File Structure Setup (Tentative)

Nebula aims to provide users with an information preserving structure for storing files. The application will use this structure to generate a full distribution.json for HeliosLauncher. For coherency, the distribution structure is modularized and encapsulated by a directory pattern. These encapsulations will be explained below. They can be generated manually or by using the commands documented above.

Distribution Encapsulation

The distribution object is represented by the main root. All command output will be stored in this directory. The structure is documented below.

Ex.

• TestRoot The root directory which encapsulates the distribution.
  • servers All server files are stored in this directory.

Server Encapsulation

Server objects are encapsulated in their own folders. The name of the server's folder contains both its id and version.

Ex.

• servers
  • TestServer-1.12.2 A server with id TestServer set to version 1.12.2.

The server directory will contain files pertaining to that server.

Ex.

• TestServer-1.12.2
  • files All modules of type File.
  • forgemods All modules of type ForgeMod.
  • litemods All modules of type LiteMod.
  • TestServer-1.12.2.png Server icon file.
