-%> strips the trailing whitespace and newline.

<%- strips leading whitespace but not newline.

So   <% if foo %>     bar   <% end %> generates " \n bar\n \n" whereas   <%- if foo -%>     bar   <%- end -%> generates " bar\n"

This is especially useful in templates for plain-text emails.

Thanks Jeremy! So it has no effect in html.erb files, i.e., in the views, right? I tested here and nothing changed.

Here is a page that maybe can help someone: http://springyweb.com/documents/1
