Vl-elide-warnings

Cut down excessive warnings of certain types.

Signature

(vl-elide-warnings warnings cutoff) → new-warnings

Arguments

warnings — Warnings to filter.
    Guard (vl-warninglist-p warnings).

cutoff — Max warnings of each type to permit, or NIL for no eliding.
    Guard (maybe-natp cutoff).

Returns

new-warnings — Type (vl-warninglist-p new-warnings).
