At least one such template will be beyond the 500 EPFs/page limit in 2015. Clearly it's worth thinking about ways to reduce this impact as much as possible. may be relevant to this problem. Hex (? This makes dependencies between files hard to track and require you to manually execute some_class.lua before you can execute script.lua. 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:}}. Sandboxing is easy. is there a better way to do this? 2000 I think that this is less effective than it could be, however. A Go function should implement the LGFunction type to be callable from Lua. http://godoc.org/github.com/yuin/gopher-lua, http://github.com/otm/embedding-lua-in-go, http://godoc.org/github.com/yuin/gopher-lua#LTable. string.format('%f %f %f', 0.00001, 1.2, 3) => 0.000010 1.200000 3.000000, string.format('%g %g %g', 0.00001, 1.2, 3) => 1e-05 1.2 3, This page was last edited on 4 February 2023, at 15:13. A fixed size callstack has the highest performance and has a fixed memory overhead. --Iantresman (talk) 14:50, 8 December 2013 (UTC). There is still lots of work to do of course, But it's a start TheDJ (talk contribs) 22:18, 18 March 2013 (UTC). its number of parameters. --Iantresman (talk) 11:31, 9 December 2013 (UTC), Can modules "call" other modules? Ive used LuaDists CMake build scripts for Lua for many years, but LuaDist authors have stopped supporting newer Lua versions. --Jarekt (talk) 16:24, 14 March 2013 (UTC), Are module authors permitted to use other licenses (presumably in addition to the CC-BY-SA license) for modules they develop? Page contents not supported in other languages. Long story short, the overhead of a direct (non-virtual) function call was approximately 5.5 nanoseconds, or 18 clock cycles, compared to an inline function call. The overhead of a virtual function call was 13.2 nanoseconds, or 42 clock cycles, compared to inline. These timings are likely different on different processor families. itch.io was written with it and it compiles to vanilla Lua. It relies on Module:Sandbox/QuimGil/Flagicon, which provides the logics, and Module:Sandbox/QuimGil/FlagTranslations, where the flags data is stored. Hi, is there a way to instruct string.format to not produce trailing zeros with decimal notation? Frietjes (talk) 00:03, 4 July 2013 (UTC), At the moment we have the {{lua talk}} template to use on talk pages of templates converted to Lua. WebWhen iterating a table, the function overhead from ipairs does not justify it's use. Because it makes it much easier to track dependencies between various script files and makes them load each other when theyre needed. Text formatting (bold, italics) breaks when the ''/''' tags are not closed for each argument. 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. What am I doing wrong? Makyen, does that look something like what you wanted? Then, executing script.lua would resullt in an error: SomeClass is nil. I am trying to implement {{Horizontal timeline}} as a module. Is it a good idea to deviate from the template standard of calling pages with testcases, tests for the module namespace? Eg: {{example |row1 = {{template2|height=52}} }}, In the above exaple we can get row1 as frame.args.row1 but is it possible to get height from row1. Dcoetzee 23:09, 23 February 2013 (UTC), There's a discussion at the technical pump currently about where to put code that you're experimenting with; as a result Module:Sandbox has been created. To get the perf bit out of the way: the bridging code between C++/Lua has overhead compared to just calling Lua from Lua or calling C++ from C++. A surprisingly simple Lua compilerExtended version It has a GNU Make build, so building it is easy. Is this the right place for Lua programming queries? You can do procedural, functional, OO programming. Prompt and friendly service as well! You are free to edit the content of Wikipedia:Lua/To do during the discussion but should not remove the miscellany for deletion template from the top of the page; such a removal will not end the deletion discussion. I'd rather see useful LUA links. 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. powered by Hugo The tutorial I actually want is how a template with parser functions translate into a Lua module with explanation of what syntax equal what variable/function or whatever. See a simple example of how to build Lua with CMake and use it with sol2 here. lua a function definition has a conventional syntax; Is this a problem in my module or in Scribunto? Its much easier to test if something is non-nil or has a specific type/fields in Lua than in C++. That overhead might be removed if we made save/restore a built-in operation in Lua. Given that each {{#ifexist:}} is an expensive parser function (EPF), these templates can consume an excessive number of EPFs. Toohool (talk) 18:13, 15 March 2013 (UTC). With those it's not entirely clear if they are meant to go together or not. Download the official Lua source code here: https://www.lua.org/download.html. Hopefully this will be semi-useful again. Learn more. An expression like o:foo(x) An auto sizing callstack will allocate and release callstack pages on demand which will ensure the minimum amount of memory is in use at