[Nix-dev] The Future of Haskell Packaging in Nix

Fellow Nixers and Haskellers, the Haskell NG effort [1] allowed us for the first time to distribute the latest version of every package known to Hackage -- well over 8,000 builds in total --, and this seemed like a crazy leap forward at the time. These days, we distribute 60+ Haskell package sets

[Nix-dev] [***SPAM***] Use Function Application To Escape Override Hell

The Problem --- The architecture of the haskell.packages.* hierarchy worked fine when Nixpkgs shipped a handful of manually maintained package sets. The addition of LTS Haskell, however, increased the number of active package sets by a factor of 10, and that number will grow further since

[Nix-dev] How to configure neovim?

Hi, the neovim derivation seems to be customizable like the vim_configurable expression - but how do I actually do that from my configuration.nix? I have (a bit stripped): let # [...] custom_vim= pkgs.vim_configurable.customize { name = "vim";

You need to create such function. Take a look at [1]. [1] https://github.com/NixOS/nixpkgs/blob/master/pkgs/misc/vim-plugins/vim-utils.nix#L281 2015-10-14 21:40 GMT+03:00 Matthias Beyer : > Hi, > > the neovim derivation seems to be customizable like the > vim_configurable

[Nix-dev] attribute 'replaceStrings' missing??

Maybe something was corrupted. Check nix-store with `sudo nix-store --verify --check-contents --repair`. 2015-10-15 0:25 GMT+03:00 Christopher Rooney : > I updated for the first time in a while (from generation 23 to 24). I got > an error on most common uses of

Re: [Nix-dev] hydra build failures

It's really sad to me that we have Nix as a core tool to solve packaging problems and then we don't even release hydra and claim minimum versions required for it's dependencies. It gives a really bad taste to anyone who tries Nix stack and gets bitten on such trivial problem we claim to solve.

Re: [Nix-dev] hydra build failures

Thanks. There are various companies/people using it in the wild, I see no reason why we couldn't release an alpha, just so people can install it successfully. On Wed, Oct 14, 2015 at 1:24 PM, Eelco Dolstra wrote: > Hi, > > On 14/10/15 13:01, Domen Kožar wrote: > >

Vladimir, that did the trick, thanks. Arseniy, I did have a bad hash, so thanks for that, even though it didn't solve the pressing problem. On Wed, Oct 14, 2015 at 5:16 PM, Vladimír Čunát wrote: > Hi. > > On 10/14/2015 11:25 PM, Christopher Rooney wrote: > > I updated for the
