Such a property (almost) already exists and is called _NET_WM_DESKTOP. It is
used for saving the first (and only the first, this is the "almost" part) tag
that a client is attached to (mostly because EWMH demands this).
After parsing the config, the C code goes through all already-existing clients
and manages them (thus creates client objects for them and call the manage
signal). Before emiting the manage hook, the C code checks if the client has the
_NET_WM_DESKTOP property set and tags it with the appropriate tag. This is done
in the following C code:
reply = xcb_get_property_reply(globalconf.connection, c0, NULL);
if(reply && reply->value_len && (data = xcb_get_property_value(reply)))
{
desktop = *(uint32_t *) data;
if(desktop == -1)
c->sticky = true;
else if (desktop >= 0 && desktop < globalconf.tags.len)
for(int i = 0; i < globalconf.tags.len; i++)
if(desktop == i)
{
luaA_object_push(globalconf.L, globalconf.tags.tab[i]);
tag_client(c);
}
else
untag_client(c, globalconf.tags.tab[i]);
else
/* Value out of bounds, just give it the first tag */
if (globalconf.tags.len > 0)
{
luaA_object_push(globalconf.L, globalconf.tags.tab[0]);
tag_client(c);
}
}
This does work with the default config. Now why doesn't it work with your
config?

After your config was parsed, there is only a single tag (at least I guess so).
Thus, the above code cannot tag the client appropriately.
I hope this clears up the current state. Feel free to come up with suggestions
on how to improve this.
Cheers,
Uli
