Subject: Re: erb/apache problem

This is how I got 1.6 to work on an unamed popular (read cheap) host.

Added to .htaccess in /htdocs ....
AddHandler cgi-script .rb
Action application/x-httpd-ruby /usr/local/bin/ruby16?

AddHandler rubypage .rhtml .rtml
Action rubypage /erbrun.cgi?
.....

created erbrun.cgi, placed in /htdocs ....
#!/usr/local/bin/ruby16 -I/www/m/mysite/cgi-bin/ruby/lib/ruby/1.8
puts "Content-type: text/html\n\n"
require 'erb/erb'
fh = File.new( ENV['DOCUMENT_ROOT'] +
ARGV[0] )
eruby_script = fh.read
erb = ERb.new(eruby_script)
print erb.result( binding

 )
..... placed in /htdocs

create try.rhtml & place on server somewhere  ....
<html>
  <head>
    <title>eruby example</title>
  </head>
  <body>
    <h1>Enumeration</h1>
    <ul>
      <%(1..10).each do|i|%>
      <li>number <%=i%></li>
      <%end%>
    </ul>
    <h1>Environment variables</h1>
    <table>
      <%ENV.keys.sort.each do |key|%>
      <tr>
        <th><%=key%></th><td><%=ENV[key]%></td>
      </tr>
      <%end%>
    </table>
  </body>
</html>
..... browse to www.mysite.com/somewhere/try.rhtml and it works .

create testruby.rb somewher on the server ....
#!/usr/local/bin/ruby16
puts "Content-type: text/html\n\n"
puts "<HTML><PRE>Test\n"
print `ls -alF /usr/local/lib/ruby/1.6/`
.....

testruby.rb also works from the browser.

Hope this helps.
