NAME

Devel::MAT::Tool::Identify - identify an SV by its ancestry

DESCRIPTION

This Devel::MAT tool provides a command to identify an SV by walking up its tree of inrefs, printing useful information that helps to identify what it is by how it can be reached from well-known program roots.

COMMANDS

identify

pmat> identify 0x1bbf640
IO() at 0x1bbf640 is:
└─the io of GLOB(@*I) at 0x1bbf628, which is:
  └─the ARGV GV

Prints a tree of the identification of the SV at the given address.

Takes the following named options:

--depth D, -d D

Limits the output to the given number of steps away from the given initial SV.

--weak

Include weak direct references in the output (by default only strong direct ones will be included).

--all

Include both weak and indirect references in the output.

--no-elide, -n

Don't elide REF()-type SVs from the output. By default these will be skipped over, leading to a shorter neater output by removing this usually-unnecessary noise.

If this option is not given, elided reference SVs will be notated by adding (via RV) to the reference description.
