Add Super + Shift + J to toggle a wide 2/3 - 1/3 window split

[felipecpaiva]

Dwindle splits two windows 50/50. That is the wrong ratio for the most common two-window setup: one window you are working in, one you are only glancing at (docs, a terminal tailing logs, a chat window). The reading window wants two thirds.

Super + Shift + J toggles the active split between an even 50/50 and 2/3 - 1/3, so it pairs naturally with Super + J ("Toggle window split") on the same key.

local split_wide = false
o.bind("SUPER + SHIFT + J", "Toggle wide window split", function()
  local ratio = split_wide and 1.3333 or 1.0
  local aw = hl.get_active_window()
  if aw then
    for _, w in ipairs(hl.get_windows()) do
      if w.workspace and w.workspace.id == aw.workspace.id and w.address ~= aw.address and w.at.x < aw.at.x then
        ratio = 2 - ratio -- focused window is on the right; grow it instead of the left one
        break
      end
    end
  end
  local ok = pcall(hl.dispatch, hl.dsp.layout("splitratio " .. tostring(ratio) .. " exact"))
  if ok then
    split_wide = not split_wide
  end
end)

splitratio 1.0 is an even split. splitratio always grows the split's first (left/top) child — not whichever window is focused — so the binding now checks the focused window's position and flips the ratio when it is the second (right/bottom) one, before dispatching. Using exact rather than a relative step means the two states are stable no matter how the split was dragged beforehand.

Notes:

• Super + Shift + J was unbound in default/, so nothing is displaced.
• Same scope as the existing Super + J: it acts on the active dwindle node. Under any other layout (e.g. scrolling), splitratio has no handler and Hyprland raises a Lua runtime error — the pcall above catches that so the binding is a true no-op there instead of showing an error notification.
• Hyprland has no getter for a node splitratio, so the toggle state is a module local. After hyprctl reload the first press may need a second press to resync. That is the same trade-off already accepted elsewhere, and it seemed better than adding a state file for a transient visual toggle. Happy to switch it to a bin/omarchy-hyprland-window-split-toggle script with state under ~/.local/state/omarchy/ if you prefer the script convention.

Verified on Omarchy with two tiled windows on a 1920x1200 display at 1.25 scale: the active window moves between 764px and 1020px of the 1536px logical width and back, repeatably, regardless of which of the two windows is focused.

Update: the original version always grew the left/top window and threw a runtime error under non-dwindle layouts. Fixed both above.
