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.

Imager::Tutorial is an introduction to Imager.

Before you start

If you have the necessary knowledge, install the image format libraries you want Imager image file support for, and Imager itself, otherwise arrange to have it done.
You will also want some sort of image viewer tool, whether an image editor like Photoshop or the GIMP, or a web browser.

Hello Boxes! - A Simple Start

As with any perl program its useful to start with a #! line, and to enable strict mode:

#!/usr/bin/perl -w
# you might to use warnings; instead of the -w above
use strict;

These lines will be omitted in further examples.

As with any module, you need to load it:

use Imager;

Now create a image to draw on:

my $image = Imager->new(xsize => 100, ysize => 100);

and draw a couple of filled rectangles on it:

$image->box(xmin => 0, ymin => 0, xmax => 99, ymax => 99,
filled => 1, color => blue);
$image->box(xmin => 20, ymin => 20, xmax => 79, ymax => 79,
filled => 1, color => green);

Since the first box fills the whole image, it can be simplified to:

$image->box(filled => 1, color => blue);

and save it to a file:

$image->write(file=>tutorial1.ppm)
or die Cannot save tutorial1.ppm: , $image->errstr;

So our completed program is:

use Imager;

my $image = Imager->new(xsize => 100, ysize => 100);

$image->box(filled => 1, color => blue);
$image->box(xmin => 20, ymin => 20, xmax => 79, ymax => 79,
filled => 1, color => green);

$image->write(file=>tutorial1.ppm)
or die Cannot save tutorial1.ppm: , $image->errstr;

Template::Tutorial are template toolkit tutorials.

This section includes tutorials on using the Template Toolkit. Subjects currently include an general overview of the Template Toolkit, showing users how to get quickly up to speed building web content, and a tutorial on generating and using data files, with particular reference to XML.

Template::Tutorial::Web

Generating Web Content Using the Template Toolkit

This tutorial provides an introduction to the Template Toolkit and a "quick start" guide to getting up to speed. Its primarily focus is on using the Template Toolkit to build web content and it covers 4 basic areas: using tpage and ttree; using the Template.pm module in CGI scripts; writing Apache/mod_perl handlers; and extending the toolkit by writing plugins.

Template::Tutorial::Datafile

Creating Data Output Files Using the Template Toolkit

This tutorial gives an overview of the Template Toolkit, showing in particular how to use it to read and write data files in various different formats and styles. It was written by Dave Cross and first appeared as a lead article at http://www.perl.com/ earlier in the year (2001).

Gantry::Docs::Tutorial is a Perl module for The Gantry Tutorial.

Gantry is a mature web framework, released in late 2005 onto an unsuspecting world. For more information on the framework, its features and history, see Gantry::Docs::About.
Here we will explore the basic workings of Gantry by constructing a very simple application. Dont let the simplicity of this example fool you -- this framework has extreme flexibility in delivering applications with web and scripted components. The example in this document is only to get you started.

This document begins by describing a simple one-table management application. It walks through the process of building the application. Then, it shows a tool -- called Bigtop -- which can be used to build the application from a relatively small configuration file. Finally, it shows how to add another table and regenerate the app via Bigtop.

Album::Tutorial is a Perl module on how to use the Album program.

SYNOPSIS

This tutorial describes the basic use of the Album program to create and maintain browser based photo albums.

Getting started

To get started, create a new directory and cd to it. Create a subdirectory large and put some pictures there. If you have installed the album tool in your execution path, you can now execute it as follows:

$ album -v
No info.dat, adding images from large
info.dat: Cannot update (does not exist)
Number of entries = 7 (7 added)
mkdir thumbnails
mkdir icons
mkdir css
Creating icons: first-gr.png first.png ... sound.png movie.jpg
Creating style sheets: common.css index.css ... journal.css
im023.jpg: thumbnail OK
im024.jpg: thumbnail OK
im025.jpg: thumbnail OK
im026.jpg: thumbnail OK
im027.jpg: thumbnail OK
im028.jpg: thumbnail OK
im029.jpg: thumbnail OK
Creating pages for 7 images
(Needed to write 7 image pages)
Creating pages for 1 index
(Needed to write 1 index page)

Your results will vary, but be similar to this example run. What you can see is that album found 7 images in the large directory, created thumbnails, icons and css directories, created thumbnails by resizing the images, and finally created the HTML pages. You can inspect your first photo album by opening file index.html with your favorite browser. You can click on any image to see the larger version. Navigation buttons are provided to the left of the image.

It is interesting to run album again:

$ album -v
No info.dat, adding images from large
info.dat: Cannot update (does not exist)
Number of entries = 7 (7 added)
.......[7]
Creating pages for 7 images
(No image pages needed updating)
Creating pages for 1 index
(No index pages needed updating)

album tries to avoid doing unnecessary work as much as possible. In this case, all thumbnails and image and index pages are up to date. The line of periods shows progress, one period for each image processed.

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.

GTK Cervi project is a multiplayer Cervi clone.
Im not really sure if Cervi is original name of it but I know this game as Cervi so it will be named GTK Cervi. It is a multiplayer game (for 2-8 players) where players drive their worms.
Worms are getting longer and players mustnt collide with any worm. Winner is the last surviving worm. For more information see `Gameplay internals section.
Differences between "GTK Cervi" and the original Cervi:
- Some little differences in gameplay - these wont be fixed because I like this gameplay.
- Our cervs are antialiased.
- We have different field size, and it can be changed.
- Different controls.
- More players.
- Different scoring.
- Hatrick and extra hatrick bonuses.

GTK Photo Gallery is an album to manage small and medium-sized photograph collections. It is possible to upload images to an online laboratory.
It allows quick management by processing multiple files together. Rotate, delete, move, and manage descriptions can be done for all files in one directory at once.
GTK Photo Gallery is implemented with GTK2-Perl, and due to the lack of a Web server in between, it is much faster than CGI-based scripts. It uses the same directory structure as (and can be used together with) My Photo Gallery (a set of CGI scripts).
It is possible to export (and import) an album in 0.7, 4.7 or 8.5 GB parts for easy CD/DVD backup.
Each part contains a html index as overview and for navigation. User can choose the thumnail sizes to export.
This can be used to create a simple static web album.
Enhancements:
- Automatic configuration is done on startup if theres no configuration file.
- Speed enhancements on applying changes to albums and bugfixes were done.
