This commit enables McRogueFace to compile without SFML dependencies
when built with -DMCRF_HEADLESS, a prerequisite for Emscripten/WebAssembly
support.
Changes:
- Add src/platform/HeadlessTypes.h (~900 lines of SFML type stubs)
- Consolidate all SFML includes through src/Common.h (15 files fixed)
- Wrap ImGui-SFML with #ifndef MCRF_HEADLESS guards
- Disable debug console/explorer in headless builds
- Add comprehensive research document: docs/EMSCRIPTEN_RESEARCH.md
The headless build compiles successfully but uses stub implementations
that return failure/no-op. This proves the abstraction boundary is clean
and enables future work on alternative backends (VRSFML, Emscripten).
What still works in headless mode:
- Python interpreter and script execution
- libtcod integrations (pathfinding, FOV, noise, BSP, heightmaps)
- Timer system and scene management
- All game logic and data structures
Build commands:
Normal: make
Headless: cmake .. -DCMAKE_CXX_FLAGS="-DMCRF_HEADLESS" && make
Addresses #158

Enables background Python threads to safely modify UI objects by
synchronizing with the render loop at frame boundaries.
Implementation:
- FrameLock class provides mutex/condvar synchronization
- GIL released during window.display() allowing background threads to run
- Safe window opens between frames for synchronized UI updates
- mcrfpy.lock() context manager blocks until safe window, then executes
- Main thread detection: lock() is a no-op when called from callbacks
or script initialization (already synchronized)
Usage:
import threading
import mcrfpy
def background_worker():
with mcrfpy.lock(): # Blocks until safe
player.x = new_x # Safe to modify UI
threading.Thread(target=background_worker).start()
The lock works transparently from any context - background threads get
actual synchronization, main thread calls (callbacks, init) get no-op.

Implement the foundational HeightMap class for procedural generation:
- HeightMap(size, fill=0.0) constructor with libtcod backend
- Immutable size property after construction
- Scalar operations returning self for method chaining:
- fill(value), clear()
- add_constant(value), scale(factor)
- clamp(min=0.0, max=1.0), normalize(min=0.0, max=1.0)
Includes procedural generation spec document and unit tests.

McRogueFace needs to accept callable objects (properties on C++ objects)
and also support subclassing (getattr on user objects). Only direct
properties were supported previously, now shadowing a callback by name
will allow custom objects to "just work".
- Added CallbackCache struct and is_python_subclass flag to UIDrawable.h
- Created metaclass for tracking class-level callback changes
- Updated all UI type init functions to detect subclasses
- Modified PyScene.cpp event dispatch to try subclass methods
Major Timer API improvements:
- Add `stopped` flag to Timer C++ class for proper state management
- Add `start()` method to restart stopped timers (preserves callback)
- Add `stop()` method that removes from engine but preserves callback
- Make `active` property read-write (True=start/resume, False=pause)
- Add `start=True` init parameter to create timers in stopped state
- Add `mcrfpy.timers` module-level collection (tuple of active timers)
- One-shot timers now set stopped=true instead of clearing callback
- Remove deprecated `setTimer()` and `delTimer()` module functions
Timer callbacks now receive (timer, runtime) instead of just (runtime).
Updated all tests to use new Timer API and callback signature.

Replace module-level audio functions with proper OOP API:
- mcrfpy.Sound: Wraps sf::SoundBuffer + sf::Sound for short effects
- mcrfpy.Music: Wraps sf::Music for streaming long tracks
- Both support: volume, loop, playing, duration, play/pause/stop
- Music adds position property for seeking
Add mcrfpy.keyboard singleton for real-time modifier state:
- shift, ctrl, alt, system properties (bool, read-only)
- Queries sf::Keyboard::isKeyPressed() directly
Add mcrfpy.__version__ = "1.0.0" for version identity
Remove old audio API entirely (no deprecation - unused in codebase):
- createSoundBuffer, loadMusic, playSound
- setMusicVolume, getMusicVolume, setSoundVolume, getSoundVolume

Implements ColorLayer and TileLayer classes with z_index ordering:
- ColorLayer: stores RGBA color per cell for overlays, fog of war, etc.
- TileLayer: stores sprite index per cell with optional texture
- z_index < 0: renders below entities
- z_index >= 0: renders above entities
Python API:
- grid.add_layer(type, z_index, texture) - create layer
- grid.remove_layer(layer) - remove layer
- grid.layers - list of layers sorted by z_index
- grid.layer(z_index) - get layer by z_index
- layer.at(x,y) / layer.set(x,y,value) - cell access
- layer.fill(value) - fill entire layer
Layers are allocated separately from UIGridPoint, reducing memory
for grids that don't need all features. Base grid retains walkable/
transparent arrays for TCOD pathfinding.

