unused-ignore (SMP009)

SMP009🛠️ Fix always availableCommentsAll rules

Reports selectors in # simplint: ignore[...] comments that no longer suppress a report under the active rule settings. Enable it with --extend-select SMP009 when checking for obsolete ignores.

Why is this bad?

An obsolete ignore makes it harder to tell which exceptions still matter. It can also hide a new report if the same rule starts applying to that line later.

Example

Flagged

value = 1  # simplint: ignore[single-letter-name]

Preferred

value = 1

What it does

The rule tests removals one selector at a time, then offers one safe fix for the file. It re-lints each proposed edit that might be unused and keeps the selector if removing it exposes any report, including one from a different rule. When a comment has several selectors, the fix keeps those that still suppress reports. A whole comment is removed when its last selector is unused.

The rule checks the rules currently selected for the file. If you run a narrow --select, selectors for rules outside that selection can appear unused. Use the project’s normal settings when cleaning up ignores.
