AdventOfCode2020 VS Nvim-R

> At the end of the day, you quit your environment and shut down. How do you ensure your interactive work is not lost and the environment is still what you expect it to be when you start again the next day. How would you compile such a program?

Modern Smalltalks have solved this problem. Smalltalk has the concept of Packages just like Java, and as you go along building your environment, even though you are modifying the Smalltalk image, you can export these packages to plain-text files, and put them in Git, just like any other language. The environment itself supports Git integration (called Iceberg in Pharo).

> Also, if significant parts of the source code are written inside the REPL, wouldn't the lack of modern IDE features be a hassle? No syntax highlighting, no code completion, no code inspections etc. Or are there tools that offer those?

The command-line REPLs that other languages have are NOT what you get in Smalltalk. I believe the author means the entire interactive environment, and the "style" of development is REPL, not the actual UI. The Smalltalk "IDE" is just as powerful as any other IDE, including code completion, automatic generation of certain getters/setters, renaming methods/classes, finding uses, jumping to declarations and even refactoring within methods. The difference between a normal IDE for Java is that this "IDE" is pervasively available, including in breakloops and the debugger. Since the system is live, there is no separate notion of debugging, the debugger is always there, and you can use all the editor IDE features when stopped in a debugger. You no longer have to deal with a crippled debugging environment way different from your authoring environment. It truly is mind-blowing!

I highly recommend giving Pharo Smalltalk a spin (by following their MOOC or similar). This video is also worth a watch - https://www.youtube.com/watch/baxtyeFVn3w

I did most of this year's Advent Of Code in Smalltalk and saved it in Git just like any other language. Someone else can then import it into their image. https://github.com/nikhilm/AdventOfCode2020.

Note that the source code looks very verbose, but you never actually interact with the source like that. The source is just a serialization. Your actual environment only ever shows you UI elements and entire IDE windows describing your classes and individual methods.

The only thing I miss in Pharo is that it doesn't have Vim keybindings :)

If you do a lot of R coding, then a package more specific to R, and more fully featured is Nvim-R.

The whole reason I ended up going this route was also sort of data-science related: there’s a really spectacular R plugin for Vim, which I wanted to recapitulate as best I could when using python: https://github.com/jalvesaq/Nvim-R

I am slowly getting into using neovim. I am now trying to setup my R programming environment. I have successfully installed Nvim-R with Packer (https://github.com/jalvesaq/Nvim-R). Now, I would like to use the radian console (https://github.com/randy3k/radian/blob/master/README.md#nvim-r-support). In the documentation, it is said to put this in the config file:

But just wondering if people have tried using it with the Nvim-R plugin? I'm not sure it is worth the effort for me looking through the steps needed. Also, do I need to switch my init.vim/vimrc to lua? Perspectives appreciated!

However, there doesn't seem to be much available support yet for Quarto editing. The only plugin I could find is limited to syntax highlighting. To my knowledge, Quarto also isn't a built-in filetype yet. I've worked around this by manually creating a filetype and using R Markdown syntax highlighting with the Nvim-R plugin, which lets me send R code in chunks to a REPL and see results while I edit. Nvim-R also supports evaluation of Python code chunks using an R package that evaluates Python code, but that's not an ideal solution for editing a Python-only file.

looking for a neovim plugin that's similar to Nvim-R, but for python.

For that reason, I want to use Nvim-R in combination with ncm-R. I get the completion to work if I use it manually with Ctrl+x Ctrl+o, but it does not start automatically. My init.vim file looks like this:

I use Nvim-R. It took a bit of time to learn the key bindings, but the documentation is pretty clear.

If you want to go in a very different direction, you can try vim (or neovim) with nvim-r. For a variety of reasons, that’s what I tend to use.

nvim + Nvim-R user here as well.