Replace deprecated Python C API calls with modern PyConfig-based initialization:
- PySys_SetArgvEx() -> PyConfig.argv (deprecated since 3.11)
- Py_InspectFlag -> PyConfig.inspect (deprecated since 3.12)
Fix critical memory safety bugs discovered during migration:
- PyColor::from_arg() and PyVector::from_arg() now return new references
instead of borrowed references, preventing use-after-free when callers
call Py_DECREF on the result
- GameEngine::testTimers() now holds a local shared_ptr copy during
callback execution, preventing use-after-free when timer callbacks
call delTimer() on themselves
Fix double script execution bug with --exec flag:
- Scripts were running twice because GameEngine constructor executed them,
then main.cpp deleted and recreated the engine
- Now reuses existing engine and just sets auto_exit_after_exec flag

- Add --continue-after-exceptions CLI flag to preserve old behavior
- Update exception handlers in Timer, PyCallable, and Animation
- Signal game loop via McRFPy_API atomic flags

Fixed module-level docstring in PyModuleDef where double-backslash newlines
(\\n) were appearing as literal "\n" text in help(mcrfpy) output.
Changed from escaped newlines (\\n) to actual newlines (\n) so the C compiler
interprets them correctly.
Before: help(mcrfpy) showed "McRogueFace Python API\\n\\nCore game..."
After: help(mcrfpy) shows proper formatting with line breaks
The issue was in the PyDoc_STR() macro call - it doesn't interpret escape
sequences, so the string literal itself needs to have proper newlines.

commit 70c71565c684fa96e222179271ecb13a156d80ad
Fix UI object segfault by switching from managed to manual weakref management
The UI types (Frame, Caption, Sprite, Grid, Entity) were using
Py_TPFLAGS_MANAGED_WEAKREF while also trying to manually create weakrefs
for the PythonObjectCache. This is fundamentally incompatible - when
Python manages weakrefs internally, PyWeakref_NewRef() cannot access the
weakref list properly, causing segfaults.
Changed all UI types to use manual weakref management (like PyTimer):
- Restored weakreflist field in all UI type structures
- Removed Py_TPFLAGS_MANAGED_WEAKREF from all UI type flags
- Added tp_weaklistoffset for all UI types in module initialization
- Initialize weakreflist=NULL in tp_new and init methods
- Call PyObject_ClearWeakRefs() in dealloc functions
This allows the PythonObjectCache to continue working correctly,
maintaining Python object identity for C++ objects across the boundary.
Fixes segfault when creating UI objects (e.g., Caption, Grid) that was
preventing tutorial scripts from running.
This is the bulk of the required behavior for Issue #126.
that issure isn't ready for closure yet; several other sub-issues left.

Refactor timer system for cleaner architecture and enhanced functionality
Major improvements to the timer system:
- Unified all timer logic in the Timer class (C++)
- Removed PyTimerCallable subclass, now using PyCallable directly
- Timer objects are now passed to callbacks as first argument
- Added 'once' parameter for one-shot timers that auto-stop
- Implemented proper PythonObjectCache integration with weakref support
API enhancements:
- New callback signature: callback(timer, runtime) instead of just (runtime)
- Timer objects expose: name, interval, remaining, paused, active, once properties
- Methods: pause(), resume(), cancel(), restart()
- Comprehensive documentation with examples
- Enhanced repr showing timer state (active/paused/once/remaining time)
This cleanup follows the UIEntity/PyUIEntity pattern and makes the timer
system more Pythonic while maintaining backward compatibility through
the legacy setTimer/delTimer API.

