The following code was used to upload an image file to the web server. Source code origin: Ruby Language Stuff | mod_ruby File upload scripts [zytrax.com]

file: file_upload.cgi

#!/usr/bin/ruby

# ruby script fragment
require 'cgi'
require 'stringio'

cgi = CGI.new() # New CGI object
puts "Content-Type: text/plain"
puts
print ''

# get uri of tx'd file (in tmp normally)
tmpfile = cgi.params['myfile'].first.path

This example will show you how to escape and un-escape a value to be included in a URI and within HTML.

require 'cgi'

# escape
name = "ruby?"
value = "yes"
url = "http://example.com/?" + CGI.escape(name) + '=' + CGI.escape(value) + "&var=T"
# url: http://example.com/?ruby%3F=yes&var=T
html = %(example)
# html: example

# unescape
name_encoded = html.match(/http:([^"]+)/)[0]

The eval method in Ruby executes ruby code from a string.

eval("puts 'Hello World'")

output:

Hello World

I’m currently testing disk catalog software programs as you might have guessed already. Cathy is the second that I’m going to write a review about, the first disk catalog software was Visual CD. Cathy uses a different approach than Visual CD; It’s a portable and an ultra-fast disk catalog software which does not have all the features of Visual CD.

There are tons of applications and other instances where you need to either test using dates, or you actually need random dates. If you want to write posts on your blog ahead of time, and post them randomly between the 1st of March and the 2nd of April, the random date and time value generator is the tool for you.

Versioning is a pretty useful concept. It basically means backing up documents and files before changes are made to it so that the user can revert back to a previous version with ease. Versioning is not limited to text documents, it can also be used for images or coding applications.

Windows is only displaying the current time in hours and minutes in the system tray and detailed information can only be accessed with a double-click on the clock. A double-click opens a detailed view that is showing the seconds and the date as well. If you want to display those information in the system tray you have to use third party software like TClock Light which adds the functionality to Windows (except Windows Vista).

This code uses the Ruby gem 'syntax' to create an XML file containing the HTML tags around the code, which is then transformed into an HTML file. The working example was first built using coding examples from Howto format ruby code for blogs [wolfman.com] and Formatting Ruby and HTML code for blog posting [blogspot.com]
