12 Components for reuse

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

14 Components for reuse l10n-dsl: if you Java8, e4 and want dynamic language flipping RRobot-DSL: allows you to describe eclipse-project setups

15 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

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

17 l10n

18 l10n-dsl

19 l10n-dsl DSL to define translations

20 l10n-dsl DSL to define translations Uses Xtext

21 l10n-dsl DSL to define translations Uses Xtext Generates code and text files

22 l10n-dsl DSL to define translations Uses Xtext Generates code and text files Requires Java8 Makes use of Java8 functional interfaces and method references

23 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"»'''

24 l10n-dsl Generated artifacts ${bundle.java: e4 message class ${bundle.properties: Default transalations ${bundle_${lang.properties: Translations for the lang ${bundleregistry.java: Registry to use for binding

25 l10n-dsl Use in code (Sample JavaFX) package sample.l10n.app.themes; public class SamplePart SamplePartMessagesRegistry void 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);

26 l10n-dsl Use in code (Sample SWT) package sample.l10n.app.themes; public class SamplePart SamplePartMessagesRegistry void 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()));

28 RRobot-DSL

29 RRobot-DSL DSL to describe Eclipse project setups

30 RRobot-DSL DSL to describe Eclipse project setups Uses Xtext

31 RRobot-DSL DSL to describe Eclipse project setups Uses Xtext Allows to setup JDT Projects PDE-Projects Bundles & Features

32 RRobot-DSL RobotTask { // Variables to be used later on variables = { ## Name of the bundle STRING "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"

33 Demo (Run Task)

34 LivePreview

35 LivePreview LivePreview was developed for FXML/FXGraph immediate feedback

36 LivePreview LivePreview was developed for FXML/FXGraph immediate feedback Expects FXML passed

37 LivePreview LivePreview was developed for FXML/FXGraph immediate feedback Expects FXML passed LivePreview requests FXML from editors who adapt to IFXMLProviderAdapter

38 Demo (Elemenatry & Lego-DSL & FXML- Viewer)

39 LivePreview public class FXMLProviderAdapter implements IFXMLProviderAdapter { private XtextEditor editor; public FXMLProviderAdapter(XtextEditor editor) { this.editor = public IEditorPart geteditorpart() { return public String getpreviewfxml() { return editor.getdocument().readonly(new IUnitOfWork<String, XtextResource>() public 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(); );

40 CSSExt-DSL

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

42 CSSExt-DSL CSS-Editor has NO hard coded properties Properties available are defined in an extra file ending with.cssext

43 CSSExt-DSL CSS-Editor has NO hard coded properties Properties available are defined in an extra file ending with.cssext CSS-Editor looks up.cssext-files from projects classpath

44 CSSExt-DSL 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;

85 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

86 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 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
