WebBut when you create thou sands of small tables, the combined overhead can be signic ant. However, after writing up Module:Hex, which hex dumps the contents of strings, I was looking at the talk page when I noticed that the hex-dump of the contents of a strip marker (the example with UNIQ QINU) are changing every single time I hit the Talk tab or browser reload button to reload the page, even when I'm completely logged out with scripts disabled! If those restrictions are not a problem, the new tester provides a convenient way to set up tests on any page, for example: If the above tests were at page "Template:Example/tests", the following would insert a table showing the results of expanding each template and comparing its output with the expected text. lua.LVIsFalse(v LValue) - Returns true if nil or false. Or is it something else? This concept might be extended to support more than one memory location: Is a module supposed to do something clever in order to output tags? Thanks! Now the tab "Modules" does not show all modules, and does not have a 'next page' link. You choose what Lua code can and cant do. is to create and maintain customer confidence with our services and communication. Cya. I'm a happy user of this space myself with the pet projects I develop in my free time. 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. I tried to start learning Lua and immediately hit the wall after the "hello, world" part and all I got afterward are "script error". In brief, the categories I set up were pre-alpha, alpha, beta, release, and protected. Then we call the function with lua_call (). You can do procedural, functional, OO programming. Any suggestion on how to receive this parameter template as a table rather than a substituted string? Please take a look at Module:RepeatString and Template talk:Repeat and see what you think. The less data is shared between C++ and Lua, the better. Functions used by a Lua program can be defined both in Lua and I measured the overhead of direct and virtual C++ function calls on the Xenon PowerPC some time ago. 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. Its much easier to test if something is non-nil or has a specific type/fields in Lua than in C++. 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! 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. Clearly it's worth thinking about ways to reduce this impact as much as possible. *, I'd like to find out which mw.site library options are available, and print their value, without having to specify each one individually, ie. You dont need to compile Lua code, which means that you can change parts of your program/game logic without recompiling and even without reloading your program. It doesnt have many gotchas. 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. DePiep (talk) 23:55, 21 May 2015 (UTC). 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. A complete example looks like this: The LState defines some convenience functions, in the example above we are using L.ToInt(1) to fetch the first function argument. That's a bit of boilerplate code that I've been using in all the modules I write. Ive written many articles about using Lua with C++ on my old blog many years ago. However, the basic API is quite simple, and the advanced features deserves its own post. Note: Lua isnt zero-indexed, so the first function argument is fetched with L.ToInt(1), second argument with L.ToInt(2). The message from MediaWiki:Movepagetext-noredirectfixer should warn about this, perhaps a warning like MediaWiki:Moveuserpage-warning. 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. You can divide up your code into separate functions. Your opinions on the matter are welcome; please participate in the discussion by adding your comments at Wikipedia:Miscellany for deletion/Wikipedia:Lua/To do and please be sure to sign your comments with four tildes (~~~~). a function definition has a conventional syntax; Hi, is there a way to instruct string.format to not produce trailing zeros with decimal notation? That would only apply to your contributions though, not to later modifications made by other editors. If that is not possible: Please suggest an alternative method to implement it. Formula: 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.
