From #185 :

ruff format supports # fmt: off, # fmt: on and # fmt: skip pragma comments to selectively disable the formatter. (https://docs.astral.sh/ruff/formatter/#format-suppression)

It'd be neat if air supported a similar system for selective disabling formatting, which might look like this:

# fmt: off
private$event_callback_counts[[domain]] <- private$event_callback_counts[[domain]] - 1
# fmt: on

private$event_callback_counts[[domain]] <- private$event_callback_counts[[domain]] + 1 # fmt: skip

This came up previously in styler: r-lib/styler#365

Running air on the pkgdown source, tribbles (with an "r") are another case where the intentional formatting is important for readability, and these are clobbered by air.
