NAME

Term::Size::Perl - Perl extension for retrieving terminal size (Perl version)

SYNOPSIS

     use Term::Size::Perl;
 
     ($columns, $rows) = Term::Size::Perl::chars *STDOUT{IO};
     ($x, $y) = Term::Size::Perl::pixels;

DESCRIPTION

Yet another implementation of "Term::Size". Now in pure Perl, with the exception of a C probe run on build time.

FUNCTIONS

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)".

SEE ALSO

It all began with Term::Size by Tim Goodwin. You may want to have a look at: 
     Term::Size
     Term::Size::Unix
     Term::Size::Win32
     Term::Size::ReadKey

It would be helpful if you send me the Params.pm generated by the probe at build time. Please reports bugs via CPAN RT, http://rt.cpan.org/NoAuth/Bugs.html?Dist=Term-Size-Perl

BUGS

I am having some hard time to make tests run correctly under the "cpan" 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.

Update: This distribution uses new tests to skip if filehandle is not a tty. It was noticed that "Test::Harness" and "prove", for instance, provide a non-tty STDOUT to the test script and automatic installers could provide a non-tty STDIN. 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.
