This configuration mainly focus on programming with C/Cpp, Golang, Rust and Python.

Quick Start

WARNING: The script uses the Homebrew to install dependencies. Please read it carefully before running it.

$ git clone https://github.com/Rlyown/nvim.git ~/.config/nvim
$ cd ~/.config/nvim
$ ./install.sh -i
$ nvim

Install

Make sure to remove or move your current nvim directory.

IMPORTANT Configuration based on neovim v0.10.0.

$ git clone https://github.com/Rlyown/nvim.git ~/.config/nvim

Requirements

• Neovim
• Lua (for neovim runtime)
• Rust (for some installations of dependencies)
• Python3 with pip and venv (for some plugins)
• Yarn (for markdown preview plugin)
• Golang 1.18 or higher (for some installations of dependencies and developments)
• Homebrew (for packages' installation in MacOS or Linux, but only for single user)

Install with following Steps:

First Step. Install the necessary packages, including environments in requirements.

• On MacOS

  NOTE: Homebrew is not necessary, you can install these packages through the tools provided by your current package-manager manually.

  # Runtime
  $ brew install neovim go python3 node@16 rust llvm lua yarn npm
  
  # Packages
  $ brew install ripgrep fd lazygit gnu-sed
  
  # Optional Packages
  $ brew install fortune bear llvm
  
  # If you want delete file to trash bin directory by nvim-tree
  $ brew install trash

  Nerd Fonts is needed to show icons. You can choose your favorite font or find icons in the https://www.nerdfonts.com.

  # Other nice fonts: Hack, Fira Code, Meslo
  $ brew tap homebrew/cask-fonts
  $ brew install --cask font-jetbrains-mono-nerd-font

  Note: Don't forget to change your terminal fonts.

• On Ubuntu

  NOTE:

  $ sudo snap install --classic nvim go rustup node
  $ sudo apt install lua5.3 ripgrep fd-find bat
  
  $ mkdir -p ~/.local/bin
  $ ln -s $(which fdfind) ~/.local/bin/fd
  $ export PATH=$HOME/.local/bin:$PATH
  
  # Make sure `~/go/bin` in your $PATH
  $ go install github.com/jesseduffield/lazygit@latest
  
  $ cargo install exa
  
  # Optional Packages
  $ brew install fortune bear

  Nerd Fonts is needed to show icons. You can choose your favorite font or find icons in the https://www.nerdfonts.com.

  # Other nice fonts: Hack, Fira Code, Meslo
  $ mkdir -p ~/.local/share/fonts
  $ cd ~/.local/share/fonts && curl -fLo "JetBrains Mono NL Regular Nerd Font Complete.ttf" https://github.com/ryanoasis/nerd-fonts/raw/master/patched-fonts/JetBrainsMono/Ligatures/Regular/JetBrainsMonoNerdFontMono-Regular.ttf

  Note: Don't forget to change your terminal fonts.

Optional Step. To set neovim as default editor, you can add these to ~/.bashrc or ~/.zshrc:

export VISUAL="nvim"
export EDITOR="nvim"

Final Step. Run nvim and wait for the plugins to be installed.

# First time to run nvim
$ nvim
# Or Synchronize all plugins manually
$ nvim --headless "+Lazy! sync" +qa
# Or Synchronize all plugins with specific version
$ nvim --headless "+Lazy! restore" +qa

# create neorg default directory
$ mkdir -p ~/.local/state/nvim/neorg-notes/work

Congratulations, now start enjoying the powerful neovim!

Check Health

Run nvim and type the following:

:checkhealth

You can see plugins' diagnose problems with your configuration or environment.

Tmux Integration

If you want to have a better experience with tmux, you can add the following bindings to your ~/.tmux.conf.

# To enable cycle-free navigation beyond nvim
is_vim="ps -o state= -o comm= -t '#{pane_tty}' | grep -iqE '^[^TXZ ]+ +(\\S+\\/)?g?(view|n?vim?x?)(diff)?$'"

bind-key -n 'C-h' if-shell "$is_vim" 'send-keys C-h' { if -F '#{pane_at_left}' '' 'select-pane -L' }
bind-key -n 'C-j' if-shell "$is_vim" 'send-keys C-j' { if -F '#{pane_at_bottom}' '' 'select-pane -D' }
bind-key -n 'C-k' if-shell "$is_vim" 'send-keys C-k' { if -F '#{pane_at_top}' '' 'select-pane -U' }
bind-key -n 'C-l' if-shell "$is_vim" 'send-keys C-l' { if -F '#{pane_at_right}' '' 'select-pane -R' }

bind-key -T copy-mode-vi 'C-h' if -F '#{pane_at_left}' '' 'select-pane -L'
bind-key -T copy-mode-vi 'C-j' if -F '#{pane_at_bottom}' '' 'select-pane -D'
bind-key -T copy-mode-vi 'C-k' if -F '#{pane_at_top}' '' 'select-pane -U'
bind-key -T copy-mode-vi 'C-l' if -F '#{pane_at_right}' '' 'select-pane -R'

# To resize the window
is_vim="ps -o state= -o comm= -t '#{pane_tty}' | grep -iqE '^[^TXZ ]+ +(\\S+\\/)?g?(view|n?vim?x?)(diff)?$'"

bind -n 'M-h' if-shell "$is_vim" 'send-keys M-h' 'resize-pane -L 1'
bind -n 'M-j' if-shell "$is_vim" 'send-keys M-j' 'resize-pane -D 1'
bind -n 'M-k' if-shell "$is_vim" 'send-keys M-k' 'resize-pane -U 1'
bind -n 'M-l' if-shell "$is_vim" 'send-keys M-l' 'resize-pane -R 1'

bind-key -T copy-mode-vi M-h resize-pane -L 1
bind-key -T copy-mode-vi M-j resize-pane -D 1
bind-key -T copy-mode-vi M-k resize-pane -U 1
bind-key -T copy-mode-vi M-l resize-pane -R 1

For more detail refer to usage of tmux.nvim.

Latex Integration

If you want to use latex, you can install Skim and VimTeX. VimTex has been installed by default. It only will be activated when executable latexmk be detected. You can install Skim with brew install --cask skim, and install Tex Live with brew install --cask mactex-no-gui in MacOS.

For more detail refer to Setting Up a PDF Reader for Writing LaTeX with Vim.

Different Input Method

In my configuration, ZFVimIM has been installed by default to support Chinese. You can just press ;; to switch between English and Chinese without changing input method on your computer or remote server.

For more detail or other languages refer to ZFVimIM.

Test Startup

# in neovim command line
:StartupTime
# or in normal mode
<leader><leader>s
# or just use vim builtin argument on terminal
$ nvim --startuptime startup.log

Alternatively, you can use a Go program to measure startup time of vim. https://github.com/rhysd/vim-startuptime.

# Installation
$ go install github.com/rhysd/vim-startuptime@latest
# Usage
$ vim-startuptime -vimpath nvim
