| Ern | Hello, I have a problem with reinstalling Lix on Darwin that I don't know how to solve. | 02:17:55 |
| Ern | My nix darwin install previously broke, so I uninstalled it. It left the _nixbld users behind, so I removed them. | 02:18:48 |
| Ern | I then tried to install lix with
curl -sSf -L https://install.lix.systems/lix | sh -s -- install | 02:19:21 |
| Ern | The installer prompted me to escalate privileges, which I did. The installer then threw this error. | 02:20:32 |

 holly [she/it] 🏳️⚧️ | i've seen discussion about this before, if i'm remembering correctly it's not implemented for nix3 cli in lix | 09:08:18 |
| opeik | darn, any reason why? it's very handy | 09:40:46 |
 Sofie 🏳️⚧️ (she/her) | this ^ | 10:05:13 |
 K900 | I think it's just that no one backported it from cppnix | 10:14:07 |
| K900 | And no one working on Lix wants to touch flake code that much | 10:14:18 |
 KFears 🏳️⚧️ (they/them) | I have attempted to backport it a while ago and it was a challenge. The code is not easy to understand, and I felt a lack of knowledge in both Lix and CppNix codebases to do it efficiently | 10:18:00 |
| K900 | I mean, there's a reason no one wants to touch the flake code :P | 10:18:54 |
| KFears 🏳️⚧️ (they/them) | Mhm, learned that firsthand | 10:19:31 |
| KFears 🏳️⚧️ (they/them) | (I also never knew how such shebangs are implemented, and this is a very specific amalgamation of checks that enables it, like I think the command needs to check its arguments and see how and where it's invoked and then manually read the next line of the file or something like that) | 10:21:06 |
| KFears 🏳️⚧️ (they/them) | (and I became kinda uncomfortable with doing this kind of feature in general, because of how special-case it is) | 10:21:35 |
| K900 | I mean honestly shebangs are just generally horribly cursed | 10:24:06 |
| KFears 🏳️⚧️ (they/them) | Mhm, that is the impression I got | 11:06:53 |
| KFears 🏳️⚧️ (they/them) | So I would aim instead to create some nice-r UX for using general Nix commands and/or code for scripts, than hacking together a shebang | 11:07:43 |
