[Discussion] Why do you need to set configuration information for each language?

foldStart & foldEnd can depend on editor.action.commentLine to some extent. Since you will most likely install plugins when using the target language, you don't need to worry about the comment format. Taking a step back is still possible to customize using the config file

Is there anything special about foldStartRegex & foldEndRegex? Just match if #region or #endregion exists in a single line, so all languages are common.

i tried

async edit => {
                if (!currentLanguageConfig) { return; }
                if (!ate) { return; }

                //Now, move the selection point to the [NAME] position.
                var sel = ate.selection;

                var region_cur_Line = sel.start.line - 1;
                var region_newStartPosition = sel.start.translate(region_cur_Line - sel.start.line, 0);
                var selection_region    = new vscode.Selection(region_newStartPosition, region_newStartPosition);
                var selection_endregion = new vscode.Selection(sel.end, sel.end);

                ate.selections = [selection_region, selection_endregion];

                // 利用 vscode 添加注释
                // await 是为了确保应用了注释
                await vscode.commands.executeCommand(
                    "editor.action.commentLine",
                    "editorHasDocumentFormattingProvider && editorTextFocus",
                    true
                );

                // 格式化后才可以获得准确的位置
                // 也不知道格式化会不会修正选中的位置
                //Format the document
                await vscode.commands.executeCommand(
                    "editor.action.formatDocument",
                    "editorHasDocumentFormattingProvider && editorTextFocus",
                    true
                );

                // Now, move the selection point to the [NAME] position.
                region_newStartPosition = region_newStartPosition.with(region_cur_Line, ate.document.lineAt(region_cur_Line).text.indexOf("#region") + 8);
                var newSelection = new vscode.Selection(region_newStartPosition, region_newStartPosition);
                ate.selections = [newSelection];
            }

    "[xmake]": {
      "foldStart": "#region [NAME]",
      "foldEnd": "#endregion",
      "foldStartRegex": "\\s*#region\\s*.*",
      "foldEndRegex": "\\s*#endregion\\s*.*", 
      "disableFolding": false
    }

xmake uses lua syntax, but my regex doesn't need to match '--' at all
