<talqu> elvishjerricco, https://pastebin.com/G3cmyL5j, what am i doing wrong here? Once in nix shell -> ghci I can't import the Turtle module
tdeo has joined #nixos
<clever> talqu: was that in a shell.nix? how did you run nix-shell?
<elvishjerricco> talqu: The `packages` argument is the list of packages you want to work on, not the ones you need to be available.
<elvishjerricco> talqu: So you're saying "Give me all of turtle's deps so that I can build my local copy of it" but obviously that's not what you want :)
<elvishjerricco> talqu: Do you want to add turtle to your cabal file's build-depends?
o1lo01ol1o has joined #nixos
<mek42_laptop> hmmm... the zfs install procedure looks too easy
<talqu> no, in that case i know i had to add it to default.nix (generated with cabal2nix). I want to add to shell.nix as a development only needed package
<talqu> just for learning purpose
<clever> talqu: is your project on github?
<talqu> clever, :), no im just poking around with these ideas now
<elvishjerricco> talqu: Alright, then that's not really something shellFor supports at the moment. Sounds like a good idea though, so I may add such a feature in the future. Anyway, for now you can add turtle as a buildDepends of your package using `haskell.lib.addBuildDepend(s)`
<clever> talqu: if you already have a default.nix from cabal2nix, you dont need to mess with shellFor at all
<clever> talqu: just make this shell.nix: (import ./.).env
<clever> or maybe: (import ./. {}).env
<clever> depending on what your default.nix wants
<elvishjerricco> clever: They also need to add ghcid as a native build input and change to a GHC with hoogle. shellFor is the lowest friction way to do that
<clever> then (import ./. {}).env.overrideDerivation
<elvishjerricco> clever: That won't let you use hoogle
<clever> ah, hoogle, that complicates things, yeah
<talqu> :)

<drakonis> i'm not sure if anyone's using the podman package right now
<worldofpeace> adamantium I don't know what to think when you say "there's no gesttings". Do you mean that the gsettings commands you try to execute have no effect or don't persist?
<adamantium> worldofpeace, the url i linked is pretty informative, but with mate, you still need to install glib to get "gsettings" on the path. And I've found it now seems to be mostly working, not every mate key mentioned by the arch wiki seems to be here, and not sure why
<adamantium> worldofpeace, for example, this one worked gsettings set org.mate.background show-desktop-icons false
<adamantium> okay wait, no i think it all works now! Well, maybe i can help the next guy then. Perhaps glib should be included with mate.nix though
<worldofpeace> adamantium Yes, I've looked at the module and there's some things that look like they were missed.
<adamantium> worldofpeace, ah, thanks. well so far i have added glib to system packages and done services.xserver.desktopManager.gnome3.extraGSettingsOverrides = true; and things seem to be working

<adamantium> worldofpeace, i wonder if we should include gnome-logs, it is what i installed and it works great. saw a bug upstream reported about it, seems the devs dont want to fix it
<worldofpeace> adamantium Does it want access to set system settings with systemd?

<bgamari> I'm just a bit surprised that even referring to drvPath causes a build
<bgamari> afterall, drvPath is just a source derivation
<bgamari> ottidmes, indeed that does the trick, thanks!

<adamantium> okay
<adamantium> i was just glancing at the gnome3 dbus services, which ones do you recommend i enable, if you have time
<worldofpeace> I'm not really familar with mate, so I don't know exactly what they're using. Though you can quickly find out if I needed service isn't running by a certain application not functioning they way you expect, and then running it from a terminal like `G_MESSAGES_DEBUG=all executable` to get some debug output.

<ddellacosta> gotcha
<gillmanash> Why does `nix why-depnds` start building the closure?
<clever> gillmanash: it operates on the runtine closure, which is only known after the build is finished
<clever> gillmanash: you can also give it storepaths to finished builds
<yl> clever: I don't want to fully use modules for the project that I have (overkill) so I have a something like `{ a = [ 1 ]; } // (import path/to/expr.nix)` where the expr.nix defines `{ a = [ 2 ]; }` and it's obviously setting it to `{ a = [ 2 ]; }`
<yl> clever: how to make it merge a instead of overriding it since it's an array?
<clever> yl: both // and recursiveUpdate will overwrite the list, not merge it, so you would need to either use a custom recursive function, or the module framework
<gillmanash> clever: Ah right, I was trying to use it so I can eliminate a failing-to-build dependency
<clever> gillmanash: nix already tells you the dependency chain, when it prints everything that failed to build, in the order they depend on eachother

