A preview of the pure Java version of VisualLangLab is now available. The GUI, and other characteristics, are virtually identical to the previous version, but the JAR file is very much smaller as it does not bundle the Scala API jars.
A preview of the pure Java version of VisualLangLab is available here . The GUI, and other characteristics, remain virtually unchanged (see documentation ), but the download is very much smaller as it does not bundle the entire Scala API. The preview does not yet support packrat parsing, and an API for application programs is not yet available. All grammar development and testing features are however available.
The reduction in jar-file size was achieved by rewriting in Java the elements of the Scala API actually used (and not bundling entire jar files). This pure Java version will differ from the previous version in the following ways:
- Minor changes to the AST structure.
- The AST is described in terms of Java/JVM data-structures.
- The API will support application programming in all JVM languages uniformly (including Scala).
The documentation, examples, and sample-code all remain applicable with no (or very minor) changes. You can get the preview version here . To start VisualLangLab Java version, just download and double-click the VLL4J.jar file.
