With the module system, mkMerge is the preferred variant
<pie__>
the reason i split it up like that was because i wanted to do a let but not pollute the namespace for the first set
<infinisil>

makes sense i guess

now i feel dumb

"{ _type = \"merge\"; contents = [ { x = ...; } { c = ...; e = ...; } ]; }"
<infinisil>
this hah
<pie__>
ok so just use mkmerge then
<pie__>
instead of //
<infinisil>
Yeah, with the module system that's the best choice
<pie__>
they are both ugly but fiiiine :P
<infinisil>
Well you can always add more let in's and newlines
<infinisil>
let secondpart = let y = 20; in { c = y; .... }; in lib.mkMerge ...
<pie__>
im an idiot, maybe i should just make another file
<infinisil>
I usually don't care about polluting namespaces, I don't have that much variables. So I just use a single big let in at the beginning for everything
<infinisil>
Yeah or that

hello, I've made the jump today to install NixOS and so far things have been fairly smooth. But I run into an issue that I'm not sure can be fixed. I have to work with tensorflow in a virtualenv and the wheel contains a prebuilt binary. I understand you can use patchelf to fix this but how can I find the needed files and what kind of fix do I need to apply? Everything I've found on google shows up in nix

<worldofpeace>
actually wait, I don't know what I'm talking about. You don't need virtualenv. You should read the python section in the nixpkgs manual I think.
<Baughn>
It isn't impossible, but you'll have to patch the binary manually.
<Baughn>
And if it's the GPU version... might as well be.
<Baughn>
You'll find NixOS much more comfortable if you go all-in.
<numkem>
how would i proceed than? Scrap virtualenv and do... nix containers? I have yet to graps the whole thing but I think I understand the basics
ggp0647 has joined #nixos
<Baughn>
Not containers, no.
<truthadjustr>
actually,.. is why i resort to docker when things get rough in nixos
<numkem>
virtalenv by design does somewhat was a nix package does which is nice, but in the case of development, if i could get a /bin/python out of something I could direct emacs to it and it would work i believe
<numkem>
truthadjustr: but than having to rebuild everytime you make a fix gets tedious... I guess a volume could solve a big part of it
<numkem>
I'll read the doc, maybe there is an eaiser way
<Baughn>
When you put "python35.withPackages (...)" in a shell.nix and run nix-shell, what it does is build a wrapper for python + the named packages.
<Baughn>
Which sets the various path environment variables in a manner very reminiscent of virtualenv.

This is how basically all runtime dependencies work in NixOS, for everything where they can't just be baked into the binary with absolute paths.
<numkem>

spacefrogg has joined #nixos
woodson has joined #nixos
<Baughn>
numkem: My favorite use of it is to make "portable shell scripts". Using #!/usr/bin/env nix-shell instead of #!/bin/bash, I can get Nix to install any dependencies for the script on-demand.
<numkem>
wonder if I could write an env.py that would do a nix-shell through the shebang so emacs can auto-complete with it
<Baughn>
...but that also works for python scripts and so forth.
<Baughn>
It's nice having it all in one file.
<Baughn>
Hmm. LSP not an option?
<numkem>
LSP?
<Baughn>
Language server protocol
<Baughn>
If you need *that particular* python to be in the PATH for Emacs... guess the simplest way would be to launch Emacs from nix-shell.
<Baughn>
Which is how you'd have to do it if using virtualenv, right?
<numkem>
it's using anaconda in the backend
<numkem>
well virtualenv exposes a bin/python and emacs supports virutalenvwrapper
<Baughn>
Not familiar with anaconda.
<Baughn>
Doesn't seem to exist as a package, either.
<Baughn>
...anyway, gtg. GL.
<numkem>
if nix-shell actually writes something somewhere and I can track it down it would be doable I believe
<numkem>
Baughn: thank you
<Baughn>
nix-shell puts various things in the environment.
<Baughn>
There's certain to be ways to do what you want to do. Multiple. Some better than others.