<yl> clever: thank you!
<clever> yl: nixos is just repeating that pattern, across 100's of files, until you have a full distro
<clever> yl: you can also set a default value inside the mkOption block, which will vanish if the config is set anywhere
<clever> and imports is recursive, so any module can define more modules to load
<yl> clever: yea I've used the modules, but indirectly
<yl> I did not know about the evalModules and I was mostly relying on nixos-rebuild
<clever> yl: oh, and now that it is using the module framework, you could do: a = lib.mkMerge [ [1] [2] ]; i think
<yl> now I know how it works
<clever> yl: behind the scenes, nixos-rebuild is just calling https://github.com/NixOS/nixpkgs/blob/master/nixos/lib/eval-config.nix#L52-L58

<teto> clever: good idea, it gives some insight. I have been trying to run "git fetch --tags ${url}" as a postFetch operation to satisfy a program constraints but I never am in the correct folder. Will try later
<clever> teto: the body of the fetch command usually outputs directly to $out

<clever> teto: your overlay does a `exit 1` so the build fails
<clever> teto: but otherwise, it appears to be working normally
<teto> hum.. right, I was expecting git fetch to output something but I removed the url (I need to specify one since there is no FETCH_HEAD), when putting it back it fetches the tag

<omnipotententity> also a more general question, which way is preferred for installing packages, I see at least three ways: the first is to edit the /etc/nixos/configuration.nix file and place the packages in either the system environment or the user's environment. The second is to install it via nix-env. The third is to add it to your ~/.nixpkgs/config.nix file. Which way ought I be using? Or does each have particular use cases?

<clever> sure
<bemeurer> Oh, nice! I will take a look :)
<bemeurer> clever: So I am a Gentoo user. Have been for a while. I have been blessed with having access to a buildfarm which means I don't mind the compilation times, and I like compiling things myself, specially because of USE flags
<clever> the nix file deals with fetching a linux kernel, compiling the haskel code (with musl, as a fully static binary), and then buildint an initrd with that code as /init
<bemeurer> People at work love NixOS and have been pressuring me to try it, so I want to give it a shot
<clever> i was a gentoo user, prior to discovering nixos
<bemeurer> Can I get NixOS install where everything is built from source? Can I set my CFLAGS/CXXFLAGS?

<bemeurer> Interesting
<bemeurer> I tried to find docs or a blog post about it, but found nothing
<clever> i dont think its really documented, but it should be possible
<bemeurer> If there was something like that I'd make the switch this weekend
<clever> why do you want to change your CFLAGS?
<bemeurer> clever: OCD
<bemeurer> I get a weird pleasure from compiling packages
<adamt> Imagine all the CPU cycles you're freeing up by not fiddling with your CFLAGS :P
<bemeurer> Can't explain it

<bemeurer> clever: That sounds like what I want! Is it easy to do?
<clever> bemeurer: just set nix.binaryCachePublicKeys = lib.mkForce []; in your configuration.nix

<bemeurer> clever: That seems hackish, is it just invalidating the server keys, so now it can't "see" any valid binary cache servers?

<emily> how should I set the noop IO scheduler for a block device? `elevator=noop` in the command line no longer works (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914758#10), as far as I can tell the options are just a /sys twiddle and I don't know the best NixOS-y way to toggle it on boot. Write custom udev rule? just add something to the stage1?

