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?
