Ruby syntax highlight, code folding with emacs

ruby-talk
1

I am trying to get Ruby syntax highlighting and code folding to work with
gnu emacs. I’ve loaded the necessary .el files (ruby-mode, inf-ruby,
rubydb3x). Turned on syntax highlighting (Global font lock mode).

But I cannot get

  • *.rb files to automatically enter Ruby mode
  • syntax highlights (after I manually set ruby mode)

Separately, is there any code-folding (major or minor) mode available?

Any pointers appreciated.

Thanks

(“\.gem$” . ruby-mode)
(“\.gemspec$” . ruby-mode)

(setq ruby-mode-hook '(lambda () (font-lock-mode 1)))

I’m not sure. However, from the docs for set-selective-display

C-x $ runs the command set-selective-display
which is an interactive compiled Lisp function in `simple’.
(set-selective-display ARG)

Set selective-display' to ARG; clear it if no arg. When the value of selective-display’ is a number > 0,
lines whose indentation is >= that value are not displayed.
The variable `selective-display’ has a separate value for each buffer.
