Question

I have a string like so string1:

Hello World, join my game:

I would like to make string1 become:

Hello World, join my game:

http://game.com/url

How can I append a carriage return with ruby and then a link from another variable?

THanks

Answer 1

It really depends on what you are outputting to.

$STDOUT:

puts "Hello\n\n#{myURL}"

or

puts "Hello"
puts
puts myURL

or

puts <<EOF
Hello

#{myURL}
EOF

If you are outputting this in an html.erb or .rhtml document:

<%= "Hello<br /><br />#{myURL}" %> # or link_to helper

If you already have a string like string1 then you can append to it using either += or <<:

string1  = "Hello world, join my game:"
myUrl    = "http://example.com"
string1 += "\n\n#{myUrl}"

or:

string1 = "Hello world, join my game:"
myUrl   = "http://example.com"
string +=<<EOF

#{myUrl}
Here's some other details
EOF
