# [opam-devel] [Caml-list] [ANN] IOCaml v0.3

Fri Feb 14 09:57:59 GMT 2014

This is great! (CCing opam-devel)

I'd like to resolve the zmq situation, since the current "ocaml-zmq" package in opam-stable has no maintainer, and is pointing to an unstable tarball.

We could add a new zmq package to OPAM that does not clash with "ocaml-zmq" , based off the Issuu branch which appears maintained.  I'm CCing Anders Fugmann for his opinion on this.  After a while, we could remove the ocaml-zmq package if the upstream cannot be contacted.

That should hopefully unblock getting iocaml into OPAM mainline too...

This provides a REPL within a web browser with a nice user interface including markdown based comments/documentation, mathjax formula and the possibility of generating all manner of HTML based output media from your code.  Here are a few features I think are particularly interesting;

Installation of IPython is a touch more involved as you will have to update (using 'pip') some python components [3].  Instructions for Ubuntu 13.10 are on the github page and I have also tested Fedora 20 which was, apart from some slightly different package names, very similar.
