You may try perl. When it comes to regex and string parsing, perl handles them beautifully. Of course, doesn't mean you don't have other options.

dbix::class::carp
DBIx::Class::Carp(3pm) User Contributed Perl Documentation DBIx::Class::Carp(3pm)
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).
