Run lua --help for more options for the command line tool, and see the Lua Manual for extensive documentation of the Lua programming language and standard libraries. Also note LuaJIT's extensions

Installing Superpowers

You can use modules that implement more than the standard lua libraries by running the $ luarocks install >module name< command to download and install modules.

Lua4Win's luarocks configuration lives at [INSTALLDIR]/config/config-5.1.lua, and is a regular Lua file you can modify.

All of Lua4Win's binary packages are built using mingw64. If you intend to build your own modules they must be built with mingw64 if you want them to interoperate with Lua4Win-distributed Lua.

Some of Lua4Win's packages needed patching or modification, source code is generally mirrored at git.lua4.win, and packaging code is kept separate- usually in a *-packaging repo.
