ClickSorted 1.0.0

ClickSorted 1.0.0 is a ground-up modernization of the original ClickSort plugin,
rewritten for Paper 1.21.x with a clean architecture and no legacy dependencies.

Highlights

• New package & name — rebranded from ClickSort (me.desht.clicksort) to ClickSorted
  (net.kccricket.clicksorted) with a fully reorganized, concern-based package layout.
• No more SQLite — player sorting preferences are now stored in Bukkit's Persistent Data
  Container; no database file, no async JDBC, no migration needed.
• Paper-native commands — the old dhutils AbstractCommand / CommandManager framework
  is gone; commands are a Brigadier tree registered via LifecycleEvents.COMMANDS.
• Adventure / MiniMessage messages — all user-facing text is now an Adventure Component;
  legacy § color codes are fully replaced and lang.yml uses MiniMessage format throughout.
• Full integration test suite — 10 test classes covering sort behavior, commands, config
  reload, cooldown messaging, player prefs, and resource updating via MockBukkit.

New Features

Add-only config merging

ResourceUpdater performs an add-only merge of bundled defaults into the plugin data
folder on startup. New keys added in a future release appear in your live config
automatically; existing customizations are never overwritten.

Expanded sortable inventory types

config.yml now includes additional inventory types (barrel, blast furnace,
dispenser, dropper, furnace, hopper, smoker) in the default sortable_inventories
list so more containers sort out of the box.

Updated item groups

groups.yml has been updated to reflect the full 1.21.5 creative-mode tab groupings,
giving GROUP sort a more intuitive ordering for current-version items.

Bug Fixes

• SortEngine null/empty-inventory edge cases hardened — operations on inventories
  with no sortable slots no longer throw.
• InventorySortEvent defensive guard — the post-sort event is only fired when a sort
  actually occurs, preventing spurious third-party handler calls.
• LangConfig missing-key fallback — referencing an undefined message key now returns
  a safe placeholder instead of throwing a NullPointerException.

Other Improvements

• Build system — migrated from Maven (pom.xml) to Gradle (build.gradle.kts) with
  the Shadow plugin for fat-JAR assembly.
• Java 21 bytecode target — the build now emits Java 21 class files, matching the
  minimum JVM required by modern Paper builds.
• Removed dhutils — the entire embedded me.desht.dhutils library (≈3 000 lines) is
  gone; only the handful of utilities actually used by the plugin were rewritten as
  focused classes (Log, ItemNames, CooldownMessenger, Permissions).
• Removed Essentials integration — the VALUE sort method (which relied on Essentials
  item worth data) has been removed; NAME and GROUP remain.
• Removed coloured_console setting — console output is always plain text; the
  config key had no effect on modern Paper and is no longer present.
• Removed legacy version compatibility shims — version-parsing workarounds for
  Minecraft 1.12 and earlier are gone.
• Unified config lifecycle — all four config files (config.yml, lang.yml,
  groups.yml, items.yml) are managed through a single ConfigManager; reload via
  /clicksorted reload refreshes all of them atomically.
• Typed debug levels — DebugLevel is now an enum (OFF, LOW, MEDIUM, HIGH)
  replacing the old integer-based debug flag, with log calls gated by level comparison.
• Documented YAML configs — all four bundled resource files now have inline comments
  explaining every key.
• Expanded README — covers installation, permissions, commands, configuration
  reference, and the GROUP sort method.

Compatibility

✔️ Paper/Folia 1.20.6+
✔️ Java 21

Upgrading from ClickSort (original fork)

1. Stop your server.
2. Remove the old ClickSort jar from plugins/.
3. Place clicksorted-1.0.0.jar in plugins/.
4. Start your server. Fresh config.yml, lang.yml, groups.yml, and items.yml
   files will be generated in plugins/ClickSorted/.
5. (Optional) Review your old plugins/ClickSort/ settings and migrate any
   customizations to the new config files. Note that player sorting preferences
   were stored in SQLite and cannot be migrated; players will start with defaults.
