.SH "NAME"
Term::Size::Any \- Retrieve terminal size
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 2
\&    # the traditional way
\&    use Term::Size::Any qw( chars pixels );
\&
\&    ($columns, $rows) = chars *STDOUT{IO};
\&    ($x, $y) = pixels;
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a unified interface to retrieve terminal size.
It loads one module of a list of known alternatives,
each implementing some way to get the desired terminal
information. This loaded module will actually do the job
on behalf of \f(CW\*(C`Term::Size::Any\*(C'\fR.
.PP
Thus, \f(CW\*(C`Term::Size::Any\*(C'\fR
depends on the availability of one of these modules:
.PP
.Vb 4
\&    Term::Size           (soon to be supported)
\&    Term::Size::Perl
\&    Term::Size::ReadKey  (soon to be supported)
\&    Term::Size::Win32
.Ve
.PP
This release fallbacks to Term::Size::Win32 if
running in Windows 32 systems. For other platforms,
it uses the first of
Term::Size::Perl, Term::Size or Term::Size::ReadKey
which loads successfully. (To be honest,
I disabled the fallback to Term::Size and Term::Size::ReadKey
which are buggy by now.)
.SS "\s-1FUNCTIONS\s0"
.IX Subsection "FUNCTIONS"
The traditional interface is by importing functions
\&\f(CW\*(C`chars\*(C'\fR and \f(CW\*(C`pixels\*(C'\fR into the caller's space.
.IP "\fBchars\fR" 4
.IX Item "chars"
.Vb 2
\&    ($columns, $rows) = chars($h);
\&    $columns = chars($h);
.Ve
.Sp
\&\f(CW\*(C`chars\*(C'\fR returns the terminal size in units of characters
corresponding to the given filehandle \f(CW$h\fR.
If the argument is omitted, \f(CW*STDIN{IO}\fR is used.
In scalar context, it returns the terminal width.
.IP "\fBpixels\fR" 4
.IX Item "pixels"
.Vb 2
\&    ($x, $y) = pixels($h);
\&    $x = pixels($h);
.Ve
.Sp
\&\f(CW\*(C`pixels\*(C'\fR returns the terminal size in units of pixels
corresponding to the given filehandle \f(CW$h\fR.
If the argument is omitted, \f(CW*STDIN{IO}\fR is used.
In scalar context, it returns the terminal width.
.Sp
Many systems with character-only terminals will return \f(CW\*(C`(0, 0)\*(C'\fR.
