How can i split a binary in erlang

Question

What I want is, I think, relatively simple:

> Bin = <<\"Hello.world.howdy?\">>.
> split(Bin, \".\").
[<<\"Hello\">>, <<\"         


        

Answer 1

The module binary from EEP31 (and EEP9) was added in Erts-5.8 (see OTP-8217):

1> Bin = <<"Hello.world.howdy?">>.
<<"Hello.world.howdy?">>
2> binary:split(Bin, <<".">>, [global]).
[<<"Hello">>,<<"world">>,<<"howdy?">>]
