I figured out a way to manually do it via overriding the checkPhase, but this definitely runs counter to the nixpkgs manual documented behavior of "it runs 'make check' by default"
<spinus>
but it's manual specific to buildGoPackage or just mkDerivation?
hellrazo1 has quit [(Ping timeout: 245 seconds)]
<calvertvl>
there is nothing in the manual for buildGoPackage about the checkPhase being special at all

Does anyone here use i3 with configs that don't destroy your eyes? My default terminal is blindingly white
<i3>
I'm not sure how to set up ~/.Xresources so that it works in conjunction with i3 and my main config
<pseudo-sue>
I haven't tried it on nixos yet, but have you tried fiddling with .Xdefaults?
<nixy>
i3: What terminal are you using?
<pseudo-sue>
a lazy workaround is to just use another terminal emulator instead of xterm, and get i3 to open that. roxterm is pretty painless to customize, e.g.
<c74d>
I set `*foreground: rgb:A8/A8/A8` and `*background: rgb:00/00/00` in Xresources
<c74d>
except, hm, I don't use ~/.Xresources, I have my NixOS configuration create an Xresources file in the Nix store, and set config.services.xserver.displayManager.sessionCommands to load that file
<pseudo-sue>
yeah, my xterm seems to be ignoring .Xresources and .Xdefaults too...
<i3>
Ok, so just to be clear: I open up ~/.Xresources and type what you just typed?
<i3>
c74d: any changes necassary to configuration.nix? Should it be set after a nixos-rebuild switch and reboot?
<c74d>
you could copy the foreground and background settings
<c74d>
i3: you'll need to log out and back in; I'll check whether configuration.nix changes are necessary
<i3>
do they need to go into configuration.nix or .Xresources?
<i3>
Oh ok, nvm. Thank you!!
<i3>
You're a saint
riclima has joined #nixos

I put them in configuration.nix but that's slightly more work
<c74d>
i3: you shouldn't need to change configuration.nix if you use ~/.Xresources

just log out and back in
<c74d>
(I put the settings in my configuration.nix rather than in ~/.Xresources because I try to keep as many settings as feasible in configuration.nix)

ok, so, i'm still in the world of GLX pain. there's been some user churn here, so I might as well ask again: steam is crapping out on me on startup with the error message "OpenGL GLX extension not supported by display". has anyone encountered and solved this problem before? I'm working on a thinkpad p51 with nvidia and intel graphics.
<calvertvl>

not that i'm aware of.

Hi! I am trying to use a YubiKey with NixOS. If I run gpg2 --card-status as a normal user, it fails, but if I do it as root it works.

<kojiro>
the usb device is /dev/bus/usb/001/021, and it is owned by root:root
<nix_n00b>
Anyway, I'm wondering if, in the simplest terms, users or profiles are reproducible on NixOS. As in, can I create a VM or new machine that has all my programs and configs for each one?
<kojiro>
calvertvl: scdaemon, yes
<nix_n00b>
And example would my precious vim configuration, is something like that, adn all my other configs, reproducible?
<kojiro>
calvertvl: hmm, that seemed to be a different problem. according to list.gnupg.org, the usb device should at least have a group ownership other than root...
<gchristensen>
nix_n00b: anything expressed in your configuration.nix would carry over

which I think can include your vim config, but perhaps not _all_ your user config, likefirefox settings
<calvertvl>

nix_n00b: home-manager looks more nix-y, but for unsupported packages you'd have to write additional modules... the .nixpkgs one mostly just does dependency injections into hand-written files
<nix_n00b>
I think it'd be cool if NixOS adopted home-manager so it got some real dev work, it does sound nix-y. I don't know if I run any unsupported packages as I'm a super noob. What do you mean by "dependency injections?
<nix_n00b>

