# JustEnoughVCS - A Lightweight, Cross-Functional, Binary-Friendly Centralized Version Control System > **⚠️ Warning: JustEnoughVCS is currently under active development.** > > This software is in the development stage, and its features are not yet complete. ​ `JustEnoughVCS` is a lightweight version control system designed for **cross-functional teams**. It allows each member to view and organize files in a file structure **best suited to their functional role**, enabling the team to focus on content creation itself. It primarily serves collaborative scenarios involving large volumes of binary assets, such as **game development** and **multimedia design**. ## My Design Philosophy - Also My Humble Opinion 😃 ​ `JustEnoughVCS` adheres to the "**Just Enough**" philosophy, aiming to achieve collaborative security through architectural design. Centered around a **Virtual File System** and **Sheet Isolation**, it provides each creator with a focused, distraction-free workspace, making collaboration natural and simple. ![img](docs/images/FRAMEWORK_CANVAS.png) ## Virtual File System ​ The Virtual File System is the foundation of `JustEnoughVCS`. Each file is identified by a globally unique `VirtualFileId`, decoupled from its physical path. It comprehensively records: - **All historical versions** - **Description information for each modification** - **Version number sequence** - **Current latest version** - **Current file holder (the member with edit permissions)** ### Features - **Traceable History**: Easily view the history of any version and support rollback. - **Conflict-Free Collaboration**: Strictly adheres to the **"Acquire First, Edit Later"** principle. Files are **visible** to everyone but **writable** only by the holder, thus preventing conflicts. - **Pre-Acquisition Validation**: Before acquiring a file, the hash value and version number of the local file are strictly validated to ensure editing starts from the latest version. ## Sheet System ​ The Sheet System acts as a bridge connecting **virtual files** with members' **local workspaces**. It establishes a mapping from `VirtualFileId` to a local `SheetPath`, creating customized file views for each functional role (e.g., programmer, artist, designer) or individual member. Sheets are divided into two types, primarily differing in permission management: - **Reference Sheet**: Stores files commonly used across the team, serving as a shared resource library. All members can acquire files from it into their own sheets. Members can submit their own files to the Reference Sheet; after approval by an administrator, they are added to the Reference Sheet for other members to import into their own sheets. - **Member Sheet**: A member's own sheet, used to manage personal projects, tasks, and assets. The member has full management rights over the **sheet structure** (such as adding, moving mappings, etc.), but **edit rights** for the file itself remain exclusive to the file's holder, following the "Acquire First, Edit Later" principle. Typically, newly tracked files automatically grant ownership to the tracker. ### Transferring Files Between Sheets ​ Through the **Import/Export mechanism** provided by the Sheet System, members can copy a file's **mapping relationship** from one sheet to another. This mechanism transfers the file's **mapping relationship** (i.e., the binding of `VirtualFileId` to a path), not the file entity itself. The file entity always resides in the Virtual File System. This mechanism supports cross-sheet collaboration, such as submitting completed work to the team for sharing, or recommending a file to a specific member for further processing. - **Export**: A member can directly export files from their own sheet to the target sheet's (e.g., Reference Sheet or another member's sheet) pending import area. - **Import**: The owner of the target sheet receives a list of files pending import. The owner can review and selectively import them (i.e., add the mapping) into their own sheet. During this process, the file's **edit rights remain unchanged**; it simply makes the file "visible" in the recipient's sheet. This mechanism ensures the **controllability** of file transfer, as the recipient has the right to decide whether to accept the imported file mapping, thereby maintaining the cleanliness and order of their respective workspaces. ## Support Encountered any issues or have suggestions while using JustEnoughVCS? - Please submit them to the https://github.com/JustEnoughVCS/VersionControl/issues page, and we will promptly address your feedback. ## License This project is licensed under the **MIT License**.