<immae> Hey there, is there a helper function in nix that takes a script file and a list of "dependencies" and builds a wrapper around it (and modifies the `#!/usr/bin/env bash` line in it)? I can write a derivation, but it seems (?) like a rather common situation, so maybe...
orivej has quit [Ping timeout: 244 seconds]
<johanot> immae: "patchShebangs" can be used to modify the shebang line in your script. As for the "dependencies", perhaps consider "makeWrapper" with --prefix PATH ? Depending on what you're trying to do.
EoF_ has quit [Quit: eof_]
<immae> johanot: yes a makeWrapper is fine but it "forces" me to write a derivation, I wondered if there were a small helper existing already :)
<teto> immae: you can use nix-shell in the shebang ?
<teto> and pass dependencies along the command
<immae> (maybe I spent more time looking for it than write the derivation myself though)
<immae> hmm I’m not sure I follow you teto

<freeluv60spropag> Hey guys, this is unrelated to nixos but I was wondering if anyone could recommend me a dns service that is trustworthy or used by free software people
<gchristensen> for your nixos computer?
<freeluv60spropag> I don't need web hosting just the dns record thing
<__monty__> immae: I think teto meant replacing the shebang with a nix-shell shebang, it's in the manual.
<immae> ah right
zupo has joined #nixos
<gchristensen> freeluv60spropag: are you looking for a DNS resolver like / or a nameserver for your domain?
<__monty__> immae: Also note that shebangs only allow for one command and one argument afaik. Anything else isn't guaranteed to work.

mariel__ has joined #nixos
<gchristensen> I'm a big fan of luadns.com
<immae> __monty__: yes, it was a simple /usr/bin/env bash here, and I wrote the derivation by hand (with runCommand) finally :)
<clever> gchristensen: is the nameserver written in lua?
<freeluv60spropag> clever: thanks! already something promising has showed up!
<gchristensen> I doubt it, clever :)
<freeluv60spropag> looks very useful for right now but I don't mind paying for dns if it's good people
<__monty__> immae: Yeah, just mentioning it in case you wanted to do #! /usr/bin/env VAR=val bash or something.
<teto> immae: the nix-shell in shebang has quite a few quirks. What always work though is to pass a *.nix file to it
<gchristensen> clever: you express your records in Lua in a git repo, and it realises them as DNS records
<teto> no nixos.dev yet :D ?
ThatDocsLady_ has quit [Remote host closed the connection]
<freeluv60spropag> ooh luadns is also great
<freeluv60spropag> thanks guys!
<clever> gchristensen: ah, nice idea
<gchristensen> yeah
<clever> dns.he.net has a very simple http api to set a subdomain to point to whatever IP made the http call
<gchristensen> abstractions and variables are nice :P
<clever> so you can just blindly curl it in a dhcpcd hook
<clever> luagit sounds good if you want to programatically generate things, but when you have a dynamic ip, that could be a problem
<gchristensen> it is not compatible with dynamic IPs
<clever> you would need to push a new git commit every time your IP changes
<gchristensen> right
<freeluv60spropag> hmm well right now I'm just setting up my email and then I'll probably serve a webpage from a nixos box in closet at home with a static ip so I'm not too bothered

<gchristensen> sure, noonien
<vaibhavsagar> if your backend devs develop using Nix, you're already halfway there
<noonien> awesome! is there a guide i can follow?
<Taneb> noonien: we have a lot of Ubuntu machines doing builds here
<vaibhavsagar> noonien: different arch is tricky
<gchristensen> noonien: https://nixos.org/nixos/options.html#nix.buildmach
<Church-> vaibhavsagar: Well they don't develop with it.
<Church-> Although our build process is... a thing.
<vaibhavsagar> so then what are they using it for?
<Taneb> (oh, I misread arch as OS)
<dmj`> Doesn't hydra have the ability to deploy after a build has passed?
<dmj`> er, to execute an arbitrary command
<Church-> vaibhavsagar: I said they knew it
<Taneb> dmj`: there's the "RunCommand" plugin
<Church-> I didn't say they used it
<noonien> so, i can, for example, build derivations on an x86 mahine for an arm machine?

<vaibhavsagar> noonien: with emulation, yes
<vaibhavsagar> actually, oops
<vaibhavsagar> cross-compilation is also a thing
<Church-> How well does Nixops work with Linode?
<samrose> however, if I leave that out, and add it in later, the machine will autoupgrade from my custom channel/hydra and install that without issue
<dmj`> Taneb: fantastic
<vaibhavsagar> Church-: same as any other VPS with SSH access
<samrose> (it will install mozilla rust overlay without issue on autoupgrade from my channels I mean)
<ldlework> vaibhavsagar: wellllll
<dmj`> Taneb: I am using the github plugin, I wouldnt' want to execute the RunCommand script until a successful build has occurred
<dmj`> Taneb: er, until the branch has been merged
<ldlework> nixops support for various iaas is not even
<dmj`> Taneb: is that supported?
<noonien> has anyone setup lauching AWS or GCE instances just to build nix-packages?
<hyperfekt> tilpner: I'm currently implementing the scheme you told me about. Does evalModules { check = false } mean that I can have config values without corresponding option declarations?
<vaibhavsagar> ldlework: I meant that there is baseline support for any VPS with SSH access, and one can interact with a Linode VPS the same way :)
<Taneb> dmj`: I don't think so
<hyperfekt> tilpner: Disregard that question, sorry. Missed the redirected comment that explains it.

