Over the past couple of commits, the build process now automates the
dependenices you'd normally compile from source.
This commit is focused on laying the foundation for scriptable in-game
commands using Lua.
- sol2 and lua5.4 are the new project dependencies.
- Created a new 'LuaProcessor' class to manage a Lua state and eecute
scripts.
- The 'CommandProcessor' now contains a 'LuaProcessor' instance.
- Replaced the hardcoded c++ 'ls' command with a system that executes a
'/bin/ls.lua' script from the Virtual File System.
- Implemented C++ -> Lua bindings for the 'vfs_node' struct, allowing
Lua scripts to inspect the VFS and perform actions (i.e, list files).
This is the beginning of the remote session functionality. It allows
players to connect to different NPC systems via an 'ssh' command.
*Server*
- Can now manage a world of multiple NPC file systems that are
identified by IP addresses.
- Implemented SSH command to allow connection to remote NPC systems.
Each remote session is managed via a 'CommandProcessor'.
- 'exit' command causes the remote server to terminate the client
connection
*Client*
- Terminal can enter a 'remote' state via the SSH command which sends
subsequent commands to the server.
- the local 'exit' command will close the terminal window.
- Refactored UI object ownership to prevent memory leaks and ensure
proper cleanup when a window is closed or the terminal application.
