- negate (func)
-
Takes a predicate function and reverse the value returned. If the function returns true, it'll now return false. If the function returns false, it'll now return true.
Parameters:
- func Your predicate function, a function that only returns true or false. Parameter count doesn't matter, we'll unpack and call it for you.
Returns:
-
negated Your reversed predicate function.
Usage:
local func = require 'luafp/func'.negate function isCow(o) return o == 'cow' end print(isCow('cow')) -- true isNotCowLulz = func.negate(isCow) print(isNotCowLulz('cow')) -- false print(isNotCowLulz('chicken')) -- true
