 raitobezarius | aloisw: you are super strong at rootcausing this sort of things ^, if you have some time (and desire), that'd be awesome ^
My bet is that this seems normal and is a stdenv machinery thing but not sure | 19:50:05 |
 niko ⚡️ | I can't reproduce it using the old cli, I'll try flakes but I doubt it'll affect anything. FWIW this is the derivation I'm trying
{stdenvNoCC }:
stdenvNoCC.mkDerivation (finalAttrs: {
pname = "repro";
version = "1";
src = ./.;
lol = finalAttrs.src;
buildPhase = ''
echo lol = "$lol"
echo lol = "${finalAttrs.src}"
'';
installPhase = ''
touch $out
'';
})
and the output is
Running phase: buildPhase
lol = /nix/store/jl7xm5g4yc8larsbyabf07db9p96ljrq-nix-repro
lol = /nix/store/jl7xm5g4yc8larsbyabf07db9p96ljrq-nix-repro

 aloisw | The problem is that src (and consequently, also finalAttrs.src and something) are not strings, but paths. Similar to string interpolation, builtins.derivation will always copy paths to the store, even if they already happen to point into the store. So all of $src, $something and ${finalAttrs.src} will point at the double-hash path (no idea how you got something else for the latter, did a builtins.toString sneak in somehow?). On the other hand, you determine the name of the unpacked source using your stripHash function (https://github.com/RossSmyth/press/blob/d3eb2b2deee2116609f938b08fc86a48850b99c4/src/buildTypstDocument.nix#L18-L23), which calls builtins.baseNameOf which operates on the original path. | 06:00:42 |
 Martin Häcker | Anyone at Fosdem and would like to meet up? | 10:11:01 |
|  hexchen (migrating to @hexchen:railwit.ch) changed their display name from hexchen to hexchen (migrating to @hexchen:railwit.ch). | 13:31:33 |

 jyrama | Funnily enough, the Nix room is both bigger and more overflowing. | 15:01:18 |
 jappie | Nix devroom in Janson next year? 👀 | 15:07:36 |

 K900 | AFAICT you're not banned at least | 21:06:51 |
 KFears (they/them) | In reply to @delroth:delroth.net
it is niche and an afterthought, the installables syntax in the new nix3 CLI is very tied to flakes, even though you could theoretically split them I would very much like the installables and "runnables" concept to be extracted from flakes | 21:06:56 |
| Sofie 🏳️⚧️ (she/her) | can you see did u receive the message? | 21:07:17 |
| K900 | Yes | 21:07:36 |
