String literals

ruby-talk
1

Hello,

I’m not very experienced in ruby, and can’t found how to write long
multiline string literals without variable expanding. I know that I
can use:

"literal"
'literal'
%Q{literal}
%q{litaral}
var = <<EOF
...
EOF

but the last one, multiline, is there only in “” (expanding) variant.
Is there unexpanding (’’) variant of the multiline string literal.

but the last one, multiline, is there only in "" (expanding) variant.
Is there unexpanding ('') variant of the multiline string literal.

Something like this ? (see '' around EOF)

pigeon% cat b.rb
#!/usr/bin/ruby
$a = 12
var = <<'EOF'
variable #$a
EOF
p var
pigeon%

pigeon% b.rb
"variable #$a\n"
pigeon%

str = 'First line. ’
+ ‘Second line.’
+ ‘Third line.’

Hope this helps.

Don’t forget that with %Q and %q you can use any non-alphanum char as the start-end delimiter %^^ # => ""

Or even:
% cat strings.rb
$a = 12
var = ’
variable #$a
Ruby Strings are multi-line by default.
’
p var

% ruby strings.rb
“\nvariable #$a\nRuby Strings are multi-line by default.\n”
