I came across this in api.rubyonrails.org and am wondering if it is a
typo or an undocumented feature. Can someone explain?
<% form_tag '/posts' do -%>
<div><%= submit_tag 'Save' %></div>
<% end -%>
In particular, I refer to the closing Ruby delimiter '-%>' syntax that
is repeated twice in this example.
Pardon me if this is obvious. I am still new to Ruby.
