This adds the 'send' action to the ipc module that can be used to send arbitrary text to the module:
polybar-msg action "#ipc.send.%{F#4444ff}hello%{F-}"
* feat(ipc): allow receiving arbitrary text on IPC socket
Instead of just allowing hook numbers to be executed, the user can
send arbitrary text and the IPC module will put it in the bar. The IPC
payload format is extended to accept an arbitrary string if the first
character after the module name is ':'.
polybar-msg hook test :'%{F#4444ff}hello%{F-}'
Fix#2455
* Use actions for sending data to ipc module
* ipc: Don't use exceptions when no hooks are defined
* Update src/modules/ipc.cpp

* Add toggle_visible action
* Add set_visible and set_invisible actions
* Rename toggle_visible method to match
`action_toggle_visible` -> `action_toggle_visibility`
Matches with `EVENT_TOGGLE_VISIBILITY`
* Update CHANGELOG
* Revert #2320 IPC commands
IPC commands are no longer necessary now that the actions are
implemented. Changed some method permissions as well to reflect this.
* Add logging and change action names
- `module_toggle`
- `module_show`
- `module_hide`
Delineate common actions to all modules with a `module_` prefix (for
future actions too)
* Update documentation
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
When `pin-workspaces` is set to true using `show-urgent` will show
urgent workspaces on the bar even when the workspace is not associated
with the current monitor.
* 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
Modules can now also be shown and hidden using ipc commands:
$ polybar-msg [-p PID] cmd hide.mymodule # Hides module mymodule
$ polybar-msg [-p PID] cmd show.mymodule # Shows module mymodule
$ polybar-msg [-p PID] cmd toggle.mymodule # Toggles visibility of mymodule
* Hopefully implement visibility checking
* Implement hide command
* Implement `show` and `toggle` commands
* Refactor and add some logging
* Run style checks and update CHANGELOG
* Get around unused parameter warnings
* Change `set_visible` to return nothing
* Make errors more informative

* refactor(color): Use enum class for color type
* Add testcases for tag parser
* Make tag parser a pull-style parser
Being able to parse single elements at a time gives us more fine-grained
error messages, we can also parse as much as possible and only stop
after an exception.
* fix(color): Parser did not check for invalid chars
* tag parser: First full implementation
* tag parser: Fix remaining failing tests
* tag parser: Replace old parser
* tag parser: Treat alignment as formatting tag
Makes the structure less complex and the alignment tags really are
formatting tags, they are structurally no different from the %{R} tag.
* tag parser: Cleanup type definitions
All type definitions for tags now live in tags/types.hpp, the parser.hpp
only contains the definitions necessary for actually calling the parser,
this shouldn't be included in many places (only places that actually do
parsing). But many places need the definitions for the tags themselves.
* Rename components/parser to tags/dispatch
* tag parser: Cleanup
* Add changelog
The change in #2270 accidentally broke how we access module types.
module<Impl>::TYPE always points to the module superclass and it thus
accesses its empty TYPE field.
This mainly broke legacy action handling.
Ref #2270
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
Since 3.5.0, we use m_interval for a modulo operation, this crashes the
bar if the interval is 0. A non-positive interval shouldn't be allowed
anyway, so we now throw an exception in that case.
Fixes#2273
* [Temperature, Ramp] fix wrong icon for temperatures near base and warn temps
* [Temperature, Ramp] fix wrong icon for temperatures near base and warn temps
* Fix minor error
* Added WARN state for cpu module
* Implement WARN state for CPU, Memory modules, working on fs module
* Implement WARN state for fs module
* Simplify WARN state implementation for cpu and memory
* explicitly check percentage in get_by_percentage_with_borders
* Fixed silly error
* implement warn state on battery module, standardize the implementation on other modules
* minor fixes
* fix annoying error
* use more intuitive param name
* Fix percentage with borders bug
* Make requested changes
Hide the effect of warn states when unused
* Backward Compat: use no format instead of fallback label
* Reformat
* Refactor
* Reformat
* Reformat: convert tabs to spaces
* Reformat
New config option `speed-unit = B/s` will be used to suffix the upload and download speeds.
* mod::network: udspeed-unit to set network speed unit suffix
* Changed udspeed-unit to speed-unit
Only modules can now be action handlers.
This also slightly simplifies the controller because we don't need to
keep track of input handlers, we can just use the module list.
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
Action strings now have the form '#MODULE#ACTION'
For example to trigger the action 'toggle' in the 'module/date' module
one would now use '%{A1:#date#toggle:}'
With this action strings can now be uniquely assigned to one module.
Fixes#1172
Any timer_module based module would sleep for the set interval and then
continue running. Depending on the start time of polybar this
sleep pattern might not be aligned, which causes such modules to always
update in a shifted manner.
Consider the date module as an example. If the update interval is set to
60 seconds and polybar was started at 13:37:37, polybar would update the
clock at 13:38:37, 13:39:37 and so on.
To make matters worse, if a module would perform lengthy checks this
interval might drift over time, causing even more inconsistent updating.
This patch extends the base module with a sleep_until method that calls
the corresponding function on the sleephandler. Additionally the
timer_module is extended to compute the remaining time until the next
interval passes and sleep accordingly.
Closes#2064

A warning implies something went wrong and (possibly) the user should do
something about it. However, warnings are not always used this way.
For example:
* When a fallback value for a `${..}` reference is used, this shouldn't
produce a warning (or notice) since using fallbacks is not something
bad.
* pulse telling you that it uses the default sink because no sink was
specified also does not warrant a warning (even notice may be too
high).
* Whenever polybar shuts down it produces a "Termination signal
received..." warning. Since there isn't a more proper way to shut down
polybar, it should not produce a warning. Same argument for a
`screenchange-reload`
The github module only authenticate by query string, and this method is deprecated:
https://developer.github.com/changes/2019-11-05-deprecated-passwords-and-authorizations-api/#authenticating-using-query-parameters
There is no reason to remove it before the method stop working, so I've made possible to the user choose which authentication method he will use:
* The parameter token remain unchanged.
* If the parameter user is passed then the module will use the not deprecated method, passing user and token on the body of the requisition. Otherwise the module will use the deprecated method.

Fixes#2002
Adds `format-offline` and `label-offline`
* feat(github): offline label & fixes
* Clear label if there are no notifications and empty-notifications = false
* clang-format

None of the payload fields seem to be used. They were the only place
where EVENT_SIZE was used and why it had to be a macro (no variable
length arrays).
Some people use text modules instead of the `separator` key in the bar
section to better configure the separator (colors, fonts).
Since we disallowed the same module being used multiple times in #1534,
this will now print an error message.
This should help with this a bit.
Ref #1913
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
About 80% of this comment are taken from
https://github.com/jaagr/polybar/pull/882#discussion_r255317363
* Remove merge-remainder
* Use a simpler method to list occupied desktops.
