X.L.LayoutBuilderP is nearly identical to X.L.LayoutBuilder. Originally
I wanted to add the ability to dynamically resize the layout boxes so it
make a lot of sense to join these two modules together so I wouldn't
have to do it in both. Even though I never got around to that I still
think it's a good idea to merge these two modules into one.
I believe I was able to merge these without creating any
backward-compatibility issues. I've been sitting on these changes since
2015 and they work for me without having to change older parts of my
config (relating to X.L.LayoutBuilder).
If anyone wants to work on dynamically resizing layout boxes the issue I
created for it is #36.
This better expresses the idea that the argument to alwaysTrue is just there to
select an instance. Another option could be to do use a fundep, which seems to
be compatible with the two instances so far.
class Predicate p w | p -> w
LayoutBuilderP is similar to LayoutBuilder (and is based on it), but LayoutBuilderP places windows matching given X.U.WindowProperties.Property (or any other predicate) into one rectangle, instead of fixed number of windows.
