This example is from the documentation for ERB (with a small error corrected: added argument binding to line 36):
$ cat -n t.rb
1 require "erb"
2
3 # Create template.
4 template = %q{
5 From: James Edward Gray II
6 To: <%= to %>
7 Subject: Addressing Needs
8
9 <%= to[/\w+/] %>:
10
11 Just wanted to send a quick note assuring that your needs are being
12 addressed.
13
14 I want you to know that my team will keep working on the issues,
15 especially:
16
17 <%# ignore numerous minor requests -- focus on priorities %>
18 % priorities.each do |priority|
19 * <%= priority %>
20 % end
21
22 Thanks for your patience.

25 }.gsub(/^ /, '')
26
27 message = ERB.new(template, trim_mode: "%<>")
28
29 # Set up template data.
30 to = "Community Spokesman "
31 priorities = [ "Run Ruby Quiz",
32 "Document Modules",
33 "Answer Questions on Ruby Talk" ]
34
35 # Produce result.
36 email = message.result(binding)
37 puts email
The embedded scriptlet at lines 16-18 uses a shorthand notation (and works!):
18 % priorities.each do |priority|
19 * <%= priority %>
20 % end
Its longhand form would be:
18 <% priorities.each do |priority| %>
19 * <%= priority %>
20 <% end %>
My problem: I have been unable to craft a small shorthand example
that actually works.
Any help appreciated!