<calvertvl>

<kojiro>
I'm trying to figure out which /dev node corresponds to which usb device. Can I map something in the output of dmesg to a /dev/bus/usb/** somehow?
<calvertvl>
so if you wanted to e.g. run taskwarrior on a couple of different task lists, you could use that to override
<calvertvl>
or setting up commands in xmonad instead of installing them systemwide
<calvertvl>
(or per-user)
<nix_n00b>
sounds like home-manager is more what I'm looking for then
<calvertvl>
the benefit to home-manager is that it could do this directly in addition to the more nix-friendly configuration scheme
<nix_n00b>
thanks for the english translation though :)
<calvertvl>
yeah, it looks better to me too
<nix_n00b>
Yeah I wondr how many NixOS devs know about it, I just stumbled upon in a reddit comment sometime last week
<nix_n00b>
and I couldn't stop thinking about how nice that'd really be
<nix_n00b>
I have a couple friends I'm supposed to introduce to linux and programming, and I thought that'd be such a nice way, just to be able to reproduce my system in a VM for them like magic
<kojiro>
something has to be setuid here - my mouse is root:root /dev/bus/usb/001/018 and that device works fine as non-root

maybe the problem is scdaemon itself

calvertvl:^
<nix_n00b>
they will be very simple Scheme and C things anyway
<calvertvl>
nix_n00b: for e.g. python stuff, you're better to run for example a nix-shell with a shell.nix that has the python packages added to it, as installing them directly doesn't really work
takle has joined #nixos
<nix_n00b>
that must be because the OS is still in development?
<calvertvl>
nix_n00b: for scheme and C, unless you're linking against lots of system libraries it may work fine regardless, but if you run nix-collect-garbage you may need to rebuild things
<nix_n00b>
calvertvl: Where do these problems come from? I don't understand how compiling and executing a C program, or python, or anything would cause anything like that
<calvertvl>
nix_n00b: it's because of the functional aspects of nix
<nix_n00b>
I thought these programs would be sandboxed, for lack of a better word. I guess there's a big picture I'm missing.
<calvertvl>
nix_n00b: in other words, your user environment has certain packages, but if you install/remove things, references may be changed or removed
<nix_n00b>
and how does that relate back to python and such causing trouble?
<calvertvl>
nix_n00b: best way to sandbox is to write a default.nix that pulls the dependencies in and so on
<nix_n00b>
calvertvl: default.nix?
<calvertvl>
nix_n00b: in the python case, I think it had to do with e.g. nix-env -i not updating the library path for python, whereas using buildPythonPackage in a .nix file takes care of all that for you

<nixy>
Kind of. You would have to go and edit your system packages or config.nix instead of just running `nix-env` in your shell
<nixy>
Once you figure out how python packaging works it isn't difficult, but it is unintuitive at first
<calvertvl>
kojiro: if you wind up using home-manager or the .nixpkgs one, you could probably write it as ${pcscd}/lib/... but that's probably as close as you could get
<kojiro>
ok. I'll live with it for now
<nix_n00b>
nixy: Now this, to me, sounds like something that would get smoothed out as popular packages are repackaged for NixOS, right?
hexagoxel has joined #nixos
<nix_n00b>
e.i a NixOS concious python packager could make things easy as pie?
<kojiro>
nice wording
<nixy>
nix_n00b: Python applications, such as `ranger`, will be as easy to install as anything else
<nixy>
The only issue here is with making libararies available in a python interpreter for local development or running in a REPL
<nixy>
This is really an issue with how python works and how nix works. Someone clever may come up with a solution that fixes this, but I don't think more people using Nix for python will solve this
<nix_n00b>
nixy: There must be many more identical problems with similar languages then?
<nixy>
nix_n00b: I believe you can run into similar issues with header files in C, but I don't package things for C :P
<kojiro>
heh, I'm a Pythonista and I'm not sure I see it as a problem.
<nixy>
^
<nix_n00b>
kojiro: why's that? ideally wouldn't everything install fine with nix-env?
<kojiro>
depends on your definition of "install fine"
<kojiro>
you have to know exactly what you mean by that
<nix_n00b>
and how might an experienced user like myself detect when I should not use nix-env?
<nixy>
Some would argue that you should never really use nix-env
<nix_n00b>
kojiro: works without breakage and minimal complications
<kojiro>
if you are building a python app with a dependency, package it the python way.
<nix_n00b>
nixy: Oh, interesting.. I was just copying the manuals syntax.
<nix_n00b>
nixy: what would a true NixOS gentlemen use?
<kojiro>
hah
<kojiro>
nix_n00b: consider this (and I'm quoting what I read here, I'm a nix noob) - if nix lets you install a package with a modified configuration, but that package is also a dependency of another package, how does nix ensure that the configuration change doesn't break the dependent package?
<nixy>
Some of the more seasoned people around here use `buildEnv` in config.nix or just the `environment.systemPackages` to manage things in a declarative fashion
<kojiro>
If nix particularly wanted to be crazy pythonic, it could publish "sites"
<kojiro>
but that still wouldn't get to the crux of the matter
<kojiro>
because you wouldn't know which sites to mix up
<kojiro>
language libraries are best handled by the language's package manager, in a contained environment like virtualenv
<nix_n00b>
Stupid question, but do people in other OS's have difficulty setting up a purely functional like haskell in a non-functional enviroment?
<nix_n00b>
or is this problem one way?
<nix_n00b>
"problem" for lack of a better word
<kojiro>
surely it's easier to handle purity in an impure environment than it is to handle impurity in a pure environment
<nix_n00b>
makes sense
<kojiro>
nixos is pretty unique
<kojiro>
that said, nixpkg can be installed on various os's, and it will still have this behavior wherever you put it
<kojiro>
nix_n00b: actually, that reminds me -- are you familiar with homebrew? There's an analogous problem there.
<simpson>
You can always create "pure" and "impure", as you call them, by introducing a new top-level scope.
<nix_n00b>
homebrew? No, but it sounds familiar
<kojiro>
it's a package manager built for macos - anyway, if you happen to be in a python virtualenv when you install a thing with homebrew, and that thing has python dependencies, you'll be in for a fun time
<kojiro>
the python dependencies will get put in the virtualenv, but the rest of the stuff will be installed globally
<kojiro>
so your program will "exist", but behave differently inside and outside the virtualenv

