Avoids a race where the pipe could be inherited by another process
spawning at about the same time. If the other process didn't exit
quickly (e.g. if it was a custom script that did its own looping), it
would keep the write end of the pipe open, and so reading from the pipe
to try to get the command's output would block.
This bug manifested as some custom modules randomly not appearing in the
bar, requiring a reload to fix. The custom script had run and exited,
but the pipe had been inherited by another process, and the thread that
updated the module's output was blocked trying to read from it.
some users (maybe only myself) may want to sort the task bar by app_id
which then places occurrences of the same task next to each other.

In order to fix the issue, the default node name is cached rather than
the default node id. This is due to ids being unstable. So now when the
object manager is installed (ie ready), the default node name is
retrieved and stored for later.
Now when the mixer changed signal is emitted, the id of the changed node
is used to get the node from the object manager. The nodes name is
grabbed off that node and compared against the default node name, if
they match the volume is updated. Some safeguarding has been added such
that if the node cannot be found off the object manager, it's ignored.
Additionally, the "changed" signal on the default nodes api is now
utilized to update the default node name if it has changed. This way if
the default node changes, the module will be updated with the correct
volume and node.nick.
This adds additional debug logging for helping diagnose wireplumber
issues.
This also adds the wireplumber man page entry to the main waybar
supported section.
Provides CSS classes empty, floating, tabbed, tiled, solo, stacked and
app_id.
Adds offscreen-css bool option (default false), only effective when
"all-outputs" is true. This adds styles on outputs without focused
node, according to its focused workspaces window situation.
Adds an "offscreen-css-text" string option (default empty), only
effective when "all-outputs" and "offscreen-style" are set. This
is shown as a text on outputs without a focused node.
Adds a "show-focused-workspace" bool option (default false) to indicate
the workspace name if the whole workspace is focused when nodes are
also present. If not set, empty text is shown, but css classes
according to nodes in the workspace are still applied.
Limitation:
When the top level layout changes, there is no sway event so the
module cannot react. Perhaps in the future recurring polling can
be added to go around this limitation.
1. Calendar. Weeks. Fix right paddings when first days of the week is
Monday
2. Fix small perfomrance penalty(avoid of defining parameter in the
month loop)
3. Small name convention for format string variables
1. Let's do code simplier
2. Week format using regexp. Needs when user provide additional
characters in format string and need to align week days according
3. Week format has got default formats: ":%U",":%V"
4. Week number is based on the first day of the week now. The output is
the same as of date library now.
5. Avoiding of unnecessary operations
The first crash occurs when trying to parse the
ID of a workspace as an uint, since named
workspaces has negative IDs. This is fixed by
using ints for workspace IDs instead of uints.
The second crash occurs when converting a
workspace name that isn't a number to an integer.
This is fixed by wrapping std::stoi in a try
block and only sorting by number, when both names
can successfully be converted to integers.
Adds basic support for showing volume via wireplumber. Allows specifying
the node-id or falling back to the default Audio/Sink node id if node-id
is not set. If tooltip on hover is enabled, will show `{node_name}` by
default otherwise `tooltip-format`.
Format replacements:
`{volume}` - Volume in percentage
`{node_name}` - The node's nickname (`node.nick` property)
Buttons come with an intrinsic min-width but lack a method to alter this
property. Setting the requested size to zero has also no effect on it.
The only way found to work is to hard code the CSS into the button.
gtk requires some chars (<>&"') to be encoded for them to render
properly. `sanitize_str` sanitizes raw strings that have such chars and
returns a properly encoded string
The AButton class is designed as full a substitute to ALabel. The
GtkButton attribute 'button_' is initialized with a label. This
label can the be referenced by the subsequent inheritors of AButton
instead of the GtkLabel attribute 'label_' of ALabel.
For convenience a GtkLabel* 'label_' attribute is added to AButton.
If the button cannot be clicked it is disabled, effectively acting
like its label predecessor.
GtkButton seems to catch one-click mouse events regardless of the
flags set on it. Therefore, 'signal_pressed' is connected to a
function creating a fake GdkEventButton* and calling 'handleToggle'
(for details on this possible bug in GTK see:
https://stackoverflow.com/questions/45334911 )
In accordance with other GtkButtons (i.e. the sway/workspace ones)
set_relief(Gtk::RELIEF_NONE) is called on the 'button_' instance.
This commit adds support to reading the config base path from the
environment variable `WAYBAR_CONFIG_DIR`. If it is set, but no
configuration is found there, it falls back to the previous mechanism
of using the default paths, without erroring.
currently, the orientation of group modules is always the opposite of
the bar. Change it so that:
* the default orientation of the group module is always the opposite of
its parent, even for nested groups
* the orientation can be overridden in the config
* css ID and class are set for the group element
Use inotify listening devices path changes to implement hotplug support.
The new hotplug thread is also an event loop, so the interval value has

