Client disappears when sending to screen

[sandermarechal]

When I use Modkey+o to send a client to another screen (c:move_to_screen()) then the client window simply disappears. I have tried with every combination of:

• Awesome 4.0 (Debian stable)
• Awesome 4.2 (Debian testing)
• Tyrannical 1.0.0
• Tyrannical master

All using Tyrannical's example.rc.lua.

I am pretty sure the bug is with Tyrannical somewhere. If I use Awesome's own default rc.lua (with the 9 tags) then moving clients between screens works fine.

Do you have a selected tag on the second screen? If not, create one, select it and try again.

No I don't. I use a combination of volatile and exclusive tags. I.e. I have a "www" tag on screen 2 for my browsers. When I move one of my browser clients to screen 1 then I expect a "www" tag there to be created. Any idea how I can accomplish that?

Also, I think clients should never just disappear. They should always be added somewhere, or the client is effectively "lost".

Clients disappear when they are not on the current desktop just like in every other WM. The problem is that you have no desktop/tag at all. We have a request::tag signal to all you need to listen to if you want to create a fallback tag.

Untested:

client.connect_signal("request::tag", function(c)
    if #c.screen.tags == 0 then
        awful.tag.add("New tag", {layout = awful.layouts.layouts[1]})
    end
end)

Thanks, I will try that.
Is there any way to have Tyrannical create the correct tag for the client using it's matching strategy, similar to the requests in #80 and #56?
