Moulinette Overview and Functionality

Moulinette Overview

• Moulinette is an automated system used by 42 to grade projects
• It can be used for both piscine and main cursus projects
• The goal of Moulinette is to ensure code quality and uniformity, as not all students have the same coding background
• Moulinette is triggered automatically after peer evaluations for time-boxed projects
• Moulinette runs on a dedicated VM
• The intra sends a webhook to the Moulinette program with information about the project, repo, and team
• Moulinette runs tests on the project and uploads the results to the intra and Moulinette Website
• When a project uses Moulinette it can be configured to run tests publicly for the students and staff
• Students can access their traces through email.

Tracing the Moulinette

• The trace is a log of the tests performed by Moulinette
• The trace provides information on the host system where the tests were run, including system details and compiler version
• User files are collected from Vogsphere, which contains the student's repository
• Git history for the repo is recorded, including the dates of commits and authors
• All the collected files from the repo are listed
• The trace is not always easy to understand but provides important information for debugging

Student Perspective

• Students will see a message on their project page indicating that the Moulinette is running
• When the evaluation is complete, a message with results will be displayed on the project page
• The student can see their project_mark and is notified with their trace via email if the project is configured as public trace
• Students should not assume the Moulinette is wrong if they disagree with the results
• Students should contact the pedago team for help in troubleshooting Moulinette issues

Peer Evaluation

• The 42 pedagogical system relies heavily on peer learning and peer evaluations
• Since students at 42 may have different coding levels, Moulinette is used to evaluate projects, especially during the initial projects
• Some projects, such as rushes during the main cursus, do not use peer evaluations and only rely on Moulinette

Projects with Moulinette

• Moulinette is currently used for piscine projects (except rushes) and the first three C projects in the Common Core: Libft, get_next_line, and ft_printf
• Projects with Moulinette can be identified through the project scale page on 42born2fit
• Files for Moulinette should be included and configured in the repository on 42born2fit, particularly in the scale/scale_commom.yml file

Moulinette Mark Calculation

• Moulinette results are used to calculate both the team_mark and the project_mark
• team_mark: Calculated based on eval_compilation rule, which may differ depending on the project
• project_mark: Calculated based on the final_compilation rule, with the most common rules being last_mark and best_mark

Moulinette Information Resources

• The Moulinette Website provides comprehensive information, especially about the second and third definitions of Moulinette
• The Intra & Tools Settings in the Moulinette section offers information about the Moulinette VM
• To ensure you have all the relevant information, check the specific project's documentation to understand how Moulinette is configured and used.
