Ruby Hash Fetch Issue with Sass

Question

I'm at a loss. Hoping somebody with more Ruby experience will tell me what is going on.

I'm calling a custom Sass function from my stylesheet like so:

$color: user_var('color')

The custom function looks like this:

module Sass::Script::Functions
  def user_var(param_name)
    puts options[:custom]
    puts options[:custom].fetch('color')
    puts options[:custom].fetch(param_name)
  end
end

The result of puts options[:custom] (as expected) is this:

{"color"=>#eeeeee, "header"=>20px}

The result of puts options[:custom].fetch('color') is #eeeeee

BUT... the result of puts options[:custom].fetch(param_name) results in a "key not found: 'color' (KeyError)".

Completely baffled here.

Answer 1

my guess is that param_name is a symbol and the color key in the options hash is defined as a string.

this should work.

options[:custom].fetch("#{param_name}")
