Changes

• Allow to control terminal using Lua scripts via APC vt-sequences.

The built-in terminal is now capable of executing Lua scripts received via APC (Application Program Command) vt-sequences.

APC vt-sequence format:

ESC _ <script body> ESC \

or

ESC _ <script body> BEL

where:

• ESC_ is the APC vt-sequence prefix.
• <script body> - Lua script sent for execution.
• ESC\ or BEL - APC vt-sequence terminator.

Usage examples:

• bash:

  # Print the current scrollback buffer limits
  printf "\e_local n,m,q=vtm.terminal.ScrollbackSize(); vtm.terminal.PrintLn('size=', n, ' growstep=', m, ' maxsize=', q)\e\\"
  
  # Set the scrollback buffer limit to 10K lines
  printf "\e_vtm.terminal.ScrollbackSize(10000)\e\a"
  
  # Maximize the terminal window
  printf "\e_vtm.applet.Maximize()\e\\"
  

A complete list of available script functions can be found in settings.md.
