ZEND_TOOL IN ZF 1.8 By Ralph Schindler

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

What’s this thing all about?

| Jul-1-09 Overview | 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

| Jul-1-09 Overview | 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

| Jul-1-09 Overview | 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/)

| Jul-1-09 Overview | 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

“ ADVANCED USAGE

So, how do I extend this thing?

| Jul-1-09 Advanced Usage | 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

| Jul-1-09 Advanced Usage | 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.

| Jul-1-09 Advanced Usage | 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

| Jul-1-09 Advanced Usage | 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

| Jul-1-09 Advanced Usage | 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

“ WRAPPING IT UP

What’s next? Wha’ts on the horizon?

| Jul-1-09 Advanced Usage | 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

| Jul-1-09 Name of this section | 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
