‣ CSS-Editor - Support for custom controls

Tooling News 1.0 - 1.2



‣ Java-Editor - Wizard to generate JavaFX Getter/setters




‣ FXML-Editor - Generating controller stub




Reuseable Tooling



Components for reuse



Components for reuse‣ l10n-DSL: if you Java8, e4 and want dynamic language flipping




‣ RRobot-DSL: allows you to describe eclipse-project setups





‣ LivePreview: Reuse the live preview to present your textual content in a visual way





‣ LivePreview: Reuse the live preview to present your textual content in a visual way

‣ CSSExt-DSL: allows you to define your custom CSS-Properties



l10n



l10n-DSL



‣ DSL to define translations

l10n-DSL




‣ Uses Xtext

l10n-DSL




‣ Uses Xtext

‣ Generates code and text files

l10n-DSL




‣ Uses Xtext

‣ Generates code and text files

‣ Requires Java8

‣ Makes use of Java8 functional interfaces and method references

l10n-DSL



l10n-DSL‣ DSL to store language definitions

package sample.l10n.app.themes {bundle BasicMessages default en {

HelloWorld {en : '''Hello World''',de : '''Hallo Welt'''

}}bundle SamplePartMessages default en {

Button_title [ BasicMessages.HelloWorld ]Current_Date(DATE now) {

en : '''«now "MM/dd/yyyy"»''',de : '''«now "dd.MM.yyyy"»'''

}}

}



l10n-DSL‣ Generated artifacts

‣ ${bundle}.java: e4 message class

‣ ${bundle}.properties: Default transalations

‣ ${bundle}_${lang}.properties: Translations for the lang

‣ ${bundle}Registry.java: Registry to use for binding



‣ Use in code (Sample JavaFX)

l10n-DSL

package sample.l10n.app.themes;

public class SamplePart {@InjectSamplePartMessagesRegistry messagesReg;

@PostConstructvoid init(BorderPane pane) {

Button b = new Button();messagesReg.register(b::setText, messagesReg::Button_title);pane.setCenter(b);

Label l = new Label();messagesReg.register(b::setText,

messagesReg.Current_Date_supplier(new Date()));pane.setTop(l);

}}



‣ Use in code (Sample SWT)

l10n-DSL

package sample.l10n.app.themes;

public class SamplePart {@InjectSamplePartMessagesRegistry messagesReg;

@PostConstructvoid init(Composite pane) {

Button b = new Button(pane,SWT.PUSH);messagesReg.register(b::setText, messagesReg::Button_title);

Label l = new Label(pane,SWT.NONE);messagesReg.register(b::setText,

messagesReg.Current_Date_supplier(new Date()));}

}



Demo (Elementary)



RRobot-DSL



RRobot-DSL‣ DSL to describe Eclipse project setups




‣ Uses Xtext




‣ Uses Xtext

‣ Allows to setup

‣ JDT Projects

‣ PDE-Projects Bundles & Features



RRobot-DSLRobotTask {

// Variables to be used later onvariables = {

## Name of the bundleSTRING "BundleName" default "econsample"

}projects = {

BundleProject "${BundleName}" {manifest = ManifestFile "${BundleName}" "1.0.0" "JavaSE-1.8" {

bundlename = "${BundleName}"vendor = "BestSolution.at"

}build = BuildProperties {

}resources = {

Folder "src"}rootfragments = {

fragment "default-src" "src"}

}}

}



Demo (Run Task)



LivePreview



LivePreview‣ LivePreview was developed for FXML/FXGraph immediate feedback




‣ Expects FXML passed




‣ Expects FXML passed

‣ LivePreview requests FXML from editors who adapt to IFXMLProviderAdapter



Demo (Elemenatry & Lego-DSL & FXML-

Viewer)



LivePreviewpublic class FXMLProviderAdapter implements IFXMLProviderAdapter {

private XtextEditor editor;

public FXMLProviderAdapter(XtextEditor editor) {this.editor = editor;

}

@Overridepublic IEditorPart getEditorPart() {

return editor;}

@Overridepublic String getPreviewFXML() {

return editor.getDocument().readOnly(new IUnitOfWork<String, XtextResource>() {

@Overridepublic String exec(XtextResource resource) throws Exception {

Injector injector = LegoActivator.getInstance().getInjector("at.bestsolution.lego.Lego");PreviewGenerator generator = injector.getInstance(PreviewGenerator.class);return generator.generatePreview((Model) resource.getContents().get(0)).toString();

}

});}



CSSExt-DSL



CSSExt-DSL‣ CSS-Editor has NO hard coded properties




‣ Properties available are defined in an extra file ending with .cssext




‣ Properties available are defined in an extra file ending with .cssext

‣ CSS-Editor looks up .cssext-Files from projects classpath



package svg {prop_alignment-baseline = [ auto | baseline | before-edge | text-before-edge | middle | central | after-edge | text-after-edge | ideographic | alphabetic | hanging | mathematical | inherit ];

/** * */tspan {

/** * Documentation */alignment-baseline <prop_alignment-baseline> default: auto;

}}

‣ Used internally by e(fx)clipse runtime

‣ Implementation provided as an OSGi-Service/ServiceLoader



@Log & Logger-API‣ Simple slf4j like API

‣ Used internally by e(fx)clipse runtime

‣ Implementation provided as an OSGi-Service/ServiceLoader

‣ Multiple ways to consume

‣ Through OSGi-Service-Registry

‣ Through a factory

‣ Through DI with @Log

@ContextValue‣ Allows you to abstract away IEclipseContext#modify




public class ValuePublisherComponent {

@Injectprivate IEclipseContext context;

public void publishContext() {ListView<String> values = new ListView<>();values.getSelectionModel().selectedItemProperty().addListener( (o,newVal,oldVal) -> value.modify("contextValue",newVal));

public class ValuePublisherComponent {@Inject@ContextValue("contextValue")private Property<String> value;

public void publishContext() {ListView<String> values = new ListView<>();fxProperty.bind(values.getSelectionModel().selectedItemProperty());

@Service



@Service‣ Eclipse DI by default does NOT conform to OSGi-Service semantics

‣ Services can come and go

‣ Requestor of services is important if a ServiceFactory is used

}

@Injectpublic void setServices(@Service LoggerFactory serviceList) {

Compensator



Compensator‣ Mission 0: Must look slick!




‣ Mission 1: Create a simple source editor like Notepad++ who:

‣ Is process light-weight

‣ Makes it easy to add new language highlightings




‣ Mission 1: Create a simple source editor like Notepad++ who:

‣ Is process light-weight

‣ Makes it easy to add new language highlightings

‣ Mission 2: Allow the simple source editor to expand to a (simple) IDE:

‣ where Source-Editor, VCS (git), Ticketsystem (eg. github), CI (eg. travis) are core components fully integrated with each other

‣ Easy to integrate: Does not depend on core.resources

Compensator



Compensator - Roadmap‣ Tighter integration with git workflow

‣ Improve Java autocomplete & Error Annotations

‣ Support for JavaScript auto-complete & error reporting

‣ Support for Xtext-Languages (their upcoming IntelliJ support should help us)

‣ Connect it to Flux to get a Flux Compensator
