Re: [Texmacs-dev] TeXmacs and jupyter

[Massimiliano Gubinelli]

Dear Darcy, Miguel

Thanks to both for the suggestions.

I agree with Darcy that we could develop the plugin outside the main  svn tree.

And for the moment  I have no  clear ideas about ensuring the proper runtime environment, some experimentation with the solutions Miguel described is needed.

Anyway  I really think that it is not  difficult to modify jupyter_console to output  TeXmacs’s plugin protocol. I will look at this as soon as  I have some time.

As for Guile 2.0, at the moment I’m trying to look at  the remaining bugs which  are a   bit subtle since they are generated  by the different evaluation strategy wrt 1.8.

I suggest we should develop the jupyter plugin independently. I mean, we should not code under the SVN repo. It is not a good idea to package python binary and dependencies in TeXmacs.

Just like https://github.com/texmacs/TeXmacs.scala , simply start it as a github repo.

And for now, I do think we should focus on upgrading guile to 2.x for GNU TeXmacs. Once we migrate to guile 2.x, we can  make TeXmacs available in Debian/Ubuntu/...

Personally, this is my dev plan: http://forum.texmacs.cn/t/my-development-in-2019-on-gnu-texmacs-sadhen/37

However, I'd like to help if anyone starts to write a jupyter plugin. And I do think the plugin system should be improved.

There are at least four standard ways of ensuring dependencies are met:

1. python package manager (pip) on top of the OS installation. Not nice since installs are OS wide. 

(pip is itself a python package which we can assume is available as long as there is a python distribution installed ( after 3.something it's installed by default, otherwise it's trivial to install) )

2. virtualenv. Per user, local installs in one directory, including specific python binaries, using pip. AFAIK the "venv" module is also included in python installs by default.

3. conda. Same as virtualenv but allowing for other binary dependencies (libraries). miniconda is lightweight and pretty much a standard

4. containerised solutions (docker + first item in this list). Does not apply to our case.

IMO virtualenv is the way to go in TeXmac's case since it is itself a python package and we won't need any 3rd party libraries (non-python). But maybe someone else has another suggestion? I always do the fourth, so I rarely use virtualenv.

I'm afraid I really cannot help out now, I'm sorry :( Maybe in a couple of months..

Dear all,

 I was looking at the jupyter protocol, in view of integrating it with TeXmacs. Instead of reimplementing everything (which seems quite complex) we could try to modify the jupyter console here

https://github.com/jupyter/jupyter_console

to make it output the TeXmacs plugin protocol instead that using standard output, in this way we can call it from TeXmacs and have jupyter kernels at our disposal. This will make available many other systems inside TeXmacs.

It should not be very difficult but I need some help since I’m not very familiar with python. In particular I do not undestand how we should do: surely we want to branch the jupyter console to have our own version adapted to TeXmacs protocol, but in order for it to run it would need to have some other packages available (like the one implementing the jupyter protocol, and some other, like for example pygments, to colorise code). How one can be sure that these are available on the client machine? Is there a standard way  to require packages? Can one assume they are always installed? I have a very poor understanding of Python ecosystems.

Are  you interested in join this effort?

Miguel? Darcy?
