[Nix-dev] Recent change to stdenv in 4cb43d2
My apologies to all for changing stdenv everwhere by merging 4cb43d2 without waiting to batch it with other, pending stdenv changes. It was a minimal, correct fix to the way ppl is compiled, but shouldn't have been merged in by itself. If it should be reverted, can someone please do so?

No worries, I didn't mean to be offensive. This is not about my experience, but about my opinion, and I'm just stating that we do not have to follow the lead of large websites, particularly since the goal of our website is to convey useful information. It does not provide a web service in the traditional sense. The new website does have a few new features, but most of them look like stopgaps to me, like the commit history, which isn't really useful on the home page. I would prefer the subprojects themselves to take most of the space with a very short introduction at the top.

Re: [Nix-dev] myEnvFun for IPython with Nix on openSuse host
Dear Luca,
Thanks for your response.
> What commit of nixpkgs are you tracking?
How do I find that out?
I installed Nix using the install script, not the from source installation.
So, I never manually checked out any package list.
I ran the following commands. They didn't really do anything. In my
interpretation that means, that my Nix installation should already be
up-to-date. Correct?
$ nix-channel --list

$ nix-channel --update

[Nix-dev] myEnvFun for IPython with Nix on openSuse host
Hi everyone,
I am very new to Nix, so let me apologize in advance if this ends up being
a stupid question.
# First, some back story:
The reason I got interested in Nix is that I am doing scientific computing
on a number of different machines with self-made simulation software.
Hence, I need to keep my development environments in sync on these various
machines. A tiresome task that, so far, I am performing manually. I
understand that Nix is promising to help in such situations.
So, I went ahead and installed Nix in single user mode on my laptop which
is running on openSuse 13.1. That is, I used the install script [1], and
installed Nix under /nix. On the wiki I found a section [2] about managing
development environments, which introduces a thing called myEnvFun. It
worked out for a simple environment to use numpy:
numpy = pkgs.myEnvFun {
name = "numpy";
buildInputs = with pkgs; let p27=python27Packages; in [
stdenv python
p27.readline
p27.numpy
];
};
I've installed it using `nix-env -i env-numpy`, and loaded it using `
load-env-numpy`, and everything seems to work fine.
$ load-env-numpy
env-numpy loaded
$ which python
/nix/store/qikwsrbsyx59ygcmb36p1rgmfclgg882-python-2.7.6/bin/python
$ python
Python 2.7.6 (default, Apr 21 2014, 11:09:09)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy.version
>>> numpy.version.version
'1.7.1'
However, I would prefer to do develop using the IPython shell. So, I wrote
another environment that encorporates ipython:
ipython = pkgs.myEnvFun {
name = "ipython";
buildInputs = with pkgs; let p27=python27Packages; in [
stdenv python
p27.readline
p27.ipython
p27.numpy
];
};
Installing it works just fine. Loading the environment on the other hand
doesn't.
# The Problem
I get a huge amount errors about gdk-bug when I load the ipython
environment defined above:
$ load-env-ipython
mkdir: cannot create directory ‘/lib/gdk-pixbuf-loaders-2.0/’:
Permission denied
# repeated 61 times
mkdir: cannot create directory ‘/lib/gdk-pixbuf-loaders-2.0/’:

Permission denied
# repeated 17 times
mkdir: cannot create directory ‘/lib/gdk-pixbuf-loaders-2.0/’:
Permission denied
env-ipython loaded
Depsite the error messages, the environment seems to work.

In [2]: numpy.version.version
# My Question
What is going on there? Is this because I'm using Nix on a host OS, instead
of NixOS?
Or, am I just missing some package in the environment? In which case,
shouldn't Nix take care of this, and make sure all dependencies are
available?
One instance of a kind-of missing dependency is already the readline
module. If I don't mention it explicitly in the environment, python is
going to complain about it missing.
Thanks in advance for your help. And also thanks for doing this project in
the first place.
Best regards,
Andreas

[Nix-dev] Getting nix-shell to consider config.nix
My ~/.nixpkgs/config.nix is as follows:
###
{ pkgs }:
{ packageOverrides = self: with pkgs; rec {
ghc = self.ghc // {
ghcHEAD = callPackage /home/shana/programming/ghc {};
};
}; }
###
What I think it does is overrides ghcHEAD packages with the package I
have in the specified path. In fact, nix-env -qaP | egrep -i ghcHEAD
shows: nixpkgs.ghc.ghcHEAD ghc-7.9.20140530
This is consistent with the version in my default.nix at the specified path.
Now I want to use this in another project, through nix-shell (and
otherwise).
At the top of it I have
###
{ haskellPackages ? (import {}).haskellPackages_ghcHEAD
, …
}:
###
But that wants to pull in 7.9.20140430 which is what ghcHEAD version is
in nixpkgs itself so clearly it's omitting my config.nix. How can I get
nix-shell to look in my config? I tried playing with variety of --arg
stuff but no matter what I try, it tells me that ~/.nixpkgs/config.nix
doesn't exist so I must be using it wrong.
