Long time no see, oh Ruby Talk list. I have a question to any of you out
there who are emacs users. (And yes, this is after searching the web for 2+
days AND archives of mailing lists/newsgroups)
Does anyone out there who uses emacs have a good solution to code folding?
vim kicks the proverbial bum when it comes to code folding. I'd really like
that functionality in Ruby.
I've tried vim and emacs, and emacs is coming to me with more ease. I'm
using ruby-mode. I figured this was probably the best place to ask the
question since if you're here, you're probably using Ruby

Not sure if you were asking how Samantha uses it or how to use it in
general.
:help folding in vim
should give you something to chew on for a while.

While we're on the subject, how *DO* you use code folding in vim?
Excellent folding with easy setup (= do not need to understand almost at all to ':h folding')
In combination with http://vim-taglist.sourceforge.net/ which is somehow related.
The main text deals w/ a quick and dirty way that uses a couple of
commands to hide all the function bodies (class ones too i would
assume), leaving you w/ just the signature line and the end line. Also,
there are some links in the first paragraph to some emacswiki pages.
I'm not sure which particular folding mode you like from vim, but the
folding-mode link takes you to a minor mode page that describes how to
setup emacs to use something very much akin to vim's marker folding
mode.
Anyways, check 'em out, it looks like there are a number of options.
Looks like the questions about vim code folding were answered - as for
emacs, I was able to find something the other day to do what I needed to
do. I like indentation based code folding as opposed to mark based.
So, I made my searches a little more specific in regards to indentation
based folding. I found something geared for python that someone put into
their .emacs file and just placed it in mine, but adapted for Ruby. (There
wasn't much adaptation to do)
I was just going to post about this very technique, so just for completeness
and to benefit future readers. Here is a very simple way to get some folding
(or outlining) in emacs for ruby
Adding this to my .emacs
;;; enables outlining for ruby
;;; You may also want to bind hide-body, hide-subtree, show-substree,
;;; show-all, show-children, ... to some keys easy folding and unfolding
(add-hook 'ruby-mode-hook
'(lambda ()
(outline-minor-mode)
(setq outline-regexp " *\\(def \\|class\\|module\\)")))
This adds the outline-minor-mode to your ruby buffers. You will also most
likely want to bind some hide and show functions to appropriate keys if you
don't like the defaults (or they conflict with others).
hide-body, hide-subtree, show-subtree, show-all, show-children and the other
hide* and show* methods are what you will use to collapse or expand, so you
may want to bind them to convenient keys if the default bindings don't work
for you.
Blessings,
Jeff
