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 ], ... }

Here's how you can define more helpers like the ones from this module:

-- some function you want to transform into an infix operator f :: a -> b -> Bool -- a new helper q ***? x = fmap (\a -> f a x) q -- or: (\b -> f x b) -- or q ***? x = fmap (`f` x) q -- or: (x `f`)

Any existing operator can be "lifted" in the same way:

q ++? x = fmap (++ x) q

# Documentation

Denotes a side of a screen. `S`

stands for South, `NE`

for Northeast
etc. `C`

stands for Center.

composeOne :: (Monoid a, Monad m) => [m (Maybe a)] -> m a Source #

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).

(-?>) :: (Functor m, Monad m) => m Bool -> m a -> m (Maybe a) infixr 0 Source #

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, Functor m) => m a -> a -> m Bool Source #

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

(^?) :: (Eq a, Functor m) => m [a] -> [a] -> m Bool Source #

q ^? x. if the result of `x `

, return True`isPrefixOf`

q

(~?) :: (Eq a, Functor m) => m [a] -> [a] -> m Bool Source #

q ~? x. if the result of `x `

, return True`isInfixOf`

q

($?) :: (Eq a, Functor m) => m [a] -> [a] -> m Bool Source #

q $? x. if the result of `x `

, return True`isSuffixOf`

q

(<==?) :: (Eq a, Functor m) => m a -> a -> m (Match a) Source #

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

(</=?) :: (Eq a, Functor m) => m a -> a -> m (Match a) Source #

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

(-->>) :: (Monoid b, Monad m) => m (Match a) -> (a -> m b) -> m b infixr 0 Source #

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.

(-?>>) :: (Functor m, Monad m) => m (Match a) -> (a -> m b) -> m (Maybe b) infixr 0 Source #

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 Source #

Return the current workspace

windowTag :: Query (Maybe WorkspaceId) Source #

Return the workspace tag of a window, if already managed

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

Helper to check if a window property contains certain value.

isKDETrayWindow :: Query Bool Source #

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

isFullscreen :: Query Bool Source #

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

.

isMinimized :: Query Bool Source #

A predicate to check whether a window is hidden (minimized). See also XMonad.Actions.Minimize.

pid :: Query (Maybe ProcessID) Source #

This function returns `Just`

the `_NET_WM_PID`

property for a
particular window if set, `Nothing`

otherwise.

See https://specifications.freedesktop.org/wm-spec/wm-spec-1.5.html#idm45623487788432.

transientTo :: Query (Maybe Window) Source #

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 :: (Monoid a, Functor m) => m (Maybe a) -> m a Source #

converts `MaybeManageHook`

s to `ManageHook`

s

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

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

transience :: MaybeManageHook Source #

A convenience `MaybeManageHook`

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

transience' :: ManageHook Source #

`transience`

set to a `ManageHook`

clientLeader :: Query (Maybe Window) Source #

This function returns `Just`

the `WM_CLIENT_LEADER`

property for a
particular window if set, `Nothing`

otherwise. Note that, generally,
the window ID returned from this property (by firefox, for example)
corresponds to an unmapped or unmanaged dummy window. For this to be
useful in most cases, it should be used together with `sameBy`

.

sameBy :: Eq prop => Query (Maybe prop) -> Query [Window] Source #

For a given window, `sameBy`

returns all windows that have a matching
property (e.g. those obtained from Queries of `clientLeader`

and `pid`

).

shiftToSame :: Eq prop => Query (Maybe prop) -> MaybeManageHook Source #

`MaybeManageHook`

that moves the window to the same workspace as the
first other window that has the same value of a given `Query`

. Useful
Queries for this include `clientLeader`

and `pid`

.

shiftToSame' :: Eq prop => Query (Maybe prop) -> ManageHook Source #

`shiftToSame`

set to a `ManageHook`

:: 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 Source #

Floats the window and makes it use the whole screen. Equivalent to

.`doRectFloat`

$ `RationalRect`

0 0 1 1

doCenterFloat :: ManageHook Source #

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

doSideFloat :: Side -> ManageHook Source #

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

doFloatAt :: Rational -> Rational -> ManageHook Source #

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 Source #

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

doHideIgnore :: ManageHook Source #

Hides window and ignores it.

doSink :: ManageHook Source #

Sinks a window

doLower :: ManageHook Source #

Lower an unmanaged window. Useful together with `doIgnore`

to lower
special windows that for some reason don't do it themselves.

doRaise :: ManageHook Source #

Raise an unmanaged window. Useful together with `doIgnore`

to raise
special windows that for some reason don't do it themselves.

doFocus :: ManageHook Source #

Focus a window (useful in `setActivateHook`

).
