Question

I would like to know if there is a better way (that is, less coding) to have the same output as the following code:

# arg = :a, :b, :c

output = args.to_a.flatten.compact.map(&:to_sym)
# => [:a, :b, :c]

I use the above code to parse arguments passed by a method in this way

`method_name(:a, :b, :c)`.

Answer 1

I don’t see any need for to_a, flatten or compact.

You can just do .map(&:to_sym) if you want to convert strings to symbols. If you’re only accepting symbols, just args contains what you want.

def method_name(*args)
   p args.map(&:to_sym)
end

method_name(:a, "b", :c)

Output

[:a, :b, :c]
