Key Mapping

You don't need to remember any key mapping, as navigation bar will show up immediately after the leader key (Space by default) is pressed.

Default <Leader> is Space, <LocalLeader> is ,. For example, Space s s search the word under cursor. As shown below, key mapping is carefully-chosen.

Most of key mapping is denite centric. More key mapping is listed here:

Basic Installation

Basic installation is simple:

pip3 install --upgrade pip neovim
git clone --recursive https://github.com/taohexxx/navim ~/.config/nvim

Make links if you are using Vim:

mv ~/.vim ~/.vim.backup
mv ~/.vimrc ~/.vimrc.backup
ln -s ~/.config/nvim ~/.vim
ln -s ~/.config/nvim/init.vim ~/.vimrc

Startup vim and dein will detect and ask you install any missing plugins.

Advanced Settings

Plugins are nicely organised in layers. There are many ready-to-use layers (javascript, navigation, scm, web, etc.) and you can add your own ones.

Private layers can be added to private_layers/. And Private plugins can be added to private_bundle/. The content of these two directory is ignored by Git.

It is completely customisable using a ~/.navimrc file. Just copy .navimrc.sample to ~/.navimrc and modify anything.

After restart Neovim (or Vim), run call dein#clear_state() || call dein#update() to apply changes.

Global Variables

In most instances, modify g:navim_settings in ~/.navimrc should meet your needs.

Use :echo g:navim_setting in Neovim (or Vim) to check for runtime settings.

Advanced Installation

macOS

YouComplete only support Neovim or MacVim.

Install Neovim (Recommended)

pip install --upgrade pip
pip3 install --upgrade pip
pip install --user --upgrade neovim
pip3 install --user --upgrade neovim
brew tap neovim/neovim
brew update
brew reinstall --HEAD neovim

Make alias

alias vi='nvim'
alias vim="nvim"
alias vimdiff="nvim -d"

If <C-h> does not work in neovim, add these line to ~/.zshrc

infocmp $TERM | sed 's/kbs=^[hH]/kbs=\\177/' > $TERM.ti
tic $TERM.ti

Execute the :UpdateRemotePlugins and restart Neovim.

Install MacVim

brew install macvim --with-luajit --override-system-vim

Make alias

alias vi="mvim -v"
alias vim="mvim -v"
alias vimdiff="mvim -d -v"

Install GLOBAL

brew install global

Select Auto Completion

Select auto completion plugins between Deoplete, Coc and YouCompleteMe.

• Deoplete: Zero configuration without LSP support. If you don't write C++ or Java, use this.
• Coc: Simple initialization with LSP support. If you write C++ or Java, use this.
• YouCompleteMe: Complicated initialization with LSP support. Not recommanded.

Auto Completion with Deoplete

Add this line to ~/.navimrc:

let g:navim_settings.completion_plugin = 'deoplete'

Auto Completion with Coc

Add this line to ~/.navimrc:

let g:navim_settings.completion_plugin = 'coc'

Install Node.js.

brew install node

Write your ~/.config/nvim/coc-settings.json. For example, using c++ with ccls:

{
  "languageserver": {
    "ccls": {
      "command": "ccls",
      "args": ["--log-file=/tmp/ccls.log"],
      "filetypes": ["c", "cpp", "cuda", "objc", "objcpp"],
      "rootPatterns": [
        ".ccls",
        "compile_commands.json",
        ".vim/",
        ".git/",
        ".hg/"
      ],
      "initializationOptions": { "cache": { "directory": ".ccls-cache" } }
    }
  },
  "suggest.triggerAfterInsertEnter": true,
  "suggest.noselect": false,
  "suggest.enablePreview": true,
  "suggest.minTriggerInputLength": 2,
  "suggest.acceptSuggestionOnCommitCharacter": true
}

You need to install coc extensions manually like this for the first time: :CocInstall coc-snippets coc-highlight coc-lists.

Using coc extensions.

Auto Completion with YouCompleteMe (Quick Compile)

Add this line to ~/.navimrc:

let g:navim_settings.completion_plugin = 'ycm'

Compile ycm_core

cd ~/.config/nvim/bundle/repos/github.com/Valloric/YouCompleteMe/
./install.sh --all
# or
# ./install.sh --clang-completer --go-completer --js-completer

Check for ~/.config/nvim/bundle/repos/github.com/Valloric/YouCompleteMe/third_party/ycmd/libclang.dylib and ~/.config/nvim/bundle/repos/github.com/Valloric/YouCompleteMe/third_party/ycmd/ycm_core.so, done

TypeScript Support

yarn global add typescript

Auto Completion with YouCompleteMe (Full Compile)

Try this if quick compile does not work.

Add this line to ~/.navimrc:

let g:navim_settings.completion_plugin = 'ycm'
