Roda :wrap_link_to plugin proposal

[v-kolesnikov]

Hi!

I just resolved the issue in my project: wrapping each table row column to a link.

TL;DR: You are unable to make a table row as a single link item. You must wrap each column to the same link tag.
To simplify the code I wrote a function that uses combination of capture_erb, inject_erb and link_to plugins.

Maybe it could be useful and would save time for someone.

# frozen-string-literal: true

class Roda
  module RodaPlugins
    # The wrap_link_to plugin adds the +wrap_link_to+ instance method, which can be used for
    # constructing HTML links (+a+ tag with +href+ attribute).
    #
    # The simplest usage of +wrap_link_to+ is passing the location to link to as strings and
    # the body as ERB inside a block:
    #
    #   <% wrap_link_to("/foo") do %>
    #     <div class="a">Hi!</div>
    #   <% end %>
    #
    #   will produce HTML:
    #
    #   <a href="/foo">
    #     <div class="a>Hi!></div>
    #   </a>
    #
    # The wrap_link_to plugin depends on the link_to plugin and pass <tt>wrap_link_to</tt> params
    # to <tt>link_to</tt>.
    module WrapLinkTo
      def self.load_dependencies(app)
        app.plugin :capture_erb
        app.plugin :inject_erb
        app.plugin :link_to
      end

      module InstanceMethods
        # Return a string with an HTML +a+ tag with an +href+ attribute. See WrapLinkTo
        # module documentation for details.
        def wrap_link_to(href, attributes=OPTS)
          body = capture_erb { yield }
          inject_erb link_to(body, href, attributes)
        end
      end
    end

    register_plugin(:wrap_link_to, WrapLinkTo)
  end
end
