ldlework: what do you want your nix-shell to do?
<vaibhavsagar>
if you've already built the thing then the binary will be available under result/, even inside your nix-shell
<ldlework>
vaibhavsagar what I mean is that I thought that nix-shell doesn't actually build the derivation
<ldlework>
it gets the build inputs and stuff installed, but doesn't acutally build the derivation
<vaibhavsagar>
yes, that's right

Is is possible to make NixOS run EXWM with my current .emacs in my home directory?
<disasm>
ldlework: yeah, that's correct, it won't build the derivation. That's why typically a nix-shell used for env isolation will have no source code in it, just a list of derivations that the shell depends on
rtjure has joined #nixos
<ldlework>
yeah
<iqubic>
Like, don't create a simple emacs init file to run EXWM with, just use my current .emacs
<disasm>
ldlework: it comes down to what you're trying to do, using nix-shell with a package will get you a build environment to manually build that package, using nix-shell with a stdenv.mkDerivation with no src and a bunch of build inputs will give you a shell with access to all those buildInputs.

NixOS was way easier to install than I expected. Took ~30 minutes on the first install (29 of which were, of course, configuring it for the first time)

Hi I'd like to create a RuneScape NXT client package for Nix, how do I try to build it? I've tried adding it to pkgs/games/runescape-launcher in the nixpkgs repo and running nix-build -A runescape-launcher from the root of the repo but that failed, didn't seem to recognize my new default.nix file existed. I then ran `nix-build --keep-failed --expr 'with import <nixpkgs> {}; callPackage ./default.nix {}'` from its subdirectory

and it too failed. If I need to give details as to how they failed I'll happily do so but I suspect I'm simply trying to build it the wrong way.

Nice. I figured KDE Plasma was responsible for a fair amount of the size of the live image.

If I run a nix-env -i foo on the Graphical Live disc will it stay persistent or is that just run in RAM? The defaul is missing a fair number of basic tools. :)

Well, I want to be able to use it as I would a normal install. Basically I'm looking to make a NixOS replacement for things like Puppy Linux or similar live medium distros.
<clever>
tanonym: oh, using a filesystem like zfs that supports compression may help
<clever>
gzip-9 can compress things pretty far
<tanonym>
This way I can work off it rather than having to carry my laptop around (at least until I can get my hands on something like a chromebook or HP Stream)
<clever>
at the cost of more cpu usage
<clever>
the non-persistant iso uses squashfs, which is read-only compression
<MichaelRaskin>
I would (and I actually mean did) just get a large enough USB drive.

Or even have a segregated approach like what the Amigas used to have where the OS lives on one ROM disk and applications are on a separate disk. Meaning if something infects your system you just reboot and since everything was run from volatile memory the compromise doesn't survive.
<tanonym>
ZFS, isn't that the FS from BSD variants?
<guillaum2>
clever: thank you, the link was really informative. My issue is that, for now, I don't want to pin the version of nixpkg used. I was thinking that the "channel" purpose was exactly to get updates of packages. My only issue is that the channel "nixpkgs" does not mean the same thing if you are on nixos or not.
<clever>
tanonym: android does the same thing, the os lives on a read-only /system and the user stuff on a writable /data
<tanonym>
Yeah. With version 5 of Android you can now have rootless rooting. So you can take advantage of apps that need root without actually needing write access to /system.
<tanonym>
Been looking at Material design specifications, a well laid out description of UI design.
<clever>
tanonym: all of the tmpfs based stuff in nixos, involves using a unionfs to merge a tmpfs and a squashfs
goibhniu has joined #nixos
<clever>
tanonym: but you could modify it, to union a writable and a read-only
<tanonym>
That will involve a bit of learning on my part :)
rtjure has joined #nixos
<clever>
tanonym: the issue though, is that when you do a major update and garbage collect, the read-only will become 90% garbage, that can never be deleted
<tanonym>
Right now compression is a priority.
<clever>
tanonym: and everything will be in the uncompressed writable layer
<clever>
tanonym: so a writable compressed filesystem, like zfs, will win
<tanonym>
Need to see how I can adapt some of the ideas from TinyCore to NixOS.
<tanonym>
Okay I can make rough sense of what the code is doing reading that over. I need to study up on my coding :D

