NAME

       DBIx::Class::Carp - Provides advanced Carp::Clan-like warning functions for DBIx::Class
       internals

DESCRIPTION

       Documentation is lacking on purpose - this an experiment not yet fit for mass consumption.
       If you use this do not count on any kind of stability, in fact don't even count on this
       module's continuing existence (it has been noindexed for a reason).

       In addition to the classic interface:

         use DBIx::Class::Carp '^DBIx::Class'

       this module also supports a class-data based way to specify the exclusion regex. A message
       is only carped from a callsite that matches neither the closed over string, nor the value
       of "_skip_namespace_frames" as declared on any callframe already skipped due to the same
       mechanism. This is to ensure that intermediate callsites can declare their own additional
       skip-namespaces.

CLASS ATTRIBUTES

   _skip_namespace_frames
       A classdata attribute holding the stringified regex matching callsites that should be
       skipped by the carp methods below. An empty string "q{}" is treated like no
       setting/"undef" (the distinction is necessary due to semantics of the class data accessors
       provided by Class::Accessor::Grouped)

EXPORTED FUNCTIONS

       This module export the following 3 functions. Only warning related "carp*" is being
       handled here, for "croak"-ing you must use "throw_exception" in DBIx::Class::Schema or
       DBIx::Class::Exception.

   carp
       Carps message with the file/line of the first callsite not matching
       "_skip_namespace_frames" nor the closed-over arguments to "use DBIx::Class::Carp".

   carp_unique
       Like "carp" but warns once for every distinct callsite (subject to the same ruleset as
       "carp").

   carp_once
       Like "carp" but warns only once for the life of the perl interpreter (regardless of
       callsite).
