Question

Ok, seems i’ll go with Espresso.
It is really clean and easy.

Are there built-in support for Slim?

Can not find anywhere in docs how to use it.

Trying this:

require 'e'
require 'slim'

class Blog < E

  engine :Slim
  # etc.
end

and getting a weird error about no Slim engine found, though i loaded it.

Answer 1

The issue here is that Espresso using Tilt for rendering.

And Tilt has no built-in support for Slim.

However, Slim does have built-in support for Tilt 🙂

All you have to do is to register a new Tilt template:

require 'slim'

Tilt::SlimTemplate = Slim::Template

That’s it. Now you can use it like this:

class Blog < E

  engine :Slim
  engine_ext :slim
  # etc.
end

Please note engine_ext :slim – it will inform Espresso about templates extension.

Most likely you’ll name your templates like template-name.slim