commit 145834cfc31b8dabc4cb3591b9cb4ed99fc8b964
Implement Python object cache to preserve derived types in collections
Add a global cache system that maintains weak references to Python objects,
ensuring that derived Python classes maintain their identity when stored in
and retrieved from C++ collections.
Key changes:
- Add PythonObjectCache singleton with serial number system
- Each cacheable object (UIDrawable, UIEntity, Timer, Animation) gets unique ID
- Cache stores weak references to prevent circular reference memory leaks
- Update all UI type definitions to support weak references (Py_TPFLAGS_MANAGED_WEAKREF)
- Enable subclassing for all UI types (Py_TPFLAGS_BASETYPE)
- Collections check cache before creating new Python wrappers
- Register objects in cache during __init__ methods
- Clean up cache entries in C++ destructors
This ensures that Python code like:
```python
class MyFrame(mcrfpy.Frame):
def __init__(self):
super().__init__()
self.custom_data = "preserved"
frame = MyFrame()
scene.ui.append(frame)
retrieved = scene.ui[0] # Same MyFrame instance with custom_data intact
```
Works correctly, with retrieved maintaining the derived type and custom attributes.

Fix animation callback crashes from iterator invalidation (#119)
Resolved segfaults caused by creating new animations from within
animation callbacks. The issue was iterator invalidation in
AnimationManager::update() when callbacks modified the active
animations vector.
Changes:
- Add deferred animation queue to AnimationManager
- New animations created during update are queued and added after
- Set isUpdating flag to track when in update loop
- Properly handle Animation destructor during callback execution
- Add clearCallback() method for safe cleanup scenarios
This fixes the "free(): invalid pointer" and "malloc(): unaligned
fastbin chunk detected" errors that occurred with rapid animation
creation in callbacks.
commit eb88c7b3aa
Add animation completion callbacks (#119)
Implement callbacks that fire when animations complete, enabling direct
causality between animation end and game state changes. This eliminates
race conditions from parallel timer workarounds.
- Add optional callback parameter to Animation constructor
- Callbacks execute synchronously when animation completes
- Proper Python reference counting with GIL safety
- Callbacks receive (anim, target) parameters (currently None)
- Exception handling prevents crashes from Python errors
Example usage:
```python
def on_complete(anim, target):
player_moving = False
anim = mcrfpy.Animation("x", 300.0, 1.0, "easeOut", callback=on_complete)
anim.start(player)

Fix animation segfaults with RAII weak_ptr implementation
Resolved two critical segmentation faults in AnimationManager:
1. Race condition when creating multiple animations in timer callbacks
2. Exit crash when animations outlive their target objects
Changes:
- Replace raw pointers with std::weak_ptr for automatic target invalidation
- Add Animation::complete() to jump animations to final value
- Add Animation::hasValidTarget() to check if target still exists
- Update AnimationManager to auto-remove invalid animations
- Add AnimationManager::clear() call to GameEngine::cleanup()
- Update Python bindings to pass shared_ptr instead of raw pointers
This ensures animations can never reference destroyed objects, following
proper RAII principles. Tested with sizzle_reel_final.py and stress
tests creating/destroying hundreds of animated objects.

docs: cancel PyPI wheel task and add future vision for Python extension architecture
Task #70 Analysis:
- Discovered fundamental incompatibility with PyPI distribution
- McRogueFace embeds CPython rather than being loaded by it
- Traditional wheels expect to extend existing Python interpreter
- Current architecture is application-with-embedded-Python
Decisions:
- Cancelled PyPI wheel preparation as out of scope for Alpha
- Cleaned up attempted packaging files (pyproject.toml, setup.py, etc.)
- Identified better distribution methods (installers, package managers)
Added Future Vision:
- Comprehensive plan for pure Python extension architecture
- Would allow true "pip install mcrogueface" experience
- Requires major refactoring to invert control flow
- Python would drive main loop with C++ performance extensions
- Unscheduled but documented as long-term possibility
This clarifies the architectural boundaries and sets realistic
expectations for distribution methods while preserving the vision
of what McRogueFace could become with significant rework.
Author: John McCardle <mccardle.john@gmail.com>

docs: update ROADMAP with PyArgHelpers infrastructure completion
