How to write ruby in multiple lines

[anakintang]

All,

How can I write "s = s1 + s2 + s3" in multiple lines like below:

s= s1
+ s2
+ s3

Thanks

You can't.

You can do it differently, though:

s = s1 +
s2 +
s3

If you have an operator at the end of the line, needing operands, Ruby
keeps reading.

-s

You actually can with a trailing backslash:

% irb
irb(main):001:0> s1 = s2 = s3 = 1
=> 1
irb(main):002:0> s = s1 \
irb(main):003:0* + s2 \
irb(main):004:0* + s3
=> 3

Like that
s = s1 +
s2 +
s3

or

s = s1 \
+ s2 \
+ s3

AFAIK, the first form is more in use than the second.

s2 +
s3

or

s = s1 \
+ s2 \
+ s3

AFAIK, the first form is more in use than the second.

In the example given, which is obviously contrived, it makes
little difference. But when s1, s2, and s3 are longer
expressions, I find that the second version is more readily
grokked.

Without looking at the end of a line, you can tell that it is a
continuation of a previous line, and while at the end of a line
to can tell that it is continued.

That's my $0.02