Fix libinput_interface object life-time.
Use libinput event for keyboard state updates.
The state will update when CAPS_LOCK, NUM_LOCK or SCROLL_LOCK has been

When adding a custom module with a name, e.g.:
```jsonc
{
...,
"custom/foo#bar": { },
...
}
```
The custom module does not retain the `bar` class as it should, because
all the classes are replaced with the runtime output:
1b4a7b02f4/src/modules/custom.cpp (L141-L147)
Avoid removing the module instance name class so css class behavior is
consistent between all modules.

1. battery.hpp - added local bool variable. Force to print warnings the

does not bring a mess when the battery is turned off (gamepads, etc.)
2. dir_name is an object which takes a part in comparison. So converted to the string.
If the modifier is pressed and release without another event, the
intended behaviour is to clear an urgency hint and hide the bar again.
Note that if multiple workspaces have the urgency hint set, the bar is
hidden again and an urgent workspace is focused, the bar does not stay
hidden anymore.
Add a second reason to show the bar besides visible by modifier.
Update the visibility based on changes in the workspace urgency.
Check all workspaces for urgency and keep the bar visible if at least
one has an urgency hint.
As we always use the enum to compare or initialize uint32_t values, it
would be better to declare it with the right type. This way we could
avoid `-Wnarrowing` warnings or unnecessary type casts.

There is a double delete situation which causes a SIGSEGV to happen
during destruction of bar.
This was introduced by the group feature patch.
The same object pointer is stored in two different vectors of
unique_ptr<AModule> element. Replace with shared_ptr to handle
reference counting correctly and avoid double delete.
Introducing new tooltip placeholder: {timezoned_time_list}. It will be replaced with the list of times in different time zones.
I've found it useful to hover the mouse pointer on time and see time in all my timezones at once.
Current timezone excluding from the list, so if you will scroll over the time module and change the active timezone, this timezone will be excluded from the list and the previous active zone will be added.
After this refactoring:
1. Timezones parses only once on start and the we refer to saved values. All time_zone.isString() checks gone to the constructor.
2. Single timezone case handling as case of multi timezoned logic.
3. Scroll event seems more clear now.
4. Tooltip template parses on start to check if there calendar placeholder or not. To do not calculate calendar_text() if not necessary.
Also fixed timezones behavior: now waybar starting with the first timezone in timezones list and falling back to timezone field only if timezones omit or has no elements.
This fixes issue #610 by reading bandwidth usage per-interface from
/proc/net/dev instead of globally via /proc/net/netstat. It supports the
same matching logic as elsewhere, so setting interface to '*' should
display the same sum-total bandwidth usage as the previous
implementation.
On the `Passive` value of `Status` tray items would be hidden unless
`show-passive-items` is set to true.
On the `NeedsAttention` value of `Status` tray items will have a

In a system with multiple sinks, the default sink may not always be
the once currently being used. It is more useful to control the
currently active sink rather than an unused one.
This patch does not make any difference if the system only uses the
default sink.

