Is it possible add a transformation without any associated attribute?

[andrewaguiar]

Is it possible add a transformation without any associated attribute? For instance, I would like to add a transformation to every svg without a specific attribute eg:

InlineSvg.configure do |config|
  # Is it possible
  config.add_custom_transformation(transform: SetFocusableToFalseTransform)
end

and the transformation

class SetFocusableToFalseTransform < InlineSvg::CustomTransformation
  def transform(doc)
    svg = doc.at_css('svg')
    svg['focusable'] = 'false'
    doc
  end
end

Thanks

@andrewaguiar No, sorry. It's not possible, but I'm open to changing the gem to accommodate "static" custom transformations.

As a workaround I suggest rewriting your transformation like this:

class SetFocusableTransform < InlineSvg::CustomTransformation
  def transform(doc)
    svg = doc.at_css('svg')
    svg['focusable'] = !!value.to_s
    doc
  end
end

Configure it like this:

InlineSvg.configure do |config|
  config.add_custom_transformation(attribute: :focusable, transform: SetFocusableToFalseTransform)
end

And use it like this:

inline_svg('some-document.svg', focusable: true)
inline_svg('some-document.svg', focusable: false)

@jamesmartin I sent a PR with an implementation of somthing that can be used to do this #37

Thanks
