3. OVERVIEW
“
What’s this thing all
about?
Overview | Jul-1-09 | 3

4. Overview
• The Problem – all the buzzwords
 RAD – Rapid Application Development
 Code Generation
• The generation of code during “development time” that will run
during “production time”
• Development time code generation is ALWAYS better than
runtime introspection
 Scaffolding
• Templates
• Meta programming
• CRUD
Overview | Jul-1-09 | 4

5. Overview
• In a nutshell:
 “Zend_Tool is both RAD tools as well as a framework for
exposing your own set of tooling needs to the Zend_Tool user
interface.”
• Main Classes & APIs:
 Zend_Tool_Framework
 Zend_Tool_Project
• Supporting Classes & APIs:
 Zend_CodeGenerator
 Zend_Reflection
Overview | Jul-1-09 | 5

6. Overview
• Download and go
• SVN
 Create a link to the proper runner (zf.sh/zf.bat)
• Preferably in the system path
 Add Zend Framework library to global include_path
• Zend Server
• Pear Channel (http://pear.zfcampus.org/)
Overview | Jul-1-09 | 6

7. Overview
• How it works
 Zend_Tool_Framework looks for providers, by default, on the
include_path
 Zend_Tool_Project is consumed by Zend_Tool_Framework
• This allows Zend_Tool_Project to be only concerned with
“project” problems
• This also allows Zend_Tool_Framework to focus on the problem
of knowing which requests are good, and knowing how to
dispatch said request
 Zend_Tool_Framework provides a client to the user
 That client in 1.8 is the command line client

19. ADVANCED USAGE
“
So, how do I extend this
thing?
Advanced Usage | Jul-1-09 | 19

20. Advanced Usage
• Zend_Tool_Framework Architecture
 Registry
• A container for all of the Zend_Tool_Framework sub componets
 Providers
• The built in providers
 Loaders
• The component responsible for finding providers & manifests
 Manifest
• A dictionary of metadata to be used by clients and providers
 Client
• The subcomponent responsible for presenting the toolchain to
the user as well as building and dispatching requests
Advanced Usage | Jul-1-09 | 20

21. Advanced Usage
• Zend_Tool_Project Architecture
 Project Profile
• The description of the project in terms as a tree structure of
resources
 Resource
• A resources is a node in the “project profile tree”
• Can be a single node, or a parent of a collection of nodes
• Is further described by the “context” associated with it.
 Providers
• Set of providers responsible for project based capabilities
 Context
• An object that describes the role of any given resources.
Advanced Usage | Jul-1-09 | 21

22. Advanced Usage
• Zend_Reflection
 Extends the API of PHP’s Reflection class to handle some
missing functionality
• Docblock introspection (ability to get tags and descriptions)
• File introspection
Advanced Usage | Jul-1-09 | 22

23. Advanced Usage
• Zend_CodeGenerator
 Purpose is to generate OO code with an OO interface
 API very similar to Reflection API, but the purpose is exactly
the opposite
 generate() method produces Zend/PEAR standard compliant
object oriented code
 Target use case: Assisting RAD and facilitating iterative
development
Advanced Usage | Jul-1-09 | 23

24. Advanced Usage
• Iterative Development
 Use Zend_Tool to generate file & class
 Modify file with external tool
• Example: use studio to fill in the body of an Action Controllers
action
 Use Zend_Tool to modify file & class
• Example: adding an action to an already generated and modifed
Action Controller
Advanced Usage | Jul-1-09 | 24

25. Advanced Usage
• Next slides are old demonstration
• API still applicable, substitute Zend for ZendL

Generation
 Start with a schema

52. WRAPPING IT UP
“
What’s next? Wha’ts on
the horizon?
Advanced Usage | Jul-1-09 | 52

53. Wrapping It Up
• Most immediately
 Code and slides published to my blog
• http://ralphschindler.com
 End of week a tutorial on DevZone
• Same code, only heavily documented to demonstrate what is
going on
• Some additional functionality inside the code
• Iterative examples
Name of this section | Jul-1-09 | 53

54. Wrapping It Up
• Whats to come in 1.9?
 A setup script
 Better include_path management
 New Providers!
• Model provider
• DbTable provides
 Custom profiles
• Whats on the TODO list?
 Importing of existing project (resource auto-detection)
 Web based client
 Zend Studio client
