Tkx::Tutorial Perl module contains a tutorial about how to use Tkx.

Tk is a toolkit that allows you to create applications with graphical interfaces for Windows, Mac OS X and X11. The Tk toolkit is native to the Tcl programming language, but its ease of use and cross-platform availability has made it the GUI toolkit of choice for many other dynamic languages as well.

Tkx is a Perl module that makes the Tk toolkit available to Perl programs. By loading the Tkx module Perl programs can create windows and fill them with text, images, buttons and other controls that make up the user interface of the application.

Hello World

Lets start with the mandatory exercise of creating an application that greats the world. Here we make the application window contain a single button which will shut down the application if clicked. The code to make this happen is:

use Tkx;

Tkx::button(".b",
-text => "Hello, world",
-command => sub { Tkx::destroy("."); },
);
Tkx::pack(".b");

Tkx::MainLoop()

Save this to a file called hello.pl and then run perl hello.pl to start up the application. A window with the text "Hello, world" should appear on your screen.
After the Tkx module has been loaded by the use Tkx statement the application will show an empty window called ".". We create a button with the name ".b" and tell the window to display the button with the call to Tkx::pack(). After the layout of the window has been set up we need to pass control back to Tk so that it can draw the window and invoke our callback if the button is clicked. This is achieved by the Tkx::MainLoop() call at the end. Clicking the button will invoke the subroutine registered with the -command option of the button. In this case the callback simply destroys the window, which in turn will terminate the application.

On Deploying Perl Applications

% sshnuke.pl 10.2.2.2 -rootpw="Z1ON0101"
Perl v5.6.1 required--this is only v5.6.0, stopped at sshnuke.pl line 1.
BEGIN failed--compilation aborted at sshnuke.pl line 1.

Q: "Help! I cant run your program!"
A1: Install Perl & perl -MCPAN -einstall(...)
How do we know which modules are needed?
New versions of CPAN modules may break sshnuke.pl
A2: Install Perl & tar zxf my_perllib.tgz
Possibly overwriting existing modules; not cross-platform at all
A3: Use the executable generated by perlcc sshnuke.pl
Impossible to debug; perlcc usually does not work anyway

Prima::tutorial is an introductory tutorial.

Programming graphic interfaces is often considered somewhat boring, and not without a cause. It is a small pride in knowing that your buttons and scrollbars work exactly as millions of others buttons and scrollbars do, so whichever GUI toolkit is chosen, it is usually regarded as a tool of small importance, and the less obtrusive, the better.

Given that, and trying to live up to the famous Perl making easy things easy and hard things possible mantra, this manual page is an introductory tutorial meant to show how to write easy things easy. The hard things are explained in the other Prima manual pages ( see Prima ).

IPTables-tutorials aim is to explain iptables in a complete and simple way. The iptables-tutorial is currently rather stable, and contains information on all the currently available matches and targets (in kernel), as well as a couple of complete example scripts and explanations. It contains a complete section on iptables syntax, as well as other interesting commands such as iptables-save and iptables-restore.

The tutorial has recently been under heavy scrutiny and updating, as can be seen in this, the latest version of the tutorial. It is now also available in bookform from Lulu.com. If you feel like contributing or donating to the author of this tutorial, please do buy the book! Thank you!

If you need help, you are better off by asking the netfilter mailing list which you can reach at netfilter at lists.netfilter.org. For more information on this, visit the netfilter mailinglist page. You may also contact the linuxsecurity mailing list at security-discuss AT linuxsecurity dotcom. Both are fairly large, and should be able to help you much much better than I can.

Template::Tutorial::Web is a Perl module for generating web content using the template toolkit.

This tutorial document provides a introduction to the Template Toolkit and demonstrates some of the typical ways it may be used for generating web content. It covers the generation of static pages from templates using the tpage and ttree scripts and then goes on to show dynamic content generation using CGI scripts and Apache/mod_perl handlers.

Various features of the Template Toolkit are introduced and described briefly and explained by use of example. For further information, see Template, Template::Manual and the various sections within it. e.g.

perldoc Template # Template.pm module usage
perldoc Template::Manual # index to manual
perldoc Template::Manual::Config # e.g. configuration options

The documentation is now also distributed in HTML format (or rather, in the form of HTML templates). See the docs sub-directory of the distribution for further information on building the HTML documentation.

If youre already reading this as part of the HTML documentation, then you dont need to worry about all that. You can have a seat, sit back. back and enjoy the rest of the tutorial...

Test::Unit::Tutorial is a Perl module that contains a tutorial on unit testing.

SYNOPSIS

perldoc Test::Unit::Tutorial

Here should be extensive documentation on what unit testing is, why it is useful, and how to do it with the Test::Unit collection of modules.

Sorry for not implementing this yet.

Please have a look at the examples in the examples directory and read the README file that came with this distribution.

