lua-vs-vimscript VS guess-indent.nvim

Here’s a benchmark from an internet stranger: https://github.com/henriquehbr/lua-vs-vimscript

I don't know the exact reason for this, but if I had to guess it probably comes down to the fact that in Neovim Lua is significantly faster than vimscript (with vim9 the performance gap narrowed, but afaik there is no intention to port vim9script to neovim), and that vim-sleuth heavily relies on Regex.

I decided to create a basic repository automating the environment for running this benchmark, you can find it on GitHub

Instead of setting setlocal tabstop=2 shiftwidth=2 softtabstop=2 in each file, I recommend using the following plugin: guess-indent.nvim. It provides automatic indentation style detection for Neovim, which can simplify the process.

The fantastic nmac427/guess-indent.nvim package is used to automatically detect the indentation scheme when a file is opened.

In addition to editorconfig, which other comments have mentioned, there are also plugins that can set your indentation options based on the presence of tabs or spaces in the files you have open. I like guess-indent.nvim.

I use a combination of guess-indent.nvim and :h listchars. Here's how I use them together in my config.

If you want to have a different indentation based on the current file context, take a look at this plugin: https://github.com/NMAC427/guess-indent.nvim

I'd add guess-indent to that list as well, if you're working on a project that doesn't have a set standard on indentation.

I use this plugin guess-indent.nvim
