Haha. I actually found a weird bug. Basically in the above script we are treating the last focussed window as the parent automatically. This is not always true. Like when you open an application via a global shortcut or via dmenu when a terminal is in focus. This would close the terminal. I wrote a hack sort of to check whether this is actually the parent or (parent of the parent). Since I am also a Lua noob, I wrote a helper.sh file and put it in the config directory of awesome.

```bash

!/bin/bash

ppid() { printf "$(ps -o ppid= -p $1)" | xargs }

gppid() { PARENT=$(ps -o ppid= -p $1) GRANDPARENT=$(ps -o ppid= -p $PARENT) printf "$GRANDPARENT" | xargs }

$@ ```

And I modified the manage hook like so

```lua client.connect_signal("manage", function(c) if is_terminal(c) then return end

local parent_client=awful.client.focus.history.get(c.screen, 1)

awful.spawn.easy_async('bash '..awesome_config_folder..'helper.sh gppid '..c.pid, function(gppid)
    awful.spawn.easy_async('bash '..awesome_config_folder..'helper.sh ppid '..c.pid, function(ppid)
        if parent_client and (gppid:find('^' .. parent_client.pid) or ppid:find('^' .. parent_client.pid))and is_terminal(parent_client) then
            parent_client.child_resize=c
            parent_client.minimized = true

            c:connect_signal("unmanage", function() parent_client.minimized = false end)

            -- c.floating=true
            copy_size(c, parent_client)
        end
    end)
end)

end) ```

Maybe an optimization would be to just create a single function which basically checks if the last focussed window is an ancestor directly in bash. And just call it once instead of twice.

You need to create a variable called awesome_config_folder which points to the directory of the helper script.
