Enable Follow mode for helm-org-in-buffer-headings

Question

I want to enable helm-follow-mode for helm-org-in-buffer-headings. This is what I have so far:

(add-hook 'helm-after-initialize-hook 
            ((lambda () (helm-attrset 
                         'follow 1 helm-org-in-buffer-headings))))

But not working yet. Any ideas?

Answer 1

I found a few clues here and this is what worked for me:

(with-eval-after-load "helm-org"
  (cl-defmethod helm-setup-user-source ((source helm-org-headings-class))
    (set-slot-value source 'follow 1)))
