 PM Clinton Mead wrote: > Hi All > > I'm developing an

Are constructors matched against using "switch" or chained if-else

Hi All I'm developing an unbounded integer type, which I won't go into the details here but in some circumstances has better performance than the standard "Integer". Anyway, whilst there are complex cases, the most common case is a standard machine int multiplication. Hence I want the type to

Thanks Gergö, I do find Richard's tendency to use ViewPattern examples distracts me from understanding the point. That arrow-to-nowhere or arrow-to-the-wrong-value syntax is nausea-inducing. Your "instructive" example is really nothing to do with PatSyns, just ordinary Haskell numeric patterns:

Re: osx conundrum

I’m a maintainer of the MacPorts ghc port. The MacPorts installations do not have this issue, whether installed from the buildbot binaries or compiled from source, that all work on multiple macOS versions 10.9–11. Here’s the build recipe:

Thanks Dominic George for that. I had env var set. iconv --version gives GNU libiconv 1.16 I created a clean shell so env vars set other than PATH and installed using the tarball on the link George provided. It appeared to install okay . However trying to compile throws up: cannot satisfy

Re: Glasgow-haskell-users Digest, Vol 212, Issue 5

Hi David I've also used ghc for years on Mac OS and have also never seen this problem. I don't use nix. Currently I am on ghc 9.0.1. and Mac OS 11.6. I installed from https://downloads.haskell.org/ghc/9.0.1/ More specifically ghc-9.0.1-x86_64-apple-darwin.tar.xz

Re: osx conundrum

Never met this issue myself (with currently osx 10.14.6 Mojave, and a few previous versions), I guess macports/homebrew or some other pieces aren't playing nicely with some others in your machine. Checkout https://newbedev.com/libiconv-or-iconv-undefined-symbol-on-mac-osx

Re: osx conundrum

I'd recommend to search for iconv library in your packaging system. Find that and install that. Probably it looks like dependency on this is missing in provided ghc package(s). Anyway, not osx user here, just general unix user... Good luck! Karel On 10/11/21 11:00 AM, David Duke wrote: > I

osx conundrum

I have a conundrum on which advice would be appreciate. Does anyone know how to successfully install ghc on OSX I've tried various binary instalation routes: macports, brew, direct binary downloads from haskel.org All have the same result. when I try to compile a basic hello world program I get
