Subject: Re: eRuby (making it work)

After much time and numereous attempts, I did the following to get both 
Ruby and eRuby working for me. 

What follows assumes telnet access and a directory (cgi-bin for me) that 
is recognized by the system as an active cgi script directory.

Start description ==============================
1.  installed Ruby using the -prefix=/my/path/to/ruby directory option
    If you need to, use ./configure --help to review options.

2.  installed eRuby 
    If necessary, change the shebang #! line in configure.rb
    to point to the location of ruby, i.e.,
    #!/my/path/to/ruby

3.  created a .htaccess file in my "webdocuments" directory that contained

AddHandler cgi-script  rb rbx  

AddHandler application/x-httpd-eruby .rhtml
Action application/x-httpd-eruby /cgi-bin/eruby

4.  moved eRuby to my cgi-bin directory

5.  created GetEnv.rhtml containing:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<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>

6.  created testRuby.rbx containing:
#!/my/path/to/ruby 
# This is a working ruby script running ruby script with 
# extension .rb or .rbx
# If the key for ENV does not exist, then ruby returns nil.
# It requires the following modification to .htaccess in www
# AddHandler cgi-script rb rbx
#

require 'date'
print "Content-type: text/html\n\n"
d = Date.new(2000, 3, 31)
print $:,'</p>'
print ENV['RUBYPATH'],'</br>'
print [d.year, d.yday, d.wday]
print "this is a test.", ENV['PATH'], "prefix= ",ENV['prefix'],"<br>"
  names = ["john", "mary", "", 4]
  data = [1, 2, 3, 4]
       data.each do  |i |
       print i, "    ", names[i-1],"<br>"
       end
print "<h1>Environment variables</h1><table>" 
ENV.keys.sort.each do |key|
print "<tr><th>",key,"</th><td>", ENV[key], "</td>"
print "</tr>"
end
print "</table>"

7. Ran GetEnv.rhtml and testRuby.rbx

8. They worked.  
   WOW! EXCITEMENT! 
   PHYSICAL EXPRESSIONS OF JOY! 
   GREAT SENSE OF SATISFACTION! YES! WELL DONE!

9. Hope you have the same result -- a sense of accomplishment
   and the joy of working with Ruby and eRuby.
End description =============================
