How to write ruby in multiple lines

Ruby
1

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.

Like that
s = s1 +
s2 +
s3

or

s = s1
+ s2
+ s3

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

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

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
