Contributions summary:Leiser primarily contributed to the Ruff linter and code formatter, focusing on implementing and improving code analysis rules. They implemented new rules related to internationalization, including checks for f-strings, format methods, and printf-style formatting within i18n calls. The user also added autofix functionality to remove try-except-pass blocks with contextlib.suppress, and extended an existing rule for ellipsis-only exception handlers. Furthermore, they fixed a potential panic during an out-of-bounds edit operation and made ruff format idempotent when using stdin input.
