This page is for keeping a record of significant changes in darcs xmonad and xmonad-contrib since the 0.8.* releases. See 'darcs changes' for more details about miscellaneous feature enhancements, and documentation and bug fixes not noted here.

(0.8.1 was a maintenance release, with no changes to user functionality. It simply includes ghc-6.10.1 related updates and a ghc optimization bug workaround for 64-bit users building xmonad-contrib on ghc-6.10.1.)

The idea is to put here a list of things which a user upgrading from 0.8 to 0.9 might like to know, so that they are sure to be included in the 0.9 release notes.

See also, the haddock documentation for darcs modules mentioned here.

Updates that require changes in xmonad.hs

Modules formerly using Hooks.EventHook now use Event from core. Note: EwmhDesktops users must change configuration by adding a handleEventHook to XConfig. (No need to change config if using ewmh via Config.Desktop, Config.Gnome, etc.)

Most DynamicLog users can continue with configs unchanged, but users of the quickbar functions xmobar or dzen will need to change xmonad.hs: their types have changed to allow easier composition with other XConfig modifiers. The dynamicLogDzen and dynamicLogXmobar functions have been removed.

People who explicitly use swapMaster in key or mouse bindings should change it to shiftMaster. It's the current default used where swapMaster had been used previously. It works better than swapMaster when using floating and tiled windows together on the same workspace.

Scratchpad workspace is now "NSP" which is also used by the new Util.NamedScratchpad.

WindowGo or safeSpawn users may need to change command lines due to safeSpawn changes.

Changes to the xmonad core

  • Supports using local modules in xmonad.hs For example: to use definitions from ~/.xmonad/lib/XMonad/Etc/Foo.hs
    • import XMonad.Etc.Foo
  • Spawned processes are now handled by xmonad. Using 'exec xmonad' in startup files now "does the right thing."
  • New --restart command line flag to restart a running xmonad process.
  • Focus changes across screens with mouse movement, no longer requiring a click, even for empty workspaces. (With focus follows mouse enabled).
  • XMonad now exports (.|.), no need to import Data.Bits.
  • StackSet exports focusUp', focusDown' for Stack in addition to focusUp/Down StackSet versions.
  • XConfig has new handleEventHook:: Event -> X All field supporting custom event hooks. The function should return (All True) to have the default handler run afterward. (See Graphics.X11.Xlib.Extras Event, Core.hs, Main.hs)
  • X is now typeable. (Enables Language.Haskell.Interpreter, i.e. hint integration, see xmonad-eval project below.)

Changes to xmonad-contrib

Updated modules

Actions

  • Actions.CopyWindow has new runOrCopy
  • Actions.CycleWS now includes HiddenWS type.
  • Actions.Plane has a planeKeys function to automatically set up default spatial workspace navigation.
  • Actions.Search has more searches.
  • Actions.Submap now supports a default action, enabling looping to, e.g., set volume, or use an explicit 'exit submap' key.
  • Actions.WindowBringer now works with external programs other than dmenu, such as nafai's gtkmenu
  • Actions.WindowGo
    • has raiseMaster variant of runOrRaiseMaster
    • uses safeSpawn instead of regular spawn

Config

  • All desktop configs now set the root window mouse cursor when xmonad starts up. (Desktop, Gnome, Kde, Xfce)
  • Config.Gnome also registers with dbus for speedier startup on many Gnome setups.
  • Config.Kde has optional KDE 4 specific settings.

Hooks

  • Hooks.EwmhDesktops requires new handleEventHook = ewmhDesktopsEventHook be added to non-desktop configs (like defaultConfig).
  • Hooks.DynamicLog module has a new 'statusBar' function to simplify status bar configuration. Similar dzen and xmobar quick bar functions have changed type for easier composition with other XConfig modifiers. dynamicLogDzen and dynamicLogXmobar have been removed. Format stripping functions for xmobar and dzen have been added to allow independent formatting for ppHidden and ppUrgent. (They will hopefully be made obsolete by 0.9 release.)
  • Hooks.FadeInactive -- Fade parameter can now be a rational between 0 and 1 or an old style 0xffffffff based value. The module interface is more powerful and flexible.
  • Hooks.ManageDocks' Direction type was renamed to Direction2D and is now defined in XMonad.Util.Types. This requires configs that use Direction in type signatures or imports to use Direction2D instead. Has a new SetStruts message in addition to the current toggle.
  • Hooks.ManageHelpers has new 'doFloatDep' and 'doFloatAt' to add more control over floating window geometry.
  • Hooks.RestoreMinimized provides an event hook to restore minimized windows from taskbars. (see Layout.Minimize)
  • Hooks.UrgencyHook now can be configured with reminders at intervals, and urgency can be cleared with a keybinding even without "visiting" the urgent window.
  • Hooks.ServerMode has a better interface for having xmonad execute custom commands specified by user via root window property events.

