Add developer docs?
Problem
It's not obvious how to run a custom version of Wingpanel. The readme simply states to run io.elementary.wingpanel which won't work.
Wingpanel used to be started and kept alive by Cerbere. I don't think it's managed by SystemD?
- I can't find .service files in the repo.
- I can't find a wingpanel service under
cd /etc/systemd/system. -
systemctl list-unit-files | grep wingpanelreturns no results.
There are no wingpanel docs under https://docs.elementary.io/develop.
Simply killing it and booting it from terminal freezes my whole system.
killall io.elementary.wingpanel && G_MESSAGES_DEBUG=all io.elementary.wingpanel
Proposal
Add a few lines to the readme on how to start a custom version. This would probably mean including how it's currently managed and how to stop it from automatically restarting when it's killed.
Prior Art (Optional)
No response
The process is kept alive by Gala these days as are all shell components.
We probably should implement glib.application's replacement functionality the same as we've done in a few other projects

Good to know. But I can't find documentation on Gala and shell components either.
Can someone please share how to debug Wingpanel?
I'm experiencing issues like elementary/wingpanel#600 and elementary/gala#2506 which have gone unanswered. I'd like to look into them but don't know where to start without some minimal docs.
If by "debug" you mean "see logs" you can use journalctl
Personally when working on the panel or indicators I just install it 😅
But then we can't set G_MESSAGES_DEBUG=all?
Also I couldn't find gala or wingpanel services? (ystemctl | grep gala) So I'm not sure what to follow using journalctl?
Closing because it's not currently possible to launch wingpanel from terminal. If you need live logs, you can see them with journalctl --no-pager --follow | grep io.elementary.w
Thanks for sharing how to get to the logs. That would be a great item to add to the Readme (dev docs).
But what about increasing the debug level?
@peteruithoven You can add arguments and environmental variables by adding them to wingpanel's entry in /etc/xdg/io.elementary.desktop.wm.shell
Great. Another non obvious thing that would be great to add to dev docs 😇
Yeah I wanna reopen just so we remember to add a wiki page or a contributing.md or something
