NAME ^

Term::Size::ReadKey - Retrieve terminal size (via Term::ReadKey)

SYNOPSIS ^

    use Term::Size::ReadKey;

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

DESCRIPTION ^

Yet another implementation of Term::Size. Now using Term::ReadKey to do the hard work.

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).

BUGS ^

The basic test may fail harshly when running under the test harness. This happens with Term::ReadKey alone as well. Term::ReadKey gets away with murder by setting COLUMNS and LINES environment variables (which are used as a fallback). This release also applies the same cheat. I gotta find a more decent fix to these issues.
