If there are questions regarding the exercise, please refer to Johannes Mey at [email protected]. However, before asking questions, please read the JastAdd reference manual:
This exercise uses gradle to get dependencies and build and test its solutions.
Gradle is bundled for Linux/Mac and Windows and the bundled version should be
used with ./gradlew or gradlew.bat, respectively.
The following gradle tasks are helpful to solve the tasks:
runruns the main method in classde.tudresden.inf.st.most.ExerciseMaintestruns the tests. There are tests that should succeed after a particular task has been solved.DrASTis an editor that displays syntax trees. It can be used to load and displayjsonorexpfiles. Attribute values and reference attribute references are shown.RagDollis a javadoc variant for JastAdd.
All JastAdd files that must be edited are in the src/main/jastadd folder. The contents are as follows:
expressions.astis the grammarexpressions.flexcontains the jflex lexer specificationexpressions.parsercontains the beaver parser specificationPrinting.jragcontains the pretty-printerNameResolution.jragshould contain the name resolutionEvaluation.jragshould contain an evaluation attributeOptimization.jragshould contain the rewrites and their helper attributesAnalysis.jragshould contain the unused definitions attributeASTPrinting.jaddcontains helper methods to display the AST
Additionally, the main class de.tudresden.inf.st.most.ExerciseMain can be
modified to test the code. Please be careful when editing, because DrAST
relies on a certain structure (in particular, on field DrAST_root_node
containing an AST root node).
No additional help is given for editing the lexer and parser specifications as this is more or less trivial copy-and-paste. If more help is required, please refer to the websites:
Please submit src/main/ and its subfolders.
