sway 獲取目前焦點容器的佈局
我如何獲得目前焦點容器的佈局（例如’splith’，’tabbed’）？我想最好的方法是解析
swaymsg -t get_treeusing的 JSON 輸出（下面的範例）jq，但我不確定如何處理這些“n-debth 樹”。這可能是一個非常基本的問題，但這是我第一次處理 json
“附件”：範例 JSON 輸出
swaymsg -t get-tree這是上述命令的輸出，其中打開了 3 個終端，焦點所在的終端具有屬性“focused”：true。

您可以使用
recurseof 函式jq遞歸地遍歷nodesofroot、output、workspace和containers（以及任何嵌套容器）。使用該select功能，您可以僅過濾掉焦點容器並獲取layout鍵的值。swaymsg -t get_tree | jq 'recurse(.nodes[]) | select(.nodes[].focused == true).layout'
