I would like to use a style like this: > structure Foo = > struct > fun foo x = x > end > but by default sml-mode indents it like this: > structure Foo = > struct > fun foo x = x > end > Can somebody tell me how sml-mode indentation rules can be configured? I guess the "right" way to do that, would be: (defun my-sml-rules (orig kind token) (pcase (cons kind token) (`(:before . "d=") (if (smie-rule-parent-p "structure" "signature" "functor") 2 (funcall orig kind token))) (`(:after . "struct") 2) (_ (funcall orig kind token)))) (add-hook 'sml-mode-hook (lambda () (add-function :around smie-indent-rules #'my-sml-rules))) But since `add-function' is new in 24.4, you'll probably want something more like: (defadvice sml-smie-rules (around my-sml-rules activate) (let ((i (pcase (cons (ad-get-arg 0) (ad-get-arg 1)) (`(:before . "d=") (if (smie-rule-parent-p "structure" "signature" "functor") 2)) (`(:after . "struct") 2)))) (if i (setq ad-return i) ad-do-it))) -- Stefan "guaranteed 100% untested"
