Hi,


I managed to create an simple function to archive the same goal

  (defun my/indent-rules ()
    `(;;here is my custom rules
      ((parent-is "namespace_definition") parent-bol 0)
      ,@(alist-get 'bsd (c-ts-mode--indent-styles 'cpp)))
    )


Then you would simply (setq c-ts-mode-indent-style #'my-indent-style). I 
followed some guides here: https://casouri.github.io/note/2023/tree-sitter-starter-guide/html-manual/Parser_002dbased-Indentation.html.
