feat: Implement Sideline plugin system with consistent terminology
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.

Unified Pipeline Architecture.

Unified Pipeline Architecture (Compatibility Shim).
|
||||
|
||||
This module provides a clean, dependency-managed pipeline system:
|
||||
- Stage: Base class for all pipeline components
|
||||
- Pipeline: DAG-based execution orchestrator
|
||||
- PipelineParams: Runtime configuration for animation
|
||||
- PipelinePreset: Pre-configured pipeline configurations
|
||||
- StageRegistry: Unified registration for all stage types
|
||||
This module re-exports the pipeline architecture from Sideline for backward
|
||||
compatibility with existing Mainline code. New code should import directly
|
||||
from sideline.pipeline.
|
||||
|
||||
The pipeline architecture supports:
|
||||
- Sources: Data providers (headlines, poetry, pipeline viz)
|
||||
- Effects: Post-processors (noise, fade, glitch, hud)
|
||||
- Displays: Output backends (terminal, pygame, websocket)
|
||||
- Cameras: Viewport controllers (vertical, horizontal, omni)
|
||||
|
||||
Example:
|
||||
from engine.pipeline import Pipeline, PipelineConfig, StageRegistry
|
||||
|
||||
pipeline = Pipeline(PipelineConfig(source="headlines", display="terminal"))
|
||||
pipeline.add_stage("source", StageRegistry.create("source", "headlines"))
|
||||
pipeline.add_stage("display", StageRegistry.create("display", "terminal"))
|
||||
pipeline.build().initialize()
|
||||
|
||||
result = pipeline.execute(initial_data)
