Script/plugin discover errors

Rails Engines
1

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

from
c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_suppo
rt/dependencies.rb:147:in `require’
from script/plugin:3

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,

Scott T.

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: Edit

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='"['"]/ 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.