simukis has quit [(Ping timeout: 240 seconds)]
<nix_n00b>
kojiro: interesting! And this happens for a reason analogous to the Nix Python problem?
<kojiro>
maybe the word "inverse" fits better
<kojiro>
it's the /inverse/ problem
<kojiro>
nix isolates the python package from the thing some people think it should be able to depend on
<kojiro>
in homebrew, the virtualenv isolates the python package too -- meh, maybe it's not so inverse
<kojiro>
I'm tired :)
<kojiro>
nix_n00b: the point is that if you were installing some nix-packaged thing that had a python dependency, it would probably work fine
<kojiro>
you just can't install a random python library with nix-env and expect it to be available to the python path
johnsonav has joined #nixos
<nix_n00b>
kojiro: huh, interesting about homebrew. And ok, perhaps not with nix-env, but there are other ways?
<kojiro>
ways to do what? install a random python library?
<nix_n00b>
yeah I think Nixy was mentioning using something like buildEnv
<kojiro>
I'm not familiar with buildEnv
<kojiro>
I can only talk about the Python standards here
<nixy>
So if you wanted to run python3 with numpy you would just put `python3` and `python3Packages.numpy` in the paths list
<nix_n00b>
oh wow ok, I see now. I thought this was being run from the commad line like nix-env
<kojiro>
nix_n00b: so what, you do this and then you switch to that env with e.g. nix-env --switch-profile?
<nix_n00b>
well that's kinda cool, much less problematic than I was thinking
<kojiro>
nixy ^
<nixy>
The env isn't a profile, but its an installable thing
<kojiro>
installable with nix-env -i?
<nixy>
So if you have that definition in your ~/.config/nixpkgs/config.nix you can then run `nix-env -i pythonTools`
<kojiro>
huh
<kojiro>
nice
<kojiro>
so the question is, having done that, is pygments on the pythonpath for that particular profile's python?
<kojiro>
I gather so
takle has joined #nixos
<nixy>
kojiro: I am not _exactly_ sure how it works, but I am pretty sure that it explicitly points the pythonpath to those packages, since it know the packages that should be in the path to start
<nix_n00b>
So in the NixOS community is this Python (and similar) faux pas viewed as a benefit, a drawback or just some collateral side effect?
<nixy>
It's seen as an acceptable side effect for having purity and correctness
<simpson>
nix_n00b: Eventually you learn to like doing it the nixpkgs way.
<kojiro>
it is at very least a necessary behavior to get some of the other benefits of nix
<nix_n00b>
simpson: ok, thanks. kojiro: makes sense too
<nix_n00b>
I would just think there would at some point be some sort of automated way to do it