hi, I'm using nixpks on top of another distribution and I've started doing declarative package management using config.nix – it feels much better than installing stuff ad hoc but I'm still missing some things
<tlotze_>
installing packages directly into the environment allowed me to see the currently installed versions using nix-env -q; how do I achieve the same if all nix-env -q gives me is my "myPackages" package that pulls in the real stuff?
<srhb>
tlotze_: I'm afraid you don't really. But exploring the files in the profile you should be able to find every store path that is included, though that includes (transitive) dependencies as well.
tzemanovic has quit [Ping timeout: 248 seconds]
<srhb>
At least in some cases.
<tlotze_>
hm, I was afraid it would take some digging
<tlotze_>
so there isn't even a better way to find out the version of a single package that has been pulled in transitively?
<srhb>
tlotze_: None that I know. fwiw I would just keep myPackages up to date and evaluate any versions from nixpkgs directly.
<srhb>
Rather than considering the installed versions special.
<tlotze_>
ok
<tlotze_>
another thing
<srhb>
tlotze_: Perhaps you could make your life easier by generating a version list automatically to include in your myPackages
<tlotze_>
oh
<srhb>
tlotze_: Like, you could map over every package and create a pseudopackage that is just a text file containing name-version
<tlotze_>
how does that work conceptually? I'm using channels so I could pin channels to a version, but how could I freely pin versions of packages?
<tlotze_>
other that copying their definition, that is
<srhb>
tlotze_: I'm not talking about pinning, I'm just talking about recording the versions in any one generation of myPackages
<tlotze_>
just as documentation, you mean?
<srhb>
essentially let myPkgs = [ your list of packages ]; in myPkgs ++ [ (package that records name-version of all packages in myPkgs) ]
<srhb>
tlotze_: Yeah
<tlotze_>
to be honest, I'm not sure what that "package that records the versions" would b
<tlotze_>
e
<srhb>
tlotze_: A text file, essentially. But perhaps it doesn't help you. Not sure what you're trying to achieve exactly. :)
<tlotze_>
All I want to achieve is if I need to know which version of a package I use (say, because something doesn't work and I want to check whether I'm using a version with a particular bug already solved), and the program doesn't tell me easily itself, I want to find out by asking the package manager.
<tlotze_>
but I think it's ok to do some digging in such cases, at least for now
<tlotze_>
it's not that it couldn't be done, it just feels like it should be easy and I'm missing something
<tlotze_>
but I do understand that with declarative package management, all my installed packages become just dependencies

even better: find /nix/store/*-my-packages -type l -printf '%l\n' |sed 's/[^-]*-//' |sed 's+/.*++' |sort |uniq

<srhb>
tlotze_: Like import (fetchurl (url-of-tar.gz-)) {}
<tlotze_>
well, I'd like to benefit from version updates in the channels, and I'd like to use current stuff, but once in a while something doesn't work and I need to fall back to an older, stable channel
<srhb>
tlotze_: Right. I find that easier to fix by managing the imports directly and bumping as needed
<JasonGrossman>
woffs: I've been planning to try ZFS encryption. Will test.
<JasonGrossman>
woffs: Thanks for your work.
<tlotze_>
srhb: a current example is to use libreoffice-fresh from 18.03 rather that libreoffice from unstable; it's almost as current, does work, and will probably be updated anyway
<srhb>
tlotze_: Yeah.
<tlotze_>
srhb: thank you for your answers, that was quite insightful
<srhb>
tlotze_: So I'd have pkgs1803, pkgsUnstable and maybe pkgsMaster all defined, then I can switch easily between which is used. of course, you can also easily do this with channels if you want. Not sure how you're achieving it currently.
<srhb>
I assume something like unstable = import <nixpkgs-unstable> {}; with nixpkgs-unstable defined as a channel name tracking the unstable branch..
<tlotze_>
almost
<tlotze_>
in my case, unstable is the default and 18.03 is explicitly listed as stable and imported by that name
<srhb>
Right.

