Dear All, Summary: ======== I think withWorkspace, from Actions.DynamicWorkspaces, does not honor fuzzyMatch (Prompt.FuzzyMatch). In contrast, selectWorkspace and renameWorkspace (also from DynamicWorkspaces) do work with fuzzyMatch. workspacePrompt (Prompt.Workspace) and switchProjectPrompt (Actions.DynamicProjects) also work with fuzzyMatch. Details ======== With this in my xmonad.hs mySPcentered = def { searchPredicate = fuzzyMatch , sorter = fuzzySort } the following , ("M-m", withWorkspace mySPcentered (windows . W.shift)) does not use fuzzy matching but , ("M-m", workspacePrompt mySPcentered (windows . W.shift)) does use fuzzy matching. Note that , ("M-a", selectWorkspace mySPcentered) , ("M-s", renameWorkspace mySPcentered) both use fuzzy matching (and both selectWorkspace and renameWorkspace are from DynamicWorkspaces). And note that , ("M-w", switchProjectPrompt myProjectConfig) with switchProjectPrompt from Actions.DynamicProjects, also works with fuzzyMatch. Workaround? =========== Complete Haskell ignorant here, but from looking at the source of withWorkspace (Actions.DynamicWorkspaces) and workspacePrompt (Prompt.Workspace), I wonder if withWorkspace should be written as withWorkspace c job = do ws <- gets (workspaces . windowset) sort <- getSortByIndex let ts = map W.tag $ sort ws job' t | t `elem` ts = job t | otherwise = addHiddenWorkspace t >> job t mkXPrompt (Wor "") c (mkComplFunFromList' c ts) job' I have changed the last line from mkXPrompt (Wor "") c (mkCompl ts) job' to mkXPrompt (Wor "") c (mkComplFunFromList' c ts) job' Using this in my xmonad.hs seems to work fine with windows' shift, copy and shiftThenView (last one from Ivan Malison's https://github.com/ivanmalison/dotfiles/blob/0a84ad772e21155cfc00458b66ccb79...)
