Luwra

A header-only C++ library which provides a Lua wrapper with minimal overhead.

Usage

Refer to the wiki pages or the documentation. In order to use the library you must clone this repository and add its lib/ folder to your include path.

Requirements

You need a C++14-compliant compiler and at least Lua 5.1 to get this library to work. I recommend using Lua 5.3 or later, to avoid the messy lua_Integer situation. LuaJIT 2.0 seems to work aswell.

Tests

The attached GNU Makefile allows you to run both examples and tests using make examples and make test respectively. You might need to adjust LUA_* variables, so Luwra finds the Lua headers and library.

Assuming all headers are located in /usr/include/lua5.3 and the shared object name is liblua5.3.so, you need to invoke this:

make LUA_INCDIR=/usr/include/lua5.3 LUA_LIBNAME=lua5.3 test

Assertions relying on lua_Integer will fail, due to integer quirks in Lua. This should only concern you if your application expects Lua integers to work like normal integers, because they don't. Since integers are internally stored as floating-point numbers before Lua 5.3, you might consider treating them as such in your application.
