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 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)".

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.