Layout

  • Layout.Grid Grid defaults to 16/9, plus offers new GridRatio with configurable aspect ratio.
  • Layout.LayoutHints layoutHintsToCenter added, to respect size hints but eliminate gaps between windows by placing them at outside edges.
  • Layout.Master is now a layout modifier rather than layout. Also, it no longer applies size hints by default; otherwise it's backward compatible with old Master.
  • Layout.Maximize maximizes to a slightly larger window size than previously. When maximizing a new window it automatically restores the previously maximized one. It also moves maximized windows to the background when not focused.
  • Layout.ThreeColumns has several new features including placing master at center.

Prompt

  • Prompt keymaps are now customizable via XPConfigs. Prompt configs include a history filter field and deleteConsecutive and deleteAllDuplicates functions for easier history usage with Prompt modules.
  • Prompt.Search completions only use search history, rather than old behavior of matching any prompt's entries.

Util

  • Util.EZConfig includes <Print>, and on systems with X11 that supports them, multimedia keys.
  • Util.Loggers has several new loggers and logger formatting utilities.
  • Util.Run's "safeSpawn" has changed types; now it takes a list of strings/arguments, instead of a single string.
  • Util.Scratchpad has general spawn action allowing user to specify how to set resource to "scratchpad", allows use of gnome-terminal, etc. as scratchpads. Also new NamedScratchpad module now allows multiple summon/banishable applications.
  • Util.Themes has many more themes to try out with tabbed and other decorated layouts
  • Util.WindowProperties has general getProp32* helpers and doc improvements
  • Util.XSelection has new functions to allow transforming the selection before acting on it.

etc

  • Config.Kde has optional KDE 4 specific settings.
  • XMonad.Prompt has more tab completion settings, configurable history filter, several bug fixes.
  • UTF-8 handling has been improved throughout core and contrib.

New contrib modules

Actions

  • Actions.BorderResize -- resize windows by dragging their borders with the mouse (for layouts that react to SetGeometry, i.e. mostly floating layouts.)
  • Actions.CycleWindows -- Cycle recent windows, cycle custom window order, focus nth window, change focused or unfocused window order. Esp. useful with layouts that hide some windows.
  • Actions.FloatSnap -- Tools for moving and resizing floating windows with configurable snapping to various window edges. See also Hooks.Place.
  • Actions.GridSelect -- Graphically go to, select, do things with windows. Since its first release it's gained additional colourizers, customizable keybindings plus mouse support. It's also been generalized to work with more than just windows, use to select workspaces, applications to spawn, prompts, etc.
  • Actions.MessageFeedback -- Provides a version of sendMessage that returns an X Bool reflecting whether or not the Message was handled. Allows specifying alternative Messages to be sent in sequence until one is handled.
  • Actions.OnScreen -- Functions for use with multiple screens to control workspaces on unfocused screens.
  • Actions.PhysicalScreens -- More intuitive use of multiple xinerama screens by physical ordering rather than ScreenID. (I.e. no more rebinding mod-{w,e,r} because xorg chose 0:middle, 1:right, 2:left, etc.)
  • Actions.RandomBackground -- Start terminals with random '-bg' color or generate random hex color strings. The range of colors can be restricted using RGB min/max value or HSV saturation and value.
  • Actions.SpawnOn -- Binding actions, hooks, and prompts to spawn on given or current workspace.
  • Actions.TopicSpace -- Utilities for task oriented workspaces: set working directory, startup actions when no windows are on the space, display and navigate topic workspaces by history of last focused topics.
  • Actions.UpdateFocus -- When switching workspaces and using focus follows mouse ensure the window under the mouse is focused as soon as it moves a bit.
  • Actions.WindowMenu -- Provides a GridSelect menu for selecting window commands such as minimize, shift to workspace, etc.
  • Actions.WorkspaceCursors -- navigate workspaces in arbitrary number of dimensions. For example, use nine 3 x 3 grids of workspaces, binding keys to navigate in each of those three dimensions.
  • Actions.WithAll -- Apply functions to all windows on a workspace.

