The Automation 4 Lua scripting engine is based on the version 5.1 series of the Lua scripting language.
This manual will not deal with the Lua language itself nor the standard libraries shipping with Lua, but only the additional functions and data structures provided by the Aegisub Automation 4 Lua interface. Please see the Lua 5.1 manual for details on the language itself and its standard libraries.
