Automatic extraction/requirements detection fails for dymoprint
spease opened this issue · comments
For some reason, even with the latest rev (8d90307), automatic everything fails with https://github.com/computerlyrik/dymoprint.
default.nix:
with (import <nixpkgs> {});
let
mach-nix = import (builtins.fetchGit {
url = "https://github.com/DavHau/mach-nix";
# ref = "refs/tags/3.5.0";
rev = "8d903072c7b5426d90bc42a008242c76590af916";
}) {
inherit pkgs;
pypiDataRev = "ba35683c35218acb5258b69a9916994979dc73a9";
pypiDataSha256 = "019m7vnykryf0lkqdfd7sgchmfffxij1vw2gvi5l15an8z3rfi2p";
};
in
mach-nix.buildPythonPackage {
pname = "dymoprint";
version = "1.4.1";
requirements = ''
importlib-metadata; python_version<"3.8"
appdirs
Pillow>=8.1.2,<10
PyQRCode>=1.2.1,<2
python-barcode>=0.13.1,<1
pyusb
PyQt6
PyQt6-tools
'';
src = ./.;
}
Note that PyQt6 and PyQt6-tools do not seem to exist, but it does not say this is the problem.
Unfortunately as part of the troubleshooting process I tried updating nix, so now I'm getting #549.
If I comment the pname,version,requirements out I get:

Please manually specify 'pname'
Digging deeper, after adding a workaround for #529 (PR incoming, I'm not certain about it though):
- this is a pyproject.toml project, and mach-nix currently can't read the requirements, you have to copy/paste/adjust them.
pyqt6 isn't in the source distribution part of pypi-deps-db ('"FileNotFoundError: [Errno 2] No such file or directory: 'setup.py'",).
The binaries apparently only go up to python 3.9, but mach-nix isn't seeing any of them from pypi-deps-db.
The nixpkgs PyQt6 in 23.05 is 6.5.0 which is too new for the last pypi-debs-db (it's currently not updating...). so you have to go to 22.11, but that's got 6.4.0 and the pyqt6-tools release on pypi needs 6.4.2. And 22.05 didn't have pyqt6 at all. So you need nixpkgs rev f519c1e43c38d6e27cc84c57709a309804d4fada.
And then you're missing pyqt6-qt6 which has no source distribution on pypi.
Sorry, gotta go do something else at this point.
Here's' the flake I got so far

That's pretty involved but it looks like you put a lot of effort into it. Will this be stable enough to submit to nixpkgs?
EDIT: And thanks
Unfortunately, mach-nix is all about 'import from derivation' - derivations computing what derivations are actually needed. That's a no-go in nixpkgs.
But of course, at the point where you have a working mach-nix setup, it's just mechanical to get it to something nixpkgs can accept.
