Resolves a segfault when waybar is run within a VM on apple silicon.
1. battery.hpp - added local bool variable. Force to print warnings the
only once in order to warn user about wrong battery configuraion. And
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.
Reading brightness value for backlight device can fail intermittently
(particularly when using ddcci-driver-linux). Handle this more
gracefully rather than crashing
Don't set the anchor for certain edges when the width or the height
is not set to a value of 'auto' (1).
When the bar is vertical, the top and bottom edges are not anchored
otherwise the left and right edges are not anchored.
This resolves an issue wherein the width and height set for the
layer-shell were ignored because the layer was set to anchor to all
edges.
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.
According to the [sysfs class power ABI],
/sys/class/power_supply/<supply_name>/status may contain "Not charging".
This is already handled by status_gt() and update() (where ' ' is
converted to '-' for use in config keys) but was not being read due to
skipws. Read with std::getline() to handle this case.

Stop using private implementation details of the `formatter<std::tm>`.
We never needed anything from the class besides the format specifier,
which is easily obtainable with public API.
Ensure that sway workspaces are always displayed in the same order as
used internally by sway. The previous sorting code always sorted
unnumbered workspaces lexicographically. This isn't the order used by
sway internally. Therefore, commands such as "workspace next" might have
jumped arbitrarily in waybar.
This commit reworks the sorting code such that the internal order is
always obeyed. Additionally, numbered persistent workspaces are inserted
at their natural position at the front of the workspace list while
unnumbered ones are appended. This should match the expectations of
workspace ordering known from sway's behavior.
The changes make the configuration property "numeric-first" unnecessary
as this will always be the case now. There's also no reasonable way
around this behavior now. Otherwise, persistent workspaces would jump
around in the visual representation as soon as they become known to
sway.

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.
Allow changing existing modes and adding new ones via `modes`
configuration key.
`modes` accepts a JSON object roughly described by the following type
```typescript
type BarMode = {
layer: 'bottom' | 'top' | 'overlay';
exclusive: bool;
passthrough: bool;
visible: bool;
};
type BarModeList = {
[name: string]: BarMode;
};
```
and will be merged with the default modes defined in `bar.cpp`.
Note that with absence of other ways to set mode, only those defined in
the `sway-bar(5)`[1] documentation could be used right now.

I was seeing "[warning] Requested height: 20 exceeds the minimum height: 30 required..."
Lines 114-134 are relevant; 133 overrides the requested height with the minimum height when GTK wants more pixels to work with. So, the code is behaving as expected, and "less than" matches the code's logic.
When natural scrolling is enabled, the behaviour of scrolling on pulseaudio
module is reversed, this commit reverses the direction of scroll variable
if "reverse-scrolling" is set to 1 in config file.
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.
`show_all` call from `Tray::update` attempts to walk the widget tree and
make every widget visible. Since we control individual tray item
visibility based on `Status` SNI property, we don't want that to happen.
Modify `Tray::update` to control the visibility of a whole tray module
only and ensure that the children of `Item` are still visible when
necessary.
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.
- Delete previous Layout before creating next one, and in destructor
- Use stack XKBContext instead of local new+delete
- Lock mutex in update() as it is called from a different thread than onEvent(res)
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
`.needs-attention` CSS class.
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.

Whenever the network module is configured with both "format" and
"format-$state" and when the module use "format-$state" once, it
override the value that was saved from "format".
For example, if both "format" and "format-disconnect" are configured,
and only those, as soon as the module show information about a
disconnected interface, it will keep showing the format for
disconnected, even if the interface is connected again later.
Fix that by always setting a value to default_format_ in update() and
thus use the intended default format when needed.
Fixes#1129
When an interface's state is change to "down", all the route
associated with it are deleted without an RTM_DELROUTE event.
So when this happen, reset the module to start looking for a new
external interface / default route.
Fixes#1117
The check to figure out if we have the default route should be after
the for loop that parses the route attributes, to avoid acting on
incomplete information. We are going to use more fields from the
message.
The module doesn't update the `essid_` as soon as a WiFi interface is
connected, but that happens at some point later, depending on
"interval" configuration.
Fix that by rerunning the get WiFi information thread when the
`carrier` state changes. Also, we will clear the state related to WiFi
when the connection is drop to avoid stale information.
Some RTM_NEWLINK messages may not have the IFLA_CARRIER information.
This is the case when a WiFi interface report scan result are
available. `carrier` is used regardless of if it is present in the
message or not. This would result in the interface appearing
"disconnected" in waybar when it isn't.
This patch now check that `carrier` is available before using it.
The same thing could potentially happen to `ifname` so check if it's
set before recording it.
Fixes: c1427ff (network: Handle carrier information)
Fixes#388
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.
When more than one message is available to read on the ev_sock_
socket, only the first one is read.
Make some changes to be able to read all the messages available by
setting the socket to non-blocking. This way we can detect when
there's nothing left to read and loop back to wait with epoll.
Fix modules starting with no text, but not hidding.
Start with some "text" in the module's label_, update() will then
update it. Since the text should be different, update() will be able
to show or hide the event_box_. This is to work around the case where
the module start with no text, but the the event_box_ is shown.
`format-discharging-full` has been impossible since #923 made it
impossible to be full and discharging at the same time. This should
fix that by only making `format-charging-full` impossible. Whether
or not that should be allowed is a good question, but beyond the
scope of this change.

std::regex and std::regex_replace may throw an std::regex_error if the
expression or replacement contain errors.
Log this error and carry on with the next rule, so that the title is
shown even if the config contains errors.
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",
}
}
Allow the user to show the current volume from MPD status via the
`format` and/or `tooltip-format` configuration options.

output plugins like `pulse` support volumes above 100%.

