This extension is designed to emulate and extend the function of the $wgNonincludableNamespaces configuration variable, which was introduced in MediaWiki v1.10.0.

• In versions of MW < 1.10.0, it emulates the functionality of the config variable, along with the additional functionality detailed below.
• In versions of MW >= 1.10.0, there is already code to handle this variable correctly, but the extension adds a couple of configuration short-cuts that make things a bit more flexible.

[edit] Usage

This extension adds the full functionality of $wgNonincludableNamespaces, plus the enhancements below, to versions of MediaWiki < 1.10.0. From 1.10.0 upwards, $wgNonincludableNamespaces exists natively in the software, in which case the extension simply implements the additional features.

[edit] Emulated features

• If $wgNonincludableNamespaces is not set, then all transclusion is allowed.
• If $wgNonincludableNamespaces is an array then transclusion is not allowed for any namespaces included in the array. Elements must be numeric namespace ids.

[edit] Additional features

• If $wgNonincludableNamespaces is not an array then it is evaluated as a boolean with the following results:
  • If True then no transclusion is allowed, except from the template namespace.
  • If False then no transclusion is allowed at all.

[edit] Developers

The extension defines the constant NIN_Installed when it is loaded, so extension developers can check whether the $wgNonincludableNamespaces variable is supported, either via MW or this extension, by using the following code:

if ( version_compare($wgVersion, '1.10.0', '>=') || NIN_Installed ) {
        // Installed
}
