hi, I'm starting a new NixOS installation after a year or so or using Nix and NixOS, and I already have a question at point 2 of the installation instructions.
<kandinski>
It says to add the master channel if I follow the master or unstable channel, and a 19.03 release if I follow a Nixpkgs version 19.03 channel. I always install stable on the system and then follow unstable on my /home/user. Does this mean I should follow https://github.com/rycee/home-manager/archive/master.tar.gz as well?
<rycee>
kandinski: Yeah, I believe so. Basically, if `<nixpkgs>` for you points to Nixpkgs unstable then you should use HM master.
<kandinski>
thanks, rycee
<rycee>
Np :-)

pie_: I had a look at the links a while ago but I didn't work on it any. offlinehacker made the nice PR using the http://kb.mozillazine.org/User.js_file technique. I don't know if he referenced this issue any.
<rycee>
Hmm, I'm not certain what you meant by "convert a nested attribute set". You mean to use `profiles.default.settings`?
<pie_>
not sure what you mean by profiles.default.settings, but this dotted stuff just reminds me strongly of configuration.nix settings
<rycee>
Aha, right. Yeah, the option could have the type `attrs` but that is a bit tricky w.r.t merging.
<rycee>
It would be great if there was a well-defined `recAttrsOf` type.
<rycee>
Then we could have used `recAttrsOf (either bool (either int str)` for this.
<pie_>
i was thinking just about the conversionto an output string side
<pie_>
i havent done much with modules / types yet, but tha tmakes sense
<pie_>
rycee, open an issue? xD
* pie_
too distracted with other things to think about this with any depth :v
<pie_>
would be cool if you added a note that we have a use case for this (?)
<pie_>
"all of the mozilla stuff" sounds at least somewhat significant to me#
<rycee>
Well, there it is even more general, like `types.config.json`.
<pie_>
sounds fine i guess. my initial thought is that the type checking and output generation are inevitable to separate
<pie_>
so we're really talking about two things i think?
<pie_>
nothing is stopping a possibly-foot-shooty "just serialize this attrset to a string"
<pie_>
just some kind of simple recursive fold (which is what i say about a lot of "simple" algorithms and then collapse into a whimpering heap :P)
<rycee>
pie_: Yeah, I'll add some more comments to this rfc. Will mention that as well.
* pie_
tries to draft up a simple implementation for the output
<pie_>
rycee, though i guess its also a question how much of the configuration semantics we want to duplicate in nix heh...
<rycee>
Ideally as little as possible, I would say :-)
<rycee>
The way the Firefox settings option is now I guess is the minimal but I agree that it would be nice to allow a more structures recursive attributes approach, as long as we could offer sane merging.
