Cycle through clients on both screens in awesomewm

Question

I am using awesomewm and have two monitors, so Mod4+j and Mod4+k cycle through windows on current screen only. Is there a way to cycle through all windows/clients on all screens to make it work like ordinary Alt+Tab?

Answer 1

I'm not sure when this capability was added, but I believe you're looking for

client.focus.global_bydirection (dir, c)

Focus a client by the given direction. Moves across screens. Parameters:

• dir: The direction, can be either "up", "down", "left" or "right".
• c: Optional client.

Answer 2

After poking around awful module docs i found a solution. It is hacky, but it works as I wanted it to work.

awful.key({ modkey,           }, "Tab",
    function ()
        awful.client.focus.byidx(1)
        if awful.client.ismarked() then
            awful.screen.focus_relative(-1)
            awful.client.getmarked()
        end
        if client.focus then
            client.focus:raise()
        end
        awful.client.togglemarked()
    end),

This function cycles through clients on current screen, marking them and when they all are marked, jumps to the next screen. Here is what happens step by step:

• we focus the next client
• we check if it is marked and if it is, we move to the next screen and clear marked status from all clients on it
• we raise current client
• and mark it

It is funny because i do not know what "marked" means. Marked clients do not seem to differ from not marked clients visually or by behaviour.

It is strange that i had to write a 10 line function to get something as trivial as multiscreen alt-tab. I might have done something excessive)
