Term::VT102::ZeroBased - Term::VT102 but with zero-based indices
use Term::VT102::ZeroBased; my $vt = Term::VT102::ZeroBased->new(cols => 80, rows => 24); $vt->process("\e[H"); # move to top left printf "(%d, %d)!\n", $vt->x, $vt->y; # (0, 0)!
Term::VT102, a module for terminal emulation, uses 1-based indices for screen positions. I find this annoying. So this is a simple wrapper around Term::VT102 that converts 1-based indices to 0-based indices.
Why, in particular, would you want this? Escape sequences use one-based indices, so it makes perfect sense for Term::VT102 to use one-based indices. But Curses uses zero-based indices. And so do most other modules.
See Term::VT102 for the documentation on using these modules.
