raku-terminal-size

Terminal::Size - raku programming language library to get a tty size Works on Linux, MacOS* and BSD*

Example using STDOUT

#!/usr/bin/raku
use Terminal::Size;

my winsize $size = terminal-size();
my uint16  $rows = $size.rows; # 76
my uint16  $cols = $size.cols; # 310

Example using custom IO::Handle

#!/usr/bin/raku
use Terminal::Size;

my $fd = "somefile.tty".IO.open: :r;

my $size = terminal-size($fd);

if !$size { # Failure
    note "Failed " ~ $size.exception.message;
    exit 1;
}

my uint16  $rows = $size.rows; # 76
my uint16  $cols = $size.cols; # 310

Exported symbols

• &terminal-size( IO::Handle:D $fd = $*OUT )
• struct winsize

Supported OS
