Re: [Nix-dev] Best practices for replacing channels with my own package set?
Hmm I have that too but it doesn't work. Is yours like this (with myhead
for mypkgs)?
$ ls ~/.nix-defexpr/ -al
...
lrwxrwxrwx 1 jefdaj users 22 Apr 17 10:46 mypkgs -> /path/to/mypkgs
...
I think I found the other/main problem: `NIX_PATH` isn't
sticking during `nixos-rebuild` because I put it in
`environment.variables` instead of `environment.sessionVariables`. I
guess it's normally set in both and `sessionVariables` takes priority?
If I set it in the shell with `export NIX_PATH=...` then `nix-env`
works again. It also works when placed in `sessionVariables` as Herwig
said, but that causes other havoc (messing up the locale etc.):
with import ;
{
...
environment.sessionVariables = lib.mkForce {
"NIX_PATH" = "/path/to/mypkgs";
};
...
}
Am I looking for a way to union that with the defaults or maybe
`mkForce` a single attribute?

Re: [Nix-dev] nix-shell for a custom haskell library
Dmitry Malikov writes:

> basing on a tutorial by Oliver Charles
> (http://wiki.ocharles.org.uk/Nix).
FWIW I've been playing with Nix and Haskell a lot lately trying to come
up with the perfect development environment. This is what I have so
far. Everything below is done with a recent copy of nixpkgs.
I have a shell function called nix-hs-build that does the following:
# Create a default.nix for the Haskell project in $PWD:
nix-shell -p haskellPackages.cabal2nix \
--command "cabal2nix $PWD $@ > default.nix"
# Build the project:
nix-hs-shell --command $(which hsbuild.sh) "$@"
The contents of hsbuild.sh can be found here:
https://gist.github.com/pjones/7a6023d3567ff2ed49bf
The `nix-hs-shell` command is another shell function that just runs
nix-shell with cabal-install and hlint in the environment so that
hsbuild.sh can work. Here are the details:
function nix-hs-shell () {
override=~/.nixpkgs/envs/dev/haskell-cabal.nix
nix-shell -I pwd=$PWD --pure "$@" $override
}
Where haskell-cabal.nix contains:
{ nixpkgs ? import {}
, compiler ? "ghc7101"
}:
let
pkgs = nixpkgs.pkgs;
ghc = pkgs.haskell.packages.${compiler};
f= import ;
drv = ghc.callPackage f {};
in
(pkgs.haskell.lib.addBuildTools drv [
ghc.cabal-install
ghc.hlint
]).env
With those pieces I can just run `nix-hs-build` without having to create
any sort of *.nix file by hand. If I change the project's cabal file
and run `nix-hs-build` it will work since it generates the default.nix
again. I can also change compilers with a flag:
nix-hs-build --compiler ghc784

Using my setup above, the library would be installed in ./dist

[Nix-dev] Best practices for replacing channels with my own package set?
I'd like all the nix tools to reference my package repository, which is called mypkgs and re-exports nixpkgs with some custom ones added. I base it on the latest nixos-unstable revision so there should be binaries available. Currently I set NIX_PATH using `environment.interactiveShellInit`. That seems to work for everything except nix-env, so I alias it to `nix-env -f /path/to/mypkgs`. But I'm a little worried there might be parts of the system still depending on ~/.nix-defexpr, /etc/nixos etc. Anything else I should be doing?

It's not enabled by default. You need to set NIX_SUBSTITUTERS to include copy-from-other-stores.pl. Check out the NixOS installer, which uses it to ensure that binaries are copied from the installation CD: https://github.com/NixOS/nixos/blob/master/modules/installer/tools/nixos-install.sh However, NIX_OTHER_STORES might be removed at some point because it doesn't work well anymore for access to remote stores since Nix started used SQLite. -- Eelco Dolstra | LogicBlox, Inc. | http://nixos.org/~eelco/ ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev

Yes, I guess so. Even though I'm not quite sure why you'd want to re-define hackage-packages.nix to begin with. Wouldn't it be easier to customize the existing package set to your needs rather than re-defining it from the ground up?