Author: John McCardle <mccardle.john@gmail.com>
refactor: implement PyArgHelpers for standardized Python argument parsing
This major refactoring standardizes how position, size, and other arguments
are parsed across all UI components. PyArgHelpers provides consistent handling
for various argument patterns:
- Position as (x, y) tuple or separate x, y args
- Size as (w, h) tuple or separate width, height args
- Grid position and size with proper validation
- Color parsing with PyColorObject support
Changes across UI components:
- UICaption: Migrated to PyArgHelpers, improved resize() for future multiline support
- UIFrame: Uses standardized position parsing
- UISprite: Consistent position handling
- UIGrid: Grid-specific position/size helpers
- UIEntity: Unified argument parsing
Also includes:
- Improved error messages for type mismatches (int or float accepted)
- Reduced code duplication across constructors
- Better handling of keyword/positional argument conflicts
- Maintains backward compatibility with existing API
This addresses the inconsistent argument handling patterns discovered during
the inheritance hierarchy work and prepares for Phase 7 documentation.
Author: John McCardle <mccardle.john@gmail.com>
feat(Python): establish proper inheritance hierarchy for UI types
All UIDrawable-derived Python types now properly inherit from the Drawable
base class in Python, matching the C++ inheritance structure.
Changes:
- Add Py_TPFLAGS_BASETYPE to PyDrawableType to allow inheritance
- Set tp_base = &mcrfpydef::PyDrawableType for all UI types
- Add PyDrawable.h include to UI type headers
- Rename _Drawable to Drawable and update error message
This enables proper Python inheritance: Frame, Caption, Sprite, Grid,
and Entity all inherit from Drawable, allowing shared functionality
and isinstance() checks.
Author: John McCardle <mccardle.john@gmail.com>
refactor: move position property to UIDrawable base class (UISprite)

refactor: move position property to UIDrawable base class (UIFrame)
- Add position member to UIDrawable base class
- Add common position getters/setters (x, y, pos) to base class
- Update UIFrame to use base class position instead of box position
- Synchronize box position with base class position for rendering
- Update all UIFrame methods to use base position consistently
- Add comprehensive test coverage for UIFrame position handling
This is part 1 of moving position to the base class. Other derived classes
(UICaption, UISprite, UIGrid) will be updated in subsequent commits.
Author: John McCardle <mccardle.john@gmail.com>
refactor: remove UIEntity collision_pos field
- Remove redundant collision_pos field from UIEntity
- Update position getters/setters to use integer-cast position when needed
- Remove all collision_pos synchronization code
- Simplify entity position handling to use single float position field
- Add comprehensive test coverage proving functionality is preserved
This removes technical debt and simplifies the codebase without changing API behavior.
Author: John McCardle <mccardle.john@gmail.com>
feat: add PyArgHelpers infrastructure for standardized argument parsing
- Create PyArgHelpers.h with parsing functions for position, size, grid coordinates, and color

docs: mark Phase 6 (Rendering Revolution) as complete
Phase 6 is now complete with all core rendering features implemented:
Completed Features:
- Grid background colors (#50) - customizable backgrounds with animation
- RenderTexture overhaul (#6) - UIFrame clipping with opt-in architecture
- Viewport-based rendering (#8) - three scaling modes with coordinate transform
Strategic Decisions:
- UIGrid already has optimal RenderTexture implementation for its viewport needs
- UICaption/UISprite clipping deemed unnecessary (no children to clip)
- Effects/Shader/Particle systems deferred to post-Phase 7 for focused delivery
The rendering foundation is now solid and ready for Phase 7: Documentation & Distribution.
Author: John McCardle <mccardle.john@gmail.com>
feat(viewport): complete viewport-based rendering system (#8)
Implements a comprehensive viewport system that allows fixed game resolution
with flexible window scaling, addressing the primary wishes for issues #34, #49, and #8.
Key Features:
- Fixed game resolution independent of window size (window.game_resolution property)
- Three scaling modes accessible via window.scaling_mode:
- "center": 1:1 pixels, viewport centered in window
- "stretch": viewport fills window, ignores aspect ratio
- "fit": maintains aspect ratio with black bars
- Automatic window-to-game coordinate transformation for mouse input
- Full Python API integration with PyWindow properties
