Scribunto(라틴어로 적도록 도와주다라는 의미의 낱말)란 미디어위키 내에서 구문을 (위키내에 내장된 컴퓨터로 작동시킨다는 의미의) 임베딩을 가능하도록 도와주는 확장기능입니다.
현재는 Lua라는 프로그래밍 언어로만 지원하고 있습니다.
Scribunto가 적용되었다는 건, Lua를 모듈이라는 이름공간안에서 작성하는 것이 가능하다는 의미입니다.
Modules are run on normal wiki pages using the #invokeparser function and each module has a collection of functions, which can be called using wikitext syntax such as:
Vagrant를 사용하고 있는 경우에는, vagrant roles enable scribunto --provision로 설치해주세요
Requirements
PCRE version compatibility
PCRE 8.33+ is recommended.PCRE 8.33 was released in May 2013.You can see the version of PCRE used by PHP by viewing a phpinfo() web page, or from the command line with the following command:
P.S. Check your version of the extension to see if the name of the engines folder is capitalised or fully lowercase.[2]
Additional binaries
Additional Lua binary distributions, which may be needed for your web server if its operating system is not in the list above, can be obtained from http://luabinaries.sourceforge.net/ or from your Linux distribution.
Only binary files for Lua 5.1.x are supported.
Once you've installed the appropriate binary file on your web server, configure the location of the file with:
# Where Lua is the name of the binary file# e.g. SourceForge LuaBinaries 5.1.5 - Release 2 name the binary file lua5.1$wgScribuntoEngineConf['luastandalone']['luaPath']='/path/to/binaries/lua5.1';
Note that you should not add the above line unless you've confirmed that Scribunto's built-in binaries don't work for you.
LuaJIT, although theoretically compatible, is not supported.
See the documentation for each extension for additional configuration options.
LuaSandbox
We have developed a PHP extension written in C called LuaSandbox.It can be used as an alternative to the standalone binary, and will provide improved performance.See LuaSandbox for details and installation instructions.
If you initially installed the extension to use the Lua standalone binary, be sure to update LocalSettings.php with the following configuration setting:
$wgScribuntoDefaultEngine='luasandbox';
Configuration
The following configuration variables are available:
$wgScribuntoDefaultEngine
Select the engine.Valid values are the keys in $wgScribuntoEngineConf, which by default are 'luasandbox' or 'luastandalone'.
$wgScribuntoEngineConf
An associative array for engine configuration.Keys are the valid values for $wgScribuntoDefaultEngine, and values are associative arrays of configuration data.Each configuration array must contain a 'class' key naming the ScribuntoEngineBase subclass to use.
LuaStandalone
The following keys are used in $wgScribuntoEngineConf for Scribunto_LuaStandaloneEngine.Generally you'd set these as something like
Lua is a simple programming language intended to be accessible to beginners.For a quick crash-course on Lua, try Learn Lua in 15 Minutes.
The best comprehensive introduction to Lua is the book Programming in Lua.The first edition (for Lua 5.0) is available online and is mostly relevant to Lua 5.1, the version used by Scribunto:
In Lua, the set of all global variables and functions is called an environment.
Each {{#invoke:}} call runs in a separate environment.Variables defined in one {{#invoke:}} will not be available from another.This restriction was necessary to maintain flexibility in the wikitext parser implementation.
When editing a Lua module a so-called "debug console" can be found underneath the edit form.In this debug console Lua code can be executed without having to save or even create the Lua module in question.
Troubleshooting
Troubleshooting using the clickable "Script error" link.
Note that red 스크립트 오류 messages are clickable and will provide more detailed information.
When using the LuaStandalone engine (this is the default), errors along the lines of "Lua 오류: 내부 오류: 인터프리터가 1 상태로 종료했습니다." may be generated if the standalone Lua interpreter cannot be executed or runs into various runtime errors.To obtain more information, assign a file path to $wgScribuntoEngineConf['luastandalone']['errorFile'].The interpreter's error output will be logged to the specified file, which should prove more helpful in tracking down the issue.The information in the debug log includes debugging information, which is why there is so much of it.You should be able to ignore any line beginning with "TX" or "RX".
If you're setting up Scribunto and are using IIS/Windows, this appears to be solved by commenting out line 132 in $wiki/extensions/Scribunto/includes/engines/LuaStandalone/LuaStandaloneInterpreter.php.
In other words, change $cmd = '"' . $cmd . '"'; to // $cmd = '"' . $cmd . '"';.
Lua 오류: 내부 오류: 인터프리터가 2 상태로 종료했습니다.
When using the LuaStandalone engine (this is the default), status 2 suggests memory allocation errors, probably caused by settings that allocate inadequate memory space for PHP or Lua, or both.Assigning a file path to $wgScribuntoEngineConf['luastandalone']['errorFile'] and examining that output can be valuable in diagnosing memory allocation errors.
