NAME

Term::Size::Any - Retrieve terminal size

SYNOPSIS

        # the traditional way
        use Term::Size::Any qw( chars pixels );

        ($columns, $rows) = chars *STDOUT{IO};
        ($x, $y) = pixels;

DESCRIPTION

This is a unified interface to retrieve terminal size. It loads one module of a list of known alternatives, each implementing some way to get the desired terminal information. This loaded module will actually do the job on behalf of `Term::Size::Any'.

Thus, `Term::Size::Any' depends on the availability of one of these

modules

        Term::Size           (soon to be supported)
        Term::Size::Perl
        Term::Size::ReadKey  (soon to be supported)
        Term::Size::Win32

This release fallbacks to Term::Size::Win32 if running in Windows 32 systems. For other platforms, it uses the first of Term::Size::Perl, Term::Size or Term::Size::ReadKey which loads successfully. (To be honest, I disabled the fallback to Term::Size and Term::Size::ReadKey which are buggy by now.)

FUNCTIONS

The traditional interface is by importing functions `chars' and `pixels' into the caller's space.

chars

            ($columns, $rows) = chars($h);
            $columns = chars($h);

        `chars' returns the terminal size in units of characters
        corresponding to the given filehandle `$h'. If the argument is
        ommitted, `*STDIN{IO}' is used. In scalar context, it returns the
        terminal width.

pixels

            ($x, $y) = pixels($h);
            $x = pixels($h);

        `pixels' returns the terminal size in units of pixels corresponding
        to the given filehandle `$h'. If the argument is ommitted,
        `*STDIN{IO}' is used. In scalar context, it returns the terminal
        width.

        Many systems with character-only terminals will return `(0, 0)'.
