如何获得当前焦点容器的布局（例如“splith”、“tabbed”）？我想最好的方法是解析swaymsg -t get_treeusing的 JSON 输出（下面的示例） jq，但我不确定如何处理这些“n-debth 树”。
这可能是一个非常基本的问题，但这是我第一次处理 json
“附件”：示例 JSON 输出swaymsg -t get-tree
这是上述命令的输出，其中打开了 3 个终端，其中焦点终端的属性为“focused”:true。

答案1
您可以使用recurse函数jq来递归地遍历nodesof root、output、workspace和containers （以及任何嵌套容器）。使用该select函数，您可以仅过滤出焦点容器并获取键的值layout。
swaymsg -t get_tree | jq 'recurse(.nodes[]) | select(.nodes[].focused == true).layout'
