Folding editor for ruby code browsing

[Andrew Walrond]

I need to fold the code so that I can get a handle on the overall structure;
basically to tidy up and and move whole public methods into protected or
private sections, that sort of thing.

I've tried browsing the code in Kate (xemacs is my usual home) which supports
folding of ruby code. But it's folding is very buggy and I seem to lose whole
portions of a file into a fold without warning. I can't find any good folding
solutions for xemacs. What about vim, or other open source editors (for
linux)?

Recommendations?

Vim is excellent at folding (along with pretty much everything else).
You can fold by any number of methods, including indent, marker,
expression, syntax, diff-style, or even manual... Give it a shot if
you're not too die-hard with emacs.

Try the open source FreeRIDE IDE:

http://freeride.rubyforge.org/

It not only does code folding, but also has a source browser - a
clickable tree control that let's you see and navigate your ruby code by
its structure (module/class/method). It also has interactive Ruby
documentation.

Best of all, it written entirely in Ruby and is open source!

jEdit with the Ruby plug in does this quite well. There's other folding
options like by-indentation as well.

SciTE does folding quite well (especially if you get the more rubyish
lexers, the old one did some strange pythonic things).

Vim fell at the first hurdle; syntax colouring/highlighting
It seems unhappy with IO#<< unless I put some spaces around it; Try the
attached file.

I have downloaded the latest syntax/ruby.vim file, but no change.

Haven't tried folding yet

attached file.

The syntax highlighting engine parses the line
f<<stdin
as the beginning of a Here Document. This would go away if you
put a space after the << (makes the code more readable too IMO).

As a fix (especially if you don't use Here Documents anyway) you
can comment out the lines in the Here Document section of the
ruby.vim file; actually, commenting out only the first line there,
(the one containing the expression '<<\z' (without the quotes))
should work too.

HTH,

Michael

What version of Kate/KDE are you using?
If you can show me specific code snippets for which syntax highlighting or
code folding fails, I can probably correct them.

I'll mail you the offending file off-list (because its too big for the ML, not

Any online places that discuss vim folding? Or general vim tips, for
that matter?

Emacs can do this just as well

Thaks for the pointer, but I was really looking for something that doesn't
involve adding any special 'fold mark' comments into the code.

Hmm, i was trying to get it folding on def/end lines, but it's not going
along with my plan, there must be a simple way to do this, have you
tried cedet/ecb? It wouldn't suprise me if there is folding stuff in
there, although it might take a bit of lisping to setup for ruby.

I got it going with cedet/ecb, i simply installed them both (to
/usr/share/emacs/site-lisp/) and added this: to my .emacs

;; Emacs Code Browser / CEDET


(load-file "/usr/share/emacs/site-lisp/cedet/common/cedet.el")
(semantic-load-enable-code-helpers)

(add-to-list 'load-path
"/usr/share/emacs/site-lisp/ecb")

(load-file "/usr/share/emacs/site-lisp/ecb/ecb.el")

(require 'ecb)

Then after emacs has started type M-x ecb-activate, you should have a
window on the left hand side which shows a list
of classes(and methods), buffers, source files in current tree and a
directory view. I can't find folding support but i can't imagine how
you'd need it with that list (third button click also takes you to each
part)If you're still nonplussed i'll send you a screenshot if you like.
Hope this helps.

No - I haven't tried that. I'll give it a blast. Thanks!

You can tell emacs to hide anything that's indented farther than X characters
in any buffer. set-selective-display (C-x $) hides lines with indentation >
count, or shows everything if you don't give it a count. See the docs for that
function for more information.

After some playing around with various of the more graphically
oriented IDEs, kdevelop is currently my favourite for Linux use.
I have never been much for VIm or Emacs, although I should
probably learn them, huh?

As a matter of principle I would also like to plug Mondrian,
a pure-ruby IDE with a bunch of promise (albeit no folding).

Only a cloning machine, or brain augmentation would enable that.

didn't have a backup of the ML - doh!).

But I climbed back on, charged around aintree and won the national by a
nose...

I spent a few hours feeling like somebody had chopped my arms off, but now I'm
getting to grips with vims modal system. I _really_ like vim's syntax based
folding mechanism (set foldmethod=syntax).

For that feature alone, I think vim might just become my editor of choice.

Graphical only editors and IDEs are great, but a significant amount of my work
is done via ssh, so I really need an editor that works well in both
environments.

Vim is *awesome* at folding. And *awesome* at everything else I have tried so
far. I wish I had spent a day learning vim _years_ ago.

Its a bit like snow-boarding; I put off learning for ages (because I didn't
want to waste a holiday) But I haven't put on skis since I tried it

_Sincere_ thanks for the recommendation!
