None of these properties are currently being set when xmonad starts:
_NET_ACTIVE_WINDOW(WINDOW): window id # 0x0
_NET_CURRENT_DESKTOP(CARDINAL) = 0
_NET_CLIENT_LIST_STACKING(WINDOW): window id #
_NET_CLIENT_LIST(WINDOW): window id #
because the caching introduced in 92fe5f34ff initializes the
cache with the same values that they should have in an empty session, so
we don't detect a change and don't set them.
Fix it by initializing the cache with impossible (or at least extremely
improbable) values.

This enables adding the Typeable constraint to LayoutClass itself
(https://github.com/xmonad/xmonad/pull/242) which in turn enables
querying the current layout state. That might be useful to e.g. show the
current X.L.WorkspaceDir in xmobar.
This is a preparation commit that fixes the compile failures that would
result in merging that change to xmonad. For this to be generally useful
we first need to merge (and ideally also release) that xmonad change,
and then we'll need some documentation and perhaps a type class to help
find the right LayoutModifier in the tree of ModifiedLayouts and
Choices. That will come later.
This makes it possible to change the workspace directory by sending a
message, which enables automation/scripting not possible with
`changeDir` which displays a prompt.
Example of such usage:
6ea6c52aac/.xmonad/xmonad.hs (L183-L189)
- By default window activation does nothing.
- `activateLogHook` may be used for running some 'ManageHook' for
activated window.
- `activated` predicate may be used for checking was window activated or
not.
This module contains a modifier that simply sets X11 window border width
to 0 for every window in the layout it modifies. No efforts are made to
bring the border back, which can be annoying if windows are moved to a
different workspace, but it prevents the "border flash" you get with
XMonad.Layout.NoBorders.
Configs that apply WorkspaceId transformations, such as
IndependentScreens (adding/removing a screen-number prefix) and
NamedWorkspaces (adding/removing a name suffix), cannot use clickablePP
as is, since they need to apply clickableWrap to an appropriately
transformed WorkspaceId. Rather than force them to reimpliment
clickableWrap, export it.
An example use-case, where IndependentScreens has added a screen number
prefix to the workspace ids (0_1, 0_2, ...), and we want a status-bar
that shows the ids without screen number (1, 2, ...), but also makes
them clickable:
getClickable :: (WorkspaceId -> WorkspaceId) -> X (WorkspaceId -> String)
getClickable f = do
wsIndex <- getWsIndex
pure $ \ws -> case wsIndex (f ws) of
Just idx -> clickableWrap idx ws
Nothing -> ws
composePP :: PP -> ScreenId -> X PP
composePP pp s = do
clickable <- getClickable (marshall s)
return
. marshallPP s
$ pp
{ ppCurrent = ppCurrent pp . clickable,
ppVisible = ppVisible pp . clickable,
ppHidden = ppHidden pp . clickable,
ppHiddenNoWindows = ppHiddenNoWindows pp . clickable,
ppUrgent = ppUrgent pp . clickable
}
Parameterizing completion case-sensitivity for single-mode prompts was
possible without making any breaking changes. For multi-mode prompts,
however, the completion function is expressed through the XPrompt
'completionFunction' method. The only argument that method receives is a
Dir value, so parameterizing completion case-sensitivity means adding a
new field to the Dir constructor.
Provide a way to perform case-insensitive file / directory completion.
We're using compgen to generate completion candidates, and this is
case-sensitive by default. We can control this by setting the
completion-ignore-case Readline variable prior to invoking compgen. If
we're running a Bash with Readline support, this works as expected.
Otherwise, it has no effect -- completion candidates are still returned,
but compgen generates them in a case-sensitive manner.
To avoid breaking changes, the signatures and behavior of existing
exported functions are unchanged:
- XMonad.Layout.WorkspaceDir.changeDir
- XMonad.Prompt.Directory.directoryPrompt
- XMonad.Prompt.Shell.getShellCompl
New variations of these functions are provided, allowing the caller
to specify the desired case-sensitivity via a ComplCaseSensitivity
argument:
- XMonad.Layout.WorkspaceDir.changeDir'
- XMonad.Prompt.Directory.directoryPrompt'
- XMonad.Prompt.Shell.getShellCompl'
The XMonad.Prompt.Shell exports a couple new functions:
- compgenDirectories
- compgenFiles
We make use of this in XMonad.Prompt.Directory to avoid duplicating the
compgen code.
Add an example and more comments to the documentation, and make some
small code tweaks (more type signatures and a couple variable renames)
to aid readability.
Add a statusBar' function that accepts pretty printing options embedded
in the X monad, so users can leverage dynamic printing modifiers, such
as workspaceNamesPP.
