Distro agnostic packages like flatpaks and appimages have become extremely popular over the past few years, yet they seem to get a lot of dirt thrown on them because they are super bloated (since they bring all their dependencies with them).
NixPkgs are also distro agnostic, but they are about as light as regular system packages (.deb/.rpm/.PKG) all the while having an impressive 80 000 packages in their repos.
I don’t get why more people aren’t using them, sure they do need some tweaking but so do flatpaks, my main theory is that there are no graphical installer for them and the CLI installer is lacking (no progress bar, no ETA, strange syntax) I’m also scared that there is a downside to them I dont know about.
I maintain some software, and Nix is by far the hardest to deal with. To package config files are relatively complex, and to submit a package you have to download the entire Nix repo, which is huge. Getting a package to build correctly can be a challenge.
It’s a pretty large ask for software contributors, who may have to iteract with a half dozen different distros. Now, you could say, leave it to the distro people to do the packaging, but it remains a barrier for entry and is by nature exclusive.
I don’t use NixOS, so I have little motivation to stay conversant with Nix and, frankly, it’s so demanding I don’t bother anymore. I can make RPM, deb, and aur packages trivially, and without having to hold Gb of some package repo (which I otherwise don’t use) on my disk.
If you maintain upstream software and do not have an interest in learning and using Nix, please don’t put the burden of packaging software in Nix onto yourself. Nobody in their right mind would expect you to package anything for a dozen distros; that’s not how distros are supposed to work.
Leave it to someone who is interested to package your software in Nixpkgs. Your “job” is to make your software better and provide a sane way to build your software that packagers can rely on (i.e. no assumptions where things are or are supposed to go, document your dependencies and build processes).
If you do want to go the extra mile, offer your help in assisting packaging in the appropriate channels. You know the technical details of your software and Nix users how Nix packaging works but the reverse mostly isn’t true, so cross-pollination can be super helpful here.
Even just things like testing that your software works as you expect when the packaging is touched in some way (i.e. an update) is incredibly helpful. (If saw a package update PR with the upstream maintainer’s approval stating that it works as they expect, I’d merge immediately.)
If packaging for Nix is a burden for you, please just open an issue on Nixpkgs with links to your packaging/build documentation and let someone else do it for you.
As a Nixpkgs committer, I’d much rather have someone invested in Nix build and maintain a package than an upstream maintainer who somehow feels obligated to do so but has no experience or actual interest as the former is more likely to produce good code and keep maintaining the package.
Sure. My point is that it’s trivial to make and test packages for many distributions; it is harder to do so for Nix. It tends to get your software out there and used faster if you bootstrap the packaging - immediately, if you have an AUR account.
IMHO, Nix is unreasonably harder. There are frequently small projects that don’t get packaged for most distros. When I encounter these, I have a couple of options:
The third option is preferrable to the others, for a variety of reasons, and it’s easy on most distros. On Arch, I might submit the package to AUR, but I’ll often just make a -git package and install it locally.
git clone --depth 1will clone a git repo without older stuff. Without this, the nixpkgs git repo is like 13-14 GB, but with a depth of 1, it’s only 200 mb.
