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.

Task::Catalyst::Tutorial is a Perl module that installs everything you need to learn Catalyst.

SYNOPSIS

Installs the example "MyApp" described in Catalyst::Manual::Tutorial, and all its dependencies.

XML::Smart::Tutorial is a Perl module with tutorials and examples for XML::Smart.

SYNOPSIS

This document is a tutorial for XML::Smart and shows some examples of usual things.

OpenInteract2::Manual::Tutorial is a Perl module that will teach learn you how to create and modify a package.

SYNOPSIS

This tutorial will show you the different methods for creating a package and how to maintain them.

CREATING THE PACKAGE

A word on the example

For our example were going to create a book package. This will keep track of all our books and allow us to search our library, add new books, update existing ones and remove old ones. It wont be the backbone for a massive e-commerce website to make you lots of money. It does not attempt to best model the relationships for all the data about a book.

Looking for shortcuts?

If you want to get something running in the fastest manner possible we can generate a simple CRUDS application for you. (CRUDS: CReate Update Delete Search) Just run something like the following:

$ oi2_manage easy_app --package=book --table=book
--dsn=DBI:Pg:dbname=mylibrary --username=foo --password=bar

This will create a simple application built off a table book with templates and objects for searching, creating, updating and removing objects. (More at OpenInteract2::Manage::Package::CreatePackageFromTable.)
Since this is a tutorial well assume you want to read to learn, so on we go.

Generating the skeleton

OpenInteract comes with tools to create a skeleton package -- we dont want to do all this from scratch! The skeleton package has the directory structure, metadata and a number of files to get you going on your new package. Heres how to create one -- be sure to first go to the directory under which the package will be created:

$ oi2_manage create_package --package=book

And heres what youll see:

PROGRESS: Starting task
PROGRESS: Task complete
ACTION: Create package book
OK: Package book created ok in /path/to/my/book

And now lets see what it created:

$ find book/
book/
book/conf
book/conf/spops.ini
book/conf/action.ini
book/data
book/doc
book/doc/book.pod
book/struct
book/template
book/template/sample.tmpl
book/script
book/html
book/html/images
book/OpenInteract2
book/OpenInteract2/Action
book/OpenInteract2/Action/Book.pm
book/OpenInteract2/SQLInstall
book/OpenInteract2/SQLInstall/Book.pm
book/package.ini
book/MANIFEST.SKIP
book/Changes
book/MANIFEST

These files and directories are explained in OpenInteract2::Manual::Packages.

You will normally need to edit/add the following:

book/package.ini # Add name, version, author information
book/MANIFEST # Add names of distribution files
book/conf/spops.ini # Describe the objects your package uses
book/conf/action.ini # Map URLs to handlers in your package
book/data # Specify the initial data and security
book/struct # Describe the tables used to store your objects
book/template # HTML to display and manipulate your objects
book/OpenInteract2 # Optional Perl modules defining object behavior
book/OpenInteract2/Action # Manipulate objects for desired functionality
book/OpenInteract2/SQLInstall # Tell the installer about your tables, data, security
book/doc/book.pod # Last but not least, tell the world about it

Short sidebar: Creating a MANIFEST

Notice that we create a MANIFEST file for you when the package is created. As you add more files to your package youll need to add them to your book/MANIFEST. Fortunately, it can be created automatically:

$ cd /path/to/mypackage
$ perl -MExtUtils::Manifest -e ExtUtils::Manifest::mkmanifest()

Thats it! If you have an old MANIFEST file in the directory it will be copied to MANIFEST.bak. Also note that files matching patterns in the book/MANIFEST.SKIP file will not be included.

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...

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.

Jifty::Manual::Tutorial is a Perl module for Zero to Jifty in a Jiffy.

This tutorial should give you everything you need to build your first application with Jifty.

HOW TO

The requirements
Heres what you need to have installed -- at least when we write it.

Installing Jifty
No bones about it. We believe pretty strongly in the DRY (Dont Repeat Yourself) principle. Thats one of the big reasons we love Perl and CPAN. Jifty makes use of lots of amazing code from CPAN. At last count, it directly depended on 60 packages from CPAN. Most of these libraries are cross-platform pure-Perl packages and should run great out of the box on any platform you can get Perl onto.

Weve gone to lengths to make sure you dont spend your day downloading library after library by bundling everything we can inside the Jifty package. With luck, all youll need to install is a few tricky libraries that actually need to be compiled for your operating system. (Little things like Perls database interface and the embedded SQLite that Jifty defaults to.)

You can either grab a complete Jifty package from http://download.jifty.org/pub/jifty/ or install from CPAN. If you get the slim version from CPAN, youll have to install Jiftys dependencies yourself. (Though we help out with that where we can.) If you want to get up and running quickly, grab the latest version from:

http://download.jifty.org/pub/jifty/

Either way, the installation process is the same:

# tar xzvf jifty- .tgz
# cd jifty-
# perl Makefile.PL
# make
# make test
# make install

If the tests dont pass, we want to hear about it. Please join us on jifty-devel@lists.jifty.org and report the failure. (See "GETTING HELP" below for info on how to join the list.)
