4 years ago I have some experience with pip, go, jpm and cargo.
My current plans are as follows:
-
pip: automatically convert all deps into a set of source packages that turn into a single venv and install them similar to how our package meson works. I have prototyped something similar here https://github.com/andrewchambers/mummipy, so have some idea how to do it.
-
Go: Read a go.mod file and convert it into a build definition, tell go to build using go mod vendor
-
Janet similar to python, https://github.com/andrewchambers/jpm-to-hermes
-
Rust, Not too sure yet.
Brain dump:
If necessary I may trick some of these tools into thinking they are downloading from urls, while actually serving them fixed tarballs via a fake http proxy.
If the tool is not cooperative and doesn't have a notion of a globally installed library (like cargo), I may abandon the idea of sharing libraries between packages. I have no plan to implement something like carnix, even though other people can try if they wish.
I may consider splitting languages into their own repositories that are free to depend on hpkgs core.
In general, Hermes prefers to make a toolbox of small functions to do common operations, rather than make a framework to do everything.

A lot of language ecosystems nowadays have their own package managers, e.g. Janet->jpm, Go->go get, (Lua->LuaRocks), JS->npm, Rust->cargo, Nim->nimble, etc. etc. In some cases they're more of an optional helpful addition, like in case of LuaRocks IIUC; but in other cases like with Go, they seem ingrained deep enough that I find it hard to imagine to not use them. Do you have some plans/ideas you could share w.r.t. how to handle this merry company in hpkgs? I'm asking especially based on the fact that in nixpkgs the situation is IMO super messy and chaotic (as a lot of other things), due to their evolutionary & "prime mover" position. Hpkgs has the benefit of hindsight, and IIUC you have enough experience with NixOS that I would suspect you probably have some ideas/opinions how to maybe try and aproach this systematically & in some unified way? I skimmed through a few packages already in hpkgs but didn't seem to notice anything in this area yet.
