There seems to be some issue with the binding in ERB, any ideas?
(erb):16: undefined local variable or method `priority' for main:Object
(NameError)
from d:/utils/ruby/lib/ruby/1.8/erb.rb:739:in `value'
from d:/utils/ruby/lib/ruby/1.8/erb.rb:739:in `result'
from testerb.rb:36
is what I get when I try to run the following, taken from
http://www.ruby-doc.org/stdlib/libdoc/erb/rdoc/
require "erb"
# Create template.
template = %q{

Just wanted to send a quick note assuring that your needs are being

I want you to know that my team will keep working on the issues,
especially:
<%# ignore numerous minor requests -- focus on priorities %>
% priorities.each do |priority|

% end
Thanks for your patience.

% priorities.each do |priority|
This line -^ is just some other output of ERB - there are no '<%' ... '%>' pairs...
* <%= priority %>
% end
Would this do it?
<% priorities.each do |priority| %>
* <%= priority %>
<% end %>
Hope that helped
Happy rubying

Works fine here. I pulled the code right out of your email and pasted it into a file:
Neo:~/Desktop$ ruby erb_test.rb

I'm not sure what's going on.

Not, according to the rdoc, when '%' is passed to ERB.new.

pasted it into a file:
Hmm, it would be interesting if a few others could try it, it may be
something to do with my specific ruby environment.
D:\lcs\source\ruby>ruby -v

Works for me. Sorry!
C:\Documents and Settings\dlm>ruby -v

All I did was type "ruby", hit Enter, pasted in the code, hit Enter, hit Ctrl-D, and hit Enter.
