Terminal::Width - Get the current width of the terminal
use Terminal::Width;
# Default to 80 characters if we fail to get actual width:
my $width = terminal-width;
# Default to 100 characters if we fail to get actual width:
$width = terminal-width :default<100>;
# return a Failure if we fail to get actual width:
$width = terminal-width :default<0>;This module tries to figure out the current width of the terminal the program is running in. The module is known to work on Windows 10 command prompt and Debian flavours of Linux as well as MacOS.
terminal-width (Int :$default = 80 --> Int|Failure)Returns and Int representing the character width of the terminal. Takes one optional named argument default that specifies the width to use if we fail to determine the actual width (defaults to 80). If :default is set to 0 the subroutine will return a Failure if it can't determine the width.
On Windows, this module attempts to run program mode and on all other systems it attempts to run tput. A clever attacker can manipulate what the actual executed program is, resulting in it being executed with the privileges of your script's user.
