Do you have any experience trying to run a pyqgis standalone app on NixOS?
No, but I would be interested to investigate this use case once I have some free time.

@autra:trancart.euautraHi! A colleague of mine is planning to add the python packages "earcut" and "py3dtiles" (I'm also a maintainer of the last one). Is it ok if the geospatial team is maintainer of both?09:52:02

Yes, sure. Go for it.

@autra:trancart.euautra Ivan Mincik (imincik): once there is no dependency to it any more, we'll be able to drop geos 3.9 from nixpkgs right? (only django seems to depend on it right now) 21:12:57

Looks like this question is missing some context - what is the package in question ?
04:37:09
@autra:trancart.euautraGeos 3.9, (well it's called geos_3_9 actually, as opposed to "geos", which is 3.12.1 currently)04:55:11

Geos 3.9, (well it's called geos_3_9 actually, as opposed to "geos", which is 3.12.1 currently)
Thanks, I agree. We should drop old geos once nothing depends on it.

@autra:trancart.euautra Hi everyone! Where can I find the correct doc for ryantm bot that creates update PR? I don't seem to find a piece of doc that explains what I observe in nixpkgs. For instance, this doc and this one seems to imply we need a passthru.updateScript. That is what I see when I execute nix-shell maintainers/scripts/update.nix --argstr maintainer autra for instance. But I've seen some PR for proj opened by this bot, without proj having such a script. What's going on? 😆 07:20:18

No idea other than https://github.com/nix-community/nixpkgs-update
11:54:57
@autra:trancart.euautraThanks! Ok I need to dig to understand then :-)13:08:07
@imincik:matrix.orgIvan Mincik (imincik)Let me know if you find something13:14:53
@autra:trancart.euautra Ivan Mincik (imincik): at least for python packages, a passthru.updateScript is automatically setup on derivation that don't have it by mkPythonDerivation: https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/interpreters/python/mk-python-derivation.nix#L223 17:13:53
@autra:trancart.euautrafollowing stuff: https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/interpreters/python/update-python-libraries/default.nix and https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/interpreters/python/update-python-libraries/update-python-libraries.py17:16:20
@autra:trancart.euautrawhich in turn seems to use the fetcher to check if a new version is published :-)17:16:41
@autra:trancart.euautraneat!17:16:56
@autra:trancart.euautrait doesn't explain why this bot didn't update mapclassify for instance, but well...17:42:57
@imincik:matrix.orgIvan Mincik (imincik) I think update script is not mandatory. In many trivial cases update bot can just check latest release and create PR without update script. 18:41:25
@imincik:matrix.orgIvan Mincik (imincik) Also, sometimes it takes very long time until update bot creates PR after new release. 18:44:37

Ah matrix probably treats uploads ephemerally

It might only consider releases, not tags though (I still need to debug a bit to be extra sure of that). And apparently, only github is supported now.

We have broken cross compilation for libspatialite, librasterlite2, librttopo and grass, any ideas how to fix?
