This repository contains files to connect the Moodle Coderunner Plugin with the etutor++ system.

ace-editor Contains files to extend the syntax highlighting of the Ace editor that is used by the plugin. Currently a mode for Relational Algebra questions is provided.

jobeinabox Contains files for the customer docker image of jobeinabox, the Jobe server required for the plugin. This custom image has the correct timezone set by the default, the requests python module already installed, and the number of simultaneous jobs that the jobe server will process can be set as a build-argument during the build-process of the image. Also, a kubernetes configuration (coming soon) is provided, that defines a deployment and a service for the jobe server.

1. Paste the desired mode-*.js file into the plugin directory, under /ace.
2. Adjust the following files:

• /ace/ext-prompt.js
• /ace/ext-settings_menu.js
• /ace/ext-options.js
• /ace/ext-modelist.js

by adding the following entry to the supportedModes dictionary (example for Relational Algebra):

RelAlg: ["relalg"]

3. Purge the caches in Moodle under Site Administration -> Development -> Purge Caches
4. When creating a Coderunner question, under Advanced Customisation, set the Ace Language accodordingly, e.g. relalg.

1. Start with an already existing mode and adjust it accordingly.

1. After installing the plugin, you might have to change the Moodle security settings to enable communication with the Jobe server.
2. Install the requests module on your Jobe server using pip (or use the custom image).
3. Add a Coderunner question to the question bank.

• Use python3 as question type.
• Under Customisation, add the template.
• Choose a template grader with the result columns [["Kriterium", "criterion"],["Ergebnis", "result", "%h"]].
• Under advanced customisation, set the question as prototype and set the name, e.g. etutor.

4. Create a question based upon the new prototype.

• As question type, choose the newly created prototype.
• Under Coderunner question type choose Customise.
• Enable Precheck (Selected) and tick Hide check.
• Choose an All-or-nothing-grading with a penalty regime of 0.
• As template params, add the following JSON: { "EXERCISE_ID": 13598, "DIAGNOSE_LEVEL": 0, "TASK_TYPE": "sql" } Note: Replace the id with the disptacherId of an exisitng question in the eTutor++ platform and change the task_type (has to match dispatcher task types).
• Under advanced customisation, set the Ace Language accordingly.
• Under Answer, add the correct solution (choose Validate on save if you want to).
• Under Test Cases, add two test cases. Each test-case is defined by the Standard Input that sets the mode for the evaluation by the dke-dispatcher. Create one test-case for Preckeck only with the input 'run'. Create another test-case for Check Only with the input 'submit'.

5. Use the Preview function at the bottom to verify if everything works.

Tipp: For each question type (e.g. SQL) you can create one question that can be used as a template. For further questions of the same type, you can duplicate this question and only replace the disptacher-id of the question, the correct solution and question text.
