 atagen | how would I enumerate attrs? for example, if I have:
foo = {
bar = { baz = false; };
rab = { zab = true; };
};
how can I process this to get
foo = {
bar = { n = 0; baz = false; };
rab = { n = 1; zab = true; };
};
```?

| atagen | I don't care about the order of evaluation, only that n is unique for each member | 02:19:01 |
 infinisil | atagen: There's a PR proposing imapAttrs: https://github.com/NixOS/nixpkgs/pull/270049 | 02:20:59 |
 emily | nix-repl> :p lib.listToAttrs (lib.imap0 (n: {name, value}: {inherit name; value = value // { inherit n; }; }) (lib.attrsToList {a = {}; b = {};}))
{
a = { n = 0; };
b = { n = 1; };
}

| emily | (why do you want this?) | 02:21:58 |
| atagen | In reply to @emilazy:matrix.org
(why do you want this?) I have a home-manager option that generates firefox profiles w userchrome removed, unique .desktop files etc to make pseudo-PWAs - the IDs need to be unique and sequential for firefox to respect all entries in the profile ini | 02:24:54 |
| emily | I see | 02:25:20 |
| emily | you might want to skip the listToAttrs part depending on your usecase | 02:25:28 |
| emily | also, since there's no ordering guarantees, if renumbering would matter at all you might just want it to be a list to begin with | 02:25:54 |
| atagen | I appreciate the help, I'll have a poke around at it | 02:25:55 |
| atagen | anything beats setting them manually at each site | 02:26:32 |

also, since there's no ordering guarantees, if renumbering would matter at all you might just want it to be a list to begin with though hmm yeah | 02:26:36 |
 @adis:blad.is | Attrsets are sorted | 02:27:03 |
| atagen | now I think about it, if I remove one and the number decrements, firefox will probably start using the data of the old profile from the wrong app | 02:27:08 |
| @adis:blad.is | So you'll get numbering in lexicographical order | 02:27:20 |
| atagen | * now I think about it, if I remove one and the number decrements, firefox will probably start using the data of the old profile from the wrong app.. perhaps I can do some symlink crimes based on app names and some stateful stuff in home dir | 02:29:21 |

Attrsets are sorted uh, TIL | 02:30:38 |

now I think about it, if I remove one and the number decrements, firefox will probably start using the data of the old profile from the wrong app.. perhaps I can do some symlink crimes based on app names and some stateful stuff in home dir I'm confused, surely the reason Firefox profile directories are named after key mashes is to avoid this? | 02:31:15 |
| emily | are you sure the ordering is not just to determine the list some UI presents or something? | 02:31:37 |
| atagen | I honestly have no idea | 02:31:50 |
| atagen | hmm, they do have a Path key in the INI, but I don't know if I have simple access to that part of the hm firefox machinery lol | 02:32:51 |