<gchristensen> benwaffle[m]: why is that patch needed?
<hyperfekt> benwaffle[m]: Strange. If you're truly building from nixpkgs-unstable that shouldn't be necessary - the channel advances only when the packages have been built.

<benwaffle[m]> I want to use curl with tls 1.3, but it says openssl is not compiled with tls 1.3 support
<liminal18> hey how i enable steam controller support?
<gchristensen> overriding openssl will certainly cause a *lot* of rebuilds.
<scientist> hey guys, I was wondering if you know where I can find a list of all the xkb keycodes, I need to add some to my configuration, thanks !
<gchristensen> benwaffle[m]: you're probably so low in the bootstrapping process that you're having to compile an interim version of libc++
<benwaffle[m]> low? bootstrapping? why doesn't it just download it?
<scientist> ?
<gchristensen> download what?
<hyperfekt> gchristensen: Well, if ben is only building openssl it should hardly build any of its dependencies?
<gchristensen> as part of bootstrapping we rebuild a some libraries a few times, each with more dependencies
<simpson> scientist: Use the `xev` tool, included as `xorg.xev` IIRC in nixpkgs, to find them for your particular hardware.
<simpson> > xorg.xev
<{^_^}> "<derivation /nix/store/12av8sz2j24yvah7n44fdbjf0jbfsb0k-xev-1.2.2.drv>"

<scientist> simpson: ok, I think I have used the command where you press a letter on your keyboard and it shows you the keycode, but I'm trying to find the list that shows all the keycodes, so I can I some to my custom keyboard configuration
<gchristensen> benwaffle[m]: what revision exactly? git rev-parse HEAD
<benwaffle[m]> 6e5caa3f8ac48750233ef82a94825be238940825
<simpson> scientist: It depends on your particular keyboard!
<gchristensen> benwaffle[m]: and what output do you see?
<benwaffle[m]> for what
<benwaffle[m]> hyperfekt: `error: file 'nixpkgs-unstable' was not found in the Nix search path (add it using $NIX_PATH or -I), at (string):1:13`
<gchristensen> you're running nix-build . -A openssl-1_1 right? when you do that, what do you see?
<gchristensen> can you paste the log?
<benwaffle[m]> it builds normally, but it builds a lot of packages
<benwaffle[m]> i will paste it
<hyperfekt> benwaffle[m]: Do nix-channel --add nixpkgs-unstable https://nixos.org/channels/nixpkgs-unstable followed by nix-channel --update beforehand

