 emily | hm, function call vs. string interpolation maybe? | 20:57:37 |

| Artturin | Can't do or (throw "cups-idprt-barcode: No prebuilt filters for system: ${stdenvNoCC.hostPlatform.system}") with getAttr so will have to use the interpolation | 21:30:58 |
| Artturin | Or
arches = {

x86-linux = "x86";
};
arch =
if (builtins.hasAttr stdenvNoCC.hostPlatform.system arches) then
builtins.getAttr (stdenvNoCC.hostPlatform.system) arches
else
throw "Not supported on ${stdenvNoCC.hostPlatform.system}";
but this is ugly and also has worse stats

| emily | would be nice if you could say foo.(stdenvNoCC.…) | 22:07:21 |

| Pol | Heya!
I'm working on this PR https://github.com/hercules-ci/flake.parts-website/pull/1096 and I'm trying to address the first point noted by Robert Hensing (roberth) https://github.com/hercules-ci/flake.parts-website/pull/1096#issuecomment-2378900576
I would like to have some directions on how to do such a function.
I saw that efforts were made in https://github.com/NixOS/nixpkgs/issues/237776, figsoda proposed a function concatMapAttrsWith but I don't know how it could help me for the issue I have. | 12:11:15 |
| Pol | I'm basically looking for transforming such an attribute:
{
a = {
b = {
c = <derivation hello-2.12.1>;
};
into:
"a/b/c" = <derivation ...>;`
| 12:13:46 |
| Pol | * I'm basically looking for transforming such an attribute:
{
a = {
b = {
c = <derivation hello-2.12.1>;
};
};
};
into:
"a/b/c" = <derivation ...>;`
| 12:14:15 |
| Pol | * I'm basically looking for transforming such an attribute:
{
a = {
b = {
c = <derivation hello-2.12.1>;
};
};
};
into:
"a/b/c" = <derivation ...>;`
Knowing that the tree structure can be totally varying.
| 12:14:51 |
| Pol | I pushed this thing: https://github.com/drupol/pkgs-by-name-for-flake-parts/commit/baf7212a27ec1cb1a1139f8bbc78a184581a4bcd but I have the feeling that it could be simplified/improved using concatMapAttrWith. WDYT? | 12:29:08 |

I'm not sure if concatMapAttrsWith would be helpful in this particular case. I did the same thing in fenix to make nested package sets show up in flakes: code, but I just used concatMapAttrs directly | 15:45:18 |

 aleksana (force me to bed after 18:00 UTC) | Why is repl allowing if = 1 (can autocomplete if but can't get the value) but not a = { if = 1; }? | 02:49:18 |
| aleksana (force me to bed after 18:00 UTC) | I'm reading the lexer and parser but still can't understand why | 02:49:37 |
