      *For running & debugging of Lua script in VSC, with "Lua Debug":
        -Set the system environment variable "LUA_PATH = ./?.lua" in the SystemProperties, so that VSC finds required Lua scripts in the directory of this Lua script.
        -"os.exit()" in Lua scripts is not processed properly, by the will of the author of the plugin :-( => See below.
  *The Linter "luacheck" => See on this page.
  *".luacheckrc" => [[http://docs.coregames.com/extensions/#external-editors|Core Documentation "Core API / Editor Extensions"]]. Installation instructions: Extract the .luacheckrc file to your "C:\Users\<username>\Documents\My Games\Core\Saved\Maps" folder.
  *Proper setting in the VSC "settings.json" file:
    *Template:
      *"LuaCoderAssist.luacheck.execPath": "PATH TO FOLDER WITH luacheck.exe FILE".
      *"LuaCoderAssist.luaparse.luaversion": 5.3.
      *"LuaCoderAssist.luacheck.configFilePath": "PATH TO CORE MAPS FOLDER".
      *lua.luacheckPath": "PATH TO LUACHECK EXECUTABLE FILE TO BE CALLED ( e.g. 'luacheck.exe' or 'luacheck.bat' )".
=== Cross-development on Windows and Linux ( Visual Studio Code & Debugger & Luacheck & .luacheckrc ) ===
== .vscode ==
  *The directory ".vscode" is created in the working directory of VSC. It may contain "launch.json" and "tasks.json".
  *The reason for the VSC error message "You don´t have an extension for debugging Lua. Should we find a Lua extension in the Marketplace?" is mostly, that there is no "lauch.json" yet ( generated ).
  *My experience: If you change the debugger, or even change the script to be debugged, best is to start with frech "launch.json" file...
== Possible Attributes of "launch.json" ==
  *Comments in the VSC JSON file "launch.json" start with double slash ( "/ /", without space ).
  *Use IntelliSense to learn about possible attributes.
  *Hover to view descriptions of existing attributes.
  *For more information, visit: [[https://go.microsoft.com/fwlink/?linkid=830387|https://go.microsoft.com/fwlink/?linkid=830387]] ( [[http://code.visualstudio.com/docs/editor/debugging#_launch-configurations|VisualStudio Code "Documentation" - "Launch configurations"]] ).

    *Operation:
      *"To customize Run and Debug, create a launch.json file" => 3 JSON debugging configurations are created automatically: "Debug Lua Interpreter (Scripts)", "Debug Custom Lua Environement (Scripts)", "Debug Current File".
      *For successful step-by-step debugging ( "Start Debugging" ), you must set a RED breakpoint at the first non-comment line - both on VSC/Linux and VSC/Windows -. The Lua debugger halts, you may then move further step-by-step or run :-). Without a manual breaktpoint, the script is executed without debugging :-(.
      *OR you insert into your LUA script code, to start the LUA debugger manually:<code>
require("lldebugger").start()
</code>
    *The statement "os.exit()" is processed properly :-).
    *The statement "print(package.path)" prints the contents of the environment variable LUA_PATH, plus some more string contents :-) => See below.

    *Operation:
      *"To customize Run and Debug, create a launch.json file" => 2 JSON debugging configurations are created automatically: 
        *For Windows: "Debug (Scripts)", "Debug Current File".
        *For Linux: "Debug", "Debug Current File".
      *The statement "os.exit()" is not processed properly, both on Windows and Linux, by the will of the author of the plugin :-(.
        *[[http://www.github.com/actboy168/lua-debug/issues/139|GitHub "actboy168 / lua-debug", Issue "os.exit(0) is not processed properly #139"]].
        *Version 1.40.0 does not work properly in "Run Without Debugging" mode :-(: No debug console output :-(.
        *Version 1.40.0 works properly in "Start Debugging" mode, just if in the step mode. If :-(: If the button "Continue(F5)" is pressed, i.e. the debugger turns into "Run Without Debugging" mode, all debug console output is supressed :-(.
        *The software author suggests to use<code>
os.exit(0, true).
</code>
      *The statement "print(package.path)" doesn't print the contents of the environment variable LUA_PATH.
        *For the JSON debugging configuration "Debug (Scripts)", there is a fix => See below.
        *For the JSON debugging configuration "Debug Current File", the fix does not work.
      *On Debian Linux 10.7, LuaDebug 1.40.0 fails by the error message<code>