<benwaffle[m]> its just 'nixpkgs' on my system
<scientist> simpson: well, I am using a custom keyboard layout, are you talking about my keyboard model ?
<benwaffle[m]> sweet it's only building openssl now
<hyperfekt> yeah exactly, we just import a channel so we can use it to call the package
<hyperfekt> benwaffle[m]: nice!
<benwaffle[m]> @gc
<gchristensen> heh yeah that is weird
<gchristensen> on eef63417d46c2b093ecce0bf07411a2ae0bbbb1e with your patch I only build openssl
<catern> is it reasonable to say that the original intention for channels and nix-env are pretty much obsolete? everyone's just using nixpkgs and not other channels, and the whole channels stuff seems pretty weird - git is better
<jcob> Hey all! Im considering switching to nixos and I have a few questions. 1. The only program that really matters on my computer is emacs. Within emacs, I am very happy with the straight package manager for managing my emacs packages. They all end up in ~/.emacs.d/straight. Would I be able to use this with nix?
<simpson> scientist: I'm talking about the actual hardware, yes. It is difficult to predict the raw keycodes without actually checking using xev or similar.
<gchristensen> catern: I don't care for nix-env, but I do like and use channels -- I think it would be risky to conclude they're obsolete
<mdash> jcob: You could but it's much nicer to configure it via nix expressions
<simpson> catern: I've had a couple multi-channel setups; back when the Monte project ran its own Hydra, we had a channel just for the Hydra. (These days we push to Cachix.)
<hyperfekt> jcob: I don't know straight but it sounds like it's entirely confined to your home directory. NixOS shouldn't interfere with that in the slightest. NixOS will only manage emacs itself (if you let it).
<mdash> jcob: not least because it's integrated with everything else and so you can manage dependencies on non-elisp programs/libraries in exactly the same way
<jcob> oh great thanks mdash and hyperfekt !
<scientist> simpson: so what is the command to see my the keyboard type of my hardware ?
<catern> gchristensen: simpson: but you just use them for user-level stuff, right? packages you want to install and use for interactive/non-development purposes?
<jcob> And my second q is related to the first: how well does nix play with programming language package managers like cargo and pip?
<simpson> scientist: No idea, sorry; I don't really know much about individual keyboards.

<simpson> catern: We had had at least one person who used the channels as intended and installed a Monte into their user profile.

wedens has quit [Quit: Connection closed for inactivity]
<hyperfekt> catern: I think channels would become very interesting the moment we can confine a cache to only provide some packages, so you can actually use them without trusting the package author with your whole system.
<hyperfekt> Right now I'd be wary to just add someone's cache, but I also don't want to build all my software from source.
<benwaffle[m]> do some people not use nix-env?
<gchristensen> I would say most people here avoid nix-env, preferring nix-shell and environment.systemPackages, or home-manager
<hyperfekt> benwaffle[m]: I don't think I've ever entered the nix-env command into my terminal outside of the installation ISO.
<__monty__> benwaffle[m]: It's fine if you're not on NixOS though.
<benwaffle[m]> I've just been using `nix-env -i` as a replacement for brew
<__monty__> That's fine, though you should be using nix-env -iA.

<benwaffle[m]> why -A? e.g. `nix-env -i vim` works fine

<betaboon> on a nixos18.09 install playonlinux complains that it cant load libGL.so. any hints what I'm doing wrong ?
<benwaffle[m]> hmm....ok. Maybe the manual should have that?
<gchristensen> benwaffle[m]: I agree =)
<hyperfekt> Anyone know how I can link a bunch of files into the current working directory? 'ln -s path/* .' works in my shell but not in the builder (ln: failed to create symbolic link './.': File exists)
<gchristensen> what if you change it to path/* ./
<jcob> Does nix have something where you can fetch a package but rather than fetching the package itself you fetch the recipie
<jcob> Im assuming the answer is yes
<hyperfekt> benwaffle[m]: Also, as I recently learned, you can use nix search to fidn the attribute name for a package to give to nix-env -iA
<gchristensen> jcob: nix doesn't fetch anything without knowing how to build it, so you probably already _have_ the instructions! :)
<benwaffle[m]> yeah `nix search` is nice
<hyperfekt> gchristensen: same error :/
<benwaffle[m]> nix is kinda hard to learn. why is there no `nix install`?
<jcob> gchristensen: in that case, what would you do to change the build instructions? Find them and change them and reinstall>
<jcob> ?
<emily> benwaffle[m]: because nobody wrote one; also because imperative package management kinda sucks when you can avoid it
<gchristensen> benwaffle[m]: nix's UI is a beta "2.0" interface, without all the functionality of the 1.0 interface ported over.
<emily> I don't use nix-env at all
<gchristensen> jcob: are you on nixos or no?
<jcob> gchristensen: no, but I plan to be in the near future
<benwaffle[m]> is there a doc or blog post or talk explaining how to think about nix and the ways in which it can be used?
<gchristensen> jcob: `nix edit nixpkgs.vim` for example, will open the instructions in your editor (but read-only probably)
<gchristensen> jcob: after that, best thing to do is git clone the repo, and edit it from there
<MichaelRaskin> benwaffle: I think, in a sense there are _multiple_ implementations of nix install

