cq-editor: init at 0.6.2 by cjshearer · Pull Request #486070 · NixOS/nixpkgs

cjshearer · 2026-02-01T22:45:29Z

Adds cq-editor, cadquery, and their dependencies.

The latest attempt for some of these dependencies (notably cadquery/cadquery-ocp) stalled in this PR.

Note that while previous packagers (including myself) attempted to codegen the OCP python bindings, I have chosen here to take the simpler and more reliable approach of using the python bindings from the GitHub releases for OCP (which we then build).

I recognize that this approach does not cover darwin, but I do not have a Mac to test on anyway. If someone would like to add Mac support, I would encourage them to try, but suggest that this should be done in a follow-up PR; this PR is massive as-is.

If someone else with experience packaging this (@tnytown, @vincentbernat, @marcus7070) would like to jump in as a maintainer for these, please feel free!

Also tagging previous reviewers: @Sigmanificient, @qbisi.

Hi @cjshearer, can you use the trame feature of cadquery in jupyter notebook, and check if we need this patch for trame/trame-client: https://github.com/qbisi/nur-fem/blob/master/pkgs/python-by-name/trame/copytree-writable.patch.

cjshearer · 2026-02-01T23:20:50Z

@qbisi I haven't used a jupyter notebook in a long time, especially not on nixpkgs - is there some kind of existing example you could refer me to, so that I can test that?

Also, do you think that would that require packaging trame-jupyter-extension as well? If so, I'd be worried about scope-creep; my goal wasn't to make each dependency work for everything, but to get a modern cadquery/cq-editor version back in nixpkgs.

Maybe this one: CadQuery/cadquery#1786

Oh, I understand now! Yeah, I tested that.

Test script

#! /usr/bin/env nix-shell
#! nix-shell -I nixpkgs=. -i "python3 -I" -p "python3.withPackages(p: with p; [ cadquery ])"
from cadquery.fig import Figure
from cadquery.func import sphere, torus
from time import sleep

# this starts a server and opens a browser tab
fig = Figure()

sleep(5)

# we can use show, the API is fluent
fig.show(torus(10, 2), color='violet').show(sphere(5))

sleep(5)

# zoom to fit
fig.fit()

sleep(5)

# clear
fig.clear()

sleep(5)

@cjshearer with #442540, we can create a python venv with some system python packages from nixpkgs while others from pypi.

The key to use cq-editor is to package the hard c dep cadquery-ocp in nixpkgs, while we can install other pure python/javascript pacakges from pypi. Maintaing trame* packages can be painfull jobs as these projects are managed/published by npm's semantic-release which is unfriendly to linux distro maintainers. But i am not against that you take the responsibility to package all these depdenencies cq-editor need in nixpkgs.

…from pypi These dependencies contain pure python and js, so we can avoid the complexity of packing them from git without patching any binaries.

It's time to go cadquery-ocp-7.9.3.0 directly with #486359

cjshearer · 2026-02-08T17:55:07Z

Ah, that's why cadquery-ocp failed after rebasing on master 😆. I'll get right on that.

cjshearer · 2026-02-08T18:44:45Z

@qbisi, #486359 is actually somewhat of a problem - upstream cadquery still depends on ocp 7.8.1. Just like the AUR package, this would put us ahead of upstream (cadquery PR for OCP 7.9), causing cadquery to fail during import:

I'll have to override opencascade's version in cadquery-ocp and stick with 7.8.1.2.

qbisi · 2026-02-08T23:44:13Z

Maybe we can wait for CadQuery/cadquery#1968. I would also prefer generating cadquery-ocp source with pywrap based on opencascad-occt 7.9.3 like @tnytown's work in #433247. Vtk/opencascade-occt (Not vtk-full) in nixpkgs does not neccessary have mpi related symbol, it's better we dump the symbol and generate source from vtk/opencascade-occt in nixpkgs.
The recipe will be much cleaner after we bump opencascade-occt to 7.9.3.
I will open a draft pr relating cadquery-ocp later.

tnytown · 2026-02-09T04:48:48Z

Hi, good to see work on this constellation of packages progressing! Let me know if any help is needed with cadquery-ocp; I have some local work that I'll tidy up and push.

tnytown · 2026-02-10T05:46:09Z

The tip at #433247 has a working cadquery-ocp, although there are failing tests there that need to be investigated.
