# Java Automatic Feedback

Rascal implementation of a simple rule checker for student Java assignments.

## How to run

1. Download the latest rascal-shell-unstable.jar from the rascal website and
   put it next to the run.sh script
   http://update.rascal-mpl.org/console/rascal-shell-unstable.jar

1. Run the script

        $ ./run.sh <two-digit-assignment-nr> <absolute-path-to-student-project>
   
   For example

        $ ./run.sh 02 /home/mkl/radboud/teaching/object-orientation/oo-grading-2019/assignment02/thout/70827-16116\ -\ Asgn\ CS\ Group\ 125\ -\ Jordy\ Schoolmeesters\ -\ Feb\ 10\,\ 2019\ 22_55/
        Version: 0.13.0-SNAPSHOT
        error("All I/O should happen in the view class",|java+class:///a2/Gallows|)
        error("Always explicitly specify access modifiers: public, protected, or private",|java+field:///a2/User/input|)


## Running the test cases

There are some test projects and test cases to check that the rules give
correct error messages. To run the tests, use the test script. The test script
looks for all files `*Spec.rsc` and executes them

        $ ./test.sh

To run only specific files, specify them on the command line.

        $ ./test.sh Assignment02RulesSpec.rsc Assignment03RulesSpec.rsc
