What it does

NulaCore provides code that other mods can share rather than carry their own copies. It follows the SemVer 2 specification, with versions written as major.minor.patch. Mods that use it declare a dependency on it and must target a release newer than the earlier series. The package dependencies section is required for mods that depend on it. Only the 1.1.0-alpha.2 build is published for 1.19.2, released on 2023-08-04 on the alpha channel. Both the server and every player need it, and the code is open source under the GNU Lesser General Public License v3.0 only.

Key features

  1. Shared library code

    Mods can call into NulaCore instead of bundling the same utilities, keeping each mod's size smaller.

  2. SemVer 2 versioning

    Releases use the major.minor.patch format, so dependents can tell compatible updates from breaking ones.

  3. Version constraint for dependents

    Dependent mods must require a newer NulaCore release, since earlier releases in the series are not supported.
