Configuration

Install vim-plug by running the following command.

curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

MacVim can share the same settings with vim, and also can use .gvimrc to set addtional GUI features.

Basic usage

C-w means CTRL-W

C-ww means CTRL-W_CTRL-W

C-w_c means CTRL-W_c

Open vim

vi -m <file>

Troubleshooting

Onivim

  • Holding down a key doesn’t repeat it (on 0.3.9 with osx) Run the following command in terminal. 
    defaults write com.extropy.oni ApplePressAndHoldEnabled -bool false

Neovim

  • Install with Homebrew

    brew install python
brew install neovim
/opt/homebrew/bin/python3 -m pip -U install neovim

  • Migrate from vim

    Runing the following commands to share the same configuration with vim.

    mkdir -p ~/.config/nvim
ln -s ~/.vimrc ~/.config/nvim/init.vim
ln -s ~/.gvimrc ~/.config/nvim/ginit.vim
mkdir -p ~/.local/share/nvim
ln -s ~/.vim ~/.local/share/nvim/site
echo "let g:python3_host_prog='<brew-path>/bin/python3'" >> ~/.vimrc

vim 8

solarized dark

  • Terminal.app

    Just use this configuration: solarized-dark.terminal

    Add export TERM=xterm-256color to .bashrc or .bash_profile

  • Putty

    Import solarized_dark.reg

    Connection -> Data -> Terminal-type string: xterm-256color

    Window -> Colours -> Allow terminal to use xterm 256-color

    Window -> Appearance -> Font: Menlo, 11 point

Plugins

coc.vim

Prerequisites:

brew install node
brew install yarn
npm install -g neovim

For vim-plug users:

Plug 'neoclide/coc.nvim', {'branch': 'release'}

Install extensions with :CocInstall coc-json coc-python.

coc extensions I’m using:

coc-clangd
coc-cmake
coc-css
coc-git
coc-html
coc-imselect
coc-json
coc-python (deprecated)
coc-pyright
coc-sh
coc-tsserver
coc-vimlsp
coc-vimtex

YouCompleteMe

One may confront this error: NoExtraConfDetected: No .ycm_extra_conf.py file detected, so no compile flags are available. Thus no semantic support for C/C++/ObjC/ObjC++. when install YCM with clang support. Here are some tips for install YCM with python2 or python3.

  • Do not use python of conda, confirming by which python.
    • For python2, use /usr/bin/python.
    • For python3, use /usr/local/bin/python3.
  • Compile YCM. 
    cd ~/.vim/plugged/YouCompleteMe
    • For python2, python install.py --clang-completer
    • For python3, python3 install.py --clang-completer
  • Use the example config file. 
    cp ~/.vim/plugged/YouCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py ~/.vim/plugged/YouCompleteMe/third_party/ycmd/cpp/ycm

vimtex

different engines

%! TEX program = pdflatex
%! TEX program = xelatex

One may manually reload vimtex in order to reset the program by <localleader>lx

root files

%! TEX root = /path/to/main.tex

backward search

Skim Perference => PDF-TeX Sync Support

  • neovim
    • Install the python modules pynvim and neovim-remote with brew’s pip3 (e.g., pip3 install pynvim neovim-remote).
    • Set let g:vimtex_compiler_progname='nvr' in your init.vim.

    • Set Skim sync options to:

      Preset Custom
      Command nvr
      Arguments --remote +"%line" "%file"

    Then backward search should work from both terminal neovim or the vimr GUI (or any other GUI).

    IMPORTANT: Skim must be started by vimtex (either through compiler callback or explicitly via <leader>lv) for backward sync to work! (This is how Skim “knows” which neovim instance – terminal or GUI – to sync to.)

    • Hold down the shift and command key and click on a point in the PDF document.

  • MacVim

    Preset Custom
    Command mvim
    Arguments --remote-silent +"%line" "%file"

LeaderF

If leaderF doesn’t respond, you can run :checkhealth in neovim to see whether pynvim has been properly installed. :LeaderFunction needs brew install ctags. :LeaderfRgInteractive needs brew install rg.

vim-grammarous

This plugin relies on LanguageTool which needs java to be excatuable. To do so, a Mac user can install java with brew and add /usr/local/opt/openjdk/bin to the PATH.

markdown-preview.nvim

~/.vim/plugged/markdown-preview.nvim/app/install.sh
