sideways.vim VS splitjoin.vim

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.

My splitjoin plugin handles your examples, in case you're open to non-LSP, non-treesitter solutions: https://github.com/andrewradev/splitjoin.vim

To avoid the practical issues with master/main, a simple solution is to mirror branches in a github action. I had to fork the action itself to fix an issue, but yeah, it works fine.

Yes, sorry, should have done that the first time I encountered the bug. I rediscovered the bug and I opened a new issue.

I quite like https://github.com/AndrewRadev/splitjoin.vim . There are defaults for some filetypes and you can add "recipes" for whatever you want.

splitjoin to alternate between abbreviated and expansive syntaxes for hashes, arrays, method calls...

To clarify a bit, "a regex approach" doesn't mean s// :). For example, I've got a few mini-parsers for specific cases like rust structs or ruby methods and hashes that handle nesting and more complex structures. Vim's built-in search functions also allow checking the syntax tree, which is how vim-ruby implements a few basic text objects, too. I feel like there's a common misconception that all of Vim is just dumb regex-matching, while regexes are just one of the tools available.

I personally use this plugin: https://github.com/AndrewRadev/splitjoin.vim I usually forget I have it installed, but when I remember, it always does what in want in all the languages I use
