Detailed Description

Main source directory (C++20, Lua).

Only a minimal amount of core source lives directly under this directory. Most code is placed under modules in each subdirectory (see the documentation of each of them for details). Dependencies between modules are kept to a minimum and with few exceptional cases the dependency graph is a DAG.

Configuration

All configuration is done using command-line arguments, and all command-line argument processing is done using Lua. Each argument is processed similarly to how the standalone Lua interpreter processes the LUA_INIT* variables:

• Each argument is executed in sequence.
• An argument with the format @filename causes filename to be read and executed as Lua code.
• Any other argument is executed literally as Lua code.
• Failure to execute any of the arguments aborts the initialization process. A failure exit code is returned.
