Folding editor for ruby code browsing

Andrew Walrond

4/24/2005 9:46:00 PM

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.ruby...

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

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
because its confidential)

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

Emacs can do this just as well
http://www.chrislott.org/geek/emacs/n2n_foldin...
(see the customizing folding mode section)
