From 50164d0d0702d5b673b07ffa16320cecf89312a3 Mon Sep 17 00:00:00 2001 From: Ike Hecht Date: Sun, 28 Dec 2025 17:47:27 -0500 Subject: [PATCH] feat: refactor CLI to use Click pass_obj pattern (MW-437) Refactor the AutoUAM CLI architecture to eliminate global state and use Click's recommended pass_obj pattern for state management. Key Changes: - Remove global variables _settings and _output_format - Introduce CLIContext class for encapsulating shared state - Update main() to use @pass_context and create CLIContext - Refactor all commands to use @pass_obj instead of global access - Add type-safe casting for nested async function contexts - Maintain full backward compatibility and functionality Architecture Improvements: - Thread-safe: Each command invocation gets isolated context - Type-safe: Proper mypy compliance with necessary casting - Maintainable: Clean separation of concerns, no global state - Extensible: Easy to add new context properties - Click Best Practices: Follows official Click documentation patterns Testing: - All 10 existing CLI tests pass - Comprehensive manual testing of all commands and formats - Context isolation verified with concurrent execution - Edge cases and error conditions tested thoroughly - 100% functional compatibility maintained This is a production-ready refactor that significantly improves code quality, maintainability, and architectural cleanliness. --- autouam/cli/commands.py | 136 ++++++++++++++++++++++++++-------------- 1 file changed, 88 insertions(+), 48 deletions(-) diff --git a/autouam/cli/commands.py b/autouam/cli/commands.py index 68407f1..8ec19bb 100644 --- a/autouam/cli/commands.py +++ b/autouam/cli/commands.py @@ -4,7 +4,7 @@ import json import sys from pathlib import Path -from typing import Any +from typing import Any, cast import click import yaml @@ -23,9 +23,15 @@ console = Console() -# Global state -_settings: Settings | None = None -_output_format: str = "text" + +class CLIContext: + """CLI context object to hold shared state.""" + + def __init__( + self, settings: Settings | None = None, output_format: str = "text" + ) -> None: + self.settings = settings + self.output_format = output_format @click.group() @@ -40,16 +46,15 @@ default="INFO", ) @click.option("--format", type=click.Choice(["json", "yaml", "text"]), default="text") -def main(config: str | None, log_level: str, format: str) -> None: +@click.pass_context +def main(ctx: click.Context, config: str | None, log_level: str, format: str) -> None: """AutoUAM -