On some systems (eg: ARM) the supported frequencies of the CPU are not
properly reported by /proc/cpuinfo so if that fails try to retrieve them
from /sys/devices/system/cpu/cpufreq/policy[0-9]/cpuinfo_[max|min]_freq.
Moving rfkill to the main event loop had unexpected side-effects.
Notably, the network module mutex can block all the main thread events
for several seconds while the network worker thread is sleeping.
Instead of waiting for the mutex let's hope that the worker thread
succeeds and schedule timer thread wakeup just in case.
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.
Kernel 5.11 added one more field to the `struct rfkill_event` and broke
unnecessarily strict check in `rfkill.cpp`. According to `linux/rfkill.h`,
we must accept events at least as large as v1 event size and should be
prepared to get additional fields at the end of a v1 event structure.
Multiple .done events may arrive in batch. In this case libwayland would
queue xdg_output.destroy and dispatch all pending events, triggering
this callback several times for the same output.
Delete xdg_output pointer immediately on the first event and use the
value as a guard for reentering.
At this point we're not awaiting any protocol events and flushing
wayland queue makes little sense. As #1019 shows, it may be even harmful
as an extra roundtrip could process wl_output disappearance and delete
output object right from under our code.
Ignore any further xdg_output events. Name and description are constant
for the lifetime of wl_output in xdg-output-unstable-v1 version 2 and we
don't need other properties.
Fixes#990.
Add additional fields, namely `source_volume` and `source_desc`
Add `tooltip-format`, reverting to default behavior if not specified
Add additional CSS classes, namely `sink-muted` and `source-muted`
Destroy request is not specified for foreign toplevel manager and it
does not prevent the compositor from sending more events.
Libwayland would ignore events to a destroyed objects, but that could
indirectly cause a gap in the sequence of new object ids and trigger
error condition in the library.
With this commit waybar sends a `stop` request to notify the compositor
about the destruction of a toplevel manager. That fixes abnormal
termination of the bar with following errors:
```
(waybar:11791): Gdk-DEBUG: 20:04:19.778: not a valid new object id (4278190088), message toplevel(n)
Gdk-Message: 20:04:19.778: Error reading events from display: Invalid argument
```
This error occurs because of an incorrect assumption that the size of
the list of nodes that contains the focused window is the number of
windows in a workspace.
The windows in a workspace are stored as a tree by Sway, rather than a
list, so the number of windows has to be found by counting the leaves of
a workspace tree.
GDK Wayland backend can emit two events for mouse scroll: one is a
GDK_SCROLL_SMOOTH and the other one is an emulated scroll event with
direction. We only receive emulated events on a window, thus it is not
possible to handle these in a module and stop propagation.
Ignoring emulated events should be safe since those are duplicates of
smooth scroll events anyways.
Fixes#386
Previously we only checked when connecting to the server whether it had
the minimum required version but didn't act accordingly in the various
functions that use the functionality of later versions. If there were a
server in the wild, that actually would not have this functionality,
there would have been a crash. Fix this by checking the version before
using the functionality and gracefully abort it.
There was an update the of the toplevel manager protocol. Unfortunately,
there are no new interesting updates with regard to the taskbar
implementation. Nonetheless, update the protocol xml files to the latest
version so that the implementation is up-to-date.
While being there, also change the debug warning that is shown when
there is a version mismatch between the server and client version of the
protocol.
Speedup battery state update by only updating the battery list when we
get a CREATE/DELETE event in the directory or whenever we do a full
refresh on the interval.
There was one uninitialized value warning and two mismatched-sign
compare warnings. They both appear valid, the first occurring when MPD's
"format-stopped" contains {songPosition} or {queueLength} and the second
occurring when the clock's "timezones" array is more than 2 billion
items long (not likely, I admit). Fix both issues.
This is very useful when writing CSS that affects more than just a
single widget. Pass `-l debug` to enable debug logging and show this
information.

full-at was capped at the value instead of allowing the battery to show
100% when you were at the full-at value. Uncapping makes more sense as
it makes the full-at value the new 100% and the scale goes down from
there. Whereas before the battery would stay at the full-at value until
it went down enough which is unrealistic.
Since we're now clamping at 100% and rounding, mark as full at that
point. Some batteries will stay in charging state for a long time while
stuck at the same charge level. Just mark them as full to not be
confusing.