<tilpner>
(It's working, but doing the wrong thing)
<tilpner>
chrisaw - Just to make sure, default.nix is a module that you have imported into your NixOS configuration, right?
<chrisaw>
tilpner: the strange thing is - even if I install it using: nix-env -iA nixos.python3Packages.warrant - it still doesn't apply the patch.
<chrisaw>
tilpner: correct
<kreetx>
booglewoogle: haha
<tilpner>
chrisaw - That's expected, nixpkgs.overlays does not affect nix-env by default (though it can be made to do so)
<chrisaw>
tilpner: Ahh ok! That explains that one then.
<tilpner>
(nix-env is weird and should be avoided if possible IMO)
<kreetx>
booglewoogle: as far as my nix-fu has taken me, expressions with certain structure (type) need to be at the correct places, and then everything works, otherwise explodes
<booglewoogle>
for example, how would i go about installing ghc-mod in that environment? if you happen to know
<kreetx>
booglewoogle: if the language were typed, the compiler would tell you, atm the runtime tells you
<tilpner>
chrisaw - And nixos-option nixpkgs.overlays confirms that there are as many overlays as you are trying to set?
<chrisaw>
tilpner: Sorry, you've lost me there. As in - the overlays I'm setting actually exist? If so, yes.
<kreetx>
booglewoogle: do you mean in the context of shell.nix -- i.e at dev time?
<tilpner>
chrisaw - Run "nixos-option nixpkgs.overlays"
<booglewoogle>
i suppose, yeah
<chrisaw>
tilpner: "Value:" - nothing output. Strange because I actually have 3 package overlays for individual packages and the other 2 are working great. Just this one isn't.
<chrisaw>
tilpner: Oh just a sec - verbose tells me it can't parse one.
<truthadjustr>
tilpner: thanks.. how to find possible values for virtualisation.virtualbox.host.enableExtensionPack? tried to google, tried 'true' but it's not accepting
<tilpner>
truthadjustr - true and false, none other should be accepted
<booglewoogle>
i'm just trying to put the pieces of what's happening here at all together. new to both nixos and haskell (or developing at all really)
<chrisaw>
tilpner: Typo in one of them while I was experimenting. Fixed that. Result is now: 3
<booglewoogle>
seems hard to find comprehensive and up-to-date info about this otherwise :p
<chrisaw>
Which is the same amount as I actually have
<tilpner>
chrisaw - Now the nixos-rebuild again, I guess?
<truthadjustr>
tilpner: 'virtualisation.virtualbox.host.enableExtensionPack = true;' is not accepted either
ivanfon[m] has joined #nixos
<tilpner>
Ah, it's recent
<chrisaw>
tilpner: Same error from the pkg: "ModuleNotFoundError: No module named 'pip.req'" - that's beause it needs the pip10 support patch which is what I'm trying to apply. :)
<kreetx>
booglewoogle: (I don't use it myself, don't run nixos as my dev machine, etc, but:) I think you need to find a way to do something in the lines of 'nix-env --install ghc-mod'
<kreetx>
it didn't work for me just now, but somehow the installing of haskell executables needs to be possible
<tilpner>
truthadjustr - It's only available on nixos-unstable
<kreetx>
since it's on hackage, it pretty much needs to be in nix's haskell packages
<kreetx>
booglewoogle: learning haskell and nix together seems quite a combination -- hope you're on a tight deadline also :p
<tilpner>
chrisaw - I'll be gone for ~40min, can try again afterwards
<booglewoogle>
yeah, makes sense. i'll try
<booglewoogle>
kreetx: haha, nah, nothing like that at all, that's just out of private interest
<kreetx>
booglewoogle: either you install ghc-mod -- then it should be something like the command above; or: you have also a dev environment through shell.nix -- then you have to define it there somehow
<booglewoogle>
i've read that nix(os) supplements haskell development really well, and i've chosen to learn haskell as a first language (apart from some rudimentary python)
<kreetx>
I'm not that far yet, so I don't know how any of these are done
<booglewoogle>
okay
<truthadjustr>
tilpner: ok.. how can i install it as a normal user? i don't want to switch my main system to unstable
<booglewoogle>
okay, i've tried to install ghc-mod (haskellPackages.ghc-mod as found in the nixos package search) via my configuration.nix now. getting "error: The option value `environment.systemPackages.[definition 40-entry 45]' in `/etc/nixos/configuration.nix' is not of type `package'."
<booglewoogle>
anyone know what that's about?
<chrisaw>
tilpner: Just found out I can workaround the issue and make home-assistant not require that package in the first plae. Happy with that workaround for now. Thanks for your help! :)
<truthadjustr>
i can't run 'nix-repl' as normal user. Error says: error: Nix database directory ‘/nix/var/nix/db’ is not writable: Permission denied
<clever>
truthadjustr: either use `NIX_REMOTE=daemon nix-repl` or `nix repl`

