remove_nil_declaration

This rule removes trailing nil values in local assignments. Additionally, it will trim unnecessary expressions in assignments when they do not cause any side-effects.

Examples

local var = nil

local var 

local a, b, c = 1, nil, nil

local a, b,c = 1

local a, b = nil, call()

local b ,a=(call())

local var = call(), otherValue, true

local var = call()

local var = nil

local var 

local a, b, c = 1, nil, nil

local a, b,c = 1

local a, b = nil, call()

local b ,a=(call())

local var = call(), otherValue, true

local var = call()
