2 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 30-Jun-09 2

3 OVERVIEW What s this thing all about? Overview 30-Jun-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 30-Jun-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 30-Jun-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 ( Overview 30-Jun-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 Overview 30-Jun-09 7

8 BASIC USAGE So, how do I use this thing? Basic Usage 30-Jun-09 8

19 ADVANCED USAGE So, how do I extend this thing? Advanced Usage 30-Jun-09 19

20 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 30-Jun-09 20

21 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 30-Jun-09 21

22 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 30-Jun-09 22

23 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 30-Jun-09 23

24 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 30-Jun-09 24

25 Next slides are old demonstration API still applicable, substitute Zend for ZendL Advanced Usage 30-Jun-09 25

52 WRAPPING IT UP What s next? Wha ts on the horizon? Advanced Usage 30-Jun-09 52

53 Wrapping It Up Most immediately Code and slides published to my blog 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 30-Jun-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 Name of this section 30-Jun-09 54

55 Wrapping It Up Questions? Name of this section 30-Jun-09 55
