Neovim Config

Tip

This is a neovim 0.12 setup, the previous <0.12 version is at the https://github.com/onjin/nvim/tree/0.11. To switch previous main into the newest run:

$ git reset --hard origin/main

Small personal Neovim setup built around native vim.pack, LSP, fast search, and simple file navigation.

Requirements

• Neovim with vim.pack
• git
• rg
• formatters you want to use: stylua, prettier, black, air
• optional LSP tools: lua-language-server, bash-language-server, uvx ty, uvx ruff

Quickstart

Single-file init_compact.lua

You can use the generated single-file config without cloning the whole repo.

Save it as your main config:

curl -fsSL https://raw.githubusercontent.com/onjin/nvim/main/init_compact.lua -o ~/.config/nvim/init.lua

Or run Neovim directly with it from any path:

curl -fsSL https://raw.githubusercontent.com/onjin/nvim/main/init_compact.lua -o /tmp/init_compact.lua
nvim -u /tmp/init_compact.lua

Run directly with Nix

Run this config without cloning the repo or writing it into ~/.config/nvim:

nix run github:onjin/nvim

By default this launcher uses its own isolated base directory at ~/.local/share/onjin-nvim. That means it writes to:

• ~/.local/share/onjin-nvim/config
• ~/.local/share/onjin-nvim/data
• ~/.local/share/onjin-nvim/state
• ~/.local/share/onjin-nvim/cache
• ~/.local/share/onjin-nvim/tree-sitter-parsers

This also keeps the tree-sitter CLI config under the same isolated root, so it does not depend on ~/.config/tree-sitter/config.json.

To use a different base directory, override it explicitly:

ONJIN_NVIM_HOME=/tmp/onjin-nvim nix run github:onjin/nvim

Install

Clone this repo to:

~/.config/nvim

Then start Neovim. Plugins are declared in init.lua and lua/plugins/*.lua.

To generate a self-contained single-file version of this config, run:

./compact.sh

This creates init_compact.lua, which bundles local modules from lua/ and runtime files such as plugin/ and ftplugin/.

Daily Use

• , is the leader key
• - opens the file explorer (oil.nvim)
• <leader>s - prefix for file search, i.e.:
  • <leader>sf search files
  • <leader>sg live grep in git-tracked files
  • <leader>sG live grep with rg
• <leader>f - prefix for finders, i.e.:
  • <leader>fk - find keymaps
• <leader>t - prefix for toggles, i.e.:
  • <leader>ta - toggle vim.opt.autocomplete; default off just use <ctrl-x><ctrl-o> and friends
  • <leader>tb - toggle light/dark theme
• <leader>g - prefix Git/GH CLI pickers, i.e.:
  • <leader>gi - gh issue list
  • <leader>gp - gh pr list
  • <leader>gs - git status
• glf format the current buffer
• grd jump to definition
• <leader>? shows buffer-local keymaps
• in insert mode:
  • <C-x><C-u> opens generated values completion (uuid1-7, ulid, date/time)
  • <C-g>k opens generated values menu (vim.ui.select)
  • <C-x>1..7 inserts uuid1..uuid7
  • <C-x>u inserts ulid
  • <C-x>d inserts date (YYYY-MM-DD)
  • <C-x>t inserts datetime (YYYY-MM-DD HH:MM:SS)
  • <C-x>i inserts ISO datetime (YYYY-MM-DDTHH:MM:SS+TZ:TZ)
• TSInsall [python] - to install required tree sitter queries for certain languages

Included

• snacks.nvim for pickers and toggles
• quicker.nvim for editable quickfix window as buffer
• oil.nvim for directory editing as buffer
• native LSP with Lua, Bash, Java, and Python support
• conform.nvim for formatting
• Treesitter, Catppuccin, mini status/tab line, and todo highlighting

Test in isolation

Run the compact config with isolated XDG_* directories:

./test-compact.sh

Run the local flake the same way:

./test-flake.sh

Both scripts avoid loading ~/.config/nvim. On the first run they may still need network access, because vim.pack installs plugins into isolated XDG_DATA_HOME.
