[image] Editor-independent parts of Juno Reading some Juno backend code it looks like it is interfacing with Julia via a socket, I wonder if I could just implement the Emacs frontend for that (currently just running a terminal inside Emacs). Not to pull this thread too far off-topic, but for a…

[image] stevengj: Not sure what you mean, precisely, but the Jupyter protocol is pretty extensible. You can add new message types and new data to existing messages without disrupting existing backends. New message types is definitely part of it (and good to see that it’s supported). The othe…

Ok, that’s what I suspected. When I said they should be “client concerns”, what I meant is that ideally the server only concerns itself with evaluation, not representation. i.e. A graphical IDE may have a very different idea of how to represent a Julia object returned from an evaluation than a textu…

Not having read the thread in full detail I’m not sure this is helpful, but is this what you are looking for? remote_ikernel

[image] jballanc: what I meant is that ideally the server only concerns itself with evaluation, not representation. i.e. A graphical IDE may have a very different idea of how to represent a Julia object returned from an evaluation than a textual console. The way the Jupyter protocol works is …

[image] stevengj: Usually, non-image representations will be small, so there is no problem in sending several textual representations along with perhaps one image representation. Hmm…I would worry that image, or even say video, representations could get large and cause network issues. Would s…

Did this go anywhere in the end? I hacked something together for my own use: https://github.com/jamii/exo/blob/master/Emacs.jl https://github.com/jamii/exo/blob/master/init.el#L180-L361 It can handle scoped eval, autocomplete and docs like Juno does (the addition of Base.include_callbacks in Jul…

This looks really interesting. I am travelling now, but plan to read this and give feedback next week.

I also have similar stuff for GtkIDE, although it’s Julia to Julia communication and it’s not very good. One thing that I need is the ability for the eval part to return a Julia object (like a plot) and serialize it back to the client. Note that the evaluation also need to be interruptible.

@Tamas_Papp Btw this works ok alongside julia-repl. I run Emacs.start_server() from julia-repl and do eval with my code, but still get the clickable file locations from julia-repl. I haven’t figured out a way to do those outside of emacs yet. Another thing I’m stuck on is inserting text into the re…

[image] jonathanBieler: Note that the evaluation also need to be interruptible. Yeah, that’s another reason to want to reuse the existing repl infrastructure. I wonder if it’s possible to get the StreamREPL in the stdlib working again? Then the frontend just needs to handle networking and fig…
