Vl-remove-warnings

Remove warnings of certain types.

Signature

(vl-remove-warnings types x) → ans

Arguments

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

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

Returns

ans — Type (vl-warninglist-p ans).

This can be useful to filter out mundane warnings that you do not want to bother the user with.
