Release 3.0.2

A small patch to fix missing artifacts of the last 3.0.1 release compared to the previous 2.x.y release. This release only changes the Maven artifacts for the language server, so there only is a Maven release for this with no new P2 artifacts. For that, see the 3.0.1 release.
Find the Maven artifacts at the Apache repository or the Sonatype repository.

Diagram Server

• Include the META-INF/services folder of the klighd.lsp module in the published artifacts. @NiklasRentzCAU

Release 3.0.1

The next major release of KLighD is here! We skipped announcing 3.0.0 as the major release, as during the release process we noticed some issues in the Maven artifacts, so that release was never fully completed and therefore never went official.
Find the updatesite at https://kieler.github.io/KLighD/v3.0.1/ or in a single zip file below.

New Features
General

• Added new property ROUNDED_RECTANGLE_AUTOPADDING to add padding to fit the content of a node within the bounds of a rounded rectangle #165 @Eddykasp
• Added semantic filtering and tagging API #137 #129 @Eddykasp

Diagram Server

• Added support for interactive layout for ELK's MrTree algorithm #145 @soerendomroes
• Added Proxy Views #129 @fight4day @Eddykasp @NiklasRentzCAU Proxies are simplified renderings that can be added to graph elements via the PROXY_VIEW_PROXY_RENDERING property that will be shown on the border of the screen in klighd-vscode-based applications to indicate connections to off-screen elements in a non-obstructive way.

Removals

Diagram Server

• breaking Split up the standalone plugin into a standalone plugin with the same behavior and a setup plugin containing the setup of KLighD from standlone, without the Piccolo exporter. This enables the use of standalone as an artifact with the capability for off-screen rendering applications, while language-server-based applications use the setup plugin instead, to avoid the unneeded dependency. Requires language server applications to switch their standalone dependency for the setup dependency and update the de.cau.cs.kieler.klighd.standalone.KlighdStandaloneSetup import for the new de.cau.cs.kieler.klighd.setup.KlighdStandaloneSetup import. #190 @NiklasRentzCAU
• Changed ID generation for diagram/rendering elements for consistent and predictable instead of random IDs #174 @NiklasRentzCAU
• Fixed handling of non-expanded graphs in ID generation/micro layout calculation in the language server #188 @NiklasRentzCAU
• Re-structured interactive layout with ELK #145 @soerendomroes @Drakae
• Update to Sprotty 1.1.1 #182 #183 @NiklasRentzCAU

Release 2.3.0

as well as more small fixes for Eclipse and Diagram server behavior.

The new Maven artifacts
The newly published Maven artifacts have the goal to make builds using the diagram server and KLighD's offscreen exporters in a more natural way, by using simple Maven/Gradle dependencies instead of previously used hacky workarounds. Currently the artifacts are mainly built for these two use cases, other use cases might work as well, but you might have to beware of dependency management yourself:

First of all, most of the packages except de.cau.cs.kieler.klighd.standalone and de.cau.cs.kieler.klighd.lsp do not list their dependencies, therefore requiring dependency management by the dependent applications using only the other packages. E.g., some application just creating some KGraphs and use none of the other features will have to include more dependencies. We think this will not be a problem, as non-Eclipse applications always should use either one of the standalone/lsp packages.

Currently the de.cau.cs.kieler.klighd.standalone package works as an entry point for offscreen exporter applications with all dependencies as a bill of materials (BOM) contained in this package.
NOTE: If you only have a dependency on the standalone package, you might need to manually resolve the SWT dependencies if you want to use e.g. some diagram exporter using SWT, see #164. Otherwise if you do not need SWT you may exclude it as shown below and add a dependency to de.cau.cs.kieler.swt.mock:org.eclipse.swt and alike.

For diagram servers, the de.cau.cs.kieler.klighd.lsp package works as another BOM for language server-based applications. Here, the occurrences of org.eclipse.swt, org.eclipse.jface and some occurrences of org.eclipse.ui are being replaced by mock code only providing required API but no functionality. Because of legacy reasons SWT usually is deeply integrated into KLighD's core, but its code is never used in the language server case. As SWT usually introduces platform-dependent packages, this replacement with the mock code makes language servers platform-independent and more leightweight.

If you explicitly use some other KLighD packages in your diagram server application, you therefore might need to also exclude the "real" SWT etc. packages in favor of the mock. An example exclusion in a Maven pom.xml build might look like this:

<dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>de.cau.cs.kieler.klighd</groupId>
        <artifactId>de.cau.cs.kieler.klighd</artifactId>
        <version>${klighd-version}</version>
        <exclusions>
          <exclusion>
            <groupId>org.eclipse.platform</groupId>
            <artifactId>org.eclipse.swt</artifactId>
          </exclusion>
          <exclusion>
            <groupId>org.eclipse.platform</groupId>
            <artifactId>org.eclipse.ui.workbench</artifactId>
          </exclusion>
          <exclusion>
            <groupId>org.eclipse.platform</groupId>
            <artifactId>org.eclipse.jface</artifactId>
          </exclusion>
        </exclusions>
      </dependency>
       [...]
    </dependencies>
  </dependencyManagement>

Release 2.0.0

A new major release of KLighD including some bugfixes, adaptions to newer versions and new features!
Find the updatesite at https://kieler.github.io/KLighD/v2.0.0/ or in a single zip file below.

New Features

• Language Server support added to allow displaying diagrams using the KLighD framework within other use-cases as an extendable standalone non-Eclipse Application using Sprotty. See #49 and the new de.cau.cs.kieler.klighd.lsp bundle. Further details also on https://github.com/eclipse/sprotty and https://rtsys.informatik.uni-kiel.de/confluence/display/KIELER/KEITH
• In addition to Extension Points, extensions are now also allowed to be registered via Java Service Loader to allow for non-Eclipse execution #50
• Added Extension Point/Java Service 'startupHook' that will load on startup of KLighD and can be used to register all KLighD extensions in a single place programatically without having to bother with registering every syntheses, action, etc. via extension point and as a Java Service every time. Only this new extension has to be registered once via extension point and in a META-INF/services/de.cau.cs.kieler.klighd.IKlighdStartupHook file.

Changes and Bugfixes

• KLighD now uses Eclipse 2020-06, ELK 0.7.0, Xtext 2.22, and has a new requirement to Sprotty 0.9.0 for the language server bundles.
• Some non-Eclipse- and non-UI specific components have been refactored into own *.ide Plug-Ins. This includes syntheses, actions and some other stuff. See #41,#42
• Added unique identifier to SynthesisOptions
• Improved incremental update to preserve the order of elements, see #1, #48
• Made incremental update more robust to non-standard and modified graphs.
• Fixed the dash pattern in KLineStyles #18
• Improved texts in SVG export #44
• Allow multiple KTexts per KLabel #55
• More minor bugfixes.
