remove_unused_variable

Added in 0.13.0

This rule removes unused variables from code. It also removes unused local function definitions.

Examples

local var1 = true
local var2 = var1

local var = call()

call()

local function fn() print('unused') end

local a, b, c = 1, 2, 3
return a

local a=1
return a

Input	Output
`local var`
`local var1 = true local var2 = var1`
`local var = call()`	`call()`
`local function fn() print('unused') end`
`local a, b, c = 1, 2, 3 return a`	`local a=1 return a`
