I have 3 lua files, Init.lua, FreeCamera.lua and Camera.lua , init.lua calls require "Core.Camera.FreeCamera" Free Camera: module(...) require "Core.Camera.Camera" local M = {} FreeCamera = M M = Class( Camera ) function M:__constructor(x,y,z) self.Active = false self.x = x self.y = y self.z = z end and module(...) lo...
I'm using Electro in Lua for some 3D simulations, and I'm running in to something of a mathematical/algorithmic/physics snag. I'm trying to figure out how I would find the "spin" of a sphere of a sphere that is spinning on some axis. By "spin" I mean a vector along the axis that the sphere is spinning on with a magnitude relative to the...
Hi, I've hit s small block with string parsing. I have a string like: footage/down/temp/cars_[100]upper/cars[100]_upper.exr and I'm having difficulty using gsub to delete a portion of the string. Normally I would do this lineA = footage/down/temp/cars_[100]_upper/cars_[100]_upper.exr lineB = footage/down/temp/cars_[100]_upper/ ne...
I have a lua table that I use as a hashmap, ie with string keys : local map = { foo = 1, bar = 2 } I would like to "pop" an element of this table identified by its key. There is a table.remove() method, but it only takes the index of the element to remove (ie a number) and not a generic key. I would like to be able to do table.remove(...
I am having trouble getting embedded wxLua to work with my application -- it works fine when I use the wxLua DLLs, but I'm trying to use the static libraries so I can distribute a single, standalone executable with no external dependencies. First, the symptoms: Most controls (such as wxButtons, wxGauges, wxTextCtrls) do not display; at ...
I have a C function that takes FILE* as an argument and I'd like to use this function in Lua, passing Lua file. I guess I need a %typemap for this. How to write it? (I just started learning Lua). ...
I am using a 3D engine called Electro which is programmed using Lua. It's not a very good 3D engine, but I don't have any choice in the matter. Anyway, I'm trying to take a flat quadrilateral and transform it to be in a specific location and orientation. I know exactly where it is supposed to go (i.e. I know the exact vertices where the...
Hi, I'm exploiting the behavior of the constructors of C++ global variables to run code at startup in a simple manner. It's a very easy concept but a little difficult to explain so let me just paste the code: struct _LuaVariableRegistration { template<class T> _LuaVariableRegistration(const char* lua_name, const T& c_name) { ...
Hi, I have some lua script that have some long running task like getting a web page so I make it yield then the C code handle get page job async, so the thread free to do other job and after a specify time it check back to see is the get page job finished , if so then resume the script. the problem is the thread can't resume the job afte...
Would it be possible using Lua and SWIG and say an IInterface class, to implement that interface and instantiate it all within Lua? If so how would it be done? ...
I am writing a Lua script that works with IMAPfilter (http://imapfilter.hellug.gr/), that is able to change the names of MIME attachments for example: Content-Type: application/pdf; name="Final Fäntäsy.pdf" is converted to Content-Type: application/pdf; name="FinalFantasy.pdf" Currently, this is done via exporting the mail to the...
I want to use lua (that internally uses only doubles) to represent a integer that can't have rounding errors between 0 and 2^64-1 or terrible things will happen. Is it possible to do so? ...
Is it possible in lua to execute a function from a string representing its name? i.e: I have the string x = "foo", is it possible to do x() ? If yes what is the syntax ? ...
Currently I know how to have C++ objects instantiated and passed around in Lua using SWIG bindings, what I need is the reverse. I am using Lua & C++ & SWIG. I have interfaces in C++ and objects in lua, that implement methods which do the same job and have the same structure. I would like to be able to instantiate these objects in lua y...
This may seem like a stupid question, but what are the symbols used for string replacement in string.format? can someone point me to a simple example of how to use it? ...
In my lua program, i want to stop and ask user for confirmation before proceeding with an operation. I'm not sure how to stop and wait for user input, how can it be done? ...
I have a process object setup like the following: Process p = new Process(); p.StartInfo.FileName = command; p.StartInfo.UseShellExecute = true; p.StartInfo.Arguments = String.Format( commandArguments, destinationLocation, sourceLocation, sourceDirName, (string.IsNullOrEmpty(revisionNotes.Text)) ? "" : revisionNotes....
I want to work with a modem interfaced on a serial port on an embedded platform. Here are some solutions I have rejected so far : Expect plus a terminal program : My (cross)build system does not have any package rules for expect, and according to the installation instructions from the expect sources, the configure script needs to be i...
For example: items = { [753] = { }, [192] = { }, [789] = { }, [791] = { }, [790] = { }, [776] = { }, } I would like to remove 789 and all data inside of it. I tried both: table.remove( items, 2 ); and table.remove( items, 789 ); ( I wasn't sure how the indexing worked ) with no luck. T...
Does anyone know if Lua has been certified to run on an airframe or road vehicle? Certification processes such as DO178B (RTCA) or standardization such as ISO 26262 (Road vehicles). Certification is like case law and I would feel more confident evaluating the language knowing that another company has successfully made it through a proce...
