NeoVim as a programming IDE

🏎 🏎 🏎 Need for speed! 🏎 🏎 🏎

This neovim configure file is highly optimized for the impatient. Super lazy loading + After syntax highlight rendering. Render multiple files with treesitter in less than 45ms with ~170 plugins installed (e.g. Open both util.lua(1686 loc) and lsp.lua(1538 loc) from neovim source code in 58.6ms) The setup set all plugins to be lazy loaded and trigger when it needed.

The Packer config locates in branch Packer branch It serves as my personal nvim setup. I am using it as my daily driver. The structure can be messy so it is not a setup for beginner

  • nvim Telescope preview: telescope

  • nvim+kitty + cmp :

    ![vim_ide with


Battery included

About 150 plugins and 14000 lines of lua and vim code.


  • Keymaps : floating windows show all keymaps defined in this repo
  • Jsonfmt: format json file
  • LG: lazygit
  • FZF: fzf
  • Spell: spell check
  • Gram: Grammar check
  • Bd: better bdelete
  • Gd: gitdiff(with fzf and delta)
  • Rg: ripgrep with telescope

Neovim Plugins

There are lots of amazing plugins, I used following plugin a lots

  • Plug -> Dein -> Lua-Packer -> lazy.nvim

    I followed Glepnir https://github.com/glepnir/nvim dotfiles when I start this repo. A.T.M. nvim-cmp as a completion engine with LSP, LSP saga. vim-multi-cursor, telescope. treesitter, lazy load vim-go. So, other than module folder, I could copy/paste everything else from glepnir's configure file, which make my life easier.

  • Telescope + fzf

    One of the best plugin for search anything. I used it to replace fzf, leaderF, leaderP, defx, Ag/Ack/Rg, yank(ring), project management. undolist and many more. Telescope is awesome, only issue is performance.

  • nvim-lsp with navigator.lua

    vim-go and coc add around 200ms time and some of the extensions might crash when I using (but it hard to check which because ~4 node.js services coc forked) Some useful script from TJ, and glepnir

    nvim-tree: file-explorer (lightweight and fast) hrsh7th/nvim-cmp: auto-complete vsnip + luasnips: code snipts(Load snippet from VSCode extension). It is a full featured IDE.

    document symbol

  • ALE -> Efm -> null-ls

Lint and format moved to null-ls.

  • Programming support: Treesitter, nvim-lsp and navigator.lua, for go, go.nvim

  • Debug:

    dlv, nvim-dap

  • Theme, look&feel:

    home cooked Aurora, windline (lua), devicons(lua), blankline(indent), bufferline

  • Color:

    Primary with treesitter from nvim nightly (nvim-lsp and this make it hard for me to turn back to vim), log-highlight, limelight, interestingwords, hexokinase as a replacement for colorizer (display hex and color in highlight)

  • Git:

    fugitive, nvimtree, gitsigns.nvim, diffview.nvim

  • Format:

    tabular, lsp based code formating (or, sometimes prettier), auto-pair

  • Menu and tab:

    • guihua.lua the UI I created for personal use
    • nvim-bufferline.lua: Yes, with lua and neovim only
  • Tools: Toggleterm, scrollview

  • Move and Edit:

    easymotion -> hop&lightspeed, vim-multi-cursor, navigator.lua (better treesitter folding), Sad for complex find and replace


Note: I tested it on Mac and linux, not sure about window

Clone the repo

Link nvim to $HOME/.config/


ls ~/.config/nvim

~/.config/nvim -> /Users/rayx/github/dotfiles/nvim

On windows the config path is C:\Users\your_user_name\AppData\Local\nvim You need to link or replace above folder

Please install Nerd Fonts(I am using VictorMono) and kitty so font setting in GUI will work as expected

Startup nvim

If you saw error message "Error in packer_compiled: ..." Please press Enter, that will allow packer install the plugins. After all plugins install restart the nvim.

Note: The packages and data will be install to ~/.local/share/nvim

Please backup this folder if necessary

The setup needs nvim0.8+. For earlier release, please check packer branch. A patched nerd font is needed. Also if you start nvim from terminal, make sure it support nerdfont and emoji

missing sqlite, libsqlite3

Some of the plugin I am using depends on sqlite. By default sqlite was installed on MacOS. For other operating system, if you saw error message about sqlite, please following the instruction here to install sqlite

Install process


If you would like to sync to my branch. You can add you own setup in lua/overwrite folder

You can put your own plugins setup in modules/user folder


  • fish + spaceship + kitty. It is cooool and faster. nvim+kitty split view:

    vim_ide with nvim+kitty
