Terminal Multi-Line Command Editor

Terminal Multi-Line Input with Edit, Insert, Delete, Print extension for IRIS
IRIS and Caché have just single command lines in terminal available
This Multi-Line Commands Editor also will execute the Multi-line Commands.
In addtiion, it is independent of access to %SYS and can be installed in any namespace

It is tested on IRIS/Caché Terminal , Putty, Linux Console, Docker Console,
Desktop Docker from Windows Command and WebTerminal.

This broad range of terminal emulations required navigation without any <ESC> sequences
as some of them are quite restrictive on input. So it got a little bit feeling like vi.

Installation with Docker

Prerequisites
Make sure you have git and Docker desktop installed.
Installation
Clone/git pull the repo into any local directory

$ git clone https://github.com/intersystems-community/objectscript-docker-template.git

Open the terminal in this directory and run:

After the first start you can trigger a system-wide installation in %SYS as %zme
in combinatin with a Command Extention ZME for simplified use (added to %ZLANGC00.mac)

At first run and if not a Command Extention just call it from terminal command prompt
