sideways.vim VS plenary.nvim

There's a number of plugins for an "argument" text object (mine is sideways), but if you're just looking for a simple "change between commas", here's a great SO answer that explains how to create a mapping like that for yourself in two lines: https://stackoverflow.com/a/44109750/853920

sideways.vim: move arguments left and right (I know this is nowadays done with tree sitter, but there isn't a ts grammar for everything so far)

Yeah, I use sideways.vim and vim-exchange. (Not entirely sure which solves what OP is asking about.)

I use vim-sideways for this. If vim-swap doesn't work out, give it a shot!

For the second case Sideways has SidewaysArgumentAppendLast. I mapped it to A (shouldn't conflict with other mappings).

For argument lists, check out sideways.vim which is smart enough to shift arguments around instead of only selecting them.

But there's also another "classic" plugin just for this use case: https://github.com/AndrewRadev/sideways.vim I've never used it though, so can't comment on its use, but it looks pretty good.

Also not a native solution, but I've been using sideways.vim for a while. I have space as my leader and use leader-L and leader-R.

we can create a function to open a pop up menu using plenary.popup like this, you need to install neovim plenary if you don't already have it https://github.com/nvim-lua/plenary.nvim

If you are really interested in doing this yourself with loop, you should take a look at either plenary.job or netman.shell (I made the latter) as both are very well documented.

I feel this :( That said, alot of plugins rely on plenary.nvim. Its up to you if you determine this is "non-essential" or not. It will almost certainly be available for you to use already.

The big reason I ask is that reaching out to an external python shell to run commands (disregard the fact that its python running) is going to be much slower than using the in built lua JIT interpreter. Additionally, plenary has a built in curl function so you don't have to "reinvent the wheel".

There is also test harness in nvim-lua/plenary.nvim with a slightly different design, but still usable of course.

I am simply using busted or more specifically vusted which is a wrapper around busted for Neovim. It should be quite straightforward to learn the basics, I would say you mostly need to know these functions: describe, it (these are used to structure your test cases) and assert.are_same (to check for table equality). Some people are also using plenary which is also based on busted.

It's based on nvim-lua-plugin-template, but uses Nix flakes to run plenary.nvim tests.
