What do people think? Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Vanilla Lua, the latest version, otherwise. Johnuniq (talk) 02:22, 25 June 2013 (UTC). I ran some local tests and it seems pretty easy to crash it, but then again I'm running it in an unstable environment anyway so it may not reflect how things work here on Wikipedia. In our C++ file, we need to define the consoleLog function that it will receive from JavaScript. The general method that has been used is to assume a format for the page archive name and then test for the existence of all such possible pages using {{#ifexist:}}. The process was smooth and easy. functions If you create a local object inside the coroutine and store the reference to it in C++. Ultimately MediaWiki should issue another tutorial for Wikipedians (without prior knowledge of C and Lua) due to the differences from standard Lua. Thank you. Text formatting (bold, italics) breaks when the ''/''' tags are not closed for each argument. The parameters object takes three important parameters: Fn - the lua.LFunction to call Nret - The number of returned values Protect - If protect is true an error is returned, otherwise a panic will occur. In Chapter 16 we will discuss such calls You can call it with LuaJITs FFI, see the tutorial here. Currently it is misleading advising to check for double redirects. I measured the overhead of direct and virtual C++ function calls on the Xenon PowerPC some time ago. This bytecode is converted into LLVM IR and then fed into Deegen, which can transform the functions to do tail calls correctly, use the GHC calling conventions, and a Just some of our awesome clients tat we had pleasure to work with. How do I fix this? Dont forget that you can do this: Now, when you load/execute this script, you will only get one function as the result: All the internal script state will be hidden and non-modifable and wont overwrite any global state in your current Lua state, which is great. WebIt's more terse, though at the expense of the function call overhead. Are you sure you want to create this branch? However, if we standardize this, with the names copied verbatim and the fairly distinctive capital letter after the /, it should be easy to have a bot notify the author(s) of Module:Submit an edit request automatically when Redirect is updated. Lua WebTo call a Lua funcion, we first push the function onto the stack. Installation You can download the latest release manually and include You can download the latest release manually and include it in your project, or you can install it in your project directory through Luvit's package manager Lit, using the install command. It's just that a central repository would be so beneficial for everybody (en.wiki devs/editors included) and en.wiki can't really be (in my honest and personal opinion) that place. now i wanted to translate Category:Pages with script errors in bn language. What am I doing wrong? Redis Lua API reference | Redis Toohool (talk) 18:13, 15 March 2013 (UTC). Incnis Mrsi (talk) 11:59, 2 July 2013 (UTC), Hi, your feedback is welcome at Bug 50329 - We need a common repository for Scribunto modules and templates. Thank you!--QuimGil (talk) 07:52, 21 June 2013 (UTC). We have an even split on people who do personal testing in Sandbox/ and people who do it in User: At this point, either of us could pull up stakes and migrate to the other pretty easily. Wikipedia talk:Lua/Archive 1 The XLua object also has a substantial MMF Interface for directly querying and modifying game objects and state Also, this page should explain that it is not possible to move a module to another namespace or vice versa, except doc pages (I think). Makyen(talk) 04:02, 8 May 2014 (UTC), I've heard for quite a while that the Lua scripts only run when the page is parsed, which rules out many interactive features but is efficient. Given that each {{#ifexist:}} is an expensive parser function (EPF), these templates can consume an excessive number of EPFs. Wnt (talk) 23:14, 21 March 2013 (UTC), I have run many timing tests, to compare using shell templates which contain #invoke versus direct use of {#invoke:}, and for tiny templates, such as string-handling functions, the template versions often ran upto 50% slower than direct #invoke of each tiny Lua function. The second clause supports a simple way to invoke the function from another module (such as from Module:Navbox), or from the debug console: Navbar.navbar({arg1 = 'foo', arg2 = 'bar'});. Hopefully this will be semi-useful again. Iterative multi-file loader, used to load all Lua modules in a directory and return them as one table. Is this the right place for Lua programming queries? Hard working, fast, and worth every penny! John Victor - via Google, Very nice owner, extremely helpful and understanding Incnis Mrsi (talk) 22:46, 9 January 2014 (UTC). its number of parameters. Formula: Lua Now, with this new LUA language, template editing is becoming more and more the domain of technicians. Currently, there are a reasonable number of templates that try to determine if any of a set of pages exist in order to provide links to those pages. Its simple. Older versions of Lua created empty tables with some pre-all ocated slots (four, if I We could also use the template to automatically add Category:Lua-based templates to keep track of converted templates more easily. n If you wish to retain the metadata for logging or other purposes, the entire metadata table is returned as the third return value from load(), containing the metadata for every key that was operated on (including those with no conflicts). So its better to do it on Lua side, unless you make a C++ API which has to accept tables for ease-of-use - then you dont have much choice (but you can still wrap them into Lua functions and call C++ function internally). I think that this is less effective than it could be, however. The functions in question had a single parame sign in They are iteration functions, so they add the overhead of a function call to each loop iteration. WebThe Lua interpreter offers two hooks for debug purposes: typedef void (*lua_CHFunction) (lua_Function func, char *file, int line); extern lua_CHFunction lua_callhook; typedef void (*lua_LHFunction) (int line); extern lua_LHFunction lua_linehook; The first one is called whenever the interpreter enters or leaves a function. !) 