coc-clangd

coc-clangd

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

Quick Start

• install Node.js. coc.nvim and coc-clangd run on Node.js.
• install coc.nvim. Instructions using vim-plug (check out coc.nvim Wiki other options):
  • add to .vimrc: vim Plug 'neoclide/coc.nvim', {'branch': 'release'}
  • in vim, run :PlugInstall
• in vim, run :CocInstall coc-clangd
• coc-clangd will try to find clangd from your $PATH, if not found, you can run :CocCommand clangd.install to install the latest release from GitHub
• follow Project setup to generate compile_commands.json for your project

Note: If you've configured clangd as a languageServer in coc-settings.json, you should remove it to avoid running clangd twice!

Protocol extensions

clangd supports some extensions that are not in the official Language Server Protocol specification.

coc-clangd adds support for:

• Switching between header and implementation file: :CocCommand clangd.switchSourceHeader
  • You can open in split buffer by :CocCommand clangd.switchSourceHeader vsplit
• File status monitor, shows on NeoVim statusline
• Describe symbol under the cursor: :CocCommand clangd.symbolInfo
• Completions that adjust text near the cursor (e.g. correcting . to ->)

Configurations

:CocConfig opens your global coc-settings.json. :CocLocalConfig opens local configuration for your project ($PROJECTROOT/.vim/coc-settings.json)
