Log File

No response

This feature is format on type, which is based on what vscode thinks is the indentation of the current file.

yeap, Lua.typeFormat.config.format_line: "false"
disables this, thank

Nevertheless Select indentation has no effect

also, looks like need a Lua.typeFormat.enable option

this is vscode basic config

But what if I don’t want to disable this for another lua formatter?

No other lua plugin supports type format.

emmyluacodestyle is lua's only fully functional formatter with vscode support.

hm, i use stylua
or what you mean by 'fully functional'?

It's good to use stylua, so my explanation doesn't matter.

See this also on emacs using lsp-mode. Looking at the trace from the logs emacs is sending the following options in the textdocument/onTypeFormatting message:

  "options": {
    "tabSize": 2,
    "insertSpaces": false,
    "trimTrailingWhitespace": true,
    "insertFinalNewline": true,
    "trimFinalNewlines": true
  },

These options get ignored and the server always responds by reformatting one or more proceeding lines using an indent level of 4 characters and indenting with spaces despite me having the following settings in my .editorconfig

[*.lua]
indent_size = 2
indent_style = tab
tab_width = 2
insert_final_newline = true
end_of_line = lf
trim_trailing_whitespace = true
max_line_length = 120

Heres an example full message (with the filename elided)

  "textDocument/onTypeFormatting": {
    "uri": "<removed>"
  },
  "options": {
    "tabSize": 2,
    "insertSpaces": false,
    "trimTrailingWhitespace": true,
    "insertFinalNewline": true,
    "trimFinalNewlines": true
  },
  "ch": "\n",
  "position": {
    "line": 1336,
    "character": 0
  }
}

I'm not 100% sure if this is always the case but this problem manifests most noticably when the lines being reformatted are actually already correctly indented. In other cases I think the server returns the correct formatting adjustment.
