XMonad.Hooks.ManageHelpers

Description

This module provides helper functions to be used in `manageHook`. Here's how you might use this:

    import XMonad.Hooks.ManageHelpers
    main =
        xmonad def{
            ...
            manageHook = composeOne [
                isKDETrayWindow -?> doIgnore,
                transience,
                isFullscreen -?> doFullFloat,
                resource =? "stalonetray" -?> doIgnore
            ],
            ...
        }

# Documentation

data Side #

Denotes a side of a screen. `S` stands for South, `NE` for Northeast etc. `C` stands for Center.

composeOne :: [MaybeManageHook] -> ManageHook #

An alternative `ManageHook` composer. Unlike `composeAll` it stops as soon as a candidate returns a `Just` value, effectively running only the first match (whereas `composeAll` continues and executes all matching rules).

(-?>) :: Query Bool -> ManageHook -> MaybeManageHook infixr 0 #

A helper operator for use in `composeOne`. It takes a condition and an action; if the condition fails, it returns `Nothing` from the `Query` so `composeOne` will go on and try the next rule.

(/=?) :: Eq a => Query a -> a -> Query Bool #

q /=? x. if the result of q equals x, return False

(<==?) :: Eq a => Query a -> a -> Query (Match a) #

q <==? x. if the result of q equals x, return True grouped with q

(</=?) :: Eq a => Query a -> a -> Query (Match a) #

q </=? x. if the result of q notequals x, return True grouped with q

(-->>) :: Query (Match a) -> (a -> ManageHook) -> ManageHook infixr 0 #

A helper operator for use in `composeAll`. It takes a condition and a function taking a grouped datum to action. If `p` is true, it executes the resulting action.

(-?>>) :: Query (Match a) -> (a -> ManageHook) -> MaybeManageHook infixr 0 #

A helper operator for use in `composeOne`. It takes a condition and a function taking a groupdatum to action. If `p` is true, it executes the resulting action. If it fails, it returns `Nothing` from the `Query` so `composeOne` will go on and try the next rule.

currentWs :: Query WorkspaceId #

Return the current workspace

isInProperty :: String -> String -> Query Bool #

Helper to check if a window property contains certain value.

isKDETrayWindow :: Query Bool #

A predicate to check whether a window is a KDE system tray icon.

isFullscreen :: Query Bool #

A predicate to check whether a window wants to fill the whole screen. See also `doFullFloat`.

isDialog :: Query Bool #

A predicate to check whether a window is a dialog.

pid :: Query (Maybe ProcessID) #

transientTo :: Query (Maybe Window) #

A predicate to check whether a window is Transient. It holds the result which might be the window it is transient to or it might be `Nothing`.

maybeToDefinite :: MaybeManageHook -> ManageHook #

converts `MaybeManageHook`s to `ManageHook`s

type MaybeManageHook = Query (Maybe (Endo WindowSet)) #

A ManageHook that may or may not have been executed; the outcome is embedded in the Maybe

transience :: MaybeManageHook #

A convenience `MaybeManageHook` that will check to see if a window is transient, and then move it to its parent.

transience' :: ManageHook #

`transience` set to a `ManageHook`

doRectFloat #

Arguments

:: RationalRect | The rectangle to float the window in. 0 to 1; x, y, w, h.
-> ManageHook |

Floats the new window in the given rectangle.

doFullFloat :: ManageHook #

Floats the window and makes it use the whole screen. Equivalent to ``doRectFloat` $ `RationalRect` 0 0 1 1`.

doCenterFloat :: ManageHook #

Floats a new window with its original size, but centered.

doSideFloat :: Side -> ManageHook #

Floats a new window with its original size on the specified side of a screen

doFloatAt :: Rational -> Rational -> ManageHook #

Floats a new window with its original size, and its top left corner at a specific point on the screen (both coordinates should be in the range 0 to 1).

doFloatDep :: (RationalRect -> RationalRect) -> ManageHook #

Floats a new window using a rectangle computed as a function of the rectangle that it would have used by default.

doHideIgnore :: ManageHook #

Hides window and ignores it.

data Match a #

A grouping type, which can hold the outcome of a predicate Query. This is analogous to group types in regular expressions. TODO: create a better API for aggregating multiple Matches logically
