respond_with tried to require every engine Tilt knows about

[ericroberts]

When it does Tilt[engine] in template_for, it tries to require the engine, but most of them are not installed.

Downgrading tilt to 1.4 makes it work for now.

@ericroberts Can you provide a reproducible script?

I just came across the same issue, template_for trying to require all engines.

Worked around it by forcing it to only search the engines I'm using:

settings.template_engines[:all] = [:erb]

Using sinatra and contrib 1.4.7 with tilt 2.0.5. Triggered by:

require 'sinatra'
require 'sinatra/respond_with'
get '/' do
  respond_with :index
end

curl -v -H "Accept: text/html" 'http://localhost:4567/'

Looks like this bit of code in respond_with.rb:

          # not exactly like Tilt[engine], but does not trigger a require
          if Tilt.respond_to?(:mappings)
            klass = Tilt.mappings[Tilt.normalize(engine)].first
          else
            klass = Tilt[engine]
          end

The current tilt doesn't seem to have a mappings or normalize method anymore.

Could someone with context on this open an issue on tilt to see if there is a workaround/alternative?

Go ahead and assign it to me if you'd like, I'll see what I can work out with them.
