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

[Anil Madhavapeddy]

Having said that, the Issuu branch seems to fail on MacOS X 10.9 (which uses clang).  Needs more investigation...

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.
