NAME

Term::VT102::Incremental - get VT updates in increments

VERSION

version 0.05

SYNOPSIS

  my $vti = Term::VT102::Incremental->new(
    rows => 50,
    cols => 100,
  );

  $vti->process(...);
  my $updates = $vti->get_increment(); # at time X

  $vti->process(...);
  $vti->process(...);
  my $updates_since_time_X = $vti->get_increment(); # at time Y

DESCRIPTION

Term::VT102::Incremental is a thin wrapper around Term::VT102 with a few internal differences. This module takes the exact same arguments in the constructor as Term::VT102, but has one extra method: get_increment.

ATTRIBUTES

vt

Intermal Term::VT102 object. You can make any configurations that any other normal Term::VT102 object would let you make.

METHODS

process

See Term::VT102's process.

rows

See Term::VT102's rows.

cols

See Term::VT102's cols.

vt_class

Returns the name of the VT class that the internal VT object will use when instantiated. Currently defaults too Term::VT102 but can be overridden by extending this class.

get_increment

After one or more updates, you can call get_increment to see the incremental series of updates you've made. It returns an arrayref of 3-element lists: row, cell, and cell property differences.

Cell properties consist of:

Foreground (fg)
Background (bg)
Boldness (bo)
Faint (fa)
Standout (st)
Underline (ul)
Reverse coloring (rv)

See the attr_pack method in the Term::VT102 documentation for details on this.
