DerelictLua by Michael Weber, Jr. This project is bindings to the Lua programming language (www.lua.org) using the Derelict2 project (www.dsource.org/projects/derelict). This project only supports Lua 5.2 and a D2 compiler. Currently this project only targets windows. If someone comes up with code for other operating systems, I will be glad to include it. To build on windows using the build.bat you must check out DerelictLua into the same folder as your Derelict2 location. The DerelictLua folder should be in the same directory as DerelictUtil, DerelictGL, etc... Otherwise you need to edit the build.bat file to reflect your directory setup. By default it will create DerelictLua.lib in the \lib folder and it will create interface files in the \import folder. DerelictLua comes with four import files: derelict\lua\lua.d : Imports luatypes.d and luafuncs.d and defines the DerelictLua import object derelict\lua\luatypes.d : Various enums and aliases to the Lua types derelict\lua\luafuncs.d : The Lua functions derelict\lua\luad.d : Templetes to common Lua functions for D WARNING: In building DerelictLua I found that compiling with -O caused some very bad things to happen that I think are caused by a compiler error but I am looking into. For the mean time do not compile DerelictLua or any code that links to it with -O. derelict\lua\luad.d must imported on its own and needs some explaining. The other bindings in Derelict do very little to clean up the interface between C and D by design. For this project I felt that Lua has a number functions that all do the same basic thing but for different types and would benefit from the ability to group them into one function to call. In that light luad.d defines the following functions: These functions all evalutate their parameters at compile time bool lua_is(T)(lua_State*, int) This function overloads the lua_is*(lua_State*, int) functions. e.g. lua_is!lua_Number(lua_state, -1); // checks the top of the stack to see if it is a lua_Number T lua_to(T)(lua_State*, int) This function overloads the lua_to*(lua_State*, int) functions. e.g. auto x = lua_to!int(lua_state, -1); // returns the top of the stack as an int void lua_push(T)(lua_State*, T) This function overloads the lua_push*(lua_State*, int) functions. e.g. lua_push!int(lua_state, 20); Only lua_tostring is supporeted from the string facilities as lua_push!string Some of the push functions return pointers to the data, this function discards them void lua_push(T)(lua_State*) Overload of the previous function for lua_pushthread and lua_pushnil void lua_push(T)(lua_State*, T, int) Overload of the previous function for lua_pushcclosure In order to support the above functions, luad.d defines the following aliases: alias lua_State* lua_Thread; // Note that this is already a pointer type and that "lua_Thread* thread" is wrong alias void* lua_Function; alias void* lua_Table; alias void* lua_Userdata; alias void* lua_LightUserdata; alias void lua_Nil; I am pretty sure everything works but I have not tested it throughly, please let me know of any bugs that you discover. But while we are on that subject, luaL_loadfile does not work for me and I have not found out why. A workaround is to load the file in D, build a string and use luaL_dostring instead.
