This mostly comes down to tracking whether each channel is a playback,
or capture channel, and using the appropriate APIs when dealing with
it.
Some cleanup related to this:
* Add a channel struct, for per-channel data. Previously, our channel
list was just a list of ALSA channel IDs.
* We now store current volume per-channel (but volume min/max is
per-device)
* Muted state is stored per-channel
* Track both the device’s playback and capture volume ranges, as well
as whether the device *has* playback or capture volume.
* Get the playback/capture volume ranges once, during init, instead of
at each update.
* Use struct pointers for the volume/muted channels. This way we don’t
have to iterate all channels and to string comparisons on the name
each time we update our state.
These options allows you to select which channel to use as volume
source, and which channel to use as the source for the muted state.
With this, we can also remove the check for *all* (playback) channels
having the same volume/muted state. And with that, we no longer need
to warn when not all channels have the same volume/muted state.
With this patch, a non-existing ALSA device is no longer considered a
fatal error. Instead, we keep retrying until we succeed.
Furthermore, if we have successfully opened the ALSA device, and it
then disappears, we a) no longer crash, or cause 100% CPU usage, and
b) try to re-connect to the device.
With this, we now handle e.g. USB soundcards being disconnected and
then re-connected. We should also handle pseudo devices, like pipewire
provides ones, when yambar is started before pipewire.

If the module is empty (width is 0) no spacing will be rendered for it.
This makes modules that auto-hide (for example, network modules for interfaces not used all of the time) occupy no space in the bar.
When set, river tags and seats’ view titles apply to the output yambar
is on, only.
The default is disabled, which implements the old behavior, where
river tags and seats’ view titles represent the union of all
outputs.
This allows you to configure the width of each side of the border
individually. border.width can still be used, and will set all four
borders to the same width.
Closes#77
Add ‘persistent’, a list-of-strings specifying workspace names that
should be persistent. That is, workspaces that should never be
removed, even if empty.
Note that the workspaces _are_ still destroyed (in i3/Sway), but
yambar keeps abstractions for them around. This is useful to e.g. keep
a strict order between your “core” workspaces.
Closes#72
First, apply max-len to the converted wide character string, instead
of the UTF-8 string. This is better, and more correct, since UTF-8 is
multibyte, and applying max-len to that results in strings _shorter_
than max-len.
Second, use HORIZONTAL ELLIPSIS (…) instead of three regular
periods (...) as truncation character. This “saves” 2 characters.
To be able to do this, the conversion to a wide character, and glyph
rasterization is now done when the exposable is instantiated, instead
of in begin_expose().
Closes#73
When set to a non-negative value, the script module will call the
configured script every <poll-interval> second.
In this mode, the script is expected to write one tag set and then
exit.
This is intended to simplify the implementation of scripts that would
otherwise just do a loop + sleep.
Closes#67
Some battery drivers will remove their sysfs directory when the
battery goes from charging to discharging, or vice verse.
This caused yambar’s battery module to terminate, resulting in the
last known battery state to “freeze”.
With this patch, failure to read the battery directory the *first*
time is still considered a hard failure, resulting in an error message
and then termination.
However, subsequent failures, i.e. while polling the battery state,
is *not* considered fatal; we simply don’t update the bar, and retry
again the next poll interval. Error messages are still logged however.
Closes#44
