Ok, I think I fixed both: https://build.opensuse.org/package/show/home:fbonazzi/waybar I have submitted the date library to Factory (SR#1039397). Unfortunately now that I've removed the hhdate package from my home project, waybar does not build anymore. Do I need to wait until hhdate hits Factory or could I make it build against the devel project somehow (devel:libraries:c_c++/hhdate)?
