Register a layout for long/vertical/portrait monitors

[yamsu]

Hi, this is a terrific addon to i3wm. The following might be useful for folks who have rotated their monitors.

@register_layout
class Layout_MainTop:

    name = "mainTop"
    aliases = ["mt"]
    description = """\
            One large window to the top at 50%,
            all others stacked to the right horizontally.

            -------------
            |           |
            |     1     |
            |           |
            |-----|-----|
            |  2  |  3  |
            -------------
            """

    def get_json(self, window_count):
        return node(
            1,
            "splitv",
            False,
            [node(0.5, "splith", True, []), get_stack(window_count - 1, "splith")],
        )
