Module pl.strict

Checks uses of undeclared global variables.

All global variables must be 'declared' through a regular assignment (even assigning nil will do) in a main chunk before being used anywhere or assigned to inside a function. Existing metatables' __newindex and __index metamethods are respected.

You can set any table to have strict behaviour using `strict.module`

Functions

module (name, mod, predeclared) make an existing table strict.
