| <h1>First Example</h1> | |
| <p> | |
| The purpose of this first example is to make use of the classical EMF Library Model example and | |
| create a view for editing such models using an EMF Parsley enabled plug-in. | |
| </p> | |
| <p> | |
| So let's start by creating the model plug-in with | |
| </p> | |
| <p> | |
| <ol> | |
| <li>File -> New... -> Example...</li> | |
| <li>from Category "Eclipse Modeling Framework", select "Extended Library Model Example"</li> | |
| <li>press Next and Finish</li> | |
| </ol> | |
| </p> | |
| <p> | |
| You will end up with three plug-ins: | |
| </p> | |
| <p> | |
| <ul> | |
| <li>org.eclipse.emf.examples.library (the model plug-in)</li> | |
| <li>org.eclipse.emf.examples.library.edit (the edit plug-in)</li> | |
| <li>org.eclipse.emf.examples.library.editor (the editor plug-in)</li> | |
| </ul> | |
| </p> | |
| <p> | |
| Please consider that here we are starting from this well known EMF model taken out-of-the-box from Eclipse, | |
| but you can start from your EMF model (in that case you may probably omit the ".edit" and ".editor" plugins, depending on your model). | |
| </p> | |
| <p> | |
| Now you can create your first example with the appropriate wizard. | |
| </p> | |
| <p> | |
| <ol> | |
| <li>select "File" -> "New" -> "Project..."</li> | |
| <li>from the "Emf Parsley" category select "Emf Parsley Dsl based Project"</li> | |
| <li>click "Next"</li> | |
| <li>give a name to the project (e.g. "org.eclipse.emf.parsley.examples.firstexample")</li> | |
| <li>click "Finish"</li> | |
| </ol> | |
| The generated project has some classes and a <em>module.parlsey</em> file, which opens automatically. | |
| Just type the following content into the {} block (note that context assist is available) | |
| </p> | |
| <p> | |
| <div class="literallayout"> | |
| <div class="incode"> | |
| <p class="code"> | |
| <span class="keyword">parts</span> {<br/> | |
| <span class="keyword">viewpart</span> org.eclipse.emf.parsley.examples.firstexample.view.library.treeform {<br/> | |
| <span class="keyword">viewname</span> <span class="string">"My Library Tree Form"</span><br/> | |
| <span class="keyword">viewclass</span> <br/> | |
| }<br/> | |
| } | |
| </p> | |
| </div> | |
| </div> | |
| </p> | |
| <p> | |
| Here above we have just declared a view part with | |
| <ol> | |
| <li>id <em>"org.eclipse.emf.parsley.examples.firstexample.view.library.treeform"</em></li> | |
| <li>name <em>"Library Tree Form"</em></li> | |
| <li>class: not yet set, we are going to create | |
| <em>"org.eclipse.emf.parsley.examples.firstexample.views.LibraryTreeFormView"</em></li> | |
| </ol> | |
| </p> | |
| <p> | |
| So there is still an error, in fact we need to create the declared class. | |
| <em>Suggestion:</em> Just copy the above qualified class name (<em>"org.eclipse.emf.parsley.examples.firstexample.views.LibraryTreeFormView"</em>), | |
| select the project, right-click and select File -> New -> Class. Now paste the clipboard content into <em>"Name:"</em> field: the | |
| package and class name will be automatically splitted into right fields. Then click <em>"Finish"</em>. | |
| </p> | |
| <p> | |
| Now modify the view class code with this content: | |
| </p> | |
| <p> | |
| <div class="literallayout"> | |
| <div class="incode"> | |
| <p class="code"> | |
| <span class="keyword">import</span> org.eclipse.emf.parsley.views.AbstractSaveableTreeFormView;<br/> | |
| <span class="keyword">import</span> org.eclipse.emf.common.util.URI;<br/> | |
| <br/> | |
| <span class="keyword">public</span> <span class="keyword">class</span> LibraryTreeFormView <span class="keyword">extends</span> AbstractSaveableTreeFormView {<br/> | |
| <br/> | |
| <span class="keyword">protected</span> URI createResourceURI() {<br/> | |
| <span class="keyword">return</span> URI.createFileURI( System.getProperty(<span class="string">"user.home"</span>) + <span class="string">"/MyLibrary.library"</span> );<br/> | |
| }<br/> | |
| <br/> | |
| } | |
| </p> | |
| </div> | |
| </div> | |
| </p> | |
| <p> | |
| Now get back to <em>module.parlsey</em> file, go just after <em>"viewclass"</em> keyword, type <em>"LibraryTreeFormView"</em> | |
| and <em>Ctrl-Space</em>: the content assist will set automatically the correct qualified name | |
| </p> | |
| <p> | |
| <div class="literallayout"> | |
| <div class="incode"> | |
| <p class="code"> | |
| <span class="keyword">viewclass</span> org.eclipse.emf.parsley.examples.firstexample.views.LibraryTreeFormView | |
| </p> | |
| </div> | |
| </div> | |
| </p> | |
| <p> | |
| when you save the above file you will notice that a new file (<em>"plugin.xml_emfparsley_gen"</em>) | |
| is generated into the root folder of your project. Just copy this file into <em>"plugin.xml"</em>. | |
