Wish list: webrick server with cgi test file

ruby-talk
1

Anyone has a webrick server which works with a cgi test file, to share
with me?
Hopefully, not all webrick users are at the rails conference!

I have tried various combinations with various errors. Here is the
latest attempt
using the info on this page for server and test file
http://microjet.ath.cx/webrickguide/html/CGIHandler.html
----------------->
require 'webrick'

include WEBrick # let's import the namespace so
                   # I don't have to keep typing
                   # WEBrick:: in this documentation.

def start_webrick(config = {})
  # always listen on port 8080
  config.update(:Port => 8080)
  server = HTTPServer.new(config)
  yield server if block_given?
  ['INT', 'TERM'].each {|signal|
    trap(signal) {server.shutdown}
  }
  server.start

end

start_webrick {|server|
  cgi_dir = '/library/webserver/documents/ruby/cgi-bin'
  server.mount('/cgi-bin', HTTPServlet::FileHandler, cgi_dir,
    {:FancyIndexing=>true})
}

with the test file in cgi-bin, test2.cgi, executable
#!/usr/bin/env ruby
print "Content-type: text/plain\r\n\r\n"
ENV.keys.sort.each{|k| puts "#{k} ==> #{ENV[k]}"}

I get an error message.
env: ruby: No such file or directory
With other attempts I get other errors.

I started with the webserver on this page
http://microjet.ath.cx/webrickguide/html/What_is_WEBrick.html
---------------->
require 'webrick'

include WEBrick # let's import the namespace so
                   # I don't have to keep typing
                   # WEBrick:: in this documentation.

def start_webrick(config = {})
  # always listen on port 8080
  config.update(:Port => 8080)
  server = HTTPServer.new(config)
  yield server if block_given?
  ['INT', 'TERM'].each {|signal|
    trap(signal) {server.shutdown}
  }
  server.start

end

start_webrick(:DocumentRoot =>
'/library/webserver/documents/ruby/cgi-bin')

···

----------------------
it serves a hello.html file in cgi-bin directory fine.
----------------->
<!DOCTYPE html PUBLIC "-//IETF//DTD HTML 2.0//EN">
<HTML>
   <HEAD>
      <TITLE>
         A Small Hello
      </TITLE>
   </HEAD>
<BODY>
   <H1>Hi</H1>
   <P>This is very minimal "hello world" HTML document.</P>
</BODY>
</HTML>

This particular error has nothing to do with webrick. What is happening is that the /usr/bin/env command cannot find ruby in it's path. The first thing to try would be to replace

#!/usr/bin/env ruby

With

#!/usr/bin/ruby

Or where ever your ruby image is (try 'which ruby' to find out).

What is a webrick servlet?
http://microjet.ath.cx/webrickguide/html/CGIHandler.html

I can serve my cgi test file with a webrick server with or without
servermount...
why does this page seem to say cgi needs a cgi handler?
Are the two servers different?

first server
--------------->
require 'webrick'

include WEBrick # let's import the namespace so
                   # I don't have to keep typing
                   # WEBrick:: in this documentation.

def start_webrick(config = {})
  # always listen on port 8080
  config.update(:Port => 8080)
  server = HTTPServer.new(config)
  yield server if block_given?
  ['INT', 'TERM'].each {|signal|
    trap(signal) {server.shutdown}
  }
  server.start

end

start_webrick(:DocumentRoot =>
'/library/webserver/documents/ruby/cgi-bin')

second server
------------------>
require 'webrick'

include WEBrick # let's import the namespace so
                   # I don't have to keep typing
                   # WEBrick:: in this documentation.

def start_webrick(config = {})
  # always listen on port 8080
  config.update(:Port => 8080)
  server = HTTPServer.new(config)
  yield server if block_given?
  ['INT', 'TERM'].each {|signal|
    trap(signal) {server.shutdown}
  }
  server.start

end

start_webrick {|server|
  cgi_dir = '/library/webserver/documents/ruby/cgi-bin'
  server.mount('/cgi-bin', HTTPServlet::FileHandler, cgi_dir,
    {:FancyIndexing=>true})
}

Thank you, changing that line did fix this example.
And with this line my other test cgi script works too. Thank you!!!

start_webrick(:DocumentRoot => '/var/www')

is functionally similar to:

start_webrick {|server|
doc_root = ='/var/www'
server.mount("/" HTTPServlet::FileHandler doc_root,
{:FancyIndexing=>true})
}
