This is proof of concept of Lua running in Native Client. It is based on Lua 5.2.2. Changes in version 5.2.3.186: - hterm update (fixes cursor display issue) - Update to lua 5.2.3 Changes in version 5.2.2.1: - readline fixes - updated lua runtime from 5.1 to 5.2.

Pairs and ipairs are slightly different. Pairs returns key-value pairs and is mostly used for associative tables. Key order is unspecified. Ipairs returns index-value pairs and is mostly used for numeric tables. Non numeric keys in an array are ignored, while the index order is deterministic (in numeric order). The FFI library allows calling external C functions and using C data structures from pure Lua code. The FFI library largely obviates the need to write tedious manual Lua/C bindings in C. No need to learn a separate binding language — it parses plain C declarations! These can be cut-n-pasted from C header files or reference manuals. A Simple Example¶ Let’s create an extension module called spam (the favorite food of Monty. I am writing C functions for Lua. I have many calls like luagettable, luatouserdata, etc. My C function may receive complex structures like table with tables as fields. It is hard for me to program stacked machine. Is there way to write Lua script that would be converted to C code.

Lua C Extension Example

Lua BitOp is a C extension module for Lua 5.1/5.2which adds bitwise operations on numbers.

Features

Supported functions:bit.tobit, bit.tohex, bit.bnot, bit.band, bit.bor, bit.bxor,bit.lshift, bit.rshift, bit.arshift, bit.rol, bit.ror, bit.bswap
Consistent semanticsacross 16, 32 and 64 bit platforms.
Supports different lua_Number types:either IEEE 754 doubles, int32_t or int64_t.
Runs on Linux, *BSD, Mac OS X, Windows and probably anything elseyou can find.
Simple installation on all systems.No bulky configure scripts. Embedded-systems-friendly.
Internal self-test on startup to detect miscompiles.Includes a comprehensive test and benchmark suite.
Compatible with the built-in bitwise operations inLuaJIT 2.0.
It's as fast as you can get with the standard Lua/C API.
