Bez explicitní konfigurace se výsledek lintů mění sám od sebe: výchozí sada pravidel ruffu se liší verzi od verze a flake8 hlásí generovaný resources.py, který se ručně neformátuje. Konfigurace je rozdělená schválně. amcr_viewer/.flake8 leží vedle metadata.txt, protože scanner na plugins.qgis.org hledá config soubory jen v kořeni balíčku uvnitř ZIPu; stejná pravidla tak platí v CI, lokálně i při uploadu. Konfigurace ruffu je v kořenovém pyproject.toml, ruff se do balíčku pluginu nedistribuuje. Ignorovaná pravidla mají v pyproject.toml odůvodnění: UP009 (hlavička utf-8 je konvence šablony Plugin Builderu), BLE001 (except Exception je záměr, výjimka nesmí propadnout do QGISu), SIM103 a SIM105 (čitelnost). Dvě opravy, které z konfigurace plynou: - open(path, 'r', encoding=...) -> open(path, encoding=...) [UP015] - zbytečné else: po return v get_komponenty() [RET505] Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WhQyc1uQFcpkezLwM8if6T
