Information

This PR closes an internal goal.

Details

Proposed feature:

This implements two separate features (may be split into separate PRs later down the line):

• Introduce command trees, which allow for nested subcommands to be declared and parsed effectively.
  • Goals: lightweight, incrementally adoptable across new and existing commands as necessary
  • Trees consist of a root node, literal nodes and execute nodes
  • No parsing of argument types is implemented at present
  • Possibly worth exploring cloud/another tree command lib instead of rolling our own
  • Provide helper methods on command exec context to replicateEssentialsCommand
  • Think about command node impl in more depth
• Rewrite/essentials, splitting complex subcommands into separate classes
  • Replacerun andtabComplete impls with tree
  • Refactor existing subcommand functions
  • Split out dump into own class (possibly a separate refactor on its own?)

Environments tested:

OS: Windows 11 22H2

Java version: Eclipse Temurin 17.0.6

• Most recent Paper version (1.19.4, git-Paper-547)
• CraftBukkit/Spigot/Paper 1.12.2
• CraftBukkit 1.8.8

Demonstration:

This PR should preserve all existing functionality of/essentials.
