it sounds need basic knowledge of how cgis work. once know find easier work sinatra, @echoback recommended, or padrino, rails, or work other languages.
this pretty basic cgi. generates simple form, along lines of talking about, walks through environment table passed ruby web server, sorts keys, , outputs table in sorted order. of fields directly apply either web server itself, or cgi, such query sent browser, along headers sent server saying capabilities are:
#!/usr/bin/env ruby puts "content-type: text/html" puts puts "<html><head><style type='text/css'>body{font-family: monospace;}</style></head><body>" puts "<form name='foo' action='test_cgi.rb'>" puts "<input type='textinput' name='inputbox'></input><br />" puts "<textarea name='textareabox'></textarea><br />" puts "<input type='submit'></input>" puts "</form>" puts "<h4>environment:</h4>" puts "<table>" env.keys.sort.each |k| puts "<tr><td>#{k}</td><td>#{env[k]}</td></tr>" end puts "</table>" puts "</body></html>" copy code, store ruby file called test_cgi.rb, set executable bit on file. move file cgi-bin directory of web server on machine. use browser access file (http://localhost:8080/cgi-bin/test_cgi.rb or similar), , watch output in table change enter different values in form , submit them.
once understand round-trip server browser server you'll in place learn how sinatra builds on rack supply more features, more easily, doing cgi.