i have virtualbox. But the virtualisation.virtualbox.host.enableExtensionPack = true is only available in the unstable channel. How can I have this setting as normal user? I don't want to switch my main system to unstable

truthadjustr - You can replicate that behaviour manually, by overriding global virtualbox with virtualbox.override { enableExtensionPack = true; }

I'm testing this https://stackoverflow.com/questions/43375880/how-to-build-a-docker-container-with-nix to create a docker from macos, but when I run it it says 'standard_init_linux.go:190: exec user process caused "exec format error"'. I'm guessing it's an archetecture mismatch, but can't seem to be able to to build for linux (which is what docker always runs, right?)

it looks like it builds the docker on the macos, and then running that inside docker fails

anyway, it's probably a matter of it not looking in the right places. You could try to run your thing with strace to see where it's looking and what it's failing to find
<sphalerite>
something like strace -fe file -o >(grep ENOENT) your command here
<sphalerite>
There will be a lot of files that are eventually found which won't be relevant, but if you can find anything with glib-networking that could be interesting. If it's a .so path that's missing you might need to wrap your program to set LD_LIBRARY_PATH
<sphalerite>
there's also some sort of gobject-introspection stuff, maybe "typelib" files, where the search path can be controlled with some similar environment variable.
<sphalerite>
I'm not sure about the exact details though, I haven't really used lua stuff at all nor do I know that much about glib* packaging

I had a look at the files in glib-networking, found that there were "gio modules" in lib/gio/modules
<sphalerite>
the sensible thing to do from there would be to grep for lib/gio/modules in nixpkgs to look for prior path settings, and that would have got me to the solution much quicker

<sphalerite>
but I grepped for GIO_ in all the existing wrapper scripts I have instead, because that's what I (correctly) suspected the environment variable to look like
<sphalerite>
unfortunately there's no one universal method for solving this sort of issue. But usually strace is useful, as is inspecting the contents of the allegedly missing dependency.

I'm writing a NixOS test for mpd and I don't understand why the test fails when I run `nix build -f mpd.nix` yet it works fine when I run the nixos-test-driver script and execute `testScript`. The difference that I see in the log is that when the test fails it's because it doesn't run the `mpc add ...` step. The test is here: https://github.com/emmanuelrosa/nixpkgs/commit/8c55e03e744b9cd5f91b3864fe212a15b6205685 Any ideas?

Nevermind, found the problem. The service I added to create the test "music library" was starting before mpd, and thus it failed.

Can anyone help me override incompatibleKernelVersion? So far I've got the following as an overlay: zfsUnstable = super.zfsUnstable.overrideAttrs (old { incompatibleKernelVersion = null; });

Sadly no luck so far :|
<gchristensen>
chrisaw: I think you would have to edit nixpkgs locally :/
<chrisaw>
gchristensen: Really? I figured I'd be able to override that one variable but a bit mystified because the check for that variable happens outside of the actual package definition.
<gchristensen>
yes
<chrisaw>
I suppose I could fake the kernel version but that's super hacky :|
<gchristensen>
because the check happens before you're able to override the package

Hey, anyone with a hydra instance available to give me some hints about a problem I'm having? my hydra site is trying to load a bunch of scripts with http:// and I setup the nginx connection to use SSL, and have forceSSL = true set on the virtualhost. Firefox is blocking the mixed http content from loading over the https connection, so the CSS and scripts on my hydra page aren't loading. Disabling that protection in firefox lets the site load fine, but
<Lisanna>
I don't have to do this on hydra.nixos.org. What's up with that?
<chrisaw>
gchristensen: I'll pick this up tomorrow. Pretty late here. Thanks for the help! :)
<Lisanna>
gchristensen thanks, now just have to convert that to nginx equivalents
<Lisanna>
gchristensen got it, thank you!
<LnL>
Lisanna: build the config with nix and copy the relevant parts
<Lisanna>
LnL thanks, I got it working with setting those headers

