Long quotes on multiple lines

Is there an idiomatic way to continue a long quote on a separate line,
or should I just do:

“If you need help,” +
" please dial the operator"

Hmm, I don’t think you can…

if you do (which you can)

“If you need help
please dial the operator”

you’ll get ‘\n’ sneaked in there…

I think that using ‘+’ is the only way. Now the question is if that
affects performance at all… I wouldn’t know.

At a guess, I would say that using + means it has to go through
String#+. If you write something like

class String
alias old_plus :+
def + other
puts "adding strings “#{other}”
old_plus other
end
end

On the other hand, if you use a lexical construct like

“asdf asdf”
“asdf asdf”

Then the compiler probably does (or at least can do) literal string
concatenation at parse time.

ah ok, so this is the answer Robert was looking for:

“asdf asdf”
“asdf asdf”

I didn’t know how to do this either. Now I know. Cool

“one
two
three”
=> “one two three”

Alternative to escaping new lines is replacement:

irb(main):004:0> s=“foo
irb(main):005:0” bar
irb(main):006:0" baz".gsub! “\n”, ’ ’
=> “foo bar baz”
irb(main):007:0> s
=> “foo bar baz”

Of course, this is less efficient because it’s done at runtime - but
might be ok for constants.

This also works with heredocs.

Is this deprecated and planned for removal at some point? I seem to
recall so.

Also, if you like something fancy:

require 'facet/string/margin'

x = %Q{
      | This
      |     is
      |       margin controlled!
      }.margin

string literal concatenation

puts “If you need help,”
" please dial the operator"

escaping new lines

puts “If you need help,

ditto, with here doc

puts <<EOS

Maybe in the future, but it’s not deprecated nor planned yet
right now, although Matz has mentioned about it somewhere.

And, the last one included a new line at the end.
Instead, another one:

empty expression interpolation

p “If you need help,#{
} please dial the operator”
