NAME

Devel::Caller::Util - caller()-related utility routines

VERSION

This document describes version 0.042 of Devel::Caller::Util (from Perl distribution Devel-Caller-Util), released on 2019-04-12.

SYNOPSIS

 use Devel::Util::Caller qw(caller callers);

 my @info = caller(3);

 my @callers = callers();

FUNCTIONS

caller

Usage:

 caller([ $offset [, $with_args [, $packages_to_ignore [, $subroutines_to_ignore ] ] ] ]) => LIST

Just like the built-in caller(), except with three additional optional arguments. Will return this list:

     #  0          1           2       3             4          5            6           7             8        9          10
     ($package1, $filename1, $line1, $subroutine1, $hasargs1, $wantarray1, $evaltext1, $is_require1, $hints1, $bitmask1, $hinthash1)

If $with_args is true, will also return subroutine arguments in the 11th element of the result, produced by retrieving @DB::args.

$packages_to_ignore can be set to a regex (will be matched against $packageI) or an arrayref of package names.

Similarly, $subroutines_to_ignore can be set to a regex or an arrayref of subroutine names. Note that subroutine names are fully qualified names.

callers([ $start=0 [, $with_args [, $packages_to_ignore [, $subroutines_to_ignore ] ] ] ]) => LIST

A convenience function to return the whole callers stack, produced by calling caller() repeatedly from frame $start+1 until caller() returns empty. Result will be like:

 (
     #  0          1           2       3             4          5            6           7             8        9          10
     [$package1, $filename1, $line1, $subroutine1, $hasargs1, $wantarray1, $evaltext1, $is_require1, $hints1, $bitmask1, $hinthash1],
     [$package2, $filename2, $line2, ...],
     ...
 )

See "caller" for more information about the three additional, optional arguments.
