• Setting timeout for embedded Lua

  - by skyeagle

  I have embedded Lua in a C/C+= application. I want to be able to set a timeout value to prevent getting trapped with badly written scripts that can result in infinite loops (or even string searches that take an infinite time to complete). Basically, I want to be able to set a time interval and if the script fails to complete running at the end of…

  I have embedded Lua in an Objective-C application using LuaObjCBridge. I need to know how to stop the Lua process if it taking too much time (infinite loop?). Would running it in a separate thread help?

• current line number in Lua

  - by prideout

  Does Lua support something like C's _LINE_ macro, which returns the number of the current code line? I know Lua has a special built-in variable called _G, but I don't see line number in there...

• lua metatable __lt __le __eq forced boolean conversion of return value

  - by chris g.

  Overloading __eq, __lt, and __le in a metatable always converts the returning value to a boolean. Is there a way to access the actual return value? This would be used in the following little lua script to create an expression tree for an argument usage: print(_.a + _.b - _.c * _.d + _.a) -> prints "(((a+b)-(c*d))+a)" which is…

• Footprint of Lua on a PPC Micro

  - by Adam Shiemke

  We're developing some code on Freescale PPC micros (5517 and 5668 at the moment), and I was wondering if we could put Lua on them. The devices need to be easily programmed/reconfigured in the field, and the current product uses a proprietary interpreted logic language that can be loaded in, and our software (written in C) runs an interpreter.…

• Launching Vim via Lua

  - by Keith Pimmel

  I'm writing a simple little Lua commandline app that will build a static website. I'm storing my fragments in a sqlite database. Retrieving the data from the db is straightforward as is saving it; my question comes from editing the data. Is there an elegant way to pipe the data from Lua to vim? Can vim edit a memory buffer and return it? I…

• using sqlite3 with lua

  - by mr calendar

  I'm trying to use sqlite3 with lua (am already using c++, but I'm a n00b with lua- I read this) but I'm getting the following when trying to build the library or whatever: C:\lib\lsqlite3-7>mingw32-make process_begin: CreateProcess(NULL, pkg-config --version, ...) failed. makefile:53: *** windows32. Stop. I'm not at all surprised at…

• Node.js for lua?

  - by Shahbaz

  I've been playing around with node.js (nodejs) for the past few day and it is fantastic. As far as I can tell, lua doesn't have a similar integration of libev and libio which let's one avoid almost any blocking calls and interact with the network and the filesystem in an asynchronous manner. I'm slowly porting my java implementation to…

• lua string printing

  - by anon

  In C, I have format strings, something like: char *msg = "wlll you marry me" fprintf(stderr, "%s, %s?", name, msg); Now, can I do something similar in lua with format strings? I.e. I want something functionally equivalent to: name .. ", " .. msg .. "?" but not so ugly, in lua. Okay, so I can do string.format("%s, %s?", name,…

• quasiquote/quote in lua?

• Convert hex to decimal keeping fractional part in Lua

  - by Zack Mulgrew

  Lua's tonumber function is nice but can only convert unsigned integers unless they are base 10. I have a situation where I have numbers like 01.4C that I would like to convert to decimal. I have a crummy solution: function split(str, pat) local t = {} local fpat = "(.-)" .. pat local last_end = 1 local s, e,…

• LuaJit FFI and hiding C implementation details

  - by wirrbel

  I would like to extend an application using LuaJit FFI. Having seen http://luajit.org/ext_ffi_tutorial.html this is surprisingly easy when comparing this to the Lua C API. So far so good. However I do not plainly want to wrap C functions but provide a higher level API to users writing scripts for the application.…

• Execute remote Lua Script

  - by Bruno Lee

  Hi, I want to make an application that executes a remote script. The user can create a script (probabily a LUA script) then stores it in the server. Then he can uses an API for execute the script. I was thinking that API could be a webservice. So my questions are: I need high performance to execute the script.…

• Nested luabind classes declared in Lua

  - by Matt Fichman

  I am trying to declare a class B in a namespace A using Luabind (from the Lua side). I figure that if Luabind has a clean way to do this, it would look something like this: class 'A.B' (Super) function A.B:__init() Super.__init(self) end Notice that the B class is defined in the A table. I know the…

• lua recursive repl on error?

  - by anon

  In many scheme/lisp dialects, when an error occurs, a "recursive repl" is popped up ... one can execute scheme/lisp code at the frame where the error occured, and go up/down the stack. Is it possible to do something similar to this in lua? Thanks!

• Lua + SWIG Monkey Patching

  - by Tom J Nowell

  I have used SWIG to bind a set of classes to lua. The problem comes if I want to start monkey patching. e.g. game.GetEnemies1 = game.GetEnemies2 does not work as expected. The behaviour after that line is still consistent with the original GetEnemies1 not GetEnemies2. how do I combat this problem?

• Load a Lua script into a table named after filename

  - by Homeliss

  I load scripts using luaL_loadfile and then lua_pcall from my game, and was wondering if instead of loading them into the global table, I could load them into a table named after their filename? For example: I have I file called "Foo.lua", which contains this: function DoSomething() --something end…
