[Feature Request] Mod Support

[Diyagi]

Since im lacking time to work on this i will leave it in here in case anyone wants to fiddle with it.
Implementing mod support for the container is possible, the idea i had in mind was to:

1. Mod Specification Using Environment Variables

Mods can be specified through an environment variable, using the format:
mod-id:version

• Example: core-lib:3.2.1
• Key Details:
  • The version can be omitted to default to the latest version of the mod.
  • Multiple mods can be specified as a comma-separated list:
    core-lib:3.2.1,corelibentity:4.0.4,corelibresources,corelibcommands:3.2.1

---

2. Downloading Mods from Mod.io

• Mods will be downloaded using the Mod.io API.
• An API key is required and must be supplied by the user via an environment variable.
  • Note: While mods can technically be downloaded from Mod.io without an API key, doing so violates their Terms of Service (TOS).

---

3. Handling Downloaded Mods

• Mods downloaded from Mod.io are provided in a compressed format (ZIP).
• The container must:
  1. Uncompress the mods into a specific folder.
  2. Each mod’s files should be placed in a folder named after its mod-id.
     • For example, if the mod ID is core-lib, its files should go into:
       <target-folder>/core-lib/
  3. The target folder should be specified by an environment variable (already declared in the Dockerfile).

---

4. Managing Mod Updates

The container should be able to identify and manage mod updates:

• Since the mod version is not specified in its manifest, a local file should be maintained.
  • This file will list all installed mods along with their versions.
• When updating mods:
  • Mods in the environment variable list are updated to the specified or latest version.
  • Any mods not in the list should be deleted to avoid conflicts or redundancy.

---

5. Optional: Dependency Resolution

• Dependency resolution is possible but complex to implement.
  • The Mod.io API provides information on mod dependencies:
    Get Mod Dependencies
• Consider adding this feature for advanced mod compatibility. However, it may require significant effort and careful handling of dependencies.
