minimal neovim 0.12 config

2026-05-06

With nvim including their own package manager and new config features, I wanted to write a little bit about my new config to reference.

Here is my neovim config directory:

~/.config/nvim $ tree -L 2

init.lua

My init.lua just requires the other lua files, in the /lua directory

require('options')
require('keymaps')
require('autocmds')
require('lsp')

plugins

Neovim 0.12 made it easy to use the built-in package manager pack.

Below is the lua config file for barbar. Dead simple config file.

plugins that i use

barbar - buffers as tabs
blink.cmp - fuzzy find autocompletions
colorizer - live preview of color codes typed
conform - auto format code on save
devicons - icons/glyphs for different filetypes (you can see the lua icon in the bar in the above screenshot)
fzf - fuzzy finder for lua
mason - package manager for lsp servers/formatter/linter
nvterm - easy embedded terminal in neovim (i dont like tmux)
todo-comments - highlights on comments that say NOTE or FIXME or whatever. just a quick visual way to see action area in a file
tokyonight - neovim colorscheme
vim-sleuth - something to do with consistent tab/spaces ? might get rid of this one barely remember the reason

My mason config file:

vim.pack.add({
	{ src = "https://github.com/mason-org/mason.nvim" },
	{ src = "https://github.com/mason-org/mason-lspconfig.nvim" },
	{ src = "https://github.com/WhoIsSethDaniel/mason-tool-installer.nvim" },
})

-- mason core
require("mason").setup({
	ui = {
		icons = {
			package_installed = "✓",
			package_pending = "➜",
			package_uninstalled = "✗",
		},
	},
})

-- mason-lspconfig
require("mason-lspconfig").setup({
	ensure_installed = {
		"rust_analyzer",
		"html",
		"ts_ls",
		"yamlls",
		"lua_ls",
		"basedpyright",
		"bashls",
		"sqruff",
		"stylua",
		"css_variables",
	},
})

-- tool installer
require("mason-tool-installer").setup({
	ensure_installed = {
		"prettierd",
		"stylua",
		"shfmt",
		"ruff",
	},
})

You can install these LSP servers on your system yourself and add them to PATH, but for my use, it's easier to just install npm and pipx, then let mason-lspconfig install the LSP servers that I use.

lsp

To avoid using nvim-lspconfig and having 1 big file with every language server, you can configure lsp settings yourself and separate them into their own files in the /lsp directory.

Examples configs: https://github.com/neovim/nvim-lspconfig/blob/master/doc/configs.md

Here is my basedpyright config:

---@type vim.lsp.Config
return {
	cmd = { "basedpyright-langserver", "--stdio" },
	filetypes = { "python" },
	root_markers = {
		"pyrightconfig.json",
		"pyproject.toml",
		"setup.py",
		"setup.cfg",
		"requirements.txt",
		"Pipfile",
		".git",
	},
	settings = {
		basedpyright = {
			analysis = {
				inlayHints = {
					variableTypes = false,
					callArgumentNames = false,
					functionReturnTypes = false,
				},
				diagnosticMode = "openFilesOnly",
				autoSearchPaths = true,
				useLibraryCodeForTypes = false,
				typeCheckingMode = "standard",
			},
		},
	},
}
