This module provides a Lua interface for the parser functions provided by Extension:Variables.

Usage

Function names are identical to the parser function names.

Variables.vardefineecho

Returns the value as it was stored (as a string). Should only be used to verify the stored value, not for inline declarations.

Differences

• Returns nil instead of empty strings (use p.varexists() to check for variables holding an empty string).
• varexists() returns a boolean instead of 1 or nil.
