Hi all, I don't know why but suddenly, xmonad decided to recompile itself and I got warnings : Deprecations detected while compiling xmonad config: /home/alain/.xmonad/xmonad.hs $ ghc --make xmonad.hs -i -ilib -fforce-recomp -main-is main -v0 -outputdir /home/alain/.xmonad/build-x86_64-linux -o /home/alain/.xmonad/xmonad-x86_64-linux xmonad.hs:16:1: warning: [-Wtabs] Tab character found here, and in one further location. Suggested fix: Please use spaces instead. | 16 | spawnOn "bg" "feh --bg-tile /usr/share/WindowMaker/Backgrounds/BlueImage.jpeg" | ^^^^^^^^ xmonad.hs:35:30: warning: [-Wdeprecations] In the use of ‘defaultConfig’ (imported from XMonad, but defined in XMonad.Config): Deprecated: "Use def (from Data.Default, and re-exported by XMonad and XMonad.Config) instead." | 35 | , manageHook=manageHook defaultConfig <+> manageDocks | ^^^^^^^^^^^^^ I don't find the tab character, if I delete what appears to me as a space, then type a space, I have another error message. How should I replace "defaultConfig" ? Thanks for your help.
