[PATCH] Include support for evaluating julia code

[Pedro Bruel]

[-- Attachment #1.1: Type: text/plain, Size: 200 bytes --]

Hi,

This patch includes ob-julia.el from org-contrib, and a tentative
test-ob-julia.el test file.
This is my first attempt at a patch, so please let me know if there's
anything wrong!

Thanks,
Pedro

Hi Pedro,

Thanks for your patch, it’s great to see the interest in Julia support and it’s
something that I absolutely think should be in org-core 🙂. However, ob-julia.el
was moved into org-contrib because it was not well maintained, and very buggy.
I’m actually currently working on a successor with Nicolò (see the linked repo)
in my free time, and intend to submit that to Org when I feel it is mature
enough. See <https://github.com/nico202/ob-julia/> for more information.

All the best,
Timothy

Hi Timothy,

Thanks for the reply! I am submitting a modded version the of the original
ob-julia.el, where I had fixed the bugs I encountered and updated the
interface with org-mode.
I've been using the version on https://github.com/phrb/ob-julia for a while
now, mainly to write programming classes using julia.

Yours and Nicolò's version seems good though, I think you should submit it
when you consider it ready. In the meantime, what do we do?

Thanks,
Pedro

[Greg Minshall]

Timothy, Pedro,

would it make sense to consider Pedro's patch as being against the one
in org-contrib?  (i'm not sure how such patches work.)

cheers, Greg

We had previous discussions with Pedro on his contribution regarding
ob-julia.el¹, I agreed he could be the maintainer once he signed the
FSF copyright assignment, so I feel an obligation to apply his patch
right now, but I'm sure Pedro, you and Nicolò can work together on 
the improved version.

If needed, Pedro and you can co-maintain ob-julia.el, feel free to
update lisp/ob-julia.el directly.  

I don't know if Nicolò has signed the FSF copyright assignment but
once he does, he can join the party too.

Thanks!

As far as I’m concerned, the more the merrier 😀.

I’ve talked to Nicolò about this, and I don’t think he has yet, but he’s said he
knows what’s needed and it won’t be a problem.

All the best,
Timothy

Dear Pedro,

Thank you!

I'm wondering if 
https://github.com/phrb/ob-julia/blob/master/ob-doc-template.org is up 
to date? By up to date I mean will the examples in the file work with 
the latest ob-julia as in https://github.com/phrb/ob-julia?

Yours sincerely,

Xianwen
