Description

::

logtalk_linter_hook(Goal, Flag, File, Lines, Type, Entity, Warning)

Multifile user-defined predicate, supporting the definition of custom linter warnings. Experimental. The Goal argument can be a message sending goal, Object::Message, a call to a Prolog built-in predicate, or a call to a module predicate, Module:Predicate. The Flag argument must be a supported linter flag. The Warning argument must be a valid core message term. For a given Goal, only the first successful call to this predicate is considered.

Modes and number of proofs
