Re: [Nix-dev] Force Hydra to use localhost for building
Hi Nikolay,, Unfortunately, with distributed build enabled Hydra doesn't use its own server for building at all. it does, but only if all remote machines are busy. If you have build slaves with a configured maximum capacity of n jobs, then the n+1-th parallel build job (and all beyond that) will run on localhost. It's an imperfect situation.

Re: [Nix-dev] Vim conceal, cscope and other features
Hi,
Is there an easy way to
enable them (I know I can copy the nix file and edit it to my hearts
content, but I was hoping there is a better way)?
You could use `overrideDerivation` and hotfix the configureFlags. Grep for it
in nixpkgs/pkgs to see a few example.
There is an instructive one in pkgs/servers/x11/xorg/overrides.nix
let inherit (lib) overrideDerivation; in
# ...
darwinOtherX = overrideDerivation xorgserver (oldAttrs: {
# ...
configureFlags = oldAttrs.configureFlags ++ [
--disable-xquartz
--enable-xorg
--enable-xvfb
--enable-xnest
--enable-kdrive
];
# ...
});
Best, Andreas

[Nix-dev] Introducing nox and nox-review
Hello everyone. I just realized I've never properly announced nox on the mailing list, so here it comes. I'm happy to present the nox tools suite, which is a set of tools designed to improve the use of Nix and NixOS. The code can be found at https://github.com/madjar/nox, and nox is available in nixpkgs as the nox attribute. There are already two tools that should make your life easier. nox itself is a command line tool that help you search nixpkgs to install packages. It's basically a nicer version of the old nix-env -qaP | grep, with caching to make search faster, color, and a few other niceties. nox-review is a tool designed to help those who work on nixpkgs. nox-review pr PR_NUMBER downloads a pull request, merges it in master, and build every single path affected by the pull request (each package changed by the pr, and all their dependencies). This makes it easy for a reviewer to build a pull request before merging it, and allow them to make sure that nothing unexpected was broken by a pull request. nox-review wip, on the other hand, can be used to make sure the changes introduced in a nixpkgs working tree don't break anything. I hope you can make a good use of those tools, especially nox-review pr which I hope can improve the reliability of nixpkgs by making it easier to catch breakage early.

[Nix-dev] Fwd: Haskell doctest
Ah sorry, I wrote that on my phone so the answer was a bit short :).
You just type eval $buildPhase while you're in nix-shell. eval is a bash
builtin to execute a bash script from a string, and the buildPhase
environment variable contains the script that nix would use to build your
project when you'd use nix-build or similar. So eval $buildPhase just
builds your project but it also sets the GHC_PACKAGE_PATH environment
variable at the end, so that the tests can find the packages.
Since nix uses the `Setup.hs` file directly instead of going through
cabal-install, you will need to run eval $configurePhase once so that
Setup.hs gets compiled into the Setup executable and the project is
configured.

and where I would put that. I'm stilling finding my feet with nix. :)

Hello Rich,
GHC_PACKAGE_PATH needs to be set correctly for doctests to work. The
problem with this is that cabal doesn't work with GHC_PACKAGE_PATH set, so
you can't set it permanently.
If you use eval $buildPhase, that will build the project and set
GHC_PACKAGE_PATH. doctests should work after that. You might need to run
eval $configurePhase before though, to compile Setup.hs.

For the nix newbies like me, could you please expand upon If you would like to use our branch you should add hydra.joelt.io to your binary caches. You want to set the binary-caches option in nix.conf, e.g. binary-caches = http://cache.nixos.org http://hydra.joelt.io I think nix looks for /etc/nix/nix.conf by default, but this is configurable via the NIX_CONF_DIR environment variable.
