neovim-config

Overview

This is the Neovim setup I use for everything: Rust, C and C++, TypeScript, Java, Nix, Lua and Markdown notes. The repo dates back to 2023 and credits Josean Martinez's config tutorials. It's a small Lua config on lazy.nvim. init.lua loads the editor settings, the plugin manager and global keymaps, and each plugin lives in its own spec file under lua/plugins/.

Language servers

The language-server setup is the most distinctive part. Rather than relying on Mason to install language servers, the config keeps a table that maps each server to the binary it needs, and at startup it enables only the servers whose binary is on PATH:

for server, binary in pairs(LSP_BINARIES) do
	if vim.fn.executable(binary) == 1 then
		local config = LSP_SERVERS[server] or {}
		vim.lsp.config(server, {
			settings = config.settings or {},
			init_options = config.init_options or {},
		})
		vim.lsp.enable(server)
	end
end

That fits NixOS. My nixos-config installs the servers and formatters through home-manager but leaves the Neovim config alone. The same config also works on a machine with half the toolchains, without errors about missing servers. Per-server settings keep 4-space formatting consistent across nil (with nixfmt), lua_ls, ts_ls and clangd.

Some languages get dedicated plugins: rustaceanvim for Rust, nvim-jdtls for Java (with the Lombok agent), and VimTeX for LaTeX.

Formatting and linting

• conform.nvim runs Prettier (with tabs), stylua, black and isort, and clang-format with an LLVM-based style that uses tabs. Format-on-save is wired up but off by default. <leader>ft formats on demand.
• nvim-lint runs eslint_d for JS/TS/Svelte and pylint for Python on enter, save and leaving insert mode.

Navigation

oil.nvim replaces netrw as the file explorer, so directories are editable buffers. Telescope handles search, and Harpoon marks the few files I'm bouncing between (<leader>hx to mark, <leader>hn/<leader>hp to cycle). vim-tmux-navigator moves across Neovim splits and tmux panes with the same keys, and global-note keeps one scratch note on <leader>`.

AI tools

claudecode.nvim is bound under <leader>a. It toggles, resumes or continues a Claude Code session, sends a selection or the current buffer, and accepts or rejects proposed diffs. opencode.nvim is bound under <leader>o and points at a local Ollama model (qwen2.5-coder:32b), so I can use an assistant offline.

Markdown

Markdown buffers turn on soft wrap and line breaks and map j/k to gj/gk. peek.nvim opens a live preview in the browser.