takle has quit [(Ping timeout: 245 seconds)]
<nix_n00b>
nixy: but just to be clear, after installing it the nixos way, it would work fine?
<nix_n00b>
kojiro:^ also for this pythonista :)
<Olgierd>
and using systemd-boot
<kojiro>
nix_n00b: I don't really see a conflict. You seem to be asking to bridge a gap between installing a tool for development in a specific development context (Python, in this case) and installing a package for use as a user.
<nix_n00b>
you've got a hard drive plugged into the USB and you're trying boot from that?
<nix_n00b>
Olgierd: is your boot order right?
<kojiro>
if you want to install it as a tool, don't expect it to work for development. If you want to install it for development, expect to manage it as a developer
<kojiro>

kojiro: Ok, I just want to make sure it's not going to be a hairy mess just writing simple python programs in NixOS

but given it searches for the uuid and not the device name, so it should not get stuck

speaking of python, I remember hearing here a while ago that pip isn't really well supported by nix, and that pypi2nix should be used instead. is that right? I'm just interested in providing a few libraries, globally, that I use in various utility scripts.
<pseudo-sue>
pypi2nix doesn't seem to work, at least not off the shelf -- it throws an error about not being able to find the pkg_resources module.

also, are you using pypi2nix from git? the one in nixpkgs is not so great IME

i find that the vbox gui is good for when you dont know what options you want, and want to play with things

I suppose if someone built the appropriate vagrant provider, then qemu would be better in that case

clever: I've been having trouble with virtualbox run as my user rather than sudo; it complains about not being able to find the kernel module

calvertvl: you may need to reboot, nixos-rebuild doesnt load kernel modules

I've rebooted several times with that config in place after a rebuild; starting with sudo works fine

Logged in as root I run chown root:root /home/user/file && chmod 444 /home/user/file which succeeds, but if I then open the file as the normal user with vim and save it by :write!

takle has quit [(Ping timeout: 255 seconds)]
<clever>
arianvp2: neat
<jophish>
clever: how does this sound: a store api implementation "NetStore". The store becomes the union of the stores on a bunch of networked computers. When a path is requested it's torrented (or similar) from any of the peers which have that path, using hard link information to save network
<arianvp2>
:)
<jophish>
It would be so useful for us here
<jophish>
we have many machines with nix stores on, with very similar sets of paths
<clever>
jophish: nix-serve can sort of do that already, but you would have to add every machine as a binary cache
<arianvp2>
jophish have you seen nix-ipfs?
<arianvp2>
this is very close to what you're proposing
<jophish>
arianvp2: yeah, that's very similar
<jophish>
I didn't think it was really usable at the moment
<arianvp2>
yeh idk
<jophish>
and I don't know how appropriate ipfs is for private files
<jophish>
clever: yeah, perhaps I should set that up
<arianvp2>
not that appropriate
<arianvp2>
:)
<jophish>
nix has some unpleasant behaviour when caches are not up though
<arianvp2>
You can create private ipfs clusters I think
<jophish>
arianvp2: perhaps that would do
<jophish>
clever: and a nix-serve based system might be hard to get performant all the time
<jophish>
for example: although most of our machines are in the same office (with a slow upload speed) others are in the US
<jophish>
they shouldn't stream from the office computers as often
<jophish>
torrenting/ipfs handles this nicely as far as I can see
<jophish>
I suppose minimising transfers using hard link info is an orthogonal issue
<jophish>
but it's important to us, I reclaimed >200GB the other day with --optimise :)

So the next boot will run the new build, but subsequent boots will still use the current one unless the change was persisted.

Build and activate the new configuration, but do not add it to the GRUB boot menu. Thus, if you reboot the system (or if it crashes), you will automatically revert to the default configuration

When following the Manual to get proprietary drivers installed for AMD cards (AMD E2 APU with a Radeon 6320 chip) nixos-install complains that hardware.opengl.driSupport32bit does not exist.

D´oh
<clever>
KABA: LD_PRELOAD can potentialy break some programs that your program may spawn, since it forces things to load
<tanonym>
I will do a rebuild afterwards, since the build is currently in progress.

