Zend_Tool In ZF 1.8 Webinar

Overview • Overview  The Problem  The Solution  Obtaining Zend_Tool • Basic Usage  Zend_Tool usage OTB (out the box)  Zend_CodeGenerator & Zend_Reflection • Advanced Usage  Extending Zend_Tool Overview | Jul-1-09 | 2

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

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

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

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

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 Overview | Jul-1-09 | 7

BASIC USAGE “ So, how do I use this thing? Basic Usage | Jul-1-09 | 8

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

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

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

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

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

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

Advanced Usage • Next slides are old demonstration • API still applicable, substitute Zend for ZendL Advanced Usage | Jul-1-09 | 25

Advanced Usage • Zend_CodeGenerator / Reflection example Advanced Usage | Jul-1-09 | 26

Advanced Usage • Lets explore a simple problem: Db Table & Model Generation  Start with a schema  Generate Db Table Files  Generate Model Files Advanced Usage | Jul-1-09 | 30

Advanced Usage Advanced Usage | Jul-1-09 | 31

Advanced Usage • Files needed to facilitate this endeavor • (These are in the include_path) Advanced Usage | Jul-1-09 | 32

Advanced Usage • Start with the simpler Abstract & ModelProvider Advanced Usage | Jul-1-09 | 34

Advanced Usage • The more complex DbTable provider & generator • This will include some Zend_Application integration Advanced Usage | Jul-1-09 | 42

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

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

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 Name of this section | Jul-1-09 | 54
