The old engine/pipeline/core.py file was removed as part of the Sideline/Mainline split.
All imports that referenced engine.pipeline.core have been updated to use engine.pipeline
which re-exports from sideline.pipeline.core.
This ensures consistency and avoids duplicate DataType enum instances.
This commit implements the Sideline/Mainline split with a clean plugin architecture:
## Core Changes
### Sideline Framework (New Directory)
- Created directory containing the reusable pipeline framework
- Moved pipeline core, controllers, adapters, and registry to
- Moved display system to
- Moved effects system to
- Created plugin system with security and compatibility management in
- Created preset pack system with ASCII art encoding in
- Added default font (Corptic) to
- Added terminal ANSI constants to
### Mainline Application (Updated)
- Created for Mainline stage component registration
- Updated to register Mainline stages at startup
- Updated as a compatibility shim re-exporting from sideline
### Terminology Consistency
- : Base class for all pipeline components (sources, effects, displays, cameras)
- : Base class for distributable plugin packages (was )
- : Base class for visual effects (was )
- Backward compatibility aliases maintained for existing code
## Key Features
- Plugin discovery via entry points and explicit registration
- Security permissions system for plugins
- Compatibility management with semantic version constraints
- Preset pack system for distributable configurations
- Default font bundled with Sideline (Corptic.otf)
## Testing
- Updated tests to register Mainline stages before discovery
- All StageRegistry tests passing
Note: This is a major refactoring that separates the framework (Sideline) from the application (Mainline), enabling Sideline to be used by other applications.
