## Description

This package provides commands to send ANSI terminal control sequences to a terminal. All commands come in two variants, one for sending to any channel, the other for sending to stdout.

The commands are defined using the control sequences provided by the package term::ansi::code::ctrl. They have the same arguments as the commands they are based on, with the exception of the variant for sending to any channel. Their first argument is always a channel handle, then followed by the original arguments. Below we will list only the variant sending to stdout.

::term::ansi::send::import ?ns? ...

  Imports the commands of this package into the namespace ns. If not specified it defaults to send. Note that this default is a relative namespace name, i.e. the actual namespace will be created under the current namespace.

  By default all commands will be imported, this can however be restricted to specific commands, by listing them after the namespace to import them into.

::term::ansi::send::eeol

  Erase (to) End Of Line.

::term::ansi::send::esol

::term::ansi::send::scs0 tag
::term::ansi::send::scs1 tag

::term::ansi::send::cu ?n?

  Cursor Up. n defaults to 1.

::term::ansi::send::cd ?n?

  Cursor Down. n defaults to 1.

::term::ansi::send::cf ?n?

::term::ansi::send::cb ?n?

  Cursor Backward. n defaults to 1.

::term::ansi::send::ss ?s e?

::term::ansi::send::skd code str

  Set Key Definition.

::term::ansi::send::title str

  Set the terminal title.

::term::ansi::send::gron

  Switch to character/box graphics. I.e. switch to the alternate font.

::term::ansi::send::groff

  Switch to regular characters. I.e. switch to the default font.

::term::ansi::send::groptim str

  Optimize character graphics. The generator commands above create way to many superfluous commands shifting into and out of the graphics mode. This command removes all shifts which are not needed. To this end it also knows which characters will look the same in both modes, to handle strings created outside of this package.

::term::ansi::send::clear

  Clear screen. In essence a sequence of CursorHome + EraseDown.

::term::ansi::send::init

  Initialize default and alternate fonts to ASCII and box graphics.

::term::ansi::send::showat row col text

  Show the block of text at the specified location.
