問題点 未解決のタスク · バグを報告

The Scribunto (Latin: "they shall write/let them write (in the future)") extension allows for embedding scripting languages in MediaWiki.

Currently the only supported scripting language is 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).


PCRE version compatibility

PCRE 8.33+が推奨されます。 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:

php -r 'echo "pcre: " . ( extension_loaded( "pcre" ) ? PCRE_VERSION : "no" ) . "\n";'
  • Scribunto will not work with versions of PCRE lower than 8.10.

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

Updating to 8.33 on a server with an older version may be relatively complicated. See Updating to PCRE 8.33 or Higher for details.

PHP演算子 (LTA)

MediaWiki バージョン:
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). これはMediaWiki 1.29で削除されました。

pcntlサポートが有効かどうかは、phpinfo()のウェブページを見るか、以下のコマンドで確認できます :

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 following 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.
  注: Execute permissions may need to be set; for example, in Linux use
chmod 755 /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.

LuaJIT, although theoretically compatible, is not supported. The support was removed due to Spectre and bitrot concerns (phab:T184156).


  • Vagrant を使用している場合は、vagrant roles enable scribunto --provision でインストールしてください
  • ダウンロードして、ファイルを extensions/ フォルダー内の Scribunto という名前のディレクトリ内に配置します。
  • 以下のコードを LocalSettings.php の末尾に追加します:
    wfLoadExtension( 'Scribunto' );
    $wgScribuntoDefaultEngine = 'luastandalone';
  • Set execute permissions for the Lua binaries bundled with this extension:
chmod a+x /path/to/extensions/Scribunto/includes/engines/LuaStandalone/binaries/yourOS/lua
  • Set type to httpd_sys_script_exec_t if SELinux is enforced:
chcon -t httpd_sys_script_exec_t /path/to/extensions/Scribunto/includes/engines/LuaStandalone/binaries/yourOS/lua
  •   完了 – ウィキの「Special:Version」に移動して、拡張機能が正しくインストールされたことを確認します。

MediaWiki 1.29 以前を稼働させている利用者へ:

上記の手順では、wfLoadExtension() を使用してこの拡張機能をインストールする新しい方法を記載しています。 この拡張機能をこれらの過去のバージョン (MediaWiki 1.29 以前) にインストールする必要がある場合は、wfLoadExtension( 'Scribunto' ); の代わりに以下を使用する必要があります:

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;


LuaSandboxというC言語で書かれたPHP拡張機能を開発した。 standalone binaryの代わりに使用でき、パフォーマンスが向上します。 詳細と導入方法についてはLuaSandbox を参照して下さい。

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:

エンジンを選択します。 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']['キー'] = '値';
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 ... }}



Luaはシンプルなプログラミング言語で、初心者でもわかりやすいです。 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:



{{#invoke:}}のコールは別の環境で実行されます。 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 Extension:Scribunto/Lua reference manual.

デバッグ コンソール

関連項目: 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 スクリプトエラー messages are clickable and will provide more detailed information.

Lua エラー: 内部エラー: インタープリターは終了コード 1 で終了しました。

When using the LuaStandalone engine (this is the default), errors along the lines of "Lua エラー: 内部エラー: インタープリターは終了コード 1 で終了しました。" 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 エラー: 内部エラー: インタープリターは終了コード 2 で終了しました。

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; # バイト単位

Finally, depending on the server configuration, some installations may be helped by adding another LocalSettings.php line

$wgMaxShellMemory = 204800; # KB 単位

Note that all 3 memory limits are given in different units.

Lua エラー: 内部エラー: インタープリターは終了コード 24 で終了しました。

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 エラー: 内部エラー: インタープリターは終了コード 126 で終了しました。

When using the LuaStandalone engine (this is the default), errors along the lines of "Lua エラー: 内部エラー: インタープリターは終了コード 126 で終了しました。" 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.

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. Cのライブラリを改良するか、インストールされているCライブラリ用にコンパイルされたLua 5.1のバージョンを使用する必要があります。 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.

  1. i.e. proc_open is not within the array of disable_functions 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.
