NAME

Term::Clear - `clear` the terminal via a perl function

VERSION

This document describes Term::Clear version 0.01

SYNOPSIS

    use Term::Clear ();

    Term::Clear::clear();

DESCRIPTION

Perl function to replace system("clear").

INTERFACE

clear()

Takes no arguments and clears the terminal screen in as portable way as possible.

Once it does all the work to determine the characters for the system the value is cached in memory so subsequent calls will be faster.

POSIX

By default it does not try to determine OSPEED from POSIX.

This is because some prefer to avoid loading POSIX for various reasons.

If you want it to try to do that you have two options:

load POSIX.pm before your first call to clear().
set $Term::Clear::POSIX to true before your first call to clear().
set $Term::Clear::POSIX to true via import():
    use Term::Clear 'POSIX';

DIAGNOSTICS

Throws no warnings or errors of its own.

CONFIGURATION AND ENVIRONMENT

Term::Clear requires no configuration files or environment variables.

DEPENDENCIES

It will use Term::Cap and POSIX::Termios if available.

INCOMPATIBILITIES AND LIMITATIONS

None reported.
