- tasks for xmonad 0.2
- fix the numlock issue once and for all
- think about the statusbar/multithreading.
Three shared TVars:
windowTitle :: TVar String
workspace :: TVar Int
statusText :: TVar String
Three threads:
Main thread, handles all of the events that it handles now. When
necessary, it writes to workspace or windowTitle
Status IO thread, the algorithm is something like this:
forever $ do
s <- getLine
atomic (writeTVar statusText s)
Statusbar drawing thread, waits for changes in all three TVars, and
redraws whenever it finds a change.
- Notes on new StackSet:
The actors: screens, workspaces, windows
Invariants:
- There is exactly one screen in focus at any given time.
- A screen views exactly one workspace.
- A workspace is visible on one or zero screens.
- A workspace has zero or more windows.
- A workspace has either one or zero windows in focus. Zero if the
workspace has no windows, one in all other cases.
- A window is a member of only one workspace.
