Rails - Nov 2005 - Ruby coding question

I have a question about ruby code delimiters.

This code block:

<% end -%>

What does the "-" before the ending delimiter signify? My code errored
out, I thought those were
misprints or something in the book, but added them and it works. I
don''t recall seeing that in the
Ruby appendix, and I''ve never seen this convention before (like with
JSP or ASP).

TIA

Simply prunes the \n after ''end''.

Thanks - Had I literally read the next line.. :/ I would have known that. Nice
feature though!

Tom:

the final -%> differs from %> in that if there is no text produced  
between the delimiters then it takes no space on the page. I believe  
the standard delimiter %> would take up some space whether or not it  
needed to.  A good example of when this may be useful (I used it the  
other day) is if you were making invoices and had something like

<% org.company_name %>   #no need for fancy delimiter as all  
companies will have names
<% org.address1 %>              #as above
<% org.address2 -%>             #note fancy delimiter because many  
companies don''t have an address2 and we don''t want a blank
line
appearing in the address.
