Discover an effective approach to managing code quality in legacy projects through this 31-minute EuroPython 2022 conference talk. Learn about the "Clean as you code" philosophy, which focuses on measuring and improving the quality of recent changes rather than tackling the entire codebase at once. Explore techniques for dealing with legacy code, including using git diff with linters to target changed files. Understand the benefits of this approach, such as helping teams stay focused on delivering new features and addressing technical debt incrementally. Gain insights into implementing a quality gate to define code quality standards and learn about tools like SonarQube that can support this methodology.