KABA: while LD_LIBRARY_PATH just changes the search path, just be sure to prepend/append, because opengl also needs LD_LIBRARY_PATH to stay intact

gleber_: I was just having a conversation with some people in #elixir-lang about the viability of adding some sort of external-deps meta field so that it would be easier to specify external deps for Nix. But some people brought up a couple points that I did not really know how to answer. I was hoping you, or anyone else here, would be able to help out in answering.
<gleber_>
I can try to help, although I am not an expert in Elixir (I used Erlang extensively though_
<gleber_>
)
<Ankhers>
That should be good enough. I will hopefully be able to translate.
<Ankhers>
From my understanding, Nix provides pre-compiled binaries for whatever can be compiled. Does this include things in beamPackages? Or do those only get compiled when run?
<gleber_>
Nix provides a reproducible script to build all packages it contains. There's a cache which contains these packages in pre-compiled form (e.g. including binaries)
<Ankhers>
Ok. Elixir allows you to have compile time dependencies and configuration. It wouldn't really make sense to share compiled versions of a lot of packages. What would that look like within Nix?
<Ankhers>
I'm not really sure if that question makes sense.
<gleber_>
These compile time dependencies would be encoded in appropriate Nix derivation definition in Nixpkgs. Each configuration (I assume this is the same as Rebar profiles) can be a different derivation.
<gleber_>
And you could say that a derivation is a complete reproducible script to build a package (including all of its deps)
<gleber_>
You should not care about the compiled versions at all. You should care which derivations to include in Nixpkgs, i.e. how many versions of each package to include, how many compile configurations to support, etc.
<gleber_>
For example beamPackages.nix contains each most recent version of each package in Hex (unless any of these depends on older version of a package, then hex2nix would define two versions of a package).
chrishill has joined #nixos
<Ankhers>
I'm going to use a package called ecto as an example. It is a database wrapper that supports multiple databases. You specify in a config file which database you want to use it with. Then, when it compiles, it looks to see which databases you are wanting to support and only emits the beam files for those databases. Does this make sense within Nix?
<chrishill>
Hi. I am having problems installing a `base` Haskell package: `nix-env -f "<nixpkgs>" -iA haskellPackages.base_4_9_1_0`.
<gleber_>
Oh! Does it perform database queries at build/compile time?..
<chrishill>
This fails to build.
nix_n00b has quit [(Quit: Page closed)]
<Ankhers>
Not actual queries, no.
<Ankhers>
It just decides what things to actually compile based on what is loaded in the system.
<gleber_>
What does it mean "what is loaded in the system"? Which system is that? What kind of things can be loaded in there?
<Ankhers>
a beam node. The elixir compiler is built in erlang.
<gleber_>
ok, Nix does use BEAM when building, so you can define a hermetic and reproducible way to reconstruct the state of the VM, you can make it work in Nix
<Ankhers>
Ecto provides support for I think 3 databases inside of it. Lets say that the Postgrex (postgres) module is loaded, it will not try to build the mysql specific modules within ecto.
<Ankhers>
Alright. I think there will still be a benefit to using Nix then. I guess I just need to learn more about Nix and how it works.
<KABA>
chrishill: Is it a custom package you've written?
<Ankhers>
I need to get my NixOS VM setup so that I can play around with this stuff.
<gleber_>
Ankhers: yes, that's my feeling as well
<gleber_>
Ankhers: you do not NixOs to make use of Nix and Nixpkgs
<gleber_>
I did all my development of Erlang stuff for Nixpkgs on Ubuntu
<gleber_>
(Although I did test it few times on my remote NixOs machine)
<Ankhers>
I know. I just feel if I do not force myself to use it, I will never properly understand it.

Unfortunately my Erlang is spotty at best. But things should be similar to Elixir, I believe they share semantics for the most part. If you want any help with hex2nix, or anything else. Just ping me and I will do what I can.
<gleber_>
Ankhers: if the mechanism you meant is what is described in https://github.com/elixir-ecto/ecto#usage as "You need to add both Ecto and the database adapter as a dependency to your mix.exs file", then this is totally doable in Nix
<gleber_>

I'm having a bit of trouble getting my wireless interface working in a new nixos install. ifconfig reports the interface to be up, and shows its mac address, but it seems to be otherwise unresponsive.