A short tutorial on how to use the unit testing framework is included in Test::Unit::TestCase.

Further examples can be found by looking at the self test collection, starting in Test::Unit::tests::AllTests.

Chatbot::Alpha::Tutorial is a beginners guide to Chatbot::Alpha 2.x.

INTRODUCTION

What is Chatbot::Alpha?

Chatbot::Alpha is a Perl module for reading and processing Alpha code. Alpha code is a command-driven response language, primarily used for chatterbots.

The language format is quite simple: its a line-by-line language. The first character is the command, followed by the commands data. The simplest of all Alpha replies is the standard one-way question and answer:

+ hello bot
- Hello human.

Alpha Commands Overview

Here are all the commands supported by Chatbot::Alpha:
+ (Plus)

The + symbol is the basis of all your replies. Its the trigger--that is, what the user says to activate that reply. In most cases this command comes first in a reply, followed by supporting commands that tell the bot what to do next.

- (Minus)

The - command has many purposes. In the example above, a single +TRIGGER and a single -REPLY will give you a one-way question-answer case. If you use multiple -REPLYs under one +TRIGGER, then they will become random responses. On *CONDITIONS, the -REPLYs will be called when no condition returns true. On &HOLDERS, the -REPLY is the first thing the bot sends. And the list goes on... well get into the many uses for -REPLY later.

% (Percent)

The % command is for "that" emulation. If youve worked with AIML youll know what that refers to. Its there to help take the A.D.D. syndrome out of your bots. You can make specific replies based on what the bot last said. Like if the bot asks "Do you have any pets?" and the user says "yes", the bot can ask "What kind of pets?" instead of a generic reply to "yes". Youll learn all about this in the tutorial later.

^ (Carat)

The ^ command is to continue from your last -REPLY. For example, if your reply is very long and you want to break it down a few lines in the reply file (as not to have a horizontal scrollbar and be hard to read), this is the command to use. The ^CONTINUE command will adds its data to the last -REPLY you used under the +TRIGGER.

@ (At)

The @ command is for a redirection. Alpha triggers are "dead-on", meaning "hello|hey" is literally "hello|hey", not "hello OR hey". So when you want one to point to the other, use the @REDIRECT command.

* (Star)

The * is for conditionals. Youll learn about these later as well.

& (Amperstand)

This is for simple conversation holders. Emphasis is on the word "simple." They dont always work, so youd use %THAT if it was really important. The &HOLDER command is slowly becoming deprecated.

# (Pound)

The # command is for executing Perl codes within your reply set. Sometimes Alpha just cant handle the complex tasks you have in mind, and this can fill in all the blanks (assuming youre fluent with Perl anyway).

/ (Slash)

This is comment data, not processed within Chatbot::Alpha.
LessThan and GreaterThan

The > and < are labels. Right now theyre used only for topics.

PDF::Reuse::Tutorial is a Perl module that will teach you how to produce PDF-files with PDF::Reuse.

In this tutorial I will show some aspects of PDF::Reuse, so you should be able to use it in your own programs. Most important is how to produce and reuse PDF-code, and then if you are interested, you can look at Graphics and JavaScript, so you can to do special things.

Reusing code:

You can take advantage of what has been done before, it is not necessary to start from scratch every time you create a PDF-file. You use old PDF-files as a source for forms, images, fonts and texts. The components are taken as they are, or rearranged, and you add your own texts and you produce new output.
If you dont care too much about the size of your templates, you should make them with a commercial, visual tool, thats most practical; and then you should use PDF::Reuse to mass produce your files. In this tutorial I show in many places how create single files with PDF::Reuse. That is possible, but more of an exception. I do it here to show the technique. You will anyway need it to add texts and graphics to your templates.

Graphics:

With this module you get a good possibility to program directly with the basic graphic operators of PDF. This is perhaps an advanced level, and you can avoid it if you want. On the other hand, it is not very difficult, and if you take advantage of it, your possibilities to manage text and graphics increase very much. You should look at the "PDF-reference manual" which probably is possible to download from http://partners.adobe.com/asn/developer/acrosdk/docs.html. Look especially at chapter 4 and 5, Graphics and Text, and the Operator summary.
Whenever the function prAdd() is used in this tutorial, you can probably get more explanations in the "PDF-reference manual". The code, you add to the content stream with prAdd(), has to follow the PDF syntax completely.

JavaScript:

You can add JavaScript to your PDF-file programmatically. This works with Acrobat Reader 5.0.5 or Acrobat 5.0 and higher versions.

You should have the "Acrobat JavaScript Object Specification" by hand. If you havent got Acrobat, you can probably download it from http://partners.adobe.com/asn/developer/technotes/acrobatpdf.html. It is technical note # 5186. JavaScript for HTML and PDF differs so much that you need the manual, even if you know JavaScript very well.
