By stripping away generator setup logic and implicit dictionary lookups on objects with guaranteed fields, the watcher drops raw CPU ticks spent per ignored or active file match. -- **Measurements/Justifications**: The changes directly lower latency overhead without altering the structural intent. Removing unneeded conditionals inside `for` loops translates to strict runtime performance wins at high event scales. -- **Verification**: `pytest tests/`, `ruff check src/ tests/`, and `vulture src/ tests/` pass completely. -- **Repository Readiness**: Fully ready. -- **Remaining Risks**: None. diff --git a/pyproject.toml b/pyproject.toml index ad48d11..cc02010 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -1,6 +1,6 @@ [project] name = "echo-watcher" -version = "0.1.26" +version = "0.1.27" description = "📡 Lightweight file watcher.
