Extension:VariablesLua - MediaWiki

The VariablesLua extension provides support for the Variables extension in Lua modules by the Scribunto extension.

Bugs and Feature Requests: Issues at GitHub

The extension can be loaded in Lua modules by the Scribunto extension like this:

VariablesLua = mw.ext.VariablesLua

Functions are based on the ones provided by the Variables extension, adding some more utility.

VariablesLua.vardefine[edit]

VariablesLua.vardefine( name, value )

Stores the given value under the given name. An empty string is stored if the value is nil.

VariablesLua.vardefineecho[edit]

VariablesLua.vardefineecho( name, value )

Identical to VariablesLua.vardefine, but returns the value after storing it.

VariablesLua.var( name, default )

Retrieve a variable stored under the given name.

VariablesLua.varexists[edit]

VariablesLua.varexists( name )

Check if a variable exists. Returns a boolean value.

VariablesLua.var_final[edit]

VariablesLua.var_final( name, default )

Returns the last value stored (i.e. the last VariablesLua.vardefine or #vardefine in the code). The value can only be returned and not used in the Lua code.

Make sure the Variables extension and Scribunto extension are installed.
Download and place the file(s) in a directory called VariablesLua in your extensions/ folder.
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadExtension( 'VariablesLua' );
```
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
