This patch enables support for nl80211. In case the libnl-genl-3.0
library isn't found, it will fall back to Wext instead.
The library to use can also be manually set with the CMake option
WITH_LIBNL.
The Wireless-Extensions (WE or Wext) are deprecated and long replaced
by cfg80211.
Although Wext isn't used by WiFi drivers anymore, CFG80211_WEXT allows
old tools to communicate with modern drivers by providing a wrapper
API.
The only reason polybar couldn't build without xkb is because the
xkeyboard module's source file was not removed during compilation.
xkeyboard already has an entry in unsupported.hpp
This effectively makes xcb-util-xkb optional
When xrm was disabled, main.cpp was missing the complete defintion of
connection from connection.hpp, which was included xresources.hpp when
xrm was enabled.
It's queried the same way ipv4 addresses are queried, but here it displays globally routable addresses. If there are multiple such addresses, it picks one (same as with ipv4). It's possible that an address discovered this way is not in fact globally reachable but still marked as global.
Using brace initialization here causes bar.hpp to not compile when
included on its own, forcing all clients to also include
tray_manager.hpp and so on, which defeats the purpose of forward
declaring those classes.
This also allows us to remove the tray_manager.hpp, renderer.hpp and
parser.hpp includes from the clients of bar.hpp
As mentioned in #1215, gcc >=8 will complain, if strncpy truncates the
source string or gcc can prove there is no NUL terminating byte.
This also updates the i3ipcpp submodule where there was a similar error
Fixes#1215
atoi, atof and so on have undefined behavior if anything goes wrong. We
now use strto*, but without error checking. In most places overflows and
the like *should* not happen. String to number conversions are only used
when reading data from other applications or from the config, if another
application gives unparsable strings or too large numbers, then most
likely there is something wrong with that application. If the error
comes from the user config, then the user has to live with values
provided by strto* on error (which are very reasonable)
Fixes#1201
There have now been several instances of people reporting that their
bars are not found and polybar not printing the config file name because
the error is thrown first, making it very difficult to debug
Before, polybar would crash, trying to throw a server error because
mpd_connection_get_server_error asserts that the error is of type server
error, but it isn't because it was cleared
