Question

I have a file in my rails 3.1 project called: foo.js.coffee.erb

console.log <?= 1+1 ?>

This causes:

throw Error("ExecJS::ProgramError: Error: Parse error on line 1: Unexpected 'COMPOUND_ASSIGN'\n  (in /Users/trafnar/Sites/imagesnap/app/assets/javascripts/tiles.js.coffee.erb)")

Clearly the ERB is tripping it up. I thought Rails 3.1 allowed the use of an ERB preprocessor before coffeescript, why might this be failing?

Answer 1

Are you sure you have your delimiters right? I’d expect to see:

console.log <%= 1+1 %>

in an .erb file.