any time. Lua 5.4 FT2(Talk|email) 02:07, 20 March 2013 (UTC), I found this guide for learning how to code Lua, may be of help or use www.lua.org/pil/contents.html#P1, I feel like I must have reinvented the wheel here, but I copied Template:Tlx to Template:Mlx with minor modifications, so we can type, and get {{#invoke:ConvertNumeric|decToHex|99 33}}, It would be good if someone could look this over for any flaws before it gets cascade-protected by something. mw:Extension:Scribunto/Lua reference manual, Getting started ("hello world") portion of the Lua reference documentation, Sumana Harihareswara, Wikimedia Foundation Engineering Community Manager, MediaWiki:Scribunto-doc-page-does-not-exist. --Iantresman (talk) 13:14, 8 December 2013 (UTC). It Is Me Here t / c 15:08, 3 September 2013 (UTC). lua --SocietyBox (talk) 02:26, 20 January 2014 (UTC). Please take a look at Module:RepeatString and Template talk:Repeat and see what you think. How about expanding the template's function so that we can also put at the top of template /doc pages? There is no reason to do it for functions which are already lua Relevant to Lua, userscripts, and user scripting generally. If you notice that your C++ function has a huge overhead because of Lua calls, consider using this pattern: If you dont use local to define/init a variable, it becomes a global by default. WebLua programs can emit signals using the function call syntax. (and object-oriented programming) in more detail. At the moment, we have three patterns in naming a module sandbox page: I suggest that is one too much. Needs study to guarantee correctness! Timing Lua Code Correctly in OpenResty WebFunctions used by a Lua program can be defined both in Lua and in C (or in any other language used by the host application). Is these Lua performance tips still accurate? : r/lua - Reddit Keep your global state to a minimum and variable scope as small as possible. extra parameters get nil. I would welcome comments, and if people think the scheme is OK, please consider rating your modules Wnt (talk) 23:31, 16 April 2013 (UTC), I have opened a discussion here: en:Module_talk:String#Replication on other wikis. The documentation toolbox does not yet know about Module testcases (though the editnotice 'sort of' does). If needed, custom metadata can safely be written to the metadata table; it is unique for each key and will persist for the duration of the load() call. Using the L.CheckTypes function equate to checking the type manually and then calling L.TypeError(n int, message string) if there is an error. Wnt (talk) 15:52, 22 January 2014 (UTC), Wikipedia:Lua/To do, a page you substantially contributed to, has been nominated for deletion. now i wanted to translate Category:Pages with script errors in bn language. Your help pointing to ways to improve is welcome. a find-and-replace Macro that lets you write code that acts like a function, without the function overhead running an external image to lua tool, so you can just stick the images in your Project folder, and automatically include them into your lua script every time you hit F7 ! GitHub - Samur3i/direct-loader: Requires all Lua files in a You can easily print table contents with it: For example, Id recommend to avoid SDL/glfw/SFML bindings and writing them manually for the stuff you need. The syntax of the template sends another template as parameter. - basically everything else that doesnt interact with low-level OS APIs much. I've been trying to use some of the other frame functions, and I can get them working via #invoke, but not through the debug console. They are iteration functions, so they add the overhead of a function call to each loop iteration. Hence, for Lua, the alternative is to pass fewer parameters, but as strings of choices delimited by separator characters within each string. A language variable can contain values of any type. To iterate a table, instead use for k=1, #tbl do local v = tbl [k]; It does exactly the same without the function call overhead (pairs actually returns another function which is then called for I would use them again if needed. If nothing happens, download Xcode and try again. Isnt it great? I'd like to include some of the functionality of module:Page in my module, without having to reinvent the wheel. 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. Wnt thinks that the template should use the "style" type (with a yellow background), and I think it should use the "notice" type (with a grey background). Can one call lua function that returns sevaral strings and pass them to a template? OUR MISSION. Support for calling a parser function is coming soon with frame:callParserFunction, or you could do it today by passing the markup to frame:preprocess. To be sure, this is the strip marker for a current time function, but I'm thinking this is either a bug or a feature, and we should figure out which! For example, it is not printing the string "mw.site.currentVersion", and only two "mw.site.stats" table rows, which might suggest it is not recursing properly, or perhaps something else. (what is sometimes called procedure Its simple. Now the tab "Modules" does not show all modules, and does not have a 'next page' link.
