Yuck is the new configuration syntax used by eww. While the syntax has changed dramatically, the general structure of the configuration has stayed mostly the same.
Most notably, the top-level blocks are now gone.
This means that defvar, defwidget, etc blocks no longer need to be in separate
sections of the file, but instead can be put wherever you need them.
Explaining the exact syntax of yuck would be significantly less effective than just looking at an example, as the general syntax is very simple.
Thus, to get a feel for yuck, read through the example configuration.
Additionally, a couple smaller things have been changed.
The fields and structure of the defwindow block as been adjusted to better reflect
the options provided by the displayserver that is being used.
The major changes are:
- The
screenfield is now calledmonitor reserveandgeometryare now structured slightly differently (see here) To see how exactly the configuration now looks, check the respective documentation
A couple amazing people have started to work on an automatic converter that can turn your old eww.xml into the new yuck format!
