BadImageFormatException when attempting to use LuaInterface
I imported LuaInterface into a console project, referenced it, and wrote a small test script. When i run it, i get this: Could not load file or assembly 'LuaInterface, Version=2.0.0.16708, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format. Forgive me for be...

Do file only once in Lua
Hi, I was wondering if there's a way to do a lua file only once and have any subsequent attempts to do that lua file will result in a no-op. I've already thought about doing something akin to C++ header's #if/else/endif trick. I'm wondering if there's a standard way to implement this. James ...
Lua: use table as args
Hi, I have numerous functions (unknown at design time) that each take a specific number of arguments. I have a table of arguments. How do I call those functions with this table of arguments? Thanks, James ...
Explanation of Asm code
Hi, The following GCC inline asm is taken from LuaJit's coco library. Can someone provide a line by line explanation of what it does? static inline void coco_switch(coco_ctx from, coco_ctx to) { __asm__ __volatile__ ( "movl $1f, (%0)\n\t" "movl %%esp, 4(%0)\n\t" "movl %%ebp, 8(%0)\n\t" "movl 8(%1), %%ebp\n\t" "...
Architecture for Qt application with Lua scripting - pause execution.
My embedded project contains a Qt application for the PC which is mainly a simulator for debugging and testing. In the application I can create several widgets which represent either my embedded software or simulate the hardware controlled by the application or can generate external inputs for testing. I plan to improve the application ...
Cloning Lua state
Folks, is there a way to clone a Lua state? In my game application the initialization procedure of the Lua virtual machine is pretty heavy(about 1 sec, since many scripts are loaded at once). I have a separate Lua VM for each autonomous agent and once the agent is created its Lua initialization affects FPS pretty badly. I'm thinking a...
What strategy should be used when exposing c++ to Lua
I have a c++ library which has functionality exposed to Lua, and am seeking opinions on the best ways to organise my lua code. The library is a game engine, with a component based Game Object system. I want to be able to write some of these components as classes in Lua. I am using LuaBind, so I can do this but there are some implementat...
Selecting random phrase from a list
Hi - I've been playing around with a .lua file which passes a random phrase using the following line: SendChatMessage(GetRandomArgument("text1", "text2", "text3", "text4"), "RAID") My problem is that I have a lot of phrases and the one line of code is very long indeed. Is there a way to hold text1 text2 text3 text3 in a list some...
Changing one table seems to change the other
I'm writing a lua script, and one of the things it does is copy a table into a table of tables, and apply a couple transformations to it. What's odd though is when i go to use one of those tables later (and modify some of it's properties), changes will also seem to show up in other tables! Code: -- thanks to http://stackoverflow.com/que...
Better way to architect this function?
I have a function that consists mainly of a massive amount of calls (50+) to another function which inserts data into an array, with logic here and there dictating various conditions to insert various items into the array (plus a little bit on the end that writes the contents of the array out to a file). I'm wondering if there isn't a be...
Concatenation of strings in Lua
In many languages you can concatenate strings on variable assignment. I have a scenario, using the Lua programming language, where I need to append the output of a command to an existing variable. Is there a functional equivalent in Lua to the below examples? Examples of other languages: ===== PERL ===== $filename = "checkbook"; $fil...
TCL vs Lua - scripting a mmo server
I have a c++ server side project that I need to embed some sort of scripting into. It is part of an online MMO type of server. I have significant experience using TCL, and it seems like the natural fit. I've done a minimal amount of Lua in my game dev days, and I wonder if this might be a better language for embedded scripting. It is als...
Concatenation of tables in Lua
ORIGINAL POST Given that there is no built in function in Lua, I am in search of a function that allows me to append tables together. I have googled quite a bit and have tried every solutions I stumbled across but none seem to work properly. The scenario goes like this: I am using Lua embeded in an application. An internal command of...

Reference to Lua function in C/C++

Lua: Get the literal name of the parameter
For example, function test (a) name = nameof(a) print(name) end test(def) --should print "def" Are there any lua tricks to implement something similar to the above? ...
Lua Closures in implementing a DSL
Lua has a really nice no-parenthesis call syntax that coupled with function closures allow me to write the following local tag = 1 function test(obj) return function(str) return function (tbl) tbl.objtag = tag tbl.objname = str return tbl end end end test (tag) "def" { } test tag ...
