Term::Size::Any - Retrieve terminal size
# the traditional way
use Term::Size::Any qw( chars pixels );
($columns, $rows) = chars *STDOUT{IO};
($x, $y) = pixels;
This is a unified interface to retrieve terminal size. It loads one module of a list of known alternatives, each implementing some way to get the desired terminal information. This loaded module will actually do the job on behalf of Term::Size::Any.
Thus, Term::Size::Any depends on the availability of one of these modules:
Term::Size (soon to be supported)
Term::Size::Perl
Term::Size::ReadKey (soon to be supported)
Term::Size::Win32
This release fallbacks to Term::Size::Win32 if running in Windows 32 systems. For other platforms, it uses the first of Term::Size::Perl, Term::Size or Term::Size::ReadKey which loads successfully. (To be honest, I disabled the fallback to Term::Size and Term::Size::ReadKey which are buggy by now.)
The traditional interface is by importing functions chars and pixels into the caller's space.
($columns, $rows) = chars($h);
$columns = chars($h);
chars returns the terminal size in units of characters corresponding to the given filehandle $h. If the argument is omitted, *STDIN{IO} is used. In scalar context, it returns the terminal width.
($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 omitted, *STDIN{IO} is used. In scalar context, it returns the terminal width.
Many systems with character-only terminals will return (0, 0).
It all began with Term::Size by Tim Goodwin. You may want to have a look at:
Term::Size Term::Size::Perl Term::Size::Win32 Term::Size::ReadKey
