Which is the best Lua binding for C?
[nlua] – ‘namespace lua’ binding of C/C++ functions, table-like usage, templated based (no boost) [LuaWrapper] – A single header library that provides type-safe and intuitive functions such as luaW_to and luaW_push for arbitrary types, to make managing C++ classes with Lua simple.
What are the parameters of a function in Lua?
Following is the source code for a function called max (). This function takes two parameters num1 and num2 and returns the maximum between the two − If a function is to use arguments, it must declare the variables that accept the values of the arguments. These variables are called the formal parameters of the function.
How to write a C extension in Lua?
An [FFI] lets Lua code call C functions directly without having to write C “glue”, so you can use Alien to write C extensions purely in Lua. (Wraps libffi) [C/Invoke for Lua] (5.1) – Use [C/Invoke] from Lua to call C libraries (DLLs, .so files) directly, like Microsoft’s P/Invoke and Python’s ctypes.
Is there any sanity checking in Lua C?
By default, the Lua C API does almost no sanity checking of arguments passed to it. Passing incorrect stack indexes, for example, can result in segfaults or random data corruption. You should always enable API checking in any debug build.
Is there a way to compile C from Lua?
It allows compiling and loading C code directly from Lua, includes the ability to load C modules directly from C source. InlineCee provides a similar approach, invoking other compilers out-of-process. Various C++ or C++ template bindings have been developed to simplify the process in C++:
Can a Lua application be written in another language?
Lua can be embedded and extended [1] with code or applications written in other languages. Code and values in another language can be exposed to Lua and vice-versa. The following lists low and high level solutions for binding between Lua and other languages.
Which is an example of a Lua function?
For example, the sin function is defined as follows. luaL_check_number () is used to check the correct type of the sin function argument. lua_pushnumber () is used to return the sine calculated. Note, the return value of the math_sin () function is the number of values returned (lua functions can return many values).