<chrishill>

<Sonarpulse>
shlevy: hmm that's an interesting question
<Sonarpulse>
I can add a bit
<jophish>
That's the plan for hercules
<jophish>
but just a plan :)(
<Sonarpulse>
if there is to be a seperate initial evaluation step
<shlevy>
jophish: Hercules has a plan already based on RFC 14? :o
<Sonarpulse>
then yes
<Sonarpulse>
shlevy: the underlying issue #666
<Sonarpulse>
shlevy: one thing I can certainly say
<Sonarpulse>
evaluation errors should be handled per evaluation
<Sonarpulse>
even now that would be an improvement
<shlevy>
:D
<Sonarpulse>
but with this because evaluation errrors can accumulate, all the more so
<shlevy>
You mean just seeing the latest eval errors isn't useful to you?
<jophish>
shlevy: no code though
<jophish>
Actually, I started on this with my libstore implementation
<shlevy>
Honestly for the nixpkgs eval the evaluation errors tracking we have is useless
<jophish>
hercules will not have any distinction between evaluation and building
<Sonarpulse>
for cross-trunk
<Sonarpulse>
they are better
<Sonarpulse>
+1 hercules embracing a conflation
<shlevy>
I should open an RFC for extensible/accessible context
<Sonarpulse>
I think it's good in *Nix* there is still clean layering
<Sonarpulse>
as I explain in my rfc
<shlevy>
And backpack derivation poisoining on top of that
<shlevy>
jophish: Why not?
<Sonarpulse>
but for hydra/hercules/anything on top, I don
<Sonarpulse>
't think it
<Sonarpulse>
's so important
<jophish>
shlevy: well, import from derivation muddies it so much already
<shlevy>
Not really
<shlevy>
it *can*, in principle
<jophish>
with the libstore stuff hercules will request a build, and just queue up any requested paths until its done. I think it's conceptually simpler
<shlevy>
But in practice the stuff that happens at eval time is very different in kind than what happens at build time
<shlevy>
jophish: That's too abstract for me to understand how it's different than hydra :D
<Sonarpulse>
shlevy: anyways to answer your question in the rfc
<Sonarpulse>
I really want rapid release
<Sonarpulse>
hacking on Nix without that will be very annoying
<Sonarpulse>
:)
<shlevy>
Sonarpulse: Yes, agreed
<jophish>
shlevy: I'm not sure that's the case for the stuff we have going on here, for example the cabal2nix tool is required for eval, and that can spawn a whole host of haskell package builds
<shlevy>
Sonarpulse: It's getting in the way of my motivation to hack on readonly recursive nix
<shlevy>
jophish: Sure, once in a while. And you can (and, IMO, should) structure your projects such that that once in a while is *very* infrequent by pegging a different nixpkgs set for eval time deps
<Sonarpulse>
shlevy: I do think in practice
<shlevy>
jophish: So hercules won't be able to queue up a new set of builds until the previous one is all finished?
<Sonarpulse>
there will be few layers deep of importing from derivations
<jophish>
shlevy: so my libstore implementation intercepts calls to "buildPath" and forward them to a socket (which the hercules server is listening on). 'buildPaths" gets called the same regardless of whether we are in nix-instantiate or nix-store --realise
dbmikus has joined #nixos
<Sonarpulse>
and the initial layers, like cabal2nix are super cheap
<jophish>
shlevy: we do peg like that, don't worry :P
<shlevy>
Sonarpulse: Hmm, can you give near term examples of deep layers?
<civodul>
Sonarpulse: to determine whether a graft is applicable to a given package, you first need to have that package built, hence the similarity
<jophish>
shlevy: I don't think there'll be any queuing required
<Sonarpulse>
shlevy: sorry my grammar is vague
<Sonarpulse>
I *don't* anticipiate deep dynamism
<Sonarpulse>
just shallow
<shlevy>
Sonarpulse: Ah, yes, OK :)
<Sonarpulse>
such that arriving at static plan
<shlevy>
Sonarpulse: On the same page there
<Sonarpulse>
cool
<shlevy>
Sonarpulse: FWIW, I definitely don't want my arguments in favor of recursive nix to be at all construed as arguments *against* import-from-derivation
<Sonarpulse>
civodul: neat. I should learn what a "graft" is first I suppose
<kojiro>
What options does nix-shell run the shell with? It seems to source my .bashrc, but disables completions and complains that 'bash: set: vi: invalid option name'
<shlevy>
The things I ultimately want recursive nix for are pretty far-out and we definitely don't need it for a lot of what we currently want to do
<Sonarpulse>
shlevy: I would be happy to change the wording there to not misconstrue your position
<Sonarpulse>
but those points *did* help me clarify my motivation better :)
<shlevy>
:)
<shlevy>
No, the wording is good
<shlevy>
Just want to clarify
<Sonarpulse>
sounds good :)
<kojiro>
default.nix contains 'with import <nixpkgs> {}; stdenv.mkDerivation { name = "test"; }' # Simplest possible
<kojiro>
when I run nix-shell I get 'bash: vi: invalid option name' and other junk from my .bashrc, and then a prompt that looks very broken.

