The freecad-ppd from ppd

Update to latest VTK 9.1.0

https://github.com/Kitware/VTK/releases/tag/v9.1.0

We need to make sure this works on edge.

FEM - No module named 'yaml'

When running FEM inside Freecad, the subjects error message appears.

I know the meaning of the error message. It means that the Freecad is unable to locate python's yaml -module.

What I don't know, what is the correct way to add dependency to snap freacad. Since I have in local system python-yaml installed, but it is not used by snap instances.

Upstream dependency libspnav has released a new minor version (v0.3)

It fixes an annoying issue
https://forum.freecadweb.org/viewtopic.php?f=8&t=65632

issues with older xdg-desktop-portal versions

Older portal versions proxy everything through the document portal.

Problems:

Files get lost when saving because FreeCAD appends a suffix, which is not allowed via the document portal
Opening files with external links fail because the externally linked files are not available via the document portal

Possible solutions:

simply do not use the native file dialog (ugly, can access fewer locations on the system)
reject paths starting with /run/user and switch to the internal dialog at runtime. Would have to be patched upstream to be maintainable. Also an ugly solution.

Problem with main menu

Hello,
I just encountered your snap and gave it a go since official snap is on some old revision. But I have a question about main menu - it works on 'freecad' snap, but on 'freecad-ppd' is not (my DE is Unity and I am on Ubuntu 20.04). Do you have idea why that would be?
'freecad stable':

'freecad-ppd stable'

Desktop portal file dialogs open unfocused

It's a bug in Qt: https://bugs.kde.org/show_bug.cgi?id=444873

The solution for the KDE neon packages is proposed here: https://invent.kde.org/neon/qt/qtbase/-/merge_requests/3

FAQ: Why are there two snaps? What's the difference to the freecad snap?

Read those on the forum:

This is the other vanilla snap:

Network Drive Access with Snap

I don't know if this is a known issue, or maybe due to the nature of a snap package, it is more of a feature than a bug or issue, but when using the snap image, I lost the ability to save to an NFS mounted network drive which limited my use case for the program. Issue originally added to:

Question: snapd doesn't tell me that it's updating freecad-ppd edge in the background. How can i make it?

Been enjoying freecad-ppd edge but am mystified by how it stays updated in the background without telling me. I tried searching for an answer but did find one. Can you share with me what I need to know? Is there a way for my system to show me what is usually kept silent and in the background?

dot works in freecad-ppd (I can render dot files to svg just fine)

Updating to python 3.9 so we can match Blender's python version?

Hey @ppd there is an issue with blender interoperability that is due to conflicting python versions. See nortikin/sverchok#4005

The AppImage is currently using 3.9.12

Is this something we can consider for Snap edge ?

Using snap to test python related code commits

Is there a way to modify the internals of freecad-ppd edge to test code (in a way that won't interrupt daily updates?)

For example, the AppImage allows for this: https://wiki.freecad.org/AppImage#Modifying_AppImages

pip: Switch to --user instead of --target

See freecad-realthunder

Benefits:

Compatibility with Assembly3
Can actually uninstall packages

Offtopic: Could you make and 'edge' for Scribus ?

Sorry to off-topic post this here. But I was wondering if you'd be interested in creating a snap for Scribus edge ?
