This adds a new ‘poll-interval’ option to the network module. When set
to a non-zero value, the following Wi-Fi stats will be updated:
* Signal strength
* RX+TX bitrate
This cleans up the nl80211 handling quite a bit, and adds initial
support for nl80211 notifications.
* We now join the nl80211 MLME multicast group (done by parsing the
CTRL_ATTR_MCAST_GROUPS attribute in the reply to our
CTRL_CMD_GETFAMILY request). This gives us CONNECT and DISCONNECT
notifications, allowing us to request and reset SSID that way, instead
of detecting the link’s OPER state.
* Before parsing an nl80211 message, verify it’s for us, by looking
for a NL80211_ATTR_IFINDEX attribute in the message (and comparing the
contents with our previously detected ifindex).
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.
Previously, only the date command inside the script was run with
LC_TIME=C.
But there’s no reason to be that conservative; we absolutely do not
want _anything_ in that script to generate locale dependent output.
* Bind the foreign-toplevel-manager object *after* the first round of
global objects. This ensures we bind all pre-existing wl-output
objects before binding the toplevel manager. This is important, since
otherwise we wont get any output_enter() events for the initial set of
toplevels.
* Bind xdg-output-manager, to be able to bind xdg-output objects for
each wl-output.
* Add xdg-output-listener to each wl/xdg-output, to be able to get the
outputs’ names.
* Add a list of outputs to each toplevel. The output_enter() event
adds to this list, and output_leave() removes from it.
* Add option ‘all-monitors’. When not set (the default), toplevels are
only included in the generated content if they are mapped on the same
output as the bar itself. When *not* set, all toplevels are always
included in the generated content.
* ‘content’ is a template; the module returns a list of toplevels,
each one instantiated using the content template.
* Each toplevel has 6 tags:
- app-id (string)
- title (string)
- maximized (bool)
- minimized (bool)
- activated (bool)
- fullscreen (bool)
To show the application name and title of the currently active window,
one can do:
- foreign-toplevel:
content:
map:
tag: activated
values:
false: {empty: {}}
true: {string: {text: "{app-id}: {title}"}}
