execution_registry.py
This module provides the `ExecutionRegistry`, a global class for tracking and
introspecting the execution history of Falyx actions.
The registry captures `ExecutionContext` instances from all executed actions, making it
easy to debug, audit, and visualize workflow behavior over time. It supports retrieval,
filtering, clearing, and formatted summary display.
Core Features:
- Stores all action execution contexts globally (with access by name).
- Provides live execution summaries in a rich table format.
- Enables creation of a built-in Falyx Action to print history on demand.
- Integrates with Falyx's introspectable and hook-driven execution model.
Intended for:
- Debugging and diagnostics
- Post-run inspection of CLI workflows
- Interactive tools built with Falyx
Example:
from falyx.execution_registry import ExecutionRegistry as er
er.record(context)
er.summary()

class ExecutionRegistry:
"""
Global registry for recording and inspecting Falyx action executions.
This class captures every `ExecutionContext` generated by a Falyx `Action`,
`ChainedAction`, or `ActionGroup`, maintaining both full history and
name-indexed access for filtered analysis.
Methods:
- record(context): Stores an ExecutionContext, logging a summary line.
- get_all(): Returns the list of all recorded executions.
- get_by_name(name): Returns all executions with the given action name.
- get_latest(): Returns the most recent execution.
- clear(): Wipes the registry for a fresh run.
- summary(): Renders a formatted Rich table of all execution results.
Use Cases:
- Debugging chained or factory-generated workflows
- Viewing results and exceptions from multiple runs
- Embedding a diagnostic command into your CLI for user support
Note:
This registry is in-memory and not persistent. It's reset each time the process
restarts or `clear()` is called.
Example:
ExecutionRegistry.record(context)
ExecutionRegistry.summary()
