A JavaFX app for visualising the Spoon tree of Java code (Java 11 supported).
An alternative to the native GUI support of Spoon ASTs with Spoon:
$ java -cp spoon...-jar-with-dependencies.jar spoon.Launcher -i class.java --gui --noclasspath
- @arnobl
The app requires a JDK 11.
We currently do not provide any packaging of the app (jlink cannot package apps having non-modular libraries, such as Spoon).
So, to run the app, run: mvn clean package.
Then go into the target/modules folder and launch: java --module-path . --add-modules=javafx.controls,javafx.fxml,interacto.javafx,interacto.java.api,spoon.core,org.eclipse.jdt.core,annotations -jar showmeyourspoon-1.2.jar
- selection highlighting
- implicit elements masking
- export as text
- analysis level
- one argument to load a Java file
Put the code in the text area on the left. The Spoon tree should then appear (if not, maybe the code is not ok).
You can click on a tree element on the right to select the corresponding code elements on the left. This does not work when the clicked tree item refers to a code element that does not have a line position.
You can also click on a code element in the code area to select the corresponding tree item.
On the next picture, the user clicked on int:
The checkbox in the toolbar masks or shows the Java implicit elements (printed with '(implicit)' in the tree view).
The button Save exports the tree view of the current Java code in a text file.
Users can set the analysis level: auto, class element, statement, expression.
The auto level tries to detect the level automatically by starting parsing the code as a Java class (then class element, etc.):
The auto level may fail, in particular with statements or expressions.
So users can define a specific level manually.
The class element level corresponds to fields, methods, etc., of a class:
The statement level corresponds to Java code statements:
The expression level corresponds to any Java expression:
The app can take one argument: the path of a Java file to load.
