Cannot for the life of me configure formatting

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

MacOS

What is the issue affecting?

Formatting

Expected Behaviour

Formatting adds 6 spaces for indentation.

Actual Behaviour

Formatting adds the default 2.

Reproduction steps

I have it set as the default formatter in my settings.json:

  "[lua]": {
    "editor.quickSuggestions": {
      "other": true,
      "comments": true,
      "strings": true
    },
    "editor.tabCompletion": "on",
    "editor.quickSuggestionsDelay": 1,
    "editor.suggest.snippetsPreventQuickSuggestions": false,
    "editor.defaultFormatter": "sumneko.lua",
  },

I put in .luarc.json in my workspace:

{
  "Lua.format.defaultConfig": {
    "indent_style": "space",
    "indent_size": "6"
  }
}

But no luck,

I put in .vscode/settings.json in my workspace:

{
  "Lua.format.defaultConfig": {
    "indent_style": "space",
    "indent_size": "6"
  }
}

I try various ways of adding this to the core settings.json used by VSCode, either adding it under the [lua] entry, or as a top level entry, but no luck.

What am I missing?!

thanks!

示されている settings.json、.luarc.json、.vscode/settings.json の設定を使用して、Visual Studio Code のフォーマット動作を再現する。language server がフォーマット設定をどのように読み取るかを追跡し、indent_size 6 が無視される理由を特定する。完了の条件は、文書化された workspace 設定によって 6 個のスペースでインデントされることとする。
