difference between <%= end %> <%= end -%>

Hi,

    I am reffering to "Agile Web Development with Rails 2nd ed B1 21.pdf" As per this book,

    <% 3.downto(1) do |count| -%>     <%= count %>...<br />     <% end -%>     Merry Christmas!

    The minus sign in end will supress the newline. This is not happening in my case. I am using ruby 1.8.4 and Rails 1.2.2

What could be the reason?

The generated HTML code should look like this:

3...<br /> 2...<br /> 1...<br /> Merry Christmas!

If you leave out the minus sign, it should look like this:

3...<br /> 2...<br /> 1...<br />

Merry Christmas!

Is that what you're seeing, or are you getting something else? Note that the minus sign only suppresses the literal newline in the generated HTML code, not the <br /> tag which makes your browser display a newline when it renders the HTML.

Though I will keep the minus sign or remove it I am getting the output as:

3...<br /> 2...<br /> 1...<br /> Merry Christmas!
