Description nmset 2023-10-17 13:11:04 UTC

Hi,

The new 'class wizard' in kdevelop creates empty and unsaved files.

The preview in the first page of the wizard is empty also.

Since:

Version 5.12.230802 (23.08.2)

Running on:

Operating System: Arch Linux 
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.110.0
Qt Version: 5.15.11
Kernel Version: 6.5.7-arch1-1 (64-bit)
Graphics Platform: X11
This is observed on 2 machines.

Please note it's not about the 'new app wizard'.

Thank you.

This is likely a KArchive-related recent regression (not in KDevelop code, I think). Here is some of the output in systemd journal after trying to create a class from a template:
kdevplatform.language: could not open template "/usr/share/kdevfiletemplates/templates/c_gobject.tar.bz2"
...
kdevplatform.language: could not open template "/usr/share/kdevfiletemplates/templates/qwidget_pimpl.tar.bz2"
kdevplatform.language: Entry "class.h" is mentioned in group "Header" but is not present in the archive
kdevplatform.language: Entry "class.c" is mentioned in group "Implementation" but is not present in the archive
kdevplatform.language: Entry "class.cpp" is mentioned in group "Implementation" but is not present in the archive

Template-related KDevelop tests started failing recently with similar output. See also https://invent.kde.org/kdevelop/kdevelop/-/merge_requests/499.

I am getting this on opensuse tumbleweed as well. When I go to the folder via "Load template from file" the folder (/usr/share/kdevfiletemplates/templates for me) has nothing showing, despite both ls and dolphin showing the bzip archives.

I installed a template via ghns and it also failed with a similar message and a blank folder it its location (~/.local/share/kdevfiletemplates/templates)

Unzipping the installed template from ghns showed the .desktop files (but not the bzip archive) in the "Load template from file" picker window. Selecting the desktop file, once proper ownership and permissions were set, did nothing to add the template to the wizard. 

I also tried copying one of the default templates to ~/Downloads and unpacking it there. The file picker once again saw the .desktop but not .tar.bz2 files and selecting the .desktop file did not add the template, though no new messages appeared on the console.

Upon closing the wizard, I got a new message of
kdevplatform.language: Could not find a template archive for description ""   archive file ""

Comment 4 Igor Kushnir 2023-11-07 08:21:43 UTC

This is actually a regression in shared-mime-info 2.3. Fixed in KArchive 5.112.0 (https://commits.kde.org/karchive/4455503ce4910c65758138b44bc136de9fe32cd4).

Comment 5 Igor Kushnir 2023-11-21 08:55:27 UTC

The regression is fixed in shared-mime-info 2.4: https://gitlab.freedesktop.org/xdg/shared-mime-info/-/commit/918d2610830d52c6b13cf7f7e35f68dcb1438ee7

Yes, it works as expected now, thanks.