Unode: but the nixos scripts for generating xorg packages where not aware of that merging, and used the deprecated external glamor, that still had the problem

which resulted in the old bug being present on nixos

a flash usb drive is slow as shit

infinisil, avn: but if you use copyKernels with /boot on the same FS as /, it will still copy it, and then grub doesnt have to deal with the insanity that is /nix/store/
<avn>
infinisil: yes, but it required if /boot is same as / and it is zfs
<clever>
infinisil: grub has trouble traversing /nix/store/ and copyKernels puts them into a simpler directory structure
<CrazedProgrammer>
tanonym: mount /boot and create the zpool and a new filesystem (for example zpool/root), set mountpoint=legacy on that filesystem and mount that filesystem on /

I could use some advice on packaging rust apps for nix. I'm packaging an app I wrote, and I've had to downgrade a few dependencies to match what's in the rustRegistry in nixos-unstable, since the versions that I had been using are newer than the last rustRegistry snapshot

yeah, I think once we get the modules to be less nixos-specific we'll have a stronger motivation to reoganize
<ghostyyy>
copumpkin, is that really a property specific to nixos though? any package manager with language packages could depend on postgres-dev or whatever
<gchristensen>
Nix is far more precise and correct
<ghostyyy>
what i would be interested in is some kind of automatic way to transform between eg cabal files and nix expressions, so that you could automatically keep them up to date and consistent with each other
<gchristensen>
it doesn't depend on "postgresl" but an exact postgresql
<gchristensen>
like cabal2nix?

ghostyyy: 1) language packages are generally a lot easier here (because we factor out the common crap and then writing new language packages is trivial) 2) you don't have to worry about conflicts

nixpkgs is a versioning scheme for the FOSS universe :P
<copumpkin>
doesn't have to be FOSS but mostly is right now
<ghostyyy>
i actually decided to use nixos over guix because of its more lenient stance on nonfree software
<copumpkin>
:)
<infinisil>
I need to try out guix, they're one lanugage for what nix currently uses bash/nix sounds pretty neat
<infinisil>
(ignore the english of that sentence)
<copumpkin>
:P

nix : bash :: haskell : IO
<copumpkin>
I see it as a good thing :P
<copumpkin>
not the bash
<copumpkin>
but the separation
<gchristensen>
same
rtjure has quit [(Ping timeout: 240 seconds)]
<copumpkin>
the bash isn't really fundamental, that's a nixpkgs choice
<infinisil>
Yeah, but it would be hella hard to get bash outta there
<copumpkin>
getting it out of nixpkgs sure
<infinisil>
and nothing good to replace it
<infinisil>
(convince me of the opposite please)
<copumpkin>
you could trivially be slinging around giant strings full o' python or ocaml in mkDerivation if you wanted to
<copumpkin>
bash just happens to be convenient for doing the sorts of things we like doing in builds
<gchristensen>
and it turns out a job control language is good for job control
<copumpkin>
like if it were python, we'd be throwing subprocess.check_output all over the place
<copumpkin>
and that's gross too
<copumpkin>
on the plus side, we could hide that away in a library and avoid doing it much of the time
<copumpkin>
but it's sort of a "smoothness of deviation from the norm" type argument
<infinisil>
If we could use libraries for stuff we use bash today, oh boy
<copumpkin>
we have bash libraries today ;)

Just have a look how terrible the setup hooks are (imo)
SovereignBleak has quit [(Quit: Connection closed for inactivity)]
<copumpkin>
yeah they're a bit too magical
<samueldr>
there's nothing using CEF in nixpkgs right now, right?
<copumpkin>
but anyway, starting a nixpkgs-v2 from scratch using packages from nixpkgs but writing package build specs in any language you want should be pretty easy
<copumpkin>
and nice experiments for figuring out nicer models of setup hooks and the like

"Oh you declared dontFixCMake? Well too bad, it's called dontFixCmake, I won't let you know though, because that's just an env var"

How about using the module system for mkDerivation
