This talk delves into the common design principles and +philosophies that unite these powerful tools, focusing on their shared +emphasis +on extensibility, customization, and interactive development. I'll explore +how +both Julia and Emacs empower users to tailor their experience through +powerful +metaprogramming and a rich ecosystem of extensions. I'll discuss the +REPL-driven workflows that foster exploration and experimentation in both +environments. Furthermore, I'll examine how their active and passionate +communities drive innovation. + + +# Discussion + +## Questions and answers + +- Q: As someone who uses Julia, Emacs and Julia *in* Emacs, I feel + like Julia's integration with Emacs is lacking. I haven't found + any way to debug Julia code that works as well as edebug for elisp, + SLY/SLIME for common lisp, or gdb for many other languages (with gud + or realgud). Both Debugger.jl and Infiltrator.jl are difficult to + use interactively. Do you have any suggestions for interactive + debugging of Julia code in Emacs? (Adding to my question: Do other + editors do a better job of interactive Julia debugging?) + - A: GB: Debbuger.jl and Infiltrator.jl are the main debugging + tools available in Julia at the moment. Both of them are not + great (yet) and can use some work. Debugger is going to see + major performance improvements in future releases thanks to work + in the core language. Unfortunately, I don't see anything + better for interactive debugging that is avilable now or in the + near future. Most of the julia community is clustered around VS + code, but the situation is not better +- Q: Can you call out something that Julia has that Emacs does not, and + which could benefit Emacs? + - A: GB: The Julia community is active and more tightly knit than + other communities (e.g., the Python one), JuliaCon is an + in-person event that brings people together. Emacs is also doing + great in this. +- Q: Is there a way to use lisp syntax with Julia, like hy for python + or lisp flavoured erlang? + - A: Julia used to have a femtolisp interpreter built-into its + REPL. + - A: GB: I am not aware, but it might be possible to write a + package to do that. +- Q: Have you tried the Julia Snail package for Emacs? It tries to be + like SLY/SLIME for Common Lisp. + - A: GB: Yes, but I settled on julia-repl (with vterm). I didn't + test julia-snail too much because I found julia-repl easier to + setup and use the way I wished. +- Q: Along the same lines as question 1 \-- is there a data inspector + for a Julia REPL available that you can use in Emacs? + - A: good mode, other good tooling; room for improvement in this + area + - A: GB: No, I don't think anything of that sort is available +- Q: Have you tried literate programming Julia (using Org babel or + some other means) in Emacs? + - A: Literate programming in Julia: Pluto (Jupyter-style, in the + browser), emacs-jupyter (in Emacs) + +## Notes + +- Great, now I wanna learn Julia\... :-) + - Highly recommend it. Especially if you do any sort + of scientific computing. It's an amazing language +- Lots of things to like. Perhaps the most Dylan-like modern + language? +- Got me interested in Julia, great talk +- Sooooo emacs written in julia? +- Amazing, thank you +- M-x clap +- Great talk \[13:10\] +- Thank you for the talk! \\o/ +- Thank you! +- I've been so happy ditching python for julia for all + my scientific research needs :) +- Some of these features, like the interactivity and the decompiler + reminds of Common Lisp +- One of Julia's best features (multiple dispatch) was inspired by + Common Lisp's defgeneric/defmethod. + - I would also add that Julia takes the idea further than Common + Lisp ever did, because you can't opt-out of being generic in + Julia, so it's everywhere and used pervasively. + - In Common Lisp, you had to opt-in, so it wasn't as apparent how + powerful this way of organizing code could be. +- Got me interested in Julia, great talk +- Sooooo emacs written in julia? +- akirakyle: First Guile Scheme (re: Robin's talk, next), + then Julia! ;-) +- Yes ;) +- So julia is like using CLOS everywhere? +- Sort of, but with the llvm runnig full optimized + native code generation for every argument type a function is called + with +- also julia \--lisp is built in! +- emacs-jupyter works with julia quite well btw +- org-babel also works well +- def looking forward to the julia talk +- It would be great to integrate pluto with emacs, but currently very hard to figure out best way to do so +- That would be interesting for sure +- Pluto.run(auto_reload_from_file=true) is the best right now + - Problem is pluto is very tied to browser + - I dislike leaving emacs for things + - But Pluto is a great tool + - Same, I suppose one could alternatively say the problem is emacs can't be very easily tied to the browser + - As opposed to vscode where such integrations are easier + - Although, on the other hand, I am happy emacs isn't tied to a browser + - It's better in general + - Yes it shouldn't be tied to a browser, but it also would be very helpful for emacs to have better access to rendering content that requires a dom/js environment in an emacs window + + +[[!inline pages="internal(2024/info/julia-after)" raw="yes"]] + +[[!inline pages="internal(2024/info/julia-nav)" raw="yes"]] + + |
