WM_CLASS not set

[skjnldsv]

Hello! Thanks you very much for taking this project! You're doing an amazing job updating this app.

This issue is more a mix between a problem and an enhancement. If you're using tiling manager like i3 and/or bspwm (on linux), you can set rules to automatically assign application on specific desktops. This require the wm_class info to be defined inside the app. This is a common requirement, most of the app (all of them?) have this data set on linux.

The rules to assign desktops are:

bspc rule -a Vlc desktop=^2
bspc rule -a messengerfordesktop desktop=^6

The problem is that the Messenger app doesn't have the requirements, so the rule can't work.

When using the xprop command, i get the following infos

_NET_WM_USER_TIME(CARDINAL) = 74813799
_NET_WM_DESKTOP(CARDINAL) = 5
WM_NORMAL_HINTS(WM_SIZE_HINTS):
        program specified location: 20, 62
WM_NAME(UTF8_STRING) = "Messenger"
_NET_WM_NAME(UTF8_STRING) = "Messenger"
_NET_WM_ICON(CARDINAL) = 
XdndAware(ATOM) = BITMAP
_MOTIF_WM_HINTS(_MOTIF_WM_HINTS) = 0x2, 0x0, 0x1, 0x0, 0x0
_NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_NORMAL
_NET_WM_PID(CARDINAL) = 2539
WM_LOCALE_NAME(STRING) = "en_US.UTF-8"
WM_CLIENT_MACHINE(STRING) = "hostname"
WM_PROTOCOLS(ATOM): protocols  WM_DELETE_WINDOW, _NET_WM_PING

And for Vlc I get the following data:
