List of strings to binary and back again
I've stumbled on a quite irritating problem;
I'm trying to ge开发者_JAVA技巧nerate a binary of a string-list and back again. Eg
erlang:binary_to_list(erlang:list_to_binary(["hello", "world"])
This will return "helloworld" and not a list with two different elements. Does anyone have any ideas of how to solve this? One solution might be to encode every element, but there might be a more elegant solution for this?
Yes, you have to encode it somehow. Here's the simplest way to do it by encoding it into Erlang binary term format
erlang:binary_to_term(erlang:term_to_binary(["hello", "world"]))
Strings are merely a list of ints in erlang those the concat done by list_to_binary.