<gchristensen> probably just want to install it
<gchristensen> that is fine, I'd do the same thing if I wasn't on nixos
<benwaffle[m]> or use home-manager?
<MichaelRaskin> I dunno, I build a few environments with buildEnv, and add some of them to PATH
<bgamari> how does one convince nix-instantiate not to include !$OUTPUT suffixes in its output?
Makaveli7 has joined #nixos
<bgamari> for instance, I see
<bgamari> /nix/store/3nj27n45sl1sr2yv7i2dhm0jyqkxhcnr-gnugrep-3.3.drv!info
<bgamari> in its output
<hyperfekt> benwaffle[m]: You can do any of those, nix-env is for installing imperatively, nix-shell / nix run for doing it ephemereally and home-manager for doing it declaratively
<bgamari> which isn't a valid derivation path in the eyes of nix-store
<matix> today I learned about nix edit
<matix> gchristensen: thanks
<MichaelRaskin> bgamari: what exact command are you running
<bgamari> MichaelRaskin, nix-instantiate --quiet scripts/build-all.nix --arg bindistTarball $GHC_TARBALL -A buildDepends
<MichaelRaskin> Hm.
<gchristensen> and what do you want to get?
JonReed has quit [Ping timeout: 256 seconds]
<MichaelRaskin> My nix-store -r does accept !$output
<bgamari> gchristensen, just plain derivations unadorned with output suffixes
<bgamari> the full command line is
<gchristensen> I've never seen !$output before, and still can't ...
<bgamari> nix-store --export $(nix-store -qR --include-outputs $(nix-instantiate --quiet scripts/build-all.nix --arg bindistTarball $GHC_TARBALL -A buildDepends)) > store.nar
<bgamari> - nix-build scripts/build-all.nix
<bgamari> (ignore the second line)
<gchristensen> ah: nix-instantiate '<nixpkgs>' -A openssl.dev
<bgamari> right
<bgamari> so the buildDepends derivation mentioned above includes the buildInputs of another derivation
<bgamari> essentially I just want to cache everything necessary to build that derivation
<bgamari> in a NAR
<gchristensen> I've done this to convince some CI system to cache before
<betaboon> anyone has any hints on getting playonlinux to work ?

<bgamari> or a mixture of the two
<gchristensen> I agree, having a "CI Mode" which automatically uploaded everything to a binary cache would be really nice

<benwaffle[m]> now that i have rebuilt openssl, how do i make curl use those libs
<catern> bgamari: gchristensen: I'm not sure I understand the CI problem you're talking about, what is this?
<catern> you want a CI system to cache deps? doesn't it already do that as long as you don't GC too aggressively?
<gchristensen> not if you're using Travis
<bgamari> right
<bgamari> or docker
<catern> huh okay so how do you work around this for travis or docker?
<gchristensen> very ugly ways, like exporting the nix store at the end and re-importing it at the beginning
<bgamari> catern, pretty much any CI system worth its salt will have some sort of cache facility
<bgamari> where you can tell it to preserve a file across builds
<catern> okay, so then why do you need to get all the build-time deps of a package? that sounds like that should work?
<bgamari> the plan is to archive allof the build-time deps of the thing being tested to a NAR at the end of the build
<bgamari> and import that NAR at the beginning of later builds
<catern> but why not just grab the entire store? then that's nice and generic