      *Suggestion to append some data to the environment settings for LuaRocks ( **of 2013, for Lua 5.2 on Win7 & Win8** ).
    *[[http://www.stackoverflow.com/questions/59155592/how-to-set-require-in-vscode-lua-settings-json|StackOverflow "How to set require in vscode Lua settings.json"]] - Suggestion to add a path to the Lua script variable "package.path" to name the location of Lua files created by LuaRocks when installing packages by LuaRocks.
    *My proper settings for Lua 5.3 on Win10:<code>
PATH =
C:\Program Files (x86)\LuaRocks;
LUA_PATH = 
./;
.\?\init.lua;
C:\Users\<user>\AppData\Roaming\luarocks\share\lua\5.3\?.lua;
C:\Users\<user>\AppData\Roaming\luarocks\share\lua\5.3\?\init.lua;
.\?.lua;
LUA_CPATH =
.\?.dll;C:\Users\<user>\AppData\Roaming\luarocks\lib\lua\5.3\?.dll
</code>
    *When running Lua Scripts by Powershell & CMD on Windows:
      *A Lua script executing "print(package.path)" prints the contents of the environment string variable "LUA_PATH" as stderr output on a Powershell or CMD console:<code>
./;.\?.lua;.\?\init.lua;C:\Users\Administrator\AppData\Roaming\luarocks\share\lua\5.3\?.lua;C:\Users\Administrator\AppData\Roaming\luarocks\share\lua\5.3\?\init.lua;
</code>
      *Executing Lua scripts with "require()" statements  works fine, both for local Lua modules and for Lua modules installed by LuaRocks.
   *When executing Lua Scripts in VisualStudio Code on Windows, by the VSC plugin "Local Lua Debugger":
      *A Lua script executing "print(package.path)" prints the contents of the environment string variable "LUA_PATH" and additional "c:\Users\Administrator\.vscode\extensions\tomblind.local-lua-debugger-vscode-0.2.1/debugger/?.lua" as output on the VSC Debug console:<code>
./;.\?.lua;.\?\init.lua;C:\Users\Administrator\AppData\Roaming\luarocks\share\lua\5.3\?.lua;C:\Users\Administrator\AppData\Roaming\luarocks\share\lua\5.3\?\init.lua;c:\Users\Administrator\.vscode\extensions\tomblind.local-lua-debugger-vscode-0.2.1/debugger/?.lua
</code>
   *When executing Lua Scripts in VisualStudio Code on Windows, by the VSC plugin "Lua Debug":
      *A Lua script executing "print(package.path)" prints as output on the VSC Debug console :-(, e.g.:<code>
C:\Users\<user>\WorkingDirectory/?.lua
</code>
      *A Lua script executed in VisualStudio Code on Windows, by the VSC plugin "Lua Debug", processes "require()" statements properly for local Lua modules not installed by LuaRocks.
      *A Lua script executed in VisualStudio Code on Windows, by the VSC plugin "Lua Debug", may process "require()" statements for Lua modules installed by LuaRocks, if the string contents of the environment variable "LUA_PATH" ( or relevant part of it ) are added to the global Lua variable "package.path":<code>
package.path = package.path .. ";C:\\Users\\<user>\\AppData\\Roaming\\luarocks\\share\\lua\\5.3\\?.lua;"
lu = require("luaunit")</code>
      *[[http://www.github.com/actboy168/lua-debug/issues/136|GitHub "actboy168 / lua-debug" Issue "print(package.path) != %LUA_PATH% ( 1.38.0 on Win10, 64bit ) #136"]] - Suggested workaround "Add path in launch.json, it can specify package.path".

        *So You may either add the missing LUA_PATH - this solution works both for Windows and Linux ! -:
          *By the VSC Extension Settings for "Lua Debug" ( recommended! )<code>
Lua > Debug > Settings: Path
Search path for Lua programs

${env:LUA_PATH}

    *Test files for LuaUnit: <code>
/usr/local/lib/luarocks/rocks/luaunit/3.4-1/test
</code>
    *LuaRocks as installed on Debian Linux 10.7 with Lua 5.3.3 by "sudo apt install luarocks", puts the important start script file for a Lua package ( e.g. "sudo luarocks install luaunit" => file "luaunit.lua" ) into a "5.1" directory, instead in a "5.3" directory :-(.<code>
/usr/local/share/lua/5.1
</code>

    *To fix that, either you have to created a "5.3" directory and copy the "5.1" data into it, or to set a soft link, so that the installed code is available for Lua5.3 users:<code>
cd /usr/local/share/lua
sudo ln -s ./5.1 ./5.3

cd /usr/local/lib/lua
sudo ln -s ./5.1 ./5.3
