Vl-keep-warnings

Keep only warnings of certain types.

Signature

(vl-keep-warnings types x) → ans

Arguments

types — Types of warnings to keep.
    Guard (symbol-listp types).

x — The list of warnings to filter.
    Guard (vl-warninglist-p x).

Returns

ans — Type (vl-warninglist-p ans), given (force (vl-warninglist-p x)).

This can be useful to highlight certain warnings that are of particular interest.