Increase PHP allocation in your PHP configuration; add the line memory_limit = 200M.This allocation of 200MB is often sufficient (as of MediaWiki 1.24) but can be increased as required.Set Scribunto's memory allocation in LocalSettings.php as a line:
Finally, depending on the server configuration, some installations may be helped by adding another LocalSettings.php line
$wgMaxShellMemory=204800;# in KB
Note that all 3 memory limits are given in different units.
Lua error: Internal error: 2. on ARM architecture
If you're using an ARM architecture processor like on a RaspberryPi you'll face the error Lua error: Internal error: The interpreter exited with status 2. due to wrong delivered binary format of the Lua interpreter.
lua: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0
The installed default Lua interpreter shows:
lua: ELF 32-bit LSB pie executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.9,
look at the "Intel 80386" part what definitely is not correct.
Check in /usr/bin what version of Lua is installed on your system.If you have lua5.1 installed, you can either copy the interpreter to your lua5_1_5_linux_32_generic directory or set in your LocalSettings.php:
At present don't set wgScribuntoEngineConf to /usr/bin/lua5.3, it'll lead to the "Internal error 1".
Lua 오류: 내부 오류: 인터프리터가 24 상태로 종료했습니다.
When using the LuaStandalone engine (this is the default), status 24 suggests CPU time limit errors, although those should be generating a "The time allocated for running scripts has expired" message instead.It would be useful to file a task in 파브리케이터 and participate in determining why the XCPU signal isn't being caught.
Lua 오류: 내부 오류: 인터프리터가 126 상태로 종료했습니다.
When using the LuaStandalone engine (this is the default), errors along the lines of "Lua 오류: 내부 오류: 인터프리터가 126 상태로 종료했습니다." may be generated if the standalone Lua interpreter cannot be executed.This generally arises from either of two causes:
The Lua executable file's permissions do not include Execute.
The server does not allow execution of files from the place where the executable is installed, e.g. the filesystem is mounted with the 'noexec' flag.
This often occurs with shared hosted servers.Remedies include adjusting $wgScribuntoEngineConf['luastandalone']['luaPath'] to point to a Lua 5.1 binary installed in an executable location, or adjusting or convincing the shared host to adjust the setting preventing execution.
Error condition such as: Fatal exception of type MWException
Check the MediaWiki, PHP, or webserver logs for more details on the exception, or temporarily set $wgShowExceptionDetails to true.
version 'GLIBC_2.11' not found
If the above gives you errors such as "version 'GLIBC_2.11' not found", it means the version of the standard C library on your system is too old for the binaries provided with Scribunto.You should upgrade your C library, or use a version of Lua 5.1 compiled for the C library you do have installed.To upgrade your C library, your best option is usually to follow your distribution's instructions for upgrading packages (or for upgrading to a new release of the distribution, if applicable).
If you copy the lua binaries from Scribunto master (or from gerrit:77905), that should suffice, if you can't or don't want to upgrade your C library.The distributed binaries were recently recompiled against an older version of glibc, so the minimum is now 2.3 rather than 2.11.
Lua errors in Scribunto files
Errors here include:
attempt to index field 'text' (a nil value)
Lua error in mw.html.lua at line 253: Invalid class given:
If you are getting errors such these when attempting to use modules imported from WMF wikis, most likely your version of Scribunto is out of date.
Upgrade if possible; for advanced users, you might also try to identify the needed newer commits and cherry-pick them into your local installation.
preg_replace_callback(): Compilation failed: unknown property name after \P or \p at offset 7
preg_replace_callback(): Compilation failed: unknown property name after \P or \p at offset 7
this usually indicates an incompatible version of PCRE; you'll need to update to >= 8.10
@todo: link to instructions on how to upgrade
Lua error
If you copy templates from Wikipedia and then get big red "Lua error: x" messages where the Scribunto invocation (e.g. the template that uses {{#invoke:}}) should be, that probably means that you didn't import everything you needed.Make sure that you tick the "Include templates" box at w:Special:Export when you export.
When importing pages from another wiki, it is also possible for templates or modules in the imported data to overwrite existing templates or modules with the same title, which may break existing pages, templates, and modules that depend on the overwritten versions.

Capiunto - Provides basic infobox functionality for the Scribunto extension.
↑i.e. Scribunto will not work if proc_open is listed in the disable_functions array in your server's "php.ini" file.If it is, you may see an error message like proc_open(): open_basedir restriction in effect. File(/dev/null) is not within the allowed path(s):.If you are using Plesk and have been granted sufficient permissions, you may be able to set open_basedir in the PHP settings for your domain or subdomain.Try changing {WEBSPACEROOT}{/}{:}{TMP}{/} to {WEBSPACEROOT}{/}{:}{TMP}{/}{:}/dev/null{:}/bin/bash.
