What is the built-in ruby ​​limiter? -%>

Question

" -%> " appears in some code in the tutorial that I am doing as a delimiter of some built-in ruby, for example:

 <% 5.times do |i| -%> <%= thumbnail_tag slideshow.slides[i] %> <% end -%> 

What does it mean? There is nothing in the book (Rails Up and Running)

Answer 1

The ERB template language supports <%- and -%> in addition to Ruby code separators <% and %> .

Add a minus to the inside of the space separator from HTML next to the outside of the separator.

Answer 2

In ERB, it removes any new line that follows from the output.
