Tclh123's Vim config

Originaly forked from Maple's Vim config.

We use vundle to manage plugins.

Install

If you already have vim/ & .vimrc, backup them first.

mv ~/.vim ~/.vim.backup
mv ~/.vimrc ~/.vimrc.backup

Then, install,

cd dot-vimrc
./install.sh

CoC

Vim + Language servers

https://github.com/neoclide/coc.nvim

Install nvm, Node, yarn,

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
nvm install 14
npm install --global yarn

Install & Build coc.nvim,

# Run this command in vim, it will clone the coc.nvim repo into .vim/bundle
# :BundleInstall 'neoclide/coc.nvim'

# Build coc.nvim (a node project)
cd ~/.vim/bundle/coc.nvim
yarn install
yarn build

It will generate the config dir ~/.config/coc when you first start vim and loading the plugin.

clangd

For C++/C/Objective-C, (see https://github.com/neoclide/coc.nvim/wiki/Language-servers#supported-features)

Install clangd, (see https://clangd.llvm.org/installation),

• For Mac OS X, brew install llvm
• For others: Most distributions include clangd in a clangd package, in a clang-tools package, or in the full llvm distribution.

For centos/redhat, the following commands will install clangd 7 (too old).

# ref https://moevis.cc/quick-guide-to-install-clang-in-centos/

yum install -y centos-release-scl
yum install -y llvm-toolset-7.0-clang-tools-extra
source /opt/rh/llvm-toolset-7.0/enable

Build clangd from source,

git clone --depth=1 https://github.com/llvm/llvm-project.git

cd llvm-project
mkdir build && cd build

cmake --build `pwd` --target clangd -j8 && sudo cmake --install `pwd` --component clangd

• https://jdhao.github.io/2021/07/03/install_clangd_on_linux/

Use the vim command :CocConfig to open your user configuration file, and put

{
  "languageserver": {
    "clangd": {
      "command": "clangd",
      "rootPatterns": ["compile_flags.txt", "compile_commands.json"],
      "filetypes": ["c", "cc", "cpp", "c++", "objc", "objcpp"]
    }
  }
}

More clangd configuration https://clangd.llvm.org/config

coc-clangd (optional)

https://github.com/clangd/coc-clangd

The coc extension connects coc.nvim to the clangd language server.

# Run this in vim
:CocInstall coc-clangd

# It will download coc-clangd into ~/.config/coc/extensions/node_modules/

Generate compile_commands.json for clangd
