Elixir remove nil from list

Enum.filter/2 comes to the rescue:

Enum.filter(list, & !is_nil(&1))

If you are certain there could not be false atoms in the list (the other possible falsey value in Elixir,) the filter might be simplified to:

Enum.filter(list, & &1)

Also (credits to @Dogbert) there is a counterpart function Enum.reject/2 that “returns elements of enumerable for which the function fun returns false or nil.”

Enum.reject(list, &is_nil/1)

this worked for me :

Enum.filter(s, fn x -> if(x != "") do x end end)

Enum.filter(list, fn x -> x != "" end)
