Test::Vars(3) User Contributed Perl Documentation Test::Vars(3)NAMETest::Vars - Detects unused variables
VERSION
This document describes Test::Vars version 0.001.
SYNOPSIS
use Test::Vars;
all_vars_ok(); # check libs in MANIFEST
DESCRIPTIONTest::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 opcodes (or AST:
abstract syntax tree) using the "B" module. See also "B" and its
submodules.
DEPENDENCIES
Perl 5.10.0 or later.
BUGS
All complex software has bugs lurking in it, and this module is no
exception. If you find a bug please either email me, or add the bug to
cpan-RT.
