Module Version: 0.005   Source  

NAME ^

Test::Vars - Detects unused variables

VERSION ^

This document describes Test::Vars version 0.005.

SYNOPSIS ^

    use Test::Vars;

    all_vars_ok(); # check libs in MANIFEST

DESCRIPTION ^

Test::Vars finds unused variables in order to keep the source code tidy.

INTERFACE ^

Exported

all_vars_ok(%args)

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:

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.

vars_ok($lib, %args)

Tests $lib with %args.

See all_vars_ok.

MECHANISM ^

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

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.

CONFIGURATION ^

TEST_VERBOSE = 1 | 2 shows the way this module works.
