does this work with ipython 3.1.0?

[bobzhang]

I managed to compile it under ocaml 4.02.1 but when I start iocaml, it can not eval any cell

[andrewray]

iocaml uses ipython 1.3 as a base and would need a fair bit of work to update to 3.1.

Not too sure why iocaml isn't working for you - have you tried installing with opam? That's by far the easiest way to get the correct versions of all it's dependencies.

[bobzhang]

would you mind tell me your working version, I tried 0.13,1.2.1, 3.1, none of them seems to work (on Mac OS)

[bobzhang]

btw, there is no python of version 1.3 in pip

Downloading/unpacking ipython==1.3 Could not find a version that satisfies the requirement ipython==1.3 (from versions: 2.0.0, 2.1.0, 2.2.0, 2.3.0, 2.3.1, 2.4.0, 2.4.1, 3.0.0, 3.1.0, 0.10.1, 0.10.1, 0.10.2, 0.10.2, 0.10, 0.11, 0.11, 0.12.1, 0.12.1, 0.12, 0.12, 0.13.1, 0.13.1, 0.13.2, 0.13.2, 0.13, 0.13, 1.0.0, 1.0.0, 1.1.0, 1.1.0, 1.2.0, 1.2.0, 1.2.1, 1.2.1, 2.0.0, 2.0.0, 2.1.0, 2.1.0, 2.2.0, 2.2.0, 2.3.0, 2.3.0, 2.3.1, 2.3.1, 2.4.0, 2.4.0, 2.4.1, 2.4.1, 3.0.0, 3.0.0, 3.1.0, 3.1.0)

I think the version was actually 1.1 - sorry for the confusion. That being said, you do not need to install ipython itself.

Can you confirm that you are installing iocaml with opam on macosx? Also, what version of websocket do you have?

$ opam show websocket
             package: websocket
             version: 0.9.3
          repository: default
        upstream-url: https://github.com/vbmithr/ocaml-websocket/archive/0.9.3.tar.gz
       upstream-kind: http
   upstream-checksum: b4515352a346371bebf45c05a6269c22
                tags: org:mirage, org:xapi-project
             depends: lwt >= 2.4.8 & tls >= 0.4 & cohttp >= 0.14.0 & ocplib-endian >= 0.8
  installed-versions: 0.8.1 [4.02.0 4.01.0 4.00.1], 0.9.3 [4.02.1]
  available-versions: 0.6, 0.7, 0.8, 0.8.1, 0.9.1, 0.9.2, 0.9.3
         description: Websocket library

There was a problem on osx with websocket <0.9.2.

[bobzhang]

it works now, given that is possible to generate a single static html file, this is really cool that every open source library should be providing an iocaml note-book page for trying its libraries.

That said, I noticed that the dependency is huge, which is quite fragile and close to impossible to install in a closed environment(you don't have a package manager), for me, the user, I think the most fascinating part of iocaml is that it could generate static notebook(using js_of_ocaml)

I think if I only care about static webpages, there should be a way to get rid of dependency on ipython, if so, I would be very interested, thanks -- Hongbo

The links at the top of the page here should help; http://andrewray.github.io/iocamljs

In particular http://andrewray.github.io/iocamljs/creating_static_sites - I think this is what you want.

It seems that the communication between IOCaml and IPython Notebook 3.2.0 failed. Here is the log:

Any help is welcome, Denis Pinsard

[dpinsard]

Great news ! In the file Ipython_json.atd I have deleted the line 43: user_variables : dyn;

... and it works !!

with andrewray/iocaml#36 Jupyter should now be supported once iocaml-kernel is installed with opam. Please see https://github.com/andrewray/iocaml/wiki/jupyter for more info on the testing done with Jupyter.
