    Study Notes

    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.
