# tainting(3pm)

(DEPRECATED) Enable taint mode lexically

## NAME

tainting - (DEPRECATED) Enable taint mode lexically

## VERSION

This document describes version 0.031 of tainting (from Perl distribution tainting), released on 2021-08-06.

## SYNOPSIS

To enable tainting in a lexical block:

```
 {
     use tainting;
     # tainting is enabled
 }
 # tainting is disabled again
```

To disable tainting in a lexical block:

```
 use tainting;
 {
     no tainting;
     # tainting is disabled
 }
 # tainting is enabled again
```

## DESCRIPTION

**DEPRECATION NOTICE**: tainting.pm is broken and will be purged from CPAN because the lexical switching is done at compile time while tainting is performed at runtime. Please see Taint::Runtime and localize `$TAINT` instead.

This module provides a simpler interface to Taint::Runtime. The idea is so that there is no functions or variables to import. Just `"use"` or `"no"`, like warnings or strict. Tainting of `%ENV` will be done one time automatically the first time this module is used.

Please (PLEASE) read Taint::Runtime's documentation first about the pro's and con's of enabling/disabling tainting at runtime. TL;DR: Use -T if you can.