Hooks

  • Hooks.FloatNext -- No need to mess with DynamicHooks if you want to float next windows; use this instead!
  • Hooks.Place -- Manage floating windows in just about any conceivable manner. Very neat module for floating window users. Also see Actions.FloatSnap.
  • Hooks.InsertPosition -- Ready made options for position and focus of new windows, e.g 'insertPosition Master Newer' to insert at master and focus it, 'insertPosition Above Older', etc.
  • Hooks.WorkspaceByPos -- For multi-head setups, when windows request geometry not on the current screen attempt to honor it as much as possible by moving the window to the requested screen.

Layout

  • Layout.AutoMaster -- Modifies a base layout used in slave area by adding a horizontal master area above it (like Mirror Mastered). The master area shrinks to make more room for slaves as more slave windows are created, but can also manually shrink expand and increment or decrement number of masters as normal.
  • Layout.CenteredMaster -- Sort of a combination of Master's mastered modifier with Magnifier, adding a master frame above tiled windows that is centered or at the top right of the screen.
  • Layout.Cross -- Similar to Circle, but with a resizable center pane. Limits visible windows to five. Cycles the focused window into the main window keeping visible two above and two below in stack order.
  • Layout.Column -- Arrange windows in a column with heights forming a geometric progression: h1/h2 = h2/h3 = ... = q where q is adjustable via Shrink/Expand.
  • Layout.ComboP -- Combine layouts more usefully than plain L.Combo: use window properties to decide which windows go to which layout, and move or swap windows between layouts.
  • Layout.FixedColumn -- Neat variation on Tall, using window hints to decide master width, e.g. have your terminal automatically be 80 columns wide in the master.
  • Layout.GridVariants -- More customizable Grid, and adjustable SplitGrid, for details see here.
  • Layout.IndependentScreens -- Utilities to simulate dwm's screen model, where each physical screen has its own set of the defined workspaces.
  • Layout.LayoutBuilder -- another method for combining layouts based on number of windows to place into different sub screen layouts.
  • Layout.LimitWindows -- modify a layout to limit the number of visible windows. The number visible can be raised or lowered via keybindings.
  • Layout.MessageControl -- tools for piping messages to the correct sub layout in complex combined layouts.
  • Layout.Minimize -- layout modifier to minimize windows (see also Hooks.RestoreMinimized)
  • Layout.Monitor -- Many useful functions for gkrellm, clock, widget type windows.
  • Layout.MouseResizableTall -- ResizableTall-like layout where tiles can be resized with the mouse. All window separations can be dragged to modify the layout. Key bindings can also be used.
  • Layout.NoFrillsDecoration -- basic decoration (title bars) for windows even simpler than SimpleDecoration.
  • Layout.OneBig -- A little like Mosaic combined with Grid, this layout lets you specify a (top left) master area as fractions of screen dimension, (yes, can shrink/expand it), then it splits the rectangles below and to the right of that area into equal portions.
  • Layout.SubLayouts -- much requested tools to nest layouts in other layouts.
  • Layout.Spacing -- puts blank space around each window.
  • Layout.Mosaic -- Versatile, easy to configure, fun layout that can yield a wide range of layouts. It sizes panes based on the relative sizes of a list of numbers. Keybindings can be added to resize windows and change the overall aspect ratio.

Util

  • Util.SetCursor allows setting the root window cursor from xmonad rather than in .xsession, .xinitrc, etc. It is included in the startupHook when using desktop configs instead of defaultConfig for the base config.
  • Util.Paste -- For pasting strings to windows.
  • Util.NamedActions -- Make keybindings showable.
  • Util.NamedScratchpad -- Allows multiple summon/banishable application windows each with its own float configuration.
  • Util.Replace -- Configure xmonad to replace compliant window managers started from sessions such as metacity so for example one can work in metacity for a while, then start xmonad.
  • Util.StringProp -- Internal utility functions for storing Strings with the root window. Used for global state like IORefs with string keys that persists over xmonad restarts. However, this persistence comes at the cost of more latency and increased traffic with the X server.
  • Util.Types -- Unifies Direction types used in various modules. Dev utility.

Deleted modules

  • Config.PlainConfig is now a separate project, shepheb's xmonad-light.
  • Hooks.EventHook is superseded by handleEventHook from core.

Related Projects

xmonad-light allows using a limited version of xmonad without having to have ghc installed. It provides a special syntax to customize a few common options using xmonad.conf instead of xmonad.hs.

xmonad-extras includes some modules with additional dependencies, like a Volume control, an MPD prompt and a module that uses the hint interpreter to manipulate xmonad state during runtime via normal haskell expressions ala emacs eval.

xmonad log applet allows displaying xmonad logHook output in gnome-panel.

dzen-utils provides combinators for creating and processing dzen2 input strings.

For users of >=ghc-6.10, the hlint package parses haskell source and offers suggestions on how to improve it.