<jophish>
shlevy: I think it's possible to keep things running
<jophish>
I'm imagining just a big DAG which is constantly added to when new builds/evals are performed and removed from when builds are completed
<jophish>
the hercules "evaluator" adds builds, and the "builder" completes them as fast as possible
<shlevy>
OK, then I'm not sure how they're not separated :D
<Sonarpulse>
shlevy jophish:
<Sonarpulse>
one problem with my plan
<jophish>
the builds that the evaluator adds could be ones required for IFD, the results of which it'd have to wait on
<Sonarpulse>
that my last follow-up alludes to
<Sonarpulse>
is that one does not get a conventional dry-run
<Sonarpulse>
until all imported derivations are built
<Sonarpulse>
one can easily discover derivations
<Sonarpulse>
but one has no way of knowing if they are actually needed
<jophish>

so then between my --dry-run issue and that my RFC is wholely redundant :D

shlevy: importantly the evaluator would continue evaluating and adding other builds for other expressions while it's waiting for something in the dag to be built to proceed with that expression
<Sonarpulse>
jophish: it would have to be eager nix
<Sonarpulse>
this is speculative needing
<Sonarpulse>
since we can't actually finishing evaluation until the intermediate builds finish and we are un-stuck

Hm, something went wrong with the networking now. Enlightenment does not enable connman, and something is screwy when I try to get wpa_supplicant to enable. I´ve added ctrl_interface = DIR = /run/wpa_supplicant GROUP = wheel to /etc/wpa_supplicant.conf

Okay, wpa_supplicant is not functioning as expected any more. Service fails with a 255 exit cod

I thought I had that fixed.

So much for that.

Maybe I need to have the GROUP in wpa_supplicant.conf as root?
<tanonym>
Huh, says the issue is Line 2 of wpa_supplicant.conf: unknown global field Group=root and then Invalid configuration line GROUP=root
<tanonym>
So, that is where the issue is.

I'm having trouble compiling a basic C program. With GCC my error was: "gcc: error trying to exec 'as': execvp: No such file or directory", and with clang it's: "fatal error: 'stdio.h' file not found"
<nix_n00b>
I've read that imperative installations may cause some trouble, but I'm afraid I don't quite understand it or how to fix/approach this problem. If anyone could help I'd really appreciate it
<calvertvl>
anyone have any idea why setting virtualisation.virtualbox.host.enable=true somehow doesn't apply the udev rules?
<calvertvl>
(yes, this is even after a reboot)
<calvertvl>
nix_n00b: from what I saw when looking at this yesterday, it is because the dev parts of packages (headers and such) are not installed under nix
<calvertvl>
nix_n00b: so you have to use either nix-shell or a buildEnv / nix expression to build it
<calvertvl>
(when I say not installed, I mean not available in the user's environment - they exist in the nix store)
<nix_n00b>
calvertvl: In hindsight I should've installed these things during the talk yesterday. Ok, I will look at what those mean. I'm unfamiliar with the vast majority of this, but does buildEnv happen in the configuration.nix?
<calvertvl>
it seems to be user-specific, in your config.nix, but I'd have to google for links
<nix_n00b>
calvertvl: where can I read about these? cntrl+f buildEnv didn't pull up anything in both Nix Manual and NixOS manual
