I want to strictly sort my imports by type and defining where to put a newline between.

My json .oxfmtrc.json looks like this:

{
  "experimentalSortImports": {
    "newlinesBetween": false,
    "groups": [
      "value-builtin",
      "value-internal",
      "value-external",
      "value-parent",
      "value-sibling",
      "value-index",
      // { "newlinesBetween": 1 },
      "type-internal",
      "type-import",
      "type-parent",
      "type-sibling",
      "type-index",
      "ts-equals-import",
      // { "newlinesBetween": 1 },
      "unknown",
    ],
  },
}

When I use newslinesBetweeen: true and create subgroups like groups: [[/* all values */], [/* all types*/]], the subgroups order is no longer respected, and all value imports are getting sort alphabetical

possible solution

perfectionist ESLint plugin has a newlinesBetween object which can be passed into groups.
oxfmt does not parse it:

Failed to parse configuration.
Failed to deserialize Oxfmtrc: groups must be an array of strings or arrays of strings
