Multi-line Comments not considered as Blocks about emacs-scala-mode

Cool, I didn't spot it, I'll do the PR then.
It seems doable even for a elisp newbie like me :D
(especially because those multiline comments are like the java's one)

Since hs-minor-mode is part of emacs proper, you can add support for it in emacs-scala-mode.

Just do a PR that adds the needed configuration.

As I understand it, the only thing you need to do is to add the required regular expressions for comment start and end to the hs-special-modes-alist list (https://www.emacswiki.org/emacs/HideShow).

I tried with this code

(push (purecopy '(scala-mode "{" "}" "/[*/]" nil nil)) (cdr (last hs-special-modes-alist)))

as for c-mode and java-mode and if you place the cursor on a multi-line comment executing hs-hide-block it works, hiding the comment properly

BUT 😄 if you put the cursor at the beginning of a class and execute the hs-hide-level the comments are not hid as for the content of defs.
Someone has any idea why this is happening?
I attach a gif so you can see by yourself

And you are sure that is not what is supposed to happen?

Personally I expected to see that collapsed as a normal block, but I don't know how HideShow works internally.

[hvesalai]

Can you open some Java code and see what happens.

I checked copying a java file from a random github java repo. Seems It behaves the same way. Then, I suppose it's right.

I'll rise a PR if you can suggest me where to put the extra line. As I said I'm a noob of elisp and modes :D

And maybe I'll just create a custom elisp function for collapsing all comments into the current block into my config ;)
