We are proud to announce the first public release of
core, Jane Street’s own
alternative to OCaml’s standard library. We use this library as the base for our
own development, and we hope people on the outside will find some use for it as
well. People should be warned that
core is still in flux: there are interfaces that we have plans to change, so
if you’re not willing to come along for the ride, you shouldn’t use it. Also, be
warned that conformance with the OCaml standard library is not a goal, and we
have already deviated from it in a number of ways. It’s also worth noting that
we have only used and tested this library on x86 and x86-64 on Linux, and we
make no claims about other platforms.
You can find the
library here, along with
three other libraries that you will need to use along with it:
bin-prot. These three libraries provide macros for generating
functions for serializing and deserializing types.
sexplib uses a
human-readable s-expression format, and
bin-prot uses a high-performance
binary protocol, and
type-conv is the common base of the other two libraries.
This is also the first public release of
bin-prot, and like
library can be used independently of
(Update: as was noted by some commentors, the packages ounit and res are also required to build core.)
If you have any comments or patches, we’d love to hear about it. The blog is a great place for comments, and patches should be sent to firstname.lastname@example.org.
