This is a Lua 5.1.5 port for ELKS.

Lua is built with OpenWatcom C for ELKS.

• Default ELKS build: make
• Optional Nano-X graphics backend: make USE_NANOX_BACKEND=1 NANOX_DIR=/path/to/microwindows/src

With the Nano-X backend enabled, the existing graphics helpers (vga_init, plot_pixel, plot_line, sleep_ms) run against a 320x200 Nano-X window instead of the raw VGA framebuffer. Existing scripts can still use vga_init(0x13) to open graphics mode and vga_init(3) to close it.

Branches are: https://github.com/rafael2k/lua/tree/lua-5.1 - Lua 5.1.5 with minimal patching to run on ELKS https://github.com/rafael2k/lua/tree/lua-5.1i - Special integer-only Lua 5.1.5 (does not have most mathlib functions) https://github.com/rafael2k/lua/tree/master - Tracking PUC-Rio upstream Lua (to become Lua 5.5), minimal patching for ELKS port