The changes in GCC 11.x made `std::condition_variable` implementation
internals `noexcept`. `noexcept` is known to interact particularly bad
with `pthread_cancel`, i.e. `__cxxabiv1::__force_unwind` passing through
the `noexcept` call stack frame causes a `std::terminate` call and
immediate termination of the program
Digging through the GCC ML archives[1] lead me to the idea of patching
this with a few pthread_setcancelstate's. As bad as the solution is, it
seems to be the best we can do within C++17 limits and without major
rework.

IFLA_CARRIER allows to know when a cable is plugged to the Ethernet
card or when the WiFi is connected. If there's no carrier, the
interface will be considered disconnected.
Last part of the rework of handleEvents(), this time we take the
getExternalInterface() function and add it to the handleEvents()
function. That way, waybar can react immediately when a new "external
interface" is available and doesn't need to probe. Also that avoid to
have two different functions consuming from the same socket and we
don't need to recode some of the functions that are already available
via libnl (to send and receive messages).
In order to get the IP address of an interface, we can get the
information out of NEWADDR events without needed to call getifaddrs().
And when now events are expected, we can requests a dump of all
addresses and handle addresses changes the same way via handleEvents()
only.
Instead of using an alternative way to list all links in order to
choose one when an "interface" is in the configuration, we can ask for
a dump of all interface an reuse the handleEvents() function.
This patch also start to rework the handleEvents() function to grab
more information out of each event, like the interface name.
Rewrites window title according to config option "rewrite".
"rewrite" is an object where keys are regular expressions and values are
rewrite rules if the expression matches. Rules may contain references to
captures of the expression. Regex and replacement follow ECMA-script
rules. If no regex matches, the title is left unchanged.
example:
"sway/window": {
"rewrite": {
"(.*) - Mozilla Firefox": " $1",
"(.*) - zsh": " $1",
}
}
(Fixes #358.)
Subprocesses created for custom module scripts were previously left
running when the parent Waybar process exited. This patch sets the
parent-death signal of child processes (PR_SET_PDEATHSIG on Linux,
PROC_PDEATHSIG_CTL on FreeBSD) to SIGTERM.
Caveats:
* This uses Linux-specific or FreeBSD-specific calls. I don’t know if
this project targets other systems?
* There is a possibility that Waybar exits after calling `fork()`, but
before calling `prctl` to set the parent-death signal. In this case,
the child will not receive the SIGTERM signal and will continue to
run. I did not handle this case as I consider it quite unlikely, since
module scripts are usually launched only when Waybar starts. Please
let me know if you think it needs to be handled.
Testing:
* With `htop` open, run Waybar v0.9.5 with a custom module that has an
`exec` script. Terminate the Waybar process and notice that the
script’s subprocess stays alive and is now a child of the init
process.
* Run Waybar with this patch and follow the same steps as above. Notice
that this time the script’s subprocess terminates when the parent
exits.
Open rfkill device only once per module.
Remove rfkill threads and use `Glib::signal_io` as a more efficient way
to poll the rfkill device.
Handle runtime errors from rfkill and stop polling of the device instead
of crashing waybar.
Speedup battery state update by only updating the battery list when we

Initialize the value to prevent the error.
Invisible bar on a `top` layer would still intercept pointer events and
stop them from reaching windows below. Always changing the layer to
to `bottom` along with making bar invisible would prevent that.
Extract two surface implementations from the bar class: GLSSurfaceImpl
and RawSurfaceImpl. This change allowed to remove _all_ surface type
conditionals and significantly simplify the Bar code.
The change also applies PImpl pattern to the Bar, allowing to remove
some headers and fields from `bar.hpp`.
Other units are all uppercased, so using an uppercased "K" makes it look more consistent (especially when {bandwidthUpBits} or something like that is used).
Use `mode` (`waybar::Bar::setMode`) as a shorthand to configure bar
visibility, layer, exclusive zones and input event handling in the same
way as `swaybar` does.
See `sway-bar(5)` for a description of available modes.
Implement a wrapper over Glib::Dispatcher that passes the arguments to
the signal consumer via synchronized `std::queue`.
Arguments are always passed by value and the return type of the signal
