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. Older versions of Lua created empty tables with some pre-all ocated slots (four, if I I did not see any mention of this in the tutorial.--greenrd (talk) 10:04, 19 October 2013 (UTC), I've started up a new discussion about this at Wikipedia talk:Lua style guide#CodeEditor switched to tabs. --Iantresman (talk) 00:06, 12 December 2013 (UTC). A Go function should implement the LGFunction type to be callable from Lua. Thats basically all youll ever need to know about Lua. While still largely relevant for later versions, there are some differences.The fourth edition targets Lua 5.3 and is available at Amazon and other bookstores.By buying the book, you also help to support the Lua project. Text formatting (bold, italics) breaks when the ''/''' tags are not closed for each argument. 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 A fixed size callstack has the highest performance and has a fixed memory overhead. Iterative multi-file loader, used to load all Lua modules in a directory and return them as one table. Because the property from Wikidata is not updated by mw.message, I decided to try it on one of those pesky Special: pages that abolish caching. Gut feeling is usually wrong. lua.LVIsFalse(v LValue) - Returns true if nil or false. I'd like to include some of the functionality of module:Page in my module, without having to reinvent the wheel. My own modules populate only the pre-alpha and alpha categories, but there are some here which I know have reached the other levels. Anomie 03:36, 1 November 2013 (UTC), User:Wnt and I have had a little disagreement over the type parameter of the {{lua}} template. Easy to start using, the interface is user friendly and feels similar to C++ standard library. I don't know, but with some of these things being transcluded on every page in the wiki, and having elaborate powers to write anything they can slip by the interface, we should be wary of security holes, and the first step is to know quickly and certainly which are a unit, I think. If you think that your game became slow because of Lua code, profile first before rewriting it in C++. I was going to deploy it on Template:Year in other calendars/testcases, but in my preview it runs out of time by the time it gets to the last test. A surprisingly simple Lua compilerExtended version The returned integer defines how many return values has been pushed to the Lua stack. We could also use the template to automatically add Category:Lua-based templates to keep track of converted templates more easily. If nothing happens, download GitHub Desktop and try again. 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. Mr. Stradivarius talk 01:15, 29 October 2013 (UTC), How well does Scribunto defend itself against DoS, or possibly XSS, but especially DoS as we are dealing with a Turing-complete language? If you used classes as globals (which Ive seen in many tutorials and real code), you might have a script like this: Suppose that you didnt execute some_class.lua first (which defines a global SomeClass). The documentation toolbox does not yet know about Module testcases (though the editnotice 'sort of' does). Download the official Lua source code here: https://www.lua.org/download.html. Given an instance myqobject of this class, a Lua program can emit signal mysignal as follows Can someone make a nice SpecialPages adjustment? 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. The syntax of the template sends another template as parameter. thank you. With your own bindings, you can control what version you use and how the exposed API looks in Lua. This was possible because the wikimarkup language was very intuitive, and easy to understand even for the layman. If you're a Lua developer, please watchlist it. ", [ [\w+\. I know we are quite far into WP:DEW territory here, but I'd appreciate it if people could comment at the discussion over at Template talk:Lua#Style. There was a problem preparing your codespace, please try again. Felicia Hagler - via Google, In the middle of a big move and so far Jay Casey has been immensely helpful to us with all the details! Does someone have an idea how to code this feature? 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. Then, executing script.lua would resullt in an error: SomeClass is nil. (and object-oriented programming) in more detail. To simplify comparisons, when comparing metadata the following can always be assumed to be true: From this data or according to any other criteria, the handler function should resolve the conflict by returning the value that should be written to the conflicted key. In this case we will embed Lua using gopher-lua. --Iantresman (talk) 14:50, 8 December 2013 (UTC). Stormworks Lua with LifeBoatAPI Then, see if you really need to move this code (or parts of it) to C++. 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. There are some practical functions to convert and check lua.LValue objects. Can templates, MediaWiki pages or parser functions be called from Lua? WebDue to the short-circuiting behavior of or, it will generally impose little additional overhead at call-time: local soundit; do local sounds; function soundit (x) sounds = sounds or { a = "ay" , b = "bee" , c = "see" , . } assert ( type (x) == "string" ) return sounds [x] end end
