Hmm, I see. But I guess a lot more needs to be done than just recompiling the nix executable, right?
<kkini>
Actually maybe I should ask another question first. Is the nix store resistant to deleting store paths? Will nix automatically rebuild stuff if it goes missing, or will it panic?
<kkini>
I suppose my questions could be answered by experimentation, lol

it's subtle, but the second declaration of mkVal gets rid of the space before the opening curly bracket, but when it calls itself the space is still there

They have Guile-based builders instead of shell-based, so if you want to install GuixSD and then use some exotic package from NixPkgs, you will have to ave two glibc copies, and maybe two copies of GTK.

Which is normal with all NixPkgs stuff…
<yegortimoshenko>
modules under nixpkgs/nixos/modules/profiles can be used by including their path to imports list. at the same time, there are modules with single mkEnableOption option, such as programs.unity3d.enable
<yegortimoshenko>
how to choose between the two?
zzamboni has joined #nixos
<gchristensen>
profiles are special modules
<yegortimoshenko>
i.e. why modules under nixpkgs/nixos/modules/profiles don't have respective enable options and aren't just wrapped in mkIf
<gchristensen>
I don't know, but unless you're making a new profile you should use the enable method
<yegortimoshenko>
sure. i'm organizing my overlay and i have a lot of modules that are akin to profiles, mostly related to hardware configuration
<yegortimoshenko>
i've used the enable method with them, and it's too much boilerplate, so i will probably use the same approach as nixos/modules/profiles
jb55 has joined #nixos
<gchristensen>
ok, I think overlays don't get automatically included in to the nixos module system anyway
<yegortimoshenko>
it's not just nixpkgs.overlays overlay, it specifies custom options as well

it's somewhat like vuizvui

Nope, it returns a derivation, but if you put it into a string, it expands to the path of the derivations result

How do I put it into a string?
<infinisil>

numerobis has joined #nixos
<iqubic>
programs.zsh.ohMyZsh.custom wants a string. That makes it harder to feed it a thing from github
<jtojnar>
what is the significance of listing a derivation in build inputs compared to mentioning it in some other key, interpolated into a string (e.g. `preFixup = "XXX_PATH=${fooPkg}"`)
<sphalerite>
jtojnar: stdenv handles it in various special ways
<sphalerite>
Like adding its bin directory to PATH, adding include to NIX_CFLAGS or something like that, etc
<jtojnar>
I am most worried about GC
<sphalerite>
The .drv will still have a reference
<jtojnar>
so what makes nativeBuildInputs special?
<sphalerite>
As for the build result, that depends entirely on whether the build result has a reference
<iqubic>
How do I find the hash to give fetchFromGithub?
<sphalerite>
jtojnar: The fact that nativeBuildInputs are always chosen from the build system's package set while buildInputs will be for the target system
<jtojnar>
iqubic: there is nix-prefetch-scripts

I've written a tool that makes it easier, really need to publish it
<iqubic>
What length should a sha256 hash be?

<sphalerite>
(And resolve the ref to something that won't change over time)

No, it uses nix-prefetch-url
<sphalerite>
MichaelRaskin: yeah but that doesn't help for fetchFromGitHub
<sphalerite>
Or rather, it's fiddly
<MichaelRaskin>
Yes, not directly
<MichaelRaskin>
It was more that you don't need your tool to cover the cases already covered
<sphalerite>
Yeah
<MichaelRaskin>
The exact scope of fiddliness is better highlighted by the fact that fetchFromGitHub can go the archive way or the git way (depending on fetchSubmodules)
<sphalerite>
But I also want a wrapper for nix-prefetch-url that I can throe a URL at and just get back the nix expression
<sphalerite>
Yes, it's rather lazy of me
<sphalerite>
:p
<sphalerite>
nix-prefetch-url --unpack https://github.com/NixOS/nixpkgs/archive/master.tar.gz + actually resolve master to a commit hash (or use a tag) + rewrite the whole thing into a nix expression myself... So much effort :p
numerobis has quit [(Remote host closed the connection)]

I sometimes use my update-walker as such wrapper.
<sphalerite>
Update-walker?

One of the horrible mess of semiautomated update tools
<jtojnar>
sphalerite: so is it alright to just use `preFixup = "gappsWrapperArgs+=(--prefix XDG_DATA_DIRS : \"${gdk_pixbuf}/share\")"`
<jtojnar>
and not add the thumbnailer to buildInputs

that is called Trust On First Use, and is a fairly valid security policy
<MichaelRaskin>
It does make some sense, in terms of making sure the contents is the same as the first time
<iqubic>
Nerdfonts are not working for me.
<MichaelRaskin>
Especially given that here «Trust on first use» is with a global repository of expected hashes.
<sphalerite>
And in addition to the TOFU thing, if it's going into nixpkgs it'll be validated by others
<sphalerite>
Yeah
<sphalerite>
iqubic: how are you trying to use them?
<MichaelRaskin>
Of course, if you fetch from GitHub by revision id, and you fetch NixPkgs from GitHub, there is less protection…

This works for me: NIX_PATH=nixpkgs=https://nixos.org/channels/nixos-17.09/nixexprs.tar.xz nix-instantiate --eval '<nixpkgs>' -A lib.nixpkgsVersion
<bobvanderlinden>
What I'm basically trying to do with the NIX_PATH is making sure nixops isn't relying on the nix-channels that I have defined on my laptop. My laptop can switch to whichever versions I'd like, but I don't want my servers to switch as well
<sphalerite>
Makes sense
<bobvanderlinden>
basically making the system configuration reproducable

