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 $h.
If the argument is omitted, *STDIN{IO} is used. In scalar context, it returns the terminal width.
pixels
($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 omitted, *STDIN{IO} is used. In scalar context, it returns the terminal width.
Many systems with character-only terminals will return "(0, 0)".
