Subject: ruby-mode indent frustration

-----BEGIN PGP SIGNED MESSAGE-----

Hello,

I am used to c-mode indents and I find ruby-mode.el's indenting 
frustrating.  Has anyone configured, modified, or rewritten 
ruby-mode.el to indent statements in a way more like c-mode does?  I 
found Jim Weirich's code to properly reformat comments without 
reformatting code as c-mode does using M-q on rubygarden.

The code below includes some examples of lines I would like indented 
differently, though the expressions are short.   Because ruby's parser 
considers any statement that could be finished on a line finished, 
there are only a few ways to break up complex statements.  Operators 
like "||", "+", and "%" all cause ruby-mode to indent the next line 
directly beneath where it would be anyway -- making it useless to try 
to split these expressions across lines.  Placing a {} block as a 
parameter to a function somehow causes the indenting to 
counter-intuitively start over at the left.  And the "?" conditional 
assignment operator gets no indenting for the next line at all.

# the following statement should line up false beneath true,
# as c-mode does.
if ( true ||
            false ) then

   # the following statement should line up "baz" either
   # under "foo" or ruby-indent from the left edge.
   puts "foo bar %s" %
                      "baz"
   # same as above.
   puts "Foo" +
               "Bar"

   # the second line should be indented somehow.
   puts use_celsius ?
   100 : 212;

   # the second line should be indented somehow,
   # preferably at least as far in as the "("
   puts( [ "a", "b", "c" ].map { |c|
   c + c }.join()
         )

   # are fine:
   puts "Foo",
        "Bar"
   puts "foo bar %s" % [
     "baz"
   ]
end

I don't know how to configure or improve ruby-mode.el to handle these 
statements, and I realize c-mode has it easy since all it has to do is 
wait for semicolons, but I think improving the formatting will make 
code more readable.

thoughts?