| </p> | |
| <p> | |
| Let's focus briefly on the above <em>createResourceURI()</em> method: our goal is allowing to manage | |
| a library model instance which persists on a EMF Resource. | |
| In this example we choose to use the EMF default persistence (XMI), but you can provide any URI | |
| (e.g. using Teneo, CDO or any other EMF Resource Persistence implementation) | |
| In particular here we choose to persist the Resource in a XMI file named <em>"MyLibrary.library"</em> into the user home | |
| folder (you might want to change it with any other path). | |
| </p> | |
| <p> | |
| We need a <em>Dependency</em> from the model plug-in: so open <em>MANIFEST.MF</em> file, go to <em>Dependencies</em> | |
| tab, press <em>"Add..."</em> button in <em>"Required Plug-ins"</em> section and insert <em>"org.eclipse.emf.examples.library"</em> | |
| among dependencies. | |
| </p> | |
| <p> | |
| Before executing this code we need to do some little more work in order to initialize the Resource. | |
| </p> | |
| <p> | |
| An easy way to overcome this issue can be the following: | |
| </p> | |
| <p> | |
| <ol> | |
| <li>open the class *GuiceModule (FirstexampleGuiceModule in this example) that the wizard created for you. | |
| Note that this is a key class for all customizations; it allows to override several methods in order to provide custom behaviors | |
| and implementations.</li> | |
| <li>override method <em>bindEmptyResourceInitializer()</em> providing a class for Resource initialization | |
| <div class="literallayout"> | |
| <div class="incode"> | |
| <p class="code"> | |
| <span class="keyword">public</span> Class<? <span class="keyword">extends</span> EmptyResourceInitializer> bindEmptyResourceInitializer() {<br/> | |
| <span class="keyword">return</span> LibraryEmptyResourceInitializer.<span class="keyword">class</span>;<br/> | |
| } | |
| </p> | |
| </div> | |
| </div> | |
| </li> | |
| <li>create a new class <em>LibraryEmptyResourceInitializer</em> extending from <em>EmptyResourceInitializer</em> for Resource initialization | |
| <div class="literallayout"> | |
| <div class="incode"> | |
| <p class="code"> | |
| <span class="keyword">import</span> org.eclipse.emf.parsley.resource.EmptyResourceInitializer;<br/> | |
| <span class="keyword">import</span> org.eclipse.emf.ecore.resource.Resource;<br/> | |
| <span class="keyword">import</span> org.eclipse.emf.examples.extlibrary.EXTLibraryFactory;<br/> | |
| <span class="keyword">import</span> org.eclipse.emf.examples.extlibrary.Library;<br/> | |
| <br/> | |
| <span class="keyword">public</span> <span class="keyword">class</span> LibraryEmptyResourceInitializer <span class="keyword">extends</span> EmptyResourceInitializer { <br/> | |
| <br/> | |
| <span class="keyword">public</span> <span class="keyword">void</span> initialize(Resource resource) { <br/> | |
| <span class="keyword">super</span>.initialize(resource); <br/> | |
| Library library = EXTLibraryFactory.eINSTANCE.createLibrary(); <br/> | |
| resource.getContents().add(library); <br/> | |
| } <br/> | |
| <br/> | |
| } | |
| </p> | |
| </div> | |
| </div> | |
| The method <em>initialize()</em> will be executed only when the Resource is empty | |
| (i.e., it has no contents). | |
| </li> | |
| </ol> | |
| </p> | |
| <p> | |
| now get back to the <em>MANIFEST.MF</em> and run the example | |
| </p> | |
| <p> | |
| <div class="image" > | |
| <a class="gallery" rel="prettyPhoto[all]" title="" href="images/first-example-launch.png"> | |
| <img src="images/first-example-launch.png" | |
| width="600px" | |
| /> | |
| </a> | |
| <div class="caption"> | |
| </div> | |
| </div> | |
| </p> | |
| <p> | |
| As an Eclipse RCP developer you know, of course, that this will start another Eclipse instance (unless | |
| you add an Application plug-in to the launch or define an Application in the current plug-in). | |
| </p> | |
| <p> | |
| In this second Eclipse instance you can show the View in this way: | |
| <ol> | |
| <li><em>Window -> Show View -> Other...</em></li> | |
| <li>from Category "Other", select "My Library Tree Form"</li> | |
| <li>press <em>OK</em></li> | |
| </ol> | |
| </p> | |
| <p> | |
| <div class="image" > | |
| <a class="gallery" rel="prettyPhoto[all]" title="" href="images/first-example-run.png"> | |
| <img src="images/first-example-run.png" | |
| width="600px" | |
| /> | |
| </a> | |
| <div class="caption"> | |
| </div> | |
| </div> | |
| </p> | |
| <p> | |
| With this simple view you can start editing the model instance. For example you can set the <em>"name"</em> | |
| field; as soon as you start typing characters into this field you will notice that: | |
| <ol> | |
| <li>the View turns to a <em>"dirty"</em> state (an asterisk symbol appears on the view tab)</li> | |
