Erlang Binary Split -

-

i need split binary so

<<"one|two|three|four|five">>

into 

[<<"one">>,<<"two">>,<<"three">>,<<"four">>,<<"five">>]

i'm there

binary:split(<<"one|two|three|four|five">>, <<"|">>, []).

but need make scope global split entire binary , not first item. answer staring me in face here http://www.erlang.org/doc/man/binary.html#split-3 i'm having trouble working out documentation how specify scope global?

as usual, blindingly obvious once have worked out:

binary:split(<<"one|two|three|four|five">>, <<"|">>, [global]).
