Liquid is a ruby library for rendering safe templates which cannot affect the security of the server they are rendered on. Liquid does NOT allow ruby code inside the markup.

[1] pry(main)> require 'liquid'
=> true
[2] pry(main)> @template = Liquid::Template.parse("hi {{name}}") 
=> #<Liquid::Template:0x007f820f8206e8
    ["hi ",
[3] pry(main)> @template.render('name' => 'tobi')
=> "hi tobi"

Filters can be applied on output tags:

[~/rubytesting/liquid]$ cat filters.rb 
require 'liquid'

template = <<-'EOT'
  Hello {{ 'tobi' | upcase }}
  Hello 'tobi' has {{ 'tobi' | size }} letters!
  Today is {{ 'now' | date: "%A %dth of %B %Y" }}

@template = Liquid::Template.parse(template)

puts @template.render()
[~/rubytesting/liquid]$ ruby filters.rb 
  Hello TOBI
  Hello 'tobi' has 4 letters!
  Today is Saturday 11th of January 2014

You can’t give access to objects of arbitrary classes to end users. Due security concerns, only String, Numeric, Hash, Array, Proc, Boolean or Liquid::Drop are allowed by default. The final value rendered in the template is the result of sending to_liquid message to the resolved object. Liquid extends some of the ruby standard classes with that method.

[~/rubytesting/liquid]$ cat if.rb
require 'liquid'

User =
user ='Juana')
def user.to_liquid
    'name' =>,
    'age'  => 9

template = <<-'EOT'
  {% if user %}
    Hello {{}} is {{user.age}} years old
  {% endif %}

@template = Liquid::Template.parse(template)
puts @template.render("user" => user)

[~/rubytesting/liquid]$ ruby if.rb 
    Hello Juana is 9 years old

Creating filters is very easy. Basically, they are just methods which take one parameter and return a modified string. You can use your own filters by passing an array of modules to the render call like this: @template.render(assigns, [MyTextFilters, MyDateFilters]).

Alternatively, you can register your filters globally:

[~/rubytesting/liquid]$ cat create_filter.rb 
require 'liquid'
require 'redcloth'

module TextFilter
  def textilize input


t = <<"EOI"
{{ 'Do not *ever* pull this _lever_.' | textilize}}
template = Liquid::Template.parse t
puts template.render()

[~/rubytesting/liquid]$ ruby create_filter.rb 
<p>Do not <strong>ever</strong> pull this <em>lever</em>.</p>
