Developed a global --no-format flag for the aleph-im/aleph-client repository, enabling users to disable rich formatting across all CLI commands for improved terminal readability and compatibility, especially on narrow screens. The implementation required deep integration with Python’s CLI development tools, ensuring that plain-text output propagated consistently through rich.console, rich.table, typer.style, colorful_json, and colorized_status. Addressed extensive linting and formatting issues using Black, Ruff, and MyPy, and refactored imports to stabilize test environments and prevent circular dependencies. Updated tests and fixtures to reflect the new output mode, enhancing CI reliability and reducing test flakiness while maintaining software quality.
