Forum: Rails Engines script/plugin discover errors

I would like to install The Ruby Engines plugin.  So, I followed the
directions at:
http://www.rails-engines.org/download

When I run script/plugin discover, I get the following:

Add http://svn.northpub.com/plugins/? [Y/n]
(eval):3:in `each': undefined method `[]' for nil:NilClass 
(NoMethodError)
       from

rt/dependencies.rb:147:in `require'

Am I missing something obvious?  Does someone know how to get around 
this?


I am running on Windows XP, wiht Subversion installed, with Ruby 1.8.4
and Rails 1.1.2.

Thanks in advance,

Someone appears to have put some junk on the wiki page that
script/plugin uses. You can install from the direct URL anyway:

  script/plugin install http://svn.rails-engines.org/plugins/engines

The bottom of the WIKI http://wiki.rubyonrails.org/rails/pages/Plugins 
has a link 'Edit' that is defined as: <a 
href="/rails/pages/plugins/versions/new">Edit</a>

The method scrape at line 654 of file 
...\ruby\lib\ruby\gems\1.8\gems\rails-1.1.6\lib\commands\plugin.rb 
detects this and passes "/rails/pages/plugins/versions/new" to the 
method below:

def extract_repository_uri(uri)
      uri.match(/(svn|https?):.*\/plugins\//i)[0]
end

But "/rails/pages/plugins/versions/new" does not start with svn or http, 
so there is no match and [0] has only nil to work with.

Changing line 659 to the following line factors in the http part and 
eliminates the problem.

if line =~ /<a[^>]*href=['"](https?[^'"]*)['"]/ or line =~ 
/(svn:\/\/[^<|\n]*)/

Of course the href gets expanded by a browser to 
http://wiki.rubyonrails.org/rails/pages/plugins/versions/new, but in 
this case we would the wiki problems by trying to edit the page. The fix 
above seems to be a better solution to me.
