WORKSPACE MODELING
• Represents php projects in a tree structure, visualized by the “php Explorer" view
• Base class is org.eclipse.dltk.core.IModelElement
• Get model by ModelManager.getModelManager().getModel()
IScriptProject
IScriptFolder
IType
IField
IField
IMethod
IPackageFragment[]
BuiltinProjectFragment
IScriptModule

CODE REPRESENTATION & MANIPULATION
• Based upon the Abstract Syntax Tree (AST)• Allows you to modify the tree and reflects
modifications in the php source code
// ... Create a Program AST instance ...
program.recordModifications();
// ... fetch the statement component ...
statements.add(ast.newEchoStatement (ast.newScalar("'Hello World!'")));
// .. More changes go here...
TextEdit edits = program.rewrite(document, null);

SHARED AST PROVIDER
• Protected and shared AST (Rewriting is restricted)
SharedASTProvider.getAST(ISourceModule, WAIT_FLAG, IPM)
Mark occurrence feature is available by analyzing the shared AST

PHP EDITOR
• Based upon wst.sse.ui.StructuredTextEditor
• Extend syntax coloring with: Setting your own source parser
internal.core.documentModel.parser.SourceParser Construct php regions
core.documentModel.parser.regions.IPhpScriptRegion
Set your coloring policy with ui.editor.highlighter.LineStyleProviderForPhp

LISTEN TO ELEMENTS CHANGE
• Register by:DLTKCore.addElementChangedListener(IElementChangedListener)
• Unregister by:DLTKCore.removeElementChangedListener(IElementChangedListener)
/** * An element changed listener receives notification of changes to script * elements maintained by the script model. * <p>*/public interface IElementChangedListener {
public void elementChanged(ElementChangedEvent event);
}
/** * An element changed listener receives notification of changes to script * elements maintained by the script model. * <p>*/public interface IElementChangedListener {
public void elementChanged(ElementChangedEvent event);
}

LAUNCH CONFIGURATION
• Based upon org.eclipse.debug
• Debug session listener should extend org.eclipse.php.debug.core.debugger.IDebugHandler
public interface IDebugHandler { public void sessionStarted(String fileName, String uri, String query, String options); public void sessionEnded(); public void connectionTimedout(); public void multipleBindOccured(); public void handleScriptEnded(); public void connectionEstablished(); public void connectionClosed(); public void newOutput(String output); public void newHeaderOutput(String output); public void parsingErrorOccured(DebugError debugError); public void wrongDebugServer(); public void ready(String fileName, int lineNumber); public void debugChanged(); public void debuggerErrorOccured(DebugError debugError); public IRemoteDebugger getRemoteDebugger(); public void setDebugTarget (PHPDebugTarget debugTarget); public PHPDebugTarget getDebugTarget();}
