indent-o-matic VS vim-swap

there is indent-o-matic

I use indent-o-matic, along with these defaults:

I use https://github.com/Darazaki/indent-o-matic currently and set it with a keymap when that fails.

I do use a plugin to match the indentation of existing files (indent-o-matic), and that overrides my own indentation preferences; matching the indentation style of an existing codebase is more important than my own preferences or a language style guide. But if I'm starting a new project I stick to tabs for accessibility (unless it would cause whitespace syntax problems).

How does it compare to IndentOMatic?

Only one I use that hasn't been mentioned is a standalone vim-swap replacement. The existing ones all need treesitter (that I know of)

vim-swap provides an easy way to swap delimited items. It also provides textobjects targeting them, so deleting an argument becomes as easy as da,

I use this feature right now, and it simplifies a lot. I use t to open tabmode so I can create or destroy tabs easily. b, which I use more often, opens bufmode so I can switch the buffer in the current window, or delete it while preserving my layout. gs allows me to swap delimited items using hjkl. w is for visually switching between open splits. Etc etc

I recommend machakann/vim-swap. This plugin provides the way to swap function parameters, and text-objects that can be used to select parameters:

I've been using vim-swap for a while and it's simple enough: when on top of a delimited argument, you can hit g> or g< to swap right or left, respectively.