Does anyone have ideas on what would be most complicated or how difficult it'd be to fork and replace systemd in nixos? Like, are there systemd-specific things that are going to make this extremely difficult?
<gchristensen>
yes
<PolarIntersect>
hmm... Any specifics?
<gchristensen>
all of nixos
<gchristensen>
you might look at SLNOS, "Suck-less NixOS"
hph^ has joined #nixos
<PolarIntersect>
But, like, does Nix depend on systemd?
<PolarIntersect>
or just NixOS?
<gchristensen>
nix does not
<PolarIntersect>
dope
<PolarIntersect>
That was my main concern :D
<PolarIntersect>
Thank you, gchristensen <3
<gchristensen>
yep!
<andi->
What is your requirement? No references to systemd on the systemd? Just another init system?
<PolarIntersect>
Is SLNOS an actual suckless.org project?
<gchristensen>
no
<PolarIntersect>
ah
<PolarIntersect>
andi-: No systemd processes running at all

or isntalled
<andi->
that should/could be feasible. The other would require a bit of patching in all the different applications that might have a reference to it (dbus,...)
<srid>
Is it possible to enable services (eg: `services.emacs`) from the `nixpkgs-unstable` channel?
<sphalerite>
PolarIntersect: unlikely to be possible while maintaining binary cache compatibility, since a whole bunch of stuff links to udev and udev is provided by systemd. but I presume that won't be much of a concern for you

I have problems with the kubernetes setup. I used 3 computer 1 master 1 node 1 client, ( I changed the kubeconf parameter for every service ) but when I deploy a service (and pods) I can't access the services but the pods. ( the services are in 10.0.0.0/24 but there is no route for that configured and the pods are in 10.1.0.0/24 there is a route for that. I did not touch any of the IP range stuff.
<PolarIntersect>
sphalerite: I mean, rebuilding the binaries is a potential solution to that.
<palo>
any advice ?
<PolarIntersect>
You deployed a client as a server, or it's just your workstation?
<sphalerite>
PolarIntersect: yep. Not sure replacing systemd with eudev for udev purposes would be accepted in nixpkgs itself though

Is there a trick to installing jekyll via nix? I tried "nix run nixpkgs.jekyll --command jekyll new my-jekyll-thing" and it failed with some missing gems.
<camsbury>
ah you manage your emacs modes via nix?
<infinisil>
Yup
<camsbury>
I currently bring my emacs packages in through an `emacs.nix`
<camsbury>
but that is pretty cool
<Lisanna>
okay wtf, I added the pinned nixpkgs as a separate jobset, no IFDs at all, and it's still complaining that it's not allowed to access the URI in restricted mode
<Lisanna>
well how on earth is it going to build anything if it can't access anything?
<infinisil>
Lisanna: it can access stuff in NIX_PATH
<Lisanna>
infinisil how is it going to have any hope of building any of the packages in my channel, since the source code for those packages exist on the net?
<Lisanna>
I can't add the sources for EVERYTHING to my NIX_PATH
<Lisanna>
that's insane
<infinisil>
Restricted mode huh..
<Lisanna>
Yes
<Lisanna>
I have a nixpkgs.nix which just does a builtins.fetchTarball on a nixpkgs nixexprs
<Lisanna>
I import the nixpkgs.nix as a jobset but the evaluation fails
<infinisil>
So your problem is that restrict-eval implied being unable to IFD?
<Lisanna>
oh wait hang on, I might be dumb
<Lisanna>
MIGHT be dumb
<infinisil>
We are all dumb sometimes ;)
<Lisanna>
oh, duh, the nix file needs to be a jobset, not the build product of fetchTarball
<Lisanna>
can I configure a recursive product reference within a jobset?
<Lisanna>
I have { nixpkgs-nixexprs; tarball; } as things in my jobset
<Lisanna>
I want to pass the nixpkgs-nixexprs product as an input to the jobset file itself
<Lisanna>
so, recursive
<infinisil>
Never used jobsets, can't help much with that

