Nixpkgs missing its Emacs packages

[Atemu]

Nixpkgs has packaged 254 ELPA and 4601 MELPA packages but none of them show up on repology.org.

They're available under the emacs{25,26}Packages attribute sets (https://search.nixos.org/packages?query=emacs26Packages&from=0&size=10000&sort=relevance&channel=unstable).

That's odd.

These definitely are available in Nixpkgs if you evaluate it and the new search page shows them aswell (see link in OP).

I've investigated a bit further and found that nodePackages, perlPackages, luaPackages and texlive packages are also missing.
Some of those do not show up in the new search page either.

I've also looked into how that JSON is generated. It's the result of nix-env -qa which I don't think is a very good source for repository information.
@samueldr @garbas, do we have better sources other than Nixpkgs itself?

Although, would making Repology evaluate Nixpkgs directly be feasible @AMDmi3? That'd be the most accurate source.

The issue is that adding a "sub package set" is costly for the packages search interface. Adding new packages into it made the issues with (the older, and the old) package search problematic.

We can look into producing a full list that is independently used for repology import (and other people's data scraping desires).

Definitely no. I won't do any complex parsing and depend on third party software.

That would be a solution.

Closing since there's nothing to do here on repology side.

Problem has been resolved!