I first thought this was already being done by nixops, but I just realized I upgraded my servers to nixpkgsUnstable... which was NOT my intention
iqubic_ has joined #nixos
<bobvanderlinden>
infinisil: yes
<infinisil>
If so, you can add nixpkgs as a submodule to fix the hash used for that build, then use nixpkgs=submodule/path for NIX_PATH

test
<neonfuz>
holy shit
<iqubic_>
Well, the "nix-rebuild test" failed in a strange way.
<infinisil>
neonfuz: Why are you typing commands in irc
<neonfuz>
oops, sorry idk if you guys care about profanity
<iqubic_>
infinisil: I have an issue.
<infinisil>
iqubic_: i think you mean nixos-rebuild
<neonfuz>
you know how I wrote ping google.com?
<iqubic_>
I do.
<neonfuz>
that was in a different terminal
<neonfuz>
and for some reason it's sending my messages here too...
<neonfuz>
how the hell
<bobvanderlinden>
infinisil: hmm that's one way to solve it indeed. I'll go with that for now. It seems there needs to be a better solution for nixops though
<iqubic_>
this is my issue: /nix/store/6sr4wljanv53jkx3ydj36agib9xfj2qj-oh-my-zsh-2017-03-30/share/oh-my-zsh/oh-my-zsh.sh:source:110: no such file or directory: /nix/store/6sr4wljanv53jkx3ydj36agib9xfj2qj-oh-my-zsh-2017-03-30/share/oh-my-zsh/themes/powerlevel9k/powerlevel9k.zsh-theme
<iqubic_>
Looks like my fetchFromGithub failed.

sphalerite: Previously I used an irssi config where I had "Infinisil" as my nick, but i just switched to weechat with SASL and had to enter the nick again, and now I chose "infinisil" (and prefer that) :P
<sphalerite>
Aye uppercase sucks. So much extra effort to type
<iqubic>
I am running nixos on a laptop. I have installed acpitools and started the acpi daemon via services.apcid.enable = true; however, I still can't use the acpi command to check battery status.
<iqubic>
Why the heck is that?
<sphalerite>
How can you not use it?
<infinisil>
what's the error
<infinisil>
and the package is just called "acpi", not "acpitools"
<iqubic>
sphalerite: How do I get the unstable version of noto-emoji?
<sphalerite>
Do you have any other packages from unstable already?
<iqubic>
No.
<iqubic>
Will that be an issue?
<sphalerite>
There are various ways of mixing versions
<sphalerite>
No, it's just a bit of extra setup
<iqubic>
Oh, that's a pain.
<infinisil>
it's not bad
<sphalerite>
You could add a channel for it, or you could include the unstable channel in your conffig which makes it less stateful
<iqubic>
Well, I have to go. I'll ask about this later. Sorry about that.
<iqubic>
I'll do this when I get home.
<sphalerite>
I should sleep also
<iqubic>
It'll be 3-4 hours until I'm back and able to work on mixing stable and unstable stuff
iqubic has quit [(Ping timeout: 260 seconds)]

and now I'm getting cannot connect to daemon at ‘/nix/var/nix/daemon-socket/socket’: Connection refused

any ideas?

<jtojnar>
I would like to apply for the org membership some day so I could sort the GNOME issues myself, but at the moment I do not feel confident enough about my Nix knowledge
<infinisil>
neonfuz: yes :P
<neonfuz>
nothnig really
<neonfuz>
wait yes I did
<neonfuz>
I'm dumb
<neonfuz>
I rsync'd my nix dir to my home partition, then bind mounted it over /nix
<neonfuz>
because my root partition is full and I need to do an upgrade
<neonfuz>
I should probably switch to LVM at some point lol
<infinisil>
jtojnar: Usually not many people are active at this hour
<neonfuz>
it's how I've done partitioning since I got this laptop, and I overwrote my last os with nixos
<infinisil>
gchristensen to the rescue
<neonfuz>
so it's sort of messy
erictapen has quit [(Ping timeout: 248 seconds)]
<gchristensen>
jtojnar: please please do help :)
<neonfuz>
but I thought 20gb would be enough for nixos, I guess not
<neonfuz>
I think the problem is needing space for multiple version of things
<gchristensen>
jtojnar: if you need help getting PRs merged or help making a change, let me know
<jtojnar>
gchristensen: I do have some PRs pending
<gchristensen>
jtojnar: can you link me to PRs you think are ready to merge?
<neonfuz>
I think the problem is when it updates a bunch of packages is it needs to get and install fully the new version before deleting the old one, so I need 2x the space of all my potentially upgraded packages
<neonfuz>
so... shouldn't bind mounting my nix partition work? what did I mess up?
<tilpner>
neonfuz - How did you rsync? Paste the permissions?
<tilpner>
(Although default rsync really shouldn't mess up things that much)

neonfuz - If you just want to do the upgrade, trim the new generation, "sudo nix-collect-garbage -d", and delete unnecessary files from "ncdu -x /"
<jtojnar>
gchristensen: hmm, unstable is too old, should I go with master?
<tilpner>
(But repartitioning to something bigger wouldn't be a bad idea, longterm)
