question for newbie

[Nericl Lau]

a = << END_STR
This is the string
And a second line
END_STR
puts a


What does it mean?
I kept getting this error


q1.rb:1: syntax error, unexpected tLSHFT
a = << END_STR

It means that you can't have a space or it looks like you're trying to
use the "left shift" operator <<

a = <<END_STR
This is the string
And a second line
END_STR
puts a

Or using the option to allow the ending tag to be indented:

a = <<-END_STR
This is the string
And a second line
END_STR
puts a

Should do what you want.

you need to remove the space between << and END_STR for the heredoc to work

like so

here = <<EOF
I am inside
a here doc
EOF

puts here

That's called a heredoc string. See
http://www.ruby-doc.org/docs/ruby-doc-bundle/Manual/man-1.4/syntax.html#here_doc
you have an extra space between << and END_STR

try this:
a = <<END_STR
hello world
END_STR
puts a
