.SH "NAME"
Term::Size::Perl \- Perl extension for retrieving terminal size (Perl version)
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&    use Term::Size::Perl;
\&
\&    ($columns, $rows) = Term::Size::Perl::chars *STDOUT{IO};
\&    ($x, $y) = Term::Size::Perl::pixels;
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Yet another implementation of \f(CW\*(C`Term::Size\*(C'\fR. Now
in pure Perl, with the exception of a C probe run
on build time.
.SS "\s-1FUNCTIONS\s0"
.IX Subsection "FUNCTIONS"
.IP "\fBchars\fR" 4
.IX Item "chars"
.Vb 2
\&    ($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.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
It all began with Term::Size by Tim Goodwin. You may want to
have a look at:
.PP
.Vb 4
\&    Term::Size
\&    Term::Size::Unix
\&    Term::Size::Win32
\&    Term::Size::ReadKey

.PP
It would be helpful if you send me the \fIParams.pm\fR generated by
the probe at build time.

.SH "BUGS"
.IX Header "BUGS"
I am having some hard time to make tests run correctly
under the \f(CW\*(C`cpan\*(C'\fR script. Some Unix systems do not seem to provide a
working tty inside automatic installers. I think it needs
some skip tests, but I am yet not sure what should be the
portable tests for this.
.PP
Update:
This distribution uses new tests to skip if filehandle
is not a tty. It was noticed that \f(CW\*(C`Test::Harness\*(C'\fR and
\&\f(CW\*(C`prove\*(C'\fR, for instance, provide a non-tty \s-1STDOUT \s0
to the test script and automatic installers
could provide a non-tty \s-1STDIN.\s0 So the former tests 
were basically wrong. I am improving my understanding
of the involved issues and I hope to soon fix the
tests for all of Term::Size modules.
