erb how to loop on array

I can't simply loop on an array with ruby erb template system...

here is my template:

<% ['foo', 'bar'].each do |val| -%>
<%= val %>
<% end -%>

Here is the command line and the result

erb test.erb
/usr/share/rvm/rubies/ruby-2.4.1/lib/ruby/2.4.0/erb.rb:896:in `eval': test.erb:1: syntax error, unexpected ';' (SyntaxError)
'foo', 'bar'].each do |val| -; _erbout.concat "\n"
                              ^
test.erb:3: syntax error, unexpected ';'
;  end -; _erbout.concat "\n"
         ^
        from /usr/share/rvm/rubies/ruby-2.4.1/lib/ruby/2.4.0/erb.rb:896:in `result'
        from /usr/share/rvm/rubies/ruby-2.4.1/lib/ruby/2.4.0/erb.rb:878:in `run'
        from /usr/share/rvm/rubies/ruby-2.4.1/bin/erb:149:in `run'
        from /usr/share/rvm/rubies/ruby-2.4.1/bin/erb:170:in `<main>'

What is wrong with this really simple example?

Disclaimer: I am a ruby and erb noob ^^

Solution

  • You're not supposed to have those "-" at the end before the "%".

    <% ['foo', 'bar'].each do |val| %>
    <%= val %>
<% end %>

    This should work.
