NilLoader | The universally-compatible ultra-light mod loader

NilLoader is a Java library. NilLoader has no bugs, it has no vulnerabilities, it has build file available, it has a Weak Copyleft License and it has low support. You can download it from GitHub.

NilLoader (ØL or 0L) is a minimal, easy-to-install, application-independent system for applying runtime patches to programs written in Java, compatible with any launcher that allows you to modify JVM arguments. It's based on the native Java agent system, but provides a comprehensive and convenient API for defining class patches and entrypoints on top of it. It additionally provides a system for working with obfuscated environments, without forcing you to write code using obfuscated names. (Note that NilLoader does not provide a "high-level" bytecode patching system like Mixin; you have to write raw bytecode patches using Mini or ASM directly.). A NilLoader mod includes a complete copy of NilLoader within itself, allowing a NilLoader mod to be used directly as a Java agent. However, you can also load NilLoader alone as a Java agent, and it will discover NilLoader-compatible jars in a subdirectory called mods, or nilmods if another loader is being layered with NilLoader and is confused by the presence of NilLoader jars in its mods directory. Copies of NilLoader contained in these mods will be ignored by the class loader, avoiding version conflicts.
