Defining ruby methods in template is no longer possible

[gurix]

After I had updated some bundles I was no longer be able to call methods I defined in the template using the ruby filter:

ruby: 
  def hello_world(text)
    "Hello #{text}"
  end

p= hello_world('Johny')

This code throws the following error: «undefined method `hello_world' for ...»

I fixed it by using class methods instead, but this is just an ugly hack:

ruby: 
  def self.hello_world(text)
    "Hello #{text}"
  end

p= hello_world('Johny')

I cannot see why this behaviour changed especially because I did not update slim itself. Slim version ist slim-4.0.1.
Any ideas? My guess is that it must be some gem I updated before but I cannot see what's related with slim that could cause this behaviour. There is the diff of my Gemfile.lock.

Hi,

This is due to that specific change in tilt which was released in tilt 2.0.10: rtomayko/tilt#343

You have more explanations in rtomayko/tilt#347

Hope that helps,
Joseph
