Rails - Aug 2006 - The latest & greatest Routing (Rails Edge 4611)

Got a quick question regarding the latest and greatest:

module ActionController
  module Routing
    SEPARATORS = %w( / ; . , ? )

Why is period (.) one of the separators? As it stands, the new routing 
code doesn''t recognize ''file.ext'' as the last
component of a URL, which
is sometimes defaulted to nil. See the generated code below.

I don''t know everything about URL encoding, but it seems that period 
isn''t one of should-be-escaped characters in a URL.

Thanks in advance!

Doug.

An extension is the natural way to specify a resource''s mime type:
   /people/1.xml

So it''s now parameterizable:
   map.connect ''/:controller/:id.:format'', :action =>  
''show'', :require => { :method => :get }

   class PeopleController ..
     def show
       # The :format param informs respond_to.
       respond_to do |wants|
         wants.html # renders the rhtml
         wants.xml  { render :xml => @person.to_xml }
       end
     end

   GET /people/1
   GET /people/1.html
   GET /people/1.xml

Thank you, Jeremy, for the clear explanation! Indeed, it''s quite a 
useful feature.

However, the implementation of it has introduced a problem: a URL
that''s
generated by the following route cannot be recognized by the same route.
  map.connect ''/:controller/:action/:file'', :defaults =>
(:file => nil}
Note that .:format isn''t specified, and then the file segment contains
a
dot, but url_for doesn''t escape the dot.

A bug?
