sebastianbergmann/diff

This system is a PHP-based diff library that generates and formats text diffs using the Myers linear-space algorithm. It provides pluggable output builders for producing both loose and strict unified diff formats, alongside a robust exception hierarchy for error handling. The codebase is supported by modernized build automation, static analysis tooling, and comprehensive unit and integration tests.

This period focused on modernizing the project's build infrastructure by adopting Phive and Composer for dependency management, while simultaneously refactoring the core diff engine to use the Myers linear-space algorithm for improved performance. The changes included adding static analysis configurations, updating PHP version requirements, and introducing comprehensive unit tests for the new internal classes.

This period focused on enhancing code quality and reliability by upgrading the static analysis tooling from Psalm to PHPStan, introducing stricter type-checking rules, and expanding test coverage for exception handling, diff generation, and utility functions. The build system was also extended with a script to automate release note extraction from the changelog.
