By default, we group workspaces by monitor with the help of
_NET_DESKTOP_VIEWPORT. However, some users may experience this as an
unpredictable "shuffling" of workspaces. While WMs could disable
advertising the property itself, it seems more sensible to handle this
at the level of polybar. Hence, introduce a new group-by-monitor
flag—defaulting to true—which can be used to disable this behaviour.

* The xworkspaces module should wait for EWMH to become available
Before this change if EWMH wasn't available the xworkspaces module was
permanently disabled. When polybar was started alongside the window
manager e.g. from .xinitrc this caused a race condition between polybar
and the window manager and the xworkspaces module may or may not be
displayed. After this change polybar will wait for EWMH to become
available. This change closes#1915, see that issue for more details.
Curiously this only required the removal of the error condition which
used the be raised when EWMH wasn't available. The xworkspaces module
will show up on the bar as soon as the first EWMH event is processed by
the existing event handling code. I can't argue much about the
correctness of this patch but it seems to work flawlessly in my testing
with xmonad. I didn't test any other window managers. Note that removing
the error condition below which checks that _NET_DESKTOP_VIEWPORT is
available might make this work with pin-workspaces=true. I couldn't test
the effects of that change because I only tested with xmonad and xmonad
doesn't support _NET_DESKTOP_VIEWPORT, so I didn't make that change.
* xworkspaces: Remove check fo _NET_DESKTOP_VIEWPORT
Implementations that don't support it will just return an empty list for
get_desktop_viewports and pin-workspaces won't do anything.
* Update changelog
Fixes#1915

While it shouldn't happen with compliant WMs, it was possibe to crash
polybar with _NET_CURRENT_DESKTOP >= _NET_NUMBER_OF_DESKTOPS and this
should not be possible.
Includes polybar/xpp#31
Fixes#2398
* add reverse-scroll option for xworkspaces module
* move use of reverse-scroll option to when producing scroll action
* documented xworkspaces reverse-scroll option in changelog
* build: Add -Wsuggest-override
We should always use the override specifier when overriding virtual
functions. This helps prevent errors when a subclass tries to create a
function with the same name as a virtual function in a super-class but
with a different purpose.
* clang-format
* Upload logs on failure
* Add override to unsupported.hpp
* cmake: Make -Wsuggest-override flag conditional
* module: Implement proof of concept action router
Action implementation inside module becomes much cleaner because each
module just registers action names together with a callback (pointer to
member function) and the action router does the rest.
* Make input function final
This forces all modules to use the action router
* modules: Catch exceptions in action handlers
* Use action router for all modules
* Use action_ prefix for function names
The mpd module's 'stop' action overwrote the base module's stop function
which caused difficult to debug behavior.
To prevent this in the future we now prefix each function that is
responsible for an action with 'action_'
* Cleanup
* actions: Throw exception when re-registering action
Action names are unique inside modules. Unfortunately there is no way to
ensure this statically, the next best thing is to crash the module and
let the user know that this is a bug.
* Formatting
* actions: Ignore data for actions without data
This is the same behavior as before.
* action_router: Write tests
If two WM events arrive withing 25ms of one-another, the second one does
not trigger a bar update.
The module state is still correct, it is just not reflected in the bar.
This somehow caused updates being swallowed in fluxbox, but only after
PR #882 was merged, even though that 25ms restriction existed long
before that.
Fixes#2272
All modules now expose their actions as public static constants
Issues: The menu module no longer closes when an item is clicked (before
it would intercept any executed command and look if it matches one of
its exec commands)
This allows us to identify module by their type and it is also better to
store the module type as part of the module instead of having it
hardcoded in factory.hpp
A workspace is occupied if it is not active and there is at least one window managed by the WM (`_NET_CLIENT_LIST`) that has set `_NET_WM_DESKTOP` to that workspace.
The behavior when `_NET_WM_DESKTOP` is not set is not yet clear but this is unlikely to happen since most WMs will position windows on some desktop.
Closes#874Fixes#1444Fixes#1033
* Set Desktop OCCUPIED if a window moves there
This covers more of an edge-case. I did this first by accident, it might
vanish later on.
* Replace tracking change of WS with currently used WS
* Untrack occupied workspaces
* Track windows and their desktops in pairs
* Match type of occupied_desktops with current_desktop
Because the index needs to be matched later on, type mismatches would be non-ideal.
* Recreate the occupied desktops everytime and remove duplicates
* Readd support for moving windows to other desktops
* Use less characters to empty the vector
* Rename variable storing the desktops
* Recount windows on every occasion
This alone simplifies the management and the lookup for occupation of a
workspace
* Keep track of number of windows in every workspace
* Add debugging output that shall be removed before merging
* Remove obsolete TODO
* m_client_list should always be diff'd, since the desktop may change
Therefore we update the desktop-count tally every time the client_list
changes. It may just be a desktop-change without a change of
clients.size()...
* Add more logging-spam to understand window/desktop lifecycle
* Lock event-handler to serialize handling of events
* Fix occupied workspace counting and change to bool array
Also, performance improvements when diffing new and old client lists
* Fix crash when all clients are removed
* Conform to linter and styleguide
* Shorten conditional as it is standard enough
Since this only guards against 0-divisions, it can be shortened
without risking too much confusion down the road.
* Guard against multiple threads accessing and modifying data
Fixes#1444
Modification of internal data happens through the handle-method, while
the build-method tries to access the data structures for display. Since
some modifications clear e.g. the m_viewports, references may become
invalid between looping over them an accessing them.
The mutex should guard against this simultanuous access.
* Do not 'adopt_lock', because calls come from very different threads
To my understanding, adopt_lock has some dependency on the mutex-ownership. Since
the lock is once called from the inside (in handle) and once from the outside (in
build), there might be a problem. After brief testing, the segfaults happened fewer
times.
See #1444
* Also listen to _NET_WM_DESKTOP
In order to move a window from one desktop to another, it is sufficient
to set the desktop-property of that window. xmonad fires a lot of events
in the case of moving a window, herbstluftwm only updates the
_NET_WM_DESKTOP-atom of the window.
This change reloads the clientlist in order to correctly set the
desktop state "occupied".
* Describe need and use of mutex
It might be possible to relieve the guard in xworkspaces_module::handle,
but I am unsure about this. Since xmonad emits a lot of events on almost
every minor change, I would let the guard keep its post, avoiding
race-conditions in event-handling.
* Give temporary variables better names
* Clarify purpose of loop

* Remove merge-remainder
* Use a simpler method to list occupied desktops.