| <li>the <em>"Save"</em> toolbar button is enabled</li> | |
| <li>the typed characters are reflected into the label correspondent to the Library icon</li> | |
| </ol> | |
| </p> | |
| <p> | |
| if you now perform a <em>"Save"</em> action the persistence mechanism will trigger and you will see that file | |
| <span class="inlinecode"><user.home>/MyLibrary.library</span> | |
| is being created on the file system. From now on, this file will keep the state of the model object whenever | |
| you change and save it. | |
| </p> | |
| <p> | |
| To create a Writer into the Library just right-click on the Library object and select <em>New Child -> Writer</em> | |
| </p> | |
| <p> | |
| <div class="image" > | |
| <a class="gallery" rel="prettyPhoto[all]" title="" href="images/createWriter.png"> | |
| <img src="images/createWriter.png" | |
| width="600px" | |
| /> | |
| </a> | |
| <div class="caption"> | |
| </div> | |
| </div> | |
| </p> | |
| <p> | |
| Please note that you might see a slightly different content in the above context-menu in case you deleted | |
| the .edit plugin when creating the model (e.g. <em>"Writers Writer"</em> instead of <em>"Writer"</em>, <em>"Stock Book"</em> instead of <em>"Book"</em> and | |
| similar (this is because with EMF it is possible to customize labels also via .edit plugin). | |
| </p> | |
| <p> | |
| Now set for instance the writer <em>"name"</em> field and save. | |
| Now just play around creating Books, associating them to Writers and so on. | |
| As you can see you can entirely manage the EMF model instance: creating, modifying and deleting elements. | |
| </p> | |
| <p> | |
| Whenever the current selection on the upper side of the view changes, then the lower side shows the detail | |
| of this selection. | |
| </p> | |
| <p> | |
| However, up to this point, you have no control over the field to be shown and its order; for example | |
| you may want just the <em>"name"</em> attribute for the Library and <em>"name", "address" and "books"</em> attributes | |
| for Writers and maybe <em>"title", "authors" and "category"</em> for Books. | |
| </p> | |
| <p> | |
| Well, it's indeed very easy to obtain this: just edit the <em>module.parsley</em> file, | |
| adding the following import (without ending line with ";") | |
| </p> | |
| <p> | |
| <div class="literallayout"> | |
| <div class="incode"> | |
| <p class="code"> | |
| <span class="keyword">import</span> org.eclipse.emf.examples.extlibrary.* | |
| </p> | |
| </div> | |
| </div> | |
| </p> | |
| <p> | |
| and then defining the features to show | |
| </p> | |
| <p> | |
| <div class="literallayout"> | |
| <div class="incode"> | |
| <p class="code"> | |
| <span class="keyword">module</span> ... {<br/> | |
| <br/> | |
| <span class="keyword">parts</span> { <br/> | |
| ... <br/> | |
| }<br/> | |
| <br/> | |
| <span class="keyword">featuresProvider</span> {<br/> | |
| <span class="keyword">features</span> {<br/> | |
| Library -> name<br/> | |
| Writer -> name, address, books<br/> | |
| Book -> author, title, category<br/> | |
| }<br/> | |
| }<br/> | |
| } | |
| </p> | |
| </div> | |
| </div> | |
| </p> | |
| <p> | |
| Remeber that code completion is available, just exploit it since it helps a lot. | |
| </p> | |
| <p> | |
| If you restart now the application you will see that, when selecting an object, only the declared attributes | |
| will be shown. Furthermore, they are shown in the specified order. | |
| </p> | |
| <p> | |
| Did you run the application in Debug mode? Well, then you can change fields and order, save and see the | |
| changes without even restarting the application. | |
| </p> | |
| <p> | |
| Do you want to change text used for attribute labels in the detail? Just add the following: | |
| </p> | |
| <p> | |
| <div class="literallayout"> | |
| <div class="incode"> | |
| <p class="code"> | |
| <span class="keyword">propertyDescriptionProvider</span> {<br/> | |
| <span class="keyword">text</span> {<br/> | |
| Book : author -> <span class="string">'Wrote by:'</span><br/> | |
| Writer : name -> <span class="string">'Name:'</span><br/> | |
| }<br/> | |
| } | |
| </p> | |
| </div> | |
| </div> | |
| Or do you want to change the label shown on the tree nodes on the upper side and as detail title? | |
| Maybe want to format the book label like this? | |
| <div class="literallayout"> | |
| <div class="incode"> | |
| <p class="code"> | |
| <span class="keyword">labelProvider</span> {<br/> | |
| <span class="keyword">text</span> {<br/> | |
| Book b -> <span class="string">'"'</span> + b.title + <span class="string">'"'</span> +<span class="string">' (by '</span>+ b.author.name + <span class="string">')'</span><br/> | |
| }<br/> | |
| } | |
| </p> | |
| </div> | |
