ERB trim_mode '<>' is not working as expected

Ruby

Ruby code :

require ‘erb’

class Animal
def add(name)
(@animals ||= []) << name
end
def generate_template
erb = ERB.new(File.read("#{dir}/test.rhtml"),0,’<>’)
erb.result(binding)
end
end

animal = Animal.new
animal.add(‘dog’)
animal.add(‘cat’)
animal.add(‘monkey’)
puts animal.generate_template

#.rhtml file

hello
    <% @animals.each do |item| %>
  • <%= item %>
    • <% end %>

    #output

    hello 
    <li> dog </li>

    <li> cat </li>

    <li> monkey </li>

Note : In the output you can see, none of the new line has been
suppressed. but I passed trim_mode as ‘<>’.

I passed '<>' to suppress the new lines, but I couldn’t. What wrong I
did ?

Expected :

hello
  • dog
  • cat
  • monkey

    The documentation for the trim mode ‘<>’ says “omit newline for lines
    starting with <% and ending in %>”, and the animals.each line and its
    end have leading spaces before the <%, so the line doesn’t start with <%

    • it starts with spaces (or some other white space character).

    You can either change the template so the lines for which you want to
    suppress newlines start and end with the <% and %>:

    hello
      <% @animals.each do |item| %>
    • <%= item %>
      • <% end %>

      Or you can use the trim mode of ‘>’ which lets you have leading spaces
      because it checks only for the line ending with %>. This mode will let
      you indent your erb “nicely”.

      I think there is a

    tag missing too…

    Hope this helps,

    Read the doc wrongly. I thought doc is saying inside <% … %>.

    Thank you Mike!