16:39, 24 February 2013 (UTC), the following code is arguably better than the current one;-) [Note: It also highlights more Lua features - assertion, type checking, local scoping, tail call recursion etc. That is partly about performance but mostly about engine architecture. The downside is it will incur a small performance impact every time a new page of callframes is allocated. A tag already exists with the provided branch name. You choose what Lua code can and cant do. . If nothing happens, download Xcode and try again. itch.io was written with it and it compiles to vanilla Lua. Then, see if you really need to move this code (or parts of it) to C++. Isnt it great? If you notice that your C++ function has a huge overhead because of Lua calls, consider using this pattern: // in C++ sol::table t = lua.create_table (); for (int i = 0; i < 1000; i++) { // do stuff in C++, push data to Lua table occasionally } luaFunc (t); -- in Lua function someFunc (t) for k,v in pairs (t) do -- do stuff end end 5. ], So templates can call Lua modules, parser functions and pages in MediaWiki namespace. lua.LVAsString(v LValue) - Converts LString and LNumber to string. Immediately afterward it gives you another line of codes which I have absolutely no idea where to insert it to make it functional at all. Download the official Lua source code here: https://www.lua.org/download.html. The value of any of these keys will never be. --Rotpunkt (talk) 12:35, 1 May 2013 (UTC), Hello, I'm wondering if there is currently a module that counts elements on a page. It has a GNU Make build, so building it is easy. For optional arguments the L.Opt(n int, default T) functions can be used. Otherwise true. We have a lot of cases where related modules have the same name with "/" to indicate subpages, and some others where apparently related modules simply extend a name. Extra arguments are thrown away; for example, make this work without copying the args to a new table? That is partly about performance but mostly about engine architecture. It receives a *lua.LState and returns an integer. : Overusing them makes code harder to understand because now you need to make sure that the object youre are pointing to doesnt change unexpectedly. Functions are the main mechanism for abstraction of statements The function signature must match what you passed in. Mr. Stradivarius talk 23:06, 1 January 2014 (UTC); Page moved without redirect. See the explanation on how to do concurrency in Lua in sol2 here (especially about lua_xmove and sol::main_object). The simplest way to time some Lua code is to use the time command with the resty command. Or is it something else? The same can be said about making your program expandable with plugins. Plastikspork (talk) 22:08, 2 November 2013 (UTC), I've created Module:Pagetype, a replacement for {{pagetype}}, and I am thinking of updating the template to the Lua version later on this week. --Iantresman (talk) 14:50, 8 December 2013 (UTC). To get automatic errors the L.Check(n int) family of functions can be used; They throw a Lua error if the type check fails. However, the basic API is quite simple, and the advanced features deserves its own post. Hex (? Please take a look at Module:RepeatString and Template talk:Repeat and see what you think. - basically everything else that doesnt interact with low-level OS APIs much. powered by Hugo Have there been any major incidents yet? 7.3 Hooks Will your logo be here as well?. Is there a programme wizard who can help see if I've done something stupid? -DePiep (talk) 23:30, 19 July 2013 (UTC), Do Module:WikiLink and voy:ru::Wikilinks effectively aim to do the same thing? These variables are called the formal parameters of the function. The formal parameters behave like other local variables inside the function and are created upon entry into the function and destroyed upon exit. While creating a Lua function, you give a definition of what the function has to do. However, sometimes that is just not enough and an embedded language can be the solution. Local declaration of (built-in) Lua functions to reduce also, if someone already wrote a module that does the same thing, let me know and I will have this one deleted. Thank you for your attention!--Qgil (talk) 21:16, 2 July 2013 (UTC), I created Module:Testcase table, and it seems to work pretty well (see the current transclusions). Does mw.ustring.byteoffset work correctly with negative offsets? Often the linked module contains bells and whistles that aren't really necessary; why not bring it into the module and slim it down? Calling Lua code is done through L.CallByParam, which takes a parameters object, P, and arguments as variadic parameters. Prompt and friendly service as well! Gut feeling is usually wrong. When programming in Lua, you may use constructors to avoid th ose initial rehashings. When you write {true, true, true} , Lua knows beforehand that the table will need three slots in its array part, so Lua creat es the table with that size. Makyen, does that look something like what you wanted? If youre writing a game and want to make it possible for people to create mods, many of your players are likely to know Lua thanks to such games as Minecraft, Factorio, Garrys Mod, World of Warcraft, Roblox and. When calling a function, At Module:DisplayLuaTableContents I see numerous loops as, , but I learned that strings are immutable and hence this assignment is rather costly. If nothing happens, download GitHub Desktop and try again. Does this apply if you are accessing the module from another Lua module, and not directly from a wiki page? Youre unlikely to run into performance issues, unless youre making a AA/AAA game or a complex simulation program. the colon operator. WebWe can disable all the type checking by switching a single variable, and no added overhead would remain when the functions are executed (though there is some slight added overhead when the functions are built). To get the perf bit L.DoString runs the Lua code in the VM. How to implement action sequences and cutscenes in Lua, Making and storing references to game objects (entities) in C++ and Lua, https://www.lua.org/manual/5.4/manual.html#4. I was just trying to return those hex tables via loadData and seem to have run into a nasty surprise. Also, your feedback here about the best way to organize the data is also welcome. if u can help me)I imported Module:Citation, Module:Citation/CS1/Configuration, Module:Citation/CS1 in bn.wikipedia. --Aftab1995 (talk) 15:50, 23 May 2013 (UTC), I'm very happy to announce that Template:FlagiconLua has reached feature parity with Template:Flagicon! Everyone took really good care of our things. See a simple example of how to build Lua with CMake and use it with sol2 here. that is, to call o.foo adding o as a first extra argument.
