{
    "layout": {
        "menu-layout": {
            "type": "section",
            "title": "Layout and content",
        "keys": [
            "show-category-icons",
            "favbox-show",
            "favbox-min-height",
            "show-places",
        ]
        },
        "menu-behave": {
            "type": "section",
            "keys": [
                "enable-autoscroll",
                "search-filesystem"
            ]
        }
    },
    "favbox-min-height": {
        "type": "spinbutton",
        "default": 300,
    }
}

For example, in this file above teste.json: I want to replace in the item "favbox-min-height", in the key: value "default": 300 for "default": 400

I'm not able to do this, could someone help me do this?

A:

the input invariant solution using jtc is easy:

bash $ <teste.json jtc -w'<favbox-min-height>l[default]' -u400
{
   "favbox-min-height": {
      "default": 400,
      "type": "spinbutton"
   },
   "layout": {
      "menu-behave": {
         "keys": [
            "enable-autoscroll",
            "search-filesystem"
         ],
         "type": "section"
      },
      "menu-layout": {
         "keys": [
            "show-category-icons",
            "favbox-show",
            "favbox-min-height",
            "show-places"
         ],
         "title": "Layout and content",
         "type": "section"
      }
   }
}
bash $
