WebWhen iterating a table, the function overhead from ipairs does not justify it's use. It is superfluous if you only call the function once within the scope of the local variable, but that is pretty rare. In short, if your coroutine gets GCed and you hold the reference to this local variable as a sol::object on the C++ side, it wont prevent the variable from getting GCed by Lua and your program crashing because of that. 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. They have lots of options for moving. There are a number of To(n int) functions available. Calling Lua code is done through L.CallByParam, which takes a parameters object, P, and arguments as variadic parameters. Does mw.ustring.byteoffset work correctly with negative offsets? Mr. Stradivarius talk 16:45, 29 March 2013 (UTC), I decided to implement a Lua replacement for the innards of {{Repeat}} as a learning project for my first Lua module. (At least script error should be shown when print function is detected.) Please At the moment, we have three patterns in naming a module sandbox page: I suggest that is one too much. if u can help me)I imported Module:Citation, Module:Citation/CS1/Configuration, Module:Citation/CS1 in bn.wikipedia. --HectorMoffet (talk) 11:05, 29 December 2013 (UTC). If a conflict can not be resolved in a satisfactory manner, the function should throw an error to signify this; returning false or nil will result in that value being written to the key. The sandbox Wiki code {{Special:AllPages|namespace=666}} {{CURRENTTIMESTAMP}} returns a timestamp that changes each time the page is reloaded, because caching is disabled. With those it's not entirely clear if they are meant to go together or not. Local declaration of (built-in) Lua functions to reduce Its easy to integrate Lua scripts into C/C++ projects. Servicing Stanislaus, San Joaquin and Merced Counties, 2209 Fairview Drive Suite A Ceres, CA 95307. John Victor - via Google, Very nice owner, extremely helpful and understanding 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. 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. You might also find Moonscript interesting. Ultimately MediaWiki should issue another tutorial for Wikipedians (without prior knowledge of C and Lua) due to the differences from standard Lua. 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. 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. Is this the right place for Lua programming queries? Lua is a language with implicitly dynamic data types. What is the equivalent of {{fullurl:page name}}? with nil arguments removed. Timing Lua Code Correctly in OpenResty its number of parameters. Lua has eight basic types: nil (undefined) boolean (boolean) number (numeric) string (string) I'd rather see useful LUA links. Iterative multi-file loader, used to load all Lua modules in a directory and return them as one table. I am trying to create a weblink by concatenating 2 strings and by avoiding the display of the full link in an infobox. d That way it would be obvious straight away which templates have been converted, and would help advertise the fact that we have this neat new programming language available and that we need people to convert existing templates over. Stormworks Lua with LifeBoatAPI These functions does not throw errors, but will return Go default values if conversion is not possible. Johnuniq (talk) 02:22, 25 June 2013 (UTC). Calling the LValue.Type() returns the corresponding LValueType. The reference manual for Lua 5.4s C API is here: https://www.lua.org/manual/5.4/manual.html#4, Github repo: https://github.com/ThePhD/sol2. Reinterpreting The Lua Interpreter | Hackaday Maybe. The compiler might decide "hey, this function is only called a few times, and I'm supposed to optimize for speed, so I'll just inline this f I'm thinking by this point that it would be better to just develop an explicit tool to control caching, and some mechanisms (if they don't already exist) to audit what pages are not cached and identifying the worst reloaders) Wnt (talk) 15:48, 13 January 2014 (UTC). You just compile a bunch of C files, link with the library and youre ready to go - you dont need to rewrite half of your program/game or make your build script 10 times more difficult. mw:Extension:Scribunto/Lua reference manual#mw.title.makeTitle, en:Module_talk:String#Replication on other wikis, http://commons.wikimedia.org/wiki/Commons:Lua/Modules, Help talk:Template#Counting items in numbered list, WT:WikiProject Templates#Counting items in numbered list, Wikipedia:Help desk#Counting items in numbered list, betawiki:MediaWiki:Scribunto-common-error-category/bn, mediawikiwiki: Extension:Scribunto/Lua reference manual #table.concat, Bug 50329 - We need a common repository for Scribunto modules and templates, Template:Year in other calendars/testcases, Module talk:Sandbox/Johnuniq/grosstonnage, Wikipedia talk:Lua style guide#CodeEditor switched to tabs, submit code to implement a ulimit-like mechanism on Windows, Special:WhatLinksHere/3000 United States Census, mw:Extension:Scribunto/Lua_reference_manual#Returning_text, Module:Sandbox/iantresman/sandbox/archive/mw.recursive, User:Iantresman/sandbox/archive/mw.recursive, Special:PrefixIndex/User:Mr. Stradivarius, Help:Lua_for_beginners#Initializing_a_table, updating some Lua modules can cause 7 million pages to be reformatted, Template_talk:Convert#Deploying updates now 18,000x slower, Wikipedia:Miscellany for deletion/Wikipedia:Lua/To do, https://en.wikipedia.org/w/index.php?title=Wikipedia_talk:Lua/Archive_1&oldid=1137418039, Creative Commons Attribution-ShareAlike License 3.0. You can do procedural, functional, OO programming. Anyone interested in testing templates may want to try Module:Convert/tester which allows hundreds of tests to be easily defined. Then we call the function with lua_call ().