Technical Implementation:
- GameEngine::ViewportMode enum with Center, Stretch, Fit modes
- SFML View system for efficient GPU-based viewport scaling
- updateViewport() recalculates on window resize or mode change
- windowToGameCoords() transforms mouse coordinates correctly
- PyScene mouse input automatically uses transformed coordinates
Tests:
- test_viewport_simple.py: Basic API functionality
- test_viewport_visual.py: Visual verification with screenshots
- test_viewport_scaling.py: Interactive mode switching and resizing
This completes the viewport-based rendering task and provides the foundation
for resolution-independent game development as requested for Crypt of Sokoban.

Author: John McCardle <mccardle.john@gmail.com>
fix: improve click handling with proper z-order and coordinate transforms
- UIFrame: Fix coordinate transformation (subtract parent pos, not add)
- UIFrame: Check children in reverse order (highest z-index first)
- UIFrame: Skip invisible elements entirely
- PyScene: Sort elements by z-index before checking clicks
- PyScene: Stop at first element that handles the click
- UIGrid: Implement entity click detection with grid coordinate transform
- UIGrid: Check entities in reverse order, return sprite as target
Click events now correctly respect z-order (top elements get priority),
handle coordinate transforms for nested frames, and support clicking
on grid entities. Elements without click handlers are transparent to
clicks, allowing elements below to receive them.
Note: Click testing requires non-headless mode due to PyScene limitation.
feat: implement name system for finding UI elements (#39/40/41)
- Add 'name' property to UIDrawable base class
- All UI elements (Frame, Caption, Sprite, Grid, Entity) support .name
- Entity delegates name to its sprite member
- Add find(name, scene=None) function for exact match search
- Add findAll(pattern, scene=None) with wildcard support (* matches any sequence)
- Both functions search recursively through Frame children and Grid entities
- Comprehensive test coverage for all functionality
This provides a simple way to find UI elements by name in Python scripts,
supporting both exact matches and wildcard patterns.

Standardize sprite_index property and add scale_x/scale_y to UISprite
closes#81, closes#82
- Issue #81: Standardized property name to sprite_index across UISprite and UIEntity
- Added sprite_index as the primary property name
- Kept sprite_number as a deprecated alias for backward compatibility
- Updated repr() methods to use sprite_index
- Updated animation system to recognize both names
- Issue #82: Added scale_x and scale_y properties to UISprite
- Enables non-uniform scaling of sprites
- scale property still works for uniform scaling
- Both properties work with the animation system
All existing code using sprite_number continues to work due to backward compatibility.

Fix multiple low priority issues
closes#12, closes#80, closes#95, closes#96, closes#99
- Issue #12: Set tp_new to NULL for GridPoint and GridPointState to prevent instantiation from Python
- Issue #80: Renamed Caption.size to Caption.font_size for semantic clarity
- Issue #95: Fixed UICollection repr to show actual derived types instead of generic UIDrawable
- Issue #96: Added extend() method to UICollection for API consistency with UIEntityCollection
- Issue #99: Exposed read-only properties for Texture (sprite_width, sprite_height, sheet_width, sheet_height, sprite_count, source) and Font (family, source)
All issues have corresponding tests that verify the fixes work correctly.

Fix critical issues: script loading, entity types, and color properties
- Issue #37: Fix Windows scripts subdirectory not checked
- Updated executeScript() to use executable_path() from platform.h
- Scripts now load correctly when working directory differs from executable
- Issue #76: Fix UIEntityCollection returns wrong type
- Updated UIEntityCollectionIter::next() to check for stored Python object
- Derived Entity classes now preserve their type when retrieved from collections
- Issue #9: Recreate RenderTexture when resized (already fixed)
- Confirmed RenderTexture recreation already implemented in set_size() and set_float_member()
- Uses 1.5x padding and 4096 max size limit
- Issue #79: Fix Color r, g, b, a properties return None
- Implemented get_member() and set_member() in PyColor.cpp
- Color component properties now work correctly with proper validation
- Additional fix: Grid.at() method signature
- Changed from METH_O to METH_VARARGS to accept two arguments
All fixes include comprehensive tests to verify functionality.
