Extension: Scribunto

Overview
Description:	provides a framework for embedding scripting languages

in MediaWiki. Currently the only supported scripting language is Lua.

Requirements

PCRE version compatibility

PCRE 8.33 or later is recommended. You can see the version of PCRE used by PHP by viewing a phpinfo() web page, or from the command line with the command php -i | grep 'PCRE'.

• Scribunto will not work with versions of PCRE lower than 8.10.
• PCRE 8.31 has bugs with JIT pattern studying that breaks various patterns when used with HHVM.
• PCRE 8.32 has a bug that will cause it to reject certain non-character codepoints, which will cause errors in the mw.html module.

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 pcntl

Since Scribunto for MediaWiki 1.25, your PHP server also needs to have pcntl enabled (only works with Unix/Linux platforms) if you want to use "LuaStandAlone" (i.e. running in a separate child process). Under Windows, Scribunto will run Lua only as "LuaSandbox" (within the same PHP thread as the thread used by MediaWiki to run this Scribunto extension, but within the sandboxing PHP environment configured by Scribunto).

PHP mbstring extension

PHP needs to have the mbstring extension enabled.

To see if it installed on your server, you can check if it is enabled by running the command php -m on the server. If the string mbstring is present in the output, the extension is enabled.

PCRE version compatibility

PCRE 8.33 or later is recommended. You can see the version of PCRE used by PHP by viewing a phpinfo() web page, or from the command line with the command php -i | grep 'PCRE'.

• Scribunto will not work with versions of PCRE lower than 8.10.
• PCRE 8.31 has bugs with JIT pattern studying that breaks various patterns when used with HHVM.
• PCRE 8.32 has a bug that will cause it to reject certain non-character codepoints, which will cause errors in the mw.html module.

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.
