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.
The logind feature adds a new inhibitor module which allows to acquire
the inhibitor locks that logind presents.

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
`.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.

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.
