L'extension Scribunto (latin : "ils l'écriront/le laisseront écrire (à l'avenir)") permet l'intégration de langages de script dans MediaWiki. Actuellement, le seul langage de script pris en charge est Lua.


This extension contains code licensed GNU General Public License v2.0 or later (GPL-2.0+) as well as code licensed MIT License (MIT).


Compatibilité des versions PCRE

PCRE 8.33+ est recommandé. Vous pouvez voir la version de PCRE utilisée par PHP en affichant une page web phpinfo(), ou à partir de la ligne de commande avec la commande php -r 'echo "pcre: " . ( extension_loaded( "pcre" ) ? PCRE_VERSION : "no" ) . "\n";'.

CentOS 6 and RHEL 6 are stuck on PCRE 7 and need to be upgraded.

Mettre à jour vers la 8.33 peut s'avérer très compliqué avec un serveur ayant une version plus ancienne. Voir Mise à jour vers PCRE 8.33 ou supérieur pour les détails.

PHP pcntl (LTS)

Versions de MediaWiki : 1.25 – 1.28

Scribunto versions for MediaWiki 1.25 to 1.28 required PHP's pcntl extension, which is only available on Unix/Linux platforms, if you want to use "LuaStandalone" (i.e. running in a separate child process). Cette contrainte a été supprimée dans Scribunto pour MediaWiki 1.29.

Vous pouvez vérifier si pcntl est pris en charge en affichant une page web phpinfo() ou à partir de la ligne de commande en tapant php -r 'echo "pcntl: " . ( extension_loaded( "pcntl" ) ? "yes" : "no" ) . "\n";'.

PHP mbstring extension

PHP needs to have the mbstring extension enabled.

You can check whether mbstring support is enabled by viewing a phpinfo() web page, or from the command line with the command php -r 'echo "mbstring: " . ( extension_loaded( "mbstring" ) ? "yes" : "no" ) . "\n";'.

Lua binary

Bundled binaries

Scribunto comes bundled with Lua binary distributions for Linux (x86 and x86-64), Mac OS X Lion, and Windows (32- and 64-bit).

Scribunto should work for you out of the box if:

  1. Your web server is run on one of the above platforms.
  2. PHP's proc_open function is not restricted[1]
  3. Your web server is configured to allow the execution of binary files in the MediaWiki tree.
  Note : Execute permissions may need to be set; for example, in Linux use
chmod a+x /path/to/extensions/Scribunto/includes/engines/LuaStandalone/binaries/lua5_1_5_linux_64_generic/lua
If you are using SELinux in "Enforcing" mode on your server, you might need to set a proper context for the binaries. Example for RHEL/CentOS 7:
chcon -t httpd_sys_script_exec_t /path/to/extensions/Scribunto/includes/engines/LuaStandalone/binaries/lua5_1_5_linux_64_generic/lua

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.

  •   Fait – Accédez à Special:Version sur votre wiki pour vérifier que l'extension a bien été installée.

Pour les utilisateurs de MediaWiki 1.29 ou précédents :

Les instructions ci-dessus décrivent la nouvelle procédure pour installer cette extension en utilisant wfLoadExtension(). Si vous avez besoin d'installer cette extension sur les précédentes versions de MediaWiki (1.29 ou antérieur), à la place de wfLoadExtension( 'Scribunto' );, vous devez utiliser :

require_once "$IP/extensions/Scribunto/Scribunto.php";

Optional Installation

Integrating extensions

For a more pleasant user interface, with syntax highlighting and a code editor with autoindent, install the following extensions:

(MediaWiki 1.30 or earlier)Then in your LocalSettings.php after all the extension registrations, add:

$wgScribuntoUseGeSHi = true;
$wgScribuntoUseCodeEditor = true;


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 $wgScribuntoDefaultEngine = 'luasandbox';.


The following configuration variables are available:

Select the engine. Valid values are the keys in $wgScribuntoEngineConf, which by default are 'luasandbox' or 'luastandalone'.
When Extension:SyntaxHighlight is installed, set this true to use it when displaying Module pages.
When Extension:CodeEditor is installed, set this true to use it when editing Module pages.
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.


The following keys are used in $wgScribuntoEngineConf for Scribunto_LuaStandaloneEngine. Generally you'd set these as something like

$wgScribuntoEngineConf['luastandalone']['key'] = 'value';
Specify the path to a Lua interpreter.
Specify the path to a file, writable by the web server user, where the error and debugging output from the standalone interpreter will be logged.
Error output produced by the standalone interpreter are not logged by default. Configure logging with:
$wgScribuntoEngineConf['luastandalone']['errorFile'] = '/path/to/file.log';
Specify the memory limit in bytes for the standalone interpreter on Linux (enforced using ulimit).
Specify the CPU time limit in seconds for the standalone interpreter on Linux (enforced using ulimit).
Set true to allow use of setfenv and getfenv in modules.


The following keys are used in $wgScribuntoEngineConf for Scribunto_LuaSandboxEngine. Generally you'd set these as something like

$wgScribuntoEngineConf['luasandbox']['key'] = 'value';
Specify the memory limit in bytes.
Specify the CPU time limit in seconds.
Specify the time between polls in sections for the Lua profiler.
Set true to allow use of setfenv and getfenv in modules.


Scripts go in a new namespace called Module. Each module has a collection of functions, which can be called using wikitext syntax such as:

 {{#invoke: Module_name | function_name | arg1 | arg2 | arg3 ... }}


Learning Lua

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:

The reference manual is also useful:

Lua environment

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.

The environment which scripts run in is not quite the same as in standard Lua. These differences are noted in Special:MyLanguage/Extension:Scribunto/Lua reference manual#Differences from standard Lua.

Debug console

Debug console usage example
See also Extension:Scribunto/Debug console

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 using the clickable "Script error" link.

Note that red Lua error messages are clickable and will provide more detailed information.

Lua error: Internal error: The interpreter exited with status 1

When using the LuaStandalone engine (this is the default), errors along the lines of "Lua error: Internal error: The interpreter exited with status 1" 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".

Lua error: Internal error: The interpreter exited with status 2

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:

$wgScribuntoEngineConf['luastandalone']['memoryLimit'] = 209715200; # bytes

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: The interpreter exited with status 24

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 Phabricator and participate in determining why the XCPU signal isn't being caught.

Lua error: Internal error: The interpreter exited with status 126

When using the LuaStandalone engine (this is the default), errors along the lines of "Lua error: Internal error: The interpreter exited with status 126" may be generated if the standalone Lua interpreter cannot be executed. This generally arises from either of 2 causes:

  • The lua executable file's permissions do not include Execute. Set permissions as described under #Installation.
  • 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.
