Python-mode VS vim-slime

As for the Vim auto complete plug-in to use. The biggest (and rather quite bloated provider) are coc and youcompleteme. Vim had countless other completion provider plugins over the years, I lost track of which ones are still good to use and which ones should already be superseded by better techs, but one I personally use python-mode, which uses rope and vim-lsp which supports pylsp.

python-mode plugin works well as an IDE-like solution: https://github.com/python-mode/python-mode

If you're happy with a plugin, pymode (https://github.com/python-mode/python-mode) is worth a look. Map running to r (or whatever works for you) makes running easy. End result is IDE-like.

If you want a quick start to building Vim based IDE for Python, I recommend python-mode. It gives you most of the things you're going to need in one plugin, there are often better implementations of some of its features in other more specialised plugins, but if you don't have time to research and learn to integrate a lot of different plugins, it's a great base to start from. Over time as you learn how you prefer to work and found specialised plugins that suits your workflow better, you can disable many of its features and replace them with more specialised plugins.

I also highly recommend python-mode for Python refactoring using python-rope. It supports variable/function/class renaming, extract method/local variable, variable/method inlining, adding/removing/rearranging parameters from method signature, removing unused and duplicate imports, and many other useful code transformations.

However, adding all these things by hand takes time. I only know python so that's what im using vim for, and i tried out pymode, but that's way too many features introduced at once. For this reason I've also avoided using others configurations.

Eg for python (there are several others) https://github.com/python-mode/python-mode

There is a plugin called python-mode. This adds syntax highlighting and many other features to your vim.

Update that tool to work with Python. For example, Python-Mode.

you can have a REPL in nvim/vim/tmux/screen/another terminal/or any other window , and send regions from your vim buffer to that repl

For vim users, check out vim-slime[1]. It's really changed my workflow! It can work for any language that uses a REPL, including bash/shell. Combined with tmux, it is an amazing and (in hindsight) obvious tool. I honestly can't imagine myself going back to not having it now.

For splitting the terminal you could try either toggleterm or tmux. If you want to send things from one tmux pane to another, then you can use slime. For a toggle-able filetree, you can use nvim tree.

I use vim-slime. It works really well in tmux. https://github.com/jpalardy/vim-slime. Just blocks of code as cells

This is yet another plugin to capture text from the current buffer and send it to a tmux pane. I was using https://github.com/jpalardy/vim-slime previously, and wished I could just set sensible defaults for where to send text. Also, I wanted to create my first Neovim plugin! I have to say, after writing a bit of Vimscript in the past, the Neovim Lua API makes me a much happier camper.

I use slime (which sends code to tmux panes), tmux (of course) and ipython for this. For example, the code I sent to ipython was with a simple keybinding ...

If I understand correctly, what you need is a combination of vim, tmux, ipython and vim-slime.

REPL??? Do you have a very-easy-to-use way of running and testing your code? From vim-slime to nvim sniprun to autocommands with the built in terminal, to an external repl like ptpython (for python obviously). iron.nvim and conjure are two other neovim repl plugins. There are many ways of running the code that you're working on, and having something that makes this really easy for you is pretty essential. (sometimes I use inotifytools on linux to literally just run the script every time I save it.)

For the record/list, there's also: - https://github.com/hkupty/iron.nvim and - https://github.com/jpalardy/vim-slime

However, if you're coding in an interpreted language like python, R, bash, etc., then there is one plugin which you are likely to find helpful. That's vim-slime.