<bgamari> catern, because it's much larger than the bits that I need
o1lo01ol1o has quit [Remote host closed the connection]
<catern> why? shouldn't the only thing in the store be build deps and the actual output? (you can delete the actual output I suppose if it's really so big)
<bgamari> the idea in my case is to build a subset of hackage with a GHC binary distribution
<bgamari> so the only build dependencies that I really need are cabal2nix and jailbreak-cabal
<bgamari> but the CI job may produce tens of gigabytes of other derivations
<hyperfekt> mkDerivation wrecking me so hard again I'm considering just using runCommand instead, ironically
<catern> i see
<catern> a CI mode like gchristensen mentions wouldn't help with that though
<catern> because it would upload those tens of gigabytes of output derivations
<catern> along with everything else
<gchristensen> well it'd also be able to fetch the pre-built ones
<catern> I assume the output derivations change every time or something
<gchristensen> not for many of them
<catern> otherwise I go back to asking why not just copy the entire store
o1lo01ol1o has joined #nixos
<catern> that's isomorphic to a CI mode I think
<bgamari> I'm actually not entirely sure I understand what is meant by "CI mode"
<bgamari> really what I want is a way to take a set of derivations and collector all of their build dependencies
<bgamari> collect*
<catern> but is that really what you want? :)
<catern> sorry to XY problem you
<bgamari> quite alright
<bgamari> I think so
<gchristensen> something to mirror hydra's behavior , bgamari, of uploading everything built -- not just the end result of what built.
<gchristensen> and as it goes -- not as a big stop-the-world phase at the end
<catern> (I don't have this problem because I run all my builds on a persistent machine with a persistent disk)
<bgamari> fair
<bgamari> yeah, I'm actually not sure that will help me
<gchristensen> no?
<bgamari> well, because I don't want to upload everything
<gchristensen> none of the builds would be cache-hits?
<bgamari> every build will be done with a new GHC binary distribution
<gchristensen> ah, heh
<bgamari> so very few will be cache hits
<bgamari> in my case the only things that will be cache hits are cabal2nix and jailbreak-cabal
<bgamari> but those two unfortunately take a non-trivial amount of work to build
<bgamari> it currently takes around 30 minutes just to get to beginning the interesting testing
<bgamari> because of this
<gchristensen> well there you go, those'd be two significant ones to run in a hypothetical --ci-mode
mounty has quit [Ping timeout: 240 seconds]
<bgamari> yes
<bgamari> I mean in principle I could just NAR up those two derivations
<bgamari> and that was my first attempt
<bgamari> but unfortunately I can't figure out how to reach the precise cabal2nix and jailbreak-cabal derivations that my builds are using
JosW has joined #nixos
<benwaffle[m]> so I think i have this issue: openssl builds v1.0.2q and v1.1.1a. I need curl to link against v1.1.1a. How do i do this?
<bgamari> catern, so anyways, perhaps my real problem is that
<bgamari> I can't find an easy way to identify an attribute path to reach a given derivation
<joko> benwaffle[m]: try adding (curl.override { openssl = openssl_1_1; })
<catern> gchristensen: I guess this notion of "CI mode" would ideally come from being able to list a bunch of Stores that any builds should be uploaded to. That's kind of a very natural inverse of listing a bunch of Stores to use as binary caches

<hyperfekt> gchristensen: That's what the --follow-symlinks option is there for, at least in theory.

<growpotkin> yeah when I googled `pdf2text` i didn't get any hits, but I am positive I've had it on an old machine or something
<growpotkin> it's in my muscle memory lol
<jabranham> growpotkin: wikipedia says pdftotext usually comes from poppler https://en.wikipedia.org/wiki/Pdftotext

<ddellacosta> can anyone tell how to (or where to find docs for how to) patch a transitive dependency in a Haskell package? I'm trying to figure out how to work around this: https://github.com/commercialhaskell/stackage/issues/4289

<lejonet> Hmmm, if I want a package to have a symlink in it that goes to a rw directory, is that possible to do? (trying to create a private package for a homepage, that has a file area, so kind of need to be able to place files there without needing to remake the package everytime :P )
<matix> lejonet: of course, your app could even hardcode the path directly, like for example most programs use /var
Ariakenom has quit [Quit: Leaving]
<lejonet> matix: yeah, that is what I'm gonna use, /var/www as the base, so I guess I could just add a symlink to the package that points to a location in /var somewhere, don't ask me why I didn't think about that... (the target of a symlink is allowed to not exist when the symlink is created...)
<matix> lejonet: the build is pure even if some symlinks point to rw files since the build output only contains the *contents* of the symlink (which is the path that it points to) and that doesn't change
<lejonet> matix: indeed, brainfart from me :P
* lejonet goes and hides in the corner

<omnipotententity> Potentially stupid graphics configuration question. I have two nvidia cards connected to three monitors. I only have display on the two monitors connected to the primary card. Previously, I had used an nvidia configuration tool to setup sharing through... SLI I think? It was several years ago the last time I seriously tinkered with my setup. What's the correct way to do this in NixOS?
<omnipotententity> Looks like it's "Base Mosaic," how do I do this from nix rather than having state within the nvidia-settings utility?
