Test::Vars - Detects unused variables
This document describes Test::Vars version 0.005.
use Test::Vars; all_vars_ok(); # check libs in MANIFEST
Test::Vars finds unused variables in order to keep the source code tidy.
Tests libraries in your distribution with %args.
libraries are collected from the MANIFEST file.
If you want to ignore variables, for example $foo, you can tell it to the test routines:
$foo
ignore_vars => { '$foo' => 1 }
ignore_vars => [qw($foo)]
ignore_if => sub{ $_ eq '$foo' }
Note that $self will be ignored by default unless you pass explicitly { '$self' => 0 } to ignore_vars.
$self
{ '$self' => 0 }
ignore_vars
Tests $lib with %args.
See all_vars_ok.

Test::Vars is similar to a part of Test::Perl::Critic,but the mechanism is different.

Test::Perl::Critic
While Perl::Critic, the backend of Test::Perl::Critic, scans the source code as texts, this modules scans the compiled opcode (or AST: abstract syntax tree) using the B module. See also B and its submodules.
