bit-level binaries

Waldemar Rachwal
It was mentioned a few months ago (I missed the thread) that a
bit-level binaries (augmented perhaps by binary comprehensions) might
come with a next release. I guess such a big feature should come with
a major release, but when it could happen then (I haven't figured out
the cycle of B-0's)?

(I admit SMP is very cool these days, but the slides from '05 EUC
http://www.erlang.se/euc/05/1640PerKostis.pdf still impress me a lot).

Regards,
WR.

I believe that bit-level binaries were introduced in R11B-3 with shell
support in R11B-4. From my notes it requires some compiler directives:

-compile([binary_comprehension, bitlevel_binaries]).

I haven't tried it yet...

Hi,

I can confirm that bitlevel binaries do indeed work on R11B-4 (haven't
tried any other release). As Bob said, you need to compile using the
bitlevel_binaries option.

Cheers,
Francesco

Bit-level binaries are an unoffical feature for now. Use them at your
own risk. We plan to support them fully in R12B.
