Lua Do String Cho
Lua Custom Loadstring

Lua.doString (`function f. Dump this function as a binary chunk of Lua bytecode to the specified writer delegate. Multiple chunks may be produced to dump a single. The value is left on the Lua stack. In order to retrieve the value, use one of the luatoXXXX functions, with -1 as the index argument (-1 refers to the top of the stack). Alternatively, use luagettop to get the size of the stack. In your case, use this: luaLdostring (L, 'return 'somestring'); const char. str = luatostring (L, -1); Share. In order to access it from C, we could hack a little program that would construct the table, pass it to the script, and get the returned value. Create a C program called 'test.c' as follows: /. test.c. Example of a C program that interfaces with Lua. Based on Lua 5.0 code by Pedro Martelletto in November, 2003. Updated to Lua 5.1. A C function called from Lua is a block, and its parameters are valid only until its end. It is good programming practice to convert Lua objects to C values as soon as they are available, and never to store luaObjects in C global variables. A garbage collection cycle can be forced by: long lua. LuaD is a bridge between the D and Lua programming languages. Unlike many other libraries built on the Lua C API, LuaD doesn't expose the Lua stack - instead, it has wrappers for references to Lua objects, and supports seamlessly and directly converting any D type into a Lua type and vice versa.
