Specify options for a filter in ruby HAML

filter, haml, indentation, javascript, ruby

Solution

There is no way to pass extra attributes to the `:javascript` filter like this. You could however use a `:plain` filter along with a normal `script` tag to allow indenting your javascript code:

%script{:'data-turbolinks-eval' => 'false', :foo => 'bar'}
  :plain
    if(someCondition()) {
      doSomething();
    }

produces:

<script data-turbolinks-eval='false' foo='bar'>
  if(someCondition()) {
    doSomething();
  }
</script>

Problem

Is there any way to add options (HTML attributes) to HAML filters? I wanted to do something like this : ``` :javascript{:'data-turbolinks-eval' => 'false', :foo => 'bar'} if(someCondition){ doSomething(); } ``` And the result would be : ``` <script 'data-turbolinks-eval'='false' 'foo'='bar'> if(someCondition){ doSomething(); } </script> ``` The closest I could get is : ``` %script{:'data-turbolinks-eval' => 'false', :foo => 'bar'} if(someCondition){ doSomething(); } ``` The drawback is that you can't indent your JS in HAML unless you're using the :javascript filter. It's ok for a few lines, but it can get messy quickly. I'm well aware that in most cases if you end up with a complex script in a HAML template, it means you're doing something wrong and that's not the answer I'm looking for.
