• $pref_url="public/client/"
  html(lang='en')
  head
  block head
  //ERROR

  //OK
  script(src=$pref_url."node_modules/systemjs/dist/system.src.js")

Could you give some more explanation and also format your example so that I can see the actual problem?

Both compile correctly for me

Alright, what you're running into is a simple escaping-problem.

Jade escapes everything by default. It doesn't help using !{$pref_url}, because the attribute value is an expression and gets escaped separately from the interpolation.

If you want it unescaped, use the following

link(rel="stylesheet", href!="#{$url_root}app.css")

That works (I tested it here)

Notice the != to define the atttribute, which tells Jade: Don't escape this attribute.

Notice that this is wanted behaviour, since it protects your site from XSS-attacks from feeding user input into Jade files (automatically, by default).

Thank you! Everything is working! Thank you for the quick response.
