change root dir or enter file [Question]

[ghost]

Hi
I am trying to achieve the following behaviour:
TAB = (1) expand node
RET =
(2) if node is directory, change root to it
(3) if node is a file, open it

Not sure how to achieve this, I've tried with

(define-key neotree-mode-map (kbd "RET") 'neotree-change-root)

that accomplishes (1) and (2) but ruins (3)

How could I do it?

Thanks

A bit of why would anyone (or at least me) this behaviour.. becouse sometimes I want to explore the tree and then decide a directory to work on

(define-key map (kbd "RET")     (neotree-make-executor
                                     :file-fn 'neo-open-file
                                     :dir-fn  'neo-open-dir))

The default behaviour RET have accomplished the (2) and (3)

The above isn't working for me.

I've tried neotree-change-root and neo-buffer--change-root in the above.

I'm looking to have RET always change root dir..

Any help would be appreciated!

Late reply.

Try with a lambda function:

(define-key neotree-mode-map (kbd "RET")  
        (neotree-make-executor :dir-fn  '(lambda (full-path arg) (neotree-change-root))))

I'm not sure this will work.