<infinisil>
"The option `system.stateVersion' defined in `/home/infinisil/cfg/config/hardware/pc' has been renamed to `system.nixos.stateVersion'."
<infinisil>
But then I change it and I get this error:
<infinisil>
"error: The unique option `system.nixos.stateVersion' is defined multiple times, in `/home/infinisil/cfg/config/hardware/pc' and `/cfg/external/nixpkgs/nixos/modules/rename.nix'."
<infinisil>
-.-
<Lisanna>
OK seriously wtf
<Lisanna>
why is it trying to access that URI at evaluation time
<Lisanna>
I'm not doing any IFDs
matthewbauer has quit [Read error: Connection reset by peer]
<Lisanna>
OK, so is there an equivalent builtin which downloads a tar.xz and unpacks it?
<Lisanna>
trying to fetch nixpkgs without depending on nixpkgs
<infinisil>
"allowed-uris: A list of URI prefixes to which access is allowed in restricted evaluation mode. For example, when set to https://github.com/NixOS, builtin functions such as fetchGit are allowed to access https://github.com/NixOS/patchelf.git.";
<Lisanna>
infinisil allowed-uris wouldn't help if the entire function is just completely disallowed
<gchristensen>
ah indeed
<Lisanna>
gchristensen yeah but then it's not declarative ):
<infinisil>
Yeah, but is the whole function disallowed?
<infinisil>
Or do the docs have a mistake there?
<infinisil>
Because the man page doesn't imply that
<Lisanna>
I want to control the version of nixpkgs from within my own nix expressions
<gchristensen>
infinisil: it is vague, because "This function is not available if restricted evaluation mode is enabled."
<infinisil>
An easy way to find out is to just test it :)
<Lisanna>
I understand the regular limitations of restricted eval mode, and am glad they exist, but blacklisting an entire builtin seems overly harsh. Why is that function so dangerous?
Fare has joined #nixos
<gchristensen>
Lisanna: it executes code as the user calling it, outside of the sandboxing of Nix
aarvar has joined #nixos
<gchristensen>
so it could trigger nasty problems in curl, git, tar, gzip, all as the user calling it without any protections
<infinisil>
Lisanna: Just test if allowed-uris works with it first
<gchristensen>
^ agreed
<Lisanna>
OK, testing

"allowed-uris https://"
<infinisil>
You gotta give it full uris
<infinisil>
It's bare string comparison iirc
xcmw has joined #nixos
<Lisanna>
ugh, yep
<infinisil>
And it wouldn't be much of a restricted mode if you could fetch arbitrary stuff tbh..

<infinisil>
Error in the manual eh
<gchristensen>
Lisanna: how did you set it?
<gchristensen>
Lisanna: it is a nix.conf setting not hydra setting
<Lisanna>
I know
<infinisil>
Yeah I don't think this http:// trick works (anymore at least)
<Lisanna>
then that error showed up in the hydra eval error log
<Lisanna>
that's still not a happy solution <_< 'cause now I have to have information about where nixpkgs comes from in two completely seprate locations. honestly I'd rather just pin it directly in hydra
<infinisil>
Make a git clone?
alexteves_ has quit [Remote host closed the connection]
<infinisil>
Then there ain't no fiddling with nix.conf and no downloads
<gchristensen>
then allow everything
<gchristensen>
the restriction and flexibility is up to you
<gchristensen>
it is a good thing for Hydra to default safe
<Lisanna>
The correct solution I'm looking for is quite simply just a fetchurl with an unpack phase, which would be allowed in restricted eval
<infinisil>
and to update a git repo is about the same effort (or even less) than updating nix.conf along with the url you use
<Lisanna>
I think, at least
<infinisil>
Oh, not sure if that's possible with your set up, nvm
<PolarIntersect>
wat
<infinisil>
I'll just shut up, I've never set up hydra
