[v0.8.0-beta] - 2026-01-03

🔥 Sprint 1: Debug System Foundation

Debug System Improvements

• Call Stack Tracking - Added DebugFrame class for function call tracking

  • pushFrame() / popFrame() methods in DebugManager
  • Call stack visualization support
  • Depth tracking for Step Out functionality

• Step Out Implementation - Complete step-through debugging

  • stepOut() method in DebugManager
  • Exits current function and pauses at caller
  • Works with call stack depth tracking

• Code Cleanup - Production-ready debug code

  • Removed all System.err.println debug output
  • Replaced with ScriptLogger.debug() with null-safe formatting
  • Removed unused imports (HashMap, Map from DebugSession)
  • Added SLF4J-style {} placeholder formatting to ScriptLogger

🎯 Sprint 1.5: Event System Revival

Event System Fixes (2026-01-03)

• CRITICAL FIX: Event blocks now parse correctly 🔥

  • Added onEvent { } block parsing in ScriptTask
  • Events were completely broken - blocks were ignored
  • Now properly collects event script body
  • Registers directly with EventManager

• CRITICAL FIX: Events now work after script restart 🔥

  • Fixed event persistence bug when stopping/restarting scripts
  • Added registeredEvents tracking in ScriptTask
  • Events are now properly unregistered in stop() method
  • Events re-register correctly on restart()
  • Prevents duplicate/stale event handlers

• CRITICAL FIX: Events work after stop hotkey (Bug #11) 🔥

  • Fixed ScriptInterpreter.shouldStop flag blocking event execution
  • Added automatic flag reset in queueCommand() and executeQueuedCommands()
  • Events now execute correctly after pressing Z (stop all scripts)
  • Test script: test_events_after_stop.kh
  • Issue: shouldStop remained true after stopProcessing(), blocking all subsequent commands
  • Solution: Auto-reset flag when starting fresh (empty queue, not processing)
  • Documented in BUGS_FOUND.md as Bug #11

• Error Logging Improvements

  • Replaced all System.err.println with ScriptLogger in:
    • EventManager (registerEventScript, fireEvent)
    • ChatMessageMixin
    • BlockBreakMixin
    • BlockPlaceMixin
    • AttackMixin
  • Consistent error reporting across event system

Package System Foundation (2026-01-03)

• NEW: Export/Import System 🎉

  • First step towards full package system (see PACKAGE_SYSTEM_CONCEPT.md)
  • export command - share variables between scripts
  • import command - use variables from other scripts
  • ExportManager for cross-script variable sharing
  • Automatic cleanup on script stop
  • Fixed script name tracking for proper export/import resolution

• Usage Examples:

  // script1.kh
  export myVar 100
  export playerName "Kasper"
  
  // script2.kh
  import myVar from script1
  import playerName from script1
  print $myVar  // Outputs: 100
  

• Test Scripts:

  • test_export.kh - demonstrates export functionality
  • test_import.kh - demonstrates import functionality

• VSCode Extension:

  • Added export and import to command autocomplete
  • NEW: Hover Provider - hover over commands/variables to see documentation
